“Living-dead” bacteria exist in limbo: biologically active but not proliferating. Buried in this zombie state, disease-causing bacteria could come back from the dead to re-infect patients. Researchers have produced the first evidence of this strange phenomenon in tuberculosis, suggesting new avenues for treatment.
Millions of genetically modified mosquitoes could be released in the Florida Keys if British...
The inaccuracy of forecasts has personal implications for people around the world, leaving them...
Forensic experts began excavating graves and examining bones this weekend in a tiny chapel in Madrid, hoping to solve the centuries-old mystery of exactly where the great Spanish writer Miguel de Cervantes was laid to rest. The author of "Don Quixote" was buried in 1616 at the Convent of the Barefoot Trinitarians in Madrid's historic Barrio de las Letras, but the exact whereabouts of his grave within the convent chapel are unknown.
About 30 percent of U.S. adults reported not regularly getting a sufficient amount of sleep, a 2012 CDC survey found. Sleep deficiency has been linked to increased risk of automobile crashes, chronic disease and early mortality. Giving employees more control over their work schedules may help curb sleep deficiency.
The umami taste could have an important and beneficial role in health, according to a new study. Research also found that kokumi substances, which modify flavor, could improve the taste of low-fat foods.
The editors of Laboratory Equipment want you to start your week with a smile of your face. With years of science experience, we've heard every science joke there is. So, here’s a science joke you might like. Q: What happened when a physicist ate pasta and antipasti?
Approximately 170,000 people die from alcoholic cirrhosis of the liver in Europe every year. Although alcohol is the most important risk factor, less is known about the significance of different patterns of drinking. Now, investigators have established that alcohol drinking pattern has a significant influence on the risk of cirrhosis and that daily drinking increases that risk compared with drinking less frequently.
Stress hormones in the mother can affect fetal development. Researchers found that increased levels of glucocorticoid stress hormones in pregnant mice caused the mother to eat more but reduced the ability of the placenta to transport glucose to her fetus.
Lori Simons took the bright orange pill at 3 a.m. Eight hours later, doctors sliced into her brain, looking for signs that the drug was working. She is taking part in one of the most unusual cancer experiments in the nation. With special permission from the FDA and multiple drug companies, a hospital is testing medicines very early in development and never tried on brain tumors before.
A revolutionary device has been shown to significantly lower blood pressure among patients with uncontrolled high blood pressure, compared to those treated with usual drug measures. The device is a paper clip-sized implant that is inserted between the artery and vein in the upper thigh, in a procedure lasting around 40 minutes under local anesthetic.
The process of converting the sun’s energy into liquid fuels requires a sophisticated, interrelated series of choices. Now, scientists have outlined a tool to help engineers better gauge the overall yield, efficiency and costs associated with scaling solar-fuel production processes up into large-scale refineries.
The evidence to date suggests that up to 1 percent of all children in the UK have blood markers for celiac disease, an autoimmune reaction to dietary gluten from wheat, barley and rye. While the numbers of new cases diagnosed in infants and toddlers remained fairly stable across all four countries, diagnoses among children older than two years almost tripled in the space of 20 years.
New research suggests pre-Homo human ancestral species, such as Australopithecus africanus, used human-like hand postures much earlier than was previously thought. Anthropologists have produced the first research findings to support archaeological evidence for stone tool use among fossil australopiths 3-2 million years ago.
New research may help millions stick to a common resolution: quitting smoking. Scientists are working on a nicotine vaccine that could put an end to the addiction.
“Can he hear me?” Family members are desperate to know the answer to this question when a loved one with a traumatic brain injury is in a coma. A new study shows the voices of loved ones telling the patient familiar stories stored in his long-term memory can help awaken the unconscious brain and speed recovery from the coma.
Many health advocates advise people to eat an orange and drink water rather than opt for a serving of sugary juice. But, scientists are reporting that the picture is not clear-cut.
While the link between salt and hypertension is well known, scientists haven’t understood how high salt intake increased blood pressure. Now, by studying the brains of rats, researchers have discovered that ingesting large amounts of dietary salt causes changes in key brain circuits.
Consumers perceive that organic cow milk differs from conventionally produced milk and that these differences justify the premium price for organic milk. But, in terms of nutrients in milk, there is nothing distinct about organic milk that makes it unique from conventionally produced milk once the different factors that influence milk production are taken into consideration.
Researchers have studied the stability of diverse arsenic species found in edible marine algae and have established the best conditions for their storage and preservation.
Upending decades-old dogma, a team of scientists say enzymes— long categorized as promoting cancer— are, in fact, tumor suppressors and that current clinical efforts to develop inhibitor-based drugs should instead focus on restoring the enzymes' activities.
As many as 1.4 million Americans suffer from inflammatory bowel disease. A new study has demonstrated that mice deficient for a component of the immune system, a protein called MyD88, are more susceptible to contracting a severe IBD-like illness.
Using certain electronic cigarettes at high temperature settings could potentially release more formaldehyde, a cancer-causing chemical, than smoking traditional cigarettes does, new lab tests suggest. The research does not prove a health risk— it involved limited testing on just one brand of e-cigarettes and was done in test tubes, not people.
Research combining experimental work and detailed molecular simulations has revealed, for the first time, the complex role that water plays in collagen— a protein that is a component of tendons, bone, skin and other structural tissues in the body.
Scientists recreated the energy released from an extraterrestrial collision with Earth that occurred around the time that dinosaurs became extinct. They found that the intense, but short-lived, heat near the impact site could not have ignited live plants, debunking the theory that the impact led to global firestorms.
Taking antibiotics for diarrhea may put travelers visiting developing parts of the world at higher risk for contracting superbugs and spreading these daunting drug-resistant bacteria to their home countries. This is according to a new study that calls for greater caution in using antibiotics for travelers’ diarrhea, except in severe cases.
This week’s Scientist of the Week is Ola Benderius from Chalmers Univ. of Technology. He and a team solved a 70-year-old driving mystery: why do people jerk the wheel?
New research provides further evidence that the benefits of fish consumption on prenatal development may offset the risks associated with mercury exposure. In fact, the new study suggests that the nutrients found in fish have properties that protect the brain from potential toxic effects of the chemical.
