Once female elk reach the age of about 10 years, they are nearly invulnerable to human hunters. This age-related difference could be driven only by selection by hunters — or

Antibiotic design strategy boosts odds against resistance development
The technique, which has been validated against a drug-resistant bacterial strain, identifies compounds that target two or more receptor sites on proteins that inhibit a key cellular function. To obtain
Search for Earth-like planets: Try a statistical approach
“The nature of proof should not be: ‘Can we point at a planet and say, yes or no, that’s the planet hosting alien life,” said Jacob Bean, associate professor of
Low-mass stars always born with a sibling: Many, like our sun, split up
Almost certainly yes — though not an identical twin. And so did every other sunlike star in the universe, according to a new analysis by a theoretical physicist from the
Solar material for producing clean hydrogen fuel
Global climate change and the energy crisis mean that alternatives to fossil fuels are urgently needed. Among the cleanest low-carbon fuels is hydrogen, which can react with oxygen to release
Extraction of phenols from grape skin, seeds, optimized
The research group ‘Food Colour and Quality’, which is part of the Faculty of Pharmacy at the University of Seville, has published two scientific articles in which the reason that
Ancient otter tooth found in Mexico suggests mammals migrated across America
Tseng, PhD, assistant professor in the Department of Pathology and Anatomical Sciences in the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo, was on the dig
Graphene transistor could mean computers that are 1,000 times faster
Ryan M. Gelfand, an assistant professor in CREOL, The College of Optics Photonics, was a graduate student at Northwestern University when he began researching the concept with fellow grad student
E. coli bacteria’s defense secret revealed
When undesirable molecules show up, the bacterial cell opens a tunnel though its cell wall and “effluxes,” or pumps out, the intruders. “Dynamic assembly of these tunnels has long been
Magnets, all the way down!
It turns out that assemblies of metallic nanoparticles, which can be carefully arranged at multiple length scales, behave like bulk magnets and display intriguing, shape-dependent behavior. The effects, reported this
Seaweed derivative could be just what lithium-sulfur batteries need
In research led by Gao Liu, the team unexpectedly found that carrageenan, a seaweed derivative, acts as a stabilizer in lithium-sulfur batteries. Better stability allows for more cycling and an
New insight into galaxy cluster’s spectacular ‘mini-halo’
The scientists studied a cluster of thousands of galaxies more than 250 million light-years from Earth, named the Perseus Cluster after the constellation in which it appears. Embedded within the
Genetic variants linked to higher BMI may be protective against Parkinson disease
The researchers used a Mendelian randomization approach to examine whether genetic variants linked to higher BMI were also associated with risk of Parkinson disease. The associations between the genetic variants
US aid to combat malaria in Africa is associated with reduced risk of childhood mortality
These 19 PMI countries along with 13 others in sub-Saharan Africa that did not receive PMI funding presented the authors with a “quasi-experiment” that enabled them to analyze large population-representative
Makeup of vaginal microbiome linked to preterm birth
In a study of predominantly African-American women — who have a much higher rate of delivering babies early compared with other racial groups — researchers at Washington University School of
