a) Schematic: Metal foil inserted for internal heating and fast heat transfer to electrodes and electrolyte. Self-heating activated by switching off the connection between activation terminal and negative terminal. b) Evolution of cell voltage and temperature during activation at Vact = 0.4 V (inset) and subsequent 1C discharge at −20 °C. Battery temperature increases from −20 °C to 0 °C...
The MoodCapture app could allow people with major depressive disorder to maintain control of their condition. Credit: Depositphotos Measuring the severity of major depression can be difficult for individuals experiencing it. However, in the near future, a smartphone app utilizing artificial intelligence to analyze facial expressions may provide insight into one's condition. Developed by scientists at...
The experimental internal wound dressing incorporates both mussel adhesive protein (MAP) and silkworm-derived silk fibroin (SF). Credit: Pixaobay In the near future, mussels and silkworms could indirectly contribute to saving lives. Researchers have harnessed proteins from these creatures to create an internal wound dressing that halts bleeding and protects against infections. Typically, to stop bleeding from...
HIV is a very complicated virus, and we haven't succeeded in making a vaccine for it yet.Image credit:Canvas Since HIV first appeared, many things have changed. New medicines help people with HIV live well and stop them from spreading the virus. But to truly beat HIV, we need a vaccine.HIV is a big problem worldwide,...
'The Lawnmower' represents a groundbreaking achievement as the inaugural synthetic molecular motor capable of self-propulsion, deriving energy from its action of cutting through proteins, which are artificially generated by AI through DALL-E. The body uses tiny machines made of proteins to do important jobs. These machines help with things like cell division and moving around...
As climate change warms the planet, planning to include urban infrastructure like botanical gardens, parks, street trees, green walls and wetlands could help cool city air. Credit: Pixaobay Global temperatures are increasing, with 2023 being officially recognized as the hottest year on record. A recent study suggests that incorporating nature into urban areas could mitigate...
Lead scientist Stephanie Fraley works with one of the possibly infected blood samples used in the studyDavid Baillot/UC San Diego Jacobs School of Engineering A new technique that melts bacterial DNA in blood samples could diagnose life-threatening infections faster than before. Typically, to detect harmful bacteria in a person's bloodstream, a blood sample is cultured in...
Engineers Employ AI to Manage Fusion Power Integration into the Grid.

Nuclear fusion is key to sustainable energy, leveraging hydrogen isotopes,...
SEAS researchers have devised a multiscale strategy enabling particle-reinforced rubber to withstand high loads and deter crack propagation over multiple uses. In the image above, cracks expand in the left sample, whereas cracks in the right sample, crafted from the multiscale material, remain unchanged after 350,000 cycles.

Credit: Unsplash. New research has unveiled two or three types of magnetism, introducing the possibility of a highly sought-after magnetic property. While early compass users may have perceived magnets as mystical, the scientific understanding of magnetism has evolved. In addition to ferromagnetism and antiferromagnetism, a third type, altermagnetism, has been identified, challenging previous descriptions of...
