Owning a dog is influenced by genetic make-up

A team of Swedish and British scientists have studied the heritability of dog ownership using information from 35,035 twin pairs from the Swedish Twin Registry. The new study suggests that genetic variation explains more …

Climate a driver of language diversity

A region’s climate has a greater impact than landscape on how many languages are spoken there, new research from The Australian National University (ANU) shows.

Record-shattering underwater sound

A team of researchers has produced a record-shattering underwater sound with an intensity that eclipses that of a rocket launch. The intensity was equivalent to directing the electrical power of an entire city onto a single …

Virtual reality game simulates experiences with race

Video games that use virtual reality to create immersive experiences have become increasingly popular for entertainment and for research. However, the representation of race in these simulations is often shallow—and fails …

Ernst Haeckel: Pioneer of modern science

“By ecology, we understand the whole science of the organism’s relationship with the surrounding outside world, which includes in a broader sense all ‘existential conditions’. These are partly organic and partly inorganic …

Making the best of sparse information

New findings reported by LMU researchers challenge a generally accepted model of echolocation in bats. They demonstrate that bats require far less spatial information than previously thought to navigate effectively.

Mission control ‘saves science’

Every minute, ESA’s Earth observation satellites gather dozens of gigabytes of data about our planet—enough information to fill the pages on a 100-metre long bookshelf. Flying in low-Earth orbits, these spacecraft are continuously …

Healthcare, social media and a web of moral issues

“Ethics asks what we owe to one another and how we should treat one another. The internet has changed the landscape in which we, as humans, relate, and ethicists need to keep pace,” explains Assistant Professor of Philosophy …

Engineered microbial production of grape flavoring

Researchers report a microbial method for producing an artificial grape flavor. Methyl anthranilate (MANT) is a common grape flavoring and odorant compound currently produced through a petroleum-based process that uses large …

Single molecule magnet used as a scanning magnetometer

A team of researchers from the University of California and Fudan University has developed a way to use a single molecule magnet as a scanning magnetometer. In their paper published in the journal Science, the group outlines …

How one fern can soak up so much arsenic—and not die

Arsenic-contaminated soil and groundwater pose risks to millions of Americans and hundreds of millions of people worldwide. Cleaning up the toxic metal is a laborious and expensive process, with some remediations of arsenic …
