Spiral Spectacle: Hubble Explores a Cosmic Marvel in the Virgo Cluster

Posted by in category: space

NGC 4,731, a barred spiral galaxy in the Virgo cluster, is this week’s Hubble Picture of the Week. Featuring detailed colors and structures, the galaxy’s study may help explain how its bar and spiral arms influence star formation and matter dynamics.

This Hubble Space Telescope image features the broad and sweeping spiral galaxy NGC 4731. This galaxy lies among the galaxies of the Virgo cluster, in the constellation Virgo, and is located 43 million light-years from Earth.

This highly detailed image was generated by using six different filters. The abundance of color illustrates the galaxy’s billowing clouds of gas, dark dust bands, bright pink star-forming regions and, most obviously, the long, glowing bar with trailing arms.

New study shows urolithin A can improve treatment of Alzheimer’s

Posted by in categories: biotech/medical, neuroscience

The research team found that long-term urolithin A treatment in mice significantly improved their learning, memory and olfactory function. The treatment also reduced amyloid beta (Aβ) and tau pathologies and improved cellular lysosomal function [1].

The researchers’ findings also suggest that urolithin A is as effective as NAD in promoting mitophagy, positioning it as a potential therapeutic agent for Alzheimer’s disease.

“Our study on mouse models with AD shows that urolithin A, which is a naturally occurring substance in pomegranates, can alleviate memory problems and other consequences of dementia,” says Bohr. “Even though the study was conducted on mouse models, the prospects are positive. So far, research has shown promising results for the substance in the muscles, and clinical trials on humans are being planned [3].”

Hackers target Check Point VPNs to breach enterprise networks

Posted by in category: security

Threat actors are targeting Check Point Remote Access VPN devices in an ongoing campaign to breach enterprise networks, the company warned in a Monday advisory.

Remote Access is integrated into all Check Point network firewalls. It can be configured as a client-to-site VPN for access to corporate networks via VPN clients or set up as an SSL VPN Portal for web-based access.

Check Point says the attackers are targeting security gateways with old local accounts using insecure password-only authentication, which should be used with certificate authentication to prevent breaches.

Quantum ‘arrow of time’ suggests early universe had no entanglement

Posted by in category: quantum physics

One way to explain why time only moves forward is the quantum arrow of time, and it has major implications for both the universe’s early period and its eventual demise.

Computer scientists discover Vulnerability in Cloud Server Hardware used by AMD and Intel Chips

Posted by in categories: computing, security

Public cloud services employ special security technologies. Computer scientists at ETH Zurich have now discovered a gap in the latest security mechanisms used by AMD and Intel chips. This affects major cloud providers.

Over the past few years, hardware manufacturers have developed technologies that ought to make it possible for companies and governmental organizations to process sensitive data securely using shared cloud computing resources.

Known as confidential computing, this approach protects sensitive data while it is being processed by isolating it in an area that is impenetrable to other users and even to the cloud provider. But computer scientists at ETH Zurich have now proved that it is possible for hackers to gain access to these systems and to the data stored in them.

Researchers discover a “fossil cloud” that hasn’t been contaminated since the Big Bang

Posted by in categories: cosmology, materials

Making use of some of the most powerful telescopes on the planet, astronomers have found an ancient remnant of the Big Bang. This small piece of pure material from the early universe may provide light on the processes and motivations behind the formation of various star and galaxy types.

Using telescopes at the W. M. Keck Obervatory in Hawaii, a team of astronomers led by Fred Robert and Michael Murphy of the Swinburne University of Technology in Australia discovered a cloud of gas leftover from the Big Bang that was hiding far out in the universe. Behind the cloud, the telescope also discovered a quasar, which is an extremely bright active galactic nucleus that emits a lot of energy.
