We Finally Know How Black Holes Produce The Most Brilliant Light in The Universe

Posted by in categories: cosmology, materials

For something that emits no light that we can detect, black holes just love to cloak themselves in radiance.

Some of the brightest light in the Universe comes from supermassive black holes, in fact. Well, not actually the black holes themselves; it’s the material around them as they actively slurp down vast amounts of matter from their immediate surroundings.

Among the brightest of these maelstroms of swirling hot material are galaxies known as blazars. Not only do they glow with the heat of a swirling coat, but they also channel material into ‘blazing’ beams that zoom through the cosmos, shedding electromagnetic radiation at energies that are hard to fathom.

Could this new ultrasound change the way cancer is treated? — BBC News

Posted by in category: biotech/medical

A new cancer treatment which destroys tissue non-invasively is being trialled, and, if it gains regulatory approval, it could change the way that cancers are treated in hospitals.

Histotripsy is a type of focused ultrasound which, unlike heat and radiation based treatments, is more precise – which makes it a more appealing treatment option for smaller and widespread tumours.

Inspired by Manta Ray Biomechanics: “Butterfly Bot” Is Fastest Swimming Soft Robot Ever

Posted by in category: robotics/AI

Researchers have developed an energy-efficient soft robot that can swim more than four times faster than previous swimming soft robots by taking inspiration from the biomechanics of the manta ray. Developed at North Carolina State University.

Founded in 1,887 and part of the University of North Carolina system, North Carolina State University (also referred to as NCSU, NC State, or just State) is a public land-grant research university in Raleigh, North Carolina. It forms one of the corners of the Research Triangle together with Duke University in Durham and The University of North Carolina at Chapel Hill.

Israeli company unearths rare mineral

Posted by in categories: business, space travel

A post was reported and I checked it. My business is minerals, and I had heard of the discovery before so I kept the post. Here is information from BBC to back it up.

Carmeltazite was added to the official list of known minerals this week after being approved by the International Mineralogical Association (IMA).

Taub Avi, CEO of the precious stone exploration company Shefa Yamim, said it was discovered by the company in volcanic rock in northern Israel’s Sevulun Valley.

Dell, HP, and Lenovo Devices Found Using Outdated OpenSSL Versions

Posted by in category: computing

An analysis of firmware images across devices from Dell, HP, and Lenovo has revealed the presence of outdated versions of the OpenSSL cryptographic library, underscoring a supply chain risk.

EFI Development Kit, aka EDK, is an open source implementation of the Unified Extensible Firmware Interface (UEFI), which functions as an interface between the operating system and the firmware embedded in the device’s hardware.

The firmware development environment, which is in its second iteration (EDK II), comes with its own cryptographic package called CryptoPkg that, in turn, makes use of services from the OpenSSL project.

Scientists Discover a Link Between Mitochondria and Cancer

Posted by in categories: biotech/medical, genetics

A multi-gene expression signature in tumors is associated with aggressive disease and poor patient outcomes, and it has the potential to become a genetic cancer biomarker.

The human cell’s primary source of energy, the mitochondria plays an important role in the metabolism of cancer cells. In a study recently published in PLOS ONE, researchers from throughout the world, including Dario C. Altieri, M.D., president and chief executive officer, director of the Ellen and Ronald Caplan Cancer Center, and Robert and Penny Fox Distinguished Professor at The Wistar Institute, have identified a particular gene signature indicative of mitochondrial reprogramming in tumors that is associated with a poor patient outcome.
