3-D images reveal how infants' heads change shape during birth

Using Magnetic Resonance Imaging (MRI), scientists have captured 3-D images that show how infants' brains and skulls change shape as they move through the birth canal just before delivery. Olivier Ami of Auvergne University in Clermont Ferrand, France, and colleagues present these findings in the open access journal PLOS ONE on May 15, 2019.

New drug could help treat neonatal seizures

A new drug that inhibits neonatal seizures in rodent models could open up new avenues for the treatment of epilepsy in human newborns. Researchers have identified that gluconate—a small organic compound found in fruit and honey—acts as an anticonvulsant, inhibiting seizures by targeting the activity of channels that control the flow of chloride ions in and out of neonatal neurons. A paper describing the research, from an international team of scientists led by Penn State researchers, appears May 15, 2019 in the journal Molecular Brain.

Framework improves 'continual learning' for artificial intelligence

Researchers have developed a new framework for deep neural networks that allows artificial intelligence (AI) systems to better learn new tasks while "forgetting" less of what it has learned regarding previous tasks. The researchers have also demonstrated that using the framework to learn a new task can make the AI better at performing previous tasks, a phenomenon called backward transfer.

New AI sees like a human, filling in the blanks

Computer scientists at The University of Texas at Austin have taught an artificial intelligence agent how to do something that usually only humans can do—take a few quick glimpses around and infer its whole environment, a skill necessary for the development of effective search-and-rescue robots that one day can improve the effectiveness of dangerous missions. The team, led by professor Kristen Grauman, Ph.D. candidate Santhosh Ramakrishnan and former Ph.D. candidate Dinesh Jayaraman (now at the University of California, Berkeley) published their results today in the journal Science Robotics.

Ancient fish ponds in the Bolivian savanna supported human settlement

A network of fish ponds supported a permanent human settlement in the seasonal drylands of Bolivia more than one thousand years ago, according to a new study published May 15, 2019 in the open-access journal PLOS ONE by Gabriela Prestes-Carneiro of Federal University of Western Para, Brazil, and colleagues. The study is the first to document the full range of fish species likely kept in these constructed ponds, and provides new insights into how humans modified the savannah environment to cope with the months-long droughts that characterize this region of the Amazon Basin.

Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells

Solar cells made of perovskite hold much promise for the future of solar energy. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly. The solar cells retain 90 percent of their efficiency after 1000 hours operation at various extreme testing conditions. The findings are published today in the leading scientific journal Nature Energy.

Study identifies how cancer drug inhibits DNA repair in cancer cells

According to researchers at Yale Cancer Center, a cancer drug thought to be of limited use possesses a superpower of sorts: It is able to stop certain cancer cells from repairing their DNA in order to survive. The study, published today in the journal Science Translational Medicine, suggests that combining this drug, cediranib, with other agents could potentially deliver a lethal blow in cancer that uses a specific pathway—or process—to create DNA repair cells.

Researchers map symbiotic relationships between trees and microbes worldwide

In and around the tangled roots of the forest floor, fungi and bacteria grow with trees, exchanging nutrients for carbon in a vast, global marketplace. A new effort to map the most abundant of these symbiotic relationships—involving more than 1.1 million forest sites and 28,000 tree species—has revealed factors that determine where different types of symbionts will flourish. The work could help scientists understand how symbiotic partnerships structure the world's forests and how they could be affected by a warming climate.

A nerve cell serves as a "single" for studies

Nerve cells derived from human stem cells often serve as the basis for research into brain diseases. However, these cells differ considerably in their quality and produce varying results. Scientists around the world are therefore looking for simple cell models that lead to consistent results when an experiment is repeated. Research teams from the University of Bonn, the Vrije Universiteit Amsterdam and the Max Planck Institute for Experimental Medicine in Göttingen describe a model derived from stem cells that consists of only one human nerve cell. It was obtained from pluripotent stem cells through a fast forward programming method and provides highly standardized conditions for investigating nerve cell functions. The two studies have now been published in the international journal Cell Reports.
