Microbes, not food restriction, could be the key to our most effective treatment for obesity. Gastric bypass surgery is the most effective way for those with morbid obesity to lose weight, but new research has confirmed that there could be more to the procedure's success than just limiting food intake.
It seems the bypass also swaps the ecosystem of microbes in the digestive system for one that increases weight-loss, posing a potential way to achieve bypass's benefits without its risks. Best of all, this new assortment of gut bugs sticks around, helping patients lose weight long after the surgery. In 2008, researchers from Arizona State University found the types of bacteria in the digestive systems of patients after they'd had a form of bariatric (weight-loss) surgery called a Roux-en-Y gastric bypass had changed dramatically, leading them to wonder if these new microbes might be at least partially responsible for ongoing weight loss.
With a tiny sample size of just three study groups containing three individuals each, it was hard to draw any solid conclusions. Scientists turn mammalian cells into complex biocomputers. Computer hardware is getting a softer side.
A research team has come up with a way of genetically engineering the DNA of mammalian cells to carry out complex computations, in effect turning the cells into biocomputers. The group hasn’t put those modified cells to work in useful ways yet, but down the road researchers hope the new programming techniques will help improve everything from cancer therapy to on-demand tissues that can replace worn-out body parts. Engineering cells to function like minicomputers isn’t new. As part of the growing field of synthetic biology, research teams around the globe have been manipulating DNA for years to make cells perform simple actions like lighting up when oxygen levels drop. To date, most such experiments have been done in Escherichia coli and other bacteria, because their genes are relatively easy to manipulate.
Watching plants grow has never been this exciting. It’s hard to take a picture of something that’s always moving—just ask anyone who’s had to photograph a child.
Now, one team of researchers has solved the problem on a tiny scale, with a program that lets microscopes automatically track objects invisible to the human eye. Normally, recording something like a growing plant root would mean days of constant adjustments to a microscope. But with their program, researchers were able to watch the cells in root tips of plants (Arabidopsis thaliana) growing and splitting in 3D over the course of days, they report this month on the preprint server bioRxiv. That required some special equipment: a microscope that uses lasers and fluorescent lights to piece together 3D images, a special lighting system to keep the plants healthy during their longer-than-usual time in the spotlight, and a microscope setup flipped entirely on its side so the plants could grow upright instead of growing horizontally along a slide. Watching plants grow has never been this exciting. This video perfectly explains why CRISPR really will change the world forever. 15 myths about a healthy diet you need to stop believing.
Nowadays there are so many discussions about healthy diets, and there are a lot of different opinions about what to eat, when to eat, and how much to eat.
Some recommendations sound suspicious, and so we start doubting their truth. We at Bright Side decided to do our research and dispel popular myths about healthy eating. Adapted from: ’Healthy Weight Loss,’ ’Health’. This 12-year-old just trolled anti-vaxxers in the most brilliant way. It's usually not a good start to the day when you log into Facebook and see a video called, "Vaccines DO cause autism" going viral.
But in this case, 12-year-old Marco Arturo has used the sensationalist headline to troll anti-vaxxers in the most spectacular fashion. Want evidence that vaccines cause autism?

Here's what 200 calories look like for different foods. Your peanut butter's nutrition label — which states that 2 tablespoons = 188 calories — gives you a general idea of how much you're consuming, but you might put down the spoon altogether when you see what that looks like next to 200 calories of celery, carrots or apples.
(Cheese lovers, be warned: What you are about to see may be traumatic.) WiseGeek created a brilliant series of photos capturing exactly what 200 calories looks like among 71 different foods (see the full collection here) and sorted them from low- to high-calorie density. Why did they choose 200 calories? You try fitting 500 calories of celery on a plate! The creative minds behind this project specifically chose 200 calories because they wanted to provide tangible volumes for the entire range of items.

That Stinky Cheese Is a Result of Evolutionary Overdrive. Photo Like many biologists, Ricardo C.
Rodríguez de la Vega searches the world for new species. But while other scientists venture into the depths of the ocean or the heart of the jungle, Dr. Rodríguez de la Vega and his colleagues visit cheese shops. “Every time we’re traveling internationally for a conference or something, we go specifically to the local cheese shop and say, ‘Give me the wildest blue cheese you have,’ ” said Dr. The cheese they buy is alive with fungi; indeed, many cheeses require a particular species of mold to properly ripen. Man walks again after years of paralysis. The ability to walk has been restored following a spinal cord injury, using one's own brain power, according to research published in the open access Journal of NeuroEngineering and Rehabilitation.
The preliminary proof-of-concept study shows that it is possible to use direct brain control to get a person's legs to walk again. New findings rock long-held assumptions about ancient mass extinction. New evidence gathered from the Karoo Basin in South Africa sheds light on a catastrophic extinction event that occurred more than 250 million years ago and wiped out more than 90 percent of life in Earth's oceans and about 70 percent of animal species on land.
In research to be presented Nov. 4 at the annual meeting of the Geological Society of America and published in the October issue of the journal Geology, a University of Texas at Dallas geologist and his colleagues describe new findings that challenge the currently accepted model of the "Great Dying" and how it affected land animals. That event occurred at the end of the Permian geologic period. The new evidence derives from a key volcanic ash deposit that the team discovered in rock layers, or strata, that were reported to chronicle the mass extinction. Jawbone in Rock May Clear Up a Mammal Family Mystery. Predator Prey. Predator/Prey (also known as the Survival Game or the Game of Life) This is a complicated game but very worthwhile for teaching the girls the basics of ecology and the food chain. In the introduction to the game, you should talk about the relationship between herbivorous (plant-eating), omnivorous (everything-eating) and carnivorous (meat-eating) animals.
You should also talk about some possible strategies that the three different types of animals use to survive in nature. More will become clear as I describe the basic set-up below. Materials: 30 "Herbivore" life-rings (described below), 10 "Omnivore" life-rings, 5 "Carnivore" life-rings, 5 water stations, 5 food stations, 45 file cards, a whistle, a water gun, brown, green and red face paint. Cell Function: Meiosis. What are the big ideas here? There are two cell divisions. Mitosis has one division and meiosis has two divisions. You still have to remember PMATI, but now you do it twice. You also need to remember that four cells are created where there was originally one. That's four (4) cells with half of the amount of DNA needed by a cell. ScienceAlert. ScienceAlert.

The LIFE Project aims to bridge the gap between nature and science, and is realized through the integration of photography with the performing arts and the world of life and earth sciences, in collaboration with partners and institutions around the world. The LIFE Project includes a multimedia orchestral performance, a traveling exhibition, and a large-format photographic book. Public outreach includes an ongoing series of appearances by Frans Lanting at venues across the United States and Europe, including the TED Conference, Stanford University, the National Geographic Society, the Long Now Foundation, and many others.
