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 steal gun owners’ data from firearm auction website
Posted by Genevieve Klien in category: futurism
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.

Putting Carbon Dioxide to Good — Scientists Use Electrochemistry To Convert Carbon to Useful Molecules
Posted by Paul Battista in categories: chemistry, innovation
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 Food We May Eat At The End Of The 21st Century
Posted by 21st Century Tech Blog in categories: ethics, food
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.

Dying Montgomery High student’s final words to a friend: ‘Everything will be ok’
Posted by Eric Klien in categories: computing, government
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.

US-Japan team hails H2-boron plasma fusion breakthrough
Posted by Quinn Sena in categories: nuclear energy, physics
An innovative nuclear fusion technology that uses no radioactive materials and is calculated capable of “powering the planet for more than 100,000 years”, has been successfully piloted by a US-Japanese team of researchers.
California-based TAE Technologies, working with Japan’s National Institute for Fusion Science (NIFS), have completed first tests of a hydrogen-boron fuel cycle in magnetically-confined plasma, which could generate cleaner, lower cost energy that that produced by the more common deuterium-tritium (D-T) fusion process.
“This experiment offers us a wealth of data to work with and shows that hydrogen-boron has a place in utility-scale fusion power. We know we can solve the physics challenge at hand and deliver a transformational new form of carbon-free energy to the world that relies on this non-radioactive, abundant fuel,” said Michl Binderbauer, CEO of TAE Technologies.

The future of touch: Researchers uncover physical limitation in haptic holography
Posted by Genevieve Klien in categories: augmented reality, virtual reality
Haptic holography promises to bring virtual reality to life, but a new study reveals a surprising physical obstacle that will need to be overcome.
A research team at UC Santa Barbara has discovered a new phenomenon that underlies emerging holographic haptic displays, and could lead to the creation of more compelling virtual reality experiences. The team’s findings are published in the journal Science Advances.
Holographic haptic displays use phased arrays of ultrasound emitters to focus ultrasound in the air, allowing users to touch, feel and manipulate three-dimensional virtual objects in mid-air using their bare hands, without the need for a physical device or interface. While these displays hold great promise for use in various application areas, including augmented reality, virtual reality and telepresence, the tactile sensations they currently provide are diffuse and faint, feeling like a “breeze” or “puff of air.”
