Miscarriage is commonly believed to be rare and its causes are misunderstood. This can lead to a guilt-ridden experience for women who have one, according to a new national survey presented 
at the American Society for Reproductive Medicine (ASRM) in Boston. 

This national population-based survey included 1,083 men and women over 18 in the U.S. Researchers analyzed a questionnaire that contained 23 questions about personal experiences and beliefs about miscarriage, possible causes and frequencies of miscarriages, as well as the emotional impact of a miscarriage. Factors impacting survey responses included gender, race, religious beliefs, education level and socioeconomic status.

Dear Science 2.0 writers:

Do any of you want to collaborate on developing a Science, Play and Research Kit (SPARK)? Here's the press release:

Worrisome news for retired American football players.  Though former players in a new preliminary study were not diagnosed with any neurological condition, brain imaging tests revealed unusual activity that correlated with how many times they had left the field with a head injury during their careers - profound abnormalities, the authors note.

When most people think of the Antarctic, they think of snow, ice and glaciers - but the continent and surrounding waters are littered with fiery volcanoes.

The Marie Byrd Seamounts in the Amundsen Sea are not active, like many volcanoes there are. Their summit plateaus are today at depths of 2400-1600 meters but, because they are very difficult to reach with conventional research vessels, they have hardly been explored.

What is intriguing is that they do not fit any of the usual models for the formation of volcanoes. Now geologists from GEOMAR Helmholtz Centre for Ocean Research Kiel were able to find a possible explanation for the existence of these seamounts on the basis of rare specimens. 

A new analysis of data on over 3,000 elderly Americans strongly suggests that people over the age of 75 with normal cognition who used diuretics, angiotensin-1 receptor blockers (ARBs) and angiotensin-converting enzyme (ACE) inhibitors showed a reduced risk of AD dementia by at least 50 percent. In addition, diuretics were associated with 50 percent reduced risk in those in the group with mild cognitive impairment.

Beta blockers and calcium channel blockers did not show a link to reduced risk, the researchers reported.

Alzheimer's disease is a public health issue in aging population and the most common cause of intellectual and social decline.

You wouldn't think the brightest exploding stars ever discovered in the universe could need some light shed on them, but they got it anyway.

A new paper proposes that the most luminous supernovae – exploding stars – are powered by small and incredibly dense neutron stars, with gigantic magnetic fields that spin hundreds of times a second.

Scientists observed two super-luminous supernovae for more than a year. Contrary to existing theories, which suggested that the brightest supernovae are caused by super-massive stars exploding, the findings suggest that their origins may be better explained by a type of explosion within the star's core which creates a smaller but extremely dense and rapidly spinning magnetic star.

Food, medicine and energy are three of the most crucial problems we face today - and they are all protested by a common demographic.

Science tends to think on the supply side - how to feed more people, how to get energy to everyone, how to save lives - while anti-science activists promote mitigation and rationing and retreating into the past. They believe in 13th century energy that hasn't worked, like wind power, unproven herbal medicines and a food system where only the agricultural 1% will be able to eat.

Schizophrenia patients often suffer from a breakdown of organized thought, accompanied by delusions or hallucinations - neuroscientists have observed the neural activity that appears to produce this disordered thinking and found that mice lacking the brain protein calcineurin have hyperactive brain-wave oscillations in the hippocampus while resting, and are unable to mentally replay a route they have just run, as normal mice do.

A new paper says that babies can tell when something is wrong — as early as 18 months.

The intermediate Palomar Transient Factory (iPTF) was developed to help scientists learn more about the complex nature of celestial objects in the universe and began searching the skies for certain types of stars and related phenomena in February.
