Unnamed octogenarian may have survived a failed infanticide attempt by her parents.

Doctors found an 80-year-old woman in Russia has lived her entire life with an inch-long needle in her brain.

A local radiologist discovered a three-centimetre needle inside the octogenarian’s brain during an X-ray scan, said the Ministry of Health in Sakhalin in a Telegram post on Wednesday.

The tiny needle was located in the parietal lobe of the unnamed woman’s brain, according to the ministry. While it did not disclose the exact date of discovery, it said the needle was found this year.

The needle was lodged inside her brain since she was born. Doctors believe she had survived a failed infanticide attempt by her parents.

Today, ESA's Gaia mission releases a goldmine of knowledge about our galaxy and beyond. Among other findings, the star surveyor surpasses its planned potential to reveal half a million new and faint stars in a massive cluster, identify over 380 possible cosmic lenses, and pinpoint the positions of more than 150 000 asteroids within the Solar System.

Spring is a dangerous time to be a female European common frog. After a winter-long hibernation, these amphibians congregate in shallow ponds to mate and lay eggs. The gatherings can turn ugly fast; male frogs, which vastly outnumber females, will regularly harass, intimidate, and coerce their counterparts into mating.

Scientists have long assumed the females have little means of defending themselves. But they may be less helpless than previously thought. Today in Royal Society Open Science, researchers report that female European common frogs (Rana temporaria) have a few tricks to escape unwanted mating, including duping a ribbiting Romeo into thinking he’s encountered another male, wriggling out of his grasp, or even playing dead.

Traditional medical imaging works great for people with light skin but has trouble getting clear pictures from patients with darker skin. A Johns Hopkins University–led team found a way to deliver clear pictures of anyone's internal anatomy, no matter their skin tone.

In experiments the new imaging technique produced significantly sharper images for all people—and excelled with darker skin tones. It produced much clearer images of arteries running through the forearms of all participants, compared to standard imaging methods where it was nearly impossible to distinguish the arteries in darker-skinned individuals.

As industry steps aside, scientists seek innovative ways to make sure expensive treatments can reach people who need them.

An annular solar eclipse, also known as a “ring of fire” eclipse because of the way the sun and moon line up, will be visible in the US, Central America and South America on 14 October

Last year, lawmakers in the United States passed bipartisan legislation intended to maintain US competitiveness with countries such as China by boosting funding for science and innovation. But concerns are mounting that the US Congress will fail to deliver on its promises.

The money allotted to a handful of major US science agencies that had been targeted for a budget boost is likely to fall short of the legislation’s goals by more than US$7 billion in 2024, according to a report. And overall funding for those agencies will continue to hover at a 25-year low

Japanese scientist Kikunae Ikeda first proposed umami as a basic taste — in addition to sweet, sour, salty and bitter — in the early 1900s. About eight decades later, the scientific community officially agreed with him.

Now, scientists led by researchers at the USC Dornsife College of Letters, Arts and Sciences have evidence of a sixth basic taste.

In research published Oct. 5 in Nature Communications, USC Dornsife neuroscientist Emily Liman and her team found that the tongue responds to ammonium chloride through the same protein receptor that signals sour taste.
