Phys.org / Japan's ancient 'tigers' were actually cave lions, DNA evidence shows
There aren't any native lion or tiger populations living in Japan today, but this was not always the case. Fossil evidence indicates that at least one species of large cat roamed the archipelago during the Late Pleistocene—a ...
Phys.org / Elevated E. coli, staph still detected in Potomac river 4 weeks after sewage spill
Nearly a month after a wastewater pipe broke and spewed hundreds of millions of gallons of raw sewage into the Potomac River just north of Washington, D.C., the latest water testing results from the University of Maryland ...
Phys.org / Silicon quantum processor detects single-qubit errors while preserving entanglement
Quantum computers are alternative computing devices that process information, leveraging quantum mechanical effects, such as entanglement between different particles. Entanglement establishes a link between particles that ...
Medical Xpress / A potential new lymphedema target: Clearing cholesterol deposits to reduce swelling
An international team led by National University of Singapore researchers has linked secondary lymphedema to excessive cholesterol buildup inside skin and around lymphatic vessels. Excess cholesterol deposition tracked with ...
Phys.org / How shaming unethical brands makes companies improve their behavior
Recent investigations have uncovered forced labor in agricultural supply chains, illegal fishing feeding supermarket freezers, deforestation embedded in everyday food products, and unsafe conditions in factories producing ...
Tech Xplore / The giant fire tornado that could save our oceans
In the frantic hours following an offshore oil spill, emergency responders face a destructive decision: let the oil spread or ignite it. Once ignited, it creates an "in-situ" fire pool that stops the oil from spreading and ...
Phys.org / Mirror image pheromones help beetles 'swipe right' to find mates
There are many ways to communicate with prospective romantic partners. If you are a Japanese scarab beetle, it's a matter of distinguishing left from right. New work from U.S. and Chinese scientists, published this week in ...
Phys.org / Twelve-year tracking suggests killer whales do not always drive shark disappearances
While killer whales (Orcinus orca) can trigger the immediate departure of white sharks (Carcharodon carcharias), extended absences from their aggregation sites are also part of the sharks' natural behavior, new research reveals.
Phys.org / Dramatic changes in upper atmosphere are responsible for recent droughts and bushfires: New research
Over the past decade, southern Australia has suffered numerous extreme weather and climate events, such as record-breaking heat waves, bushfires, two major droughts and even flash flooding.
Tech Xplore / Physics-aware AI algorithm uses Newton's third law to keep simulations stable
A team of EPFL researchers has developed an AI algorithm that can model complex dynamical processes while taking into account the laws of physics—using Newton's third law. Their research is published in the journal Nature ...
Tech Xplore / Humanoid robots that 'catch themselves' instead of falling: What a new walking algorithm changes
While the statement, "Humanoid robots are coming," might cause anxiety for some, for one Georgia Tech research team, working with humanlike robots couldn't be more exciting. The researchers have developed a new "thinking" ...
Tech Xplore / Personalization features can make LLMs more agreeable, potentially creating a virtual echo chamber
Many of the latest large language models (LLMs) are designed to remember details from past conversations or store user profiles, enabling these models to personalize responses. But researchers from MIT and Penn State University ...
