Psyche mission will visit huge metal asteroid

On Friday, a NASA spacecraft successfully began its journey to a rare and mysterious asteroid called Psyche — the largest metallic object in the Solar System. Of the million-plus asteroids in our Solar System, only a few are made mostly of metal (the rest are rock, or rock and ice). Psyche could be the exposed core of an ancient protoplanet — so it might reveal some of the secrets of Earth’s similar iron-rich core.

Hundreds of analysts get different results

More than 200 ecologists analysed the same data sets and got widely divergent results. The exercise shows that “we really can’t be relying on any individual result or any individual study to tell us the whole story”, says ecology meta researcher Hannah Fraser. None of the answers are wrong, Fraser points out — the spread of results reflects factors such as participants’ training and how they set sample sizes.

Feral horses need ‘urgent’ control

Soaring numbers of feral horses — known as brumbies — are helping to drive vulnerable species to extinction in the Australian alps, concludes a government inquiry. The report recommends reversing a ban on aerial shooting to cull horses in New South Wales — the first time that the federal government has weighed in on the issue. But it doesn’t go as far as saying that the state should repeal legislation that grants the horses protections as part of Australia’s cultural heritage.

Major US museum pledges: no more bones

The American Museum of Natural History in New York City will remove all human bones on public display as part of a pledge to address the legacy of its collection of some 12,000 human remains. This includes the bodies of Indigenous and enslaved people taken from their graves, and the remains of hundreds of New Yorkers whose bodies were given to medical schools as recently as the 1940s.

The side effects of new weight-loss drugs

Gastrointestinal problems are some of the side effects of the new hormone-mimicking anti-obesity drugs semaglutide (Ozempic and Wegovy) and tirzepatide (Mounjaro). Outside the controlled conditions of clinical trials, semaglutide increased the risk of pancreas inflammation and gastroparesis (food moving from the stomach to the intestines slower than it should) compared with an older weight-loss medication. There are concerns that tirzepatide could occasionally lead to low skeletal muscle mass that results in muscle weakness.

‘Research is too detached from our society’

“Uganda has, as a legacy of colonialism, built bits and pieces of a scientific system but it has not comprehensively linked results to socio-economic transformation,” says epidemiologist Monica Musenero. As Uganda’s science minister, she pushes for science that fixes local problems and creation of a supportive system for research, including industrial parks and national grants.

AI makes a mockery of grant applications

When robotics researcher Juan Manuel Parrilla used the artificial intelligence (AI) tool ChatGPT to write parts of a grant proposal, it cut the workload from three days to three hours. Some people might see this as cheating, Parrilla says, but it actually highlights a much bigger problem: “What is the point of asking scientists to write documents that can be easily created with AI?”

Why assembly theory got us all riled up

What is life and how did it arise? A recent paper grappled with these eternal questions using a method called ‘assembly theory’ — and kicked a hornet’s nest in the scientific community. Assembly theory is a framework for understanding how complexity and evolution emerge in nature, before biological building blocks arise. Its attempts to bridge physics and biology tap into “a longstanding tension” between the fields, writes science journalist Philip Ball. “There is an inglorious history of other scientists (physicists in particular) barging into biology only to contribute very little.”

Orange ring of an annular solar eclipse on an otherwise black background

An annular eclipse treated parts of the United States, Central America and South America to a ‘ring of fire’ as the Moon partially blocked the Sun’s light. Astronomy writer Jeff Kanipe captured this stunning image in Rio Rancho, New Mexico. (Jeff Kanipe)

Quote of the day

“It was very hard to explain to my parents what I was doing in my office on most days, which was to just sit and think and throw a lot of scratch paper into the waste basket.”

Mathematician Jang-Mei Wu is one of the ‘miracle group’ of six eminent female mathematicians, all born around 1950, who grew up during a tumultuous period in Taiwan. (Celebratio Mathematica | 32 min read)
