Bacteria adapt syringe apparatus to changing conditions
Some of the best-known human pathogens—from the plague bacterium Yersinia pestis to the diarrhea pathogen Salmonella—use a tiny hypodermic needle to inject disease-causing proteins into their host's cells, thereby manipulating them. This needle i.....»»
Calcium transport protein in bacteria offers insights for drug development and food safety
Researchers at Umeå University have revealed details on how bacteria use calcium to regulate vital processes in a way that differs from human cells. This breakthrough is significant in the fight against antibiotic resistance and for increasing safet.....»»
Adaptability of trees persists after millions of years of climate change, finds study
Seven of the most common forest trees in Europe have been shown to be able to shelter their genetic diversity from major shifts in environmental conditions. This is despite their ranges having shrunk and the number of trees having fallen sharply duri.....»»
Atmospheric rivers are shifting poleward, reshaping global weather patterns
Atmospheric rivers—those long, narrow bands of water vapor in the sky that bring heavy rain and storms to the U.S. West Coast and many other regions—are shifting toward higher latitudes, and that's changing weather patterns around the world......»»
Compound drought–heat wave events under-recognized in global soils, finds study
Soil is essential for life and plays a crucial role in the Earth's ecosystem, providing support for plant roots and hosting countless microorganisms. In a warming world, it is important to understand how soil hydrothermal conditions, particularly the.....»»
NASA’s Crew-8 astronauts will stay in orbit a little longer
Weather conditions in Florida mean that the return of four crew members from the International Space Station has been delayed again......»»
Research vessel provides comprehensive assessment of the changing Central Arctic Ocean
Sparse sea ice, thousands of data points and samples, a surprising number of animals and hydrothermal vents—those are the impressions and outcomes that an international research team is now bringing back from a Polarstern expedition to the Central.....»»
iOS 18 fixed my motion sickness problem with one new feature
Apple can sometimes dip into hyperbole with its marketing. But every now and then, a new iPhone or software feature truly is “life changing.” For me this year, that feature has been Vehicle Motion Cues in iOS 18, which fixed my motion sickness......»»
Machine learning could improve extreme weather warnings
Because small changes in atmospheric and surface conditions can have large, difficult-to-predict effects on future weather, traditional weather forecasts are released only about 10 days in advance. A longer lead time could help communities better pre.....»»
Scientists discover how innate immunity envelops bacteria
The protein GBP1 is a vital component of our body's natural defense against pathogens. This substance fights against bacteria and parasites by enveloping them in a protein coat, but how the substance manages to do this has remained unknown until now......»»
Biased metrics threaten climate investment where it"s needed most, researchers warn
In a new article published by Nature, experts from the Sustainable Finance Hub say that, although low- and middle-income countries (LMICs) face the most threat from climate change, their ability to respond and adapt to its effects is threatened by a.....»»
Targeting "selfish" bacteria could optimize inhibitors that fight antibiotic resistance
As strains of pathogens resistant to frontline antibiotics become more common worldwide, clinicians are more often turning to combination treatments that degrade this resistance as a first treatment option......»»
Apple hosted ‘Global Police Summit’ to help law enforcement use its products better, per report
Typically when Apple and law enforcement are in the news together, it’s because of a standoff over user privacy. But today, a new report outlines the company’s efforts to build bridges with law enforcement—efforts that may be changing. more.....»»
Barnacle-inspired polymers could present new way to design antibiotics, researchers say
Scientific literature has shown that barnacles that cling to rocks at the seashore use naturally occurring chemicals to clear rock surfaces of bacteria in preparation for laying down their sticky "glue." Since bioengineering professor Abraham Joy's l.....»»
How Chlamydia pneumoniae bacteria use molecular mimicry to manipulate the host cell
Bacteria that cause diseases, so-called pathogens, develop various strategies to exploit human cells as hosts to their own advantage. A team of biologists from Heinrich Heine University Düsseldorf (HHU), together with medical professionals and exper.....»»
Octopus-inspired adhesive works well in wet conditions
In research published in Advanced Science, investigators drew inspiration from the octopus to develop an adhesive that achieves strong attachment and controlled release on varied substrates in wet and underwater environments. The feat could have nume.....»»
Researchers discover how plants produce a novel anti-stress molecule
New research identifies for the first time the genes that help plants grow under stressful conditions—with implications for producing more sustainable food crops in the face of global climate change......»»
Increase access to nature in all daily environments and in education, say environmental scientists
Although access to nature is a basic human right, people's actual use of green spaces is subject to inequalities. A Kobe University-led research team analyzed what conditions make it more likely that people are exposed to nature across generations: t.....»»
Research team develops metallodrug-antibiotic combination strategy to combat superbugs
Antimicrobial resistance (AMR) bacterial infections have become a serious problem threatening human health worldwide. The overuse of antibiotics has promoted drug-resistant mutations in bacteria, causing almost all clinically used antibiotics to deve.....»»
Report on global water resources: Conditions in 2023 were either too dry or too wet
Not only was 2023 characterized by unprecedentedly high temperatures but also by excessive droughts in many parts of the world as well as floods in other areas. The World Meteorological Organization (WMO) has now presented its third report on the sta.....»»
Trees" own beneficial microbiome could lead to discovery of new treatments to fight citrus greening disease
Citrus trees showing natural tolerance to citrus greening disease host bacteria that produce novel antimicrobials that can be used to fight off the disease, our recent study shows. We found the trees at an organic farm in Clermont, Florida......»»
