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.

Milwaukee plans to build a new, unnamed project featuring up to 55 floors constructed largely from engineered mass timber materials. If completed, it would be the world's tallest timber skyscraper, surpassing the current record-holder, the 25-story Ascent tower. The project will include residential units, office space, retail space, hotel rooms, and parking spaces.

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.

New research reveals that cobras and their relatives, thought to have originated in Africa, actually evolved in Asia. 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." According to calculations, this could trap existing heat and scatter sunlight across the Martian surface, boosting its natural greenhouse effect. While this approach may seem unconventional, experts believe it could be up to 5,000 times more efficient than previous terraforming methods.
