Medical Xpress / People with premenstrual dysphoric disorder have higher rates of suicidal thinking, planning and attempts
People with premenstrual dysphoric disorder—a more serious form of premenstrual syndrome, commonly known as PMS—are more likely to experience suicidal thoughts and behaviors than people without it.
Phys.org / Quantum geometry provides theoretical limits on measurable properties of solids
Two RIKEN physicists have established new theoretical limits for experimentally measurable quantities by viewing solids through a lens of quantum geometry. Their results shed light both on the physics of solids and on quantum ...
Medical Xpress / ALS is driven by a domino‑like chain reaction that begins in nerve cells, research reveals
Patients with amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, live an average of only three years after symptoms begin, though some can survive closer to 10 years. What drives these differences in survival has ...
Medical Xpress / The rules neurons follow to make sense of what we see
Even in the primary visual cortex, a brain region named for its specialized role in processing basic features of what the eyes see, not every neuron ends up answering the call to process properties of visual input. Maybe ...
Medical Xpress / A look at major Ebola outbreaks and when the disease was first identified
African health officials say there is a new Ebola outbreak in the Central African country of Congo, with at least 246 suspected cases and 65 deaths.
Medical Xpress / Dinner at the door: Convenient healthy meals may ease depression symptoms
Making healthy meals more convenient through meal delivery services could improve depressive symptoms by removing some of the daily burdens that often accompany depression, according to a new University of Michigan study.
Phys.org / Sunlight-powered generation of correlated photon pairs
Pairs of correlated or entangled photons are a foundational resource in quantum optics. They are most commonly produced through spontaneous parametric down-conversion (SPDC), a nonlinear optical process that typically relies ...
Phys.org / These computer voices sound human enough to mislead, but one layer of speech still breaks the illusion
We are surrounded by computer-generated voices these days, from navigation systems and voice assistants to automated announcements. But how human do these voices actually sound? A recent study by the Max Planck Institute ...
Medical Xpress / The liver's immune cells might be the key to curing hepatitis B
Fifteen years ago, doctors in Europe noticed a remarkable thing happening in people with chronic hepatitis B infections. When patients went off their medications, the virus started to come back—and then some of the patients ...
Phys.org / Picturing Earth in a new light
Maps can show more than just where things are—they can also show how things change. New maps of artificial light reveal a planet that has been reshaping its nights through patterns of brightening and dimming.
Phys.org / Identity traits sharply narrow who becomes friends or marries, model reveals
Our personal identity is composed of many dimensions, such as age, gender, ethnic background, or socioeconomic status. A research team led by Fariba Karimi from the Institute of Human-Centered Computing at Graz University ...
Dialog / Optical meta‑conveyors enable programmable nanomanipulation along arbitrary open paths
The task of gently transporting a microscopic particle from one point to another along a winding path, and then bringing it back using nothing more than a single, compact chip is a challenge we set out to address in our new ...
