Bee Brains May Be the Model For the Next Evolutionary Leap in Camera Technology. The beleaguered honey bee is normally championed for its vital powers of pollination but a new study shows that we could soon be thanking them for inspiring more accurate color imaging in digital photography.
Here are my findings from my Whole 30, what I learned and what I'm going to do about it.

It’s no secret that bees have been having a really rough time: Just yesterday, the rusty- patched. Their findings call into question previous assumptions about bees’ perception and they claim that this research could be integrated into cameras to produce a better representation of natural light. In the past, scientists have questioned how it is that a honey bee can recognize the same colors on a flower that it has already visited, even though the ambient light is constantly changing. The accepted solution was that like humans, bees have the capacity for chromatic adaptation. Even if a red object is illuminated by green light, it is still understood to be red.
A theorem called the Von Kries transform gave us a mathematical basis for this idea and it was applied to camera technology to maintain color constancy. If you use a crappy digital camera, colors will look unnatural. But a camera with high- quality sensors and white balance options gives us an image that’s closer to what we perceive with our own eyes.

What this new research suggests is that bees have a different way of processing colors than we previously believed. Bees have two main compound eyes that directly observe the flowers they’re targeting. But on top of their head, they have three ocelli pointed at the sky. Each ocelli has two color receptors that sense ambient light.
In a press release, lead author Dr. Jair Garcia explains: Physics suggests the ocelli sensing of the colour of light could allow a brain to discount the naturally coloured illumination which would otherwise confuse colour perception. But for this to be true the information from the ocelli would have to be integrated with colours seen by the compound eyes. The neural tracings of the ocelli were mapped and it was found that the neural projection was being directed to the color processing areas of the bee’s brain.
The scientists reasoned that parallel visual pathways were feeding into the higher- order visual processing centers of the bee’s brain. When mathematical models of their hypothesis were compared to observed behavior, they concluded that they were correct. Adrian Dyer, one of the coordinators of the research, says, “this discovery on color constancy can be implemented into imaging systems to enable accurate color interpretation.” High hopes are had for an integration of these computational models into drones, cameras, and robots in order to create better color constancy in outdoor settings. Now that killer drones could be improved thanks to the honey bee, can we get some more government support for saving these guys?
List of diets - Wikipedia. An individual's diet is the sum of food and drink that he or she habitually consumes. Dieting is the practice of attempting to achieve or maintain a certain weight through diet. Some people follow unhealthy diets through habit, rather than through a conscious choice to eat unhealthily. Terms applied to such eating habits include .
Many diets are considered by clinicians to pose significant health risks and minimal long- term benefit. This is particularly true of . Vegetarians also avoid food containing by- products of animal slaughter, such as animal- derived rennet and gelatin. In addition to foods permissible in a vegetarian diet, kangaroo meat is also consumed. Under some definitions a plant- based diet is fully vegetarian; under others it is possible to follow a plant- based diet whilst occasionally consuming meat.
Many weight loss diets are considered by some to entail varying degrees of health risk, and some are not widely considered to be effective. This is especially true of . Where this is the case, it is noted in that diet's entry. Low- calorie diets. The book suggests that the key to reaching and maintaining the desired weight is understanding and carefully monitoring calories consumed and used. Nutrisystem distributes low- calorie meals, with specific ratios of fats, proteins and carbohydrates. Such diets are normally followed under the supervision of a doctor.
It starts with two steps intended to facilitate short term weight loss, followed by two steps intended to consolidate these losses and return to a more balanced long- term diet. It’s learning to choose the right carbs and the right fats.
Mc. Dougall draws on historical observation of how many civilizations around the world throughout time have thrived on starch foods. Crash diets. They describe diet plans which involve making extreme, rapid changes to food consumption, but are also used as disparaging terms for common eating habits which are considered unhealthy. Both types of diet are often considered to pose health risks. Where this is the case, it will be noted in that diet's entry. Beverly Hills Diet: An extreme diet which has only fruits in the first days, gradually increasing the selection of foods up to the sixth week.
Considered a fad diet. Only apples are consumed in the first two days, cheese in the following two days, chicken on days five and six, and salad for the final two days. Despite what the name suggests, the diet is not followed by Israel Defense Forces. It is considered a fad diet.
Made famous by former obese student Jared Fogle, who lost 2. Subway sandwiches as part of an effort to lose weight. Examples include meat, white bread, milk and puddings.
Examples include restricting food consumption to foods without colorings or preservatives, taking supplements, or drinking large amounts of water. The latter practice in particular has drawn criticism, as drinking significantly more water than recommended levels can cause hyponatremia.
The health implications of such diets are disputed. The opposite of halal is haraam, food that is Islamically Impermissible. Haraam substances include alcohol, pork, and any meat from an animal which was not killed through the Islamic method of ritual slaughter (Dhabiha). One principle is that natural foods should be consumed. Some Rastafarians interpret I- tal to advocate vegetarianism or veganism. Some foods and food combinations are non- Kosher, and failure to prepare food in accordance with Kashrut can make otherwise permissible foods non- Kosher. About half of Adventists are lacto- ovo- vegetarians.
Dietary advice includes (1) wholesome plants . There are also dietary patterns that might be recommended, prescribed or administered by medical professionals for people with specific medical needs. Colon cancer diet: Calcium, milk and garlic are thought to help prevent colon cancer. Red meat and processed meat may increase risk. There is considerable disagreement in the scientific community as to what sort of diet is best for people with diabetes.
Promoted by the US Department of Health and Human Services, a United States government organisation. It is a medical treatment for gluten- related disorders, which include coeliac disease, non- celiac gluten sensitivity, gluten ataxia, dermatitis herpetiformis and wheat allergy. The healthy kidney diet restricts large amounts of protein which are hard for the kidney to break down but especially limits: potassium and phosphorus- rich foods and beverages. Liquids are often restricted as well—not forbidden, just less of. It is used as a medical treatment for refractory epilepsy.
May be administered by clinicians for medical reasons, such as after a gastric bypass. It is promoted as a way of reducing the symptoms of irritable bowel syndrome (IBS), Crohn's disease, ulcerative colitis, coeliac disease, and autism. For instance, some weight control diets suggest that proteins and carbohydrates should not be consumed in the same meal. It was developed by Max Gerson, who claimed the therapy could cure cancer and chronic, degenerative diseases. These claims have not been scientifically proven, and the American Cancer Society claims that elements of the therapy have caused serious illness and death.
Developed by Sylvester Graham in the 1. Divides foods into separate groups, and suggests that proteins and carbohydrates should not be consumed in the same meal. Not to be confused with low- carb diets, where the intention is to lose weight by restricting carbohydrates.
High residue diet: A diet in which high quantities of dietary fiber are consumed. High- fiber foods include certain fruits, vegetables, nuts and grains. It includes weight counselling among other elements. The dietary aspect involves the consumption of pre- packaged food produced by the company. Common components include grains, beans and vegetables. One of the more distinct features is that olive oil is used as the primary source of fat.
The basis for this claim is disputed. Its composition varies between institutions and states, but as a replacement for standard food, it is intended to provide inmates with all their dietary needs. Pritikin Program for Diet and Exercise: A diet which focusses on the consumption of unprocessed food. Raw foodism: A diet which centres on the consumption of uncooked and unprocessed food. Often associated with a vegetarian diet. Its slogan is . Intermittent fasting consisting of a fasting/feeding cycle with 1 meal per day, ideally at night.
