The world’s oceans soak up about a quarter of the carbon dioxide that humans pump into the air each year—a powerful brake on the greenhouse effect. In addition to purely physical and chemical processes, a large part of this is taken up by photosynthetic plankton as they incorporate carbon into their bodies. When plankton die, they sink, taking the carbon with them. Some part of this organic rain will end up locked into the deep ocean, insulated from the atmosphere for centuries or more. But what the ocean takes, the ocean also gives back. Before many of the remains get very far, they are consumed by aerobic bacteria. And, just like us, those bacteria respire by taking in oxygen and expelling carbon dioxide. Much of that regenerated CO₂ thus ends up back in the air.

A new study suggests that CO₂ regeneration may become faster in many regions of the world as the oceans warm with changing climate. This, in turn, may reduce the deep oceans’ ability to keep carbon locked up. The study shows that in many cases, bacteria are consuming more plankton at shallower depths than previously believed, and that the conditions under which they do this will spread as water temperatures rise. The study was published this week in the journal Proceedings of the National Academy of Sciences.

“The results are telling us that warming will cause faster recycling of carbon in many areas, and that means less carbon will reach the deep ocean and get stored there,” said study coauthor Robert Anderson, an oceanographer at Columbia University’s Lamont-Doherty Earth Observatory.

To understand them well, look to the past.

The spoken word is a powerful tool, but not all of us have the ability to use it, either due to biology or circumstances. In such cases, technology can bridge the gap — and now that gap is looking shorter than ever, with a new algorithm that turns messages meant for your muscles into legible sounds.

Converting the complex mix of information sent from the brain to the orchestra of body parts required to transform a puff of air into meaningful sound is by no means a simple feat.

Two years ago a team of scientists visited Costa Rica’s subduction zone, where the ocean floor sinks beneath the continent and volcanoes tower above the surface. They wanted to find out if microbes can affect the cycle of carbon moving from Earth’s surface into the deep interior. According to their new study in Nature, the answer is affirmatively—yes they can.

This groundbreaking study shows that microbes consume and—crucially—help trap a small amount of sinking carbon in this zone. This finding has important implications for understanding Earth’s fundamental processes and for revealing how nature can potentially help mitigate climate change.

Maxwell’s demon is a machine proposed by James Clerk Maxwell in 1897. The hypothetical machine would use thermal fluctuations to obtain energy, apparently violating the second principle of thermodynamics. Now, researchers at the University of Barcelona have presented the first theoretical and experimental solution of a continuous version of Maxwell’s demon in a single molecule system. The results, published in the journal Nature Physics, have applications in other fields, such as biological and quantum systems.

“Despite its simplicity and the large amount of work in the field, this new variant of the classical Maxwell demon has remained unexplored until now,” notes F\xE8lix Ritort, professor from the Department of Fundamental Physics of the UB. “In this study, we introduced a system able to extract large amounts of work arbitrarily per cycle through repeated measurements of the state of a system.”

Humanity could be on the verge of an unprecedented merging of human biology with advanced technology, fusing our thoughts and knowledge directly with the cloud in real-time – and this incredible turning point may be just decades away, scientists say.

In a new research paper exploring what they call the ‘human brain/cloud interface’, scientists explain the technological underpinnings of what such a future system might be, and also address the barriers we’ll need to address before this sci-fi dream becomes reality.

At its core, the brain/cloud interface (B/CI) is likely to be made possible by imminent advances in the field of nanorobotics, proposes the team led by senior author and nanotechnology researcher Robert Freitas Jr from the Institute for Molecular Manufacturing in California.

Alexandre Zanghellini can’t help but think about what makes up the world around him. Sitting in a conference room, Zanghellini considered the paint on the walls, the table, the window shades, the plastic chairs. It’s all oil.

“The entire world is made from oil. We just don’t realize it,” he said.

Zanghellini’s job, as the CEO of Seattle-based synthetic biology company Arzeda, is to reconsider how we make the basic molecules that go into anything and everything in the human world. And he has a bias for processes that use living organisms. “The tools of biology, proteins, are better at doing chemistry than chemists,” he said.

In a new study published in the journal Human Biology, archaeologists from the Tel Aviv University reveal the molecular similarities between Neanderthals and woolly mammoths by studying three case studies.

Scientists discover that two completely different species can evolve and develop the same genetic characteristics. In a landmark study, Neanderthals and woolly mammoths are found to be very similar to each other.
