The subtle ways a lack of vitamin D affects you
As winter approaches in the northern hemisphere and the days get darker, our bodies are suffering more than we realise. We need sunlight on our skin to produce the vital vitamin D, which is important for bone and muscle health and immune function, but there’s just not enough strength in the sun at this time of year to do it.

Scientists May Have Cracked the Mystery of the Moon’s Unequal Hemispheres
Chang’e-6 samples suggest the Moon’s two very different sides may have formed when uneven heating drove magma from one hemisphere to the other. The Moon presents two dramatically different faces. Its Earth-facing hemisphere is rich in dark volcanic plains, while the farside is dominated by older highlands and a much thicker crust. New analyses of

Earth Will Become One Big Supercontinent Again—And It Will Probably Kill Us, Scientists Say
In 200 million years, there will be no borders–and possibly no humans.
Scientists who read 16 years of radio tracking from three Mars orbiters say the mantle beneath the planet's southern highlands runs 200 to 400 degrees Celsius hotter, averaged over the whole depth of the mantle, than the mantle beneath the northern plains, an inference drawn from the way Mars flexes under the Sun across each Martian year
The tracking shows Mars deforming in a way a uniform planet should not, and the least strained explanation is a hemisphere of mantle that something is still keeping warm.
US Proposal To Eliminate PAHO Funding Raises Alarm Over Health Security In Western Hemisphere

Hubble tracks new decagon encircling Saturn’s south pole
Recent observations with the NASA/ESA Hubble Space Telescope have revealed a giant, evolving 10-sided atmospheric wave encircling Saturn’s south pole. This discovery marks the first time a large regular-sided jet pattern has been observed in the planet’s southern hemisphere. The feature appears remarkably similar to Saturn’s famous hexagon at its northern pole, but is also distinctly different, suggesting scientists may be witnessing a new atmospheric phenomenon develop on the iconic gas giant.

Where the Trump Administration's Global Health Agreements Stand
The State Department has now signed more than 30 bilateral global health cooperation agreements, adding dozens of new deals with partner governments since our initial update and rundown of outstanding questions in December. And as the administration works to reorient the geographic focus of US assistance, the sweeping new agreements have reached the Western Hemisphere and the Indo-Pacific. Beyond signing additional agreements, the State Department published the official texts of five memoranda of understanding (MOUs) in response to a FOIA request, only to quietly disappear from the government's website. (Public Citizen maintains separate copies—along with other MOU-related documents from unofficial sources.)

China’s Chang’e-6 reveals why solar wind hits the Moon’s two sides differently
China’s Chang’e-6 samples have uncovered a surprising difference between the Moon’s two hemispheres. Solar wind particles penetrated deeper into the far-side soil because Earth’s magnetosphere slows the particles that reach the near side. Noble gases locked inside the lunar regolith preserved evidence of this uneven bombardment. These gases may even help scientists reconstruct the ancient history of Earth’s magnetic shield.
Happy Independence Day Dawg Sports!
It’s July 4th, the day we celebrate one of history’s earliest and most impactful conference realignments.

This strange giant dinosaur may change what we know about Jurassic titans
A bizarre new giant dinosaur discovered in Argentina is giving paleontologists a fresh look at how Jurassic titans evolved in the Southern Hemisphere. Bicharracosaurus dionidei stretched about 20 meters long and carried a strange mix of features seen in both Diplodocus and Brachiosaurus relatives. Scientists believe it could represent the first known Jurassic brachiosaurid from South America, helping fill a major gap in the dinosaur fossil record.
