Science Tips, November 2014

https://www.weizmann-usa.org/news-media/news-releases/science-tips-november-2014/

Nov 18, 2014... Satellite image of Olympus Mons on Mars, the largest volcano in the solar system at about three times the height of Mount Everest. Around 3.5 to 4 billion years ago, the release of volcanic gases, especially the greenhouse gas sulfur dioxide, may have warmed the surface of Mars episodically, melting the ice and thereby explaining the presence of geomorphological features indicative of the flow of water on the planet’s ancient surface.

COVID Moonshot: Can AI Algorithms and Volunteer Chemists Design a Knockout Antiviral?
COVID Moonshot: Can AI Algorithms and Volunteer Chemists Design a Knockout Antiviral?

https://www.weizmann-usa.org/news-media/in-the-news/covid-moonshot-can-ai-algorithms-and-volunteer-chemists-design-a-knockout-antiviral/

May 08, 2020... It started with a tweet. Alpha Lee, co-founder and chief scientific officer of machine-learning company PostEra, read on Twitter that Diamond Light Source, the UK’s national synchrotron facility, had identified a set of chemical fragments that attach to an important coronavirus protein.
Lee wondered if his company, formed just six months earlier, could help connect the dots from fragments to viable drugs to fight COVID-19. PostEra uses AI algorithms to map routes for drug synthesis to speed the drug discovery process. But to do so, they would need some design ideas. So Lee asked the Internet.

The Self-Synthesizing Ribosome
The Self-Synthesizing Ribosome

https://www.weizmann-usa.org/news-media/news-releases/the-self-synthesizing-ribosome/

Apr 20, 2020... REHOVOT, ISRAEL—April 20, 2020—As the cell’s protein factory, the ribosome is the only natural machine that manufactures its own parts. That’s why understanding how the machine itself is made could unlock the door to everything from understanding how life develops to designing new methods of drug production. An intensive research effort at the Weizmann Institute of Science has now demonstrated the self-synthesis and assembly of the small subunit of a ribosome – 30S – on a surface of a chip. The findings were published in Science Advances.

Mar 30, 2020... In this videoconference presentation, Dr. Nir London of the Weizmann Institute’s Department of Organic Chemistry describes what he calls the “COVID Moonshot.” The project is co-led by Frank van Delft of Oxford University and Diamond Light Source (the U.K.’s synchrotron science facility), who was also on the call. Dr. London discusses various approaches to coronavirus, including the value of standard approaches such as vaccines and antivirals.

https://www.weizmann-usa.org/news-media/in-the-news/could-the-flu-become-history-an-israeli-vaccine-may-make-it-a-reality/

May 06, 2020... A year and a half ago, biochemist Prof. Ruth Arnon, Israel Prize recipient for medicine and past president of the Israel Academy of Sciences and Humanities, received an email from the editor of a science journal. The editor asked whether she planned to attend a conference on multiple sclerosis that was to take place a few days later. Arnon, who was one of the scientists responsible for the research that led to the MS treatment, Copaxone, said she wouldn’t be attending, but was sending a researcher from her lab at the Weizmann Institute of Science.

Jun 22, 2020... REHOVOT, ISRAEL—June 22, 2020—What did the very first proteins – those that appeared on Earth around 3.7 billion years ago – look like? Prof. Dan Tawfik of the Weizmann Institute of Science and Prof. Norman Metanis of the Hebrew University of Jerusalem have reconstructed protein sequences that may well resemble those ancestors of modern proteins, and their research suggests a way that these primitive proteins could have progressed to forming living cells. Their findings were published in the Proceedings of the National Academy of Sciences (PNAS).

Jun 25, 2020... The question as to how life began on Earth is one of the most fundamental to science, yet it remains one of humanity’s great mysteries. The first cells emerged relatively quickly after the Earth formed, meaning life wasted no time getting started once it had the right ingredients. Yet even the simplest cell is a complex bags of organelles, proteins, lipids and other molecular parts — and no one knows quite how such a complicated thing formed from random, inorganic processes.

Artificial Cells Produce Parts of Viruses for Safe Studies
Artificial Cells Produce Parts of Viruses for Safe Studies

https://www.weizmann-usa.org/news-media/news-releases/artificial-cells-produce-parts-of-viruses-for-safe-studies/

Jul 20, 2020... REHOVOT, ISRAEL—July 20, 2020—Scientists searching for better diagnostic tests, drugs, or vaccines against a virus must begin by deciphering the structure of that virus. And when the virus in question is highly pathogenic, such research can be quite dangerous. Prof. Roy Bar-Ziv of the Weizmann Institute’s Department of Materials and Interfaces; staff scientist Dr. Shirley Shulman Daube; Dr. Ohad Vonshak, a former research student in the Bar-Ziv lab; and current research student Yiftach Divon have an original solution to this obstacle. They demonstrated the production of viral parts within artificial cells.

Aug 13, 2020... Prof. Eran Hornstein, a member of the steering committee for Weizmann’s new Institute for Brain and Neural Sciences, discusses this important flagship project, which will bring together experts in multiple disciplines to understand mental illness, advance treatments for diseases like Alzheimer's and Parkinson's, and much more. He explains why Weizmann is in an ideal position to uncover the brain's mysteries, with more than 40 internationally renowned research groups dedicated to addressing the most pressing topics in neuroscience.
