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...
Scientists are creating a robotic exoskeleton platform to address the constraints of treadmills utilized in the rehabilitation of stroke survivors experiencing walking difficulties.
Mark found out he had ALS in 2020, and he's already lost a lot of his ability to move, like using his phone or eating by himself. Image Credit CNN Mark, who is 67 years old, found out he had ALS in 2020. Over time, he's been losing his ability to do things like using...
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...
A microbial fuel cell buried in soil and generating powerBill Yen/Northwestern University A groundbreaking innovation from Northwestern University showcases a compact device capable of producing electricity by harnessing the power generated as microbes decompose soil, as long as there is carbon present. This device, about the size of a paperback book, operates on microbial fuel...
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...
Punyo is a torso-up soft humanoid robot designed to pick things up using its arms, chest and shoulders instead of just its handsToyota Research Institute The majority of humanoid robots typically use their hands to pick up objects, but this method doesn't mimic human behavior accurately, especially when dealing with bulky items. Humans utilize not...
Shadows cast during a partial eclipse. Image source: Yvonne Hanson/Shutterstock.com A recent study discovered that certain types of clouds vanish during solar eclipses, shedding light on why it happens. This finding might affect efforts to control the climate. During solar eclipses, people have noticed that regular cumulus clouds over land disappear quickly. The lead author of...
On the left is Hylaeus derectus, and on the right is Hylaeus navai, both are among the newly discovered species found in Fiji. Back in the 1930s, a scientist named Elwood Zimmerman found three very small, pretty bees on tahetahe flowers in Polynesia. People were amazed because these bees were so far away from other...
