Disrupted movement makes macrophages more lethal to tuberculosis bacteria
Macrophages—the front line of our immune system—protect us from infections. But in the case of the tuberculosis bacteria, this often goes wrong. The group of Annemarie Meijer from the Leiden Institute of Biology has now discovered that macrophage.....»»
New Apple Watch data shows the average person takes 334 days to walk/run a marathon
I can’t run a marathon (and I don’t plan on trying), but new data from the Apple Heart and Movement Study offers some insight into the training habits of people who do. Published by Brigham and Women’s Hospital on Friday, the data reveals th.....»»
Apple health study proves anybody can run a marathon -- given enough time
For five years, Apple has been running a Heart and Movement Study using the Apple Watch, and its researchers have now examined the training and cardio exercises that marathon runners do.You may never have seen it — all Apple Watch exercise rings co.....»»
New study reveals novel approach for combating "resting" bacteria
Most disease-causing bacteria are known for their speed: In mere minutes, they can double their population, quickly making a person sick. But just as dangerous as this rapid growth can be a bacterium's resting state, which helps the pathogen evade an.....»»
Scientists discover first nitrogen-fixing organelle
Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria in root nodules. But a recen.....»»
18 essential movies about the fight for women"s equality
From "On the Basis of Sex" to "Suffragette," pay your respects to everyday activists, revolutionaries, and rebels who paved the way for women's equality. The modern feminist movement isn’t an ambiguous, shapeless mist that has acted of it.....»»
Researchers resolve old mystery of how phages disarm pathogenic bacteria
Bacterial infections pose significant challenges to agriculture and medicine, especially as cases of antibiotic-resistant bacteria continue to rise. In response, scientists at Texas A&M AgriLife Research are elucidating the ways that bacteria-infecti.....»»
New approach needed to save Australia"s non-perennial rivers
Non-perennial rivers, which stop flowing at some point each year, dominate surface water movement across Australia, yet monitoring the continued health of these vital waterways demands a new type of research attention......»»
Humans shape the journey of mud, study reveals
Mud can be surprisingly clear. A global team of scientists has uncovered a hidden truth: Human actions are shaping the journey of mud. Over the course of decades, our activities have wielded significant influence over the movement and dispersion of m.....»»
Understanding the northward movement of the subtropical westerly jet in changing climates
The subtropical westerly jet is a high-altitude, fast-moving air current that flows from west to east in the subtropical region of the Earth's atmosphere. It's an important part of atmospheric circulation, influencing weather patterns and climate con.....»»
A microbial plastic factory for high-quality green plastic
Engineered bacteria can produce a plastic modifier that makes renewably sourced plastic more processable, more fracture-resistant and highly biodegradable even in seawater. The Kobe University development provides a platform for the industrial-scale,.....»»
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.....»»
When an antibiotic fails: Scientists are using AI to target "sleeper" bacteria
Since the 1970s, modern antibiotic discovery has been experiencing a lull. Now the World Health Organization has declared the antimicrobial resistance crisis as one of the top 10 global public health threats......»»
Research unveils biochemical defenses against chemical warfare
In the clandestine world of biochemical warfare, researchers are continuously seeking innovative strategies to counteract lethal agents. Researchers led by Jin Kim Montclare, Professor in the Department of Chemical and Biomolecular Engineering, have.....»»
Researchers discover two vesicle fusion mechanisms while studying vesicle movement in living cells
Cells intake substances from the outside world by encapsulating them in vesicles called endosomes, which are subsequently transported throughout the cell. During the transport process, vesicles fuse with other intracellular organelles. However, obser.....»»
Protesters close Chicago Apple Store over Palestinian employee firing
A small group of demonstrators disrupted the Lincoln Park Apple Store in Chicago on Saturday to protest Apple's use of labor in Africa and its disciplining of at least one employee wearing pro-Palestinian clothing items.The protest, which took place.....»»
Research introduces digital games along with multimedia debriefing to address cyberbullying
The global COVID-19 pandemic caused much suffering and tragedy and continues to do so. One aspect of our everyday lives that was massively disrupted was education. Conventional classroom teaching methods had to be digitized urgently during lockdowns.....»»
Attack and defense in the microverse: How small RNA molecules regulate viral infections of bacteria
Viruses need hosts. Whether it's measles, the flu or coronavirus, viral pathogens cannot multiply or infect other organisms without the assistance of their hosts' cellular infrastructure. However, humans are not the only ones affected by viruses: ani.....»»
Beyond TSMC, Apple"s supply chain will be disrupted by the Taiwan earthquake
The Taiwan earthquake will cause issues for a number of Apple suppliers beyond TSMC, but the supply chain's impact probably won't be severe long-term, thanks to globalization. Here are some of Apple's suppliers that the company will need to keep an e.....»»
Study describes zinc oxide nanoparticle strategy for inactivation of multidrug-resistant bacteria
An article published in the Journal of Environmental Chemical Engineering describes a possible strategy for promoting selective inhibition of multidrug-resistant bacteria, which are increasingly abundant owing to the indiscriminate use of antibiotics.....»»
