Medical Xpress / Study reveals sharp vision comes from single cone cells in the fovea
The human eye can see with exceptional detail, allowing people to read fine print, recognize faces across the room, and take in the features in nature. Scientists have long debated how this sharp vision works at the cellular ...
Medical Xpress / Intermittent fasting positively affects female hormones in PCOS, study finds
Polycystic ovary syndrome, or PCOS, affects as many as 18% of all childbearing-age women. The condition occurs when a woman's body produces too much of a group of hormones called androgens, chiefly testosterone. Menstrual ...
Phys.org / New study pinpoints climate conditions for restoring the endangered butternut tree
The butternut tree, a close relative of black walnut prized for its pale wood and wildlife value, is on the brink of disappearing from North American forests. A new study from Virginia Tech offers hope that the species could ...
Phys.org / Do narcissists ruin relationships over time? A six-year study suggests a more complex pattern
New research from Michigan State University challenges the popular assumption that narcissists gradually damage their relationships over time.
Medical Xpress / The challenge of delivering evidence‑based medicine in children's care
It is easy to overlook the fact that over 90% of medical treatments are not backed by strong evidence. People can find it frustrating—even infuriating—when a review concludes that the evidence for a treatment is too weak ...
Phys.org / New insights into hornification could strengthen the future of paper production
When paper dries and is subsequently rewetted, its properties change permanently. This phenomenon is known as hornification. New research now shows that the process is more complex than previously assumed, and that temperature, ...
Tech Xplore / Helping resolve quantum computers' memory problem
A major problem with quantum computers is memory, as the information they contain can be quickly lost. Quantum computers are not yet fully reliable—they are far too unstable. However, all around the world, people are trying ...
Phys.org / Artemis astronauts more than halfway to Moon, putting Earth in rearview
The Artemis 2 astronauts have passed the halfway point between Earth and the moon on Saturday as they sped toward a planned lunar flyby, with NASA releasing initial images of Earth taken from inside the Orion spacecraft.
Phys.org / Artemis II's moonbound astronauts capture Earth's brilliant blue beauty as they leave it behind
The Artemis II astronauts have captured our blue planet's brilliant beauty as they zoom ever closer to the moon.
Phys.org / Iridium's hidden surface chemistry may change how hydrogen and chlorine are made
Iridium is a key component in many electrochemical technologies used for chemical transformations. These include producing hydrogen fuel from water, manufacturing chlorine from seawater for use as a disinfectant and extracting ...
Tech Xplore / How a 'perfectly symmetrical' 2D perovskite could boost tandem solar cells
Rice University scientists and collaborators have created a new type of two-dimensional (2D) semiconductor that comes closer than ever to a "perfect" crystal. The findings, reported in the journal Nature Synthesis, could ...
Phys.org / Our modern vision evolved from an ancient one‑eyed worm creature
It's easy to take our eyes for granted. But our recent research shows they took an incredible evolutionary journey to reach their current familiar form.
