Lifeboat Foundation

Imagine you’re a fisherman living by a lake with a rowboat. Every day, you row out on the calm waters and life is good. But then your family grows, and you need more fish, so you go to the nearby river. Then, you realize you go farther and faster on the river. You can’t take your little rowboat out there—it’s not built for those currents. So, you learn everything you can about how rivers work and build a better boat. Life is good again…until you realize you need to go farther still, out on the ocean. But ocean rules are nothing like river rules. Now you have to learn how ocean currents work, and then design something even more advanced that can handle that new space.

Communication frequencies are just like those water currents. And the boats are just like the tools we build to communicate. The challenge is twofold: learning enough about the nature of each frequency and then engineering novel devices that will work within them. In a recent paper published in Proceedings of the IEEE, the flagship publication of the largest engineering society in the world, one USC Viterbi School of Engineering researcher has done just that for the next generation of cellular networks—6G.

Andy Molisch, professor of electrical and computer engineering at USC Viterbi and the holder of the Solomon Golomb—Andrew and Erna Viterbi Chair, together with colleagues from Lund University in Sweden, New Zealand Telecom, and King’s College London, explained that we have more options for communications at 6G frequency than previously thought. Think of it as something like early explorers suddenly discovering the gulf stream.

The scientists found that there are some key differences between different FRBs, some of which were one-off bursts and some of which rapidly repeated, according to CNN. That lead them to believe that the different categories are given off by fundamentally different sources of cosmic phenomena, they said in research presented Wednesday at a meeting of the American Astronomical Society. The next steps, of course, are to figure out what those sources actually are.

Thanks to just a year’s worth of observations that greatly expanded the known number of FRBs, the scientists now have much more to work with as they try to figure out what’s causing them. It also highlights the fact that FRBs, once thought to be rare occurrences, appear to be common phenomena in the grand scheme of things.

“That’s kind of the beautiful thing about this field — FRBs are really hard to see, but they’re not uncommon,” MIT physicist and CHIME member Kiyoshi Masui said in a press release. “If your eyes could see radio flashes the way you can see camera flashes, you would see them all the time if you just looked up.”

A Penn State scientist studying crystal structures has developed a new mathematical formula that may solve a decades-old problem in understanding spacetime, the fabric of the universe proposed in Einstein’s theories of relativity.

“Relativity tells us space and time can mix to form a single entity called spacetime, which is four-dimensional: three space-axes and one time-axis,” said Venkatraman Gopalan, professor of materials science and engineering and physics at Penn State. “However, something about the time-axis sticks out like sore thumb.”

For calculations to work within relativity, scientists must insert a negative sign on time values that they do not have to place on space values. Physicists have learned to work with the negative values, but it means that spacetime cannot be dealt with using traditional Euclidean geometry and instead must be viewed with the more complex hyperbolic geometry.

Because it was, 62 years ago, the first fully reusable space vehicle, two stages, both reusable. The same concept of Virgin Galactic SpaceShipTwo.

OmniFoods is far from the only player breaking into the space. Last year, Nestlé announced its entrance into the category, rolling out a vegan tuna product in Switzerland. Impossible has also previously announced it was working on an alternative fish product.

OmniFoods, the Hong Kong startup best known for its fake pork product “OmniPork,” is jumping on what it sees as the next phenomenon: plant-based seafood.

In an announcement first shared with CNN Business, the company said Tuesday it is launching a new line of products that include alternatives to fish fillets, fish burgers and cuts of tuna.

The explosion contained elements of three different types of solar eruptions: Bubble-like coronal mass ejections, beam-like jets, and partial eruptions that collapse onto themselves. Those eruptions all happen independently of one another, making this hybrid the first of its kind to ever be spotted, according to CNET. NASA is referring to the explosion as a sort of “solar Rosetta Stone,” comparing it to the ancient slab that helped researchers decode Egyptian hieroglyphs, because picking apart the three different eruptions could help researchers finally understand the root causes for each and how they differ.

The 2016 explosion was too big to be a jet but too narrow to be a coronal mass ejection, according to a NASA press release. And when it finished, a partial eruption emerged from the same place just to bubble up and fall back onto itself. Seeing all three forms of eruption emerge in the same place and within the same hour suggested to NASA that all three are caused by the same mechanisms, according to the research, which was presented at Monday’s American Astronomical Society meeting and has been accepted for publication in Astrophysical Journal Letters.

“This event is a missing link where we can see all of these aspects of different types of eruptions in one neat little package,” NASA solar scientist and lead study author Emily Mason said in the release. “It drives home the point that these eruptions are caused by the same mechanism, just at different scales.”

“We’re trying to ice skate to where the puck is going,” Ellis said, adding that Relativity wants to be similarly disruptive to SpaceX, but in its own way. “What we keep hearing from customers is that they don’t want just a single launch company that is, frankly, the only quickly moving, disruptive provider.”

Powered by seven main engines, the Terran R vehicle will initially launch from Cape Canaveral Space Force Station in Florida. Relativity has set a goal to launch in 2024, and Ellis said the company has signed a binding contract for multiple launches with an “anchor customer” he declined to name. Relativity has not publicly released a price for a launch.

Launched in 1998, the ISS serves as the largest hub for scientific research and collaboration in orbit. The U.S., Russia, Canada and Japan alongside a dozen countries participating in the European Space Agency work in support of the ISS.

Circumstantial evidence could point to a mind-blowing solution to an antimatter mystery—or to the need for better space-based particle physics experiments.
