In recent years, astronomy has seen itself in a bit of crisis: Although we know that the Universe expands, and although we know approximately how fast, the two primary ways to measure this expansion do not agree. Now astrophysicists suggest a novel method which may help resolve this tension. Read more ›

Young people (24 years and younger) spend an average of six hours a day online, primarily using their smartphones, according to new research. Older people (those 24 years and older) spend 4.6 hours online. Read more ›

Priming users about the motives of an AI agent had a significant impact on their perceptions of that agent and how effective they believed this AI mental health companion was, according to a new study. Not only did priming change users’ perceptions, it also changed how they interacted with the chatbot and how the chatbot responded, creating a feedback loop. Read more ›

At the core of uncovering extreme events such as floods is the physics of fluids – specifically turbulent flows. Researchers leveraged a computer-vision deep learning technique and adapted it for nonlinear analysis of extreme events in wall-bounded turbulent flows, which are pervasive in numerous physics and engineering applications and impact wind and hydrokinetic energy, among others. Results show the technique employed can be invaluable for accurately identifying the sources of... Read more ›

If forensic experts have access to a suspect’s gun, they can compare the microscopic markings from discarded shell casings with those found at a crime scene. Finding and reporting a mismatch can help free the innocent, just as a match can incriminate the guilty. But new research reveals mismatches are more likely than matches to be reported as “inconclusive” in cartridge-case comparisons. Read more ›

Along the Asian coast lines there are many areas where rural communities experience alarming rates of sea level rises due to land subsidence up to 10 cm per year. This causes tremendous challenges on how to live there and protect these coasts. Scientists have now investigated the potential and limitation of mangrove restoration as a cost-effective and sustainable solution for coastal protection in rapidly subsiding areas. Read more ›

A chloroplast enzyme safeguards plants against pathological protein aggregation that causes Huntington’s and other neurodegenerative diseases. New research may have found a way to 'copy' the mechanism for application in human cells. Read more ›

It’s long been understood that human settlement contributes to conditions that make Pacific Islands more susceptible to wildfires, such as the devastating Aug. 8 event that destroyed the Maui community of Lahaina. But a new study from fire scientist shows that climate is an undervalued part of the equation. Read more ›

A new machine-learning approach helps scientists more efficiently identify the optimal intervention to achieve a certain outcome in a complex system, such as genome regulation, requiring far fewer experimental trials than other methods. Read more ›

A new study reveals the crucial role of vascular system cells -- known as pericytes -- in the formation of long-term memories of life events -- memories that are lost in diseases such as Alzheimer's disease. Read more ›

Researchers identified and characterized a new cellular compartment in vertebrate cells termed chr('39')exclusomechr('39') that might be a precursor of today’s eucaryotic nucleus. The study reveals that mammalian cells recognize, cluster, sort and keep extrachromosomal DNA -- like transfected plasmid DNA and endogenous circular DNAs originating from telomeres of the chromosome -- away from chromosomal DNA. That suggests that there is a cell autonomous genome defense system. Read more ›

Investigators have developed a new approach for treating invasive bladder cancer without the need for surgical removal of the bladder. Removing the bladder is currently a standard approach when cancer has invaded the muscle layer of the bladder. Read more ›

People frequently exposed to racial or ethnic discrimination may be more susceptible to obesity and related health risks in part because of a stress response that changes biological processes and how we process food cues, according to new research. Read more ›

Increased government investment in climate change mitigation is prompting agricultural sectors to find reliable methods for measuring their contribution to climate change. With that in mind, scientists have proposed a supercomputing solution to help measure individual farm field-level greenhouse gas emissions. Read more ›

The annual burning of crop residue in India causes widespread air pollution, particularly in the northwestern regions. A group of international researchers has used low-cost yet reliable instruments to gauge the effects of air pollution in these areas. Read more ›

For the first time, in a unique laboratory experiment at CERN, researchers have observed individual atoms of antihydrogen fall under the effects of gravity. In confirming antimatter and regular matter are gravitationally attracted, the finding rules out gravitational repulsion as the reason why antimatter is largely missing from the observable universe.
