NASA buying Moon dust for $1

The US space agency NASA awarded contracts to four companies on Thursday to collect lunar samples for $1 to $15,000, rock-bottom prices that are intended to set a precedent for future exploitation of space resources by the private sector.

Tapping overlooked marketing data to drive business growth

Researchers from University of Houston, Columbia University, Emory University, and University of Connecticut published a new paper in the Journal of Marketing that reviews factors that contribute to the disconnect between the data companies create and the productive use of that data.

Research leads to better modeling of hypersonic flow

Hypersonic flight is conventionally referred to as the ability to fly at speeds significantly faster than the speed of sound and presents an extraordinary set of technical challenges. As an example, when a space capsule re-enters Earth's atmosphere, it reaches hypersonic speeds—more than five times the speed of sound—and generates temperatures over 4,000 degrees Fahrenheit on its exterior...

Leaf microbiomes are a neighborhood affair in northern forests

Forest leaves are teeming with bacterial life—but despite the vast extent of bacteria-covered foliage across the world, this habitat, known as the phyllosphere, remains full of mysteries. How do bacteria spread from tree to tree? Do certain types of bacteria only live on certain types of trees?

Tree lifespan decline in forests could neutralize part of rise in net carbon uptake

Accelerating tree growth in recent years has been accompanied by a reduction in tree lifespan, which could eventually neutralize part of the increase in net uptake of carbon dioxide (CO2). This trade-off between tree growth and life expectancy applies to forests worldwide, including in the Amazon and other tropical regions, as well as temperate regions and the Arctic.

How proteins find their place in the cell

Over a quarter of all proteins in a cell are found in the membrane, where they perform vital functions. To fulfill these roles, membrane proteins must be reliably transported from their site of production in the cell to their destination and correctly inserted into the target membrane. Researchers from the Heidelberg University Biochemistry Center (BZH) have succeeded in determining the...

Red Sea turtle hatchlings are feeling the heat

Analyses by KAUST researchers of sand temperatures at marine turtle nesting sites around the Red Sea indicate that turtle hatchlings born in the region could now be predominantly female. These findings hold significant implications for the survival of marine turtle species as temperature increases take hold, driven by anthropogenic climate change.
