Medical Xpress / Life after work: Why social connections matter
Social networks may help protect cognitive functioning in later life, particularly among older adults who are no longer working, according to a new IIASA-led study. Drawing on data from 27 European countries, the researchers ...
Phys.org / Neutron-rich nuclei yield beta-decay clues that could refine heavy-element origin models
How are heavy elements formed in the universe? Extremely neutron-rich atomic nuclei and their beta-decay rates play an important role in this process. Until now, it has been very difficult to determine these rates experimentally. ...
Phys.org / Chemists unlock first total synthesis of rare plant alkaloid tied to anticancer activity
Plants are undeniably one of nature's most promising sources of new medicines, with monoterpenoid indole alkaloids (MIAs) being a great example. Some intricate compounds are built from multiple-linked chemical units that ...
Phys.org / Examining doctoral students' attitudes toward AI chatbots and ChatGPT use in higher education
Researchers from the University of Phoenix College of Doctoral Studies have published research examining graduate students' attitudes toward artificial intelligence (AI) chatbots and their reported use of ChatGPT in higher ...
Phys.org / Bacteria can learn and form memories without a brain
Researchers at Carnegie Mellon University have shown that bacteria can learn from past experiences, store memories across generations and adapt their behavior to changing environments, all without a brain or nervous system. ...
Phys.org / Photoexcitation flips 2D moiré devices from metals to insulators in ultrafast test
Quantum materials, materials with properties that are governed by the laws of quantum mechanics describing many-body interactions, have proved promising for the development of various advanced technologies. Many of these ...
Phys.org / Hagfish fossils reveal stepwise eye simplification before near-total vision loss
Many animals, including humans, rely on their eyes to detect changes in their surroundings. The eyes of vertebrates, animals with a backbone or a similar supporting structure, contain a transparent structure (i.e., the lens) ...
Phys.org / Antibiotics drive resistance in waterways—even after they break down
Antibiotics continue to drive resistance in bacteria, even after they are broken down in wastewater treatment plants and discharged into rivers and seas, new research published on World Oceans Day has shown for the first ...
Phys.org / Distinctive language reveals likely conspiracy-community users across 500 million Reddit comments
Users who participate in online communities linked to conspiracy theories show distinctive linguistic characteristics even when discussing apparently neutral topics, such as films, music, cooking or science, and even before ...
Phys.org / SpaceX's hold over orbit matches East India Company's grip on maritime trade
Elon Musk's SpaceX holds sway over the emerging space economy in a way that has more in common with notorious colonial-era trading companies than the competitive markets of today's textbooks, according to a new study.
Phys.org / Brazilian breadbasket's aquifers are falling, and new satellite maps show where water stress is growing
A collaboration of scientists from NASA and Brazilian research institutions has produced a detailed picture of groundwater change across Brazil. The images reveal significant declines in some of the aquifers that are critical ...
Tech Xplore / Organic transistor unites memory, signal processing and light emission below 3.5 V
Seoul National University researchers have developed an ultra-low-voltage electrochemical organic light-emitting transistor that can simultaneously perform signal processing, memory and light emission within a single semiconductor ...
