Phys.org / A timescale for the origin and evolution of all of life on Earth
A new study led by scientists from the University of Bristol has used a combination of genomic and fossil data to explain the history of life on Earth, from its origin to the present day.
Tech Xplore / A new artificial neural network framework for gait based biometrics
Researchers at Imperial College London have recently devised a new biometric cryptosystem approach for securing wireless communications of wearable and implantable medical devices. Their framework, outlined in a study published ...
Phys.org / Light from ancient quasars helps confirm quantum entanglement
Last year, physicists at MIT, the University of Vienna, and elsewhere provided strong support for quantum entanglement, the seemingly far-out idea that two particles, no matter how distant from each other in space and time, ...
Phys.org / NASA's InSight passes halfway to Mars, instruments check in
NASA's InSight spacecraft, en route to a Nov. 26 landing on Mars, passed the halfway mark on Aug. 6. All of its instruments have been tested and are working well.
Phys.org / Militarization of police fails to enhance safety, may harm police reputation
This month marks the four-year anniversary of protests over the police killing of Michael Brown in Ferguson, Missouri, an incident met with a heavily armed police response that stoked widespread concern.
Phys.org / Carbon reserves in Central American soils still affected by ancient Mayan deforestation
Deforestation is suspected to have contributed to the mysterious collapse of Mayan civilization more than 1,000 years ago. A new study shows that the forest-clearing also decimated carbon reservoirs in the tropical soils ...
Medical Xpress / Core thinking error underlies belief in creationism, conspiracy theories: study
It's not uncommon to hear someone espouse the idea that "everything happens for a reason" or that something that happened was "meant to be." Now, researchers reporting in Current Biology on August 20 have found that this ...
Phys.org / Multi-purpose silicon chip created for quantum information processing
An international team of researchers led by the University of Bristol have demonstrated that light can be used to implement a multi-functional quantum processor.
Phys.org / California plain shows surprising winners and losers from prolonged drought
The Carrizo Plain National Monument is a little-known ecological hotspot in Southern California. Though small, it explodes in wildflowers each spring and is full of threatened or endangered species.
Medical Xpress / E-cigarettes can damage DNA
The popularity of electronic cigarettes continues to grow worldwide, as many people view them as a safer alternative to smoking. But the long-term effects of e-cigarette usage, commonly called "vaping," are unknown. Today, ...
Phys.org / Astronomers detect synchronous X-ray and radio mode switching of the pulsar PSR B0823+26
An international team of astronomers has detected synchronous X-ray and radio mode switching between radio-bright and a radio-quiet modes in the pulsar PSR B0823+26. The discovery marks the second time that such synchronous ...
Phys.org / Screen of human proteins reveals some with antimicrobial power
The human body produces many antimicrobial peptides that help the immune system fend off infection. Scientists hoping to harness these peptides as potential antibiotics have now discovered that other peptides in the human ...
