Phys.org / How starfish control tube feet without a central nervous system or brain
Starfish, also known as sea stars, are equipped with an almost alien-like anatomy. Despite lacking a brain, blood, and central nervous system, these odd creatures still have locomotive abilities. The structure of their many ...
Phys.org / Asteroid that wiped out dinosaurs had limited impact on sharks and rays, study shows
A new study using advanced artificial intelligence (AI) has revealed that the asteroid strike that wiped out the dinosaurs 66 million years ago caused only a modest decline in shark and ray species. The findings, published ...
Medical Xpress / Cancer tumors may protect against Alzheimer's by cleaning out protein clumps
Cancer and Alzheimer's are two of the most common chronic diseases associated with aging. For years, doctors have known about a curious aspect of these two conditions: people who survive cancers are significantly less likely ...
Phys.org / Caribbean heat waves intensify over five decades, study finds
A new study led by climatologists at the University at Albany has found that extreme heat waves across the Caribbean are becoming significantly more frequent, longer and severe. This study examined extreme summer heat waves ...
Phys.org / Scientists develop high-performance Hg-based crystal for mid-far infrared birefringence
Mid- and far-infrared birefringent crystals are key functional materials for polarization control, laser technologies, and infrared photonics. However, existing materials generally suffer from limited infrared transparency, ...
Phys.org / A possible ice-cold Earth discovered in the archives of the retired Kepler Space Telescope
Scientists continue to mine data gathered by NASA's Kepler Space Telescope, retired in 2018, and continue to turn up surprises. A new paper reveals the latest: a possible rocky planet slightly larger than Earth, orbiting ...
Medical Xpress / Is everyday school life more stressful for teenagers than a global pandemic?
Lockdowns isolated teenagers from friends, disrupted their routines, and kept them at home with daily reports of bad news. So most people assume teenagers felt worse during COVID-19 lockdowns, but a Tokyo study shows the ...
Medical Xpress / Artificial lung system keeps patient alive without lungs until transplant
Humans can't live without lungs, but Ankit Bharat's patient did for 48 hours.
Phys.org / Flying gurnard grunts and flares fins to communicate, camera study confirms
Researchers have just published a study demonstrating that the flying gurnard (Dactylopterus volitans) emits sounds while simultaneously performing movements to communicate—a discovery that enriches our knowledge about ...
Phys.org / Male or female? How one frog gene 'hijacked' sex determination about 20 million years ago
Early in development, many animals pick a team—male or female—based on their genetics, and, with time, acquire the characteristics to match. New research from the Marine Biological Laboratory (MBL) explores how one species ...
Phys.org / 'Jerk' volcano early warning method uses single seismometer to detect magma movement
Forecasting volcanic eruptions in time to alert authorities and populations remains a major global challenge. In a study published in Nature Communications, researchers and engineers from the Institut de Physique du Globe ...
Phys.org / Shipping regulations to reduce pollution may have exacerbated Great Barrier Reef bleaching
Rising ocean temperatures have been implicated in mass coral bleaching events affecting the Great Barrier Reef (GBR). These events have been increasingly frequent, with major events occurring in 2016, 2017, 2020, 2022, 2024, ...
