Phys.org reports that NASA's Hubble Space Telescope has officially passed the 1 billion second mark over the 31 years it has been operating. During that time, the famous telescope, named after astronomer Edwin Hubble, has been serviced by astronauts five times and is the only space telescope that is designed to be serviced by astronauts. The servicing missions include astronauts replacing core components that have malfunctioned over prolonged use.

For context of this "use", Hubble has made more than 1.5 million scientific observations over its operational time, and that number is still growing today. During its operation time, researchers have used Hubble to unlock deeper understandings of the universe and how it works, with its instruments leading to breakthroughs in astrophysics such as a more precise estimation of the expansion of the universe, black holes, and more.

The rocket part that has crashed back down to Earth is the upper stage of the Russian Angara A5 rocket tested on December 2021. The rocket was uncrewed and was also carrying a satellite. NBC reported that its engine malfunctioned shortly after the rocket was launched, causing it to remain stuck in low-Earth orbit before eventually falling back down to the surface.

On Wednesday, the four tons of material plummeted back down to Earth, entering Earth's atmosphere somewhere over the Pacific Ocean and landing in an unknown area. Jonathan McDowell, a Harvard astronomer, warned that four tons of material entering the atmosphere could pose a risk as not all of the material will burn up, some pieces may make it to the surface. However, McDowell noted that the majority of the planet is covered in ocean and that it's more likely that it would hit the sea than land, which it seems to have done.

This video is humanity's last look at the James Webb Space Telescope

Jak Connor | Fri, Jan 7 2022 1:04 AM CST

NASA's next-generation space telescope dubbed the James Webb Space Telescope departed from Earth on Christmas Day, and the below video is probably the last time humanity will ever see the observatory ever again.

NASA has taken to its blog to explain why the James Webb Space Telescope isn't equipped with a series of cameras that can relay footage of the unfolding process back to headquarters for engineers and public viewing. The space agency explains that there are a plethora of problems that arise if Webb was equipped with cameras, the first being that the space telescope is very shiny, so any cameras directed at Webb's sun-facing side would be subject to extreme glare.

Cameras equipped to the side of the observatory that's in the shade would require a light source. NASA notes that infrared cameras could have solved the lighting problem, but would present "harnessing disadvantages". The space agency writes that engineers considered adding cameras and proceeded to draw up mock designs with cameras equipped, but ultimately decided that "that deployment surveillance cameras would not add significant information of value for engineering teams commanding the spacecraft from the ground."

The two-millimeter wide, self-powered aqueous robots, dubbed 'liquibots,' can deliver chemicals while partially submerged in a solution. They can potentially be used for drug delivery in pharmaceutical applications or as part of an automated chemical synthesis framework.

Previous liquibots have been made but could only carry out an autonomous task once, only able to continue indefinitely with electricity. These new liquibots can harvest the energy they need to continue working from the chemicals in their environment.

"We have broken a barrier in designing a liquid robotic system that can operate autonomously by using chemistry to control an object's buoyancy," said senior author Tom Russell, a professor of polymer science and engineering from the University of Massachusetts Amherst.

The addition will begin nationwide on Monday, January 10th, 2022, but won't hang around forever. Yum! Brands, KFC's parent company, previously worked with Beyond Meat to sell out a plant-based chicken product at a KFC restaurant in Atlanta in under five hours in August 2019.

"This is really about where the customer is going; they want to eat more plant-based proteins. It's January, so it's a time of New Year's resolutions and wanting to do something different in your diet," said Kevin Hochman, U.S. president of KFC

It's not the first instance of psychedelics being studied for potential medical applications.

New clinical trials using DMT are underway for depression treatment 01 | TweakTown.com

N,N-Dimethyltryptamine, or DMT, is a hallucinogenic compound that has recently joined some other psychedelic compounds, including LSD, MDMA, ketamine, and psilocybin mushrooms, in a new wave of research into their use for potential therapies. The various compounds have shown promise for treatment of mental illnesses such as post-traumatic stress disorder (PTSD) and depression, particularly in traditionally treatment-resistant varieties.

"There's a significant unmet medical need. Of course, there are treatments for major depressive disorder, like SSRIs, but there's a huge underserved population because these treatments don't work for everybody and they have side effects too," said Dr. Carol Routledge, the chief medical and scientific officer at Canadian pharmaceuticals company Small Pharma.

The team of researchers from the Ben-Gurion University of the Negev built a fish-operated vehicle (FOV) to test if the goldfish were able to translate their navigational skills into a new environment, similar to how rats have done in previous research that involved them using little cars to get themselves to a destination.

They taught the goldfish to navigate a room by swimming inside its water tank, mounted above the FOV. A downward-facing camera, computer, and LIDAR system overhead tracked the fish and its orientation as it moved within the tank. The computer then used this to inform the movement of the FOV below.

NASA confirms this ocean absorbs 500 million tons of carbon every year

Jak Connor | Thu, Jan 6 2022 3:03 AM CST

Researchers have penned a new study that details the Southern Ocean that is located around Antarctica, putting previous studies into question.

The new study published in the journal Science found that the waters in the Southern Ocean are absorbing around 0.53 petagrams or 530 million metric tons of carbon than they were releasing each year. Additionally, the researchers found that there was a stronger summertime uptake of carbon and less wintertime outgassing.

Previously researchers weren't sure about the exact impacts of the Southern Ocean and how much the waters were absorbing atmospheric carbon dioxide (CO2). The recently published study has now confirmed for researchers that the Southern Ocean is a substantial carbon sink and will assist in reducing overall CO2 levels caused by humans.
