Animator Hashem Al-Ghaili has shown off a concept for the nuclear-powered sky hotel on YouTuber.

A video rendering shows off the vessel, called the Sky Cruise, which is described as a "futuristic hotel above the clouds. Animated by Al-Ghaili, the video features designs by Tony Holmsten of an aircraft capable of hosting 5,000 guests while remaining in the air for over a year continuously, with small aircraft able to ferry passengers and supplies to it by landing on its decks.

"Thanks to nuclear energy, the hotel never runs out of fuel and can remain suspended in the air for several years without ever touching the ground," claimed the designers.

A study on cocaine titled "Muscarinic Acetylcholine M2 Receptors Regulate Lateral Habenula Neuron Activity and Control Cocaine Seeking Behavior" has been published in The Journal of Neuroscience.

Researchers from the National Institute on Drug Abuse (NIDA), a component of the National Institutes of Health (NIH), discovered that blocking particular acetylcholine receptors in the brains of rats made it more difficult for them to resist seeking cocaine. In the experiment, rats were trained to recognize when cocaine was available based on a light being turned on or off and to self-administer cocaine by pressing a lever, resulting in the injection of the drug.

The researchers blocked the receptors in the lateral habenula (LHb), a brain area responsible for balancing reward processing and inhibition. The LHb is particularly interesting because it interfaces with various brain regions associated with reasoning, reward systems, and higher-order thought processes - factors associated with substance abuse disorders.

A study on influenza vaccination and Alzheimer's disease titled "Risk of Alzheimer's Disease Following Influenza Vaccination: A Claims-Based Cohort Study Using Propensity Score Matching" has been published in the Journal of Alzheimer's Disease.

Researchers from the University of Texas Health Science Center at Houston (UTHealth Houston) have found that people administered at least one dose of influenza vaccine are 40% less likely to develop Alzheimer's disease over the next four years compared to non-vaccinated peers. Their study involved a "large nationwide sample of U.S. adults aged 65 and older," with and without prior flu vaccination.

"We found that flu vaccination in older adults reduces the risk of developing Alzheimer's disease for several years. The strength of this protective effect increased with the number of years that a person received an annual flu vaccine - in other words, the rate of developing Alzheimer's was lowest among those who consistently received the flu vaccine every year. Future research should assess whether flu vaccination is also associated with the rate of symptom progression in patients who already have Alzheimer's dementia," said first author Avram S. Bukhbinder, MD, a recent alumnus of McGovern Medical School at UTHealth Houston.

A study on the experiment titled "Rapid Radiolytic Degradation of Amino Acids in the Martian Shallow Subsurface: Implications for the Search for Extinct Life" has been published in the journal Astrobiology.

A recent NASA laboratory experiment indicates that potential signs of ancient life on Mars are more likely found about 6.6 feet (~2 meters) below the Martian surface. Researchers determined that ionizing radiation from space could quickly destroy small molecules like amino acids, erasing signs of life from the surface. Though amino acids can be created by non-biological chemistry or by life, their discovery on Mars would be strong evidence for terrestrial life.

"Our results suggest that amino acids are destroyed by cosmic rays in the Martian surface rocks and regolith at much faster rates than previously thought. Current Mars rover missions drill down to about two inches (around five centimeters). At those depths, it would take only 20 million years to destroy amino acids completely. The addition of perchlorates and water increases the rate of amino acid destruction even further," said Alexander Pavlov of NASA's Goddard Space Flight Center in Greenbelt, Maryland.

The National Oceanic and Atmospheric Administration has just replaced two outdated supercomputers with new supercomputers that will bring massive upgrades to weather forecasting.

The National Oceanic and Atmospheric Administration (NOAA) announced back in 2020 that it would be replacing some of its older, now-outdated supercomputers that are used to run weather forecasts and predict patterns. NOAA has now replaced the older models, which were Cry and IBM supercomputers located in Reston, Virginia, Florida, and Orlando - with two Hewlett Packard Enterprise (HPE) Cray supercomputers.

These two supercomputers come with 2,560 AMD Epyc Rome 64-core 7742 server CPUs that collectively provide 327,680 cores that are capable of operating up to 12.1 petaflops. This new setup is approximately three times faster than what NOAA was previously using, and with the new upgraded power, the agency believes it will be able to provide more accurate and detailed weather forecasts to the public. Notably, the two new NOAA supercomputer systems are called Dogwood and Cactus, and rank as the 49th and 50th fastest supercomputers in the world.

Elon Musk has finally reached a milestone number of Twitter followers, and that number has arrived on Musk's birthday.

Tesla and SpaceX CEO Elon Musk has reached 100 million Twitter followers on June 28, 2022, the day of his 51st birthday. A massive uptick in followers occurred when Musk entered into a deal to purchase Twitter, the world's second largest social media platform, for $54.20 a share, or $44 billion. However, the deal is somewhat thrown up in the air as Musk has said the acquisition won't go ahead until Twitter can prove that less than 5% of its userbase are bot/spam accounts.

Earlier this month Twitter executives said that they would comply with Musk's request to provide him with userdata, and said that Musk will receive the full "firehose" of Twitter data that consists of a staggering 500 million tweets posted each day. Since Musk announced the deal to purchase Twitter the company's stock has dropped considerably, with its current price sitting at approximately $38 a share.

SpaceX is moving forward with its preparations for Starship's first orbital test flight, following the environmental report recently conducted by the Federal Aviation Administration (FAA).

The FAA recently evaluated the environmental impact of SpaceX conducting orbital launches of its Starship launch vehicle in its Texas test site, and according to the regulators' recently released report, Elon Musk's vehicle and launch site were found to have "Finding Of No Significant Impact (FONSI)". However, the FAA did give SpaceX many requests to prevent any future environmental impact and also put a cap on the number of launches SpaceX can conduct per year - five orbital launches and five suborbital launches.

With that review by the FAA now out of the way, Elon Musk and SpaceX can move forward with getting everything in order to perform Starship's first orbital test flight, which, when achieved, will be a monumental milestone for the company and another big step on the road to getting a consistent human presence on the Mars and the moon. On June 23 SpaceX was spotted rolling out Super Heavy Booster 7 to the orbital launch site, and according to reports from NASASpaceFlight, the booster sported 33 Raptor 2 engines.

Astronomers identified Comet C/2017 K2 back in 2017, and now the extremely old comet is making its way into our inner solar system.

Researchers believe that Comet C/2017, or Comet K2, originally came from the Oort Cloud, and when it was originally found, it was approximately 1.5 billion miles away from the Sun between Saturn and Uranus. When Comet K2 was first discovered, astronomers believed it was 99 miles wide, but follow-up observations from the Hubble Space Telescope brought that number down to the agreed 11-mile-wide diameter.

It should be noted that while the diameter estimate was originally incorrect, the size of Comet K2 is still very large - being as wide as two Mount Everest's stacked on top of each other. Spaceweather.com writes that most comet nuclei are approximately 0.62 - 1.86 miles in diameter. Comet K2 harbors its own mysteries as most of the larger comets do, with researchers being perplexed at how the comet remains "active", which is a term researchers use to label comets that are producing a glow and the iconic tail.
