▼ Researchers develop radio to track plane in real time   [01-31-17]

Researchers have developed a reconfigurable radio to help ATC see in real time regarding the location of planes flying in air, even across oceans.

For designing and developing the new reconfigurable, higher bandwidth radio, NASA collaborated with Palm Bay based Harris Corporation.

Thanks to real time global tracking, planes can fly with less space and take more direct routes.

This will not only improve public safety, but save fuel cost too, because aircrafts no longer have to remain in particular airline traffic lanes.

The biggest point is the flexibility of the radio. Both its hardware and software are completely reconfigurable.

The company can rapidly and cheaply redesigning the radio to fit the needs of the aircraft.

It will be used to create first space-based global air traffic control system.

The air traffic control agencies will be able to see in real time the location and heading of every plane in the air.

For decades, airplanes have relied on radar surveillance via land-based radar stations. This has led to mishaps like the missing MH370.

A constellation of 66 satellites, owned by Iridium Communications Inc., goes into orbit equipped with AppSTAR radios.

The radios are programmed to receive signals from new airplane transceivers called ADS-B, which automatically send out a flight's number.

It also provides location, heading and other details.

Within seconds you can keep track of all the aircraft in the world.

System will go live in 2018.

▼ Pig and human stem cells combined to create transplantable organs   [01-31-17]

Scientists have grown embryos containing a combination of pig and human stem cells, possibly leading to growing transplantable organs.

Research remains at an early stage, but this is the first critical step. The ultimate aim is the growth of functional and transplantable tissues or organs.

Scientists have implanted adult human stem cells. These are called intermediate induced pluripotent stem cells. These have been combined with pig embryos and permitted to grow for four weeks.

The embryos a human animal mixture known as chimera after the mythical Greek species was terminated before it could be born.

Researchers found that human cells began to form into muscle tissue in pg embryos.

Notion of creating human animal mixtures has raised ethical questions. It could lead to the creation of animals with human qualities and intelligence.

Work will lead to understanding the evolution, development and disease and lead to remedy for organ shortages.

▼ Doomsday clock moves 30 seconds closer to midnight   [01-31-17]

US President Donald Trump's stand on nuclear weapons and climate change has made the world less safer, according to the Bulletin of Atomic Scientists.

The Doomsday Clock has consequently moved closer to midnight by 30 seconds. The clock is a metaphor for how close humanity has come to destroying the planet.

It was last changed in 2015 from 5 to 3 minutes before midnight.

It is now set at two and a half minutes to midnight following rise in strident nationalism across the world.

The factors that have influenced this, according to scientists comprising 15 Nobel laureates include strident nationalism, Trump's stand on nuclear arms and climate issues and a growing global insecurity.

On the nuclear issue, Trump also added that the US must build up its nuclear arsenal.

The last time the Doomsday clock was this closer was 63 years back in 1953 after the USSR exploded its first hydrogen bomb, creating the modern arms race.

The Doomsday Clock was created in 1947.

It has changed 19 times since then, ranging from two minutes to midnight in 1953 to 17 minutes before midnight in 1991.

▼ ISRO launches GSLV Mk III cryogenic engine   [01-30-17]

ISRO has successfully tested its indigenously developed cryogenic engine.

This is a major step forward for its landmark 'GSLV Mk III' rocket.

The rocket is scheduled for launch within the first quarter this year.

Cryogenic engines are used in the upper stage of a rocket launch.

They provide the maximum thrust to a launcher vehicle.

The cryogenic upper stage, designated as C25, was tested on January 25.

It was tested for 50 seconds at ISRO Propulsion Complex (IPRC) at Mahendragiri in Tamil Nadu.

This was the first test in a series of two tests. The next one was planned for a flight duration of 640 seconds.

The 50 second test is a significant milestone in the development of indigenous cryogenic propulsion technology.

Successful hot test of the stage in the first attempt itself demonstrates the agency's ability to work in new areas like cryogenic technology.

The development of C25 cryogenic stage began with the approval of GSLV MkIII.

This is the next generation launch vehicle of ISRO, capable of launching 4 ton class spacecraft in Geosynchronous Transfer Orbit (GTO).

The vehicle consists of two solid strap-on motors, one earth storable liquid core stage and the cryogenic upper stage.

The C25 stage is the most powerful upper stage developed by ISRO.

It uses Liquid Oxygen and Liquid Hydrogen propellant combination.

The stage carries 27.8 tons of propellants loaded in two independent tanks.

The first flight stage for 'GSLV MkIII-D1' mission is in an advanced stage of realisation.

It is scheduled to launch GSAT-19 during first quarter of 2017.

The flight engine has been successfully tested in the High Altitude Test facility.

It is integrated with the flight stage, ISRO said.

The C25 stage was conceptualised, designed and realised by Liquid Propulsion Systems Centre (LPSC), ISRO's lead Centre for Propulsion.

There is support from various System Development Agencies from other three Centres of ISRO -

  • Vikram Sarabhai Space Centre (VSSC),
  • ISRO Propulsion Complex (IPRC) and
  • Sathish Dhawan Space Centre (SDSC).

▼ TSRI scientists create first stable semi synthetic organism   [01-30-17]

Scripps Research Institute (TSRI), US scientists have created world’s first stable semi-synthetic organism.

This is a single-celled bacterium with an expanded genetic code

The semi-synthetic organism is the modified E.coli bacteria created by introducing DNA molecules.

These are not found in nature in a common bacterium.

Life’s natural genetic code only contains four natural bases- adenine (A), cytosine (C), guanine (G), thymine (T).

These bases pair forms two base pairs in the DNA ladder.

The newly created bacterium has two human-created X and Y bases that grow and divide, much like the four natural bases.

This single-celled organism can attach to the synthetic base pair as it divides.

The human-created X and Y base pair was dropped over time in the bacterium that limited the ways the it can use the additional information possessed in their DNA.

For this, researchers had optimised a tool called a nucleotide transporter.

This brings the materials necessary for the unnatural base pair to be copied across the cell membrane.

They discovered that modification to the transporter, made it much easier for the organism to grow and divide.

This is while holding on to X and Y.

Researchers used gene editing tool CRISPR-Cas9 to design the synthetic organism to see a genetic sequence without X and Y as a foreign invader.

Organisms with wholly unnatural attributes and traits that are not found elsewhere in nature can be created.

In future, it can help in creation of microbes capable of manufacturing entirely new proteins.

This is an innovation which can provide leads to new medicines and nanotechnology breakthroughs.

▼ NASA's New Horizon to explore Kuiper Belt object 2014 MU69   [01-27-17]

NASA's New Horizon spacecraft is set to explore small ancient object 2014 MU69 discovered by Hubble Space Telescope in 2014.

This object is located 1.6 billion km beyond Pluto.

The object is in the Kuiper Belt, a distant region that surrounds the solar system and is filled with trillions of icy rocks that have yet to be explored.

The spacecraft took about 16 months to beam back all of the data from the Pluto flyby and planetary scientists are studying the developments.

The next big stage of the mission, the flyby of 2014 MU69, will occur in January 2019.

MU69 is much smaller and more representative of the trillions of other KBOs.

Pluto is comparable to the size of North America at 2,370 km in diameter.

MU69 is less than 45 km across. It has a special kind of orbit that makes it possibly a type of object that is primordial and left over from early solar system formation.

About the Kuiper Belt

  • The Kuiper belt is sometimes called the Edgeworth–Kuiper belt.
  • It is a circumstellar disc in the Solar System beyond the planets.
  • It is extending from the orbit of Neptune (at 30 AU) to approximately 50 AU from the Sun.
  • It is similar to the asteroid belt, but it is far larger - 20 times as wide and 20 to 200 times as massive.
  • The Kuiper belt is home to three officially recognized dwarf planets: Pluto, Haumea, and Makemake.
  • Some moons, such as Neptune's Triton and Saturn's Phoebe, are also thought to have originated in the region.

▼ New medical testing for faster diagnosis of HIV, other diseases   [01-24-17]

Scientists have developed a new method for medical testing.

This may lead to faster diagnosis of HIV, Lyme disease, syphilis and rotavirus infections.

Researchers combined cutting-edge nanoscience with a magnetic process discovered more than 170 years ago to create the method for speedy medical tests.

The team coated nanoparticles with the antibody to BSA, or bovine serum albumin. This is an antibody which is commonly used as the basis of a variety of diagnostic tests.

By mixing the nanoparticles in a test solution, the BSA proteins preferentially bind with the antibodies coating the nanoparticles.

Nanoparticles were used with an iron core and applied a magnetic field to the solution, causing the particles to align in a particular formation.

As proteins bind to the antibody-coated particles, the rotation of the particles becomes sluggish, which is easy to discover with laser optics.

The discovery, if commercialised, could lead to faster test results for HIV, Lyme disease, syphilis, rotavirus and other infectious conditions.

At the core of the research are nanoparticles - tiny particles that are one-billionth of a meter.

Application of Faraday Rotation: Know More

  • The interaction of a magnetic field and light is known as Faraday rotation.
  • This is a principle discovered by scientist MichaelFaraday in 1845.
  • Putnam adapted it for biological use.
  • Method could be used to produce biochemical immunology test results in as little as 15 minutes, compared to several hours for ELISA, or enzyme-linked immunosorbent assay.
  • This is currently a standard approach for biomolecule detection.

▼ Robotic heart sleeve to help human heart beat!   [01-23-17]

Harvard researchers along with scientists from Boston Children's Hospital have developed a customizable robotic heart sleeve that helps hearts to beat.

This opens up new treatment for heart failure patients.

Soft robotic sleeve twists and compresses in sync with a heart beat. This augments cardiovascular functions weakened by heart failure.

Current available devices that help heart beat directly come in contact with blood.

The soft robotic sleeve does not directly contact blood, lowering the risk of clotting.

It also eliminates the need for blood thinner medication. The latter can be dangerous.

Device can help patients transplant or aid in cardiac rehab and recovery.

This showcases the potential of soft robotics to meet clinical needs.

The inventor of the heart sleeve is Ellen T. Roche and her team.

The research, was a collaboration between Harvard, the Wyss Institute, and Boston Children’s Hospital.

It shows how soft robotics can safely interact with soft tissue and lead to improvements in cardiac function.

The thin silicone sleeve uses soft pneumatic actuators placed around the heart.

It mimics the outer muscle layers of the mammalian heart.

The actuators twist and compress the sleeve in a motion akin to the beating heart.

The device is tethered to an external pump. This uses air to power the soft actuators.

The sleeve can be customized for each patient, as his/her condition evolves.

The sleeve is attached to the heart using a combination of a suction device, sutures, and a gel interface.

This helps with friction between the device and the heart.

Heart Failure: Know More

  • Heart failure affects 41 million people worldwide.
  • Today, some of the treatment options are mechanical pumps called ventricular assist devices (VADs).
  • These pump blood from the ventricles into the aorta, and heart transplants.
  • While VADs are continuously improving, patients are still at high risk for blood clots and stroke.

▼ Smart needle helps neurosurgeons see where they insert the needle   [01-23-17]

Scientists have developed a new smart needle with a tiny camera that permits surgeons to see at-risk blood vessels. They can avoid injuring these.

The advance is set to make brain surgery safer.

The minute imaging probe encased with a brain biopsy needle ensures that surgeons see blood vessels while inserting the needle.

This will help them to avoid bleeds that can have the potential to be fatal.

It is a smart needle with a tiny fibre optic camera the size of a human hair. It shines infrared light to see the vessels before the needle can cause any damage.

Computer itself attached to the smart needle recognises blood vessels and alerts the surgeon. Smart needle will be ready for clinical trials in the coming year.

To have a tool that recognises blood vessels as one proceeds through the brain would revolutionise neurosurgery.

It will increase the chances of safer surgery.

▼ Wolf 1061c: Potential habitable exoplanet discovered   [01-23-17]

Astronomer Stephen Kane from San Francisco State University, US has studied an exoplanet called Wolf 1061c .

It was found that it could be habitable. Its orbit changes at a faster rate unlike Earth, which may cause its climate to be quite chaotic.

His study was focused on finding “habitable zones” where water could exist in a liquid state on a planet’s surface.

The planetary system of Wolf 1061c is located 14 light years away.

One of the three known planets in the Wolf 1061 system, a rocky planet called Wolf 1061c, is entirely within the habitable zone.

When scientists search for planets that could sustain life, they are basically looking for a planet with nearly identical properties to Earth.

According to Kane, life is possible on Wolf 1061c under one possibility - the short time scales over which Wolf 1061c's orbit changes could be enough that it could actually cool the planet off.

Exoplanet: Know More

  • It is a planet that does not orbit the Sun and instead orbits a different star, stellar remnant, or brown dwarf.
  • It is also termed as extrasolar planet.
  • Starting in 1988, and as of 22 January 2017, there have been 3,565 exoplanets in 2,675 planetary systems.
  • Around 602 multiple planetary systems confirmed.
  • HARPS (since 2004) has discovered about a hundred exoplanets while the Kepler space telescope (since 2009) has found more than two thousand.
  • Kepler has also detected a few thousand candidate planets.

▼ ISRO realigns MOM orbit to prevent impact of eclipse   [01-20-17]

Indian Space Research Organisation has successfully realigned the orbit of its Mars Orbiter Mission 'Mangalyaan.'

The aim is to ensure that the study is not affected by long-duration eclipse.

The duration of the eclipse was so long that the Mangalyaan's battery capacity would have got exhausted due to lack of sun rays.

ISRO therefore, manoeuvred to change the orbit of Mangalyaan and reduced the duration of eclipse.

MOM still has 30kg fuel left, and with realignment it will work longer.

The correction in the trajectory of Mangalyaan was required to keep the power supply strong during the eclipse.

It is caused by shadow of Mars falling on it for 7-8 hours so that it could continue to function longer.

This is because Mangalyaan's battery cannot support long-duration eclipse.

▼ Astronomers find 2 trillion galaxies in the universe   [01-18-17]

The universe contains around 2 trillion galaxies, ten times more than previously thought according to a new study.

Astronomers have sought to study how much the number of galaxies are in the observable universe equals.

Scientists have used images from Hubble Space Telescope to estimate that the universe contains 100-200 billion galaxies.

Presently, technology permits just 10 percent of these galaxies to be studied and remaining 90 percent will be seen once bigger and better telescopes are developed.

Pencil beam images of deep space from telescopes around the world, and especially from the Hubble telescope, were converted into 3D maps.

This permits the density of the galaxies as well as volume of one small region of space following another to be studied.

Like an intergalactic archaeological dig, the research has enabled the team to establish how many galaxies have been missed.

Results of the study are based on the measurement of number of observed galaxies at different epochs through the universe history.

The scientists have examined how many galaxies there were at a given epoch they found that were significantly more at earlier times.

When the universe was a few billion years old, there were 10 times as many galaxies in a given volume of space as there were within a similar volume in present times.

Most galaxies are low mass systems with masses similar to those of the satellite galaxies surrounding the Milky Way.

Over 13.7 billion years of cosmic evolution since the Big Bang saw galaxies that have been growing through star formation and merger with other galaxies.

This suggests significant evolution must have occurred to reduce their number through extensive merging of systems.

The technique works on using molecules with dyes that glow under certain kinds of light, the principle behind so-called "black light" images.

Fluorescent imaging can assist scientists to understand which molecules are produced in large amounts in cancer or other diseases.

The information that may be useful in diagnosis or in identifying possible targets for therapeutic drugs.

Biological research is now moving to complex systems like these, which track multiple targets.

HySP can look at many different molecules in one pass.

Additionally, the algorithm effectively filters through interference to discern the true signal, even if that signal is extremely weak.

Clinicians may be able to use HySP to analyze cell phone pictures of skin lesions to detect cancer and diagnose it.


  • It is much faster and far less expensive than current techniques.
  • It may be useful for diagnosing.
  • It also helps in monitoring diseases.
  • It is convenient to use through cell phone images.

▼ E-waste rises by 63% in 5 years in Asia: UN report   [01-16-17]

Electronic waste or e-waste is rising sharply across Asia. Higher incomes allow millions of people to buy smartphones and other gadgets with serious problems for human health and the environment.

The UN study has found e-waste in Asia has jumped 63 percent in 5 years. A report by the United Nations University also warned of the need to improving recycling and disposal methods.

Many countries lack infrastructure for eco-friendly e-waste management. Increasing volumes are a cause for concern, according to the UN University's Sustainable Cycles Programme.

China and other nations in Asia are dumping grounds for e-waste from developed nations. The Asian nations recycle the waste in unsafe but ultra cheap backyard factories.

Asia has emerged as a source of increasing e-waste with affluent customers also buying items such as phones, tablets, personal computers and TVs.

China alone has doubled its generation of e-waste between 2010 and 2015 according to the report.

Per capita, the worst economy in the region is Hong Kong. Each person in this Chinese region generates 21.7 kg or 47.8 pounds of e-waste in 2015.

Singapore and Taiwan are also leading in e-waste, with 19 kg per person generated in 2015.

The lowest e-waste generators were Vietnam, Philippines and Cambodia. These nations averaged 1 kg of electronic waste per person.

Fighting illegal dumping is a must. Improper e-waste generates toxic chemicals which cause severe health and environmental consequences.

Acids to separate metals in e-waste are dangerous and this exposure can lead to serious health problems.

For example, a Chinese town Guiyu which build its economy on overseas e-waste recycling is facing toxic water and air contamination. High lead levels are found in the blood of the residents.

Electronic remnants were also strewn in the stream and led to danger in terms of contaminating the water supply.

▼ Silicon likely to be the mystery element in earth's inner core!   [01-13-17]

Japanese scientists have said that silicon is likely to be the mystery element in the inner core of the earth. This could solve one of the biggest secrets of the planet.

Consensus has long been that centre of the planet comprises:

  • Iron-85%
  • Nickel-10%
  • Sulphur, Oxygen and Silicon-5%
But Japanese scientists have found that iron nickel alloys mixed with silicon were able to sustain pressure and temperature found in the inner core of the earth.

Data for the mixed material observed with X-rays matched seismic data namely sound velocity, or seismic waves obtained for the inner core.

Finding could reveal if earth was rich in oxygen before photosynthesis.

Oxygen has been listed as another potential candidate for mystery element in the inner core.

About the Layers of the Earth
  • Earth is composed of three main layers: outer layer, mantle and core.
  • Outer layer is solid where creatures reside.
  • Mantle is composed of hot magma and other semi solid materials.
  • Core is composed of outer layer of liquid iron and nickel and inner layer - a hot dense ball of mostly iron.

▼ Retroviruses like HIV may be half a billion years old   [01-11-17]

Retroviruses, a family of viruses that include HIV are half a billion years old, according to scientists.

New research indicated retroviruses have ancient marine origins. They have been with animal hosts through the revolutionary transition from sea to land.

Up till now, it was believed these viruses were just 100 million years in age. Research shows retroviruses are 450 million years old and possibly older.

They may have originated with veterbrate hosts in the early Paleozoic era.

Present in vertebrate ancestors before land colonisation, they have accompanied hosts through transition from sea to land.

What are Retroviruses?

  • A genre of viruses that cause chronic diseases like AIDS, cancer and autoimmune disorders.
  • The 'retro' part of their name comes from the fact they are made of RNA.
  • RNA is converted into DNA and inserted into their host genome.
  • Genomic fossils for foamy-like retroviruses were found in highly diverse hosts.
  • These are including ray-finned fish and amphibians.

▼ Two most powerful universe phenomena discovered by GMRT   [01-9-17]

Astronomers, using data from India’s Giant Metrewave Radio Telescope (GMRT), have discovered two of the most powerful phenomena in the universe – a supermassive black hole and the collision of giant galaxy clusters about two billion light years from Earth.

The two phenomenon have combined to create a stupendous cosmic particle accelerator, researchers said and they found what takes place when matter ejected by a giant black hole is swept up in the merger of two enormous galaxy clusters.

This is the first time, however, that we see them clearly linked together in the same system and the cosmic double whammy is found in a pair of colliding galaxy clusters called Abell 3411 and Abell 3412 located about 2 billion light years from Earth.

The two clusters are both very massive, each weighing about a quadrillion - or a million billion - times the mass of the Sun.

The powerful electromagnetic fields associated with this structure have accelerated some of the inflowing gas away from the vicinity of the black hole in the form of an energetic, high-speed jet.

These accelerated particles in the jet were accelerated again when they encountered colossal shock waves – cosmic versions of sonic booms generated by supersonic aircraft -produced by the collision of the massive gas clouds associated with the galaxy clusters.

This discovery solves a long-standing mystery in galaxy cluster research about the origin of beautiful swirls of radio emission stretching for millions of light years, detected in Abell 3411 and Abell 3412 with the GMRT.

The galaxy clusters are known as Abell 3411 and Abell 3412, which are located about two billion light years from Earth.

Based on data obtained from the Chandra X-ray Observatory, the Giant Metrewave Radio Telescope (GMRT) in India, the Karl G. Jansky Very Large Array, the Keck Observatory, and Japan’s Subaru Telescope, the team was able to capture this event.

It was captured in the optical, x-ray, and radio wave wavelengths.

▼ NASA builds road maps for Voyager spacecrafts   [01-9-17]

NASA's Hubble Space Telescope is set to create a roadmap for two Voyager spacecrafts that will travel through unexplored territories beyond the solar system, by measuring the material along the future trajectories of the probe.

When Voyagers run out of power and are unable to send back new data, Hubble will still be able to tap them to learn more about their environment.

A preliminary analysis of the Hubble observations shows a rich, complex interstellar ecology, containing multiple clouds of hydrogen laced with other elements.

This also provides new data into how the sun travels through interstellar space.

This is a great opportunity to compare data from in situ measurements of the space environment by the Voyager spacecraft and telescopic measurements by Hubble.

The astronomers hope that the Hubble observations will help them characterise the physical properties of the local interstellar medium. Synthesising these insights with in situ measurements from Voyager would provide an unprecedented overview of the local interstellar environment.

For the next 10 years, the Voyagers will be making measurements of interstellar material, magnetic fields and cosmic rays along their trajectories.

About Voyager Spacecrafts

  • NASA launched the win Voyager 1 and 2 spacecrafts in 1977.

▼ Lucy and Psyche - New asteroid missions from NASA   [01-9-17]

NASA has announced that it will provide complete funding under the Discovery Program for two missions focusing on different kinds of asteroids.

A mission called Lucy will take off in 2021 to study a plethora of asteroids, including one in the main asteroid belt between Mars and Jupiter, along with size others among space rocks in Jupiter's orbit.

A mission Psyche will be launched in 2023 to visit a type of asteroid never seen closely before - a huge metallic object called 16Psyche that corresponds in composition to the core of the earth.

NASA will also provide funding for the Near Earth Object Camera designed to look for potentially hazardous asteroids in the region of space closest to the orbit of the earth.

Discovery Program missions are low-cost space science efforts, capped at USD 450 million. Before, selected discovery missions included:

  • Messenger probe to Mercury
  • Dawn probe to the asteroids Vesta and Ceres
InSight lander, which is due to begin its trip to Mars next year.

Lucy, Psyche and NEOCam were among the finalists for this year. Two missions to Venus– DAVINCI and VERITAS– lost out on the round, but could be reconsidered in the future.

Psyche Mission

This mission aims to explore one of a kind metal asteroid 16Psyche. It will be launched in 2023. Most steroids are rocky or covered in ice. 16Psyche is thought to be composed of nickel and iron, much like the core of the earth.

This is a one of a kind object in the main asteroid belt. 16Psyche is a 130 mile wide chunk of material thought to be composed of metallic iron and nickel, and could be the exposed core of a Mars sized planet which lost its outer layer in collisions billions of years ago.

Mission schedule calls for launch in Oct 2023, earth gravity assist manouver in 2024, a Mars FlyBy in 2025 and arrival at the asteroid in 2023.

The probe will study the asteroid's composition, mass distribution and magnetic field over a two year period.

16Psyche is the only known object of its kind in the solar system and the only way humans will visit a core.

Psyche also intrigues asteroid miners because the composition of the metal bearing space object could pave the way for other resources.


Lucy mission has been named after a famous, critical hominin fossil found in Ethiopia in 1974. It will be launched in 2021 and involves sending robotic spacecrafts to study Jupiter's trojan asteroids.

These asteroids are believed to be relics of an earlier era in the history of the solar system. Lucy is due for launch in Oct 2021 and will reach the first destination in the main belt in 2025. The problem will study six Jupiter Trojan asteroids between 2027 and 2033.

Trojans are thought to be remnants of the early solar system that were gravitationally captured at balance points in the orbit of Jupiter.

The small bodies are fossils of planet formation and that is Lucy has been named after a fossil.

Lucy's target in the main asteroid belt is Donaldjohanson, in memory of the paeleontologist who discovered the famous 3.2 million year old fossil in 1974.

Other targets include Trojan asteroid Eurybates, and the binary trojan Patroclus-Menoetius.

Discovery Program Missions: Know More
  • Both the asteroid missions will unravel the origin and evolution of the solar system.
  • This puzzle will understand how the sun and its family of planets changed over time and where life could be developed and sustained.
Five proposals were selected initially for this mission, including the following:

i. Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI),

ii. Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy mission (VERITAS).

iii. Near Earth Object Camera was another project proposed; it has been granted an extra year of funding.

iv. NASA will not be observing bodies with atmospheres.

▼ Heal wounds without scars   [01-9-17]

In a massive breakthrough, researchers have a found a way to manipulate wounds to heal as regenerated skin, rather than scar tissue.

By transforming the most common type of cells found in wounds into fat cells, scientists have carried out a breakthrough.

Fat cells called adipocytes are generally found in the skin, but they are lost when wounds heal following scarring.

The most common cells found in healing wounds are myofibroblasts thought to form only a scar. Scar tissue lacks hair follicles which is another factor that grants it an abnormal appearance from the remainder of the skin.

Researchers at US University of Pennsylvania based their work on changing the myofibroblasts into fat cells that are not associated with scarring.

The wound healing can be manipulated so it leads to skin regeneration rather than scarring. The aim is to regenerate hair follicles before. Once that occurs, the fat will regenerate in response to signals from these follicles.

The study has also shown hair and fat may develop separately, but not independently. Hair follicles form first. Additional factors are produced by the regenerating hair follicle to convert the surrounding myofibroblasts to regenerate as fat instead of forming a scar.

The fat will not form in the absence of new hair, but once it does, the new cells cannot be distinguished from the pre-existing fat cells. This gives the wound a natural look while healing, instead of leaving a scar.

Researchers identified a BMP or Bone Morphogenetic Protein that instructs myofibroblasts to become fat. This signaling forms the basis of the breakthrough.

Myofibroblasts were initially thought to be incapable of becoming a different type of cell. But the work of these scientists shows that we have the ability to influence these cells and they can be efficiently and stably converted to fat cells.

Adipocyte cells are lost naturally because of the aging process, especially in the face which leads to permanent, deep wrinkles. Anti-aging treatment cannot fix this in a satisfactory way.

▼ New human organ mesentery found in the digestive system   [01-6-17]

Scientists have discovered what is known as a new human organ in the digestive system. It is called mesentery.

The organ was previously believed to consist of fragmented and disparate structures. Researchers found, however, that it is one continuous organ and outlined evidence to classify it as such in a review published recently.

J. Calvin Coffey a researcher from University Hospital Limerick in Ireland who first made the discovery has said they have an organ in the body which has not been acknowledged to date.

Coffey, a professor at the University of Limerick, reclassified the mesentery after discovering it was contiguous. His findings were published in November in the medical journal The Lancet Gastroenterology and Hepatology.

Whether the mesentery should be viewed as part of the intestinal, vascular, endocrine, cardiovascular or immunological systems is so far unclear as it has important roles in all of them.

Mesentery research goes back to the time of Leonardo DaVinci, who provided one of the earliest depictions of the mesentery, which was shown as contiguous.

For centuries, the new-organ was depicted that way until the findings of Treves in 1885. His description of the mesentery - which was disconnected - became the basis of medical literature.

About the Mesentery

  • It is a double fold of peritoneum, the lining of the cavity in the abs.
  • It connects the intestine to the abdomen.
  • Mesentery plays a central position in the body.
  • Among its functions, it carries blood and lymphatic fluid between the intestine and the rest of the body.
  • It also maintains the position of the intestine.
  • It ensures that it’s connected with the abdominal wall without being in direct contact.
  • It has a spiral formation in the abdomen.
  • It is packaged along a spinal trajectory, starting in the upper abdomen and ending in the pelvis.

▼ Tuticorin based plant makes baking soda from Carbon dioxide!   [01-4-17]

A breakthrough make useful products out of planet-heating CO2 emissions has been attained.

A plant at the S. Indian industrial port of Tuticorin is capturing CO2 from its own coal-powered boiler.

It is using it to make soda ash or baking powder.

The technology is running without subsidy which is a major advancement for carbon capture technology.

Firm says chemicals will lock up to 60 thousand tonnes of CO2 per year.

Tuticorin plant is the first industrial scale example of CCU/carbon capture and utilisation.

This expands the market for CO2 as a chemical raw material.

Stripping CO2 from low concentrations in flue gas was tough.

Indian plant called Tuticorin Alkali Chemicals uses a new CO2 stripping chemical developed by IIT investors at Carbonclean.

Less energy is required for this carbon capture technology which is less corrossive and requires smaller equipment.

The soda ash is a base chemical with a wide range of uses including glass manufacture, sweeteners, detergents and paper products.

Carbonclean believes capturing usable CO2 can deal with perhaps 5-10% of the world’s emissions from coal.

By producing a subsidy-free carbon utilisation project, Carbonclean has made rapid strides in CCU technology.

▼ Lefamulin: Drug molecule that combats antibiotic resistant pathogens   [01-4-17]

Researchers from Israel headed by Nobel laureate Ada E. Yonath is set to develop an effective drug to fight disease resistant pathogens,

The genetic solution to the menace of antibiotic resistance to a plethora of diseases such as TB and hospital acquired infections, it targets a bacteria called methicillin-resistant Staphylococcus aureus (MRSA).

Pathogens developing resistance to antibiotics are a real threat.

The novel molecule called Lefamulin has been found to treat diseases resistant to set of antibiotics.

This drug targets pneumonia.

Staphylococcus aureus is fast developing resistance.

This is causing new infections to patients.

Role of ribosomes to develop new generation antibiotics is being highlighted.

What are Antibiotics Drugs?

Antibiotics and similar drugs, together are called antimicrobial agents.

They have been used for the last 70 years to treat patients who have infectious diseases.

Since the 1940s, these drugs have greatly reduced illness and death from infectious diseases.

But, with the rise of antimicrobial resistance, the drugs are losing their impact.

▼ Know all about the Agni IV   [01-3-17]

Agni-IV was launched on 2nd Jan 2016. This comes after India tested Agni-V the country's longest

range nuclear capable missile.

India has a series of nuclear-capable missiles like Prithvi series, Agni series and the Submarine Launched Ballistic Missile.

Agni-IV is a nuclear-capable missile with a range of 4,000 km while Agni-V has a range of 5,000 km.

Both missiles can cover most parts of China.

Agni-IV missile is 20m tall and weighs 17 tons.

It was launched from the integrated test range at Abdul Kalam Island or Wheeler Island.

This was the sixth trial of the Agni-IV missile.

The previous test was conducted on Nov 9 2015.

The fire and forget missile is navigated using a jam proof ring laser gyroscope. This enables avioncs to function with temperatures below 50 degree centigrade inside.

Agni-IV also has a 5th generation on board computer and distributed architecture.

It has the latest feature to correct and guide itself for in-flight disturbances.

Sophisticated surface-to-surface missile has modern avionics to provide high reliability level.

The vehicle reaches the target within 2 digit accuracy.

The indigenously developed surface-to-surface Agni-IV missile is a two stage weapon system.

Agni I, II and III as well as Prithvi has been in an arsenal of armed forces, giving them a reach of over 3,000 kms and providing the country effective deterrence capability.

Missile posses submarine launch capability as well.

The missile can be fired from locations deep in the Indian hinterland making it tough for enemies to track and destroy it.

▼ NASA adds leap second to its missions   [01-2-17]

To maintain accuracy, NASA said its missions, including the Solar Dynamics Observatory, or SDO, which continuously watches the sun, will join official clocks around the world in adding a leap second to the final minute of 2016.

On December 31, 2016, official clocks around the world will add a leap second at 23 hours, 59 minutes and 59 seconds Coordinated Universal Time (UTC).

Clocks do this to keep in sync with Earth's rotation, which gradually slows down over time. When the dinosaurs roamed Earth, for example, our globe took only 23 hours to make a complete rotation. In space, millisecond accuracy is crucial to understanding how satellites orbit.

SDO moves about 1.9 miles every second. So does every other object in orbit near SDO. We all have to use the same time to make sure our collision avoidance programs are accurate. So we all add a leap second to the end of 2016, delaying 2017 by one second.

The leap second is also key to making sure that SDO is in sync with the Coordinated Universal Time used to label each of its images.

Designed to help us understand the sun's influence on Earth and Near-Earth space, SDO was launched in 2010.

It has a clock that counts the number of seconds since the beginning of the mission.

To convert that count to UTC requires knowing just how many leap seconds have been added to Earth-bound clocks since the mission started.

When the spacecraft wants to provide a time in UTC, it calls a software module that takes into consideration both the mission's second count and the number of leap seconds and then returns a time in UTC.

UTC - Coordinated Universal Time

  • Coordinated Universal Time (UTC) is the basis for civil time today. This 24-hour time standard is kept using highly precise atomic clocks combined with the Earth's rotation
  • UTC is the time standard commonly used across the world. The world's timing centers have agreed to keep their time scales closely synchronized - or coordinated - therefore the name Coordinated Universal Time.
  • Universal Time (UT) was created at the Washington Meridian Conference in 1884. This is the basis for the 24-hour time zone system known today.

  • Two components are used to determine UTC

  • International Atomic Time (TAI)
  • Universal Time (UT1)

▼ Red planet Mars has purple rocks: NASA   [01-2-17]

Curiosity Rover from NASA has captured an up-close image of the red planet's mountainous landscape, with purple-coloured rocks littered across the foreground.

Images are from Mast Camera (Mastcam) on Curiosity Mars rover showing purple-hued rocks near the rover's late-2016 location on lower Mount Sharp.

Variations in colour of the rocks hint at the diversity of their composition on lower Mount Sharp, NASA said.

The purple tone of the foreground rocks has been seen in other rocks where Curiosity's Chemical and Mineralogy (CheMin) instrument has detected hematite, it said.

Winds and windblown sand in this part of Curiosity's traverse and in this season tend to keep rocks relatively free of dust, which otherwise can cloak rocks' colour.

The three frames combined into a mosaic were acquired by the Mastcam's right-eye camera on November 10, during the 1,516th Martian day, or sol, of Curiosity's work on Mars.
