Planetary scientists from Brown University have developed a new remote sensing method for studying olivine, a mineral that could help scientists understand the early evolution of the Moon, Mars and other planetary bodies.

“Olivine is understood to be a major component in the interiors of rocky planets,” said Christopher Kremer, a Ph.D. candidate at Brown University and lead author of a new paper describing the work. “It’s a primary constituent of Earth’s mantle, and it’s been detected on the surfaces of the Moon and Mars in volcanic deposits or in impact craters that bring up material from the subsurface.”

Current remote sensing techniques are good a...

A key step in the immune system’s response to allergens has been uncovered by researchers at Massachusetts General Hospital (MGH). They have shown that a neuropeptide called Substance P is released by certain neurons in the skin when they detect allergens, and that this substance is essential in the development of allergen-induced immune responses. This research could lead to the development of new and better methods to treat and prevent allergies.

How allergens are detected by the immune system had not been known...

Researchers have designed a smart fabric that can detect non-metallic objects ranging from avocadoes to credit cards, according to a study from Dartmouth College and Microsoft Research. The fabric, named Capacitivo, senses shifts in electrical charge to identify items of varying shapes and sizes.

A study and demonstration video describing the sensing system were presented at the ACM Symposium on User Interface Software and Technology (UIST 2020).

“This research has the potential to change the way people interact with computing through everyday soft objects made of fabrics,” said Xing-Dong Yang, an assistant professor of...

An additional planet between Saturn and Uranus was kicked out of the Solar System in its infancy. New work led by Carnegie’s Matt Clement reveals the likely original locations of Saturn and Jupiter. These findings refine our understanding of the forces that determined our Solar System’s unusual architecture, including the ejection of an additional planet between Saturn and Uranus, ensuring that only small, rocky planets, like Earth, formed inward of Jupiter.

In its youth, our Sun was surrounded by a rotating disk of gas and dust from which the planets were born...
