A person received a pig kidney - with 69 genetic changes

The changes are intended to prevent the body from becoming infected with dormant viruses that may be present in the kidney, and in any case the kidney is designed to fit the specific patient

As part of the Teva-Biz project shared by the Ministry of Environmental Protection and the Society for the Protection of Nature, a nature survey was conducted for the first time in Naot Smadar where the new dragonfly was discovered
The polymer conjugated to the peptide and the drug (P-Esbp-DOX) binds to the E-selectin protein, which is expressed on the surface of endothelial cells that line the blood vessels in the tumor environment, enters the cells, releases the drug inside them and kills them.

inhibit the migration of cancer cells

Researchers have developed polymers that bind to proteins that play a key role in cancer and inflammation, thus preventing - in mice - the formation of metastases and slowing down the progression of arteriosclerosis and hepatitis

New findings regarding the connection between the increase of oxygen in the atmosphere and the development of complex life

  • No comments
Hebrew University researchers have revealed new findings regarding the connection between the increase in oxygen in the atmosphere and oceans on Earth, and the development of complex life. The study indicates that the rise of oxygen occurred after the development of complex life, contrary to previous assumptions

Glowing Botany: Glow-in-the-dark petunias are coming to cities

The Light Bio company has developed petunia plants that contain a lighting garden of fireflies. Will they give up the street lights?
Muscle in the making: stem cells of muscle tissue (their nuclei are marked in blue) gradually change their structure and function and become mature muscle cells (the cells whose nuclei have turned red). These cells will eventually fuse into one long, multinucleated muscle cell. The ability of this muscle to contract is thanks to a large number of protein fibers produced in the mature muscle cells (marked in green)

How a muscle is born

An artificial intelligence model sheds light on the specialization pathway of muscle cells and reveals an important control node along the way

The race to the top of the wild mouse

Research in field mice under conditions simulating a natural environment reveals the different strategies used by females and males in creating social hierarchies
The cover photo on the issue: Cell Host & Microbe This is how the bacteriophages (in purple) affect the function of the bacteria by reversing the DNA - a reversal that changes their effect on the immune system. This effect is demonstrated by changing the color of the bacteria from yellow to green. Illustration credit: Tomm Blum

Gut bacteria are able to change their 'software' in response to inflammation, which may affect the immune system

The intestine is a very dynamic organ that is constantly changing structurally, mechanically and chemically, and the intestinal bacteria are required to cope with this dynamism. One of the features that may help them in this is plasticity - the ability to undergo rapid genomic changes in response to changes in environmental conditions

Unlike the 2017 eclipse that occurred in August, this eclipse occurs when the spring migration is already underway. And since most birds fly at night, a solar eclipse may affect them significantly

With the help of artificial intelligence: an effect of ship noise on dolphins was found for the first time

  • No comments
According to the researchers, the dolphins communicate in a different way and change their vocal behavior when they encounter the noise of a ship and therefore they are definitely affected by the noise of the ships. Past studies have already shown that a change in vocal behavior can be related to stress and distress
