A very large study of trends in human height. The US saw and early increase (better nutrition?), but then a leveling. The Netherlands leads the world for men and Latvia for women. Many reports are self-reported - this is considered robust as the measurement technique was not self reported and the method was similar.
The contributor list is enormous - like a particle physics paper. Presentation could be better, but the overview piece gives the gist.
Although the underlying physics of phenomena that we can observe on Earth has been worked out to a good-enough level, the details of understanding how to use that physics is still far from solved - it is very easy to find things like bicycles, chaotic flow and the like that range from very difficult to too difficult with our current tools.
PIXL: The Planetary Instrument for X-ray Lithochemistry: This X-ray fluorescence spectrometer will enable high resolution analysis of soil samples. The Mars 2020 mission will also package and cache the soil samples it collects for a later potential sample return mission.
RIMFAX: The Radar Imager for Mars' subsurFAce eXperiment generates powerful ground-penetrating radar that will probe below the rover to a depth of several dozen meters.
MEDA: The Mars Environmental Dynamic Analyzer, this instrument package will provide extensive meteorological measurements, including wind direction, speed, temperature, pressure, humidity, and dust particle shape and size during dust storms.
MOXIE: The Mars Oxygen ISRU Experiment (yes, an acronym containing acronyms!) will test the ability for future astronauts to "live off the land," producing oxygen from carbon dioxide drawn from the tenuous Martian atmosphere.
SHERLOC: The Scanning for Habitable Environments with Raman and Luminescence for Organics and Chemicals. This is the potential "life-finder," which will utilize fine scale UV-imaging in the search for organic compounds.
SuperCam: This instrument will image and analyze the chemical composition of the surrounding terrain, as well as detect the presence of organic compounds in rocks and regolith from a distance.
A new and improved stereoscopic imaging system known as Mastcam-Z will also scan the terrain around the rover in high-definition detail. Though previous rovers weren't meant to scan the skies, they've proven to be serendipitous Martian astronomers as well, nabbing images of the fleeting Martian moons.
Focusing on a close double star to cut costs. With a super tight funding environment, the PIs decided to take it to the public, after all - it is very sexy, and give about half the observing time to amateurs and students.
The researchers made the discovery after fitting 800 people with blood glucose monitors for a week. The people ate standard breakfasts supplied by the researchers. Although the volunteers all ate the same food, their blood glucose levels after eating those foods varied dramatically. Traits and behaviors such as body mass index, sleep, exercise, blood pressure, cholesterol levels and the kinds of microbes living in people’s intestines are associated with blood glucose responses to food, the researchers conclude.
Those findings indicate that blood sugar spikes after eating depend “not only on what you eat, but how your system processes that food,” says Clay Marsh, an epigenetics researcher at West Virginia University in Morgantown.
Such individual differences have been noticed in previous studies, says study coauthor Eran Elinav, an immunologist at the Weizmann Institute of Science in Rehovot, Israel. While previous studies dismissed the differences as flukes, “we’re actually quantifying it,” Elinav says. For instance, eating bread produced a postmeal blood sugar level rise of 44 milligrams per deciliter of blood per hour on average. But some people’s blood sugar rose as little as 15 mg/dl*h, while others had a spike as high as 79 mg/dl*h after eating the same amount of bread.
