These ‘must-do’ itineraries people feel the need to undertake before they die can come with a heavy costIt was revealed last week that a retired lecturer named Darrell Meekcom had been arrested for indecent exposure and dangerous driving after he mooned a speed camera. It sounds as though he’d managed to perform a contortionist manoeuvre at the wheel but in fact he stopped the car and got...

Science YouTuber Philipp Dettmer: ‘Getting cancer was super-interesting’

The online star with 15 million subscribers on demystifying everything from black holes to the immune system, the trouble with anti-vaxxers, and what his cancer taught himSkim Philipp Dettmer’s CV and you’d have to say he was an improbable candidate to become one of the world’s foremost science communicators. The 35-year-old from Munich dropped out of high school in Germany aged 15. He...

Yes, DeepMind crunches the numbers – but is it really a magic bullet? | John Naughton

The machine learning outfit’s foray into pharmaceuticals could be very useful, but its grand claims should be taken with a pinch of saltThe most interesting development of the week had nothing to do with Facebook or even Google losing its appeal against a €2.4bn fine from the European commission for abusing its monopoly of search to the detriment of competitors to its shopping service.

Amazon Rainforest birds’ bodies transform due to climate change

The most pristine parts of the Amazon rainforest devoid of direct human contact are being impacted by human-induced climate change, according to new research. New analyses of data collected over the past four decades show that not only has the number of sensitive resident birds throughout the Amazon rainforest declined, but the body size and wing length have changed for most studied species. These...

For stem cells, bigger doesn’t mean better

A new study suggests that enlargement of stem cells contributes to age-related decline in function. The researchers found that blood stem cells, which are among the smallest cells in the body, lose their ability to perform their normal function -- replenishing the body's blood cells -- as they grow larger. When the cells were restored to their usual size, they behaved normally again.

DNA analysis confirms 2,000-year-old sustainable fishing practices of Tsleil-Waututh Nation

Ancient Indigenous fishing practices can be used to inform sustainable management and conservation today, according to a new study. Working with the Tsleil-Waututh Nation and using new palaeogenetic analytical techniques, the results of a new study provides strong evidence that prior to European colonization, Coast Salish people were managing chum salmon by selectively harvesting males.

Illuminating dark matter in human DNA

Researchers have produced a single-cell chromatin atlas for the human genome. Delineating chromatin regions in cells of different human tissue types would be a major step toward understanding the role of gene regulatory elements (non-coding DNA) in human health or disease.

Vascular defects appear to underlie the progression of Parkinson's disease

In an unexpected discovery, researchers have identified what appears to be a significant vascular defect in patients with moderately severe Parkinson's disease. The finding could help explain an earlier outcome of the same study, in which the drug nilotinib was able to halt motor and non-motor (cognition and quality of life) decline in the long term.

Best way to avoid procrastination

They say procrastination is the thief of time -- actually deadlines are. New research has found that if you want someone to help you out with something, it is best not to set a deadline at all. But if you do set a deadline, make it short.
