Rolling out next-gen nanocars

Researchers continue to advance the science of single-molecule machines with a new lineup of nanocars, in anticipation of the next international Nanocar Race in 2022.

US corn crop's growing sensitivity to drought revealed

New management approaches and technology have allowed the US. Corn Belt to increase yields despite some changes in climate. However, soil sensitivity to drought has increased significantly, according to a new study that could help identify ways to reverse the trend.

Time-keeping brain protein influences memory

Upsetting the brain's timekeeping can cause cognitive impairments, like when jetlag makes you feel foggy and forgetful. These impairments may stem from disrupting a protein that aligns the brain's time-keeping mechanism to the correct time of day, according to new research in fruit flies.

SOFIA discovers water on sunlit surface of moon

NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.

Researcher found female candidates are more likely to discuss the economy than males

In a new study published in Politics & Policy, Deserai Crow, Ph.D., associate professor at the University of Colorado Denver in the School of Public Affairs, found significant differences in rhetoric between both party affiliation and gender. Narratives from both Republican and Democratic candidates in 48 U.S. House campaigns from the 2018 midterm election were analyzed in this study.

Hidden losses deep in the Amazon rainforest

Few places on Earth are as rich in biodiversity and removed from human influence as the world's largest rainforest—the Amazon. Scientists at Louisiana State University (LSU) have been conducting research within the pristine rainforest for decades. However, they began to notice that some of the animals, specifically birds that forage on and near the forest floor, had become very difficult to...

Aged cell variations may control health and onset of age-related diseases

Researchers from Kumamoto University, Japan have proposed that cellular senescence variations during the aging process could lead to control of health and onset of age-related diseases. Based on the characteristics of the secretion of inflammatory cytokines released by aged cells, they hypothesize that there are at least four distinct states of cellular senescence, and that these four states arise...

Land management in forest and grasslands: How much can we intensify?

Intensive land-use reduces beneficial effects of biodiversity on ecosystem services. This is the main result of a study led by the Helmholtz Centre for Environmental Research (UFZ), the German Centre for Integrative Biodiversity Research (iDiv) and the University of Bern. It assessed the effects of land management on the links between biodiversity, ecosystem functions and ecosystem services,...

Light on efficiency loss in organic solar cells

Insight into energy losses that affect the conversion of light into electricity could help enhance organic solar cell efficiencies. A KAUST-led team of organic chemists, materials engineers, spectroscopists and theoretical physicists from six research groups has extensively evaluated efficiency-limiting processes in organic photovoltaic systems.

Timeline of early eukaryotic evolution unveiled

By analyzing duplicates of thousands of genes, researchers have reconstructed the evolutionary events leading to the creation of eukaryotic cells, the precursors to virtually all life you can see with the naked eye. The evolutionary timeline from simple bacterial cells to complex eukaryotic cells progressed differently than previously thought. The study, a collaboration between the Comparative...

NASA's SOFIA discovers water on sunlit surface of Moon

NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.

Scientists remove 98 'murder hornets' in Washington state

Scientists removed 98 so-called murder hornets from a nest discovered near the Canadian border in Washington state over the weekend, including 13 that were captured live in a net, the state Department of Agriculture said Monday. The other 85 Asian giant hornets were vacuumed into a special container when the first nest discovered on U.S. soil was eradicated on Saturday, the agency...
