Microscopy technique enables 3D super-resolution nanometer-scale imaging

(University of Göttingen) Over the last two decades, microscopy has seen unprecedented advances in speed and resolution. However, cellular structures are essentially three-dimensional, and conventional super-resolution techniques often lack the necessary resolution in all three directions to capture details at a nanometer scale. A research team led by Göttingen University, including the University of Würzburg and the Center for Cancer Research in the U.S., investigated a super-resolution imaging technique that involves combining the advantages of...

Whole baby mammoth discovered by Yukon gold miners

A whole baby woolly mammoth has been found frozen in the permafrost of north-western Canada – the first such discovery in North America. The mummified ice-age mammoth is thought to be more than 30,000 years old. It was found by gold miners in Yukon's Klondike region on Tuesday. The area of the find belongs to the Tr'ondek Hwech'in First Nation. The Yukon government compared it to Russia's discovery of a baby mammoth in the permafrost of Siberia...

U.S. Supreme Court strikes down Roe v Wade decision

Millions of women in the U.S. will lose the legal right to abortion, after the Supreme Court overturned a 50-year-old ruling that legalized it nationwide. The court struck down the landmark Roe v Wade decision, weeks after an unprecedented leaked document suggested it favoured doing so. The judgement will transform abortion rights in the U.S., with individual states now able to ban the procedure. Half of the 50 states are expected to introduce new restrictions or bans. Thirteen...

Two killed as Nio electric car falls from third-floor office in Shanghai

Chinese electric carmaker Nio says that two people were killed when one of its vehicles fell from the third floor of its headquarters in Shanghai. One staff member and a person from a partner company died in the crash, the BBC reports. The incident took place on Wednesday at about 17:20 local time, the firm said. The people who died were inside the vehicle as it fell from the building. Nio says it immediately started an investigation...

Chicago exchange announces large network for sharing of quantum information

Flashes of what may become a transformative new technology are coursing through a network of optic fibers under Chicago. Researchers have created one of the world's largest networks for sharing quantum information – a field of science that depends on paradoxes so strange that Albert Einstein didn't believe them. The network, which connects the University of Chicago with Argonne National Laboratory in Lemont, is a rudimentary version of what scientists hope someday to become the internet of...

Meta board sees 1.1 million appeals over removed content

Meta's independent system of appeals against its decisions to remove content on Facebook and Instagram had about 1.1 million cases in its first year. The disputed posts, most of which originated in the U.S., Canada, and Europe, had largely been removed for violence, hate speech, or bullying, the BBC reports. Of the 20 cases about which the Oversight Board published decisions, it ruled against Meta 14 times. One case was about removed images of female breasts in...

Increased army mechanization reduces risk of coup d’état, study indicates

(Universitat Pompeu Fabra - Barcelona) A state's risk of a coup is negatively associated with its army's degree of mechanization, understood as the extent to which militaries depend on tanks and armored vehicles in relation to personnel. This is the main conclusion of a study involving Abel Escribà-Folch, a senior lecturer with the UPF Department of Political and Social Sciences, together with Ioannis Choulis from the University of Essex (United Kingdom), Marius Mehrl, from the University...

Musk’s Twitter deal gets unanimous board endorsement

Twitter's board has recommended unanimously that shareholders approve the proposed $44-billion sale of the company to Tesla CEO Elon Musk, according to a regulatory filing Tuesday. Musk reiterated his desire to move forward with the acquisition last week during a virtual meeting with Twitter employees, though shares of Twitter remain far below his offering price, signaling doubt that it will happen. On Tuesday at the Qatar Economic Forum in an interview with Bloomberg, Musk listed the approval of the...

Astronomers link 64 telescopes to observe structure of universe

(University of Manchester) An international team of astronomers has combined the power of 64 radio telescope dishes to detect the faint signatures of neutral hydrogen gas across cosmological scales. The feat was achieved using the South African-based MeerKAT telescope, a precursor to the world's largest radio observatory, the SKA Observatory (SKAO), which will probe the universe in unprecedented detail. A primary aim for the SKAO is to understand the evolution and content of the universe along...

Snake-venom gel found to help stop human bleeding scales toward commercial application

(University of Queensland) Some of the world's deadliest snakes could soon be saving lives, with research from The University of Queensland showing venom could be used to stop uncontrolled bleeding. The biomaterials research team from UQ's Australian Institute for Bioengineering and Nanotechnology (AIBN), led by postdoctoral research fellow Amanda Kijas, has found protein in the venom of two snakes – Australia's eastern brown snake eastern brown and scaled viper – could be used as an...
