Researchers can now pinpoint direction of elusive subatomic particles key to understanding black holes, other cosmic events
A unique telescope buried in Antarctic ice promises unparalleled insight into such extraordinary phenomena as colliding black holes, gamma-ray bursts, the violent cores of distant galaxies and the wreckage of exploded stars.
An international team of physicists and astronomers, which includes UC Irvine researchers, report that the AMANDA telescope is cap
Salmonella, E. coli, shigellosis, hepatitis A, and Norwalk — these food-borne diseases can produce symptoms that run from the mild to life-threatening. The young and old are particularly vulnerable and while consumption of beef and poultry have been the most common sources of such infections, fresh fruits and vegetables are being increasingly implicated in such outbreaks. So much so, that plant disease scientists are now taking a closer look at this issue.
“Historically, human pathogens l
Like a well-trained soldier with honed survival skills, the common bacterium, Group A Streptococcus (GAS), sometimes can endure battle with our inborn (innate) immune system and cause widespread disease. By investigating the ability of combat-ready white blood cells (WBCs) to ingest and kill GAS, researchers have discovered new insights into how this disease-causing bacteria can evade destruction by the immune system. The research is being published this week in the Online Early Edition of the Procee
A joint research project by scientists in Cardiff, UK, has developed a new protein, which could end the suffering of thousands.
The research, by scientists at Cardiff University and the University of Wales College of Medicine (UWCM), and funded mainly by the Wellcome Trust, is designed to tackle the problem of chronic inflammation – which can lead to serious disorders such as rheumatoid arthritis and bacterial peritonitis.
Now a two-year development programme is getting un
By solving a long-standing puzzle about how the influenza virus assembles its genetic contents into infectious particles that enable the virus to spread from cell to cell, scientists have opened a new gateway to a better understanding of one of the worlds most virulent diseases.
This insight into the genetic workings that underpin infection by flu, reported today (January 27, 2003) in the Proceedings of the National Academy of Sciences (PNAS), provides not only a better basic understa
While about 80 percent of people with epilepsy gain significant relief from drug therapy, the remaining 20 percent have seizures that cannot be controlled by medications. Many of these people have a particular type of epilepsy called partial epilepsy. A new study shows that people with partial epilepsy often have seizures controlled by medications for years before their seizures become drug-resistant. The study also found that periods when seizures stopped for a year or more are common in these patie
Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom “recoils” in…
The technique opens possibilities for exploring exotic states of matter and building new quantum materials. Proximity is key for many quantum phenomena, as interactions between atoms are stronger when the…
Research at the south pole studied the mysterious quantum structure of space and time. Einstein’s theory of general relativity explains that gravity is caused by a curvature of the directions…
An international research team is examining the molecular mechanisms that enabled plants to colonize the surface of the Earth. Around 550 million years ago, the Earth’s surface was a barren…
New sensor is six orders of magnitude more sensitive than the next best thing. A research team at Pitt led by Alexander Star, a chemistry professor in the Kenneth P. Dietrich…
New research shows how tiny plant-like organisms hitch a ride on ocean currents to reach darker and deeper depths, where they impact carbon cycling and microbial dynamics in the subtropical…
Charge-recharge cycling of lithium-superrich iron oxide, a cost-effective and high-capacity cathode for new-generation lithium-ion batteries, can be greatly improved by doping with readily available mineral elements. The energy capacity and…
Engineers in Australia have found a new way to make power-pole insulators resistant to fire and electrical sparking, promising to prevent dangerous pole-top fires and reduce blackouts. Pole-top fires pose…
Potential alternative to widely used contrast agent gadolinium. Some of the world’s greatest discoveries happened by accident. While the discovery of diamond dust’s potential as a future MRI contrast agent…
Parkinson’s disease is one of the most prevalent neurodegenerative conditions. It causes motor impairments such as tremors, slow movement, muscle stiffness, and balance problems. The individual course of the disease…
A four-legged robot trained with machine learning by EPFL researchers has learned to avoid falls by spontaneously switching between walking, trotting, and pronking – a milestone for roboticists as well…
TUM professor uses ChatGPT for choreographies with flying robots. Prof. Angela Schoellig has proved that large language models can be used safely in robotics. ChatGPT develops choreographies for up to…
