Researchers have found evidence that magnetic waves in a polar coronal hole contain enough energy to heat the corona and that they also deposit most of their energy at sufficiently low heights for the heat to spread throughout the corona.

The observations help to answer a 70-year-old solar physics conundrum about the unexplained extreme temperature of the Sun's corona – known as the coronal heating problem.

The team analyzed data from the Extreme Ultraviolet Imaging Spectrometer onboard the Japanese satellite Hinode. They used observations of a polar coronal hole, a region of the Sun where the magnetic fields lines stretch from the solar surface far into interplanetary space.  

We've become a nation of defensive medicine. Health care is expensive not because of drug companies or overpaid doctors or malpractice premiums, but rather the largest cost for health care is administering tests to check off boxes and prevent legal problems in a future lawsuit that may never come.

No medical organization recommends the prostate-specific antigen test for older men, but many primary care doctors continue to administer it even to those over age 75.

Science has come a long way since 1978, when Louise Joy Brown, the world's first successful 'test-tube baby', was born.

Despite claims that these children were somehow going to be less natural, in vitro fertilization (IVF) has instead become mainstream, along with other methods to promote successful pregnancy. An aggregation of ten international reports tracking the use of Assisted Reproductive Technologies (ART) has led the International Committee for the Monitoring of Assisted Reproductive Technology (ICMART) to estimate that there have been 5 million babies born with the help of science and technology.

The endogenous hormone dopamine, induced by joyful classics as sex, drugs and food , triggers feelings of happiness - but that is not all. It remembers the state of happiness and keeps wanting to achieve it again. Dopamine enables us to make the "right" decisions in order to experience even more moments of happiness.

If you buy supplements, alternative medicines and advertised herbal gimmicks based on the claim that they are too progressive for the FDA, you are just lacking in judgment. If you are buying the workout supplement Craze, a product widely sold across the U.S. and online, you could be in a lot more danger.

A workout supplement marketed as a 'performance fuel', Craze is manufactured by Driven Sports, Inc. It is sold in stores across the United States and internationally via body supplement websites.

An international team of scientists have identified potentially dangerous amounts of methamphetamine analog N,α- DEPEA, which has not been safely tested for human consumption, in three samples of Craze.

Researchers have found an odd statistic; people with speech and language disorders are about 3.5 times more likely to be teachers than patients with Alzheimer's dementia. 

Speech and language disorders are typically characterized by people losing their ability to communicate; they can't find words to use in sentences, or they'll speak around a word, and they may also have trouble producing the correct sounds and articulating properly. Speech and language disorders are not the same as Alzheimer's dementia, which is characterized by the loss of memory. Progressive speech and language disorders are degenerative and ultimately lead to death anywhere from 8-10 years after diagnosis.
