In Einstein’s theory of general relativity, gravity arises when a massive object distorts the fabric of spacetime the way a ball sinks into a piece of stretched cloth. Solving Einstein’s equations by using quantities that apply across all space and time coordinates could enable physicists to eventually find their “white whale”: a quantum theory of gravity.

In a new article in The European Physical Journal H 0, Donald Salisbury from Austin College in Sherman, USA, explains how Peter Bergmann and Arthur Komar first proposed a way to get one step closer to this goal by using Hamilton-Jacobi techniques. These arose in the study of particle motion in order to obtain the complete set of solutions from a single function of particle position and constants of the motion.

Three of the four fundamental forces —strong, weak, and electromagnetic—hold under both the ordinary world of our everyday experience, modeled by classical physics, and the spooky world of quantum physics. Problems arise, though, when trying to apply to the fourth force, gravity, to the quantum world. In the 1960s and 1970s, Peter Bergmann of Syracuse University, New York and his associates recognized that in order to someday reconcile Einstein’s theory of general relativity with the quantum world, they needed to find quantities for determining events in space and time that applied across all frames of reference. They succeeded in doing this by using the Hamilton-Jacobi techniques.

Webb was expected to merely confirm the Standard Model of the universe but its images are “surprisingly smooth, surprisingly small and surprisingly old.”

Over its 23-year lifetime, the station has been an important example of how Russia and the United States can work together despite being former adversaries. This cooperation has been especially significant as the countries’ relationship has deteriorated in recent years. While it remains unclear whether the Russians will follow through with this announcement, it does add significant stress to the operation of the most successful international cooperation in space ever. As a scholar who studies space policy, I think the question now is whether the political relationship has gotten so bad that working together in space has become impossible.

Russia operates six of the 17 modules of the ISS — including Zvezda, which houses the main engine system. This engine is vital to the station’s ability to remain in orbit and also to how it moves out of the way of dangerous space debris. Under the ISS agreements, Russia retains full control and legal authority over its modules.

It is currently unclear how Russia’s withdrawal will play out. Russia’s announcement speaks only to “after 2024.” Additionally, Russia did not say whether it would allow the ISS partners to take control of the Russian modules and continue to operate the station or whether it would require that the modules be shut down completely.

Iron will be key to human self-sufficiency on Mars.

When the first humans reach Mars, they’ll probably live in habitats that were there ahead of time or in habitats made from their landers.

A landmark study that came out in 2005 showed that if you fused the blood systems of old and young mice, a process known as heterochronic parabiosis, it rejuvenated the cells of old mice. It suggested that there was something in the blood and there were two possible explanations; there were rejuvenating factors in the young blood, or there was dilution of pro-aging factors in the old blood. Or some combination of both.

Artificial intelligence has mostly been focusing on a technique called deep learning. It might be time to reconsider.

The seeds of innovation appear to be seedless. According to game-changing research led by our very own Dr. Lior Rubinovich, it is now finally possible to grow avocado plants solely from tissue culture. Why is this good? Aside from being free of deformities, disease-proof, and significantly fast-growing – cultivated avocado plants mean genetic uniformity, which implies that all plants originate from the same delicious, nutritious, and healthy tissue. The founding of Bestree means a great deal for the northern region of Israel, both financially and innovatively. Therefore, we are proud to share this inspiring research with the rest of the world!

האם ניתן לרבות שתילי אבוקדו בתרביות ריקמה? עד לפני כמה חודשים התשובה הייתה: “אולי, אבל טרם הצלחנו להבין כיצד לעשות זאת” היום התמונה היא אחרת, בעקבות מחקרו פורץ הדרך של ד“ר ליאור רובינוביץ’ הפך אבוקדו שמיוצר בתרבית ריקמה לרעיון שלא רק ניתן ליישמו במעבדה אלא גם למסחרו ולהביאו כבשורה לחקלאות העולמית! זהו פיתוחה וחזונה של חב’ Bestree אשר הוקמה על בסיס מחקרו של רבינוביץ’ ונחנכה בטקס חגיגי בקיבוץ אל-רום שבגליל. מעבר ליתרונות השיווקיים והכלכליים של המהלך – הקמתה של חב’ Bestree שמה את מיגל בשורה הראשונה של מכוני מחקר בעולם ובכך מקדמת גם את הפיתוח וההתחדשות החקלאית והמדעית של צפון מדינת ישראל! לחצו לקריאה מורחבת אודות חב’ Bestree https://www.ice.co.il/media/news/article/876527
