‘Disruptive’ science has declined — and no one knows why

‘Disruptive’ science has declined — and no one knows why

Nature reports: The number of science and technology research papers published has skyrocketed over the past few decades — but the ‘disruptiveness’ of those papers has dropped, according to an analysis of how radically papers depart from the previous literature. Data from millions of manuscripts show that, compared with the mid-twentieth century, research done in the 2000s was much more likely to incrementally push science forward than to veer off in a new direction and render previous work obsolete. Analysis…

Imagine if the current speaker impasse were occurring in a presidential inaugural year

Imagine if the current speaker impasse were occurring in a presidential inaugural year

The Bulwark reports: As Kevin McCarthy repeatedly fails to secure enough votes to become speaker and the House of Representatives sits in limbo, Democrats say they are increasingly concerned about the risks to national security involved in a prolonged period without any active members or ability to conduct legislative business. Currently, every elected member of the House has yet to be sworn in to office, leaving committee structures up in the air and creating a backlog of onboarding for freshmen…

In House speaker fight, Trump struggles to play kingmaker

In House speaker fight, Trump struggles to play kingmaker

The New York Times reports: After Kevin McCarthy failed to win enough votes to become House speaker on Tuesday, former President Donald J. Trump held a call with Mr. McCarthy and Scott Perry of Pennsylvania, one of the key Republican members of Congress blocking Mr. McCarthy’s bid. Mr. Trump’s goal was to break the logjam. But if Mr. Trump had wanted Mr. Perry to quickly flip, it wasn’t to be: The next day, Mr. Perry voted against Mr. McCarthy three…

Kevin McCarthy is showing other Republicans how much there is to gain from pushing him around

Kevin McCarthy is showing other Republicans how much there is to gain from pushing him around

Michelle Goldberg writes: McCarthy evidently believed that by courting Georgia’s Marjorie Taylor Greene, an avatar of hyper-performative politics, he could co-opt her wing of the party. He was set to offer her valuable committee assignments, and, according to Draper, had even offered to create a new leadership position for her. But her elevation would be valuable to other Trumpists only if there were concrete things they hoped to accomplish together. Putting Greene on the Oversight Committee does nothing to help…

U.S. and Germany agree to send infantry fighting vehicles to Ukraine

The Guardian reports: Joe Biden and his German counterpart Olaf Scholz have agreed to send infantry fighting vehicles to help Ukraine fight Russia, a day after France said it would supply its own armoured vehicles to Kyiv in an attempt to create a breakthrough in the 10-month war. The joint announcement followed a phone call between Biden and Scholz and amounts to a step change in western military support for Ukraine, which has asked for up to 700 armoured vehicles…

Number of populist world leaders at 20-year low

The Guardian reports: The number of populist leaders around the world has fallen to a 20-year low after a series of victories for progressives and centrists over the past year, according to analysis from the Tony Blair Institute showing the number of people living under populist rule has fallen by 800 million in two years. The research claims 2023 could be an equally decisive year for populism, with critical elections in Turkey and Poland. Those two elections could see two…

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…

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

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.

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…
