Japanese researchers have succeeded in catalytic asymmetric iodoesterification from simple alkene substrates and carboxylic acids. Published in Angewandte Chemie International Edition on April 27, this new research, was accomplished by precisely controlling multiple interactions in a single catalytic reaction. This synthetic reaction is expected to contribute to the simplification of industrial processes and greater efficiency in optical active drug production.
It's "hammerhead" time according aerial drone footage of blacktip sharks fleeing to shallow waters when confronted by a huge predator along the coast of southeast Florida. Footage from the drone provides the first evidence of adult blacktip sharks (Carcharhinus limbatus) using shallow waters as a refuge from the great hammerhead shark, (Sphyrna mokarran) - proving you "can't touch this."
SASKATOON - An innovative radiation treatment that could one day be a valuable addition to conventional radiation therapy for inoperable brain and spinal tumors is a step closer, thanks to new research led by University of Saskatchewan (USask) researchers at the Canadian Light Source (CLS).
Air pollution in China has received great attention due to its effects on climate and human health. A recent study showed the contrasting variation of air pollutants in China using long-term comprehensive data sets from 2013 to 2017, during which Chinese government took major efforts to reduce anthropogenic emission in polluted regions. A significant decreasing trend in the PM2.5 concentration in heavily polluted regions of the eastern China was happening. As a consequence, the heavily polluted days decreased in corresponded regions.
New research led by scientists from Newcastle University and the University of Nottingham has shown that typical teenage behaviour doesn't just occur in young humans - it happens in dogs too.
The study, headed by Dr Lucy Asher from Newcastle University, is the first to find evidence of adolescent behaviour in dogs.
COVID-19's rapid spread throughout the world has been fueled in part by the virus' ability to be transmitted by people who are not showing symptoms of infection.
Now, a study by researchers at Princeton has found that this silent phase of transmission can be a successful evolutionary strategy for pathogens such as viruses like the one that causes COVID-19. The study was published May 8 in the journal Proceedings of the National Academy of Sciences.
RICHMOND, Va. (May 12, 2020) -- Psychopathy is widely recognized as a risk factor for violent behavior, but many psychopathic individuals refrain from antisocial or criminal acts. Understanding what leads these psychopaths to be "successful" has been a mystery.
A new study conducted by researchers at Virginia Commonwealth University sheds light on the mechanisms underlying the formation of this "successful" phenotype.
New imaging technology allows scientists to see the widespread loss of brain synapses in early stages of Alzheimer's disease, a finding that one day may help aid in drug development, according to a new Yale University study.
COVID-19, the disease caused by coronavirus SARS-Cov-2, has infected over 4 million people in 212 countries, of whom at least 272,000 have died. The ongoing economic and social impact of the pandemic is staggering, but despite a daily flood of news on the disease, few laypeople know that paradoxically, COVID-19 mostly kills through an overreaction of the immune system, whose function is precisely to fight infections.
Blockchain, the technology that underpins digital currency and has acquired a slightly tainted reputation as a useful tool for organised crime, is coming out of the shadows and is set to become a friend to consumers, protecting them from tainted food, fake medicine, fraud and products with illegal or unethical origins, a new study from the University of Bath shows.
To some, farming might seem simple: plant seeds, help them grow, then sell the product. But the reality is much different. Farming requires many complex decisions throughout the year.
One such decision is seeding rate - the number of seeds planted per acre. The best seeding rate for soybean fields is one of the most debated topics for those involved in agriculture.
Researchers at Orygen and La Trobe University in Melbourne, Australia have completed a rapid review of contemporary epidemic and pandemic research to assess the potential impact of COVID-19 on people with psychosis.
A group of tiny RNA that should attack the virus causing COVID-19 when it tries to infect the body are diminished with age and chronic health problems, a decrease that likely helps explain why older individuals and those with preexisting medical conditions are vulnerable populations, investigators report.
What The Study Did: Claims data for nearly 200,000 Medicare patients were used to examine the association between starting pulmonary rehabilitation within 90 days of being hospitalized for chronic obstructive pulmonary disease (COPD) and survival after one year. Pulmonary rehabilitation involves exercise training and self-management education.

What would you do if the person standing next to you would suddenly scream and run away? Would you be able to carry on calmly with what you're doing, or would you panic? Unless you're James Bond, you're most likely to go for the second option: panic.
But now imagine another scenario: while out on the street, the person walking in front of you suddenly freezes: she stops moving and becomes perfectly still. What would you do?
