June 10, 2024
Like treetops reaching high into the sky to sense the sunlight, our sensory neurons – whose role is to collect information about what is happening in and around the body – grow long, intricate extensions known as axons. These extensions spread out throughout the body, conveying v...

June 18, 2024
Just a few years ago, we could hardly have imagined that millions of people around the world would have access to easy-to-use generative AI applications that produce texts, images and videos. These apps can generate outputs that look as if they were created by human beings, as we...

June 23, 2024
Pancreatic cancer is difficult to detect, in part because the pancreas sits deep in the abdominal cavity in a position that can vary from person to person; pancreatic tumors therefore can remain hidden until too late for treatment. Now, researchers at the Weizmann Institute of Sc...

“Who will watch the watchers?” asked Roman poet Juvenal way back in the first century C.E. Nature has been addressing that very question for much, much longer. The human body contains proteins that are designed to protect us from cancerous growths. Like most proteins, to do their...

July 15, 2024
Within minutes of fertilization, the egg of a fruit fly becomes a scene from the battle of the sexes. The egg attacks and destroys the cellular “power plants,” or mitochondria, from the sperm that had fertilized it, so that only its own mitochondria remain. These findings from a...

July 17, 2024
Phages, viruses that attack bacteria, have a head and a tail. The head contains the phage’s genetic material and the tail is used to identify a potential host, that is, a bacterial cell into which it can inject this material. Once the injection is complete, the phage hijacks the...

July 31, 2024
The nose is a major gateway to our bodies – for the air we breathe, the aromas we smell and the microbes that make us sick. On its way in, the air passes through nasal conchae, or turbinates – the long, narrow, curled shelves of bone that look like a shell and protrude into the b...

Tourists visiting an unfamiliar city would have a hard time finding their way around if they were using nothing but a topological map, no matter how detailed. Most tourist maps, therefore, highlight sights of interest and prominent landmarks. As far back as the 16th century, we w...

August 15, 2024
Mescaline, a natural hallucinogen known since ancient times, was not only a favorite of artists and bohemians but also a mainstay of brain research throughout the first half of the 20th century, until it was eclipsed in the 1950s by the much more potent, synthetic LSD. Now, with...

August 20, 2024
When two particles collide, they normally fly off in opposite directions, like billiard balls on a smooth table. But in a recent physics experiment at the Weizmann Institute of Science, instead of flying off, the particles seemed to engage in a sort of a post-collision billiard-b...
