Bacteria can use magnetic particles to create ''natural battery''
PhysOrg, 10 hours ago
New research shows bacteria can use tiny magnetic particles to effectively create a ''natural battery.'' According to study published in journal Science on 27 March, the bacteria can load electrons onto and discharge electrons from microscopic particles of magnetite. This discovery holds out the pot...
Galaxy clusters collide-dark matter still a mystery
PhysOrg, 10 hours ago
When galaxy clusters collide, their dark matters pass through each other, with very little interaction. Deepening the mystery, a study by scientists at EPFL and the University of Edinburgh challenges the idea that dark matter is composed of particles.
Intergenerational transmission of abuse and neglect more complicated than previously believed
PhysOrg, 10 hours ago
A study led by Cathy Spatz Widom, Distinguished Professor of Psychology at John Jay College, found that offspring of parents with histories of child abuse and neglect are themselves at risk for childhood neglect and sexual abuse but not physical abuse. Titled "Intergenerational Transmission of Child...
Antarctic ice shelves rapidly thinning
PhysOrg, 10 hours ago
A new study led by Scripps Institution of Oceanography at UC San Diego researchers has revealed that the thickness of Antarctica''s floating ice shelves has recently decreased by as much as 18 percent in certain areas over nearly two decades, providing new insights on how the Antarctic ice sheet is ...
Bats obey ''traffic rules'' when trawling for food
PhysOrg, 10 hours ago
Foraging bats obey their own set of ''traffic rules'', chasing, turning and avoiding collisions at high speed, new research from the University of Bristol, UK has found.
To survive, a parasite mixes and matches its disguises, study suggests
PhysOrg, 10 hours ago
Orchestrated costume changes make it possible for certain nasty microbes to outsmart the immune system, which would otherwise recognize them by the telltale proteins they wear. By taking the first detailed look at how one such parasite periodically assumes a new protein disguise during a long-term i...
Theory of the strong interaction verified
PhysOrg, 10 hours ago
The fact that the neutron is slightly more massive than the proton is the reason why atomic nuclei have exactly those properties that make our world and ultimately our existence possible. Eighty years after the discovery of the neutron, a team of physicists from France, Germany, and Hungary headed b...
Special ops troops using flawed intel software
PhysOrg, 10 hours ago
Special operations troops heading to war zones are asking for commercial intelligence analysis software they say will help their missions. But their requests are languishing, and they are being ordered to use a flawed, in-house system preferred by the Pentagon, according to government records and in...
Engineers develop new methods to speed up simulations in computational grand challenge
PhysOrg, 10 hours ago
Engineers at the University of California, San Diego, have developed a new family of methods to significantly increase the speed of time-resolved numerical simulations in computational grand challenge problems. Such problems often arise from the high-resolution approximation of the partial different...
Using magnetic fields to understand high-temperature superconductivity
PhysOrg, 10 hours ago
Taking our understanding of quantum matter to new levels, scientists at Los Alamos National Laboratory are exposing high-temperature superconductors to very high magnetic fields, changing the temperature at which the materials become perfectly conducting and revealing unique properties of these subs...
