Phys.org / A better way to search for extraterrestrial intelligence
When you're looking for signs of extraterrestrial intelligence, it helps to know what you're looking for and to go about it in the most efficient way. But work so far has generally not done so, writes Benjamin Zuckerman, ...
Phys.org / How photosynthetic bacteria pass light along: Two major energy pathways identified
RIKEN researchers have found out how light energy harvested by pigments besides chlorophyll is transferred to the molecular site where photosynthesis occurs in cyanobacteria. The work is published in the journal Plant and ...
Phys.org / The way a cell fails to divide after copying its DNA can determine its fate
Cell division is one of the most fundamental and complex processes underpinning life. In human cells, thousands of molecules coordinate with one another in highly precise steps, all within a fraction of a second. But things ...
Medical Xpress / Reverse engineering ketamine's effects may lead to new antidepressants
Weill Cornell Medicine investigators have "reverse engineered" ketamine's antidepressant effects to identify potential new strategies for treating depression. While there are many effective treatments available for depression, ...
Phys.org / Azide-to-diazo reaction unlocks safer path to versatile nitrogen-rich compounds
In the world of organic chemistry, nitrogen-containing organic compounds are ubiquitous, forming the backbone of pharmaceuticals, agrochemicals, dyes, and functional materials. To build these important molecules, chemists ...
Medical Xpress / Early brain regions play greater role in decision-making, challenging traditional neuroscience
New insight into decision-making pathways in the brain may impact the way engineers think about artificial intelligence, according to new research from The Grainger College of Engineering at the University of Illinois Urbana-Champaign. ...
Phys.org / AI tackles one of math's most brutal problems: Inverse PDEs
Penn Engineers have developed a new way to use AI to solve inverse partial differential equations (PDEs), a particularly challenging class of mathematical problems with broad implications for understanding the natural world.
Phys.org / Bigger, faster, but still outfoxed: How prey escape predators
Predators are typically larger, faster, and more powerful than the animals they hunt. Yet in nature, most attacks fail. A new study published in the Proceedings of the National Academy of Sciences, by researchers from the ...
Medical Xpress / Skull microchannels reveal hidden route for brain immune defense
A study led by Rafael Gallareto-Sande, a predoctoral researcher at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), provides new insights into a network of tiny blood vessels within the cranial bones ...
Medical Xpress / Battery-free skin-conformal wearable system can measure electrocardiogram signals
A research team led by Prof. Jerald Yoo from the Department of Electrical and Computer Engineering at Seoul National University (SNU) has developed a skin-conformal wearable health care system, "SkinECG," capable of measuring ...
Phys.org / Physicists have measured 'negative time' in the lab
As Homer tells us, Odysseus made an epic journey, against the odds, from Troy to his home in Ithaca. He visited many lands, but mostly dwelt with the nymph Calypso on her island. We can imagine that his wife, Penelope, would ...
Phys.org / Slower access, faster chemistry: Nanoreactor design improves catalysis by balancing molecular flow
A new study by a team at Tohoku University, published in Chemical Engineering Journal, has shown that more isn't always better when it comes to nanoscale chemical reactions. One might think that giving reactants completely ...
