http://www.united-academics.org/magazine/health-medicine/coffees-dirty-secret-like-carcinogens-with-that/

by Elisabeth Buhl Thubron in United Academics

Furans are coffee’s dirty little secret. Although we can thank them for the pleasant aroma and delicious flavour of freshly brewed coffee, furans have been labelled as a possible human carcinogen (cause of cancer) in disguise by food safety agencies. How many are in there
depends on how you like your cup of Joe.... Read more »

The cool car: electric vehicles show possible benefit to combat climate change

by Jonathan Trinastic in Goodnight Earth

Electric vehicles are touted as environmentally friendly, but they actually pollute more than conventional vehicles during manufacturing. However, a new report argues that, because electric vehicles are cooler, they can reduce heat and temperature increases in urban environments, leading to a net reduction in greenhouse gas emissions....

Global Warming Turns Rainforest Leaves into Junk Food

by Elizabeth Preston in Inkfish



Like those breakfast cereals that look healthy on the box but have even more sugar inside than Cocoa Puffs, some rainforest trees engage in false advertising. It's not their fault—it's ours. Climate change has made their leaves less nutritious than they used to be. And the animals who live off of those trees don't exactly have another store to shop at.

Experiments in labs and greenhouses have given scientists mixed answers about what happens to plant tissues in a changing climate. So pr........ Read more »

Komodo Dragons: Their Bite is Worse than Their Bark

by Miss Behavior in The Scorpion and the Frog

By Shelly Sonsalla Komodo Dragon. Image by Arturo de Frias Marques on Wikimedia. Komodo dragons are the world’s largest living lizard and can be found only on select islands in the Indonesian archipelago. These massive lizards can grow to be 10 feet in length and up to 150 pounds! Their natural prey includes wild boars, deer, and water buffalo—animals which may outweigh them by several hundred pounds. So how does a lizard, even such a large one, manage to take down prey so much larger tha........ Read more »

Special microbes make anti-obesity molecule in the gut

by Dr. Jekyll in Lunatic Laboratories

You’ve probably heard of all sorts of diets, paleo, low-fat, low-carb, atkins, but now microbes may just be the next diet craze. Researchers have programmed bacteria to generate a molecule that, through normal metabolism, becomes a hunger-suppressing lipid (fat). Mice that drank water laced with the programmed bacteria ate less, had lower body fat and staved off diabetes — even when fed a high-fat diet — offering a potential weight-loss strategy for humans....

The Palm Tree That Waters and Fertilizes Itself

by Elizabeth Preston in Inkfish



Even the most dismal gardener wouldn't mind taking charge of a plot of Lodoicea maldivica. This palm tree knows how to water itself. It even adds fertilizer. As a result, it rules the forest, turning a bad soil situation into seeds the size of a four-year-old human.

Lodoicea maldivica is commonly called the coco de mer palm. "Commonly" might be the wrong word, though, since the tree grows on exactly two islands in the world, in the Seychelles. It roots itself in soil made from weathered g........ Read more »

How photosynthesis is inspiring solar power research

by GrrlScientist in Maniraptora

SUMMARY: To meet humanity’s growing energy demands, scientists are taking lessons from plants, which perfected the process of capturing the sun’s rays and transforming that into starch. Might scientists be able to adapt the photosynthetic process pioneered by plants and adapt it to meet human demands? ... Read more »

Mercury, autism and mitochondrial dysfunction?

by Paul Whiteley in Questioning Answers

Appreciating that to mention the words 'mercury and autism' in the same sentence can lead to furrowed brows and invoke eye-rolling in some quarters, I don't want to shy away from the results reported by Shannon Rose and colleagues [1] (open-access here) and their suggestion that: "the epidemiological link between environmental mercury exposure and an increased risk of developing autism may be mediated through mitochondrial dysfunction". Further that their result: "support the notion that a subse........ Read more »

You are what you eat

by naturallyspeakingpodcast in Naturally Speaking Podcast

Ecologists have long tried to understand what animals get up to when they’re not being observed. GPS technologies have enabled unprecedented remote-tracking, but some behaviours – such as diet – are a little more tricky to track. In this post James Grecian (@JamesGrecian), a marine ecologist at the Institute, discusses a technique he uses to track the diet of marine seabirds across some of the world’s […]

The food additive that may be promoting obesity and metabolic syndrome

by Dr. Jekyll in Lunatic Laboratories

People say to avoid processed foods, while I don’t agree with that fully, a new study suggests that a common food additive may be causing problems. Emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can alter the gut microbiota composition and localization to induce intestinal inflammation that promotes the development of inflammatory bowel disease and metabolic syndrome....

Move over oil, new pretreatment could cut biofuel costs by 30 percent or more

by Dr. Jekyll in Lunatic Laboratories

Alternative fuels have a few large problems making them horrible options over oil (which is already a horrible choice). However, researchers may have finally eliminated one of those problems, cost. The team has invented a novel pretreatment technology that could cut the cost of biofuels production by about 30 percent or more by dramatically reducing the amount of enzymes needed to breakdown the raw materials that form biofuels....

Getting your tonsils removed: A (sometimes) cure for bedwetting

Kids who snore are more likely to wet the bed than kids who don’t. Strangely enough, the reason may be their too-big tonsils, which can cause the snoring and sleep apnea affecting 1 in 10 kids. In 2013, Michigan scientists … Continue reading →... Read more »

Everyday chemical exposure leads to early menopause

by Dr. Jekyll in Lunatic Laboratories

Seems like everything is killing us these days. Well ladies, you have one more thing that is causing you problems. New research has shown that women whose bodies have high levels of chemicals found in plastics, personal-care products, common household items and the environment experience menopause two to four years earlier than women with lower levels of these chemicals....
