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......»»
How mosquito larva guts could help create highly specific insecticides
Did you know that the world's deadliest animal is the mosquito? And Aedes aegypti is one of the most dangerous. This bug spreads viruses that cause dengue fever, which was recently declared as an epidemic in Puerto Rico......»»

A simple, inexpensive way to make carbon atoms bind together
The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon—a carbon atom bond.....»»

A robot hopper to explore the moon"s dangerous terrain
Intuitive Machines recently had a major breakthrough, successfully becoming the first non-governmental entity to land on the moon in February. At least the landing was partially successful—the company's Odysseus lander ended up on its side, though.....»»
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.....»»
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.....»»
Catkins are flowering at different times, threatening their pollination and the wildlife that feed on them
As the days grow longer and the air warms up, nature is bursting back to life. Even before their leaves return, trees produce delicate, fuzzy structures known as catkins. These tiny, downy threads, often described as kitten tails (thanks to a fun tra.....»»
Wound treatment hydrogel infused with amino acid kills bacteria naturally and promotes cell growth
Hydrogels are popular for use in skin ailments and tissue engineering. These polymer-based biocompatible materials are useful for their abilities to retain water, deliver drugs into wounds, and biodegrade. However, they are complicated to manufacture.....»»
Researchers explain how green algae and bacteria together contribute to climate protection
A research team at Friedrich Schiller University Jena, Germany has now found a bacterium that forms a team with a green alga. Both microorganisms support each other in their growth. Additionally, the bacterium helps the microalga to neutralize the to.....»»
