Deadly virus"s pathway to infect cells identified
Rift Valley fever virus causes economically devastating outbreaks of hemorrhagic fever in livestock such as sheep, goats and cattle. These mosquito-borne outbreaks lead to infection in people working with dead or dying animals, sometimes causing hund.....»»
Researchers find a new organelle evolving
A "nitroplast" converts nitrogen from the air to a chemically useful form. Enlarge / A photo of Braarudosphaera bigelowii with the nitroplast indicated by an arrowhead. (credit: Tyler Coale) The complex cells that under.....»»
Scientists find blue light makes buildings more deadly to migrating birds
Bird collisions with buildings are nothing new, but a new study by scientists at The University of New Mexico sheds light on a potential cause......»»
Genetic underpinnings of environmental stress identified in model plant
Plants can be temperamental. Even weeds along the side of highways or pushing their way up in the cracks of concrete sidewalks can get stressed out by dehydration, cold, excess salt and more. Researchers at Hiroshima University have identified 14 gen.....»»
A compact metasurface array-based system for single-shot spectroscopic ellipsometry measurement
Spectroscopic ellipsometry is widely adopted in semiconductor processing, such as in the manufacturing of integrated circuits, flat display panels, and solar cells. However, a conventional spectroscopic ellipsometer, as shown in Fig.1a, typically mod.....»»
Scientists find new ways to convert inhibitors into degraders, paving the way for future drug discoveries
Researchers have discovered ways to convert inhibitor-style targeted cancer drugs into small molecules known as degraders, which help destroy cancer-promoting proteins in cells......»»
Advanced microscopy technique offers a new look inside cells
Imagine tuning into a football game, but all of the players are invisible except for the two quarterbacks. Without being able to see the orchestrated movements of the full teams, this would be a very confusing game to watch......»»
Tropical coral-infecting parasites discovered in cold marine ecosystems
Parasites thought only to infect tropical coral reefs have been discovered in a large variety of creatures in cold marine ecosystems along the Northeast Pacific, according to new research from University of British Columbia botanists......»»
A new tool for tracing the family trees of cells
EPFL researchers have developed GEMLI, a pioneering tool that could democratize and vastly improve how we study the journey of cells from their embryonic state through to specialized roles in the body, as well as their changes in cancer and other dis.....»»
Apple alerts some iPhone users that they were targets of ‘mercenary spyware attack’
Apple is alerting users to a new instance of an identified mercenary spyware attack on the iPhone. Possible victims have been sent an email from Apple describing how the attack could “remotely compromise the iPhone”. Victims are being notified in.....»»
Microplastic "hotspots" identified in Long Island Sound
Forensic and environmental experts have teamed up to develop a new scientific method to pinpoint microplastic pollution 'hotspots' in open waters. A study by Staffordshire University, The Rozalia Project for a Clean Ocean, and Central Wyoming College.....»»
Scientists reconstruct assembly of the human centriole, image by image, for the first time
Cells contain various specialized structures—such as the nucleus, mitochondria or peroxisomes—known as "organelles." Tracing their genesis and determining their structure is fundamental to understanding cell function and the pathologies linked to.....»»
New spectrometer helps identify alternative catalyst materials for affordable hydrogen fuel cells
Fuel cells are quickly becoming a viable, clean energy alternative to commonly used fossil fuels, such as gasoline, coal, and oil. Fossil fuels are non-renewable energy resources that release carbon dioxide into the atmosphere......»»
LSD1 promotes FSH responsive follicle formation by regulating autophagy and repressing Wt1 in granulosa cells: Study
A study published in Science Bulletin has been led by Prof. Chao Wang (China Agricultural University), Prof. Guoliang Xia (China Agricultural University) and Prof. Fengchao Wang (National Institute of Biological Sciences)......»»
We can"t eradicate deadly cane toads—but there"s a way to stop them killing wildlife
Australia can claim more than its fair share of environmental blunders, but the introduction of cane toads in 1935 surely ranks as one of the worst......»»
Kamikaze bacteria explode into bursts of lethal toxins
If you make a big enough toxin, it's difficult to get it out of the cells. Enlarge / The plague bacteria, Yersina pestis, is a close relative of the toxin-producing species studied here. (credit: Callista Images) Life-fo.....»»
Scientists discover new phage resistance mechanism in phage-bacterial arms race
One of the most abundant and deadliest organisms on Earth is a virus called a bacteriophage (phage). These predators have lethal precision against their targets—not humans, but bacteria. Different phages have evolved to target different bacteria an.....»»
Bias distribution and regulation in photoelectrochemical overall water-splitting cells
The photoelectrochemical (PEC) overall water-splitting reaction (OWS) has been fully developed in the past decade, especially in new catalysts, characterization methods and reaction mechanisms. Compared with the hydrogen evolution reaction (HER), the.....»»
Researchers map structure of mitochondria at different life stages
Mitochondria, organelles with an inner and outer membrane, are responsible for creating the energy that cells use to survive, and their morphology is key to accomplishing this task. The inner mitochondrial membrane contains folds, called cristae, tha.....»»
Researchers bring 60-year-old dormant algae cells to life
New research at Åbo Akademi University, Finland, has managed to circumvent previous challenges in finding out how microalgae adapt to global warming by studying up to 60-year-old microalgae cells from the Archipelago Sea. Some microalgae form restin.....»»
New signaling pathway decoded in the decomposition of damaged lysosomes
Lysosomes are surrounded by a lipid bilayer that separates the acidic environment and the digestive enzymes of the organelle from the cytoplasm. Damage to this layer—lysosomal membrane permeabilization, or LMP for short—can trigger inflammation a.....»»
