Forget joysticks, use your torso to pilot drones

Imagine piloting a drone using the movements of your torso only and leaving your head free to look around, much like a bird. EPFL research has just shown that using your torso to pilot flying machines is indeed more immersive — and more effective — than using the long-established joystick. The results are published in today’s issue of PNAS.

“Our aim was to design a control method which would be easy to learn and therefore require less mental focus from the users so that they can focus on more important issues, like search and rescue,” says lead author Jenifer Miehlbradt of EPFL’s Translational Neuroengineering Laboratory led by Bertarelli Foundation Chair Silvestro Micera. “Using your torso really gives you the feeling that you are actually flying. Joysticks, on the other hand, are of simple design but mastering their use to precisely control distant objects can be challenging.”

The scientists wanted to observe how people use their bodies to pilot a flying object, in this case a drone, and determine which movements are most intuitive and natural — approaching the pilot problem from a completely new perspective.

They started by monitoring the body movements of 17 individuals thanks to 19 markers placed all over the upper body as well as their muscular activity. Each participant followed the actions of a virtual drone through simulated landscapes that passed-by as viewed through virtual reality goggles.

Motion patterns emerged and the scientists quickly established torso-related strategies for piloting drones: they found that only 4 markers — located on the torso — were needed to pilot flight simulators and real drones through a circuit of obstacles effectively.

Overall, the scientists compared their torso strategies to joystick control in 39 individuals. They found that torso drone control outperformed joystick control in precision, reliability and with minimal training sessions.

“Data analysis allowed us to develop a very simple and intuitive approach which could also be used with other populations, machines, and operations,” says Micera, also at the Scuola Sant’Anna in Italy in Biomedical Engineering. He adds, “The approach significantly improves the teleoperation of robots with non-human mechanical attributes.”

While the PNAS results provide a truly new and completely immersive piloting strategy with a focus on characterizing the relevant torso parameters, leaving the head, limbs, hands and feet free to perform other actions, their proof-of-concept system still requires body markers and external motion detectors in order to work.

The next steps are to make the torso strategy completely wearable for piloting flying objects. The application range is huge, from flight simulators to piloting drones and even perhaps planes of the future. A garment that implements the torso strategy into drone control without external motion detectors was developed at EPFL based on the PNAS findings.

Apple is a fruit with multifarious uses and health benefits. Whether you like to eat it raw or toss it in salads, custards, puddings, turn it into pies and cakes, or make curries from it – apples never disappoint. They are great to taste in both sweet and savoury dishes and are chock-full of nutrition. They have a number of health benefits, ranging from regulation of blood sugar and cholesterol to helping you keep your weight in check. This is why consuming apples in the right quantity and manner may help you shed those extra kilos. Although a lot of people know about apple cider vinegar and its weight loss benefits, not many people are aware about the other apple drink that may help you lose weight – apple tea. It’s a drink that you can make at home and consume immediately to boost fat burn and effect weight loss.Apple tea is a concoction that is made by boiling apple slices along with black tea leaves and can be spiced with cinnamon and cloves. The tea can be consumed warm or cold and is slightly sweet and flavourful. The drink has a number of health benefits, which make a great weight loss drink.

Here Are Some Health Benefits Of Apple Tea That Make It Great For Weight Loss:

1. Boosts Immunity: Apple tea contains good amounts of vitamin C, which is seeped out into the boiling water when apple slices are dunked in it. A good immune system is crucial for effective weight loss.

2. Fights Cholesterol: The fibre and antioxidant polyphenols present in apple pulp and the skin may help lower the levels of low density lipoprotein (LDL) or bad cholesterol from the blood and, hence, promote fat burn.

3. Boosts Digestion: A healthy digestive system is linked to better weight loss and apple tea may help boost digestion because apples have good amounts of soluble fibre in them. Soluble fibre is also known to be great for weight loss. Apples also have malic acid, which ensures a healthy digestive system.

4. Regulates Blood Sugar: Apples have natural sugars in the form of fructose, as well as antioxidants, which improve metabolic balance and also regulate levels of blood sugar. It prevents any sudden rise or fall in levels of blood sugar, eliminating the need for you to eat more often.

5. Low In Calories: Apples are negative calorie fruits, which simply means they are very low in calories. A standard-sized apple contains about 50 calories per 100 gm of the fruit, according to United States Department of Agriculture. So, whether you prefer eating them or drinking them in form of teas, apples can help you maintain a low-calorie count.

How To Make Apple Tea For Weight Loss

Apple tea is very easy-to-make and is great for consumption in colder climates. For making apple tea, all you need one whole apple, three cups of water, a tablespoon of lemon juice, two teabags and cinnamon stick or cinnamon powder. Put the water in a deep-bottomed pan and add the lemon juice to it. Put the pan on the flame and then dunk the tea bags in it. While you wait for the tea to boil, chop your apple up in small cubes and then add these to the boiling tea. Make sure your fruit is added to the tea, with the skin on. Let the concoction simmer for about five minutes and finally, add your cinnamon stick or powder to it. Strain the tea out into cups and add a natural sweetener of your choice to it.

You will be left with about a cupful of leftover apples from the tea, which you definitely shouldn’t throw out. You can either consume these as is, or you can add them to your fruit custard. The cinnamon in the tea can help detoxify your system and fight inflammation. If you are allergic to apples, then you should obviously not drink this tea. It’s always advisable to consult a certified physician or dietitian before adding this tea to your weight loss diet.

Plastic chemical linked to smaller prefrontal cortex, reduced cognitive ability in rats

Adult rats that had been exposed before birth and during nursing to a mixture of chemicals found in a wide range of consumer products have a smaller medial prefrontal cortex (mPFC) and perform worse on an attention-switching task than rats not exposed to the chemicals early in life. These findings demonstrate a long-term influence of endocrine-disrupting compounds on brain development.

Model for cutting binge drinking in college students

The study also analyzed participants’ overall willingness to initiate and sustain responsible drinking habits or abstinence. Compared to men, women were 38 percent more willing to initiate or try responsible drinking and 49 percent more willing to sustain those habits. Non-white college students were 41 percent more willing to initiate responsible drinking behaviors than whites and 96 percent more willing to sustain those habits.

Better methods improve measurements of recreational water quality

The concentration of enterococci, bacteria that thrive in feces, has long been the federal standard for determining water quality. Researchers have now shown that the greatest influences on that concentration are the quantity of mammalian feces in the water, and the numbers of enterococci that glom onto floating particulate matter.

Daily fasting works for weight loss, finds report on 16:8 diet

Daily fasting is an effective tool to reduce weight and lower blood pressure, according to a new study published by University of Illinois at Chicago researchers in the journal Nutrition and Healthy Aging.

The study is the first to examine the effect of time-restricted eating — a form of fasting that limits food consumption to select hours each day — on weight loss in obese individuals.

To study the effect of this type of diet, researchers worked with 23 obese volunteers who had an average age of 45 and average body mass index, or BMI, of 35.

Between the hours of 10 a.m. and 6 p.m. the dieters could eat any type and quantity of food they desired, but for the remaining 16 hours they could only drink water or calorie-free beverages. The study followed the participants for 12 weeks.

When compared to a matched historical control group from a previous weight loss trial on a different type of fasting, the researchers found that those who followed the time-restricted eating diet consumed fewer calories, lost weight and had improvements in blood pressure. On average, participants consumed about 350 fewer calories, lost about 3 percent of their body weight and saw their systolic blood pressure decreased by about 7 millimeters of mercury (mm Hg), the standard measure of blood pressure. All other measures, including fat mass, insulin resistance and cholesterol, were similar to the control group.

“The take-home message from this study is that there are options for weight loss that do not include calorie counting or eliminating certain foods,” said Krista Varady, associate professor of kinesiology and nutrition in the UIC College of Applied Health Sciences and corresponding author on the study.

While this is the first study to look at the 16:8 diet, named for its 16 hours of fasting and its 8 hours of “feasting,” Varady says that the results align with previous research on other types of intermittent fasting diets.

“The results we saw in this study are similar to the results we’ve seen in other studies on alternate day fasting, another type of diet,” Varady said, “but one of the benefits of the 16:8 diet may be that it is easier for people to maintain. We observed that fewer participants dropped out of this study when compared to studies on other fasting diets.”

Varady says that while the research indicates daily fasting works for weight loss, there have not yet been studies to determine if it works better than other diets, although the researchers observed the weight loss to be slightly less than what has been observed in other intermittent fasting diet studies.

“These preliminary data offer promise for the use of time-restricted feeding as a weight loss technique in obese adults, but longer-term, large-scale randomized controlled trials [are required],” Varady and her colleagues write.

“The 16:8 diet is another tool for weight loss that we now have preliminary scientific evidence to support,” Varady said. “When it comes to weight loss, people need to find what works for them because even small amounts of success can lead to improvements in metabolic health.”

The Centers for Disease Control and Prevention estimates that more than one-third of adults in the U.S. have obesity, which greatly increases the risk of metabolic diseases such as coronary heart disease and Type 2 diabetes, and that obesity is most prevalent among non-Hispanic black individuals and middle-age adults.

Co-authors on the study, which was funded by a University of Illinois Chicago Campus Research Board pilot grant and the National Institutes of Health (R01HL106228, F32DK107157 and T32HL007909), are Kelsey Gabel, Kristin Hoddy, Nicole Haggerty, Jeehee Song, Cynthia Kroeger and John Trepanowski of UIC, and Satchidananda Panda of the Salk Institute for Biological Studies.
