Phys.org / 'Heel-strike' may have allowed early humans to walk farther—at the cost of high-impact forces
The average person takes thousands of steps each day, instinctively walking heel-to-toe. Although they hardly register them, those consistent heel-first strides are more distinctive to humans than previously thought and allowed ...
Phys.org / How we manage and engage with horses may shape their personality
A new study reveals that horse personality is not only a matter of genetics, age or breed but also systematically linked to how horses are housed, ridden and cared for, and to the quality of the relationship they share with ...
Phys.org / Unaccounted climate feedback loops may amplify warming by 20–30% this century, but cutting emissions will reduce risks
New research shows that warming-induced emissions—greenhouse gas emissions from natural sources driven by rising temperatures—could amplify global warming by approximately 20%–30% and add an estimated 0.2°C–0.4°C of warming ...
Phys.org / Super-resolution imaging reveals details inside living cells
A new fluorescence microscopy technique that generates super-resolution images from a single camera exposure could help researchers study rapid movements within cells that are difficult to capture with existing methods.
Medical Xpress / Psychedelics and anesthetics create mirror image patterns in the brain
For something so familiar to human experience, consciousness is still a mystery. Each day, people cycle through wakefulness and sleep, from a higher level of consciousness to a lower one. What's more, some people alter their ...
Phys.org / Decades-old DNA mystery solved after strands are captured zipping together for the first time
Researchers have captured the moment two DNA molecules zip together, overcoming their identical negative charges to pair up and revealing a mechanism that has puzzled scientists for more than 20 years. Using high-powered ...
Phys.org / Psychologist wins Ig Nobel for proving rich drivers are the worst
Paul K. Piff, UC Irvine associate professor of psychology, has officially been recognized for what millions of frustrated commuters have long suspected: The fancier the car, the worse the driver.
Medical Xpress / Two newly implicated genes reveal why some patients' cilia cannot clear mucus in the lungs
Hair-like appendages called motile cilia beat in synchrony on cells in many parts of the body to keep fluids and particles moving, such as clearing mucus in the lungs so it can be coughed out.
Medical Xpress / Chemotherapy alters 'Darwinian battleground' in our bodies
Cancer treatments, including chemotherapy and radiation therapy, give a growth advantage to cells with particular genetic changes in healthy tissue, new research finds.
Phys.org / Pumping antibiotics out: A new route to bacterial drug resistance
Bacteria can survive antibiotics in several ways, including by pumping the drugs out of their cells before they can take effect. Researchers at the University of Osaka have discovered a previously unknown mechanism that allows ...
Phys.org / 'Peculiar' new species of Jurassic squid found in Wyoming
A "peculiar" new species of Jurassic squid-like animal has been unearthed in Wyoming, U.S., following the discovery of two exceptionally rare fossils dating to around 160 million years ago.
Medical Xpress / Trial supports MRI surveillance over preventive brain radiation in small-cell lung cancer
Results from the international phase 3 SWOG S1827 MAVERICK trial show that brain MRI surveillance alone improved cognitive failure-free survival compared with MRI surveillance plus prophylactic cranial irradiation (PCI) in ...
