A knifeman fatally stabbed a teacher and wounded two other people in an attack at a school in the northern France city of Arras on Friday and the investigation was handed to the anti-terrorism prosecutor's office.

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.

Point Nemo has become the final resting place for hundreds of spacecraft. What will future archaeologists make of it?

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

Neuron activity shows that the brain uses different systems for counting up to four, and for five or more.

For more than a century, researchers have known that people are generally very good at eyeballing quantities of four or fewer items. But performance at sizing up numbers drops markedly — becoming slower and more prone to error — in the face of larger numbers.

Now scientists have discovered why: the human brain uses one mechanism to assess four or fewer items and a different one for when there are five or more. The findings, obtained by recording the neuron activity of 17 human participants, settle a long-standing debate on how the brain estimates how many objects a person sees. The results were published in Nature Human Behaviour on 2 October.

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
