An international team of astronomers, including researchers from the Department of Physics and the Hong Kong Institute for Astronomy and Astrophysics (HKIAA) at The University of Hong Kong (HKU), has discovered a previously hidden phase of high-energy activity following the
As Ted Schuur stepped along the edges of Smith Lake, a bubble surfaced from the muck underfoot. And then another. They're bubbles of methane, a potent heat-trapping gas made from decomposing plants and animals that had once been stuck in Alaska's frigid permafrost. But that
Saturn's icy moon Enceladus hides a global ocean beneath its frozen surface. From fractures near its south pole, material from this ocean is ejected into space as a plume of water vapor and ice particles. These particles offer scientists a rare opportunity to investigate an

The U.S. prison population is declining at an accelerating rate, and prison admission rates are predicted to fall an additional 50% within the next two decades, according to new research from University at Albany professor Shawn Bushway.
Deep in Peru's Acarí Valley lie the ruins of Tambo Viejo, an Inka provincial center where excavations have uncovered tasseled sacrificial llamas and brightly adorned guinea pigs. But save for a few seeds and some stored leaves, evidence of how the Inka used one of their most
A meteor crater buried beneath Oklahoma has turned out to be nearly 100 million years younger than scientists thought. Zircon crystals show the Ames impact occurred about 370 million years ago, meaning it was not part of the mysterious Ordovician bombardment once linked to a
Tiny magnetic fields created shortly after the Big Bang may help explain the long-running disagreement over how fast the universe is expanding. Detailed simulations show that these primordial fields could have changed the formation of hydrogen in the early universe, affecting
When light travels through a strongly scattering material, such as biological tissue or other disordered opaque media, it follows many different paths and produces a seemingly random speckle pattern. Wavefront shaping makes it possible to control this complex interference and
A 30-year forestry experiment in Australia found that heavily thinned mountain ash forests grew unusually large trees while recovering enough carbon to match or exceed untouched areas. The results suggest carefully managed thinning could support timber production, wildlife
A UCLA study links faster brain aging to specific gut bacteria and chemical byproducts, with older-looking brains also associated with poorer memory, focus, and mood. The findings suggest that biological signs of brain aging may appear decades before obvious symptoms and could
Working from before dawn until midnight, farmers Nikoletta Pajsan Nagy and Laszlo Pajsan fought Europe's driest summer ever to save their red pepper harvest in Hungary.
A new light-activated material can efficiently produce hydrogen from water without requiring an additional expensive metal catalyst. Researchers say its unusual sulfur-based chemistry could point toward cheaper and more practical ways to turn sunlight into clean fuel.
The picturesque Lac des Brenets between France and Switzerland has dried up after a record-breaking hot summer, leaving locals crying out for help to save the lake.
High-dose vitamin B3 is showing intriguing early promise as an addition to standard glioblastoma treatment, with 82% of patients in a small trial remaining progression-free after six months. Researchers believe niacin may help revive immune cells suppressed by the cancer, but
Attachment is the term psychologists use for the most significant relationships that hold people’s lives together
A vitamin D analog may help break down pancreatic cancer’s protective defenses, potentially making tumors more vulnerable to chemotherapy and immune attack. A small clinical trial found encouraging responses, especially in patients whose tumors had high levels of the vitamin D
A two-year randomized clinical trial involving 493 adults with overweight or obesity found that diet soft drinks were essentially as effective as water for long-term weight loss and weight maintenance. Participants drinking beverages sweetened with aspartame, acesulfame-K, or
Americans are crazy about sports. But whether that passion requires taxpayers to subsidize new facilities every time leagues and franchises ask for them needs rigorous scrutiny.
When everyone in a meeting voices the same opinion, an organization can miss important warning signs and new ideas. A research team from KAIST suggests that when members feel securely accepted within their group, they can express dissenting opinions in greater detail and more
The Pacific Ocean is warming unusually quickly, and this year's El Niño has already surpassed previous records. Forecasters expect it to strengthen even further before approaching its usual peak around December.
Cutting greenhouse gas emissions now may limit how much ice Antarctica loses this century and reduce the sea-level rise facing coastal communities, according to findings from a new study.
A "hidden variable" that can determine the success or failure of a chemical reaction has been found in the immediate vicinity of electrodes.
Violence in the home can range from intimidation to physical abuse. When it occurs there, we refer to it as domestic violence. Every year, more than 1 million people in the Netherlands age 16 and older experience domestic violence. This type of violence is often perpetrated by
When I explain topology to students, I start with a knot in a rope. You can stretch it, twist it or shake it, but the knot stays until you cut the rope. Physicists have found that some materials and devices carry similar "knots" in how waves move through them. These are
