Products like pharmaceuticals have to be synthesized to have molecules of only one 'handedness' to match the structure of biomolecules in human proteins. Catalysts currently used to accomplish this are problematic. New research is helping to bring the goal of a solid 'chiral' catalyst that can easily be separated from its products closer to reality.
A new study finds researchers may have been missing the mark on the diet of endangered snow leopards. The findings suggest the leopards have been consuming larger, not smaller, species, and underscores the importance of verifying, through DNA testing, what endangered species need to survive.
Alcohol-craving rats have provided researchers with a detailed look into the complicated genetic underpinnings of alcoholism.
A new technique gives biofuel-producing microbes the upper hand against unwanted invaders. The development could reduce the cost and environmental impact of producing liquid biofuels and biochemicals as alternatives to petroleum-based products.
An X-ray microscopy technique has given scientists the ability to image nanoscale changes inside lithium-ion battery particles as they charge and discharge. The real-time images provide a new way to learn how batteries work, and how to improve them.
Scientists have tracked the flight paths of a group of bumblebees throughout their entire lives to find out how they explore their environment and search for food.
Detailed structure of cell's garbage disposal unit reveals surprise in how it is targeted by cancer drugs
Cancer cells are more dependent on a cellular garbage disposal unit -- the proteasome -- than healthy cells, and cancer therapies take advantage of this dependency. Scientists have determined the proteasome's 3D structure in unprecedented detail and have deciphered the exact mechanism by which inhibitor drugs block the proteasome. Their surprising results will pave the way to develop more effective treatments.
Researchers have uncovered previously hidden sources of ocean pollution along more than 20 percent of America's coastlines. The study offers the first-ever map of underground drainage systems that connect fresh groundwater and seawater, and also pinpoints sites where drinking water is most vulnerable to saltwater intrusion now and in the future.
A ZIKV purified inactivated virus Zika vaccine candidate provided robust protection against the virus in rhesus monkeys in a new preclinical study. Findings support advancing the candidate to human trials.
Researchers have provided geological evidence for China's 'Great Flood,' a disastrous event on the Yellow River from which the Xia dynasty is thought to have been born. The flood occurred in roughly 1920 BC, they say, which is several centuries later than traditionally thought -- meaning the Xia dynasty, and its renowned Emperor Yu, likely had a later start than Chinese historians have thought, too.
Plant biologists have discovered how sunflowers use their internal circadian clock, acting on growth hormones, to follow the sun during the day as they grow. Following the sun allows the plants to grow faster and put on more biomass.
A group of physicists developed a way to use the therapeutic effect of heating or cooling the tissues due to the magnetocaloric effect.
You may have heard of plans to use drones for delivering packages, monitoring wildlife, or tracking storms. But painting murals? Researchers have enlisted tiny drones to create dot drawings -- an artistic technique known as stippling.
Researchers have developed a computer model that will aid in the design of nanocarriers, microscopic structures used to guide drugs to their targets in the body. The model better accounts for how the surfaces of different types of cells undulate due to thermal fluctuations, informing features of the nanocarriers that will help them stick to cells long enough to deliver their payloads.
Climate change is threatening to expose hazardous waste at an abandoned camp thought to be buried forever in the Greenland Ice Sheet, new research has found. Camp Century, a United States military base built within the Greenland ice sheet in 1959, doubled as a top-secret site for testing the feasibility of deploying nuclear missiles during the Cold War. When the camp was decommissioned in 1967, its infrastructure and waste were abandoned.
Elite and competitive swimmers log between 60,000 and 80,000 meters weekly -- swimming the length of an Olympic-sized pool 1,200 times -- which places significant stress on their shoulder joints.
A new study from Indiana University researchers shows that although most people who engage in sexting expect their messages to remain private, nearly one in four people are sharing the sexual messages they receive.
A new study reveals that those who affiliate with the Democratic Party have different views than those who vote Republican on the following issues: the likelihood of floods occurring, adopting protection measures, and expectations of disaster relief from the government.
All living toothed whales rely upon echoes of their own calls to navigate and hunt underwater, a skill that works best in conjunction with high-frequency hearing. Now, researchers who studied one of the best-preserved ears of any ancient whale ever discovered find that whales' high-frequency hearing abilities arose earlier than anticipated.
When it comes to personal finances, impulsiveness and materialism can lead to bad decisions and a failure to save enough, but new research suggests that when people focus more on the future, they tend to be less impulsive, regardless of their level of financial literacy.
