Origami-Inspired materials could Soften the blow for Reusable Spacecraft

Researchers have developed a novel solution to help reduce impact forces – for potential applications in spacecraft, cars and beyond. Space vehicles like SpaceX’s Falcon 9 are designed to be reusable. But this means that, like Olympic gymnasts hoping for a gold medal, they have to stick their landings.

Landing is stressful on a rocket’s legs because they must handle the force from the impact with the landing pad. One way to combat this is to build legs out of materials that absorb some of the force and soften the blow.

Meteor Magnets in outer space—study finds elusive Giant Planets

The ‘wobble,’ or radial velocity technique for finding planets relies on the movement of the stars created as they’re circled by their planets. The blue wave represents movement toward Earth, while the red wavelength occurs as the star heads away. Credit: (NASA/JPL-Caltech)

Astronomers believe planets like Jupiter shield us from space objects that would otherwise slam into Earth. Now they’re closer to learning whether giant planets act as guardians of solar systems elsewhere in the galaxy.

A UCR-led team has discovered two Jupiter-sized planets about 150 light years away from Earth that could reveal whether life is likely on the smaller planets in other solar systems.

“We believe planets like Jupiter have profoundly impacted the progression of life on Earth...

Dietary Cholesterol or Egg consumption do not increase the risk of Stroke, Finnish study finds

Egg consumption, cholesterol intake, and risk of incident stroke in men: the Kuopio Ischaemic Heart Disease Risk Factor StudyThe American Journal of Clinical Nutrition, 2019; DOI: 10.1093/ajcn/nqz066

A new study from the University of Eastern Finland shows that a moderately high intake of dietary cholesterol or consumption of up to one egg per day is not associated with an elevated risk of stroke. Furthermore, no association was found in carriers of the APOE4 phenotype, which affects cholesterol metabolism and is remarkably common among the Finnish population. The findings were published in the American Journal of Clinical Nutrition.

Findings from earlier studies addressing the association of dietary cholesterol or egg intake with the risk of stroke have been contradictory...

More than a Protein Factory: A Role for Ribosomes in regulating human Gene Expression

A new study using human cell lines provides insight on how instructions embedded within mRNA messages can affect mRNA levels, mRNA stability, and protein production in a translation-dependent manner.

Researchers from the Stowers Institute for Medical Research have discovered a new function of ribosomes in human cells that may show the protein-making particle’s role in destroying healthy mRNAs, the messages that decode DNA into protein.

“For a long time, many people have viewed ribosomes as a passive player in the cell – a molecular machine that’s just producing proteins,” says Stowers Assistant Investigator Ariel Bazzini, PhD. “Now there’s growing evidence that ribosomes regulate gene expression, including in human cells.”

These findings, which were rece...
