Have you ever wondered about the colors you see in these moments? What sunlight actually is? Yes, it's light from the Sun but so much more than that. Sunlight is both light and energy. Once it reaches Earth, we call this energy, "insolation," a fancy term for solar radiation. The amount of energy the Sun gives off changes over time in a never ending cycle. Solar flares (hotter) and sunspots (cooler) on the Sun's surface impact the amount of radiation headed to Earth.

A new position statement suggests resistance training should be considered vital to improving the health and longevity of senior citizens.

The statement makes recommendations for successful resistance training, or exercise focused on building muscle endurance, programs for older adults. 

When you poll people about living past 100 years old, few respond positively. It could be loss of friends and family, physical and cognitive decline, loss of independence and poor quality of life. If physical decline were mitigated, people may not be able to live longer, but they might live better.

The most popular organic fertilizer is feces while the most popular pesticide is copper sulfate. Both of those don't sound great to ingest but a new study says that extra dung leads to more bacteria - and that may be a good thing, if you believe a lot more bacteria is beneficial to gut health.

Yogurt marketing and supplement claims aside, there is no evidence that your body is impacted by probiotics unless you suffered a legitimate medical issue (as in you need an actual fecal transplant), yet like gluten-free diets probiotic foods have become a trend among people with extra money to spend. The same people who buy organic food.

During the early Triassic period, ichthyosaurs evolved from a group of unidentified land reptiles that returned to the sea. They were particularly abundant in the later Triassic and early Jurassic periods before being replaced as premier aquatic predator by another marine reptilian group, the Plesiosauria, in the later Jurassic and Cretaceous periods.

Bisphenol S (BPS) and bisphenol F (BPF) are chemicals used in the lining of aluminum-canned food and drinks (to prevent spoilage). They were rolled out as a replacement for bisphenol A (BPA), a compound targeted by activists under claims it might statistically be an "endocrine-disrupting chemical." Exhaustive studies later found overwhelming scientific evidence that was not so.

A new paper has statistically linked depression and anxiety during pregnancy (and link preterm births due to those) to the radius of natural gas hydraulic fracturing wells in Pennsylvania.

Should you be worried? The short answer is "no", this is not a very good paper.

Just like "only in mice" has become a common complaint of biologists, chemists, and toxicologists about provocative claims designed to get media attention, "it's just correlation" is invoked nearly as often by the science community.

Yes there is much we need to do and can do. As we ramp up on pledges quickly we reduce future impacts of droughts, wild fires, hurricanes and other climate related local disasters. We will reduce the effects of sea level rise, and avert warming levels likely to lead to millions of climate migrants (chapter 3, section 3.4. 12 and Figure 3.4 page 246). These actions are also good for our economy and better for biodiversity. By staying within 1.5°C, we can save coral reefs from near extinction, and reduce the amount of adaptation needed for many ecosystems.

Compensatory strategies for kids with autism spectrum disorders, an adaptive process whereby new behaviors are generated in order to avoid negative outcomes, do have positive outcomes, like increased social integration, but can result in a barrier to diagnosis.
