Recent research published in PNAS Nexus This suggests that while artificial intelligence chatbots can match or exceed human creativity when it comes to individual tasks, they produce very similar responses when compared to each other. This provides evidence that widespread reliance on artificial intelligence in creative work can lead to a loss of unique ideas. Scientists Emily Wenger and Yod N. Kennett designed this study to understand how large-scale language models affect the diversity of human thought. Large-scale language models are the technology behind popular AI chatbots that predict and generate text based on user prompts. Large-scale language models are…
Engineers at Northwestern University have created printed artificial neurons that can go beyond imitation and interact directly with real brain cells. These flexible, low-cost devices generate electrical signals that closely resemble those produced by living neurons and can activate biological brain tissue. In experiments using mouse brain slices, artificial neurons were able to trigger responses in real neurons. This result demonstrates a new level of compatibility between electronic devices and living neural systems. Towards brain interfaces and energy-efficient AI This advance brings researchers closer to electronics that can connect directly to the nervous system. Potential applications include neuroprosthetics such as…
The appointment of a new leader for the U.S. Centers for Disease Control and Prevention with scientific credentials and no public ties to the anti-vaccination movement has brought a sigh of relief to the public health world. One CDC official, speaking on condition of anonymity Friday, said the “overall mood is cautious but hopeful” among staff. STAT Plus: Inside the change of CDC director: Kennedy demands acceptance of new vaccine policy. Susan Monares refused Still, even those praising the choice of retired Maj. Gen. Erica Schwartz for the U.S. Public Health Service Commissioned Forces are worried about whether she will…
New research from Green Drill, a project co-led with the University at Buffalo to recover rocks and sediment buried beneath the Greenland Ice Sheet, reveals that the Prudhoe Dome ice sheet completely disappeared about 7,000 years ago. This is much more recent than scientists previously believed. The survey results are natural earth scienceindicating that this high region in the northwestern part of the ice sheet is highly sensitive to even modest warming. The melting occurred during the Holocene, a relatively stable climatic period that began 11,000 years ago and continues today. “This is an era known for climate stability, when…
Recent research published in journals Social cognitive and affective neuroscience This provides evidence that when listening to live music, brain waves synchronize more strongly with the rhythm of the music than when listening to recordings. This enhanced brain-music synchronization tends to predict how much joy and enthusiasm a person will experience during a performance. The findings provide a biological explanation for why attending a concert is so much more moving than playing a song on a cell phone or computer. Even though high-quality audio streaming has made pristine recordings available on demand, participation in live music remains widespread around the…
A bill in the Illinois General Assembly would require certified pesticide users (those authorized by the Illinois Department of Agriculture to use restricted pesticides, such as paraquat or fumigating pesticides) to provide written or email notice at least 24 hours in advance of their application if they choose to pick up their application at a school, child care facility, or park within 1,500 feet of the application. According to House Bill 1596, the notification must include the intended location and date and time range of use, the common name of each product and the type of pesticide used, the name…
A new study reveals that ground vibrations were significantly reduced in cities across the United States and Canada during the total solar eclipse on April 8, 2024. The researchers presented their findings at the 2026 SSA Annual Meeting, showing that urban areas within the “path of totality” were temporarily seismically quiet as the moon completely blocked the sun. Benjamin Fernando, a seismologist and planetary scientist at Johns Hopkins University, happened to be in the Ohio city during the event. “And then all of a sudden I realized that everything was really quiet,” he said. “So we were interested in seeing…
A new study has found that some of the ocean’s most powerful predators are getting hotter than expected, and the consequences could be severe. These animals already require large amounts of energy to survive, but now they are facing increasing challenges due to rising ocean temperatures and decreasing food availability. Scientists describe this as a “double jeopardy” where both environmental stress and biological demands work against you. The study, led by scientists from Trinity College Dublin in collaboration with the University of Pretoria’s (UP) School of Veterinary Medicine, showed that certain warm-bodied fish, such as tuna, and some sharks, such…
Eating more fruits, vegetables, and whole grains is widely recommended to improve health and reduce the risk of cancer and other diseases. But new findings from the University of Southern California Norris Comprehensive Cancer Center, part of the Keck School of Medicine at the University of Southern California, suggest there may be unexpected risks for certain groups. A study presented at the annual meeting of the American Association for Cancer Research shows that nonsmoking Americans under age 50 who eat healthier diets may be at higher risk of developing lung cancer. “Our study shows that young nonsmokers who consume more…
A new study led by researchers at University College London has shown that combining quantum computing and artificial intelligence can significantly improve predictions of complex physical systems over long periods of time. Hybrid approaches perform better than leading models that rely solely on traditional computers. The result is scientific progresscould enhance the simulation of the behavior of liquids and gases, known as fluid dynamics. These types of models are essential in areas such as climate science, transportation, medicine, and energy production. Why quantum computing makes a difference The increased accuracy appears to come from the way quantum computers process information.…
