Massive Black Hole Mystery Solved With a Stripped Helium Star
Posted by Quinn Sena in category: cosmology
When David Poses As Goliath
Stellar black holes form when massive stars end their life in a dramatic collapse. Observations have shown that stellar black holes typically have masses of about ten times that of the Sun, in accordance with the theory of stellar evolution. Recently, a Chinese team of astronomers claimed to have discovered a black hole as massive as 70 solar masses, which, if confirmed, would severely challenge the current view of stellar evolution. The publication immediately triggered theoretical investigations as well as additional observations by other astrophysicists.
Among those to take a closer look at the object was a team of astronomers from the Universities of Erlangen-Nürnberg and Potsdam. They discovered that it may not necessarily be a black hole at all, but possibly a massive neutron star or even an ‘ordinary’ star. Their results have now been published as a highlight-paper in the renowned journal Astronomy & Astrophysics.

US Govt Warns of Attacks on Unpatched Pulse VPN Servers
Posted by Quinn Sena in categories: cybercrime/malcode, privacy
The US Cybersecurity and Infrastructure Security Agency (CISA) today alerted organizations to patch their Pulse Secure VPN servers as a defense against ongoing attacks trying to exploit a known remote code execution (RCE) vulnerability.
This warning follows another alert issued by CISA in October 2019, and others coming from the National Security Agency (NSA), the Canadian Centre for Cyber Security, and UK’s National Cyber Security Center (NCSC).
Pulse Secure reported the vulnerability tracked as CVE-2019–11510 and disclosed by Orange Tsai and Meh Chang from the DEVCORE research team, and by Jake Valletta from FireEye in an April 2019 out-of-cycle advisory.

A trippy maths program that visualises the inside of strange 3D spaces could help us figure out the shape of the universe.
Henry Segerman at Oklahoma State University and his colleagues have been working to interactively map the inside of mathematical spaces known as 3-manifolds using a program called SnapPy.

Researchers decipher a new way that immune cells detect infections and cancers
Posted by Paul Battista in categories: biotech/medical, innovation
Published today in Science, the research team from the Peter Doherty Institute for Infection and Immunity (Doherty Institute), the Olivia Newton-John Cancer Research Institute and CSL Limited say this breakthrough of discovering how gamma-delta T cells become activated addresses a question that has baffled scientists for 25 years.
The study by University of Melbourne’s Marc Rigau, Ph.D. student at the Doherty Institute, was co-led by Dr. Adam Uldrich, a Senior Research Fellow at the Doherty Institute, Professor Dale Godfrey a laboratory head at the Doherty Institute, and Dr. Andreas Behren, a Laboratory Head from the Olivia Newton-John Cancer Research Institute.
Dr. Uldrich explained that gamma-delta T cells are known to respond to the presence of small molecules, known as phosphoantigens, that are produced by bacteria and cancer cells.
