A historic agreement in the field of space was signed between Israel and Azerbaijan

  • One response
Director of the Space Agency Uri Oron: "In an era in which the field of space is growing rapidly, the agreement will allow the State of Israel to have business, research and academic collaborations that are essential for the development of the space field in Israel"

The symbiosis between man and computer

The interaction between man and computer grew out of the activities of hackers in the 50s and the books and films that influenced them

Corals from the Red Sea have invaded Israel's Mediterranean coast

  • No comments
Until now, the low temperatures of the Mediterranean water in winter have been a barrier to the arrival of tropical corals. The establishment of the Dendronaphtia we found indicates that at least last winter, the waters of the Mediterranean Sea were warmer than before

Nobel Prize in Physics for 2023 to researchers who managed to measure tiny and fast processes in electrons

  • One response
The 2023 Nobel Prize in Physics was awarded to three researchers: Pierre Agostini, Ferenc Krausz and Anne L'Huillier for "the development of their methods that produce extremely short attosecond pulses of light For the study of the dynamics of electrons inside the material"
scientific picture. A XNUMXD model system of human neurons in a dish. In green and purple: nerve cells expressing a protein that is defective in the ubiquitin system. As a result of this expression, the pathology that characterizes Alzheimer's patients is created - the formation of amyloid clusters (in red) outside the cells

Technion researchers have identified the mechanism leading to the formation of protein aggregates involved in the development of Alzheimer's disease

  • One response
Toxic proteins accumulate in the brains of Alzheimer's patients. In the familial Alzheimer's patients, the accumulation mechanism is clear since there is a circumstantial relationship between the mutations and the identity of the defective proteins. In the random disease, on the other hand, the reason for the accumulation of the defective proteins was unknown

Nobel Prize in Medicine 2023 for the pioneers in the field of mRNA who accelerated the vaccines for Corona

  • No comments
Kariko and Weissman immediately realized that their discovery was of enormous significance for the possible use of messenger RNA in medicine. These important findings were published in 2005, 15 years before the outbreak of the Corona epidemic.

Nobel Prize in Medicine for discovering mRNA applications for corona vaccines

  • One response
The two, Katalin Kariko and Drew Weissman, were informed about a month ago that they had won the HARVEI Award at the Technion
The Pragyan spacecraft captured this image of the Vikram lander on August 30, before the lunar night enveloped it in its chilly darkness.

The lunar day rose, but the Indian lunar lander and rover failed to wake up

  • No comments
As the day dawned last Friday, ISRO started trying to communicate with the lander. There has been no answer so far, and it is possible that the lander and the vehicle will be buried up to about 600 km from the south pole of the moon

What is NASA planning for the ambitious Mars sample return mission?

  • No comments
In addition to bringing the first sample collected from Mars to Earth, this very complex mission will include the first launch from the soil of another planet, and also the first rendezvous in orbit around another planet. The return of the samples from Mars is a partnership with ESA (European Space Agency)
DALEE 2's interpretation of the matter of floating anti-matter atoms.

For the first time, the free fall of antihydrogen atoms was measured and the effect of gravity on antimatter was discovered

  • 3 תגובות
"This is the first measurement ever made of the free fall of antimatter (antihydrogen) atoms that directly shows that they really fall down," explained Prof. Eli Sharid from the Physics Department at Ben-Gurion University of the Negev, the member of the ALPHA collaboration group

Etrog in danger: will it be impossible to grow etrog in Israel in the future?

The etrog is currently at risk due to the rise in global temperatures as part of the climate crisis, and it is possible that the day will come when we will no longer be able to grow etrogs in Israel - for the first time in 2,500 years

Caption: Above, azobenzene is a molecule that can change its shape with light. An azobenzene molecule switches between two forms under the influence of light. In the lower figure: a molecular cage containing the molecules of the photosensitizer azobenzene. The new mechanism is based on a supramolecular approach in which the molecules of azobenzene and the photosensitizer are locked together in a molecular cage. The limited space accessible to the caged molecules allows only the E-form, but not the Z-form of azobenzene, so this molecule is pushed out of the cage. Credit: Jonathan R. Church

Publication in Science magazine about a new discovery: using harmless light to change the shape of an azobenzene molecule within a supramolecular complex

  • 2 תגובות
Azobenzenes are versatile compounds with many potential uses, such as advancing technology through the production of tiny machines, as well as creating light-activated drugs. These molecules can be found in two different forms called "E" and "Z" which can be exchanged between them through irradiation. However, under irradiation conditions both forms are in equilibrium, which prevents optimal utilization for different applications

Has a tomb of an "escort woman" (the Taira) from 2,300 years ago been discovered in Jerusalem?

  • One response
A grave in which the remains of a woman were discovered with a rare mirror next to her opens an extraordinary window into customs that were 'imported' to Israel with the Hellenistic occupation * It seems that the person buried was a young woman of Greek origin, who accompanied a senior member of the Hellenistic army or government on his journey through Israel

Are compensations sufficient for the destruction of the environment?

  • No comments
At the upcoming climate conference to be held in Dubai, ways to moderate global warming and the need to compensate the affected countries, especially island countries and countries in Africa, will be discussed again. Promises of compensation have already been given, but have not yet been fulfilled, and the question arises whether paying compensation is enough?

Parker floated through a strong coronal mass ejection that "sucked" interplanetary dust

  • No comments
"These interactions between the Sun's coronal mass ejections and interplanetary dust were theorized twenty years ago, but were not observed until the Parker Solar Probe saw that the coronal ejection acts like a vacuum cleaner, removing the dust from its orbit."
