In Interstellar’s near-ish future, our climate has failed catastrophically, crops die in vast blights and America is a barely-habitable dustbowl. Little education beyond farming methods is tolerated and students are taught that the Apollo landings were Cold War propaganda hoaxes.-->
What will McDonald’s do?
The U.S. Department of Agriculture on Friday cleared a genetically engineered potato with two innovations that help both consumers and producers: The Simplot Innate potato resists bruising, which makes it more appealing to consumers (even though bruising generally does not impact the quality of the starchy vegetable); and it’s been modified to produce less of the chemical acrylamide when fried.
Acrylamide has been linked to cancer in rats although there is no clear evidence that it poses harm to humans.
This is a commonly used argument, indeed often taken for granted. We can simulate physics on a computer. So what is to stop us eventually simulating your whole body including your brain? And if so, is it not just a matter of time, and increasing computer power before we have exact simulations of humans as computer programs? Programs whose behaviour is indistinguishable from humans?
This is a staple of many science fiction stories of course. But some logicians, philosophers and physicists think there are flaws in this argument.
We know the laws of physics are incomplete. Could there be physical processes which for some reason are impossible to simulate using a computer program? And could processes like that go on in a human being?-->
In the NFL, teams share revenue from national television contracts and to sell local tickets, if a team has not sold at least to a specific threshold, the game is blacked out locally. If enough people are attending, the game is shown to fans in the region
That appeals to 'hometown' fans. One satellite network shows all games to its package subscribers but otherwise fans are only going to see their local team. If they don't have one, they see something nearby. It is a rule and there is no choice.
In the modern mobile population, that may not be a wise strategy. Fans no longer live within an hour of where they grew up and a new paper finds that choosing to broadcast the local team isn't always the smartest ratings decision. Writing in

Let’s talk about gastrulation. For those unfamiliar with the term, it’s not as disgusting as it sounds. Gastrulation is a process in early embryonic development which leads to the generation of the three germ-layer tissues- ectoderm, endoderm, and mesoderm- from which all other tissue-types in the body are erived.
The early (amniote) embryo coverts from a bilaminar structure of epithelial tissue plus and extra-embryonic layer, to a trilamiarone. A second function of gastrulation is that it defines the anterior-posterior body axis for the first time. In other words, it begins to distinguish the head end of the embryo from the tail end- this is pretty important if you want all your bits and pieces in the right place later on!

Scientists working on an experiment at the SLAC National Accelerator Laboratory in the US have taken a step forward in developing a technology which could significantly reduce the size of particle accelerators. The technology is able to accelerate particles more rapidly than conventional accelerators at a much smaller size.-->

Will the medicines you take make their way back into your food? They might, especially of you take your cue from an old Yorkshire song which deals with human recycling in the food chain, via worms and ducks. Now, research  from the university of York (where else?) has studied one step of this process in detail.

There are a few things you might need for an experiment involving beagles and the side effects of contraceptive pills. Animal research ethics aside, beagles might be a good start.-->
Instead our poor sister world quickly spiraled into a greenhouse effect that erased its oceans and drove all the water away, leaving a desert planet, coated with dense clouds of sulfuric acid and carbon dioxide.-->
What is the best way to learn a dance sequence?
Professional dancers make it look easy. A choreographer rattles off a long list of moves, kicks and turns and the dancers somehow remember it all. But what about the rest of us who will be hitting the club this weekend?
Researchers from Bielefeld University and the Palucca University of Dance in Dresden are here to help. They researched whether dancers learn a dance sequence better by seeing or by listening, that is, if a dance instructor first demonstrates the sequence, or if he or she first gives a spoken explanation.
An experiment with 42 people under functional magnetic resonance imaging (fMRI) found that if people see pictures of others being loved and cared for, it subsequently reduces
the brain's threat monitor, the amygdala,
response to threats.
This occurred even if the person was not paying attention to the content of the first pictures.
The study in Social, Cognitive and Affective Neuroscience, suggests that being reminded of being loved and cared for dampens the threat response and may allow more effective functioning during, and activation of soothing resources after, stressful situations. This was particularly true for more anxious individuals.
