NASA's NEOWISE telescope, a pioneering asteroid hunter, is set to meet its demise in late 2024 after a remarkable 15-year mission. Launched in 2009 as WISE, the spacecraft exceeded expectations, detecting over 200 previously unknown near-Earth objects and providing valuable data on thousands more. As the sun's solar maximum approaches, NEOWISE will safely burn up in the atmosphere, marking the end of an era in planetary defense.

Google's DeepMind AI has been trained to play table tennis, and it can beat human players - but only at a moderate level. According to a recent study, the AI-controlled robot arm defeated beginners and intermediate players, but was outplayed by advanced players. The researchers used a customized version of DeepMind's learning algorithm to train the robot, which learned specific skills like creating top spin and using backhand targeting. While the AI showed promise in some areas, it struggled with high balls and found backhand shots more challenging than forehand ones.

A recent study suggests that a single mutation in the COVID-19 variant JN.1 may have enabled it to evade antibodies and spread globally, despite many people being vaccinated and having previous infections. Researchers found that 66 out of 899 antibodies prevented infection by BA.2.86, while only 23 prevented JN.1 infection. The study suggests that a longer amino acid in JN.1's spike protein may have weakened or blocked neutralizing antibodies from interacting with the virus.

New study finds that double mastectomies do not increase cancer survival rates for women with unilateral breast cancer. The research, published in JAMA Oncology, analyzed data from over 660,000 women and found no significant difference in overall death rates between those who underwent a double mastectomy and those who had only the affected breast or tumor removed.

Astronomers have observed a supermassive black hole devouring a giant star in the biggest Tidal Disruption Event (TDE) ever seen. This phenomenon, where a star is torn apart by a black hole's gravitational force, produces some of the brightest events in the sky. The discovery provides clues to understanding mysteriously bright cosmic objects in the centers of active galaxies.

Researchers have made a groundbreaking discovery in understanding why some people with ALS (amyotrophic lateral sclerosis) recover from the disease. A rare gene variant, IGFBP7, has been found to be 12 times more likely to occur in patients who recover from ALS compared to those whose condition continues to progress.

Recent research by OpenAI warns about the potential risks of humans forming close relationships with AI chatbots. The study found that users may anthropomorphize these models, leading to a false sense of trust and potentially influencing social norms. This could result in individuals becoming more isolated and relying on AI for companionship.
The report also highlights concerns about AI-powered conversations influencing real-life interactions, making people awkward or even rude when communicating with humans. Additionally, the study notes that AI chatbots can be used to normalize abusive behavior, as some users have already demonstrated with previous models.
However, the research also suggests that these advanced AI models could provide benefits for lonely individuals and those with learning differences.

A innovative solution to keep buildings cooler without using energy has been proposed by researchers. A zigzag design on walls can maximize heat radiation into space while minimizing absorption from the ground, potentially reducing greenhouse gas emissions. According to Qilong Cheng at Columbia University, this approach could reduce energy consumption for cooling and help combat global warming.

Researchers have been puzzled by a mysterious type of antibiotic resistance called heteroresistance, where a small fraction of bacteria can evade antibiotics. Microbiologist Karin Hjort is on a mission to uncover the mechanisms behind this phenomenon. Heteroresistant bacteria can rapidly switch between resistant and susceptible states, making it difficult to detect using routine clinical tests.

Did you know that there are two main types of bacteria? Gram-positive and gram-negative bacteria differ in their cell wall composition, which affects how they respond to antibiotics. The names "gram-positive" and "gram-negative" date back to 1884, when Hans Christian Gram developed a staining procedure. Researchers have found that both classes of bacteria share strategies for resisting antibiotics, but gram-negative bacteria have an edge due to their double membranes.

New research reveals that bacteria can develop antibiotic resistance in a surprisingly short time frame, from instantaneous to several days. This rapid evolution is due to the ability of some bacteria to divide rapidly, passing on genetic changes that provide resistance. While resistance mechanisms take varying amounts of time to emerge, scientists are working to overcome this challenge through the use of combination therapies and a better understanding of antibiotic penetration.

Breaking, also known as breakdancing, has made its Olympic debut! Researchers have found similarities between brain patterns of ballet dancers, figure skaters, and slackliners with those of people experiencing vestibular impairments. The study discovered lower-than-average density in white matter tracts, overlapping in both groups' brains. This might be due to the need to suppress or reinterpret vestibular input for balance. Additionally, elite athletes like breakdancers develop complex movement sequences, which become encoded in efficient brain activity. This could explain why trained athletes don't need to consciously think about their movements.

Get ready for a celestial show! Three powerful solar explosions, or coronal mass ejections (CMEs), are expected to hit Earth's magnetic field this weekend, potentially bringing stunning auroras as far south as New York and Idaho. This coincides with the peak of the Perseid meteor shower, making it an ideal time for stargazers. The CMEs are expected to trigger a mild geomagnetic storm, which could create colorful auroras visible in the northern parts of most states along the U.S.-Canada border.

A stunning new image from the James Webb Space Telescope (JWST) captures the breathtaking beauty of spiral galaxy Messier 106. Located a mere 23 million light-years away, this galaxy is relatively close to our own Milky Way and is one of the brightest in the sky. The image showcases the galaxy's swirling arms, which are illuminated by powerful radiation as gas spirals towards its supermassive black hole. This active galactic nucleus is unlike that found at the center of the Milky Way, which only occasionally pulls in wisps of gas.

Researchers warn that AI models trained on AI-generated data could spiral into unintelligible nonsense, making them less useful and filling the internet with incomprehensible babble. A study published in Nature found that as AI systems rely more heavily on their own output for training, they may create self-damaging feedback loops, leading to model collapse. This issue can be addressed by taking care when designing synthetic data and ensuring models are built to improve over time.

The Florida Python Challenge aims to control invasive Burmese python population in the Everglades. From August 8-18, snake hunters will track down and humanely kill as many pythons as possible. The challenge is part of efforts to remove over 11,000 pythons from the ecosystem since 2017. Prizes up to $25,000 are available for participants. While some hunters see the challenge as a way to engage with the public, others like Amy Siewe, a former state contractor, raise concerns about drawing large crowds that may scare off pythons.

Scientists analyzed genetic data from 65 species of snakes and found that the earliest ancestors of these snakes emerged in Asia between 28.94 and 45.92 million years ago. The study suggests that these snakes spread across the world through multiple waves, with some migrating from Asia to Africa and others dispersing to Europe, Australasia, and the Americas.

Scientists have proposed an innovative method to warm up Mars, potentially by 50 degrees Fahrenheit. The plan involves seeding the planet's atmosphere with reflective metallic nanorod particles, commonly known as "glitter."
