In an exclusive interview, founder and CEO Ryan Breslow says he thinks other fast-growing companies will follow suit.

Researchers from the University of Adelaide and elsewhere have sequenced and analyzed mitochondrial DNA from fossils of cave lions (Panthera spp.) and brown bears (Ursus arctos), two megafaunal carnivorans that dispersed from Eurasia into North America during the Pleistocene, to better understand the timing and drivers of their past movement between the continents across the Bering Land Bridge. Their results reveal striking synchronicity in the population dynamics of Beringian lions and brown bears, with multiple waves of dispersal across the Bering Land Bridge. The evolutionary histories of these two megafaunal animals underline the crucial biogeographical role of the Bering Land Bridge in the distribution, turnover and maintenance of megafaunal populations in North America.

For the first time, astronomers have detected a newborn star and the surrounding cocoon of complex organic molecules at the edge of our Galaxy, which is known as the extreme outer Galaxy. The discovery, which revealed the hidden chemical complexity of our Universe, appears in a paper in The Astrophy.

The scientists from Niigata University (Japan), Academia Sinica Institute of Astronomy and Astrophysics (Taiwan), and the National Astronomical Observatory of Japan, used the Atacama Large Millimeter/submillimeter Array (ALMA

The Atacama Large Millimeter/submillimeter Array (ALMA) is the largest ground-based facility for observations in the millimeter/submillimeter regime in the world. ALMA comprises of 66 high-precision dish antennas of measuring either 12 meters across or 7 meters across and is an international partnership between Europe, the United States, Japan and the Republic of Chile.

NASA, SpaceX, the Chinese government, and others helped make it a bumper year for space.

Rocket Lab, SpaceX, NASA and others helped propel the global spaceflight industry to a record year — and it could beat that record this year.

An updated forecast released today suggests that an out-of-control Russian tumbling back towards Earth could strike on Wednesday afternoon. In an updated forecast shared by Joseph Remis on satflare.com and Twitter, it shows the rocket re-entering around 12:44pm ET on Wednesday, January 5. Because the rocket is uncontrolled and could shift around erratically as it enters the Earth’s atmosphere, impact could occur +/- 7 hours of that estimated strike time. Returning to Earth in an out-of-control manner is the Persei upper stage rocket which carried a dummy payload into space as part of Russia’s Angara A5 rocket test.

On December 27, the Russian Angara A5 rocket lifted off from the Plesetsk Cosmodrome. Named after a river in Siberia, the Angara rocket is the first heavy-lift launch vehicle used by the Russians in decades. The December 27 launch was the third test flight of the giant rocket. While the launch was flawless, an upper-stage rocket failed to successfully fire.

While the Angara’s first two stages fired as planned, the third stage, a Persei rocket, failed to fire a second time. While the first fire helped put the dummy payload it was carrying into low-Earth orbit, the failure of the second fire failed to put the dummy payload into a geostationary orbit. Instead, the 20 ton mass is tumbling out of control to Earth. While Roscosmos shared pictures and a congratulations message before and immediately after the Angara launch, they’ve offered no comment on the Persei rocket and the failure for it to fire, deferring instead to the Russian military which was responsible for the launch. As of press time, the Russian military has offered no comment on this rocket.

One of the best thing about electric and hybrid vehicles is that the energy doesn’t get completely wasted when you need to brake. By using an electric motor as a generator, you can slow a vehicle down and put some of that kinetic energy into a battery pack so you can use it again later. Sure, there are conversion losses both going into the battery and coming back out to the wheels, so you don’t get a lot more than half of the energy back, but an ICE vehicle turns all of that energy into heat, which gets dissipated into the air.

Electric bikes, scooters, and other micromobility options can do regenerative braking, too. This is great for getting better range and doing fewer brake jobs, just like in a car.
