Growing sweet corn at higher densities doesn't increase root lodging risk Sweet corn growers and processors could be bringing in more profits by exploiting natural density tolerance traits in certain hybrids. That's according to 2019 research from USDA Agricultural Research Service (ARS) and University of Illinois scientists.
Study may help boost peptide design Peptides, which are short strings of amino acids, play a vital role in health and industry with a huge range of medical uses including in antibiotics, anti-inflammatory and anti-cancer drugs. They are also used in the cosmetics industry and for enhancing athletic performance. Altering the structure of natural peptides to produce improved compounds is therefore of great interest to scientists and industry. But how the machineries that produce these peptides work still isn't clearly understood.
Time running out to save coral reefs New research on the growth rates of coral reefs shows there is still a window of opportunity to save the world's coral reefs—but time is running out.
Ocean-bottom sediments tell a story about ancient Greenland summers Over hundreds of thousands of years, sediments from southern Greenland have been making their way into the ocean, where they're carried by underwater currents to a location in the Labrador Sea called the Eirik Drift.
Animal production responsible for vast majority of air quality-related health impacts from US food Poor air quality caused by food production in the United States is estimated to result in 16,000 deaths annually, 80 percent of which are related to animal production, according to a new study led by researchers at the University of Minnesota. The research also found there are measures farmers and consumers alike can take to reduce the air quality-related health impacts of the food we eat.
Researchers reconstruct the oral microbiomes of Neanderthals, primates, and humans Living in and on our bodies are trillions of microbial cells belonging to thousands of bacterial species, known as the microbiome. These microbes play key roles in human health, but little is known about their evolution. In a new study published in the Proceedings of the National Academy of Sciences, a multidisciplinary international research team led by scientists at the Max Planck Institute for the Science of Human History (MPI-SHH) investigated the evolutionary history of the hominid oral microbiome by analyzing the fossilized dental plaque of humans and Neanderthals spanning the past 100,000 years and comparing it to those of wild chimpanzees, gorillas, and howler monkeys.
Video: Active Particles Crystalize
Author(s): David Ehrenstein
Under the right conditions, self-propelled particles collectively transition from a state of liquid-gas coexistence to one where the particles can crystalize, according to simulations.

Measuring time accurately increases the entropy in the universe A clock with controllable accuracy has shown that the better a clock is at timekeeping, the more entropy it will produce in the form of heat, increasing disorder as it ticks
Physicists have measured an atom's 'neutron skin' for the first time Physicists have measured the "neutron skin" of an atom for the first time, and perhaps unsurprisingly, it is extremely thin. The measurement may help us understand the properties of neutron stars
Research News: Black Holes Studied as a Population
