Central Cygnus Skyscape

In cosmic brush strokes of glowing hydrogen gas, this beautiful skyscape unfolds across the plane of our Milky Way Galaxy and the center of the northern constellation Cygnus the Swan. The featured image spans about six degrees. Bright supergiant star Gamma Cygni (Sadr) to the upper left of the image center lies in the foreground of the complex gas and dust clouds and crowded star fields. Left of Gamma Cygni, shaped like two luminous wings divided by a long dark dust lane is IC 1318, whose popular name is understandably the Butterfly Nebula. The more compact, bright nebula at the lower right is NGC 6888, the Crescent Nebula. Some distance estimates for Gamma Cygni place it at around 1,800 light-years while estimates for IC 1318 and NGC 6888 range from 2,000 to 5,000 light-years.

First almost fully-formed human brain grown in lab

An almost fully-formed human brain has been grown in a lab for the first time, claim scientists from Ohio State University. The team behind the feat hope the brain could transform our understanding of neurological disease.

Though not conscious the miniature brain, which resembles that of a five-week-old foetus, could potentially be useful for scientists who want to study the progression of developmental diseases. It could also be used to test drugs for conditions such as Alzheimer’s and Parkinson’s, since the regions they affect are in place during an early stage of brain development.

The brain, which is about the size of a pencil eraser, is engineered from adult human skin cells and is the most complete human brain model yet developed, claimed Rene Anand of Ohio State University, Columbus, who presented the work today at the Military Health System Research Symposium in Fort Lauderdale, Florida.

Previous attempts at growing whole brains have at best achieved mini-organs that resemble those of nine-week-old foetuses, although these “cerebral organoids” were not complete and only contained certain aspects of the brain. “We have grown the entire brain from the get-go,” said Anand.

Anand and his colleagues claim to have reproduced 99% of the brain’s diverse cell types and genes. They say their brain also contains a spinal cord, signalling circuitry and even a retina.

The ethical concerns were non-existent, said Anand. “We don’t have any sensory stimuli entering the brain. This brain is not thinking in any way.”

Anand claims to have created the brain by converting adult skin cells into pluripotent cells: stem cells that can be programmed to become any tissue in the body. These were then grown in a specialised environment that persuaded the stem cells to grow into all the different components of the brain and central nervous system.

According to Anand, it takes about 12 weeks to create a brain that resembles the maturity of a five-week-old foetus. To go further would require a network of blood vessels that the team cannot yet produce. “We’d need an artificial heart to help the brain grow further in development,” said Anand.

Several researchers said it was hard to judge the quality of the work without access to more data, which Anand is keeping under wraps due to a pending patent on the technique. Many were uncomfortable that the team had released information to the press without the science having gone through peer review.

Zameel Cader, a consultant neurologist at the John Radcliffe Hospital, Oxford, said that while the work sounds very exciting, it’s not yet possible to judge its impact. “When someone makes such an extraordinary claim as this, you have to be cautious until they are willing to reveal their data.”

If the team’s claims prove true, the technique could revolutionise personalised medicine. “If you have an inherited disease, for example, you could give us a sample of skin cells, we could make a brain and then ask what’s going on,” said Anand.

You could also test the effect of different environmental toxins on the growing brain, he added. “We can look at the expression of every gene in the human genome at every step of the development process and see how they change with different toxins. Maybe then we’ll be able to say ‘holy cow, this one isn’t good for you.’”

For now, the team say they are focusing on using the brain for military research, to understand the effect of post traumatic stress disorder and traumatic brain injuries.

Leather shoe with a “poulaine” or elongated toe. In the mid-to late-1300s, it was very fashionable to have long, tapering toed shoes, worn by the aristocracy and the fashion-conscious. The longer the toe, the higher the social status. Since they were so difficult to walk, work, or fight in, those with the most leisure time could have the longest poulaines. This particular poulaine comes from London,  the mud along the Thames had preserved it perfectly for 700 years.

August 19th 1883: Chanel born

On this day in 1883, the French fashion designer Coco Chanel was born in Saumur. Born Gabrielle Bonheur Chanel, after the death of her mother she was sent to an orphanage and raised by nuns. As a young woman, Chanel frequently sang in cafes, during which time she acquired the name Coco. Having learned to sew at the orphanage, Chanel opened a hat shop in Paris in 1910, with the financial backing of her wealthy lover. Chanel began making clothes after she made a dress out of an old jersey on a cold day, and people expressed interest in her clothes. By the 1920s, Chanel’s business had expanded, allowing her to launch her first perfume - Chanel No. 5. However, a deal struck with businessmen who helped produce and market the perfume meant Chanel herself only received 10 percent of the profits. Also in the 1920s, she introduced the iconic Chanel suit and the little black dress, which were revolutionary and liberating in their emphasis on comfort over restrictive clothing such as corsets which had defined women’s fashion for decades. Chanel had a tumultuous and well-publicised love life, dating the duke of Westminster and, during the Nazi occupation of Paris, becoming involved with a German military officer. The scandal of her involvement with Nazis, coupled with the company’s financial difficulties after the Depression, led Chanel to retreat from the public eye until the 1950s. Coco Chanel lived long enough to see her career revived and her life be adapted into a Broadway musical starring Katharine Hepburn. Since her death in 1971 aged 87, the company she founded continues to be one of the most iconic names in fashion.

How Coke Is Subtly Blaming You for Obesity

Which is more important for weight loss: diet or exercise? While science has one answer, soda manufacturers have another

For years the message from medical experts to the increasingly hefty American population has been the same—watch what you eat, and exercise. But since everybody eats, but not every person is physically active, the focus has really been more on the former rather than the latter. Diet is an easier target, too, because the biggest culprits are simple to spot: fried favorites, calorie-dense fast food, sugar-sweetened beverages and processed foods that pack a lot of fat-building carbohydrates and sugar. Eat less of these, the white-coat brigade keeps telling us, plus more fruits, vegetables and whole grains, and it’ll be easier to control weight, avoid putting on extra pounds and bypass serious diseases like heart problems and diabetes. The problem is, the messaging hasn’t worked. Obesity rates have continued to climb in recent decades. (While they’ve started to level off, there still aren’t many signs that they are beginning to drop.) So some people are now changing the mantra: instead of focusing on what you put into your body, turn your attention to what you do with the energy, stored up in the form of fat, that you’ve packed away. Worry less about your diet, and get active so you can burn off the unwanted calories you consume to keep your weight in check.

The sugar-sweetened beverage industry has hungrily adopted the message. Facing mounting pressure to improve their products, both when it comes to calories and overall nutrition, they’re eagerly shifting the attention—or blame—from their fare to the American public. It’s not us, they seem to be saying, but you. You’re just not moving enough to burn off all the calories you’re taking in. First, the makers of Coca-Cola, Dr. Pepper, and Pepsi, along with the American Beverage Association, launched Mixify, a campaign that encourages young soda drinkers to “mixify” their balance of sugared drinks and exercise, giving license to indulge more if they’re more active. But the latest soda-backed program is the Global Energy Balance Network, a collaboration of leading medical experts with a mission to urge Americans to focus on finding a better balance between what they eat and what they burn off (which, for the mainly sedentary American population, is about getting more active.) The network is supported by Coca-Cola, though initial invitations to scientists failed to mention that.
