That is probably why they are the second most popular pizza topping, next to pepperoni.In the past, food scientists like me often praised mushrooms as healthy because of what they don’t contribute to the diet; they contain no cholesterol and gluten and are low in fat,...

The UK's app failure sums up our fatally flawed coronavirus response | John Naughton

Thanks to dithering and ineptitude, we may never have contact tracing on our smartphonesCoronavirus – latest updatesSee all our coronavirus coverageI’ve just been looking at the coronavirus death toll in various countries as tallied on the Johns Hopkins University Covid-19 tracker. At the time I checked, the UK had 45,407 deaths, Poland had 1,642, Ireland had 1,753, New Zealand had 1,555 and...

I Lived in a Dome in Hawaii to Simulate Life on Mars

It was the crew’s first night, we had just arrived, we were settling in. Kim Binsted, principle investigator on the HI-SEAS project, was preparing to leave for four months, nervous, I think, about launching this Mars mission, a project whose actualization was so uncertain throughout the buildup—NASA nearly pulled funding, there were delays in the construction of the habitat—that at times it...

A change to the zodiac? This should never have been written into the stars

There has been a lot of talk about the Ophiuchus constellation joining the zodiac, but I won’t be changing my Cancerian waysI am zodiac person. I have five books on the zodiac (and am open to many more). When I meet someone, before they have even opened their mouth I’ll be trying to figure out what their star sign is. I’m not so into this stuff that I’ll dislike or avoid certain signs, but...

Ground system for NASA's Roman Space Telescope completes major review

When it launches in the mid-2020s, NASA's Nancy Grace Roman Space Telescope will create enormous panoramic pictures of space in unprecedented detail. The mission's wide field of view will enable scientists to conduct sweeping cosmic surveys, yielding a wealth of new information about the universe.

‘A meteor will go by, and everyone gasps’: meet the world’s most dedicated stargazers

Every year, amateur telescope makers gather under starry skies in the US and South Africa – to trade tips and tales from across the universeYou have to be rigorous. You need perseverance. You must be meticulously clean. But even if you possess all these skills, none of them matters if you are in a hurry. Because there is one thing enthusiasts make clear from the start: building a telescope from...

Wetter than wet: Global warming means more rain for Asian monsoon regions

Researchers from Tokyo Metropolitan University studied how the weather will change with global warming in Asian monsoon regions using a high-resolution climate simulation. The region is home to a large population, and the monsoons are a major driver of global water cycles. They explicitly simulated cloud formation and dissipation, and found significantly increased precipitation over the monsoon...

Fossil tracks: Wrong number of fingers leads down wrong track

Have you ever wondered why our hands have five fingers while amphibians usually only have four? Until now it was assumed that this was already the case with the early ancestors of today's frogs and salamanders, the Temnospondyli. However, a new find of the crocodile-like Temnospondyl Metoposaurus krasiejowensis (about 225 million years old) in Poland shows five metacarpal bones and thus five...

U.S. Eyes Building Nuclear Power Plants on the Moon, Mars

(BOISE, Idaho) — The U.S. wants to build nuclear power plants that will work on the moon and Mars, and on Friday put out a request for ideas from the private sector on how to do that. The U.S. Department of Energy put out the formal request to build what it calls a fission surface power system that could allow humans to live for long periods in harsh space environments. The Idaho National...
