[quick news] November 20, 2018 "weight loss pen" may be the most failed one on your way to weight loss

"Weight loss pen" may be the most failed one on your way to weight loss Recently, the micro business circle started to sell "weight loss pen" The "weight-loss pen" looks like a ballpoint pen, which is actually injected with a needle in the abdomen, thigh or upper arm Its typical representative is saxenda from South Korea According to reports, "weight-loss pen" needs a doctor's prescription to buy in South Korea, but it has become a "magic weapon" for weight-loss that "does not walk the stomach, does not hurt the body, is safe and has no side effects" applicable to anyone in the micro business circle in China It can be seen from the instructions that the main ingredient of "weight loss pen" is lilalutide, a hormone similar to GLP-1, which is used to treat diabetes It was listed in China in 2011 In clinical trials, the most common side effects of saxenda are nausea, diarrhea, constipation, vomiting, hypoglycemia and loss of appetite In addition, referring to foreign reports on saxenda, users are likely to face more serious side effects, including pancreatitis, gallbladder disease, renal dysfunction and suicidal tendencies Http://digitalpaper.stdaily.com/http_ HTM? Div = - 1 Researchers at the Brookhaven National Laboratory of the U.S Department of energy used ultra bright X-rays to produce a high-resolution three-dimensional chemical image of a single bacterium This is an imaging technique called X-ray fluorescence microscopy (XRF), which can be used as an effective way to generate three-dimensional images of small biological samples The results were published in the latest issue of scientific reports Lisa Miller, a scientist at national synchrotron light source II (nsls-ii), said it was the first time that the resolution of bacterial imaging was raised to the level of cell membrane by using nanometer XRF Imaging cells at the membrane level is essential for understanding the role of cells in various diseases and developing advanced medical treatment methods Https:// A = 213105 "kg" and other four basic units were redefined on November 16 The 26th International metrology Conference (CGPM) passed the resolution on "amending the international system of units" by voting of all Member States According to the resolution, the four basic units of the international system of units - kilogram, ampere, Kelvin and mole - are respectively defined by Planck constant, basic charge constant, Boltzmann constant and Avogadro constant The resolution will enter into force on the next international measurement day, May 20, 2019 It is reported that the international system of units is a globally recognized measurement system, including seven basic units, namely, the unit of length "m", the unit of mass "kg", the unit of time "s", the unit of current intensity "a", the unit of thermodynamics and temperature "Kelvin", the unit of measure of substance "mole" and the unit of luminous intensity "candela" Http://news.scienceet.cn/sbhtmlnews/2018/11/341035.shtm Jaguar v2x technology can avoid always encountering red lights Jaguar, the British car manufacturer, has developed the glosa system, which uses vehicle infrastructure (v2x) technology to communicate with traffic lights and collect the time information of the change of the lights When a driver approaches an intersection, glosa tells the driver how fast he needs to drive to avoid a red light The system can not only avoid people waiting too much time for red lights on the way to work, but also help to reduce traffic accidents and road congestion Https:// walking backwards can enhance short-term memory A foreign study found that walking backwards can enhance short-term memory more than standing or walking forwards After 114 volunteers watched a video, participants were divided into two groups One group was asked to walk 30 feet (10 meters) forward or backward, and the other group was asked to stay still The researchers then asked them 20 questions about the events in the video, and found that on average, the reverse walkers answered two more correct answers than the forward walkers and the standers In addition, experts from the University of rohampton in the UK found a similar phenomenon in the experiment Although the specific reasons are not clear at present, the experimental results may provide a new way for people to improve their memory https://
