More ships and more clouds mean cooling in the arctic

With sea ice in the Arctic melting at an alarming rate, opportunities for trans-Arctic shipping are opening up, and by mid-century ships will be able to sail right over the North Pole — something not previously possible for humankind. UConn geographer Scott Stephenson and colleagues say the growth of trans-Arctic ... Read More »

We are predisposed to forgive, new research suggests

When assessing the moral character of others, people cling to good impressions but readily adjust their opinions about those who have behaved badly, according to new research. This flexibility in judging transgressors might help explain both how humans forgive — and why they sometimes stay in bad relationships, said the ... Read More »

Multi-joint, personalized soft exosuit breaks new ground

In the future, smart textile-based soft robotic exosuits could be worn by soldiers, fire fighters and rescue workers to help them traverse difficult terrain and arrive fresh at their destinations so that they can perform their respective tasks more effectively. They could also become a powerful means to enhance mobility ... Read More »

Witnessing violence in high school as bad as being bullied

Students who witness violence in school at age 13 are at later risk of psycho-social and academic impairment at age 15, according to a new longitudinal study by researchers at Université de Montréal with colleagues in Belgium and France. In the study, published today in the Journal of Epidemiology and ... Read More »

Organic farming methods favors pollinators

Pollinating insects are endangered globally, with a particularly steep decline over the last 40 years. An extensive 3-year study from Lund University in Sweden has found that organic farming methods can contribute to halting the pollinator decline. This beneficial effect is due to both the absence of insecticides and a ... Read More »

Geologists reveal ancient connection between England and France

The British mainland was formed from the collision of not two, but three ancient continental land masses, according to new research. Scientists have for centuries believed that England, Wales and Scotland were created by the merger of Avalonia and Laurentia more than 400 million years ago. However, geologists based at ...

New genetics tool helps answer evolutionary questions

The age of big data is here. Thanks to innovations in genetic sequencing technology, scientists can now generate massive datasets describing the genomes of Earth’s diverse set of species. This ever-growing genomic encyclopedia has the capacity to reveal the forces shaping complex patterns of genetic variation between individuals, populations and ... Read More »

Famous theory of the living Earth upgraded to ‘Gaia 2.0’

A time-honoured theory into why conditions on Earth have remained stable enough for life to evolve over billions of years has been given a new, innovative twist. For around half a century, the ‘Gaia’ hypothesis has provided a unique way of understanding how life has persisted on Earth. It champions ... Read More »

Novel flying robot mimics rapid insect flight

A novel insect-inspired flying robot, developed by TU Delft researchers from the Micro Air Vehicle Laboratory (MAVLab), is presented in Science (14 September 2018). Experiments with this first autonomous, free-flying and agile flapping-wing robot — carried out in collaboration with Wageningen University & Research — improved our understanding of how ...

Eyes have a natural version of night vision

To see under starlight and moonlight, the retina of the eye changes both the software and hardware of its light-sensing cells to create a kind of night vision. Retinal circuits that were thought to be unchanging and programmed for specific tasks are adaptable to different light conditions, say the Duke ... Read More »

New means to fight ‘un-killable’ bacteria in healthcare settings

Scientists at the Research Institute of the McGill University Health Centre (RI-MUHC) have identified new means of fighting drug-tolerant bacteria, a growing global threat as menacing as drug-resistant microbes. Little is known about the mechanisms leading to tolerance, a strategy that makes bacteria “indifferent” to antibiotics and almost “un-killable,” which ... Read More »

Appetite for shark fin soup serious risk to threatened sharks

Fishing pressure on threatened shark populations has increased dramatically in recent years and it is urgent that consumers reject shark fin products altogether — a study in Marine Policy by researchers from the Swire Institute of Marine Science (SWIMS), School of Biological Sciences, University of Hong Kong (HKU), the Sea ...
