"Superbugs" with hypervirulence and carbapenem resistance in Klebsiella pneumoniae
A new bacterial threat, the carbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-hvKP), is rapidly spreading in clinical environments in China, posing a significant public health challenge. This pathogen is simultaneously multidrug-resistant,.....»»
Physicists trap electrons in a 3D crystal for the first time
Electrons move through a conducting material like commuters at the height of Manhattan rush hour. The charged particles may jostle and bump against each other, but for the most part, they're unconcerned with other electrons as they hurtle forward, ea.....»»
Study shows historical volcanic eruptions triggered short-term global cooling
New international research led by the University of St Andrews reveals historical high latitude volcanic eruptions caused dramatic, but short-lived climate cooling......»»
Measuring the impact of desert greening
Long-term satellite data shows a significant cooling effect of vegetation on land surface temperature. The searing heat of the Arabian Peninsula translates to a population vulnerable to heat stress. As temperatures continue to rise, effective strateg.....»»
AMD starts bringing its own tiny CPU cores to new Ryzen 7040 laptop chips
AMD has already announced some of these chips without mentioning Zen 4c cores. Enlarge / Unlike Intel's E-cores, AMD's Zen 4c supports all the same capabilities as Zen 4, just in a smaller package with lower clock speeds. (credit.....»»
Chloroplasts do more than photosynthesis: They"re also a key player in plant immunity
Scientists have long known that chloroplasts help plants turn the sun's energy into food, but a new study, led by plant biologists at the University of California, Davis, shows that they are also essential for plant immunity to viral and bacterial pa.....»»
How bacteria support wound healing
Although they were not recognized as agents of disease until the late 19th century, the detrimental effects of bacterial infections have been known to humans for thousands of years. Some have even become mythical—for example, during the American Ci.....»»
Oxygen vacancy boosting Fenton reaction: A novel approach to fight bacterial infection in bone scaffold
The field of artificial bone transplantation has faced a significant barrier: bacterial infection, a common culprit that often leads to transplant failure and, in severe cases, devastating consequences such as amputation......»»
Pixel 8 Pro teardown reveals better cooling, interior “Google” branding
For the second year in a row, there's an even bigger graphite thermal pad. The guts of the Pixel 8 Pro, once the cooling pad has been removed. Check out that sweet Google logo.....»»
Eureka: With GPT-4 overseeing training, robots can learn much faster
GPU-based physics simulator speeds up reality by "1,000x" while GPT-4 calls the shots. Enlarge / In this still captured from a video provided by Nvidia, a simulated robot hand learns pen tricks, trained by Eureka, using simultane.....»»
Electrons are quick-change artists in molten salts, chemists show
In a finding that helps elucidate how molten salts in advanced nuclear reactors might behave, scientists have shown how electrons interacting with the ions of the molten salt can form three states with different properties. Understanding these states.....»»
Electron-rich metals make ceramics tough to crack
Researchers have discovered a way to make ceramics tougher and more resistant to cracking. By building these materials using a blend of metal atoms possessing more electrons in their outer shell, a team led by engineers at the University of Californi.....»»
Manipulating collective motions of electrons and solvent molecules in a polar liquid
Researchers at the Max-Born-Institute have now mapped the linear and nonlinear optical polaron response using ultrafast two-dimensional spectroscopy in the THz frequency range. As they discuss in the current issue of Physical Review Letters, multi-ph.....»»
California supervolcano is cooling off but may still cause quakes
Since the 1980s, researchers have observed significant periods of unrest in a region of California's Eastern Sierra Nevada mountains characterized by swarms of earthquakes as well as the ground inflating and rising by almost half an inch per year dur.....»»
A physics milestone: Miniature particle accelerator works
Particle accelerators are crucial tools in a wide variety of areas in industry, research and the medical sector. The space these machines require ranges from a few square meters to large research centers. Using lasers to accelerate electrons within a.....»»
Yeast speeds discovery of medicinal compounds in plants
Cornell researchers have harnessed the power of baker's yeast to create a cost-effective and highly efficient approach for unraveling how plants synthesize medicinal compounds, and used the new method to identify key enzymes in a kratom tree......»»
Scientists discover the possible triggers for bacterial pathogens, opening the door for new treatment strategies
The legendary Alexander Fleming, who famously discovered penicillin, once said "never to neglect an extraordinary appearance or happening." And the path of science often leads to just that. New UNLV research is turning the page in our understanding o.....»»
Examining the function of salmon cooling stations
You've heard of the salmon run: upon reaching sexual maturity, wild Atlantic salmon, which are born in freshwater rivers but spend most of their adult life in the ocean, swim upstream all the way back to their birthplace to spawn. This remarkable mig.....»»
The deep slumber of a hospital pathogen: Why infections with Acinetobacter baumannii can flare up again and again
The bacterium Acinetobacter baumannii is an extremely dangerous pathogen that is found, among other places, in hospitals. Many of the bacterial strains are resistant to different classes of antibiotics. Infections with Acinetobacter baumannii were fi.....»»
