Can forgiving someone today leave you with an improved sense of well-being a year from now? A new study of residents of 22 countries says yes. The caveat, though, is that the size of the impact varies by nation, as does its ...
Phys.org / New AI method flags fluid flow tipping points before simulations break down
David J. Silvester, a mathematics professor at the University of Manchester, has developed a novel machine-learning method to detect sudden changes in fluid behavior, improving speed and the cost of identifying these instabilities ...
Medical Xpress / CBD found to reverse brain damage in mouse model of Alzheimer's disease
Alzheimer's disease (AD) is a neurodegenerative disorder characterized by progressive memory loss, cognitive decline, and behavioral changes. The deficits linked to AD are known to result from the abnormal accumulation of ...
Phys.org / Keeping up with the phages: How V. cholerae neighbors swap defenses against viruses
Like most bacteria, Vibrio cholerae lives under constant attack from viruses. To survive, bacteria equip themselves with antiviral immune systems. Previous work has shown that V. cholerae carries a large genetic element called ...
Phys.org / Houston, we have a problem ... with the toilet
After a successful trip around the moon, everything has been going smoothly on the Orion spacecraft's journey back to Earth—except for the $23 million toilet, which has gotten clogged.
Phys.org / Rock bonding changes understanding of earthquake mechanics
When tectonic plates move, they rarely do so smoothly. Sometimes they slide almost imperceptibly; at other times, stress is suddenly released—resulting in an earthquake. What exactly governs this behavior remains one of the ...
Phys.org / The oldest breath: A 300-million-year-old mummy reveals the origins of how amniotes breathe
Every breath you take is an ancient inheritance. The rise and fall of your chest, the intercostal muscles pulling your ribs outward, the rush of air into your lungs—this mechanism is so familiar it barely registers as remarkable. ...

By analyzing DNA of ancient skeletons at a Neolithic burial site near Paris, an international team of researchers has uncovered evidence of a dramatic population replacement 5,000 years ago. The findings indicate that the ...
Phys.org / Ancient Romans were obsessed with a plant said to be a contraception and an aphrodisiac. Then one day, it went extinct
Roman leader Julius Caesar is said to have kept a stock of it in the treasury. Ancient writer Pliny the Elder says Rome's Emperor Nero owned the last stalk of it. And some have suggested rampant extramarital sex in elite ...
Medical Xpress / Fat-producing enzyme may amplify damage in Parkinson's disease
A fat-producing enzyme in brain cells may play a key role in driving damage in Parkinson's disease and could offer a new target for treatment, scientists at Nanyang Technological University, Singapore (NTU Singapore) have ...
Phys.org / Examining embryo model ethics beyond box-checking
In science, ethical guidelines ensure that research takes place in a way that respects public trust and is conducted responsibly. Traditional ethics approval procedures work well for projects following established practices, ...
Phys.org / Ant larvae control parental care by using odor signals
In the clonal raider ant (Ooceraea biroi), workers in a colony alternate between caring for larvae and laying eggs in a coordinated cycle. Researchers at the Max Planck Institute for Chemical Ecology in Jena have discovered ...
