Last weekend’s Cambridgeshire train attack brought up a question that we often ask ourselves. But the answer isn’t simple

The devastating attack on train passengers in Cambridgeshire last weekend was shocking. There has been talk of heroes who risked their lives to help others, and of those who hid to save their lives. If you are anything like me, you will be asking yourself: what if that were me? How would I cope? And just who would I turn out to be when the worst happens?
Some of us imagine that we would vault to the rescue, fighting off attackers. Others, perhaps the more realistic among us, anticipate flight, extricating ourselves from the situation as quickly and efficiently as possible. Most of us would like to think that we would stay our urge to run, lingering long enough to offer aid to those in need.

Modern research shows the public work together selflessly in an emergency, motivated by a strong impulse to help
It was early morning on 1 January last year when Colin McGarva dived into a flooding river in Worcester to rescue an unconscious woman. McGarva said he didn’t think twice about the risk to himself, or the devastating loss his newborn son would suffer had he too been swept away by the fast-flowing icy waters.
“I didn’t stop to think because the instinct – the instant reaction – is to help someone in need,” he said. “Someone’s life is an important thing. Helping is just something you have to do.”

Nobel prize winner shaped medicine, crimefighting and genealogy, but later years marred by racist remarks
James Dewey Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution in medicine, crimefighting, genealogy and ethics, has died, according to his former research lab. He was 97.
The breakthrough – made when the brash, Chicago-born Watson was just 24 – turned him into a hallowed figure in the world of science for decades. But near the end of his life, he faced condemnation and professional censure for offensive remarks, including saying Black people were less intelligent than white people.

Droughts and heatwaves causing water in some areas to reach 41C, killing fish and endangered dolphins, say researchers
Amazonian lakes are being transformed into simmering basins hotter than spa baths as severe heatwaves and drought grip the region, research shows.
The temperature of one lake exceeded 40C (104F) as water levels plummeted under intense sunlight and cloudless skies. The extreme heat triggered mass die-offs among endangered Amazon river dolphins and fish, which cannot survive in such high temperatures.

Une nouvelle recherche publiée dans Monthly Notices of the Royal Astronomical Society remet en cause l’idée selon laquelle l’Univers serait en expansion accélérée constante. Selon l’équipe de l’université de Yonsei dirigée par le professeur Young‑Wook Lee, « l’Univers est déjà entré dans une phase d’expansion ralentie à l’époque …

L’article L’univers pourrait déjà « ralentir » : une étude coréenne questionne la théorie de l’expansion accélérée est apparu en premier sur KultureGeek.
Le constat est terrible : une nouvelle étude récemment menée par l’Oxford Internet Institute révèle que les outils de référence utilisés pour évaluer les intelligences artificielles sont souvent trompeurs, voire carrément inadaptés à ce que l’on cherche à évaluer. Les chercheurs ont passé en revue plus de 445 …
