New Finger Device Reads Books To The Blind Researchers from the MIT Media Lab have developed a device shaped like a giant ring that can read to people who are visually impaired. They call this 3-D printed prototype, FingerReader. After slipping the device on, the user just runs an index finger below the printed text in a magazine, on a business card, or on a menu, for example. A small camera scans the words and the device reads them out loud in real time. Details about FingerReader can be found in this paper [pdf], and here’s a video of how it works: FingerReader is a lot like “reading with the tip of your finger,” MIT’s Pattie Maes explains to AP. According to the World Health Organization, 285 million people are visually impaired, and of them, 39 million are blind.
Redonner la vue aux aveugles : des chercheurs ont trouvé un moyen de faire repousser la cornée SANTÉ - C'est une découverte scientifique importante. Des chercheurs américains ont trouvé le moyen de faire repousser, à partir de cellules souches, la cornée, cette membrane du globe oculaire qui permet le passage de la lumière dans l'œil. De quoi redonner espoir à certains aveugles, notamment ceux victimes de brûlures, de lésions chimiques et de certaines maladies oculaires. Publiée cette semaine dans la revue scientifique Nature, cette recherche a été menée conjointement par des scientifiques d'Harvard, du Boston Children’s Hospital, du Brigham and Women’s Hospital, et du VA Boston Healthcare System. "Les cellules souches limbiques résident dans la limbe de l’œil et aident à maintenir et régénérer les tissus de la cornée. Des cellules difficiles à repérer Or, ces cellules souches sont difficiles à repérer. "Des anticorps ont permis de détecter ces molécules ABCB5, facilitant l’identification de cellules souches dans les tissus cornéens de personnes décédées.
8 Vegetables You Can Regrow Forever and Ever These 8 vegetables you can reuse even after you’re done chopping them up. Bet you didn’t know you could regrow your celery just by sticking the butt-end into a glass of water! It does require some time though but the benefits riding on the project are many. It saves money and you don’t even need a garden. Use fresh scraps only. 1. Regrow them using their discarded roots. 2. Garlic sprouts can be grown from the garlic clove and have a mild flavor from that of garlic. 3. In a well lit area, place the Bok Choy’s root ends in water. 4. Carrot greens can be regrown from carrot tops. 5. Basil cuttings can be used to grow new basil. 6. You can use the leftover celery bottom for this. 7. Romaine lettuce can be grown from the bottom of a lettuce head. 8. If you place the stems of cilantro in a glass of water, they will grow. See something that needs editing? (h/t: unbelievable-facts)
Say No to Nocebo: How Doctors Can Keep Patients' Minds from Making Them Sicker - Inkfish “First, do no harm,” the saying goes, but that might be close to impossible. Just as our expectations can make us feel better, they can also make us feel much worse. This means that how doctors phrase their instructions or introduce new drugs may have a real impact on our health. But some doctors are trying to figure out how they can do less harm by harnessing the surprising power of their words. “In the classical view that is still taught at medical school and in textbooks, drug actions are purely determined by the drug,” says Ulrike Bingel, a neurologist at the University of Duisburg-Essen in Germany. “But that is not true.” The Latin version of “first, do no harm” (for when you want it to sound extra serious) is primum non nocere. For example, Bingel writes in a JAMA Viewpoint, switching from a brand-name drug to a generic version can make people report more side effects—even when the two drugs are chemically identical. Expectations are key to both placebo and nocebo.
Where Does Your Fat Go When You Lose Weight? We talk a lot about dieting and burning off fat, but we actually have a lot of misconceptions about weight loss. Some people think fat is converted into energy or heat—a violation of the law of conservation of mass—while others think that the fat is somehow excreted or even converted to muscle. I was told early on that you can never lose your fat cells (adipose) once you gain them...they just shrink if you work it off. Well, according to Andrew Brown from the University of New South Wales and Australian TV personality (slash former physicist) Ruben Meerman, when you lose weight, you exhale your fat. Their new calculations, based on existing knowledge about biochemistry, were published in the British Medical Journal this week. “There is surprising ignorance and confusion about the metabolic process of weight loss,” Brown says in a news release. So, for this upcoming post-holiday season, should we all just exhale more to shed those extra pounds?
10 Ways the World Will Change by 2025 Teleportation, cures for disease, and no more plastic? It may sound impossible, but Reuters has predicted differently - and all by 2025. By: Amanda Froelich, True Activist. Teleportation, food equality, successful disease treatment – sound too good to be true? After analyzing huge volumes of data regarding the scientific studies and patent applications, the child agency of Reuters created a list of the top 10 innovations that promise to dramatically change the planet by 2025. Credit: Learning-Mind While some of the following may be perceived as debatable (pending the ethics and public acceptance of genetically modified foods, for example), the Intellectual Property and Science Department of the company is optimistic that these ten identified areas will no doubt change the world. 1. Thanks to the advancements made in photovoltaic technology, the photocatalysts, distribution networks, and energy storage batteries, solar energy will become the main source of energy on the planet. 2. 3. 4. 5.
Suspended Animation Human Trials About to Begin With traumatic injuries, timing in treatment can be the difference between life and death. What if surgeons could hit the pause button, giving them precious additional time to treat the wounds? Suspended animation has been featured in a wide array of fictional films, but could it actually work on humans? In Hollywood, suspended animation involves freezing solid (or nearly so), thawing at some point in the future when new medical advances have taken place to treat their conditions. This state of hypothermia can only be sustained by the human body for about two hours. Peter Rhee first tried this technique on 40 pigs in 2000, with the results published in 2006. Due to the extremely time-sensitive and dire nature of the injuries of the test subjects, the FDA has declared that the surgeons will not require informed consent. The team will first use this technique on 10 trauma patients whose injuries would be otherwise fatal.
Why You Should Never Eat Pork There are many religions that specifically forbid the consumption of pork. The meat is considered “unclean” and non-kosher. Is there a reason for this? Is there more to this religious teaching that we should all be aware of? It seems as though the religions that condemn pork consumption are on to something, in fact there are many scientific claims to back this up. Pigs are scavengers by nature, which means that they will eat almost anything, including rotten food, feces, urine, carcasses and even cancerous growths. “Sweating like a pig” yet? According to an investigation by Consumer Reports, 69% of all raw pork samples tested (of about 200 samples) were contaminated with a dangerous bacteria known as Yersinia enteroclitica. Ground pork was more likely to be contaminated than pork chops. According to the report: “We found salmonella, staphylococcus aureus, or listeria monocytogenes, more common causes of foodborne illness, in 3 to 7 percent of samples. As issued by Consumer Reports:
