                                                     WE LOVE SCIENCE HERE

     THIS  IS A WAR ZONE WHERE SCIENCE FIGHTS WITH NONSENSE AND WINS                                               

“The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.”             

                    "Being a scientist is a state of mind, not a profession!"

"Knowledge is a Superpower but the irony is you cannot get enough of it with ever increasing data base unless you try to keep up with it constantly and in the right way!" The best education comes from learning from people who know what they are exactly talking about.

Science is this glorious adventure into the unknown, the opportunity to discover things that nobody knew before. And that’s just an experience that’s not to be missed. But it’s also a motivated effort to try to help humankind. And maybe that’s just by increasing human knowledge—because that’s a way to make us a nobler species.

If you are scientifically literate the world looks very different to you.

We do science and science communication not because they are easy but because they are difficult!

Scientists have created a device that can literally extract water from the air using solar power which could one day provide “personalized water” to those in areas affected by chronic drought.

Researchers at Massachusetts Institute of Technology (MIT) and the University of California Berkeley published their findings in the journal Science on 13th April, 2017.

The invention can harvest water from the atmosphere in conditions where relative humidity is as low as 20 percent, which makes it potentially usable in many of the planet's driest regions.

Atmospheric water is a resource equivalent to ~10% of all fresh water in lakes on Earth. However, an efficient process for capturing and delivering water from air, especially at low humidity levels (down to 20%), has not been developed. Now the scientists report the design and demonstration of a device based on porous metal-organic framework-801 [Zr6O4(OH)4(fumarate)6] that captures water from the atmosphere at ambient conditions using low-grade heat from natural sunlight below one sun (1 kW per square meter). This device is capable of harvesting 2.8 liters of water per kilogram of MOF daily at relative humidity levels as low as 20%, and requires no additional input of energy.

Personalised cancer treatment ...

  • Drugs need to be specific for each patient’s genetic and immunological profile

  • Side-effects of medication can be predicted by first testing them on stem cells

  • The studies could lead to mapping of ethno-specific adverse effects of cancer drugs

Turbulence strong enough to injure airline passengers and crew could become twice as common because of climate change, a study has found.

Thousands of people are hurt during flights each year as turbulence causes aircraft to rise or fall rapidly without warning. Most cases are minor but there are hundreds of serious injuries and dozens of deaths, mainly on small planes.

Rising carbon dioxide emissions are increasing the temperature difference between bands of air at cruising altitude, according to research by the University of Reading. This strengthens the jet stream, the ribbon of strong winds which flows from west to east around the planet.

The acceleration of the jet stream is causing it to become less stable. Layers of air within it move at different speeds and this difference is increasing as the planet warms, producing more turbulence for aircraft.

The researchers found that the growth in the amount of CO2 in the atmosphere expected by 2050 could increase severe turbulence by at least 85 per cent.

During such severe turbulence, an aircraft’s altitude can deviate suddenly by around 100ft up or down, causing anyone unbuckled and any unsecured object to be thrown around the cabin.

The study, published in the journal Advances in Atmospheric Sciences, said that increased turbulence might not result in a rise in injuries if airlines became better at forecasting it and taking avoiding action.

A Graphene-Based Sieve That Turns Seawater Into Drinking Water

We need drinking water but with the ever shrinking drinkable water sources, we have to make do with saline water available abundantly in seas and oceans across the world. Scientists now have found a way to convert sea water to pure water.
The invention of a graphene-oxide membrane that sieves salt right out of seawater is unique.

At this stage, the technique is still limited to the lab, but it's a demonstration of how we could one day quickly and easily turn one of our most abundant resources, seawater, into one of our most scarce - clean drinking water.

The team, led by Rahul Nair from the University of Manchester in the UK, has shown that the sieve can efficiently filter out salts, and now the next step is to test this against existing desalination membranes.
Graphene-oxide membranes have long been considered a promising candidate for filtration and desalination, but although many teams have developed membranes that could sieve large particles out of water, getting rid of salt requires even smaller sieves that scientists have struggled to create.

One big issue is that, when graphene-oxide membranes are immersed in water, they swell up, allowing salt particles to flow through the engorged pores.

The Manchester team overcame this by building walls of epoxy resin on either side of the graphene oxide membrane, stopping it from swelling up in water.
This allowed them to precisely control the pore size in the membrane, creating holes tiny enough to filter out all common salts from seawater.

The key to this is the fact that when common salts are dissolved in water, they form a 'shell' of water molecules around themselves.

"Water molecules can go through individually, but sodium chloride cannot. It always needs the help of the water molecules," Nair said.

"The size of the shell of water around the salt is larger than the channel size, so it cannot go through."

Not only did this leave seawater fresh to drink, it also made the water molecules flow way faster through the membrane barrier, which is perfect for use in desalination.

"When the capillary size is around one nanometre, which is very close to the size of the water molecule, those molecules form a nice interconnected arrangement like a train," Nair explained .

"That makes the movement of water faster: if you push harder on one side, the molecules all move on the other side because of the hydrogen bonds between them. You can only get that situation if the channel size is very small."

Graphene oxide is also a lot easier and cheaper to make in the lab than single-layers of graphene, which means the technology will be affordable and easy to produce.

Particles that cover the surface of Saturn's largest moon, Titan, are "electrically charged" and can cling together for months, scientists have found for the first time.

When the wind blows hard enough, Titan's non-silicate granules get kicked up and start to hop in a motion referred to as saltation. As they collide, they become frictionally charged, like a balloon rubbing against your hair, and clump together in a way not observed for sand dune grains on Earth - they become resistant to further motion. They maintain that charge for days or months at a time and attach to other hydrocarbon substances, much like packing peanuts used in shipping boxes here on Earth.

"If you grabbed piles of grains and built a sand castle on Titan, it would perhaps stay together for weeks due to their electrostatic properties," said Josef Dufek, from Georgia Institute of Technology in the US.

"Any spacecraft that lands in regions of granular material on Titan is going to have a tough time staying clean. Think of putting a cat in a box of packing peanuts," Dufek. The electrification findings may help explain an odd phenomenon. Prevailing winds on Titan blow from east to west across the moon's surface, but sandy dunes nearly 300 feet tall seem to form in the opposite direction.

"These electrostatic forces increase frictional thresholds," said Josh Mendez Harper, a doctoral student at Georgia Tech. "This makes the grains so sticky and cohesive that only heavy winds can move them. The prevailing winds aren't strong enough to shape the dunes," said Mendez Harper.

The findings have just been published in the journal Nature Geoscience.

Good news for people who dye their hair...Safer Hair Dye

You no more need to worry about allergic reactions while dying your hair. Because Researchers from Gyeongsang National University have mimicked melanin to produce a dye that is less allergenic than the existing chemical used to dye hair black. Their report appears in the journal ACS Biomaterials Science & Engineering. 

Scientists have recently developed a potentially safer alternative by mimicking the hair's natural color molecule: melanin. The permanent hair dye ingredient p-phenylenediamine (PPD) has been associated, although rarely, with allergic reactions including facial swelling and rashes. Coloring hair with natural melanin would be an intuitive alternative to PPD. 
Polydopamine with iron ions transformed gray hairs into black and lasted through three wash cycles. Lighter shades could also be achieved with polydopamine by pairing it with copper and aluminum ions. Toxicity tests showed that mice treated with the colorant didn't have noticeable side effects, while those that received a PPD-based dye developed bald spots.

Synthetic yeast is about to become a reality

Scientists have constructed five more yeast chromosomes from scratch. The new work, reported online March 9 in Science, brings researchers closer to completely lab-built yeast. 

scientists might also be able to tinker with a synthetic yeast cell more efficiently than a natural one, allowing more precise engineering of everything from antiviral drugs to biofuels.

Boeke was part of a team that reported the first synthetic yeast chromosome in 2014. Now, several hundred scientists in five countries are working to make all 16 Saccharomyces cerevisiae yeast chromosomes and integrate them into living cells. With six chromosomes finished, Boeke hopes the remaining 10 will be built by the end of 2017.

Each synthetic chromosome is based on one of S. cerevisiae’s, but with tweaks for efficiency. Researchers cut out stretches of DNA that can jump around and cause mutations, as well as parts that code for the same information multiple times.  

When the researchers put chunks of synthetic DNA into yeast cells, the cells swapped out parts of their original DNA for the matching engineered snippets.

Yeast is a eukaryote — it stores its DNA in a nucleus, like human cells do. Eventually, this research could produce synthetic chromosomes for more complicated organisms.

Nutrition deficiency caused by climate change

Evidence builds for lessening of certain micronutrients, protein in plants

A dinner plate piled high with food from plants might not deliver the same nutrition toward the end of this century as it does today. Climate change could shrink the mineral and protein content of wheat, rice and other staple crops, mounting evidence suggests.

Selenium, a trace element essential for human health, already falls short in diets of one in seven people worldwide. Studies link low selenium with such troubles as weak immune systems and cognitive decline. And in severely selenium-starved spots in China, children’s bones don’t grow to normal size or shape. This vital element could become sparser in soils of major agricultural regions as the climate changes, an international research group announced online February 21 in Proceedings of the National Academy of Sciences.

Likewise, zinc and iron deficiencies could grow as micronutrients dwindle in major crops worldwide, Harvard University colleagues Samuel Myers and Peter Huybers and collaborators warned in a paper published online January 6 in the Annual Review of Public Health. Futuristic field experiments on wheat and other major crops predict that more people will slip into nutritional deficits late in this century because of dips in protein content, Myers reported February 16 at the Climate and Health Meeting held in Atlanta.
