When you see a TV weather personality put up an air quality map for the last 10 years, it might make you believe that pollution is far worse than when you were young.
Do amputee sprinters using running prostheses, or blades, have a competitive advantage?
The world’s fastest 400-meter sprinter, Blake Leeper, was ruled ineligible to compete in the Tokyo Olympics due to having an assumed advantage, but a new study
with the most comprehensive set of data ever collected from elite runners with bilateral leg amputations compared performance data from Leeper, South African “blade runner” Oscar Pistorius and other bilateral amputee sprinters with those of the best non-amputee sprinters in the world across five performance metrics and found no advantage.
A survey of over 1,000 mothers who were part of the Understanding Parental Estrangement Survey conducted by the University of Wisconsin Survey Center in 2019 and estranged from their adult children revealed a disconnect between what the kids might say is the reason and parents believe
If you read social media, you might believe we're teetering on the brink of societal collapse due to COVID-19 but one metric tells the real health story; ICU beds.
Deaths have been cut almost in half from this time last year while ICU occupancy is down 40 percent. If you're a positive person, you'll note that this is a win and big thanks go to the health care system that critics demand be replaced by something like VA hospitals, which very few veterans agree is good, or Medicare, which very few old people think is good. You'll also note that vaccines work, and those are the product of Big Pharma that similar critics decry as greedy evil opportunists.
Early-onset scoliosis is a potentially deadly curve in the spine that can damage a child’s heart and lung function as it progresses. Adolescents with scoliosis are traditionally treated with a single spinal fusion, where rods and screws are inserted to fuse the spine in a straighter position.
Parents want to make informed choices and a new study
finds that preadolescent children with severe neuromuscular scoliosis who are treated with growth-friendly surgery prior to spinal fusion have more complications and unplanned subsequent surgeries than those who only have the spinal fusion.
It is well-known that the gravity from the moon impacts ocean tides, sailors knew it long before anyone knew what gravity even was. A new
literature review and small meta-analysis
hopes to add to the body of work showing how much gravity impacts plants and animals as well. The meta-analysis was of three previously published cases in which gravitational causality was not fully explored: the swimming activity of isopods, small shell-less crustaceans whose appearance on Earth dates from at least 300 million years ago; reproductive effort in coral; and growth modulation in sunflower seedlings inferred from autoluminescence.
Cancer deaths rose to 10 million globally in 2019, up from 2010 when total cancer deaths numbered 8.29 million worldwide - but the headline masks some important health progress.
Cancer is not going up, despite claims by those who believe modern food, energy, and medicine are harming us. Diagnoses are going up, which means deaths are now more successfully categorized than in the past. And tracheal, bronchus, and lung cancer, the leading causes, will decline as the inroads America has made against smoking propagate throughout Europe and developing nations.
In the 1966 Harry Harrison novel "Make Room! Make Room!" concerns about population control were the driver of the plot and the storytellers were various people in New York City when the world has reached a population of 7 billion. You have probably never heard of the novel, but you likely have heard of the movie version, "Soylent Green", starring the incomparable Charlton Heston.
The neutron, discovered in 1932 by Chadwick, is a fascinating particle whose existence allows for the stability of heavy nuclei and a wealth of atoms of different properties. Without neutrons, Hydrogen would be the only stable element: protons cannot be brought together and bound in a stable system, so e.g. Helium-2 (an atom made of two protons with two electrons) is very short-lived, as are atoms with more protons and no neutrons. So our Universe would be a very dull place.
