Non-invasive brain stimulation may improve mobility and stability and prevent dangerous falls in the elderly

  • One response
The researchers found that weak stimulation of the cognitive area in the brains of the elderly improves performance in a combined activity of walking/standing stable with a cognitive task. The researchers: "This is a very safe treatment, and we hope that in the future people will be able to perform it themselves at home."

The evolutionary reasons why women are colder than men

  • No comments
The researchers: "The phenomenon is not unique to humans. In many species of mammals and birds, the females prefer warm places, while the males prefer a cooler temperature." The researchers suggest that this is an inherent difference between the temperature sensing systems of the two species, which developed during evolution. The gap creates a spatial separation between males and females, which reduces competition and aggressiveness between couples

For the first time artificial intelligence for the benefit of the birds

  • No comments
Researchers at Tel Aviv University have developed a system that allows the tracking of hundreds of birds using a tiny GPS device * Thanks to the new system, the researchers were able to encourage the culture of breathing in agricultural areas, thus keeping away birds and various pests that harm the fields

The seahorses: the poor and slow swimmers are the world champions in sucking up prey

  • One response
Not only male pregnancy. The seahorses also amaze and excel in their ability to prey: during most of the day the seahorses swim in the sea with their heads tilted down and close to the body. But when they notice the prey passing over them, they raise their heads with great speed and catch it

The white blood cells may help to damage and destroy cancerous tumors

  • No comments
The researchers found that the negative destructive properties of eosinophil type white blood cells can also be used to damage and destroy cancerous tumors * The researchers discovered that eosinophils fight cancer cells in two ways: they are able to kill cancer cells directly, and also recruit T cells of the immune system that fight cancer

Algae farms in estuaries greatly reduce nitrogen concentrations and prevent environmental pollution

  • 3 תגובות
Researchers from Tel Aviv and Berkeley: The algae that grow near the mouths of rivers know how to absorb the nitrogen so that it conforms to the environmental standards and prevents its dispersion in the sea. In this way, we actually produce a kind of "natural purification facility" that has both a significant ecological value and a significant economic value

70% of the children of smoking parents suffer from forced smoking

  • No comments
The researchers tested the exposure level of the children using a biomarker - a biological marker - that measures the presence of nicotine in the hair (which indicates cumulative exposure to tobacco smoke). The findings are very worrying: among 7 out of 10 children of smoking parents who participated in the study, nicotine residues were found in the hair

Exposure to the sun's rays increases romantic desire in humans

  • One response
The researchers from Tel Aviv University discovered that exposure to the sun affects, among other things, the regulation of the sexual endocrine system (hormone secretion system) among humans.

Recordings of the magnetic field from 9,000 years ago teach us about the magnetic field today

  • 3 תגובות
Burnt flint tools from prehistoric sites make it possible to determine the strength of the Earth's magnetic field in ancient times. The information about the magnetic field in ancient times may have implications for the understanding of the magnetic field in our time. The researchers: "About 7,600 years ago the strength of the magnetic field was even lower than today, but within about 600 years the field strengthened and rose again to a high level."

For the first time in the world: XNUMXD printing of an intact and active cancer tumor

  • One response
The printed glioblastoma tumor, the deadliest type of brain cancer tumor, is printed from human tissue and contains all the components of the cancerous tumor * The researchers estimate that in the future it will be possible to quickly predict the most suitable treatment for the patient and at the same time develop new drugs at a much faster rate than what exists today

Tel Aviv's air is drinkable

A visual illustration of one of the collisions observed in the Atlas detector, and is an example of the type of processes we are looking for, and the signature they leave in our detectors. In this case a Higgs boson is created, together with another massive boson called Z (the carrier of the weak force). The blue cones and the yellow rectangles adjacent to them represent the pair of quarks into which the Higgs decayed, in this case they are of the magic type. The Z decays into two particles called muons, which can be identified by the red lines in the image. From the CERN website

For the first time, the Higgs boson was characterized by its decay into a pair of "magic" quarks

  • One response
Researchers from Tel Aviv University were able to describe for the first time a rare physical process that begins with the Higgs boson - the "divine particle" that was first observed about a decade ago - and eventually decays into a pair of rare elementary particles * New observations from the Sarn particle accelerator in Switzerland helped researchers understand the process more clearly

Bats in the city of Tel Aviv enjoy the abundance and variety of rich food that the city offers them

  • No comments
The researchers found that when fruit bats feed in the city (Tel Aviv) they are much more inquisitive, they enjoy the urban abundance, visit a variety of fruit trees every night and taste as many diverse foods as possible. In contrast, the village bats that live in Beit Govrin focus each night on only one or two fruit trees

A new immunotherapy helps the cells of the immune system locate the deadly glioblastoma brain cancer cells and eliminate them

  • No comments
The researchers relied on the CAR-T technology, which uses genetic engineering to improve the function of the immune system's T cells in their war on cancer cells. According to the researchers, the method they developed may help patients with various types of brain cancer, as well as solid tumors in other organs

Why do nerve cells die?

  • No comments
For the first time: a mechanism has been revealed that damages the nerve cells in the terminal muscular dystrophy (ALS) * CRMP4 serves as a "messenger of death" that moves along the nerve extension and kills motor neurons in the ALS disease * Rescued motor neurons in mouse models and human models of the disease

Progress in transporting drugs only to cells infected with cancer or viruses without harming healthy ones

  • One response
Prof. Dan Farr, Tel Aviv University: "Our development actually changes the world of antibodies. Today we flood the body with antibodies that are indeed selective, but also damage the healthy cells. We removed non-inflammatory cells from the game, and with a simple injection we succeeded in damaging only the inflammatory cells at that moment Given"
