Groundwater pumped to irrigate cannabis crops in California's Emerald Triangle can cause some streams that normally run year-round to dry up entirely during summer, say researchers from Simon Fraser University, the University ...
Medical Xpress / Microplastics cross placenta-like barrier and disrupt key pregnancy hormones in new cell model study
Tiny, near-invisible fragments of plastic shed from the products we use every day through sunlight and mechanical wear have been quietly working their way deep into the human body. Microplastics have already been found in ...
Medical Xpress / How the brain's electrical signatures shift as tinnitus becomes chronic
Ears are built to listen to sounds from the world around us, but for some people, the sound comes from within. Tinnitus causes people to hear ringing or other noises in one or both ears or in their heads, even when there ...
Phys.org / Decades-old theory for how insect societies evolve challenged
For more than 60 years, evolutionary biologists have debated whether a unique genetic system found in ants, bees and wasps helps explain one of nature's most remarkable innovations: eusociality, a form of social organization ...
Phys.org / Molecular orbitals imaged in 3D, opening path to femtosecond videos
One of the most famous and intriguing results of quantum mechanics is the finding that fundamental particles, such as electrons, cannot be pinned down to one single location. Instead, a particle is described by its "wavefunction," ...
Phys.org / Fossils from Wyoming's Smiley Draw deepen understanding of early primate evolution
A new study from the University of Kansas complicates the picture of primates living in North America some 55 million years ago during the Eocene, a warm period that allowed mammals to diversify quickly.
Phys.org / Women with narcissistic tendencies may struggle with forgiveness
Narcissism is associated with selfishness and other negative traits like a grandiose sense of self-importance, a constant need for admiration and a lack of empathy for others. So it may not be surprising that narcissists ...
Phys.org / First measurement of antineutrinos from spent nuclear fuel confirms emissions persist after reactor shutdown
Even when the lights go out and nuclear reactors are turned off, the story inside the reactor core still has a great deal to tell. Radioactive, long-lived fission products continue to decay for months or even years, producing ...
Medical Xpress / Analysis finds patient letters from eye clinics often too difficult to read
Letters to patients from ophthalmology services—the highest-volume outpatient specialty in U.K. health care—include too much complex language and medical terminology that patients are likely to find hard to understand, according ...

An erectile dysfunction drug that is also used to treat symptoms, such as sudden urgency and frequency, associated with an enlarged prostate in men may heighten the risk of glaucoma, a serious eye condition, a large comparative ...
Medical Xpress / Workers' pesticide exposure linked to 60–70% heightened motor neuron disease risk
Workplace exposure to pesticides (herbicides and insecticides) is linked to a 60%–70% heightened risk of the most common form of motor neuron disease—amyotrophic lateral sclerosis, or ALS for short—finds a synthesis of the ...
Phys.org / How a unique environment sets Australian chocolate apart
University of Queensland research has shown microbes could give Australian-grown chocolate an edge in the global market. Working with growers in Far North Queensland, scientists found the cocoa fermentation process may have ...
