The results challenge the way we currently treat depression, and could lead to the first preventative therapies for the mental illness. While much research has focussed on the effects of various brain chemicals such as serotonin and dopamine on depression, for the first time, scientists from the Icahn School of Medicine in the US have found that a protein called beta-catenin (B-catenin) appears to make some people deal with stress and fend off depression better than others. Fracking Wastewater Could Encourage Formation Of Toxic Compounds During Drinking Water Disinfection. Some natural gas extraction operations have sent the highly saline water left over from hydraulic fracturing, or fracking, to wastewater treatment plants for disposal.

These plants then discharge their treated water into rivers that may feed drinking water plants downstream. A new study finds a possible problem with this process: Even when made 10,000 times more dilute, fracking wastewater can increase levels of troubling compounds formed under conditions similar to those during drinking water disinfection (Environ. Sci. 1.8 Million Americans Have Chlamydia, Report Finds. Nearly 2 million people in the United States have the sexually transmitted disease (STD) chlamydia, according to new estimates from the Centers for Disease Control and Prevention.

1.8 Million Americans Have Chlamydia, Report Finds

In a new report, researchers at the CDC analyzed information from a national survey of more than 8,000 people ages 14 to 39 who provided urine samples for STD testing for the survey. The researchers found that between 2007 and 2012, about 1.7 percent of people in this age group had a chlamydia infection, which translates to about 1.8 million infections nationwide. Bacteria in Wine May be Good for Your Health. La patata Lenape y el exceso de solanina. Hace tiempo ya te avisamos de que las patatas pueden ser tóxicas debido a una sustancia llamada solanina, que utilizan para defenderse de los insectos.

La patata Lenape y el exceso de solanina

Se concentra en las partes verdes del tubérculo (por eso es mejor quitarlas) y aumenta su concentración con el tiempo, sobre todo si no guardamos las patatas en un lugar oscuro a temperatura ambiente. ¿Lo de las patatas tóxicas te suena a leyenda urbana? Pues fueron el obstáculo que encontraron los agricultores en la década de los sesenta para conseguir la variedad perfecta, que tenía el glamuroso nombre de patata Lenape.

Conocemos la historia gracias a io9: una patata normal cuenta con entre 8 y 12 miligramos de solanina, y no suele ser peligrosa. Pero las patatas Lenape contenían hasta tres veces más. Pronto se descubrió que la patata Lenape era la culpable, y el sueño de la patata frita perfecta se desmoronó. 10 Of The Strangest Known Medical Conditions.

Artificial Intelligence Is Now Telling Doctors How to Treat You

But when a patient came in with a potentially disfiguring case of bullous pemphigoid–a rare skin condition that causes large, watery blisters–she was stumped. The medication doctors usually prescribe for the autoimmune disorder wasn’t available. Burnt out birds suggest hard work could be bad for your health. Unequal sharing of workloads in societies could leave the most industrious individuals at higher risk of poor health and prone to accelerated ageing, according to a new study of a cooperative bird in the Kalahari Desert.

Burnt out birds suggest hard work could be bad for your health

A team of scientists at the University of Exeter studied white-browed sparrow weavers, a social species in which all group members share offspring care duties, but the dominant male and female work hardest. Dominants are the only birds that breed, with dominant males singing to attract a mate and dominant females producing all of the eggs and providing most of the care for nestlings. Both dominants also invest most in fiercely defending the group's territory. In order to assess how these unequal workloads impact the health of the birds, the researchers measured the level of antioxidant protection in 93 sparrow weavers before and then again after a long breeding season.

Bee, scorpion and snake venom may hold cancer cure

Ancient healers used bee, snake and frog venom to treat a variety of ailmentsVenom itself can hurt all cells, but can also be synthesized to target cancer cellsEarly lab tests show promising results using proteins from venom and nanotechnology (CNN) -- It's ancient medicine with a sci-fi-sounding twist. A scientist at the University of Illinois, Dipanjan Pan, and his team say they may have found a way to stop cancer cell growth, according to a paper presented at the American Chemical Society conference this week. The work is in very early stages, but has shown success in stopping breast cancer and melanoma cell growth in lab tests.

Inside Life Science: Improving the Odds of Surviving Sepsis. A leading cause of death in U.S. intensive care units is sepsis, an overwhelming immune response to infection that triggers body-wide inflammation and can cause organ failure. Sepsis is challenging to diagnose and treat. Many of its early signs, such as fever and difficulty breathing, are similar to those of other conditions. 5 Ways Mountains Can Help You Lead A Happier, Healthier And Longer Life. "The mountains are calling and I must go," naturalist John Muir famously wrote back in the 19th century. And while he set off to create and protect one of today's most famous wilderness parks, Yosemite, all of that time spent in the mountains may have also led him to happiness and health. From Mount McKinley to the Matterhorn, snow-capped peaks and foggy summits have a lot more to offer than breathtaking views. Altitude may fight obesity. Before Sir Edmund Hillary summited Everest, mountaineers spent a lot of time trying to figure out how to maintain enough calories to sustain their journey to the top.

Lo que dice la ciencia para adelgazar de forma fácil y saludable: Indicadores sobre colesterol, un ejemplo real. Para contrarrestar el habitual enfoque teórico de este blog, hoy les traigo un caso práctico (totalmente real) sobre indicadores de lípidos en sangre. El otro día un amigo compartió conmigo los resultados de sus recientes análisis, que representados gráficamente eran los siguientes: Como ya podrán imaginar tras analizar los datos, mi amigo tiene tendencia a tener los valores de colesterol total (CT) y colesterol malo (LDL) elevados, así que estaba preocupado por el aumento en ambos indicadores en los resultados del año 2014 respecto al año anterior. Ultraviolet Camera Reveals the Secret Price of Sunbathing. Welcome to Forbes. Some doctors believe Twitter can drive you crazy...literally! - Seriously, Science? I don’t know about you, but I find Twitter to be the most frustrating form of social media.

(Perhaps it’s simply because I’m just not pithy enough to limit myself 140 characters.) And on top of that, now we learn that Twitter might actually be bad for your mental health. If you are worried you might be in danger of “Twitter psychosis,” you might want to compare your Twitter activity to that of this patient: “Approximately 1 year before admission, she had started to “twitter” excessively.

Sometimes, she would spend several hours a day reading and writing messages, neglecting her social relationships and, sometimes, even meals and regular sleeping hours.” The doctors treating this patient suspect that reading and trying to interpret hundreds of extremely short messages, many from spammers, induced the psychosis she experienced (see below for more details). Scientists develop nasal test for human prion disease. A nasal brush test can rapidly and accurately diagnose Creutzfeldt-Jakob disease (CJD), an incurable and ultimately fatal neurodegenerative disorder, according to a study by National Institutes of Health (NIH) scientists and their Italian colleagues.

Up to now, a definitive CJD diagnosis requires testing brain tissue obtained after death or by biopsy in living patients. The study describing the less invasive nasal test appears in the Aug. 7 issue of the New England Journal of Medicine. CJD is a prion disease. Can Acupuncture Treat Depression?


Allergies. What Happens When an Amoeba “Eats” Your Brain? 5 Ways Skin Can Signal Health Problems. Study: Fish Oil Prevents Brain Shrinkage And Cognitive Decline In Older Adults. Researchers demonstrate health risks posed by 'third hand' tobacco smoke. Research led by the University of York has highlighted the potential cancer risk in non-smokers – particularly young children – of tobacco smoke gases and particles deposited to surfaces and dust in the home. Until now, the risks of this exposure known as 'third hand tobacco smoke' have been highly uncertain and not considered in public policy.

However, a new study published in the journal Environment International, has estimated for the first time the potential cancer risk by age group through non-dietary ingestion and dermal exposure to third hand smoke. Acute glaucoma discovered to be an inflammatory disease. Researchers at the University of California, San Diego School of Medicine and Sun Yat-sen University in China have shown that acute glaucoma in mice is largely an inflammatory disease and that high pressure in the eye causes vision loss by setting in motion an inflammatory response similar to that evoked by bacterial infections.
