Small proteins discovered to be regulators of the aging process

Small proteins discovered to be regulators of the aging process

Scientists have discovered that the protein ubiquitin plays an important role in the regulation of the aging process. Ubiquitin was previously known to control processes such as signal transduction and metabolism. Prof. Dr. David Vilchez and his colleagues at the CECAD Cluster of Excellence for Aging Research at the University of Cologne performed a comprehensive quantitative analysis of ubiquitin signatures during aging in the model organism Caenorhabditis elegans, a nematode worm broadly used for aging research. This method—called ubiquitin proteomics—measures all changes in ubiquitination of proteins in the cell. The resulting data provide site-specific information and define quantitative changes in ubiquitin changes...

Metallic water created for the first time in golden experiment

      Researchers have created metallic water for the first time. Through a very careful experimental setup, the team grew a thin layer of a gold-colored metallic water on the outside of a droplet of liquid metal. It may be surprising for most people to find out that water is actually an insulator – at least when it’s perfectly pure. The stuff that comes out of the tap, however, is a well-known conductor of electricity, due to the salts and impurities it contains. But making pure water metallic, or conductive, has long been a scientific challenge. But now, a...

Laser pincers generate antimatter by recreating neutron star conditions

Laser pincers generate antimatter by recreating neutron star conditions

Physicists have simulated how to create antimatter in the lab by firing two lasers at a plastic block   Some of the greatest mysteries in cosmology revolve around antimatter, and it’s hard to study because it’s rare and hard to produce in the lab. Now a team of physicists has outlined a relatively simple new way to create antimatter, by firing two lasers at each other to reproduce the conditions near a neutron star, converting light into matter and antimatter. In principle, antimatter sounds simple – it’s just like regular matter, except its particles have the opposite charge. That basic...

Meet the Quiet Tech Revolutionary Who’s Leading the Charge to Make Electric Flight a Reality

Meet the Quiet Tech Revolutionary Who’s Leading the Charge to Make Electric Flight a Reality

JoeBen Bevirt has ducked the media spotlight—until now. He discusses how electric air taxis will make urban transport cleaner and cheaper. The most recognizable name in the emerging electrical vertical takeoff and landing (eVTOL) segment, JoeBen Bevirt, broke years-long silence yesterday during a webcast with the Washington Post.  It turns out he didn’t reveal any new details about his four-passenger electric aircraft or specifically where his company, Joby Aviation, is heading. He did, however, provide a general roadmap of how he thinks electric aviation will cause a transportation revolution.    Bevirt received Robb Report’s 2021 Best of the Best “One to Watch” award for his leadership and vision...

Steel Giant ArcelorMittal To Produce Green Steel By 2025

Steel Giant ArcelorMittal To Produce Green Steel By 2025

Steel Giant ArcelorMittal is making the transition from coal to green hydrogen, saving millions of tons of CO2 each year.       Over 1.8 billion tons of steel are produced annually worldwide, releasing nearly double that in carbon dioxide into the atmosphere. As a result, the industry accounts for 7% to 8% of global carbon emissions per year. But the world can’t get by without this ever-present metal anymore. Hence, it’s a key target in the race to net-zero by 2050. The problem with steelmaking is that about 75% of the energy used to make it comes from coal. For example,...
