Making crops colorful for easier weeding by robots
To make weeding easier, scientists suggest bioengineering crops to be colorful or to have differently shaped leaves so that they can be more easily distinguished from their wild and weedy counterparts. This could involve altering the crops' genomes s.....»»
Improved mid-infrared nanoscopy enables 30 times clearer view of the insides of bacteria
A team at the University of Tokyo have constructed an improved mid-infrared microscope, enabling them to see the structures inside living bacteria at the nanometer scale. Mid-infrared microscopy is typically limited by its low resolution, especially.....»»
Multi-drug resistant bacteria found on International Space Station mutate to become functionally distinct
Principal Investigator Dr. Kasthuri Venkateswaran of NASA's Jet Propulsion Laboratory led a team that studied 13 strains of the bacterial species Enterobacter bugandensis that were isolated from the International Space Station (ISS). E. bugandensis i.....»»
Scientists discover how soil microbes survive in harsh desert environments
Prolonged droughts followed by sudden bursts of rainfall—how do desert soil bacteria manage to survive such harsh conditions? This long-debated question has now been answered by an ERC project led by microbiologist Dagmar Woebken from the Centre fo.....»»
Silver-based micromotors that eliminate bacteria can move freely in aqueous media
Researchers at ICIQ in Tarragona have developed a simple technique to produce microscopic crystals that activate in the presence of light, releasing silver ions with antimicrobial activity......»»
Q&A: For many prisoners, gang affiliation drops off after release
Nearly everyone who enters prison in the United States eventually leaves. In fact, every year about 600,000 people are released from federal and state prisons, according to U.S. Department of Justice data......»»
Uranium-immobilizing bacteria in clay rock: Exploring how microorganisms can influence the behavior of radioactive waste
When designing repositories for high-level radioactive waste in deep geological layers, various factors must be carefully considered to ensure their long-term safety. Among other things, natural communities of microorganisms can influence the behavio.....»»

In the field of organic chemistry, scientists are always looking out for new types of reactions to unlock synthesis routes for challenging compounds. Most of the progress that we have witnessed in pharmaceutics and agrochemicals over the past few dec.....»»
Removal of App Store"s first emulator leaves more questions than answers
The controversial GBA4iOS that hit the top of the App Store is gone, and the rules Apple cited for its removal leave us with more questions than answers about the future of emulators on the platform.Emulator app iGBA is accused of copying another dev.....»»
NASA discovered bacteria that wouldn"t die. Now it"s boosting sunscreen.
While disinfecting spacecraft headed for Mars, NASA found a stubborn type of bacteria that was tough to clean but great at withstanding UV radiation. Many people associate NASA with exploring new worlds in space, but few know it's also finding.....»»
Study lists world"s "forever chemical" hotspots
Dangerous concentrations of long-lingering "forever chemicals" have been found in surface and groundwater worldwide, according to a study released Tuesday that showed Australia, the United States and Europe as hotspots......»»
TSMC’s $65 billion bet still leaves US missing piece of chip puzzle
TSMC will begin making 2 nm chips in Arizona starting in 2028. Enlarge / President Biden speaking at the official opening of TSMC’s first Arizona fabrication plant in December 2022. The Taiwanese chipmaker plans to start manufa.....»»
Q&A: El Niño drought leaves Zimbabwe"s Lake Kariba only 13% full—a disaster for people and wildlife
Water levels at Lake Kariba in Zimbabwe have dropped dramatically because of the latest El Niño drought. The country's president, Emmerson Mnangagwa, has declared a national disaster......»»
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.....»»
More than two dozen Colorado water systems exceed EPA"s new limits on "forever chemicals"
Twenty-nine of the more than 2,000 water treatment facilities in Colorado do not meet strict new federal limits on the amount of dangerous "forever chemicals" in their drinking water supplies and it will cost millions to clean those toxins out of the.....»»
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.....»»
Discovery of the first fractal molecule in nature
An international team of researchers led by groups from the Max Planck Institute in Marburg and the Philipps University in Marburg has stumbled upon the first regular molecular fractal in nature. They discovered a microbial enzyme—citrate synthase.....»»
A new algorithm to predict information superspreaders in social media
Understanding how information flows in social networks is critical to counteracting dangerous misinformation, promoting the spreading of news, and designing healthy online social environments. Scholars have long realized the role of information super.....»»
