Fraud rings using fake "bot" students have infiltrated America's community colleges, stealing over $11 million from California's system alone in 2024. The nationwide scheme, which began in 2021, targets open-admission institutions where scammers enroll fictitious students in online courses to collect financial aid disbursements. "We didn't used to have to decide if our students were human," said Eric Maag, who has taught at Southwestern College for 21 years. Faculty now spend hours vetting suspicious enrollees and analyzing AI-generated assignments. At Southwestern in Chula Vista, professor Elizabeth Smith discovered 89 of her 104 enrolled students were fraudulent. The California Community College system estimates 25% of all applicants statewide are bots. Community college administrators describe fighting an evolving technological battle against increasingly sophisticated fraud tactics. The fraud crisis has particularly impacted asynchronous online courses, crowding real students out of classes and fundamentally altering faculty roles.

Meta has disabled Apple Intelligence features across its iOS applications, including Facebook, WhatsApp, and Threads, according to Brazilian tech blog Sorcererhat Tech. The block affects Writing Tools, which enable text creation and editing via Apple's AI, as well as Genmoji generation. Users cannot access these features via the standard text field interface in Meta apps. Instagram Stories have also lost previously available keyboard stickers and Memoji functionality. While Meta hasn't explained the decision, it likely aims to drive users toward Meta AI, its own artificial intelligence service that offers similar text and image generation capabilities. The move follows failed negotiations between Apple and Meta regarding Llama integration into Apple Intelligence, which reportedly collapsed over privacy disagreements. The companies also maintain ongoing disputes regarding App Store policies.

A global gambling syndicate led by secretive Tasmanian gambler Zeljko Ranogajec and London bookmaker Bernard Marantelli successfully executed an unprecedented operation to claim a $57.8 million Texas lottery jackpot in 2023. The group, operating through a limited partnership called Rook TX, purchased 99.3% of all possible number combinations, printing over 25 million tickets across four makeshift workshops in Texas. Using dozens of official lottery terminals and working nearly around the clock for three days, the team systematically printed hundreds of tickets per second. Texas officials have since launched investigations, with Lt. Governor Dan Patrick calling it "the biggest theft from the people of Texas in the history of Texas." The Texas Rangers are now investigating the operation. Through legal representation, the syndicate maintains they "followed all applicable laws, rules and regulations" throughout the process.

Astronomers have detected what may be the strongest evidence yet of extraterrestrial life on K2-18b, a massive exoplanet orbiting a star 120 light-years from Earth. The research team, led by Cambridge astronomer Nikku Madhusudhan, published their findings today in the Astrophysical Journal Letters. Using the James Webb Space Telescope, researchers found significant concentrations of dimethyl sulfide and dimethyl disulfide in K2-18b's atmosphere. On Earth, these sulfur compounds are exclusively produced by living organisms, particularly marine algae. "It is in no one's interest to claim prematurely that we have detected life," said Madhusudhan, though he described the findings as "a revolutionary moment" and "the first time humanity has seen potential biosignatures on a habitable planet." The team detected the signals during two separate observations, with the second showing an even stronger signature. Their analysis suggests K2-18b may be a "Hycean" planet -- covered with warm oceans and wrapped in a hydrogen-rich atmosphere -- with concentrations of dimethyl sulfide thousands of times higher than Earth levels. Other scientists remain cautious. Christopher Glein of the Southwest Research Institute suggested K2-18b could instead be "a massive hunk of rock with a magma ocean and a thick, scorching hydrogen atmosphere." Further observations with Webb and future NASA telescopes will be necessary to confirm whether K2-18b is truly habitable or inhabited, though planned budget cuts may impact follow-up research.

In a recent interview with Wired, Nobel laureate Venkatraman Ramakrishnan discusses his book Why We Die, in which he argues that death is not genetically programmed but rather a consequence of evolution favoring reproduction over longevity. Here are some of the most thought-provoking excerpts: WIRED: Professor Ramakrishnan, the crucial question in your book is why we die. But exactly what is death? Venki Ramakrishnan: By death, we mean the irreversible loss of the ability to function as a coherent individual. It is the result of the failure of a critical system or apparatus, for example, heart, brain, lung, or kidney failure. In this sense there is an apparent paradox: When our organism, as a whole, is alive, millions of cells within us are constantly dying, and we do not even realize it. On the other hand, at the time of death, most of the cells in our bodies are still alive, and entire organs are still functioning and can be donated to people in need of transplantation. But at that point the body has lost the ability to function as a whole. In this sense, it is therefore important to distinguish between cell death and death of the individual. Speaking of death and aging, you say in your most recent book that you "wanted to offer an objective look at our current understanding of the two phenomena." What was the biggest surprise or most deeply held belief that you had to reconsider while writing and researching this work? There have been several surprises, actually. One is that death, contrary to what one might think, is not programmed by our genes. Evolution does not care how long we live, but merely selects the ability to pass on our genes, a process known as "fitness" in evolutionary biology. Thus, the traits that are selected are those that help us survive childhood and reproduce. And it is these traits, later in life, that cause aging and decline. Another curious finding was the fact that aging is not simply due to wear and tear on cells. Wear and tear happens constantly in all living things, yet different species have very different lifespans. Instead, lifespan is the result of a balance between the expenditure of resources needed to keep the organism functioning and repairing it and those needed to make it grow, mature, and keep it healthy until it reproduces and nurtures offspring. Do you think there is an aspect of the biology of aging that is still deeply misunderstood by the general public? Certainly the indefinite extension of life. Although in principle there are no laws or constraints that prevent us from living much longer than we do currently, great longevity or "eternal youth" are still far off, and very significant obstacles to increasing our maximum life expectancy remain. We must also beware of the pseudoscience -- and business -- around the concepts of "anti-aging" or the "reversal of aging." These are often baseless concepts, unsupported by hard evidence, even though they may use language that sounds scientific. Unfortunately, we are all afraid of growing old and dying, so we are very sensitive to any claim that promises to help us avoid it. [...] What do you think are the social and ethical implications of our desire to live longer? Ever since we became aware of our mortality, we have desired to defeat aging and death. However, our individual desires may conflict with what is best for society. A society in which fertility rates are very low and lifespans are very high will be a stagnant society, with very slow generational turnover, and probably much less dynamic and creative. The Nobel Prize-winning South American novelist Mario Vargas Llosa, who recently passed away, expressed it best: "Old age on the one hand terrifies us, but when we feel anxious, it is important to remember how terrible it would be to live forever. If eternity were guaranteed, all the incentives and illusions of life would vanish. This thought can help us live old age in a better way."

Microsoft has acknowledged that Classic Outlook can mysteriously transform into a system resource hog, causing CPU usage spikes between 30-50% and significantly increasing power consumption on both Windows 10 and 11 systems. Users first reported the issue in November 2024, but Microsoft only confirmed the problem this week, offering little resolution beyond stating that "the Outlook Team is investigating this issue." The company's sole workaround involves forcing a switch to the Semi-Annual Channel update through registry edits -- an approach many enterprise environments will likely avoid. Microsoft hasn't announced a definitive end date for Classic Outlook, but the company continues pushing users toward its New Outlook client despite its incomplete feature set.

After more than a decade of development, Harvard's insect-sized flying robot, RoboBee, has successfully learned to land using dragonfly-inspired legs and improved flight controls. The researchers see RoboBee as a potential substitute for endangered bees, assisting in the pollination of plants. From a report: RoboBee is a micro flying robot that Harvard has been developing since 2013. As the name suggests, it is the size of a bee, capable of flying like a bee and hovering in mid-air. Its wings are 3 cm long and it weighs only 0.08 g. The weight was reduced by using light piezoelectric elements instead of motors. Piezoelectric elements change shape when an electric current flows through them. The researchers were able to make RoboBee flap its wings 120 times per second by turning the current on and off, which is similar to actual insects. While RoboBee exhibited flight capabilities comparable to those of a bee, the real problem was landing. Being too light and having short wings, it could not withstand the air turbulence generated during landing. It is easy to understand if you think about the strong winds generated when a helicopter approaches the ground. Christian Chan, a graduate student at Harvard who participated in the research, said, "Until now, it was a matter of shutting off the robot while it attempted to land and praying for a proper touchdown." To ensure RoboBee's safe landing, it was important to dissipate energy just before touchdown. Hyun Nak-Seung, a professor at Purdue University who participated in the development of RoboBee, explained, "For any flying object, the success of landing depends on minimizing speed just before impact and rapidly dissipating energy afterward. Even for tiny flapping like RoboBee's, the ground effect cannot be ignored, and after landing, the risk of bouncing or rolling makes the situation more complex." The findings have been published in the journal Science Robotics.

Researchers at the University of Tokyo have created what they believe is the largest single piece of lab-grown meat to date: a chicken nugget-sized chunk measuring 7 centimeters long, 4 centimeters wide, and 2.25 centimeters thick, weighing 11 grams. The breakthrough, reported today in Trends in Biotechnology, uses an artificial circulatory system to overcome a fundamental limitation in cultured meat production. The team, led by biohybrid system engineer Shoji Takeuchi, grew cells around a network of semipermeable hollow fibers -- similar to those used in water filters and dialysis machines -- that deliver nutrients and oxygen throughout the tissue. Unlike most commercial approaches that produce tiny meat fragments later assembled with binders or scaffolds, this method creates a single coherent piece with more natural structure and texture. This is the first working model using tubes to grow muscle tissue into a thick slab, according to Mark Post, chief science officer at Mosa Meat, who created the world's first lab-grown hamburger in 2013. Significant hurdles remain before commercialization. The hollow fibers aren't edible and must be manually removed. Researchers are exploring automating this process or creating edible alternatives using cellulose.

Discord has begun testing age verification via facial scans or ID uploads for users in the UK and Australia seeking access to sensitive content. "The chat app's new process has been described as an 'experiment,' and comes in response to laws passed in those countries that place guardrails on youth access to online platforms," reports Gizmodo. From the report: Users may be asked to verify their age when encountering content that has been flagged by Discord's systems as being sensitive in nature, or when they change their settings to enable access to sensitive content. The app will ask users to scan their face through a computer or smartphone webcam; alternatively, they can scan a driver's license or other form of ID. "We're currently running tests in select regions to age-gate access to certain spaces or user settings," a spokesperson for Discord said in a statement. "The information shared to power the age verification method is only used for the one-time age verification process and is not stored by Discord or our vendor. For Face Scan, the solution our vendor uses operates on-device, which means there is no collection of any biometric information when you scan your face. For ID verification, the scan of your ID is deleted upon verification."
