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.

If the virus that causes flu were an ice cream cone, then the yearly vaccine teaches the immune system to recognize just the scoop – chocolate one year, strawberry the next. As the virus changes each year, so too must the vaccine.

A new approach that teaches the body to recognize the cone portion of the virus – which stays the same year-to-year – could shake up that yearly vaccination ritual and protect people against pandemic flu like the one that killed 40 to 50 million people in 1918. The team working on this new approach, led by Stanford biochemist Peter Kim, has shown early signs that their technique works in lab animals. They warn that they still need to make their vaccine more specific and show it works in much larger studies before testing it in people.

“We think it could be very generalizable,” said Kim, who is the Virginia and D.K. Ludwig professor of biochemistry and the lead investigator of the infectious disease initiative at the Chan Zuckerberg Biohub. “It could be important for coming up with a universal flu vaccine that would protect against pandemic flu, as well as for HIV.”

The researchers conducted in-depth analyses of how touch signals are transferred and processed in neurons of various parts of the brain and the latest studies have been published in Cell Reports and Frontiers in Cellular Neuroscience. The experiments were conducted on anaesthetised rats.

“We immediately realised that our findings deviated strongly from the accepted view that different parts of the brain are responsible for different specific functions,” says Henrik Jörntell, one of the researchers behind the study.

A drug commonly used to treat multiple sclerosis may, after necessary modifications, one day be used to treat patients with epilepsy, researchers in Prof. Inna Slutsky’s lab at the Sackler Faculty of Medicine and Sagol School of Neuroscience at Tel Aviv University have discovered.

This is good news for patients with Dravet syndrome, one of the most dangerous forms of childhood epilepsy, for which there is currently no effective treatment.

According to a new study published on April 29 in Neuron, Tel Aviv University researchers uncovered a piece of a puzzle that has eluded scientists for 100 years of studying homeostasis: What is the mechanism that maintains activity set points in neural circuits?

Cognitive scientist Donald Hoffman asserts that not only do we invent our own personal views of reality, it’s an evolutionary necessity.

New data from the Hubble Space Telescope confirms that the universe is expanding nine percent more rapidly than theoretical calculations predicted.

Those original calculations were based on data from the early universe, so many scientists suspected that something sped up the works. But the new Hubble data suggests that the universe could be substantially younger than previously believed — perhaps by as much as a billion years, according to the Associated Press.

The smaller and lighter electronics get, the more ways they can be used. A team of researchers has come up with a compact radar system the size of a matchbox that could be deployed in drones, guidance systems for people with vision problems, and other gadgets where portability and low cost are important.

The recent clinical trial was only conducted on patients with lymphoma, but the researchers suggested their approach could be potentially used to treat other types of cancer — and that it could improve the efficacy of other immunotherapies, including checkpoint blockade.

“The in situ vaccine approach has broad implications for multiple types of cancer,” said Brody, the study’s lead author and the director of the Lymphoma Immunotherapy Program at The Tisch Cancer Institute at the Icahn School of Medicine at Mount Sinai. “This method could also increase the success of other immunotherapies such as checkpoint blockade.”
