An international team of researchers has, for the first time, demonstrated that by fixing a common glitch in photosynthesis, a crop’s yield could be improved by around 40 percent. The landmark study suggests optimizing a plant’s photosynthetic efficiency could significantly increase worldwide food productivity.
As if battered post-Christmas finances, a looming disorderly Brexit and the prospect of a fresh nuclear arms race were not enough to dampen spirits, astronomers have declared that a nearby galaxy will slam into the Milky Way and could knock our solar system far into the cosmic void.
The unfortunate discovery was made after scientists ran computer simulations on the movement of the Large Magellanic Cloud (LMC), one of the many satellite galaxies that orbits the Milky Way. Rather than circling at a safe distance, or breaking free of the Milky Way’s gravitational pull, the researchers found the LMC is destined to clatter into the galaxy we call home.
At the moment, the LMC is estimated to be about 163,000 light years from the Milky Way and speeding away at 250 miles per second. But simulations by astrophysicists at Durham University show that the LMC will eventually slow down and turn back towards us, ultimately smashing into the Milky Way in about 2.5 billion years’ time.

The growing understanding of the link between the gut and brain inflammation is perhaps one of the most exciting new avenues in modern medical research. An incredible new study from researchers at the University of Toronto and UC San Francisco has provided a novel insight into the gut-brain connection, revealing the intestine may be the source of immune cells found to reduce brain inflammation in multiple sclerosis (MS) sufferers.
Scientists have fixed a natural flaw in photosynthesis, and as a result have boosted plant productivity by an incredible 40 percent compared to wild relatives.
Photosynthesis is the chemical reaction that lets plants turn sunlight and carbon dioxide into food, and this new hack could result in enough calories to help feed another 200 million people on our planet, from the same volume of crops.
As of now, the fix has only been applied to tobacco plants, so we’re a long way off using this to boost our food supply. But it’s an incredibly promising first step.

It’s true that this was a horrible year for many of the tech industry’s biggest companies. Amazon held a nationwide beauty pageant for its new headquarters, raising hopes that the company would help transform a struggling city, then picked the two places that needed it the least. Executives from Facebook, Google and Twitter got hauled before Congress to apologize for * gestures wildly in all directions*. One of Uber’s self-driving cars killed someone. And then there was Elon Musk.
But the tech sector is more than its giants.
Last year, I handed out “good tech” awards to a handful of companies, nonprofit organizations and people who used technology to help others in real, tangible ways. The goal was to shine a spotlight on a few less-heralded projects that may not get front-page headlines or billions of dollars in funding, but are actually trying to fulfill the tech industry’s stated goal of improving the world.
Popular spit-in-a-tube genetics-testing companies like Ancestry and 23andMe can — and frequently do — sell your data to drugmakers. But on Wednesday, one of those partnerships became much more explicit, when the pharmaceutical giant GlaxoSmithKline announced it was acquiring a $300 million stake in 23andMe.
As part of a four-year deal between the two companies, GlaxoSmithKline will comb 23andMe’s genetic data to look for new drugs to develop, also referred to as drug targets. It will also use the genetic data to inform how patients are selected for clinical trials.
If that news has you thinking about how your own genetic material is being used for research, know that though the DNA you submit to these services is ostensibly anonymized, leaks can happen, and privacy advocates say that such incidents could allow your data to find its way elsewhere, perhaps without your knowledge.
