Smart material switches between heating and cooling in minutes

Added: 09.11.2021 22:23 | 154 views | 0 comments

Engineers have developed smart material technology that, with the flip of a switch, can alternate between harvesting heat from sunlight and allowing an object to cool. The window-like device has no moving parts and could be a boon for HVAC savings, potentially cutting energy usage by nearly 20% in the United States alone.

Neutron star collisions are 'goldmine' of heavy elements, study finds

Added: 09.11.2021 22:23 | 146 views | 0 comments

Most elements lighter than iron are forged in the cores of stars, but scientists have puzzled over what could give rise to gold, platinum, and the rest of the universe's heavy elements. study finds that of two long-suspected sources of heavy metals, one of them -- a merger between two neutron stars -- is more of a goldmine than the other.

Vitamin D deficiency for the first time visible after cremation

Added: 09.11.2021 22:23 | 150 views | 0 comments

The cremation process destroys a lot of information that can usually be obtained from the human skeleton. Especially diseases are difficult to observe. Researchers have now found a way to reveal some of the information. For the first time, they have succeeded in detecting vitamin D deficiency in cremated human remains.

VR experiment with rats offers new insights about how neurons enable learning

Added: 09.11.2021 22:23 | 155 views | 0 comments

A new study provides deep insights into how the brain's hippocampus works, involving networks of millions of neurons. That knowledge could be an important step toward the development of treatments for neurological disorders such as Alzheimer's disease, schizophrenia and epilepsy, all of which are related to dysfunction in the hippocampus.

Skin-inspired sensors show how our body moves

Added: 09.11.2021 22:23 | 143 views | 0 comments

Scientists have created wearable, stitchable, and sensitive sensors from flexible polymers and bundles of carbon fibre. Like our skin, these sensors respond to pressure and can measure body position and movement. They could be used to measure disease progress in Parkinson's disease, or sense joint movement in athletes, for example.

Rocky exoplanets are even stranger than we thought

Added: 05.11.2021 20:39 | 168 views | 0 comments

Astronomers and geologists have made the first estimates of rock types that exist on planets orbiting nearby stars. After studying the chemical composition of 'polluted' white dwarfs, they have concluded that most rocky planets orbiting nearby stars are more diverse and exotic than previously thought, with types of rocks not found anywhere in our Solar System.
