Plantwatch: the plants that kill their insect pollinators
Jack-in-the-pulpit plants lure in gnats, cover them in pollen and trap them. As they struggle to escape they pollenate female flowersThere are two plant species with the most brutal flowers in the world, which deliberately kill their insect pollinators. The flowers of jack-in the pulpit,Arisaema angustatum, and its close relativeArisaema peninsulae are hidden inside a bowl-shaped wrapper with a narrow entrance, with a tall hood standing above. The floral dungeon lures in male fungus gnats, possibly by imitating the sexy scent of female gnats to fool the males into finding a mate.When the plants are small they only develop ...

Women almost twice as likely to be trapped in crashed vehicle, study finds
Exclusive: Calls to improve car design and safety as females also found to have different injury patterns to menWomen are almost twice as likely as men to become trapped in a motor vehicle after a crash and they also sustain different patterns of injury, data suggests.The research – the first large UK study to compare sex differences in injury patterns and the likelihood of becoming trapped after a collision – could help vehicle manufacturers improve car design and safety features to reduce rates of injury in both sexes. It also strengthens calls for the inclusion of more biologically accurate crash test dummies in sim...

Who owns Einstein? The battle for the world ’s most famous face
Thanks to a savvy California lawyer, Albert Einstein has earned far more posthumously than he ever did in his lifetime. But is that what the great scientist would have wanted?In July 2003, the physicist and Pulitzer-prize-nominated author Dr Tony Rothman received an email from his editor bearing unwelcome news. Rothman ’s new book was weeks from publication. An affable debunking of widely misunderstood stories from the history of science, the title, Everything’s Relative, was a playful nod to Albert Einstein’s theory of relativity. Rothman had asked his publisher, Wiley, to put a picture of history’s most famous sc...

New US lab to create versions of atoms never recorded on Earth
By studying isotopes scientists hope to gain insight into how elements within exploding stars came to beFrom carbon to uranium, oxygen to iron, chemical elements are the building blocks of the world around us and the wider universe. Now, physicists are hoping to gain an unprecedented glimpse into their origins, with the opening of a new facility that will create thousands of peculiar and unstable versions of atoms never before recorded on Earth.By studying these versions, known as isotopes, they hope to gain new insights into the reactions that created theelements within exploding stars, as well as testing theories about t...

We need a definitive exit from our Covid-19 pandemic. Here ’s the roadmap | Eric Topol
Nasal or oral vaccines, more and better drugs, and a variant-proof coronavirus vaccine could catalyze a clear way outAs the virus accelerates its evolution, the humans capitulate. For two and a half years, Covid-19 has been outrunning our response, getting more and more transmissible, reaching a level of infectiousness that few pathogens have ever attained. Instead of taking a stance of getting ahead of the virus, and outsmarting it, people have succumbed.In recent months, we experienced a striking jump in transmissibility when the Omicron (BA.1) variant became dominant, with at least a threefold increase in reproductive n...
