A transiting gas giant called WASP-62b has a cloud-and haze-free atmosphere, according to new research.
For example, the first and only other known exoplanet with a clear atmosphere, WASP-96b, was discovered in 2018.

I say squish immediately!!
Scientists think they have discovered the undersea lair of a giant predatory worm that lived on the ocean floor some 20 million years ago and would pounce on unsuspecting marine creatures.
Paleontologists from National Taiwan University believe the 6.5-foot-long burrow was once home to a worm-like predator that would surface from the seabed to ambush sea creatures and drag them, alive, into its lair.

Tesla recently shared some footage of its next-generation 4680 battery cells being produced. The video, which seems to be taken from the electric car maker’s pilot Roadrunner line, suggests that Tesla’s 4680 battery manufacturing system may very well be Elon Musk’s elusive “Alien Dreadnought” concept coming to life.
During the lead up to the Model 3’s initial ramp, Elon Musk envisioned a vehicle production system that was so automated, it would look extraterrestrial in nature. Dubbed as the “Alien Dreadnought,” this concept ultimately fell short of its targets, and Tesla eventually adopted a production system for the Model 3 that combined both human and automated machines. Since then, Tesla has taken steps towards increasing the automation of its vehicle production system, as evidenced by parts like the Model Y’s rigid wiring, which are optimized for installation by robots.
Tesla’s video of its 4680 battery production line suggests that the company’s level of automation has reached levels that have never been seen before. As noted by TSLA bull @truth_tesla on Twitter, the footage shared by Tesla in its recruitment video showed a battery production line that is incredibly automated. This could be seen immediately in Tesla’s main battery production line, which, unlike traditional battery manufacturing facilities, is largely absent of human workers.
Things we already know: The world is growing uncomfortably warm due to humanity’s insistence on burning fossil fuels. Elon Musk is currently the wealthiest human on the planet. Yet for being among the wealthiest people on the planet, Musk’s philanthropic track record over the years has been paltry compared to the likes of Jeff Bezos. So, yeah, it did come as a bit of a surprise on Thursday when the Tesla CEO took to Twitter to announce that he plans to donate $100 million as a prize towards a winning carbon capture system.
Am donating $100M towards a prize for best carbon capture technology— Elon Musk (@elonmusk) January 212021
Details on Musk’s upcoming carbon capture competition have not been released but are expected to arrive “next week.” This is not the first time that a company has sought the public’s help with carbon capture technology, which seeks to pull this element from the atmosphere and squirrel it away to help slow the rate of human-induced climate change. In 2018, X-Prize held a similar competition and awarded five finalist teams a share of its $20 million grand prize. But with a $100 million purse on the line, Musk’s competition will not only offer five times the funding as X-Prize, it’ll also constitute his single-largest philanthropic investment to date (10 times the amount of his second-largest donations so far). Of course, this is far from the first effort to collect and convert atmospheric CO2 into consumer products.
The DMC DeLorean has been out of production for almost 40 years, but now we’ve learned that the iconic vehicle might be coming back as an electric car.
The DMC DeLorean was the only vehicle produced by John DeLorean’s DeLorean Motor Company (DMC).
It became famous for being featured in the ‘Back to the Future’ series of movies, but it is also a well-known vehicle in the industry for a few reasons.
New technology from Stanford scientists finds long-hidden quakes, and possible clues about how earthquakes evolve.
Tiny movements in Earth’s outermost layer may provide a Rosetta Stone for deciphering the physics and warning signs of big quakes. New algorithms that work a little like human vision are now detecting these long-hidden microquakes in the growing mountain of seismic data.
Measures of Earth’s vibrations zigged and zagged across Mostafa Mousavi’s screen one morning in Memphis, Tenn. As part of his PhD studies in geophysics, he sat scanning earthquake signals recorded the night before, verifying that decades-old algorithms had detected true earthquakes rather than tremors generated by ordinary things like crashing waves, passing trucks or stomping football fans.
A team of scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) inGermany, Givskud Zoo–Zootopia in Denmark and the University of Milan in Italy succeeded in producing the very first African lionin-vitroembryos after the vitrification of immature oocytes. For this specific method of cryopreservation, oocytes are collected directly after an animal is castrated or deceased and immediately frozen at-196°C in liquid nitrogen. This technique allows the storage of oocytes of valuable animals for an unlimited time, so that they can be used to produce offspring with the help of assisted reproduction techniques. The aim is to further improve and apply these methods to save highly endangered species such as the Asiatic lion from extinction. The current research on African lions as a model species is an important step in this direction. The results are reported in the scientific journal Cryobiology.
Lion oocytes are presumed to be very sensitive to chilling due to their high lipid content, resulting in poor revival following slow cooling. Vitrification can circumvent this problem, as the cells are frozen at ultra-fast speeds in solutions with a very high concentration of cryoprotective agents. This method prevents the formation of ice crystals in the cells, which could destroy them, and enables them to remain intact for an unlimited time to allow their use later on.
For the present research, the scientists collected oocytes from four African lionesses from Givskud Zoo—Zootopia after the animals had been euthanised for the purpose of population management. Half of the oocytes (60) were vitrified instantly. After six days of storage in liquid nitrogen, the vitrified oocytes were thawed and subjected toin-vitromaturation in an incubator at 39°C for a total of 32–34 hours. The other half (59) were used as control group and directly subjected toin-vitromaturation without a step of vitrification. Mature oocytes of both groups were then fertilized with frozen-thawed sperm from African lion males. “We could demonstrate a high proportion of surviving and matured oocytes in the group of vitrified oocytes. Almost 50% of them had matured, a proportion similar to that in the control group,” says Jennifer Zahmel, scientist at the Department of Reproduction Biology at the Leibniz-IZW.
Circa 2018 o.o!
We are not living in the first universe. There were other universes, in other eons, before ours, a group of physicists has said. Like ours, these universes were full of black holes. And we can detect traces of those long-dead black holes in the cosmic microwave background (CMB) — the radioactive remnant of our universe’s violent birth.
At least, that’s the somewhat eccentric view of the group of theorists, including the prominent Oxford University mathematical physicist Roger Penrose (also an important Stephen Hawking collaborator). Penrose and his acolytes argue for a modified version of the Big Bang.

Spiral galaxies are one of the most commonly known types of galaxy. Most people think of them as large round disks, and know that our Milky Way is counted among their number. What most people don’t realize is that many spiral galaxies have a type of warping effect that, when you look at them edge on, can make it seem like they are forming a wave. Now scientists, led by Xinlun Chen at the University of Virginia, have studied millions of stars in the Milky Way and begun to develop a picture of a “wave” passing through our own galaxy.
Since humans are not currently able to view the Milky Way in an edge-on orientation, they must resort to more brute force methods to develop models about the what, if any, wave our galaxy has. Luckily, scientists now have the tools to do so, in the form of the Sloan Digital Sky Survey and ESA’s Gaia satellite.
The method the team used was to try to identify and track the motions of as many stars as possible. To do this, they used the Apache Point Observatory Galactic Evolution Experiment (APOGEE) spectrograph, which is part of the SDSS. This preliminary data allowed them to look at both the chemical compositions as well as the motions of hundreds of thousands of stars. While this motion data was helpful in starting to form the picture of the Milky Way’s wave, it was not sufficient to complete it.
