3:00 PM | This Guy Uses Specialized Molds to “Grow” Furniture (Pictures/Video)
British designer Gavin Munro is taking a fresh new look at how furniture is created. Rather than cutting trees down to craft them into furniture, Munro decided to let nature do all the work as the trees grow. He calls it “Full Grown Furniture“. Using specialized plastic molds, Munro directs the growth of young trees, regularly pruning them and gently guiding them in the right direction when necessary. He also uses grafting to bind branches together, making […]

2:34 PM | Bees and neonicotinoids – another twist in the tale.
To the agrochemical companies and to many farmers they are essential tools ensuring efficient crop production. To environmentalists and to many bee scientists they are dangerous chemicals contributing to declining bee populations. I am talking, of course, about the neonicotinoid insecticides widely used in this country to control insect pests. Last week two papers were … Continue reading Bees and neonicotinoids – another twist in the tale. →

1:47 PM | Diabetes Drug Metformin Linked To Intersex Fish
Metformin, a medication commonly taken for Type II diabetes, is being found in freshwater systems worldwide, and a new study says that it causes physical changes in male fish exposed to doses similar to the amount in wastewater effluent. It causes intersex in fish - male fish that produce eggs - according to the study in Chemosphere. Because intersex fish occur more often downstream from wastewater treatment plants, studies have investigated the effect of hormones from birth control pills, but […]

1:30 PM | How Accurate Is US Patient Outcome Health Data?
A new study concludes that most U.S. clinical registries that collect data on patient outcomes are substandard and lack critical features necessary to render the information they collect useful. A paper in the Journal for Healthcare Quality reveals poor data monitoring and reporting that researchers say are hurting national efforts to study disease, guide patient choice of optimal treatments, formulate rational health policies and track in a meaningful way how well physicians and hospitals […]

1:11 PM | Sudden Oak Death Path Predicted By Citizen Scientists
Citizen science, where the public pitches in to make large-scale analyses of data possible, has successfully predicted the path of a deadly plant disease, Sudden Oak Death, over a six-year period.  The disease has killed millions of oak and tanoak trees in California and Oregon and can infect more than 100 susceptible host plants and can spread from nursery stock to residential landscapes. Starting in 2008, 1,000 volunteers collected leaf samples from trees in metropolitan and […]

1:00 PM | The Murky Ethical Waters Of Marketing To Cancer Patients
By Lisa Marie Potter, Inside Science — A group of doctors clad in white lab coats smiles beneath the heading: "Standing behind your cancer care with nationally recognized excellence."The advertisement was part of the 2009 Dartmouth-Hitchcock health care marketing campaign promoting the Norris Cotton Cancer Center, which has locations in Vermont and New Hampshire. The ad focuses on the facility's reputation and backs up its claims by including its awards of recognition. read more

12:51 PM | Homophobia And Starfish
Recently on Real Clear Science, Ross Pomeroy published an article Why Nothing Can Be Truly ‘Unnatural’, in which he denounces attempts to oppose homosexuality on scientific grounds.  However, after reading it, I am left with the feeling that he is not simply reporting science, but perhaps being a little bit like an old-fashioned nanny telling her charges what is or is not proper.  If so, he will be firing a shot in read more

12:31 PM | Most People Don't Think About The Calories Of Alcohol
Top image: Chandler Collins, CC BY-SAAlcoholic drinks should all carry calorie counts according to a leading UK public health doctor writing in the BMJ today, because of their contribution to obesity. Fiona Sim, Chair of the UK Royal Society for Public Health, writes that while adults who drink may be getting as much as 10% of their daily calories from alcohol, most people are unaware drinking contributes to their energy intake. read more

11:00 AM | What’s the harm? An Australian child dies while undergoing a particularly cruel form of quackery
A common criticism aimed at those of us who are highly critical of various alternative medicine treatments and, in particular, of the “integration” of such treatments into conventional medical treatment is: What’s the harm? What, they ask, is the harm of homeopathy, acupuncture, iridology, or traditional Chinese medicine? They argue that it’s pretty much harmless,…

8:45 AM | Of Vikings, Ships and Combs
What I loved the most about Oslo was the Viking Ship Museum. I had never seen a Viking ship in real life. They are absolutely amazing.I was impressed by their size, but what I found truly interesting was that the Vikings buried their dead in those ships. I cannot imagine how it must have been to inter such enormous things. The dead were buried together with utensils and jewellery in the case of women, tools and weapons in the case of men. There were also remains of dogs and horses, as well as […]

8:00 AM | 5 things science taught us about diets this year
Well, it’s five months into 2015 and for some of us, that means coming to terms with not meeting our New Year’s Resolutions when it comes dieting. With obesity and diabetes on the rise, more and more science is directed at why we do (and don’t) lose weight. Here is what 2015 has taught us so far about weight management. 1. There may actually be an exercise pill. A newly discovered hormone can prevent obesity and insulin resistance in mice... Read more

8:00 AM | What I Got: Three Gifts from the Recovery Ward
1. The Abscess Probably, when I first heard the doctor say to the patient, “The operating rooms are all booked until late tonight so we can just lance it right here, bedside,” that would have been the right time for me to make a little noise. That would have been an appropriate moment to peel […]

El color violeta no suele ser la única particularidad de este inusual anfibio. Su apariencia, lejos está de lo que solemos tener en mente para una rana: nariz pequeña, ojos diminutos y cuerpo robusto también la diferencian de las demás especies conocidas. Estamos hablando de la rana Nasikabatrachus sahyadrensis, una especie de anfibio anuro (los adultos no tienen cola) que habita las montañas occidentales de la India. Un aspecto único y peculiar […]

6:20 AM | This Beetle Sprays Boiling Toxins At Its Predators (Video)
When it comes to defense mechanisms, the bombardier beetle is on a level of its own. These unique beetles have the ability to synthesize and heat a toxic spray within their bodies — when a predator gets too close, the bombardier hits them with a scorching blast of poison. In a study published in the May issue of the journal Science, a team of researchers used a high-speed X-ray camera to capture the process like never before. The video, shot at 2,000 frames per

3:30 AM | SIRT1 Discovery May Lead To New Treatment For MS
Scientists have discovered a way to prevent the development of multiple sclerosis in mice. Using a drug that blocks the production of a certain type of immune cell linked to inflammation and autoimmunity, the researchers successfully protected against the onset of MS in an animal model of the disease.  In the immune system, two kinds of T cells strike a delicate balance--T helper cells (Th17) activate the immune system, protecting against infections and cancers, while regulatory T cells […]
