However, only a small positive overall effect ( = 0.201) favoring MML over traditional instruction was detected, implying the actual difference between the overall group means was present but trivial.
Additionally, a sensitivity analysis later revealed differing results from the primary analysis, indicating the meta-analytic findings need to be interpreted with caution (Aromataris & Munn, 2020). Nevertheless, these meta-analytic findings suggest that educational leaders and policymakers can make better informed decisions to address the high failure and low retention rates in college algebra. Furthermore, those evaluating CAI for learner use can utilize the findings with the aim of improving student learning and facilitation using technological tools.Link to Original Source

Sleep may not just be rest for the mind—it may be essential maintenance for the body's power supply. A new study by University of Oxford researchers, published in Nature, reveals that the pressure to sleep arises from a build-up of electrical stress in the tiny energy generators inside brain cells.

A gene called SDR42E1 has been identified as a key player in how our bodies absorb and process vitamin D. Researchers found that disabling this gene in colorectal cancer cells not only crippled their survival but also disrupted thousands of other genes tied to cancer and metabolism. This opens the door to highly targeted cancer therapies—by either cutting off vitamin D supply to tumors or enhancing the gene’s activity to boost health.

Around a Sun-like star just 1,300 light-years away, a family of planets has been seen in its earliest moments of conception.
Astronomers analyzed the infrared flow of dust and detritus left over from the formation of a baby star called HOPS-315, finding tiny concentrations of hot minerals that will eventually form planetesimals – the 'seeds' around which new planets will grow.

A team of scientists has developed a powerful new way to detect subtle magnetic signals in common metals like copper, gold, and aluminum—using nothing more than light and a clever technique. Their research, recently published in Nature Communications, could pave the way for advances in everything from smartphones to quantum computing.

Monitoring changes in water temperature and pressure at the seafloor can improve understanding of ocean circulation, climate, and natural hazards such as tsunamis. In recent years, scientists have begun gathering submarine measurements via an existing infrastructure network that spans millions of kilometers around the planet: the undersea fiber-optic telecommunications cables that provide us with amenities like Internet and phone service.

Two colossal black holes—among the most massive ever seen—collided in deep space, creating gravitational waves that rippled across the cosmos and shook the foundations of astrophysical theory. Detected by the LIGO-Virgo-KAGRA observatories, this record-breaking merger has stunned scientists not only because of its size, but also due to the black holes’ extreme spins, challenging our current understanding of how such behemoths form.

Most crystals, from the humble table salt to the toughest diamonds, obey the same rule: their atoms are arranged in a lattice structure that repeats in three-dimensional space. Quasicrystals break this rule – the pattern in which their atoms are arranged does not repeat.
When the concept first emerged in the scientific world in 1984, this was thought to be impossible: crystals were either ordered or disordered, with no in-between. Then they were actually found, both created in laboratory settings and in the wild – deep inside meteorites, forged by thermodynamic shock from events like a hypervelocity impact.

A century later, technologies based on quantum mechanics are everywhere.
Devices like mobile phones depend on advanced applications of the theory of quantum electrodynamics, which describes the interactions between matter and electromagnetic radiation at the level of individual atoms.

To summarize, the FBI pays some shady companies to scrape data, the data is scanned for keywords (yep, just like CARNIVORE). Links and content are then fed into Facebook, organized by topic based on the keywords. Some rudimentary analysis is performed (sentiment analysis at least, but as friendly as Microsoft is with the feds, and as LLMs have gotten popular, the influence of machines has probably expanded) and perused by agents, using some FBI internal interface.

Studies have also shown that AI chatbots exhibit more systematic hateful patterns. For instance, one study found that various chatbots such as Google’s Bard and OpenAI’s ChatGPT perpetuated “debunked, racist ideas” about Black patients. Responding to the study, Google claimed they are working to reduce bias.
