Galaxy formation simulated without dark matter

Posted by in categories: computing, cosmology

For the first time, researchers from the Universities of Bonn and Strasbourg have simulated the formation of galaxies in a universe without dark matter. To replicate this process on the computer, they have instead modified Newton’s laws of gravity. The galaxies that were created in the computer calculations are similar to those we actually see today. According to the scientists, their assumptions could solve many mysteries of modern cosmology. The results are published in the Astrophysical Journal.

Cosmologists today assume that matter was not distributed entirely evenly after the Big Bang. The denser places attracted more matter from their surroundings due to their stronger gravitational forces. Over the course of several billion years, these accumulations of gas eventually formed the galaxies we see today.

An important ingredient of this theory is the so-called . On the one hand, it is said to be responsible for the initial uneven distribution that led to the agglomeration of the gas clouds. It also explains some puzzling observations. For instance, stars in rotating galaxies often move so fast that they should actually be ejected. It appears that there is an additional source of gravity in the galaxies that prevents this—a kind of “star putty” that cannot be seen with telescopes: dark matter.

Information theft via manipulating screen brightness in air-gapped computers

Posted by in categories: computing, internet, security, surveillance

Data can be stolen from an air gapped personal computer just by using variations in screen brightness. Researchers at Ben-Gurion University wrote a paper on it.

As the team defines them, “Air-gapped computers are systems that are kept isolated from the Internet since they store or process .”

Scientists race to develop vaccine for new coronavirus

Posted by in category: biotech/medical

Scientists from the United States to Australia are using new technology in an ambitious, multi-million-dollar drive to develop a vaccine in record time to tackle China’s coronavirus outbreak.

The has spread rapidly since emerging late last year in China, killing more than 800 people in the mainland and infecting over 37,000. Cases have been reported in two dozen other countries.

Coming up with any vaccine typically takes years, and involves a lengthy process of testing on animals, on humans and regulatory approvals.

Eyes to the skies: Rocket launch to be visible in DC region

Posted by in categories: space, transportation

NASA Wallops Flight Facility is scheduled to launch a rocket tonight that will be visible to the DMV as it climbs into the sunset sky.

The facility hopes to launch the 13th Northrop Grumman resupply mission to the International Space Station (ISS) at 5:39 p.m. near sunset. The Cygnus cargo ship (spacecraft) is the S.S. Robert H. Lawrence, named for the first ever African American selected as an astronaut.

The launch and mission will be carried live by NASA.
