Was SHA-256 cracked? Don’t buy into retraction!

Posted by in categories: bitcoin, cryptocurrencies, encryption, government, hacking, internet, mathematics, military, privacy, security, software

SHA-256 is a one way hashing algorithm. Cracking it would have tectonic implications for consumers, business and all aspects of government including the military.

It’s not the purpose of this post to explain encryption, AES or SHA-256, but here is a brief description of SHA-256. Normally, I place reference links in-line or at the end of a post. But let’s get this out of the way up front:

One day after Treadwell Stanton DuPont claimed that a secret project cracked SHA-256 more than one year ago, they back-tracked. Rescinding the original claim, they announced that an equipment flaw caused them to incorrectly conclude that they had algorithmically cracked SHA-256.

All sectors can still sleep quietly tonight,” said CEO Mike Wallace. “Preliminary results in this cryptanalytic research led us to believe we were successful, but this flaw finally proved otherwise.

Design Devices to Help Astronauts Eat: Lunch in Outer Space!

Posted by in categories: engineering, food, space

Summary In this open-ended design/build project, students learn about the unique challenges astronauts face while eating in outer space. They explore different food choices and food packaging, learning about the seven different forms of food that are available to astronauts. Students learn about the steps of the engineering design process, and then, as if they are NASA engineering teams, they design and build original model devices to help astronauts eat in a microgravity environment—their own creative devices for food storage and meal preparation. A guiding design worksheet is provided in English and Spanish.

Artificial Intelligence Confronts a ‘Reproducibility’ Crisis

Posted by in category: robotics/AI

Machine-learning systems are black boxes even to the researchers that build them. That makes it hard for others to assess the results.

Death is Inevitable but Aging is Not

Posted by in categories: biotech/medical, food, genetics, life extension

Age is not the definitive factor it’s made out to be when it comes to our health. We can use our age as a baseline for tracking our health and longevity, but it isn’t stagnant. For example, certain types of testing can help us compare our biological age to our calendar age in order to tinker with our wellness routine and achieve the milestones we’re after. With the right steps, we can slow down and even sometimes reverse the aging process.

When it comes to our biological age, or the measure of how well our body is actually functioning for whatever life stage we are in, there are many things that impact it. Diet, lifestyle patterns like exercise and sleep, and stress are all involved in forming our biological age, along with many other factors like blood sugar, inflammation, and genetics. This week on The Doctor’s Farmacy, I’m joined by Dr. David Sinclair to explore the topic of longevity and anti-aging and how he reduced his own internal age by more than 20 years. Dr. Sinclair is a professor in the Department of Genetics and co-director of the Paul F. Glenn Center for the Biology of Aging at Harvard Medical School, where he and his colleagues study longevity, aging, and how to slow its effects.

Nanoparticles used to transport anti-cancer agent to cells

Posted by in categories: biotech/medical, engineering, nanotechnology

Scientists from the University of Cambridge have developed a platform that uses nanoparticles known as metal-organic frameworks to deliver a promising anti-cancer agent to cells.

Research led by Dr. David Fairen-Jimenez, from the Cambridge Department of Chemical Engineering and Biotechnology, indicates (MOFs) could present a viable platform for delivering a potent anti-cancer agent, known as siRNA, to .

Small interfering ribonucleic acid (siRNA), has the potential to inhibit overexpressed cancer-causing genes, and has become an increasing focus for scientists on the hunt for new cancer treatments.

Research suggests new approach for treating inflammation

Posted by in categories: biotech/medical, genetics

Medications that mitigate inflammation caused by a variety of diseases including rheumatic arthritis may also compromise a person’s immune system, but a new approach points to a possible solution to this problem.

Researchers have discovered a mechanism that might alleviate inflammation by suppressing the of a type of white blood cells called neutrophils. The cells migrate within tissues in order to kill pathogens but may also cause excessive inflammation, resulting in tissue injury and other adverse effects.

The scientists identified a genetic molecule called miR-199, a type of “microRNA,” which reduces the migration of neutrophils, therefore potentially relieving inflammation without compromising the immune system.

The Guardian GT exoskeleton is a crazy strong robot

Posted by in categories: cyborgs, nuclear energy, robotics/AI

I get to try the Guardian GT big-arm robot, which is like a real-life Power Loader from Aliens. It’s controlled by a human and has incredible precision, but it’s also incredibly strong. Made by Sarcos Robotics, the GT can be used in situations that are too dangerous for humans to enter, like decommissioning nuclear power plants.
