For well over a century, we had the opportunity to study Neanderthals—their bones, the items they left behind, their distribution across Eurasia. So, when we finally obtained the sequence of their genome and discovered that we share a genetic legacy with them, it was easy to place the discoveries into context. In contrast, we had no idea Denisovans existed when sequencing DNA from a small finger bone revealed that yet another relative of modern humans had roamed Asia in the recent past.

Since then, we've learned little more. The frequency of their DNA in modern human populations suggest that they were likely concentrated in East Asia. But we've only discovered fragments of bone and a few teeth since then, so we can't even make very informed guesses as to what they might have looked like. On Wednesday, an international group of researchers described finds from a cave on the Tibetan Plateau that had been occupied by Denisovans, which tell us a bit more about these relatives: what they ate. And that appears to be anything they could get their hands on.

A team of researchers led by an archaeologist at the University of Sydney are the first to suggest that eyed needles were a new technological innovation used to adorn clothing for social and cultural purposes, marking the major shift from clothes as protection to clothes as an expression of identity.

"Eyed needle tools are an important development in prehistory because they document a transition in the function of clothing from utilitarian to social purposes," says Dr. Ian Gilligan, Honorary Associate in the discipline of Archaeology at the University of Sydney.

From stone tools that prepared animal skins for humans to use as thermal insulation, to the advent of bone awls and eyed needles to create fitted and adorned garments, why did we start to dress to express ourselves and to impress others?

A team of geneticists and archaeologists affiliated with multiple institutions in France has uncovered skeletons in an ancient gravesite not far from Paris that show evidence of steppe migrant integration with Late Neolithic Europeans. The study is published in the journal Science Advances.

Prior research has shown that there was a slow migration of herding people from what is now Russia and Ukraine to Europe thousands of years ago. During the migrations, many of the migrants (who were mostly male) produced children with the local farmers they encountered.

In this new study, the research team reports evidence of such reproduction in remains found in an open grave in the Champagne region of France. Skeletons in the grave showed evidence of a native European woman who had produced a child with a steppe migrant.

In the early 1600s, the officials running Durham Cathedral, in England, had serious financial problems. Soaring prices had raised expenses. Most cathedral income came from renting land to tenant farmers, who had long leases so officials could not easily raise the rent. Instead, church leaders started charging periodic fees, but these often made tenants furious. And the 1600s, a time of religious schism, was not the moment to alienate church members.

But in 1626, Durham officials found a formula for fees that tenants would accept. If tenant farmers paid a fee equal to one year's net value of the land, it earned them a seven-year lease. A fee equal to 7.75 years of net value earned a 21-year lease.

This was a form of discounting, the now-common technique for evaluating the present and future value of money by assuming a certain rate of return on that money. The Durham officials likely got their numbers from new books of discounting tables. Volumes like this had never existed before, but suddenly local church officials were applying the technique up and down England.

Supporters of former President Donald Trump, including a former Wisconsin Supreme Court justice, submitted more than 9,000 signatures on Tuesday in an effort to force a recall election of Wisconsin’s top elected Republican after their first attempt fell short.

They targeted Assembly Speaker Robin Vos, the longest-serving Assembly speaker in Wisconsin history, after he refused to impeach the official who oversees the battleground state’s elections, angering Trump and his followers.

The bipartisan Wisconsin Elections Commission must determine whether there are enough valid signatures to trigger a recall election. The panel rejected the first attempt for not having enough valid signatures.

Petition circulators said they submitted 9,022 signatures primarily from voters in the district where Vos was elected to serve most recently in 2022, not the one where he lives now under new lines in place for the November election. They need 6,850 valid signatures to force a recall election in the district where Vos was elected to serve.

In March, the group submitted more than 9,000 signatures but of those the elections commission determined that only 5,905 were valid.

Moose populations have been dwindling for years across the country due to many contributing factors, but new research at Washington State University has found the impact of Eleaophora schneideri, also known as the arterial worm, has likely been underestimated.

Researchers examined recently deceased Shiras moose in Idaho between March 2020 and July 2022. While the parasitic roundworm E. schneideri was not detected in any of the animals found in north Idaho, it was present in 10 of the 20 adult moose studied in the southeastern portion of the state. Nine of the infected not only had adult worms in their major arteries but their brains were littered with microfilariae, the microscopic early life stage of the worm.

"The microfilaria are just scattered throughout their brains, and even though the damage from each is miniscule, they're basically shot-gunning the whole brain," said Kyle Taylor, a pathologist at WSU's Washington Animal Disease Diagnostics Laboratory. "We hypothesize the cumulative effects of large numbers of microfilariae in the brain may be associated with increased morbidity or chance of mortality, with mortality more likely in cases with larger numbers of worms."

The U.S. has a long record of extracting resources on Native lands and ignoring tribal opposition, but a decision by federal energy regulators to deny permits for seven proposed hydropower projects suggests that tide may be turning.

As the U.S. shifts from fossil fuels to clean energy, developers are looking for sites to generate electricity from renewable sources. But in an unexpected move, the Federal Energy Regulatory Commission denied permits on Feb. 15, 2024, for seven proposed hydropower projects in Arizona and New Mexico.

The reason: These projects were located within the Navajo Nation and were proposed without first consulting with the tribe. FERC said it was “establishing a new policy that the Commission will not issue preliminary permits for projects proposing to use Tribal lands if the Tribe on whose lands the project is to be located opposes the permit.”

The Biden administration’s aggressive set of antitrust enforcers have created powerful enemies: in big business, in media, in academia, and in Washington. For the most part, the main antagonists of the Federal Trade Commission and the Department of Justice’s Antitrust Division have been Republicans, though there are a few Khanservatives. But now, pro-corporate Democrats are getting in on the act, targeting an obscure but critical policy designed to give enforcers the information they need to judge proposed corporate mergers.

Carnauba wax is a product you may not have heard of, but you have almost certainly consumed it - it is added to sweets to stop them melting, to pills to make them easier to swallow and as a thickener in lipstick and mascara.

Workers in Brazil's poor north-eastern state of Piauí rely on harvesting wax from carnauba palm trees to earn a living. But the power is in the hands of big business who, authorities say, are turning a blind eye to exploitation.

Ötzi the Iceman's many tattoos were made by "hand-poking" — a manual version of the tattooing technique usually used today — and not by cutting his skin as some researchers have suggested, according to a new study.

Ötzi died in Europe's Alps about 5,300 years ago, and his body remained mummified there for thousands of years until tourists discovered it in 1991 on a mountain pass near the border of Italy and Austria. Studies have since revealed many aspects of his life, including the tools and weapons he carried, his clothes and his last meal.

There have also been studies of Ötzi's 61 tattoos; but while it's often reported they were made by cutting the skin and rubbing soot into the incision, that doesn't seem to have been the case, according to study first author Aaron Deter-Wolf, an expert on ancient tattooing who works for the state of Tennessee's Department of Environment and Conservation.

Instead, "within reasonable doubt they are hand-poked, rather than being incised or being done in any other style," Deter-Wolf told Live Science.

John Barnett had worked for Boeing for 32 years, until his retirement in 2017.

In the days before his death, he had been giving evidence in a whistleblower lawsuit against the company.

Boeing said it was saddened to hear of Mr Barnett's passing. The Charleston County coroner confirmed his death to the BBC on Monday.

It said the 62-year-old had died from a "self-inflicted" wound on 9 March and police were investigating.

A group of protesters in Mexico City have driven a pickup truck through a door to the country's presidential palace.

They were met by police officers, who used tear gas on the protesters.

The group were protesting the 2014 mass disappearance a group of 43 Mexican students. A commission set up to investigate the case later described it as "a crime of the state".
