An engine idea that can accelerate to 99 percent of the speed of light, all without the need for propellant. That may sound like something out of a science fiction movie, but it’s not. This is exactly what one of NASA engineers is developing, and it promises to break the law of physics.

How will these engines be developed? If it is going to work without propellant, then what will be its fuel? And most importantly, will a human be able to travel in a vehicle with such an engine as its thruster? Well, we will find out in just a second.

Electronic measurements can determine entropy in quantum dots and single molecules — a measurement that has been historically difficult to perform.

As science fiction would have you believe, you can’t really go to “another dimension.” Dimensions are more about how we see the world. But some things point to not just one, but two dimensions of time, according to one expert. If it were true, the theory could fix the biggest problem in physics, which is that quantum mechanics and general relativity don’t agree with each other.

Itzhak Bars from the University of Southern California in Los Angeles says that’s the case. Up, down, left, right, forward, back, and space-time are the normal three dimensions. In Bars’s theory, time is not a straight line. Instead, it is a curved 2D plane that is woven into all of these dimensions and more.

Dr. Bars has been working on “two-time physics” for more than ten years. All of this started when he started to wonder what time has to do with gravity and other forces. Even though the idea of more dimensions sounds strange, more and more physicists are thinking about it because it could help create the “theory of everything” or “unified theory of physics” that everyone wants. This would put all of the basic forces of the universe into a single, simple math equation.

Plastic foam like Styrofoam is a ubiquitous, harmful and nearly immortal single-use material that is long overdue for a good, green replacement — and Cruz Foam is here to supply it. The startup creates a durable yet backyard-compostable packing foam out of shrimp shells produced (and discarded) by the seafood industry. It recently extended its seed round to accommodate the interests of Leonardo DiCaprio and Ashton Kutcher, and is scaling up to meet the demands of its first major customer, Whirlpool.

I met Cruz Foam co-founder John Felts during the memorable Accelerator at Sea hosted by the Sustainable Ocean Alliance. His pitch made perfect sense: create a biodegradable alternative to expanded polystyrene (EPS) foam using a material provided in abundance by nature.

As New York prepares for the imminent launch of legal adult-use marijuana sales, the governor has signed a bill aimed at expanding the state’s hemp market by promoting collaborative partnerships to identify more opportunities to utilize the crop and its derivatives for packaging, construction and other purposes.

Bill sponsor Sen. Michelle Hinchey (D) announced on Tuesday that Gov. Kathy Hochul (D) approved her legislation late last month. It would amend a section of New York’s agriculture law that deals with hemp economic development, mandating that the agriculture commissioner consult with additional partners on ways to incorporate hemp products into business operations throughout the state.

Nearly three years into the pandemic, travel has returned but hotel staff have not. Unable to find workers, hotel owners and managers are having to adapt to what they believe is the new normal.

Wait, how many stars were at this party? It’s likely there were up to five – but only two appear now! A research team recently began digging into Webb’s highly detailed images of the Southern Ring Nebula to reconstruct the scene. It’s possible more than one star interacted with the dimmer of the two central stars, which appears red in this image, before it created this jaw-dropping planetary nebula. The first star that “danced” with the party’s host created a light show, sending out jets of material in opposite directions. Before retiring, it gave the dim star a cloak of dust. Now much smaller, the same dancer might have merged with the dying star – or is now hidden in its glare.

A third partygoer may have gotten close to the central star multiple times. That star stirred up the jets ejected by the first companion, which helped create the wavy shapes we see today at the edges of the gas and dust. Not to be left out, a fourth star with an orbit projected to be much wider, also contributed to the celebration. It circled the scene, further stirring up the gas and dust, and generating the enormous system of rings seen outside the nebula. The fifth star is the best known – it’s the bright white-blue star visible in the images that continues to orbit predictably and calmly.

The final showstopping finding is an accurate measurement of the mass that the central star had before it ejected its layers of gas and dust. Researchers estimate the star was about three times the mass of the Sun before it created this planetary nebula – and about 60 percent of the mass of the Sun after. It’s still early days – this is some of the first published research about some of Webb’s first images to be released, so plenty more details are sure to come.
