The sharks live in deep waters and are thought to use light as a form of camouflage.
A former conservation officer who made international headlines in 2015 for refusing to kill two orphaned bear cubs is suing to get his job back and his lost pay...
Scientists regularly use remote sensing drones and satellites to record how climate change affects permafrost thaw rates—methods that work well in barren tundra landscapes where there's nothing to obstruct the view.
It’s awfully hard to find any upside in a global pandemic that’s sickened nearly 115 million people and killed more than 2.5 million. But throughout 2020, there was some good news buried in the bad concerning that other great infirmity: the sickly state of the earthly climate. When economies are booming and people are moving, greenhouse gasses soar. It follows then that economic...
The rush for scientific understanding of the novel coronavirus has focused on biological mechanisms: how people get infected, the response of the human body, and the fastest path to a vaccine. As an aerosol scientist, Tami Bond went a different route, convening a research team that would treat the virus like any other aerosol. This team set out to quantify the dynamics of how aerosols like viruses...
Researchers have identified a new drug that could prevent AD by modulating, rather than inhibiting, a key enzyme involved in forming amyloid plaques.
When quantum computers become more powerful and widespread, they will need a robust quantum internet to communicate. Engineers have addressed an issue barring the development of quantum networks that are big enough to reliably support more than a handful of users.
Researchers have developed a remote sensing method of measuring the depth of permafrost by analyzing vegetation cover in boreal ecosystems.
Advanced Research & Innovation Agency will be exempt from existing procurement rules for ‘maximum flexibility’, says governmentA new £800m government science and defence research agency will be exempt from existing procurement rules, prompting warnings from Labour that it could be used as “cover for cronyism”.Originally the brainchild of Dominic Cummings, the Advanced Research &...
In the private space industry, it can seem that there’s SpaceX and then there’s everyone else. Only Blue Origin, backed by its own billionaire founder in the person of Jeff Bezos, seems able to command the same degree of attention. And Blue Origin hasn’t even gone beyond suborbital space yet. Rocket Lab might soon have something to say about that duopoly. The company, founded...
Today, we can say without a shadow of doubt that an alternative to fossil fuels is needed. Fossil fuels are not only non-renewable sources of energy but also among the leading causes of global warming and air pollution. Thus, many scientists worldwide have their hopes placed on what they regard as the fuel of tomorrow: hydrogen (H2). Although H2 is a clean fuel with incredibly high energy density,...
Powerful insecticides are turning up in deer in nearly every corner of Minnesota, raising concerns that the ubiquitous chemicals may be keeping fawns from surviving to maturity or harming deer reproduction.
The coronavirus pandemic has drawn new attention to the digital divide, as the need for online schooling and working from home has disproportionately hurt those without computer equipment and skills. New research finds that people with basic Information Technology (IT) skills are more likely to be employed, even in jobs that aren't explicitly tied to those skills.
High-resolution imaging and 3D computer modeling show that the dendrites of neurons weave through space in a way that balances their need to connect to other neurons with the costs of doing so. The discovery emerged as researchers sought to understand the fractal nature of neurons as part of a project to design fractal-shaped electrodes to connect with retinal neurons to address vision loss due to...
Health impacts from a 2010 spill are found even in dolphins born years later.
A new method to rate tornado warnings shows that nighttime tornadoes in the U.S. have a lower probability of detection and a higher false-alarm rate than other events. Summertime tornadoes, occurring in June, July or August, also are more likely to evade warning.
A new study has shown that gentle streams of water carrying sound and microscopic air bubbles can clean bacteria from salad leaves more effectively than current washing methods used by suppliers and consumers. As well as reducing food poisoning, the findings could reduce food waste and have implications for the growing threat of anti-microbial resistance.
Researchers exploring the interactions between light particles, photons and matter find that optical microresonators host quasiparticles made by two photons.
Earthquakes in the Black Rock Desert are rare and capturing the seismic recordings from these earthquakes provides a glimpse into the volcanic system of the Black Rock Desert that, while not showing any signs of erupting, is still active.
Positive psychological effects associated with taking small doses of psychedelic drugs are likely the result of users' expectations, suggests a new study.
Lithium metal batteries have higher charge density than conventional lithium ion batteries but are prone to problems of tree-like metal dendrites, which can cause short circuits or explosions. A new article shows that flowing ions near the cathode can prevent this problem.
Researchers have identified a potential new marker that shows cardiovascular disease may be present in a patient using an optical coherence tomography (OCT) scan -- a non-invasive diagnostic tool commonly used in ophthalmology and optometry clinics to create images of the retina. The finding suggests it may be possible to detect heart disease during an eye examination.
Disruptions in the circadian rhythms in lung cells may explain why adults who survived premature birth are often more at risk of severe influenza infections, suggests a new study.
