Phys.org / How bacteria exploit human cell metabolism to sharpen infections and potentially evade treatment
A research team at the University of Greifswald's Research Training Group RTG-PRO "Proteases in pathogen and host: importance in infection and inflammation" has discovered a new mechanism by which bacterial pathogens adjust ...
Phys.org / Powerful UFO spotted blasting from a distant black hole
Astronomers have detected one of the most powerful ultra-fast outflows ever seen from a distant supermassive black hole. Using XMM-Newton and NuSTAR, a team studied a hyper-luminous quasar at cosmic noon and found two distinct ...
Phys.org / Third time's the charm for a row of faint galaxies without dark matter
A Yale-led team of astronomers has found a third galaxy devoid of dark matter—located alongside the other two in a formation that has never been seen before. Astronomers have followed a faint, cosmic trail of gas to a third ...
Phys.org / Could Earth have sent life to Jupiter's moon Europa?
Could Earth have seeded Jupiter's moon Europa with bacterial life, where it could have taken hold in Europa's ocean and perhaps evolved into something more? That's the hypothesis of a new paper in the International Journal ...
Phys.org / 'Geriatric' butterfly species lives nearly three times as long as their relatives
A tropical butterfly has evolved an ingenious anti-aging strategy by delaying the aging process, enabling it to live far longer than its closest relatives, according to a new University of Bristol-led study published in Nature ...
Phys.org / Deep learning helps discover hundreds of Antarctic earthquakes coming from an unlikely location
Most of the earthquakes we hear about are due to tectonic plates colliding or sliding past each other near plate boundaries. Yet researchers have detected some enigmatic earthquakes happening inside the more stable interiors ...
Phys.org / Super El Niños may lose their punch in a warming world
In a strong El Niño winter, normally dry regions can suddenly drown in rain. NASA notes that "typically dry regions can experience nearly two times as much rain during a strong El Niño." Indeed, the blockbuster El Niños of ...
Phys.org / Dolphins know how to avoid troublesome males by listening for their 'names'
When female bottlenose dolphins want to avoid males known for pushy mating behaviors, they listen out for their unique signature whistles. That's the suggestion of a study published in Proceedings of the National Academy ...
Phys.org / Young disk around WRAY 15-1880 may contain a primitive planetary system
Italian astronomers have used the Very Large Telescope (VLT) to perform polarimetric observations of the star WRAY 15-1880 and its young circumstellar disk. Results of the new observations, presented June 10 on the arXiv ...
Phys.org / When glaciers vanish, so does the hidden life they support
We often hear about glacier melting and predictions of what climate change could do. But very little is mentioned about the effects on ecosystems or the animals that call them home. To redress some of this imbalance, an international ...
Phys.org / Radiocarbon dating confirms 10,000 years of continuous human occupation in the Pyrenees
Researchers from the Universitat Autònoma de Barcelona (UAB) have created an open database with 124 carbon-14-dated samples that have made it possible to construct the chronological sequence of 380 sites located in the Aigüestortes ...
Phys.org / Physicists identify upper limit to resistivity in a pure metal
Experimental atomic physicists have discovered there is a maximum amount of electrical resistance, or resistivity, that can result from collisions between electrons.
