What most people don’t know, that they should, is that practically every food you buy in a store for consumption by humans is genetically modified food. There are no wild seedless watermelons, there’s no wild cows, there’s no long-stem roses growing in the wild …
We have systematically genetically modified all the foods, the vegetables and animals, that we have eaten ever since we cultivated them. It’s called artificial selection. That’s how we genetically modify them. So now that we can do it in a lab, all of a sudden, you’re going to complain?
So we are creating and modifying the biology of the world to serve our needs. I don’t have a problem with that because we’ve been doing that for tens of thousands of years. So, chill out.
Dreadnoughtus: Gigantic, exceptionally complete sauropod dinosaur | ScienceDaily
Scientists have discovered and described a new supermassive dinosaur species with the most complete skeleton ever found of its type. At 85 feet (26 m) long and weighing about 65 tons (59,300 kg) in life, Dreadnoughtus schrani is the largest land animal for which a body mass can be accurately calculated. Its skeleton is exceptionally complete, with over 70 percent of the bones, excluding the head, represented. Because all previously discovered supermassive dinosaurs are known only from relatively fragmentary remains, Dreadnoughtus offers an unprecedented window into the anatomy and biomechanics of the largest animals to ever walk the Earth.
Device Captures Solar Energy, Doesn’t Block View
A team of researchers at Michigan State Univ. has developed a new type of solar concentrator that, when placed over a window, creates solar energy while allowing people to actually see through the window.
It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has a clear surface.

We’ve come to expect impossible, even improbable standards of beauty to populate our magazines and our television shows. It’s another thing entirely to find they’ve invaded our workplace.
SciO might not have the most airtight use case, but I’m sure we’ll think of something.
Any nerd can appreciate the appeal of the “tricorder” device made famous by Kirk, Spock, Scotty, and other characters from Star Trek. Point it at prett…
Wow, their Kickstarter is already $2 million over their original goal of $200k.
Conceptually, bioelectronics is straightforward: Get the nervous system to tell the body to heal itself. But of course it’s not that simple. “What we’re trying to do here is completely novel,” says Pedro Irazoqui, a professor of biomedical engineering at Purdue University, where he’s investigating bioelectronic therapies for epilepsy. Jay Pasricha, a professor of medicine and neurosciences at Johns Hopkins University who studies how nerve signals affect obesity, diabetes and gastrointestinal-motility disorders, among other digestive diseases, says, “What we’re doing today is like the precursor to the Model T.”
Scientists have created a sonic tractor beam. And it’s not simply an amazing proof of concept: This beam pulls with a billion times more force and can tow objects a million times larger than previous schemes for tractor beams. Tractor beams are staples of science fiction, projected from the Death Star in Star Wars and the Enterprise in Star Trek. The term was coined by sci-fi author and chemical engineer E.E. “Doc” Smith in 1931. In reality, scientists have previously succeeded in using light and sound waves to push and pull objects around on the microscopic level. For example, take laser-based optical tweezers, in which light imparts a slight push or pull on an item. Since the forces involved are small, these devices are used for moving things of correspondingly tiny size, including cells. Now acoustical engineers, led by Christine Démoré and Patrick Dahl at the University of Dundee in Scotland, have developed an acoustic tractor beam that can reel in centimeter-size objects.
A new “GPS” for your DNA can track your where your ancestors lived a millennium ago, and much more accurately than previous methods—down to the exact village in some cases. The GPS method stands for Geographic Population Structure, and is a play on words as it helps you find your way home, just not the home you currently live in, explain the researchers behind the method, Ehran Elhaik of Sheffield University and Tatiana Tatarinova of the University of Southern California.
According to their study published this week in Nature, the tool has traced DNA origins with 98 percent accuracy, while previous methods were often off by 700 km, which is a whole different country in some parts of the world. But when researchers applied their GPS-based approach to over 200 Sardinian villagers, they were able to place a quarter of them in their villages of genetic origin, and the rest within 50 km.
The increased accuracy of the new model is based on a simple, if controversial, assumption made by the study authors: that race doesn’t exist.
“The model of races is incorrect and should be dismissed,” Elhaik told me in an email. Up until now, tracing genetic origins assumed that people could be typified as a mix of two to three defined races, presupposing a homogenous “European” identity, Elhaik said.
“By contrast, GPS represents a paradigm shift in population genetics whereby all populations are considered admixed to various degrees.”
oh my god they did it!
