The war on the hive: how do the fires affect the bee population in Israel?

Following the severe fires in the north, the beehives were also damaged - what might be the cost of the damage and is there anything that can be done to restore them?

The strange story of Yakinaf the mammoth - maybe she will come back to life

Prof. George Church is trying to clone a woolly mammoth that was trapped in the Siberian ice 52 thousand years ago
An electron microscope image of phages that replicated inside bacterial cells that possess the immune system discovered in the study. The immune system attached a ubiquitin-like protein (marked with black dots and white arrows) to the tails of the phages, thus preventing them from infecting additional bacterial cells

to the tail of viruses

Weizmann Institute of Science scientists have discovered a bacterial immune system that "neuters" the tails of viruses. The new system is based on a protein previously discovered by Nobel laureates Avraham Hershko and Aharon Chachanover

The fertilized egg and its war in patriarchy

If you asked yourself why we only inherit the mitochondria from the mother, the answer is - the egg is the one that destroys the father's mitochondria very shortly after fertilization

between the muscles and the skeleton

Researchers discovered that in mice lacking a protein that is responsible for muscle contraction, fusion developed between the vertebrae of the spine, which may lead to scoliosis and other orthopedic diseases

How might a biochip save us from the next pandemic

  • No comments
Cornell University has introduced a bioelectric device that can quickly detect harmful variants of Corona, and possibly other viruses as well. This chip-based device uses a biomembrane to simulate the process of infection development
Cells with cancerous p53 proteins (in red), in the presence of the accompanying protein DNAJA2 (left) and in the presence of its version without a "hairpin" (right). In its presence, the structure of the cancerous proteins is stabilized and they do not stick to each other and therefore remain scattered throughout the cell. In its absence, the cell is not colored red since the proteins form aggregates (red dots) that the cell can recognize and destroy (in blue - the genetic material in the cell nuclei)

stick a pin in the tumor

Weizmann Institute of Science scientists have discovered a new cellular mechanism for identifying proteins whose 3D structure has been unraveled, thereby revealing a targeted target for cancer treatment

Anticoagulant proteins show promise in preserving organs for transplantation

  • No comments
A joint study by researchers from the Technion Hebrew University and the Weizmann Institute examined the possibility of incorporating anticoagulants into organs intended for transplantation to prevent damage to the organ and to cancel the transplant, as well as to help preserve organs for a longer period of time

New insights about Parkinson's disease - and the meaning for medicine

In recent years it turned out that long before the first symptoms of Parkinson's appear, it is possible to find a change in the population of intestinal bacteria of the patients

A snail without limits

  • One response
The 'pipe builder' snail was awarded the title of 'environmental engineer', in light of its contribution to the construction of rocky surfaces on the coastline and reducing their rate of weathering in an effective way. It came to the brink of extinction, but researchers from Ben Gurion University succeeded

Today, it is possible to produce a small number of breast milk oligosaccharides with the help of transgenic E. coli bacteria. However, isolating the beneficial molecules from other toxic products is an expensive process, and only a limited number of
