How worried should we be about XBB.1.5?

How worried should we be about XBB.1.5?

Katherine J. Wu writes: After months and months of SARS-CoV-2 subvariant soup, one ingredient has emerged in the United States with a flavor pungent enough to overwhelm the rest: XBB.1.5, an Omicron offshoot that now accounts for an estimated 75 percent of cases in the Northeast. A crafty dodger of antibodies that is able to grip extra tightly onto the surface of our cells, XBB.1.5 is now officially the country’s fastest-spreading coronavirus subvariant. In the last week of December alone,…

Humans are still evolving thanks to microgenes

Humans are still evolving thanks to microgenes

The Scientist reports: Humans are still evolving new genes, according to a study published in Cell Reports on December 20. As our lineage evolved, at least 155 human genes sprung up from DNA regions previously thought of as “junk,” including two human-specific genes that emerged since humans branched off from chimpanzees around 4 to 6 million years ago, the researchers report. “I thought it was a great study,” says Alan Saghatelian, a biologist at the Salk Institute who was not…

The Kevin McCarthy mess is peak Trumpism

The Kevin McCarthy mess is peak Trumpism

Molly Jong-Fast writes: Despite his best efforts, the leopards have finally come for Kevin McCarthy’s face. For those not extremely online, I’m referring to a 2015 tweet from YA novelist Adrian Bott: “‘I never thought leopards would eat MY face,’ sobs woman who voted for the Leopards Eating People’s Faces Party.” It’s nearly eight years later and McCarthy is learning this lesson the hard way, as his quixotic quest for the Speakership, which spanned most of that time, is falling…

France to deliver ‘light tanks’ to Ukraine

Politico reports: France will deliver “light” battle tanks to Ukraine, President Emmanuel Macron’s office announced Wednesday, which would make it the first country to send such Western-designed armored fighting vehicles to the wartorn country. The Elysée said after a phone call between Macron and his Ukrainian counterpart Volodymyr Zelenskyy that France will send AMX-10 RC armored fighting vehicles, which Paris has been gradually replacing with new Jaguar battle tanks. Several countries have already sent Soviet-era tanks to Ukraine. Both France…

Ukraine says Russia plans new mobilisation to ‘turn tide of war’

Ukraine says Russia plans new mobilisation to ‘turn tide of war’

Reuters reports: Ukraine’s President Volodymyr Zelenskiy said Russia was planning to call up more troops for a major new offensive, even as Moscow was facing some of its biggest internal criticism of the war over a strike that killed scores of fresh conscripts. Kyiv has been saying for weeks that Russian President Vladimir Putin plans to order another mass conscription drive and shut his borders to prevent men from escaping the draft. “We have no doubt that the current masters…

A single Iranian attack drone found to contain parts from more than a dozen U.S. companies

A single Iranian attack drone found to contain parts from more than a dozen U.S. companies

CNN reports: Parts made by more than a dozen US and Western companies were found inside a single Iranian drone downed in Ukraine last fall, according to a Ukrainian intelligence assessment obtained exclusively by CNN. The assessment, which was shared with US government officials late last year, illustrates the extent of the problem facing the Biden administration, which has vowed to shut down Iran’s production of drones that Russia is launching by the hundreds into Ukraine. CNN reported last month…

John Kerry: Rich countries must respond to developing world anger over climate

John Kerry: Rich countries must respond to developing world anger over climate

The Guardian reports: People in developing countries are feeling increasingly angry and “victimised” by the climate crisis, the US climate envoy John Kerry has warned, and rich countries must respond urgently. “I’ve been chronicling the increased frustration and anger of island states and vulnerable countries and small African nations and others around the world that feel victimised by the fact that they are a minuscule component of emissions,” he said. “And yet [they are] paying a very high price. Seventeen…

Inside ancient asteroids, gamma rays made building blocks of life

Inside ancient asteroids, gamma rays made building blocks of life

John Rennie and Allison Parshall write: In 2021, the Hayabusa2 space mission successfully delivered a morsel of the asteroid 162173 Ryugu to Earth — five grams of the oldest, most pristine matter left over from the solar system’s formation 4.5 billion years ago. Last spring, scientists revealed that the chemical composition of the asteroid includes 10 amino acids, the building blocks of proteins. The discovery added to the evidence that the primordial soup from which life on Earth arose may…

The remarkable emptiness of existence

The remarkable emptiness of existence

Paul M Sutter writes: In 1654 a German scientist and politician named Otto von Guericke was supposed to be busy being the mayor of Magdeburg. But instead he was putting on a demonstration for lords of the Holy Roman Empire. With his newfangled invention, a vacuum pump, he sucked the air out of a copper sphere constructed of two hemispheres. He then had two teams of horses, 15 in each, attempt to pull the hemispheres apart. To the astonishment of…

Pro-Putin operatives in Germany work to turn Berlin against Ukraine

Pro-Putin operatives in Germany work to turn Berlin against Ukraine

Reuters reports: In a square beneath the twin spires of Cologne’s gothic cathedral, around 2,000 protesters gathered in September to urge Germany’s government to break with the Western coalition backing Ukraine and make peace with Russia. “We must stop being vassals of the Americans,” right-wing German politician Markus Beisicht said from a makeshift stage on the back of a truck. The crowd clapped and waved Russian and German flags. A lean man in camouflage trousers stood at the side of…

Defending against Russian drones is expensive, but Ukraine sees the cost as worth it

Defending against Russian drones is expensive, but Ukraine sees the cost as worth it

The New York Times reports: They are lumbering and noisy and relatively easy to shoot from the sky. Over the New Year’s weekend, the Ukrainian military said it downed every single one of the 80-odd exploding drones that Russia sent the country’s way. “Such results have never been achieved before,” a Ukrainian Air Force spokesman said on Tuesday. But beneath that result lies a question: How long can Ukraine sustain its effort when many of its defensive measures cost far…

The right has already won the House speakership election

The right has already won the House speakership election

Ronald Brownstein writes: No matter how they resolve Tuesday’s vote choosing the next speaker of the House, Republicans appear poised to double down on the hard-edged politics that most swing state voters rejected in last November’s midterm election. Stubborn conservative resistance to House GOP Leader Kevin McCarthy has put the party at risk of precipitating the first speakership election that extends to more than a single ballot since 1923 – and only the second since the Civil War. But even…

China is flying blind as pandemic rages

China is flying blind as pandemic rages

Science reports: Most scientists believe China’s decision to end its zero-COVID policy was long overdue. But now they have a new worry: that the country is collecting and sharing far too little data about the rough transition to a new coexistence with the virus. China abruptly dropped virtually all controls a month ago, after protests, a sagging economy, and the extreme transmissibility of the virus’ latest variants made clinging to zero COVID untenable. Now, “SARS-CoV-2 has an open goal in…

80% of new cars sold in Norway are now electric vehicles

CBS News reports: Electric vehicles accounted for almost four out of every five new car registrations in Norway last year, setting a new record, according to figures released Monday. Led by U.S. carmaker Tesla, which topped the list with a 12.2% market share, 138,265 new electric cars were sold in the Scandinavian country last year, representing 79.3% of total passenger car sales, the Norwegian Road Federation (OFV) said in a statement. In doing so, Norway, which is both a major…
