In one of the first looks at the urinary virome, researchers find hundreds of viruses, most of which have never been sequenced before.
Millions of measurements from 23 people who consumed extra calories every day for a month reveal changes in proteins, metabolites, and gut microbiota that accompany shifts in body mass.
A new study identifies microorganisms residing in the human fallopian tubes and uterus, but some researchers are skeptical of the findings.
Vaginal birth leads to changes in the development of offsprings’ microbiomes not seen among mice born via C-section, which researchers suspect might contribute to the weight differences.
E. coli that make indoles protect older worms, flies, and mice from frailty.
The composition of the gut microbiota varies by time of year and is more diverse than that of industrialized groups.
A Northwestern University plague researcher has been charged with a brutal murder. Here’s what we know about him.
An oral mix of a pre- and probiotic can decrease deaths from the condition, according to the results of a large clinical trial conducted in rural India.
In tissue samples from rhesus macaques, researchers find the virus in the same immune-privileged sites where Ebola has been found to persist in humans.
Decreased oxygen levels could present hidden threat to marine species
Species living in coastal regions could face a significant future threat from reduced levels of oxygen in the marine environment, according to research published in Nature Scientific Reports.
New research solves the 60-year-old paleontological mystery of a 'phantom' dicynodont
A new study has re-discovered fossil collections from a 19th century hermit that validate 'phantom' fossil footprints collected in the 1950s showing dicynodonts coexisting with dinosaurs.
Stephen Hawking, best-known physicist of his time, has died
Stephen Hawking, whose brilliant mind ranged across time and space though his body was paralyzed by disease, died early Wednesday, a University of Cambridge spokesman said. He was 76 years old.
Why does a spinning egg stand up?
If a hard-boiled egg is spun fast enough on a table, it will slowly stand upright as it continues to spin. Although the spinning egg rises due to the force of friction between the egg and the table, the full explanation involves ...
Multifunctional metalens unlocks with light
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a flat optical component that is simultaneously a metalens, a microscope objective that can resolve details smaller ...
Astronomers discover galaxies spin like clockwork
Astronomers have discovered that all galaxies rotate once every billion years, no matter how big they are.
It's not only size, but scales that matter in some male moth antennae
Male moths have evolved intricate scale arrangements on their antennae to enhance detection of female sex pheromones, which allows them to keep their antennae small enough to maximise flying, new research suggests.
New study suggests galactic bulge emissions not due to dark matter
A team of researchers from the U.S., New Zealand, Australia and Germany has found evidence suggesting that a type of star formation near the center of the Milky Way is responsible for large gamma ray emissions, not dark matter. ...
Scientists help solve mystery of why comets emit X-rays
The mystery of why comets travelling through Space give off X-ray emissions has been solved thanks to new research undertaken by a team that included science staff from STFC's Central Laser Facility (CLF) and RAL Space.
Feeding wildlife can influence migration, spread of disease
Animal migration patterns are changing as humans alter the landscape, according to new research from the University of Georgia. Those changes can affect wildlife interactions with parasites-with potential impacts on public ...
Warm Arctic means colder, snowier winters in northeastern US, study says
Scientists from Rutgers University-New Brunswick and Atmospheric and Environmental Research (AER) have linked the frequency of extreme winter weather in the United States to Arctic temperatures.
Genetic study shows explosion of diversity in fish after end-Cretaceous mass extinction
A team of researchers from several institutions across the U.S. has found evidence suggesting that there was an explosion of diversity in fish after the end-Cretaceous mass extinction. In their paper published in the journal ...
Double or nothing—astronomers rethink quasar environment
Using Hyper Suprime-Cam (HSC) mounted on the Subaru Telescope, astronomers have identified nearly 200 "protoclusters," the progenitors of galaxy clusters, in the early universe, about 12 billion years ago, about ten times ...
Ultra-white coating modelled on beetle scales
Researchers have developed a super-thin, non-toxic, lightweight, edible ultra-white coating that could be used to make brighter paints and coatings, for use in the cosmetic, food or pharmaceutical industries.
Researchers bring the bling to improve implants
In a world first, Australian researchers have harnessed the power of diamonds in a breakthrough that could lead to radical improvements in the way human bodies accept biomedical implants.
Pterosaurs went out with a bang, not a whimper
Fossils of six new species of pterosaurs - giant flying reptiles that flew over the heads of the dinosaurs - have been discovered by a research team led by the Milner Centre for Evolution at the University of Bath, revealing ...
Compassion helped Neanderthals to survive, new study reveals
They have an unwarranted image as brutish and uncaring, but new research has revealed just how knowledgeable and effective Neanderthal healthcare was.
Infected 'zombie ants' face no discrimination from nest mates
Carpenter ants infected with a specialized parasitic fungus are not subjected to aggression or isolation from their nest mates, and they continue to share in the colony's food resources until they leave the nest for the last ...
World's largest cities depend on evaporated water from surrounding lands
Urbanization has taken billions of people from the rural countryside to urban centers, adding pressure to existing water resources. Many cities rely on renewable freshwater regularly refilled by precipitation, rather than ...
Earth may be approaching a carbon dioxide threshold for melting ice in the Arctic
It may not rank among the all-time greatest dramas, but the history of ice on Greenland has been a source of scientific controversy for more than a decade.
