“We have found a new trigger to explain the start-up of the Atlantic current system during the greenhouse-icehouse climate transition: During the warm climate, buoyant fresh water flooded out of the Arctic and prevented the ocean-sinking that helps power the conveyor. We found that the Arctic-Atlantic gateway closed due to tectonic forces, causing a dramatic … Read more
Researchers at the Paul Scherrer Institute PSI have developed a new method with which strong magnetic fields can be precisely measured. They use neutrons obtained from the SINQ spallation source. In the future, it will therefore be possible to measure the fields of magnets that are already installed in devices and thus are inaccessible by … Read more
Neurons communicate with each other by sending out rapid pulses of electrical signals called spikes. At first glance, the generation of these spikes can be very reliable: when an isolated neuron is repeatedly given exactly the same electrical input, we find the same pattern of spikes. Why, then, does the activity of cortical neurons in … Read more
Life over the last half century has been pretty good for populations of Svalbard barnacle geese. A hunting ban implemented in the 1950s in their overwintering area in Scotland has led to explosive population growth – from roughly 2800 birds in 1960 to more than 40000 birds today. But what will happen to these birds … Read more
If you’ve never seen a horseshoe bat, you’re missing out. Their comically large ears are only rivaled for wackiest feature by their nose leaves, little flaps of skin that spread outward from their faces like petals. If you grew up with siblings who would say, “That’s you,” when they saw an ugly creature on TV, … Read more
Scientific papers go through a peer-review process before they are accepted for publication in a journal. They are sent to two or more independent researchers for comment. Those researchers are asked to assess the robustness of the methods used and the conclusions drawn, as well as the novelty of the study. The reviewers’ comments play … Read more
Scientists have combined analyses from honey and salmon to show how lead from natural and industrial sources gets distributed throughout the environment. By analysing the relative presence of differing lead isotopes in honey and Pacific salmon, Vancouver-based scientists have been able to trace the sources of lead (and other metals) throughout the region. Scientists in … Read more
Mount Sinai researchers have found a new type of therapy to be effective for patients with a particular type of bone marrow cancer that is resistant to several standard therapies, according to results of a clinical trial published in The New England Journal of Medicine in August. This trial tested selinexor with dexamethasone, a combination that significantly … Read more
A research team led by the University of California San Diego has discovered the root cause of why lithium metal batteries fail–bits of lithium metal deposits break off from the surface of the anode during discharging and are trapped as “dead” or inactive lithium that the battery can no longer access. The discovery, published Aug. … Read more
Online hate thrives globally through self-organized, scalable clusters that interconnect to form resilient networks spread across multiple social media platforms, countries and languages, according to new research published today in the journal Nature. Researchers at the George Washington University developed a mapping model, the first of its kind, to track how these online hate clusters … Read more
