You Don't Know GMOs One of the biggest challenges currently facing humanity is how to feed the world’s growing population, which is expected to surpass 9 billion people in just 30 years (there are about 7.5 billion people now). Hunger is a complex problem with a lot of variables, but producing more food is certainly an important part of the solution. The UN’s Food and Agriculture Organization predicts that we will have to increase agricultural productivity by at least 60 percent by 2050 if we want to keep up with population growth. And we’ll have to do that against the backdrop of climate change, which presents a whole range of new obstacles. A potential solution is to improve our crops using genetic engineering. Increasing yield There is already some evidence that planting GM crops increases yield. More recently, genetic engineers have improved yield by tinkering with the process of photosynthesis. Decreasing disease Another crucial part of feeding the world is fighting disease.

The Great GMO Corn Experiment – Food Science Institute Some people who have less information about biotechnology have asserted that animals won’t touch or eat GMO corn, and only non genetically modified corn. This is pretty unlikely on the face of it, since farm animals have been feed GM corn for nearly 20 years with zero problems. In addition, GM corn is identical in smell, taste and nutrition. We carried out an early experiment in 2013 to illustrate that this is not the case, finding the squirrels and chipmunks had no such preferences. The non-profit organization Biofortified has undertaken a very large controlled Citizen Science experiment of the same kind, but using corn isolines. Then volunteers were recruited on line to order the corn kits and see how wild animals like them. We did our first experiment this weekend, and found that the squirrels (and maybe 1 chipmunk) ate all of the corn starting with the ear with looser kernels, but eventually ate all of both of them. This is a fun experiment for you to try, too. Like this:
Food for thought... a guide to eating with a clear conscience | Life and style Tuna Environment All commercially fished species of tuna (above) are endangered. Southern bluefin are critically endangered. Tuna fishing, especially for yellowfin with nets, still commonly results in the death of dolphins. Line-caught tuna is preferable but the Marine Conservation Society puts tuna on its top 20 list of fish to avoid because of overfishing and damage to marine habitats. Health Uncontaminated fish oils help,prevent heart disease. Social impact As stocks in the ocean dwindle, tuna are being increasingly sea-farmed in in the Mediterranean and Pacific. Animal health Farming of migratory fish is condemned by welfare groups such as Compassion in World Farming as cruel and liable to encourage disease and parasites. Verdict Avoid all species except skipjack, and make sure it is dolphin-friendly. Swordfish Environment Fishing for swordfish is threatening the future of leatherback turtles (bottom), which managed to survive the extinction of the dinosaurs 65m years ago. Salmon Prawns

Risks and Precautions of Genetically Modified Organisms Commercial potential of biotechnology is immense since the scope of its activity covers the entire spectrum of human life. The most potent biotechnological approach is the transfer of specifically constructed gene assemblies through various techniques. However, this deliberate modification and the resulting entities thereof have become the bone of contention all over the world. Benefits aside, genetically modified organisms (GMOs) have always been considered a threat to environment and human health. 1. Modern biotechnology has allowed the movement of genetic material across unrelated species, something impossible with the traditional breeding methods. Environmental applications of microorganisms are wide and varied, ranging from bioremediation, biopesticides, nitrogen fixation, plant growth promoter, to biocontrol of plant diseases, and other such agricultural practices. Each gene may control several different traits in a single organism. 3. Risk is ubiquitous and unavoidable. 3.1. 4.
The moons of Mars explained Jöjjön egy rövid asztro lecke - természetesen angolul :) Mars has two moons, Phobos and Deimos. They are really tiny. How tiny? Compared to Mars or our own moon, pretty tiny. Although tiny is a matter of opinion. Smaller Deimos on the other hand is slowly escaping Mars. source: Kurzesagt - In a Nutshell Answer the questions. 1) What is the estimated size of the moons of Mars? 2) Why are the moons of Mars not spherical in shape? 3) How did the moons get to Mars’s orbit? 4) What will happen to Phobos in 50-100 million years? 5) Why will Mars end up being ‘lonely’?

What Should We Know About Foreign Genes In Our Food? Bacteria on bean leaf. In a recent email exchange about the merits of mandatory “GMO labeling,” I was asked this question: “Why shouldn’t we be able to know what foreign genes are in our food?” It seems like a reasonable question to most people. What some people find “creepy” about the idea of “GMO crops” is that they contain genes from organisms other than the crop itself – hence the emotive term, foreign genes. Plant Surface Dwellers Above Ground The surfaces of all plants, including those used for food, support a rich and diverse community of micro-organisms. Plant Surface Dwellers Below Ground Root vegetables are covered with microbes that contain 'foreign' genes. There are also richly diverse communities of microbes that live in association with below ground portions of plants (roots, tubers…). Microbes and Their Genes Inside of Plants The inside of a plant is also far from sterile. Would You Like Any Viruses With Your Bacteria? But Isn’t That Different? Yes and no.
For the First Time, a Robot Passed a Medical Licensing Exam In Brief Chinese AI-powered robot Xiaoyi took the country's medical licensing examinations and passed, according to local reports. Xiaoyi is just one example of how much China is keen on using AI to make a number of industries more efficient. A Robot Medical Professional Experts generally agree that, before we might consider artificial intelligence (AI) to be truly intelligent —that is, on a level on par with human cognition— AI agents have to pass a number of tests. Xiaoyi, an AI-powered robot in China, for example, has recently taken the national medical licensing examination and passed, making it the first robot to have done so. This robot, developed by leading Chinese AI company iFlytek Co., Ltd., has been designed to capture and analyze patient information. Local newspaper China Daily notes that this is all part of the country’s push for more AI integration in a number of industries, including healthcare and consumer electronics.

Michael Bond, beloved author of Paddington Bear has died Michael Bond, CBE, the creator of Paddington, has died at home at the age of 91, following a short illness. Bond, who published his first book, A Bear Called Paddington, in 1958, went on to write more than 200 books for children. More than 35 million Paddington books have been sold around the world to date. Bond's latest Paddington novel, Paddington’s Finest Hour, was published in April 2017, with a second Hollywood film based on the books due out later this year. Ann-Janine Murtagh, executive publisher at HarperCollins children’s books said: “I feel privileged to have been Michael Bond’s publisher – he was a true gentleman, a bon viveur, the most entertaining company and the most enchanting of writers. He will be forever remembered for his creation of the iconic Paddington, with his duffle coat and wellington boots, which touched my own heart as a child and will live on in the hearts of future generations.

Genetic Engineering of Food and the Failure of Science – Part 1 Abstract A major conflict has developed in science and society between promoters and opponents of transgenic foods. Food, feed, and fiber products derived from transgenic agricultural crops are presented here as a different case from bacterial, industrial, and pharmaceutical crop transgenics and should be parsed from the larger transgenics industry for comprehensive re-evaluation and market roll-back. Reviewed is the development of the crop transgenics industry; the early influence of the biotechnology industry over the US federal regulatory agencies in the context of the development of minimal regulation; the basic technology of plant transgenics; the main transgenic crops, traits, and producing countries; consumer resistance to transgenic foods; industry problems with shrinking investments; the worldwide promotion of transgenic crops; and ecological issues of transgenic crops.

Jogos de realidade virtual são uma forma menos chata para se exercitar A VirZoom, uma empresa focada em exercícios físicos e realidade virtual, quer te tirar do sofá e colocar em dispositivo para queimar caloria real, mas usando realidade virtual. A startup baseada em Massachussetts está vendendo uma nova série de bicicletas ergométricas que sincronizam com headsets VR para colocar os jogadores em cenários enquanto eles pedalam. Se exercitar é importante, mas olha só que esquisito — desnecessário dizer que isso lembra certo episódio de uma série britânica disponível em uma plataforma de streaming de vídeo. • Esteira inteligente de US$ 4 mil quer ser seu personal trainer à distância Essas bicicletas ergométricas são uma alternativa para bicicletas inteligentes como a Peloton. Enquanto você se exercita com as bicicletas VirZoom, há dois cenários acontecendo simultaneamente. De acordo com o site da VirZOOM, os games são compatíveis com a maioria dos headsets como Samsung Gear, Vive, Oculus e PSVR, mas isso também é um problema. [TechCrunch]
