San Francisco, CA - June 21, 2019 - New research has found that six probiotic Bacillus strains are resistant to several antibiotics. Genetic analysis of other Bacillus strains has shown genes that contribute to antibiotic resistance towards various types of drugs and methods in which they can still grow in their presence. The research is presented at ASM Microbe, the annual meeting of the American Society for Microbiology.
San Francisco, CA - June 21, 2019 - Salt-tolerant bacteria grown in brine were able to revive after the brine was put through a cycle of drying and rewetting. The research has implications for the possibility of life on Mars, as well as for the danger of contaminating Mars and other planetary bodies with terrestrial microbes. The research is presented at ASM Microbe 2019, the annual meeting of the American Society for Microbiology.
Children need protection when using programmable Internet computing devices - and Lancaster University scientists have drawn up new guidelines to help designers build in safeguards.
Young people are growing up in a digital world where everyday objects contain sensors and stream data to and from the Internet - a trend known collectively as the Internet of Things (IoT).
Children are also getting hands-on - using small-scale easy-to-program devices such as the BBC micro:bit to experiment and get creative with digital technologies.
Virginia Tech researchers discovered that wheat plants "sneezing" off condensation can vastly impact the spread of spore-borne diseases, such as wheat leaf rust, which can cause crop yield losses of up to 20 percent or more in the United States and higher average losses in less developed agricultural nations.
- The deployment, successfully achieved by Ericsson and Telefónica, includes a new 5G Massive MIMO Radio running on 3.5GHz band, along with virtual Evolved Packet Core and User Data Consolidation.
- Part of the 5G EVE project, use cases of 5G-controlled Automated Guided Vehicles (AGVs) and real-time video analytics running in the 5TONIC lab have been demonstrated by Ericsson, Telefónica and IMDEA Networks at EuCNC event in Valencia
Ornithologists from St Petersburg University, Elmira Zaynagutdinova and Yuriy Mikhailov, studied the features of the great crested grebes (Podiceps cristatus) nesting in the nature reserve 'North Coast of the Neva Bay'. It turned out that some birds have learned to change the time of egg incubation in order to breed along with black-headed gulls and black terns. This strategy makes it possible for them to use the 'protection services' of neighbouring birds.
In a new survey of the sub-seafloor off the U.S. Northeast coast, scientists have made a surprising discovery: a gigantic aquifer of relatively fresh water trapped in porous sediments lying below the salty ocean. It appears to be the largest such formation yet found in the world. The aquifer stretches from the shore at least from Massachusetts to New Jersey, extending more or less continuously out about 50 miles to the edge of the continental shelf. If found on the surface, it would create a lake covering some 15,000 square miles.
Background
Neurons1 and astrocytes2 are prominent cell types in the cerebral cortex. Neurons are the primary information processing cells in the brain, whereas astrocytes support and modulate their functions. For sound functioning of the brain, it is crucial that proper numbers of neurons and astrocytes are generated during fetal brain development. The brain could not function correctly if only neurons or astrocytes were generated.
Nanotechnology and nanoscience are enabled by nanofabrication. Electron-beam lithography (EBL), which makes patterns down to a few nanometers, is one of the fundamental pillars of nanofabrication. In the past decade, significant progress has been made in electron-beam-based nanofabrication, such as the emerging ice lithography (IL) technology, in which ice thin-films are used as resists and patterned by a focused electron-beam.
Understanding how shock waves affect structures is crucial for advancements in material science research, including safety protocols and novel surface modifications. Using X-ray diffraction probes, scientists at the Institute of Materials Structure Science of KEK, Tokyo of Tech, Kumamoto University, and University of Tsukuba studied the deformation of polycrystalline aluminum foil when subjected to a laser-driven shock wave.
Sleep disturbances and mental health challenges are putting close to half of America's firefighters at high risk of emotional fatigue and exhaustion, new research shows.
The research was conducted by Monash University in Australia in collaboration with Brigham and Women's Hospital in Boston, USA.
Of the 6,307 firefighters from 66 fire departments across the USA that took part in this cross-sectional study, 49% exhibited high levels of physical and emotional burnout in at least one area.
Leipzig/Copenhagen/Villigen/Beijing. For the first time, an international research team led by the Leibniz Institute for Tropospheric Research (TROPOS) has investigated atmospheric ice nucleating particles (INPs) in ice cores, which can provide insights on the type of cloud cover in the Arctic over the last 500 years. These INPs play an important role in the formation of ice in clouds and thus have a major influence on the climate. So far, however, there are only a few measurements that date back only a few decades.
In sudden death in epilepsy, people stop breathing for no apparent reason and die. Now, a group of UConn neuroscientists have a lead as to why, they report in the journal eLife.
"People with epilepsy have a high mortality rate, but it's mysterious," says Dan Mulkey, a neuroscientist in UConn's physiology and neurobiology department.
More than one of every 1,000 people with epilepsy die each year from what's called sudden unexpected death in epilepsy (SUDEP). No one knows why.
Advanced nuclear magnetic resonance (NMR) techniques at the U.S. Department of Energy's Ames Laboratory have revealed surprising details about the structure of a key group of materials in nanotechology, mesoporous silica nanoparticles (MSNs), and the placement of their active chemical sites.
One of the most common causes of diarrhea worldwide - accounting for millions of cases and tens of thousands of deaths, mostly of small children - is the parasite Cryptosporidium. Doctors can treat children with Cryptosporidium for dehydration, but unlike many other causes of diarrhea, there are no drugs to kill the parasite or vaccines to prevent infection.
