New research from The University of Texas at Austin has explained an important mystery about natural gas hydrate formations and, in doing so, advanced scientists' understanding of how gas hydrates could contribute to climate change and energy security.
The research used a computer model of gas bubbles flowing through hydrate deposits, a common phenomenon which according to existing models, should not be possible based on physics. The new model helps explain how some deposits grow into massive natural gas hydrate reservoirs, such as those found beneath the Gulf of Mexico.
As oceans absorb more carbon dioxide, they are becoming increasingly acidic and shifting the delicate balance that supports marine life. How species will cope with ocean acidification and the other consequences of global climate change is still very much unknown and could have sweeping consequences.
Researchers from the University of Washington School of Aquatic and Fishery Sciences have discovered that ocean acidification impacts the ability of some oysters to pass down "memories" of environmental trauma to their offspring.
Groups of western gorillas may defend the centres of their home ranges against neighbouring groups, a study in Scientific Reports suggests. These findings may suggest that western gorillas are territorial.
Gorillas are widely assumed to be non-territorial due to their large home ranges (the areas in which they live and move), extensive overlap between the home ranges of different groups, and limited aggression between groups.
URBANA, Ill. - Like most invasive species, when the soybean aphid arrived in the Midwest in 2000, it brought none of its natural enemies along for the ride. So, naturally, finding itself in the soybean capital of the world, the tiny insect went bonkers. Taking advantage of a nifty ability to reproduce without mating, populations exploded and the soybean aphid quickly became the number one insect pest affecting the crop.
NASA's Terra satellite passed over the Southern Indian Ocean and provided forecasters with a visible image of Ex-Tropical Cyclone 21S. Although no longer a tropical cyclone, the system has triggered warnings for heavy rainfall and winds.
Tropical cyclone 21S was along the Pilbara coast. The Pilbara Coast is also known as the northwest coast of Western Australia.
Person-to-person transmission of SARS-CoV-2 occurred between two people with prolonged, unprotected exposure while the first patient was symptomatic. Despite active monitoring and testing of 372 contacts of both cases, no further transmission was detected
Commercial fast-charging stations subject electric car batteries to high temperatures and high resistance that can cause them to crack, leak, and lose their storage capacity, write engineers at the University of California, Riverside in a new study published in Energy Storage. To remedy this, the researchers have developed a method for charging at lower temperatures with less risk of catastrophic damage and loss of storage capacity.
A room-temperature bonding technique for integrating wide bandgap materials such as gallium nitride (GaN) with thermally-conducting materials such as diamond could boost the cooling effect on GaN devices and facilitate better performance through higher power levels, longer device lifetime, improved reliability and reduced manufacturing costs. The technique could have applications for wireless transmitters, radars, satellite equipment and other high-power and high-frequency electronic devices.
HOUSTON - (March 12, 2020) - It's not enough to take antibiotic-resistant bacteria out of wastewater to eliminate the risks they pose to society. The bits they leave behind have to be destroyed as well.
Researchers at Rice University's Brown School of Engineering have a new strategy for "trapping and zapping" antibiotic resistant genes, the pieces of bacteria that, even though theirs hosts are dead, can find their way into and boost the resistance of other bacteria.
With outbreaks of infectious diseases making headlines around the world, scientists are under pressure to understand the drivers that influence the transmission of pathogens in order to better predict and control disease outbreaks.
A new research study led by Professor Kathleen Alexander of the College of Natural Resources and Environment explores the ways that landscapes can influence animal behavior, fostering dynamics that either encourage or limit the spread of infectious diseases.
Researchers at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan have identified a new mechanism that helps animals to develop with precise and constant form.
PLYMOUTH MEETING, PA [March 12, 2020] -- New research from the American Cancer Society in the March 2020 issue of JNCCN--Journal of the National Comprehensive Cancer Network finds that younger cancer survivors are more likely to experience significant financial strain for daily living necessities, such as food, housing, and monthly bills, even years after diagnosis. Among survivors between ages 18 and 39, 20.4% expressed high levels of worry about paying monthly bills compared to 12.9% of individuals without a history of cancer.
Colloidal quantum dot (CQD) solar cells have attracted considerable attention due to the advantages of being flexible and lightweight. Besides, they are much easier to manufacture, compared with that of commercial silicon solar cells in use today. A novel technology, capable of maximizing the performance of the existing CQD solar cells has been developed, recently.
Nanoengineers at the University of California San Diego developed a safety feature that prevents lithium metal batteries from rapidly heating up and catching fire in case of an internal short circuit.
The team made a clever tweak to the part of the battery called the separator, which serves as a barrier between the anode and cathode, so that it slows down the flow of energy (and thus heat) that builds up inside the battery when it short circuits.
The group headed by Dr. Julia Brailovskaia published their results in the journal "Computers in Human Behavior" from 6. March 2020.
