More men than women develop Parkinson’s disease and new work presented at the Federation of European Neuroscience Societies says that it is do to sex differences in how brain cells change. Parkinson’s disease affects about 9 million people and becomes increasingly prevalent with age.
Scholars recently characterized plasma levels of the biomarker dehydroepiandrosterone (DHEA) and its sulfated form (DHEAS) – jointly referred to as DHEA(S) – to be biological determinants of chemobrain, difficulties related to memory and attention in cancer patients even months after completing their treatment. DHEA(S) are neurosteroids that help to regulate brain development, but it was previously unknown whether their levels correlate with cognitive function or are associated with the onset of chemobrain. The study showed that early-stage breast cancer patients with higher plasma DHEAS levels prior to chemotherapy were found to have a lower risk of developing chemobrain in the specific domains of verbal fluency and mental acuity.
Smart spacesuits and solar surfing may sound like the stuff of science fiction, but they are just two of the technology concepts NASA ha
There is one Cthulhu it's safe to invoke; Sollasina cthulhu, obviously named after H.P. Lovecraft's tentacled monster, a 430 million-year-old fossil that has been identified as a new species related to living sea cucumbers.The new cthulhu, Sollasina, was an echinoderm (the group that includes sea urchins, sea cucumbers, and sea stars) that had 45 tentacle-like tube feet, which it used to crawl along the ocean floor and capture food. The creature was small, about the size of a large spider. It was found in the Herefordshire Lagerstätte in the United Kingdom, a site that has proven to be a trove of fossilized ancient sea animals, and included soft tissue preservation.
The discovery of an ancient painted vase in the Central America lowlands offers new clues into the mysterious breakdown of ancient Maya civilization - because it bears one of the longest hieroglyphic texts ever found.The shattered vessel was discovered in excavations at the Maya site of Baking Pot in Belize, found amid artifacts associated with the abandonment of the royal palace complex. The fragments were found in a corner near a palace entrance. The archeology team also unearthed blades, pendants, inkpots, fragments of flutes — and human bones - in burial sites.
People choose a life partner who is likely to have a comparable life expectancy and who share similar risks of illnesses - such as high blood pressure or heart disease - according to a genetic study.
The conjugative transfer of anti-antibiotic resistance genetic elements could lead to development of probiotic bacteria that re-sensitize resistant bacteria to antibiotics, providing a solution to a crucial problem - how to get new antibiotics when countries cap what companies can charge for medicine, meaning they might never be profitable.Bacteria become resistant due to the use of antibiotics and the exchange of resistance genes between bacteria.
Using records pediatric health clinics, specialized programs for children with developmental disabilities, and special education records along with a review of the abstracted evaluations by trained clinicians using a standardized case definition and method (Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR) diagnostic criteria) a new Centers for Disease Control and Prevention analysis has found that diagnoses in the sites they used were up 27 percent from 2010 to 2014.The overall ASD prevalence was 13.4 per 1,000 children aged 4 years in 2010, 15.3 in 2012, and 17.0 in 2014 but in New Jersey, the ASD diagnoses were substantially higher, 19.7,
Consumer hand sanitizers are popular, and they became more popular when brands started advertising they used the same chemicals hospitals use. FDA allowed it starting in 1994 (1994 Health Care Antiseptic
TFM (June 17, 1994, 59 FR
31402)), the same year they gave supplements exemption from real FDA oversight.
If you've swum in the ocean you know it requires a lot of energy, and for ships it is no different. Adding to that are the problems of friction, corrosion, and biofilms, all of which cause marine traveler to drag.Science is on the case. New types of ship coatings that permanently retain an air layer under water and reduce the three problems have been granted the Validation Award by the Federal Ministry of Education and Research (BMBF) in Germany.
Supplements are a huge industry that ballooned after President Bill Clinton turned the Dietary Supplement Health and Education Act of 1994 into law and took control of the controversial industry away from the U.S. Food and Drug Administration in return for a weak disclaimer that the FDA had not evaluated their claims - "This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease" all while suggesting they do exactly that.
Published in 1979 in Astronomy and Astrophysics, it had a worldwide impact, especially since this type of object was still highly theoretical. It was not an artist's view but an image based on the then supposed physical properties of a black hole and its gas disc, such as its rotation rate and temperature, and on Einstein's general theory of relativity.
An international team of over 200 scientists has captured the first direct images of a black hole. They accomplished this remarkable feat by coordinating the power of eight major radio observatories on four continents, to work together as a virtual, Earth-sized telescope.
In a series of papers published today in a special issue of Astrophysical Journal Letters, the team has revealed four images of the supermassive black hole at the heart of Messier 87, or M87, a galaxy within the Virgo galaxy cluster, 55 million light years from Earth.
All four images show a central dark region surrounded by a ring of light that appears lopsided — brighter on one side than the other.
