When scientists exposed pregnant mice to levels of bisphenol A equivalent to those considered safe in humans, three generations of female mouse offspring experienced significant reproductive problems, including declines in fertility, sexual maturity and pregnancy success.
The rapid increase in use of e-cigarettes has led to heated debates between opponents who question the safety of these devices and proponents who claim the battery-operated products are a useful cessation tool. A new study suggests proponents are in error.
Researchers, in an effort to grow placenta cells to better study the causes of pre-eclampsia, serendipitously discovered a previously unknown form of human embryonic stem cell. They say these new stem cells can help advance research on pre-eclampsia and a number of other areas of the human reproductive process.
A team analyzed teeth of children and adults from two 19th century cemeteries, one in Ireland with victims of the 1845-52 famine and one in England that held people who fled the deprivation. The composition of teeth that were forming in the womb, and during a child’s early years, not only provided insight into the health of the mother, it even showed differences between those infants who died and those who survived beyond early childhood.
Mark Phillips, the founder of Palcohol— the company behind powdered alcohol— is preparing to soon begin selling the product, which makes vodka and rum drinks or cocktails when mixed with water. But first, Phillips must convince skeptical lawmakers from Hawaii to Maine, who are working frantically to keep powdered alcohol off limits.
If you’ve ever sat opposite a doctor and wondered what she was scribbling on her notepad, the answer may soon not only be medical notes on your condition, but real-time chemical preparations for an instant diagnostic test. Thanks to new work, chemicals formed into pencils can be made to react with one another by simply drawing with them on paper.
Humans may be able to communicate positive emotions like happiness through the smell of our sweat, according to new research that indicates we produce chemical compounds, or chemosignals, when we experience happiness that are detectable by others who smell our sweat. The study also showed that being exposed to sweat produced under happiness induces a contagion of the emotional state.
A California vaccination bill that has generated intense debates pitting personal rights against public health stalled in the state Senate, with lawmakers saying it could unconstitutionally deprive unvaccinated children of an adequate education by barring them from schools. The measure would bar parents from seeking vaccine exemptions for their children because of religious or personal beliefs.
Soldiers who suffer internal trauma from explosions might one day benefit from a new treatment now under development. Researchers have reported that injecting a certain type of nanoparticle helped reduce lung damage in rats experiencing such trauma.
Some consumer groups concerned about the safety of synthetic preservatives such as parabens have pushed for natural alternatives. Industry has responded with a slew of options, including preservatives from kimchi, a popular Korean staple. But scientists have found that a “natural” preservative made from radish kimchi contains synthetic ingredients.
New research suggests that southpaws may be protected from one of the common after-effects of a severe stroke because of differences in their brain networks.
Researchers have used MRI video to determine what happens inside finger joints to cause the distinctive popping sounds heard when cracking knuckles. For the first time, they observed that the cause is a cavity forming rapidly inside the joint.
Diabetes that develops early in pregnancy may increase women's chances of having a child with autism, according to a new study. The risk was seen in young children whose mothers were diagnosed with diabetes during the most crucial period of fetal brain development.
Educational standards and practices differ vastly from country to country. In the face of arguments over the U.S.’ standardized testing and Finland’s abandonment of subjects, one wonders how academic prowess relates to culture and the quality of life.
Neanderthals from the French region of Poitou-Charentes cut, beat and fractured the bones of their recently deceased companions, as revealed by the fossil remains of two adults and a child found at the Marillac site. These manipulations have been observed at other Neanderthal sites, but scientists still do not know whether they did this for cannibalism or ceremony.
Exercise researchers have developed a new treadmill that automatically changes speed to match the pace of the runner. The automated treadmill uses sonar to tell exactly where the runner is.
The environment of the womb, which is determined by a mother's health, lifestyle and surroundings, can alter the development of a fetus with permanent and lifelong implications. We've long known that a pregnant mother's alcohol and tobacco use can harm a developing fetus but, now, researchers are learning much more about how a baby's first nine months before birth can affect its health into adulthood.
A natural compound derived from the bark of the magnolia tree, can protect a mouse's heart from hypertrophy, a thickening of cardiac muscle often caused by chronic high blood pressure that can lead to heart failure.
There has long been interest in using genetically engineered microbes to target and destroy cells within solid tumors. Now, a study has demonstrated that genetically modified Salmonella can be used to kill cancer cells.
Researchers have shown that polyphenols in green tea and apples block a signaling molecule called VEGF, which can trigger atherosclerosis and is a target for some anti-cancer drugs.
No mention of King Richard III's distinctive physique survives from during his lifetime, perhaps out of respect to a reigning monarch, or perhaps because he hid it so well. In a new study, researchers argue that, as with all monarchs, Richard’s body image in life was carefully controlled and he probably kept any signs of his scoliosis hidden outside of the royal household– up until his death.
Steaks and chops could be pushed to the high-end of the meat market in the future, with artificial meats supplying the bulk, cheap end, research suggests. The review examined potential impacts of in vitro meat, plant, fauna and fungal-based meat alternatives, genetically modified animals and cloning.
The human immune system can handle large bursts of HIV activity and so it should be possible to cure HIV with a “kick and kill” strategy. The kick and kill strategy aims to cure HIV by stimulating the immune system with a vaccine, then reawakening dormant HIV hiding in white blood cells with a chemical kick so that the boosted immune system can identify and kill them.
Researchers studying the commonly used pain reliever acetaminophen found it has a previously unknown side effect: it blunts positive emotions. In the study, participants who took acetaminophen reported weaker emotions when they saw both very pleasant and very disturbing photos, when compared to those who took placebos.
Researchers have developed the first drug test printed on paper. They used antibodies as morphine sensing molecules when creating this printing technology-based morphine test. Using printing technology to manufacture rapid tests enables high production volumes and low production costs.
