PFAS increase likelihood of death by cardiovascular disease, study shows

Posted on by

In a first, researchers were able to compare records of people who drank polluted water in Veneto, Italy, with neighbors who did not

For the first time, researchers have formally shown that exposure to toxic PFAS increases the likelihood of death by cardiovascular disease, adding a new level of concern to the controversial chemicals’ wide use.

The findings are especially significant because proving an association with death by chemical exposure is difficult, but researchers were able to establish it by reviewing death records from northern Italy’s Veneto region, where many residents for decades drank water highly contaminated with PFAS, also called “forever chemicals”.

Research finds hormone that indicates fertility at lower levels in vapers and tobacco smokers

Women should give up vaping if they are hoping to get pregnant, according to a study that suggests it may affect fertility.

In the first research to demonstrate a link between fertility prospects and electronic cigarettes across a large population, analysis of blood samples from 8,340 women revealed that people who vape or smoke tobacco had lower levels of anti-Müllerian hormone (AMH), which indicates how many eggs women have left in their ovaries.

Fossil of ‘largest snake to have ever existed’ found in western India

Scientists estimate Vasuki indicus was up to 15m long, weighed a tonne and would have constricted its prey

Fossil vertebrae unearthed in a mine in western India are the remains of one of the largest snakes that ever lived, a monster estimated at up to 15 metres in length – longer than a T rex.

Scientists have recovered 27 vertebrae from the snake, including a few still in the same position as they would have been when the reptile was alive. They said the snake, which they named Vasuki indicus, would have looked like a large python and would not have been venomous.

Tasmanian devil analysis challenges study suggesting facial tumour disease decline

Posted on by

Cambridge scientists critique research that concluded the disease is no longer a threat to the species’ survival

Cambridge researchers have challenged a previous study which had concluded a facial cancer that devastated the Tasmanian devil population was on the decline.

Devil facial tumour disease, a fatal cancer spread through biting and sharing of food, first emerged in the 1980s. The spread of DFTD led to the species being listed as endangered by the International Union for Conservation of Nature in 2008.

Australia records lowest seven-day Covid death rate for more than two years

Posted on by

Expert says immunity from vaccines and Omicron infections have combined to reduce severe disease

Australia has recorded its lowest Covid death rate for more than two years, according to federal health department data that dates back to January 2022.

The latest data on the National Notifiable Diseases Surveillance System shows that between Thursday 29 February and Saturday 2 March, and on 5 and 6 March, the seven-day rolling average for Covid deaths was zero. One death was recorded on 3 March. The average is used to indicate short-term trends and is calculated by dividing the number of deaths in the previous seven days by seven and rounding to the nearest whole number. Up to three deaths in seven days results in a rolling average of zero.

Clues at Argentina site raise possibility mammal was buried with human owners about 1,500 years ago

The remains of a fox unearthed at a human burial site in Argentina dating back 1,500 years has raised the possibility the animal may have been kept as a pet, research suggests.

Experts say the remains predate the arrival of domestic dogs in Patagonia, which occurred about 700–900 years ago, with a number of clues suggesting the fox was seen as valuable, and may even have been a companion to the hunter-gatherers it lived with.

Great Barrier Reef discovery overturns belief Aboriginal Australians did not make pottery, archaeologists say

Paper dates 82 pottery pieces found in single dig site at between 3,000 and 2,000 years old

Groundbreaking archaeological research may have upended the longstanding belief that Aboriginal Australians did not make pottery.

A paper published in the Quaternary Science Reviews on Wednesday details the finding of 82 pottery pieces from a single dig site on a Great Barrier Reef island, dates them at between 3,000 and 2,000 years old and determines that the pots were most likely made by Aboriginal people using locally sourced clay and temper.

Almost 32 million people in the path of totality as moon’s shadow crossed the Mexico-Texas border and then traversed 15 states

The ethereal spectacle of a total solar eclipse swept across North America on Monday afternoon, giving tens millions of people in Mexico, the US and Canada the chance to witness a rare and dazzling celestial show.

Almost 32 million people were in the path of totality as the moon’s shadow crossed the Mexico-Texas border at lunchtime and traversed 15 states over the next hour and a half, although many, especially in the south and midwest, were denied a clear view by low clouds and rain.

The French aristocrat who understood evolution 100 years before Darwin – and even worried about climate change

Georges-Louis Leclerc proposed species change and extinction back in the 1740s, a new book reveals

Shortly after Charles Darwin published his magnum opus, The Origin of Species, in 1859 he started reading a little-known 100-year-old work by a wealthy French aristocrat.

Its contents were quite a surprise. “Whole pages [of his book] are laughably like mine,” Darwin wrote to a friend. “It is surprising how candid it makes one to see one’s view in another man’s words.”

In later editions of The Origin of Species, Darwin acknowledged Georges-Louis Leclerc, Comte de Buffon, as one of the “few” people who had understood that species change and evolve, before Darwin himself.

What do animals do during an eclipse? Observers in US zoos hope to find out

Frantic giraffes, barking gibbons, randy tortoises … previous solar eclipses have revealed varied responses to sudden onset of darkness

Not every scientist’s attention will be focused on the skies during Monday’s solar eclipse. Animal behaviorists at several zoos across its pathway will be watching creatures great and small for their reactions to the sudden, unexpected darkness.

The research is an extension of their observations from 2017’s most recent total eclipse in the US, when usually sedentary tortoises started rutting, frantic giraffes ran around aimlessly, and siamang gibbons embarked on an abrupt and tumultuous chorus of screams and barks.

Scientists confirm record highs for three most important heat-trapping gases

Posted on by

Global concentrations of carbon dioxide, methane and nitrous oxide climbed to unseen levels in 2023, underlining climate crisis

The levels of the three most important heat-trapping gases in the atmosphere reached new record highs again last year, US scientists have confirmed, underlining the escalating challenge posed by the climate crisis.

The global concentration of carbon dioxide, the most important and prevalent of the greenhouse gases emitted by human activity, rose to an average of 419 parts per million in the atmosphere in 2023 while methane, a powerful if shorter-lasting greenhouse gas, rose to an average of 1922 parts per billion. Levels of nitrous oxide, the third most significant human-caused warming emission, climbed slightly to 336 parts per billion.

‘I get emotional thinking about it’: US and Canada ready for total solar eclipse

Cities expect huge crowds with millions gathering in 115-mile wide ‘path of totality’ for Monday’s exceptionally large and long eclipse

Should the weather gods grant their blessing, a celestial show for the ages will darken the heavens over a large swathe of the US from Texas to Maine on Monday, giving tens of millions of people a grandstand view of a rare phenomenon being billed as “the Great American Eclipse”.

It will be another 20 years until the next total solar eclipse can be viewed anywhere in the contiguous US, lending extra incentive for many who live outside the 115-mile wide “path of totality” to travel in and experience the moments of twilight, stillness and a sudden temperature drop the event will bring.
