Many people have had some degree of gum inflammation, or gingivitis, caused by dental plaque. The gums get red and swollen, and they bleed easily. If left unchecked, the condition can progress to periodontitis. Now, an oral device in development could slowly release wild blueberry extract after deep cleaning to help treat periodontitis.
A new study suggests that exposure to certain phthalates — substances commonly used in food packaging, personal-care and other everyday products — could be associated with miscarriage, mostly between 5 and 13 weeks of pregnancy.
Scientists have developed a simple process to treat waste coffee grounds to allow them to store methane. Methane capture and storage provides a double environmental return — it removes a harmful greenhouse gas from the atmosphere that can then be used as a fuel that is cleaner than other fossil fuels.
Researchers, using computer generated simulation, have predicted the existence of a new two-dimensional carbon material, a "patchwork" analogue of graphene called phagraphene.
New research suggests that the associations we make between emotion and color go beyond mere metaphor.
A new study has revealed the presence of radioactive contaminants in coal ash from all three major U.S. coal-producing basins. The study found that levels of radioactivity in the ash were up to five times higher than in normal soil, and up to 10 times higher than in the parent coal itself because of the way combustion concentrates radioactivity.
Your heart might be older than you are. A new government report suggests age is just a number — and perhaps not a very telling one when it comes to your risk of heart attack or stroke. Nearly three out of four U.S. adults have a heart that's older than the rest of their body, according to CDC calculations.
Multiple System Atrophy, a brain disorder is caused by a newly-discovered prion linking it to incurable diseases like mad cow and Creutzfeldt-Jakob disease, according to new research. The prion link makes it the first human disease caused by the misfolded proteins to be identified in 50 years.
Frank Reyes agreed to an uncommon operation at Houston Methodist Hospital, and spent three weeks with his left hand surgically tucked under a pocket of tissue in his belly to give it time to heal and form a new blood supply. Last Thursday, doctors cut his hand free of its temporary home and shaped some of the abdominal tissue and skin to cover it.
Researchers have found that a well-known period of abrupt climate change 12,000 years ago occurred rapidly in northern latitudes but much more gradually in equatorial regions, a discovery that could prove important for understanding and responding to future climate change.
An archeologist has 3-D-printed a replica of an iron-age artifact to revive a rich musical culture in ancient Ireland. Billy Ó Foghlú, from The Australian National University (ANU), has found evidence that the artifact may have been a mouthpiece from an iron-age horn and not a spear-butt as previously thought.
It is increasingly clear that the thousands of different bacteria living in our intestinal tract - our microbiome - have a major impact on our health.But the details of the microbiome's effects are still fairly murky. A new study suggests approaching this topic from a new angle: assess how fast the various bacteria grow.
Sleeping less means more colds, researchers warn. Six hours or less per night means being four times more likely to get sick with the common cold virus, according to research published this week in the journal Sleep.
Engineers have developed a mouth guard that can monitor health markers, such as lactate, cortisol and uric acid, in saliva and transmit the information wirelessly to a smart phone, laptop or tablet. The technology, which is at a proof-of-concept stage, could be used to monitor patients continuously without invasive procedures, as well as to monitor athletes' performance or stress levels in soldiers and pilots.
The careful examination of fossil fragments from Panama has led Smithsonian scientists and colleagues to the discovery of a new genus and species of river dolphin that has been long extinct. The team named it Isthminia panamensis.
