Chinese researchers are proposing to create tardigrade super-soldiers

Chinese researchers propose combining genes from tardigrades (water bears) to improve the ability of human cells to deal with radioactive radiation

Age slowly, live longer

A study in C. elegans worms found that a type of small RNA molecule is essential for slowing the rate of aging and prolonging the lives of animals with a damaged reproductive system

We were slaves to the ant and the butterfly

Special for Passover: It turns out that slavery is not limited to humans, and various insects survive and multiply in nature thanks to the "slavery" of other species. So what do an army of small ants and Sparta have in common? What were the ladybugs telling their psychologist? And who survives thanks to an army of drugged security guards?

Interpretation enhances reality

Psychotherapy in which the therapist also offers interpretations of behavior is more helpful in reducing depression among patients who have difficulty managing relationships

Smoking on the balcony also harms children's health

Many parents think they are protecting their children by smoking on the balcony or near the bedroom window. But a new study by Tel Aviv University states that contrary to the popular opinion of those parents, restricting smoking to the balcony does not prevent the exposure of most children to the harm of tobacco smoke

A worldwide breakthrough states: plants make sounds

Each plant and each type of distress has a characteristic, recognizable sound. The sounds of plants sound like clicks, like popcorn, at a volume similar to human speech but at frequencies above the human hearing range, and they may be picked up by various animals, such as bats, mice and insects

Researchers succeeded in cracking the formation mechanism of 'microsomes'

  • No comments
Microsomes are recently discovered cellular organelles that are formed by local swelling of membrane fibers formed during cell migration. The microsomes store intracellular biomolecules such as DNA, RNA, proteins and even whole organelles such as the mitochondria and affect the intercellular communication

By using an innovative microscope, they were able to identify for the first time the process in which the seashell produces crystals used for vision, and discovered that it is similar to the process of the formation of freckles in humans

Dolphin, do you like fishing?

For several decades dolphins and fishermen have been hunting together on the beaches of southern Brazil. A new international study reveals how this cooperation contributes to the marine mammals' chances of survival and what we must do so that it does not disappear from the world

Positive emotion to reduce negative emotion

It turns out that when people are sad, they choose more actions that cause pleasure, and when they feel shame, they choose more actions that cause pride

The survey telescope with the largest field of view in the world was inaugurated these days in Arava

The director of the observatory, Dr. David Polischuk from the Weizmann Institute, says in an interview to the site of the scientist that the telescope is actually an array of 48 small telescopes that together give the opportunity to observe an extremely wide field of view in order to locate planets, supernovae, sources of gravitational waves and more

The heavy price that corals may pay due to climate change

  • No comments
Global warming affects life in the sea in many ways when it causes a decrease in dissolved oxygen in the ocean water on the one hand, and on the other hand, an increase in the metabolism of marine animals, which further increases their need for oxygen

Mice with two fathers: Scientists create eggs from male cells

  • 2 תגובות
The researchers behind the new study were able to create baby mice with genetic material from two males without any genetic changes. They achieved this by using stem cells to create primordial germ cells (PGCs), which differentiate into sperm and egg.

Genomic study of ancient human remains sheds light on human evolution at the Tibetan plateau

  • No comments
Beginning 4,500 years ago, three very different Tibetan populations occupied the northeastern, south-central, and southern and southwestern regions of the plateau, but they carry a common gene that allows them to function in high, low-oxygen areas. This gene may have come from Denisovan man

Scientific breakthrough: for the first time in the world an mRNA vaccine against deadly bacteria

Researchers succeeded for the first time in the world in developing a vaccine against a deadly bacterium, opening the door to mRNA vaccines also against antibiotic-resistant bacteria

Researchers at the Hebrew University and the University of Kentucky believe that a specific type of protein, which has not been studied before, substantially increases the molecular complexity in the brain and improves its function. "Such a discovery may have implications for the study of neurological diseases such as schizophrenia, epilepsy and autism"
