Researchers find a way to reverse antibiotic resistance in Mycobacterium tuberculosis

A team of researchers from Sweden, France, Belgium and Switzerland has found a way to reverse resistance to an antibiotic drug used to treat tuberculosis. In their paper published in the journal Science, the team describes how they screened compounds that activated different pathways to activate ethionaide, a compound used to treat tuberculosis.


Programming human cells to follow sets of logical instructions

A team of researchers at Boston University has developed a new way to engineer mammalian cells that allows for programming them to behave in desired ways. In their paper published in the journal Nature Biotechnology, the team describes their technique and where they believe such technology is heading.


Largest ever brain cancer study provides key insight into one of its deadliest forms

As far as cancers go, one of the worst is a type of brain cancer called glioma - the disease has a five-year survival rate of just 5 percent, and no reliable method for early detection.



A giant study that pooled genetic data from tens of thousands of people could change that, finding more than a dozen new mutations for physicians to hunt for in an effort to identify who is at risk of developing glioma.


The Arctic is turning green at an alarming rate, and scientists finally know why

Arctic sea ice is turning progressively greener, and for years now, scientists couldn't for the life of them figure out what was going on. 



They knew the green had to come from blooms of microscopic marine plants called phytoplankton growing under the sea ice, but that didn't make sense - phytoplankton need light to photosynthesise, and it should have been far too dark for them to survive down there, let alone thrive.


All-Corn Diet Turns Hamsters Into Cannibals Who Eat Their Young

Researchers in France have discovered that a monotonous diet of corn causes hamsters to exhibit some unusual behavior—cannibalism. 



new paper outlines the efforts of scientists at the University of Strasbourg to determine why the European hamster (Cricetus cricetus) has been dying off at an alarming rate.


What It Will Take to Become an Interstellar Civilization

Last month, a bunch of rocket scientists, microbiologists and entrepreneurs gathered in Houston’s George R. Brown Convention Center to discuss—in level and serious tones—how to become a spacefaring civilization. The meeting is called the 100-Year Starship symposium, and it’s brought brains together once a year since 2011 to figure out what we need to do now if we want to have an interstellar spacerocket a century from now.


India's capital just banned all forms of disposable plastic

India’s capital city, Delhi, has introduced a ban on disposable plastic.



Cutlery, bags, cups and other forms of single-use plastic were prohibited by the National Green Tribunal (NGT).



There is particular concern in the country about the amount of plastic waste it produces. According to the Times of India, it is responsible for an astonishing 60 percent of the plastic that is dumped in the...

HOW TO PROVE THAT LIGHT CAN BE CONVERTED INTO MATTER

In 1934, two American physicists theorized that if one could make two photons collide, the collision would produce two positron-electron pairs—and thus convert light into matter. If proven in a lab, the process would be a pure demonstration of Einstein's theory of relativity, E=mc2, which states that the mass of an object is also a measure of its stored energy. At the time the scientists—Gregory Breit and John A. Wheeler, physicists at New York University—devised their hypothesis, there were no scientific tools available to demonstrate it, so the pair...

How photonics can reshape the spectrum of light, and rehabilitate Edison's light bulb along the way

Traditional light bulbs, thought to be well on their way to oblivion, may receive a reprieve thanks to a technological breakthrough. Incandescent lighting and its warm, familiar glow is well over a century old yet survives virtually unchanged in homes around the world. That is changing fast, however, as regulations aimed at improving energy efficiency are phasing out the old bulbs in favor of more efficient compact fluorescent bulbs (CFLs) and newer light-emitting diode bulbs (LEDs).
