A cybersecurity technique that shuffles network addresses like a blackjack dealer shuffles playing cards could effectively befuddle hackers gambling for control of a military jet, commercial airliner or spacecraft, according to new research. However, the research also shows these defenses must be designed to counter increasingly sophisticated algorithms used to break them.

Many aircraft, spacecraft and weapons systems have an onboard computer network known as military standard 1,553, commonly referred to as MIL-STD-1553, or even just 1553. The network is a tried-and-true protocol for letting systems like radar, flight controls and the heads-up display talk to each other.

Securing these networks against a cyberattack is a national security imperative, said Chris Jenkins, a Sandia cybersecurity scientist. If a hacker were to take over 1,553 midflight, he said, the pilot could lose control of critical aircraft systems, and the impact could be devastating.

An exploding white dwarf and a massive galaxy cluster are the keys.

Making an embryo is much like making a Lego castle: In the same way that a castle needs turrets and gargoyles and a moat, you need two legs and two eyes and a heart.

Except unlike the Lego Camelot, you don’t come with a picture on the box of what you’re meant to look like, much less an instruction manual—and you’re not going to be the one to assemble the structure. Instead, you’ll sit back and wait for the Lego pieces to organize themselves. Our cells, our little Lego pieces, assembled themselves. What’s even more astonishing is that when they get it right, all those cells get it right in broadly the same ways: We all managed to come out with the characteristic shape and proportions appropriate to our species (we can all spot a regulation-issue chicken, frog, mouse, or human shape).

Hackers breached a website that allows people to buy and sell guns, exposing the identities of its users, TechCrunch has learned.

The breach exposed reams of sensitive personal data for more than 550,000 users, including customers’ full names, home addresses, email addresses, plaintext passwords and telephone numbers. Also, the stolen data allegedly makes it possible to link a particular person with the sale or purchase of a specific weapon.

A joint effort in chemistry has resulted in an innovative method for utilizing carbon dioxide in a positive – even beneficial – manner: through electrosynthesis, it is integrated into a series of organic molecules that play a crucial role in the development of pharmaceuticals.

During the process, the team made an innovative discovery. By altering the type of electrochemical reactor used, they were able to generate two distinct products, both of which are useful in medicinal chemistry.

The team’s paper was recently published in the journal Nature. The paper’s co-lead authors are postdoctoral researchers Peng Yu and Wen Zhang, and Guo-Quan Sun of Sichuan University in China.

What will people be eating at the end of the 21st century?

The foods we eat are determined by cultural roots, geography, and moral and ethical concerns. Omnivore, vegetarian, and vegan are choices.

Just in case people are curious how accurate the news is, the following article says “Nvidia, AMD, and TSMC will still bear the bulk of the risk for establishing manufacturing within the United States.” The reality is that neither Nvidia or AMD makes chips. In that list, only TSMC is a chip manufacturer.

The U.S. Secretary of Commerce reminds investors that the federal government supports a sweeping shift in how and where chips are made.
