Checkerspot raises $13M Series A to produce biotech-enabled performance materials

Posted by in categories: bioengineering, biotech/medical, chemistry

Checkerspot, a biotech startup using microalgae to produce performance materials, announced today that it has closed its Series A financing for $13 million. The round was led by Builders VC, and included Breakout Ventures, Viking Global Investors, KdT Ventures, Plug and Play Ventures, Sahsen Ventures, and Godfrey Capital, among others.

Checkerspot combines bioengineering, chemistry, and materials science to go from microalgae to next-generation performance materials.

“This is a pretty significant milestone for us,” said Checkerspot CEO Charles Dimmler. He said the funding would support the company’s continued infrastructure development, as well as ongoing commercial activities with Beyond Surface Technologies and DIC that focus on novel triglycerides and polyols. He also said it would help complete the development of a direct-to-consumer product later this year.

Quantum gold rush: the private funding pouring into quantum start-ups

Posted by in categories: computing, quantum physics

A Nature analysis explores the investors betting on quantum technology. The science is immature and a multi-purpose quantum computer doesn’t yet exist. But that isn’t stopping investors pouring cash into quantum start-ups.

Making the rules in space: When does careful become crushing?

Posted by in categories: engineering, government, space travel

Other approaches to space involve moving some or all the engineering activities out of government into the private sector, in the hopes that the private sector will be able to produce otherwise unavailable efficiencies. This sounds good in practice, but we must recognize that shifting some management responsibilities does not alleviate the government responsibility to regulate and look out after the public good.

But imprudent regulation impairs private sector efforts, simply because they may have a harder time getting relief from government rules than, let’s say, the DoD might. Unnecessarily stringent rules, requirements, and regulations discourage success. The precautionary principle has its appeal, but when the underlying activity itself is relatively new and uncertain, precautionary restrictions quickly turn into outright prohibition. Any arbitrary prohibition limits the diversity of our national spaceflight portfolio.

It may seem that this or that actor might benefit from favoritism, permissive oversight, or other unfair advantages. But while everybody trying to do something new in space benefits from distinct benefits and advantages, they also face unique obstacles and difficulties.

DNA Nanomachines Are Opening Medicine to the World of Physics

Posted by in categories: biotech/medical, chemistry, nanotechnology, robotics/AI

When I imagine the inner workings of a robot, I think hard, cold mechanics running on physics: shafts, wheels, gears. Human bodies, in contrast, are more of a contained molecular soup operating on the principles of biochemistry.

Yet similar to robots, our cells are also attuned to mechanical forces—just at a much smaller scale. Tiny pushes and pulls, for example, can urge stem cells to continue dividing, or nudge them into maturity to replace broken tissues. Chemistry isn’t king when it comes to governing our bodies; physical forces are similarly powerful. The problem is how to tap into them.

In a new perspectives article in Science, Dr. Khalid Salaita and graduate student Aaron Blanchard from Emory University in Atlanta point to DNA as the solution. The team painted a futuristic picture of DNA mechanotechnology, in which we use DNA machines to control our biology. Rather than a toxic chemotherapy drip, for example, a cancer patient may one day be injected with DNA nanodevices that help their immune cells better grab onto—and snuff out—cancerous ones.

When — or if — NASA finds life on Mars, the world may not be ready for the discovery, the agency chief says

Posted by in category: alien life

NASA’s next mission to Mars will be its most advanced yet. But if scientists discover there was once life — or there is life — on the Red Planet, will the public be able to handle such an extraterrestrial concept?

NASA chief scientist Jim Green doesn’t think so.

“It will be revolutionary,” Green told the Telegraph. “It will start a whole new line of thinking. I don’t think we’re prepared for the results. We’re not.”

Atom-by-atom experiments at the edge of the periodic table

Posted by in categories: chemistry, particle physics

Investigating the heaviest elements known is rewriting our knowledge of chemistry and may even mean the end of the periodic table itself, writes Kit Chapman.

In 2018, Peter Schwerdtfeger published a paper that turned chemistry on its head. According to calculations he and his colleagues performed, oganesson – element 118, the heaviest known – was not a noble gas as you would expect from its position in the periodic table, but a highly reactive solid. Even stranger, it didn’t seem to have electron shells.1

‘Well, that statement is oversimplified,’ says Schwerdtfeger, a theoretical chemist at Massey University in New Zealand. ‘You can still build up the electron densities from orbitals describing individual shells. What happens is that for oganesson the shell structure is barely visible, approaching an electron gas.’

Squid-inspired robots might have environmental, propulsion applications

Posted by in categories: military, physics, robotics/AI

Inspired by the unique and efficient swimming strategy of cephalopods, scientists developed an aquatic robot that mimics their form of propulsion.

These , squidlike robots are made of , which make them hard to detect—an advantage that has potential military reconnaissance and scientific applications—while maintaining a low environmental footprint.

Physicists Xiaobo Bi and Qiang Zhu used to illustrate the physical mechanisms and fluid mechanics of a squid’s swimming method, which uses intermittent bursts through pulsed jet propulsion. By using this form of locomotion, the new can achieve impressive speeds, just like its animal inspiration. Bi and Zhu discuss their work in this week’s Physics of Fluids.
