Shift in atmospheric rivers could affect Antarctic sea ice, glaciers

Weather systems responsible for transporting moisture from the tropics to temperate regions in the Southern Hemisphere have been gradually shifting toward the South Pole for the past 40 years, a trend which could lead to increased rates of ice melt in Antarct

Newfound ability to change baby brain activity could lead to rehabilitation for injured brains

Researchers have identified the brain activity for the first time in a newborn baby when they are learning an association between different types of sensory experiences. Using advanced MRI scanning techniques and robotics, the researchers found that a baby's

What do slight arm movements reveal about our breathing and health?

Special activity trackers can be used to fairly accurately determine the respiratory rate of people while they sleep. In the future, activity trackers could be used to detect the early stages of a disease, as a person's respiratory rate can indicate signs of

Scientists' atomic resolution protein models reveal new details about protein binding

Atom-scale models of proteins that incorporate ligands, like drug molecules, shows a strong correlation between minimally frustrated binding sites and drug specificity. Such models could lead to better-designed drugs with fewer side effects.

Identical evolution of isolated organisms

Palaeontologists have provided new proof of parallel evolution: conodonts, early vertebrates from the Permian period, adapted to new habitats in almost identical ways despite living in different geographical regions. The researchers were able to prove that th

Coppery titi monkeys do not deceive their partners

Since methods for genetic paternity analyses were introduced it became clear that many pair-living animal species, including humans, do not take partnership fidelity that seriously. In most species there is some proportion of offspring that is not sired by th

Magnetic brain waves to detect injury and disease

Researchers have designed a new Optically Pumped Magnetometer (OPM) sensor for magnetoencephalography (MEG). The sensor is smaller and more robust in detecting magnetic brain signals and distinguishing them from background noise than existing sensors. Benchma
