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.

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.

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.

Euclid has found its ‘lost’ guide stars as a software patch has solved its navigation woes and the next six years of observation schedules have been redesigned to avoid stray sunlight: it’s the end of an interesting commissioning phase and Euclid will now undergo its final testing in full ‘science mode’.

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.

Lions have long been perceived as Africa’s, if not the world’s, most fearsome terrestrial predator,the “king of beasts”. Wildlife’s fear of humans may, however, be far more powerful and all-prevailing, as recent global surveys show that humans kill prey at much higher rates than other predators, due partly to technologies such as hunting with dogs or guns.

The class action will be decided by a single judge and could be a ‘genuine problem for Monsanto and Bayer if we’re successful’, lawyer says

In a study on the prevalence of attention-deficit/hyperactivity disorder (ADHD) and its association with crash risk among older adult drivers, researchers at Columbia University Mailman School of Public Health found that older adult drivers with ADHD are at a significantly elevated crash risk compared with their counterparts without ADHD. Outcomes included hard- braking events, and self-reported traffic ticket events, and vehicular crashes.

Until now research on ADHD and driving safety was largely limited to children and young adults, and few studies assessed the association of ADHD with crash risk among older adults. The results are published online in JAMA Network Open.

To date it has been unclear exactly how the sex of a bee is determined. A research team from Heinrich Heine University Düsseldorf (HHU) comprising biologists and chemists has now identified a key gene and the molecular mechanism linked with it. In the current issue of the scientific journal Science Advances, they describe how this process is similar to a game involving two dice.

The novel class of optical modulators can make data transfer over optical fiber communication faster and more efficient.

Whether you’re battling foes in a virtual arena or collaborating with colleagues across the globe, lag-induced disruptions can be a major hindrance to seamless communication and immersive experiences.

That’s why researchers with UCF’s College of Optics and Photonics (CREOL) and the University of California, Los Angeles, have developed new technology to make data transfer over optical fiber communication faster and more efficient.
