Prehistoric humans may have stuck pikes in ground to kill mammoths, say experts

People of ancient Clovis culture could have impaled huge animals on pikes rather than throwing spears, finds study

When it came to taking down giant animals, prehistoric hunters would quite literally have faced a mammoth task. Now researchers have shed fresh light on how they might have done it.

Experts studying sharp stone points made by the Clovis people, who lived in the Americas from about 13,000 years ago, say that rather than hurling spears at enormous animals such as giant bison, mammoths or ground sloths, the tribes could have planted their weapons point-up in the ground to impale charging creatures.

Head of Africa CDC Jean Kaseya urges international community to support rollout of testing and vaccinations

African health officials have appealed to the international community not to impose travel bans on countries dealing with an outbreak of mpox, but instead to support the continent in rolling out testing and vaccinations.

There have been about 1,400 new cases and 24 deaths linked to a new variant of mpox over the past week, according to the Africa Centres for Disease Control and Prevention.

US to survey dairy cattle brought to slaughter to study bird flu infections

Regulators will inspect cows to see how widespread virus is and determine whether ageing and cooking inactivate it

The US will track bird flu infections in dairy cows brought to slaughter to understand the ways the virus infects meat and will also continue testing raw milk cheeses to see whether the virus is inactivated in the ageing process.

The renewed focus on the US food chain is the latest front in the effort to combat the infectious bird flu virus, or H5N1, which has triggered alarm bells across the world as a potential future pandemic.

Why do whales beach themselves? A vial of parasites in a Tasmanian museum may hold the answer

Posted on by

Pilot whale that beached itself in 1973 was infested with thousands of parasitic nematodes that may have eaten away at its blowhole

A vial of white parasitic worms left for decades in a Tasmanian museum may help solve a timeless mystery: why do whales strand themselves on beaches?

The worms were collected from the blowhole of a pilot whale that beached itself in 1973 and then stored in Launceston’s Queen Victoria Museum and Art Gallery.

Mpox outbreak in Africa is public health emergency, declares WHO

Outbreak resembles early days of HIV, say experts, urging accelerated access to vaccines and testing

An outbreak in Africa of mpox, the disease formerly known as monkeypox, resembles the early days of HIV, scientists have said, as the World Health Organization declared it a public health emergency.

The declaration must accelerate access to testing, vaccines and therapeutic drugs in the affected areas, medical experts urged, and kickstart campaigns to reduce stigma surrounding the virus.

USC study finds cannabis can help manage withdrawal symptoms, as well as cravings and anxiety after withdrawal

New research from the University of Southern California shows that cannabis might help some people stop or cut down on their opioid use.

“We interviewed 30 people who were using opioids and cannabis and injecting drugs,” said Sid Ganesh, a PhD student at USC’s medical school and lead author of the study.

UK shortage of drug used to prevent brain damage in alcoholics

Experts say addiction patients are being treated as second-class citizens as ‘essential’ Pabrinex is withdrawn

Doctors have warned that a severe shortage of an “essential” medicine used to help protect alcoholics from degenerative brain conditions could disproportionately affect “some of the most vulnerable” in society.

Pabrinex, a multivitamin injection, is used to protect heavy drinkers from conditions such as Wernicke’s encephalopathy and Korsakoff syndrome, which can have symptoms similar to dementia. Doctors are concerned the incidence of these debilitating conditions may increase as a result of the shortages.

Australian kestrels may hold the key to helping drones hover

Posted on by

The wind hovering behaviour of the bird of prey is the ‘closest representation in the avian world to fixed wing aircraft’, says researcher

When researchers were hunting for a way to make drones fly more smoothly as they delivered food and packages, they turned to an unusual source for inspiration: the common kestrel.

RMIT and the University of Bristol researchers began tracking the flight motions of two Australian kestrels. They attached reflective markers to the birds and analysed their motion using a motion tracking system – the same technology used to create CGI effects.

‘Hobbit’ bones from tiny species of ancient humans found on Indonesian island

Flores arm bone suggests Homo floresiensis was forced to undergo a dramatic reduction in body size

The remains of a member of the smallest ancient human species on record, who stood at just 1m tall, have been discovered on the Indonesian island of Flores.

The fossil arm bone belonged to a tiny adult human who roamed the island 700,000 years ago alongside pygmy elephants, Komodo dragons and giant rats the size of rabbits. It is thought to be from a very early individual of the “hobbit” species Homo floresiensis that has perplexed scientists since its discovery two decades ago.

Analysis suggests extent of problem UN estimates is causing 500,000 deaths a year in sub-Saharan region

A fifth of medicines in Africa could be substandard or fake, according to a major research project, raising the alarm over a problem that could be contributing to the deaths of countless patients.

Researchers from Bahir Dar University in Ethiopia analysed 27 studies in the review and found, of the 7,508 medicine samples included, 1,639 failed at least one quality test and were confirmed to be substandard or falsified.

Egyptian mummy with screaming expression ‘may have died in agony’, say researchers

Archaeologists say wide open mouth of woman who died about 3,500 years ago may be caused by rare, immediate form of rigor mortis

She looks uncannily like The Scream painting by Edvard Munch, but just why an ancient Egyptian mummy has such a startling expression has long puzzled researchers. Now they say they may have the answer – suggesting the woman died crying out in agony.

The woman is thought to have been buried about 3,500 years ago and was discovered in 1935 in a wooden coffin beneath the tomb of Senmut – an important architect during the reign of the female pharaoh Hatshepsut.

Artefacts sent by farmer, who made the ‘absolutely mad’ discovery while cutting silage

When the national museum of Ireland received two 4,000-year-old axe heads, “thoughtfully” wrapped in foam inside a porridge box, from an anonymous source last month, it put out an appeal. The objects were “significant” and “exciting”, it said, but experts needed to know more about where exactly they had been found.

Now they have their answer: a farmer from County Westmeath has come forward as the mysterious sender, saying he made the “absolutely mad” discovery while using a metal detector on his land.

Krusatodon kirtlingtonensis, which lived 166m years ago, ‘a piece of the puzzle’ explaining mammals’ success

The remains of a diminutive mouse-like creature that lived 166m years ago could help answer one of biology’s biggest questions of why mammals have become so successful, fossil experts say.

Krusatodon kirtlingtonensis belongs to the immediate predecessors of mammals and lived alongside the dinosaurs during the middle Jurassic age. But while it was originally known only from individual teeth, researchers have now reported two partial skeletons.

Australian scientists genetically engineer common fly species to eat more of humanity’s waste

Black soldier flies could help cut planet-warming methane produced when organic waste breaks down, Macquarie University team says

A team of Australian scientists is genetically engineering a common fly species so that it can eat more of humanity’s organic waste while producing ingredients for making everything from lubricants and biofuels to high-grade animal feeds.

Black soldier flies are already being used commercially to consume organic waste, including food waste, but tweaking their genetics could widen the range of waste their larvae consume while, in the process, producing fatty compounds and enzymes.

Research argues tremors occurred as Vesuvius erupted in AD79, causing buildings to collapse on to people

Victims who perished in Pompeii after the devastating AD79 eruption of Mount Vesuvius may have been killed by a simultaneous earthquake, research has suggested.

Scholars have debated for decades whether seismic activity occurred during the eruption of Vesuvius in southern Italy nearly 2,000 years ago, and not just before it, as reported by Pliny the Younger in his letters.
