Type VI secretion systems: Weapons of bacterial destruction
Bacteria can be quite aggressive. Armed with an impressive array of mechanical and biochemical weapons, they don't mess around when it comes to combating their foes. Notable among these armaments is the Type VI Secretion System (T6SS), a membrane-emb.....»»
Study explains regional differences in bird diversity in agroforestry systems
The diversity and ecological functionality of bird communities in tropical agroforestry systems are shaped by the surrounding landscape, in particular the extent and composition of the forest. An international research team led by the University of G.....»»
Neutrons open window to explore space glass
Thanks to human ingenuity and zero gravity, we reap important benefits from science in space. Consider smart phones with built-in navigation systems and cameras......»»
Young people voice concern for improving disaster readiness policies
Nearly half of the young people surveyed on disaster preparedness indicated they felt unprepared for any type of disaster event during a period when catastrophic climate disasters are becoming increasingly frequent, says a University of Michigan rese.....»»
Improving the effectiveness of earthquake early warning systems
Mobile phones have become invaluable for receiving emergency alerts such as weather warnings, evacuation notices and notifications about missing persons. In Japan, where earthquakes are frequent, they are vital for delivering earthquake warnings and.....»»
This modified stainless steel could kill bacteria without antibiotics or chemicals
An electrochemical process developed at Georgia Tech could offer new protection against bacterial infections without contributing to growing antibiotic resistance......»»
Can coal mines be tapped for rare earth elements?
Deposits of designated critical minerals needed to transition the world's energy systems away from fossil fuels may, ironically enough, be co-located with coal deposits that have been mined to produce the fossil fuel most implicated in climate change.....»»
Seeing the color of entangled photons in molecular systems
Spectroscopy is the study of how matter absorbs and emits light and other radiation. It allows scientists to study the structure of atoms and molecules, including the energy levels of their electrons. Classical optical spectroscopy relies on the way.....»»
Low-income groups bear greater health burden in food systems: Study
Across regions where food is produced, emissions from agriculture pose health risks to local populations. Among them, low-income groups are hit the hardest, a study published in Nature Food by researchers at Peking University (PKU) and collaborators.....»»
Using vague language about scientific facts misleads readers
Using subjective phrasing like "scientists believe" makes facts seem like opinions. Enlarge Anyone can do a simple experiment. Navigate to a search engine that offers suggested completions for what you type, and start t.....»»
Tracing the history of perturbative expansion in quantum field theory
Perturbative expansion is a valuable mathematical technique which is widely used to break down descriptions of complex quantum systems into simpler, more manageable parts. Perhaps most importantly, it has enabled the development of quantum field theo.....»»
Bacterial proteins shed light on antiviral immunity
A unique collaboration between two UT Southwestern Medical Center labs—one that studies bacteria and another that studies viruses—has identified two immune proteins that appear key to fighting infections. The findings, published in PLOS Pathogens.....»»
Researchers develop a detector for continuously monitoring toxic gases
Most systems used to detect toxic gases in industrial or domestic settings can be used only once, or at best a few times. Now, researchers at MIT have developed a detector that could provide continuous monitoring for the presence of these gases, at l.....»»
Mystery CRISPR unlocked: A new ally against antibiotic resistance?
CRISPR-Cas systems have revolutionized biotechnology by offering ways to edit genes like a pair of programmable scissors. In nature, bacteria use these systems to fight off deadly viruses. A recent international collaboration led by the University of.....»»
AI can help researchers understand what viruses are up to in the oceans and in your gut
Viruses are a mysterious and poorly understood force in microbial ecosystems. Researchers know they can infect, kill and manipulate human and bacterial cells in nearly every environment, from the oceans to your gut. But scientists don't yet have a fu.....»»

Apple previews iOS 18 accessibility features including eye tracking and music haptics
Apple today announced new accessibility features that will debut later this year in iOS 18 and its other operating systems (although as usual, Apple does not specifically refer to ‘iOS 18’ prematurely). The headline addition is Eye Tracking, w.....»»
Reducing distrust in social media is not straightforward, computer scientists warn
Are anti-misinformation interventions on social media working as intended? It depends, according to a new study led by William & Mary researchers and published in the Proceedings of the CHI Conference on Human Factors in Computing Systems (CHI '24)......»»
Health systems eliminating a form of anesthesia that hangs in the air for more than a decade after use
Philadelphia-area health systems are phasing out a common anesthesia gas that hangs in the atmosphere for 14 years. Desflurane is the most potent greenhouse gas found in hospitals, which are increasingly engaged in efforts to reduce their carbon foot.....»»
Scientists create an "optical conveyor belt" for quasiparticles
Using interference between two lasers, a research group led by scientists from RIKEN and NTT Research have created an "optical conveyor belt" that can move polaritons—a type of light-matter hybrid particle—in semiconductor-based microcavities. Th.....»»
