Less than 40% of the results of clinical trials conducted at leading academic medical centers were shared within two years of completion, finds a study in the British Medical Journal.

New research published in Scientific Reports in February indicates that a warm ocean surface water prevailed during the last ice age, sandwiched between two major ice sheets just south of Greenland.
Extreme climate changes in the past
Ice core records show that Greenland went through 25 extreme and abrupt climate changes during the last ice age some 20.000 to 70.000 years ago. In less than 50 years the air temperatures over Greenland could increase by 10 to 15 °C. However the warm periods were short; within a few centuries the frigid temperatures of the ice age returned. That kind of climate change would have been catastrophic for us today. (link)

Rutgers scientists have taken a step toward understanding how sexual aggression alters the female brain.
In a recent study in Scientific Reports, lead author Tracey Shors, professor in the Department of Psychology and Center for Collaborative Neuroscience in the School of Arts and Sciences, discovered that prepubescent female rodents paired with sexually experienced males had elevated levels of stress hormones, could not learn as well, and expressed reduced maternal behaviors needed to care for offspring.

It's a well-known fact that aging can lead to losing one's senses: vision, smell, hearing, touch, and taste. In previous studies, researchers have learned about the consequences of experiencing a decline in a single sense. For example, losing senses of smell, vision, and hearing have all been linked to cognitive decline, poor mental health, and increased mortality. Losing the sense of taste can lead to poor nutrition and even death in certain instances. However, until now little has been known about losing multiple senses. In a new study, researchers examined how often multisensory losses occur and what their impact on older adults might be.

Synthetic cathinones which produce effects similar to amphetamines and have been associated with numerous fatalities are derived from cathinone, which is present in the khat plant.
Only supplement makers and buyers think if it happens in nature it must be okay, but the U.S.  Drug Enforcement Administration (DEA)  has a hard time keeping up. They can only ban specific  synthetic cathinones, and did in 2011, but change a molecule and new designer drugs continue to appear, and they aren't banned because they are different.

Montreal, February 19, 2016 - Having an occasional drink is fine, but "binge" drinking is a known health hazard and now high blood pressure may need to be added to the list of possible consequences. Young adults in their twenties who regularly binge drink have higher blood pressure which may increase the risk of developing hypertension, concludes a study conducted by researchers at the University of Montreal Hospital Research Centre (CRCHUM).
Binge drinking (i.e. consuming five or more alcoholic beverages in less than two hours), is quite prevalent: previous studies in Canada and the U.S. have shown that about four in ten young adults aged 18 to 24 are frequent binge drinkers.

Suetsugu Kenji, a Project Associate Professor at the Kobe University Graduate School of Science, has discovered a new species of plant on the subtropical Japanese island of Yakushima (located off the southern coast of Kyushu in Kagoshima prefecture) and named it Sciaphila yakushimensis. This research was published on 20th February in the Journal of Japanese Botany.
Certain plant species known as mycoheterotrophic plants have abandoned photosynthesis and instead live as parasites, exploiting their fungal hosts for nutrients. However, these parasitic plants are small and only appear above ground when they are in flower or fruit, so accurate information on their distribution is limited.

The renowned 'Animas', two marble heads considered one of the most important works of baroque sculptor, painter and architect Gian Lorenzo Bernini's youth, are not a representation of a Christian soul's personification enjoying the pleasures of the Heaven or tormented by the punishment received in Hell (as believed until now), but they really are mythologically themed sculptures: a nymph and a satyr, respectively.

Long before the dinosaurs, hefty herbivores called pareiasaurs ruled the Earth. A detailed investigation of all Chinese specimens of these creatures - often described as the 'ugliest fossil reptiles' - has been published in the Zoological Journal of the Linnean Society.
Pareiasaurs have been reported from South Africa, Europe (Russia, Scotland, Germany), Asia (China), and South America, but it is not known whether there were distinct groups on each of these continents.

Soybean farmers in the United States can choose from a “candy store” of hundreds of varieties of soybean seed—high-yielding seed with proven performance traits for every region and latitude. Not so in Africa. For a variety of political reasons, soybean farmers either only have access to a few seed varieties with an unimpressive yield potential, or a few high-yielding varieties for which no performance data exists for their latitude and altitude. That may change, thanks to a new cultural fortitude which resists being controlled by Europe and a new coordinated soybean variety evaluation program to help give African growers more and better seed options.

Though it was once common to claim that red meat caused heart disease, those turned out to be flawed epidemiological conclusions based on observational studies and things like food diaries. A new study finds red meat metabolite levels high in acute heart failure patients, and seeks to re-establish the link between red meat and heart disease using biological markers. Patients with acute heart failure often have high levels of the metabolite trimethylamine N-oxide (TMAO) and red meat is a dietary source. Red meat is a source of L-carnitine which is broken down by gut bacteria to form TMAO. Some papers have linked TMAO with mortality risk in chronic heart failure but no association in acute heart failure has been established.

Survey data find that homeopathic purchases are primarily made by a small segment of the U.S. population for common, self-limited conditions such as the common cold or back pain. Though they can't do anything, a survey in the American Journal of Public Health finds that those who report visiting homeopathic practitioners find the use of these products helpful and that they also tend to pay for complementary and integrative medicine (CIM) gimmicks - even more so than users of supplements do.
