EU pumps four times more money into farming animals than growing plants

news.movim.eu / TheGuardian · Monday, 1 April - 15:00

CAP scheme, which pays more to farms that occupy more land, drives ‘perverse outcomes for a food transition’, says study

The EU has made polluting diets “artificially cheap” by pumping four times more money into farming animals than growing plants, research has found.

More than 80% of the public money given to farmers through the EU’s common agriculture policy (CAP) went to animal products in 2013 despite the damage they do to society, according to a study in Nature Food . Factoring in animal feed doubled the subsidies that were embodied in a kilogram of beef, the meat with the biggest environmental footprint, from €0.71 to €1.42 (61p to £1.22).

Smartphone app could help detect early-onset dementia cause, study finds

news.movim.eu / TheGuardian · Monday, 1 April - 15:00

App-based cognitive tests found to be proficient at detecting frontotemporal dementia in those most at risk

A smartphone app could help detect a leading cause of early-onset dementia in people who are at high risk of developing it, data suggests.

Scientists have demonstrated that cognitive tests done via a smartphone app are at least as sensitive at detecting early signs of frontotemporal dementia in people with a genetic predisposition to the condition as medical evaluations performed in clinics.

Daily Telescope: A flying telescope gets photobombed by some planets

Welcome to the Daily Telescope . There is a little too much darkness in this world and not enough light, a little too much pseudoscience and not enough science. We'll let other publications offer you a daily horoscope. At Ars Technica, we're going to take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.

Good morning. It's April 1, and today's photo showcases an airplane—but it's a special airplane with some celestial treats in the background.

The plane is a shortened version of a Boeing 747 that housed the Stratospheric Observatory for Infrared Astronomy, known as SOFIA. This airborne observatory first took flight in May 2010 and operated through September 2022. The 2.5-meter telescope flew at about 45,000 feet and observed all manner of phenomena from a vantage point above much of the Earth's atmosphere—celestial magnetic fields, star-forming regions, comets, and more.

Total solar eclipse to sweep across Mexico, the US and Canada

news.movim.eu / TheGuardian · Monday, 1 April - 05:00

The moon will pass directly in front of the sun, exposing ghostly traces of the sun’s atmosphere

A total solar eclipse will sweep across the Pacific Ocean, through Mexico, the US and Canada and end over the Atlantic Ocean on 8 April.

The phenomenon occurs when the moon passes directly in front of the sun, blocking out the bright surface and revealing the ghostly traces of the sun’s atmosphere.

Scientist who gene-edited babies is back in lab and ‘proud’ of past work despite jailing

news.movim.eu / TheGuardian · Monday, 1 April - 04:52

China’s He Jiankui, who used Crispr to edit genome, says he is working on genetic diseases and suggests human embryo gene editing will one day be accepted

A Chinese scientist who was imprisoned for his role in creating the world’s first genetically edited babies says he has returned to his laboratory to work on the treatment of Alzheimer’s and other genetic diseases.

In an interview with a Japanese newspaper, He Jiankui said he had resumed research on human embryo genome editing, despite the controversy over the ethics of artificially rewriting genes, which some critics predicted would lead to demand for “designer babies”.

‘I’m as baffled as the next ovary-owner’: navigating the science of treating menopause

news.movim.eu / TheGuardian · Sunday, 31 March - 23:00

Conversations about menopause have matured but the question of when and how to treat perimenopausal symptoms remains confusing – even to a science journalist

There’s a meme featuring a confident, suave, smiling Henry Cavill – the actor best known for playing Superman – posing for photographers on the red carpet. Sneaking up behind him is wild-looking, maniacally gleeful co-star Jason Momoa.

To me, this is the perfect metaphor for perimenopause. Cavill is at the peak of his career, he looks great, clearly feels great, exudes confidence, strength and self-possession. And he’s about to get crash-tackled by a capricious and unpredictable force.

Rocket Report: Multi-day delay for the final Delta launch; Orbex patents landing tech

Welcome to Edition 6.37 of the Rocket Report! The big story this week is the final launch of the Delta IV Heavy rocket, which is one of the biggest spectacles to enjoy lifting away from the planet. Because of a scrub on Thursday, there is still time to clear your calendar for a second attempt on Friday at 1:37 pm ET in Florida.

As always, we welcome reader submissions , and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Orbex patents reusable rocket tech . The British launch company said this week it has patented a "REFLIGHT" technology that enables the recovery of the first stage of its small Prime rocket. Essentially, Orbex designed an interstage that will function somewhat like grid fins on the Falcon 9 rocket's first stage. "After Stage 1 detaches from Stage 2, the interstage on top of Stage 1 reconfigures into four ‘petals’ which fold out and create drag forces that passively reorients and slows the spent rocket stage’s descent to Earth," the company stated.

After the Concorde, a long road back to supersonic air travel

When Chuck Yeager reached Mach 1 on October 14, 1947, the entire frame of his Bell X-1 aircraft suddenly started to shake, and the controls went. A crew observing the flight in a van on the ground reported hearing something like a distant, rolling thunder. They were probably the first people on Earth to hear a boom made by a supersonic aircraft.

The boom felt like an innocent curiosity at first but soon turned into a nightmare. In no time, supersonic jets—F-100 Super Sabers, F-101 Voodoos, and B-58 Hustlers—came to Air Force bases across the US, and with them came the booms. Proper, panes-flying-off-the windows supersonic booms. People filed over 40,000 complaints about nuisance and property damage caused by booming jets, which eventually ended up with the Federal Aviation Administration imposing a Mach 1 speed limit for flights over land in 1973.

Now, NASA wants this ban to go. It has started the Quesst mission to go fast over American cities once more. But this time, it wants to do it quietly.

Copernicus online portal offers terrifying view of climate emergency

news.movim.eu / TheGuardian · Friday, 29 March - 06:00

Looking at the mass of information, there is only one conclusion: we are running out of time

There is so much information on the newly launched Copernicus Climate Change Service atlas that my laptop started to overheat trying to process it all. As well as all the past data, it predicts where the climate is going and how soon we will breach the 1.5C “limit”, and then 2C. You can call up the region where you live, so it is specific to what is happening to you and your family – and all the more disturbing for that.

A separate part called Climate Pulse intended particularly for journalists is easier to operate. The refreshing bit is that the maps, charts and timelines from 1850 to the present day on the main atlas are entirely factual measurements, so there can be no argument on the trends. It then follows those trends into the likely scenarios for the next few years. Examining current temperature increases, it seemed to this observer that scientists have been underestimating for some time how quickly the situation is deteriorating.
