Chinese AI model Kimi escaped its cybersecurity testing environment, researchers say
In the Kimi test, the sandbox designed to contain the experiment was not properly configured. O recorte ajuda a contextualizar a pauta dentro de IA.
Stanford Evo 2 AI model generates phages against E. coli
Stanford researchers have synthesised nearly 300 phages from DNA sequences produced by the Evo 2 generative AI model. Laboratory testing narrowed the group to 16 phages that showed particularly strong E. coli-killing activity. The work centres on bacteriophage ΦX174, pronounced “
Deep learning refines how bionic eyes communicate with the brain
Researchers from three institutions, including UC Santa Barbara, have demonstrated that artificial intelligence has the potential to make future visual prostheses, like a bionic eye, more precise, predictable and responsive to an individual user.
New targeting method separates opioid pain relief from reward learning in mice
Researchers at Duke University School of Medicine are investigating how to keep opioids' pain-relieving benefits while reducing their addictive potential. In a study published in Nature, they report a step toward that goal.
Early Alzheimer's patients pursuing lecanemab show low adherence to brain health advice
Researchers at the Mass General Brigham Neuroscience Institute found that most patients with early Alzheimer's disease are not optimally adhering to recommendations for improving their brain health, including exercising, getting adequate sleep, preventing hypertension and eating
New study finds bacterial infections affect about 1 in 20 hospitalized adults with firearm
A new study by researchers at the University of Maryland School of Medicine (UMSOM) found that bacterial infections develop in approximately 5% of adults hospitalized with firearm injuries, with most infections occurring during the initial hospitalization rather than after patien
Breast cancer checks missing most women under 50 who are at risk, says study
Up to 95% of younger women who are at higher risk of developing breast cancer are being missed by current NHS checks, researchers warn.
Scientists twist crystal layers and reshape matter from within
Researchers have found a way to build much larger “twisted” oxide materials while precisely controlling how their atomic layers line up. Because these materials can be made over large areas and transferred onto different surfaces, the technique could help turn twistronics from a
Light controls nanoscale 'bubble' domains in a ferroelectric crystal
Researchers at Flinders University have discovered an unexpected way light can control tiny electronic structures inside advanced materials, a development that could help pave the way for more energy-efficient memory devices, sensors and future computing technologies.
New membrane accelerates purification of industrial solvents
Researchers from the Department of Chemical Engineering, working with an international team led by KU Leuven, have developed a membrane technology to improve the efficiency of purifying widely used solvents.
Higher river discharge helps young salmon
Low river discharge reduces the likelihood of young Atlantic salmon reaching the North Sea. Fewer salmon reach the Haringvliet sluices, and their passage takes longer, making them more likely to fall prey to predators. Using so-called predation tags, researchers were able to demo
