 New Origami-inspired Design Turns Pushing Into Pulling
The series of paper cells developed by researchers at the University of Washington uses origami folds to absorb the force of impacts. (Credit: Kiyomi Taguchi/University of Washington)
Whether applied to auto collisions or rocket landings, absorbing energy from impacts is a valuable trait, and industries have been working on various solutions for years. For spacecraft, landing safely has entailed everything from inflatable airbag systems to sky cranes to retro-thrusters. But what if the

What's up with all this wild, weird weather — and is it linked to climate change?
Violent thunderstorms boiled up across Oklahoma, Kansas and Missouri on May 22, 2019, as seen in this animation of infrared images acquired by the GOES-16 weather satellite. Tornadoes, including one that ravaged parts of Jefferson City, MO, are indicated by blue-colored T's. (Note: The animation may take awhile to load. It's worth the wait! Source: CIMSS Satellite Blog)

Climate change affects the genetic diversity of a species
What effects does climate change have on the genetic diversity of living organisms? In a new study, researchers studied the genome of the alpine marmot. Results were unexpected: the species was found to be the least genetically diverse of any wild mammal studied to date. The alpine marmot has lost its genetic diversity during ice-age related climate events and been unable to recover its diversity since.

 New lidar instruments peer skyward for clues on weather and climate
San Jose CA (SPX) May 22, 2019
Researchers have developed a set of diode-based lidar instruments that could help fill important gaps in meteorological observations and fuel a leap in understanding, modeling and predicting weather and climate. The instruments are particularly well suited for insights on atmospheric dynamics at the mesoscale, a size range equivalent to the area of a small city up to that of a U.S. state.

Researchers have found that socioeconomic inequalities in children's body mass index (BMI) emerge during the preschool years and widen across childhood and into early adolescence. By analyzing data on height and weight (BMI) they found that lower maternal education was associated with faster gains in child body weight but lower height growth leading to a higher risk of overweight and obesity.

When macrophages are deprived of oxygen
Infected tissue has a low concentration of oxygen. The body's standard immune mechanisms, which rely on oxygen, can then only function to a limited extent. How does the immune system nevertheless manage to control bacteria under such conditions? Researchers have discovered that fewer metabolites are produced in the citric acid cycle under hypoxic conditions, leading to a reduced rate of reproduction among bacteria in macrophages.

The mystery of why Earth has so much water, allowing our "blue marble" to support an astounding array of life, is clearer with new research into comets. Comets are like snowballs of rock, dust, ice, and other frozen chemicals that vaporize as they get closer to the Sun, producing the tails seen in images.

A family of comets reopens the debate about the origin of Earth's water

Where did the Earth's water come from? Although comets, with their icy nuclei, seem like ideal candidates, analyses have so far shown that their water differs from that in our oceans. Now, however, an international team, bringing together CNRS researchers and the Paris Observatory has found that one family of comets, the hyperactive comets, contains water similar to terrestrial water.

With climate change, the Arctic tundra is likely to become drier. Lakes may shrink in size and smaller lakes may even disappear according to a new study. In western Greenland, Kangerlussuaq experienced a 28% decrease in the number of smaller lakes (those less than 10,000 square meters) and a 20% decrease in total area from 1969 to 2017. Many of the lakes that had disappeared in 1969 have since become vegetated.
