Science is starting to pay big for a small minority who land major prizes. At a ceremony in California on Sunday night, six researchers became substantially wealthier when they were handed Breakthrough prizes, set up by the Russian billionaire Yuri Milner along with some of the biggest names in Silicon Valley.

Among those honoured were Karl Deisseroth of Stanford University and Edward Boyden of MIT for developing a procedure called optogenetics – a means of turning neurons on and off using light. They took home $3m (£2m) apiece for winning the Breakthrough prize in life sciences.

The same prize winnings went to John Hardy, who studies Alzheimer’s disease at University College London; Helen Hobbs, of the University of Texas South-western medical centre, for discovering gene variants linked to cholesterol; Svante Pääbo at the Max Planck Institute for Evolutionary Anthropology in Leipzig for reading Neanderthal and other ancient genomes; and Ian Agol, a mathematician at the Institute for Advanced Study in Princeton, for his work on problems that language cannot easily convey: virtual Hakenvirtual fibering conjectures and tameness.

A group of 1,300 researchers won the Breakthrough prize in fundamental physics, but the $3m will be shared among five team leaders whose experiments confirmed that ghostly subatomic particles called neutrinos have mass. The same landmark discovery won the Nobel prize in physics this year.

In keeping with Milner’s aim of raising scientists to rock star status in the eyes of the public, the Breakthrough prizes – sometimes called the Oscars of science – were handed out at a ceremony at Hangar One in Silicon Valley hosted by Seth MacFarlane, the creator of Family Guy.

Pharrell Williams was down to perform, with Russell Crowe, Hilary Swank and Lily Collins among the guest presenters. The plan for the evening, with a theme of “life in the universe”, included a live video link to the Nasa astronaut Scott Kelly on the International Space Station.

The prizes, totalling $21.9m this year – taking the total handed out to more than $160m since they were established in 2012 – are backed by Facebook’s Mark Zuckerberg and his partner, Priscilla Chan, Google’s Sergey Brin, Anne Wojcicki of 23andme, and Jack Ma of Alibaba.com and his wife, Cathy Zhang. Unlike Nobel prizes, the Breakthrough prizes are explicitly directed at researchers who are still active in their fields.

Hardy, nicknamed Scruffy by his former colleagues – he was once crowned the worst dressed scientist in the field at a major neuroscience conference – won the prize for his discovery of genetic mutations that give rise to early-onset Alzheimer’s disease, and for inspiring new treatments for preventing the disease.

He said he was having bacon and eggs in his kitchen one Saturday morning when Mahlon DeLong, a US neurologist from the prize committee, called with the news of his win. “I was speechless. It was a 15-minute call that changed my life. I had to have another cup of coffee,” he said.

Hardy is the most cited Alzheimer’s researcher in Britain, and may be the most storied too. He once rang up a $1,000 bill at an Osaka karaoke bar, drinking whiskey and singing Yellow Submarine, while in the city for a conference. One tale has him travelling with a colleague and mistakenly picking up the wrong suitcase before retiring to bed. The next day, Hardy appeared in the other man’s clothes. “He said he just thought his wife had bought him some new clothes,” a former colleague, Karen Duff, told the journal Nature Medicine in 2004.

He made a major breakthrough in 1990 at Imperial College London when his team found mutations that helped to explain how amyloid plaques form in the brain. Later, he showed that tangles of a protein called tau appeared to happen as the disease progressed. It was part of a strategy to understand the order in which Alzheimer’s takes hold.

Instagram Takes on Snapchat With Its New Video Channel – JESSI HEMPEL : 10.31.15. . 4:00 PM


Halloween is a gigantic social media smorgasbord, and few places are better to sample the delights than Instagram. Pet parades. Small children in Elsa costumes. Adults in Elsa costumes. It’s AWESOME. Which makes it the perfect holiday for Instagram to roll out its new video channel.

That’s right, Instagram is launching a video channel—a heavily curated, 24-hour deep dive into the very best videos Instagrammers post. Starting at 1pm on Saturday, Americans can pull up the app, click on the explore tab, and land in an immersive video viewer that will allow them to watch programming from all over the country. It’s like a pop-up cable network dedicated to Halloween.

The latest advance in 3D printing: replacement teeth – Dominic Basulto for the Washington Post Saturday 31 October 2015 07.00 EDT


Bacteria-fighting plastic could be the future of dentistry

The latest 3D printing innovation could change the way you think about your visit to the dentist. That’s because Dutch researchers at the University of Groningen are working on the creation of a 3D-printed tooth made of an antimicrobial plastic that kills the bacteria responsible for tooth decay on contact.

Imagine teeth that remain white and pristine over time, without all the accumulation of bacteria that cause dental problems. While the thought of having a 3D-printed tooth inside your mouth might not sound so great, is it really any worse than dealing with the constant toothache from a decaying tooth?

For the Dutch researchers, the key step in developing the bacteria-fighting tooth was being able to find the right material to put inside the 3D printer. In this case, the researchers embedded antimicrobial quaternary ammonium salts inside existing dental resin polymers. Once this mix is put into a 3D printer, it can be hardened with ultraviolet light and used to print out 3D replacement teeth.

To test the bacteria-fighting tooth in a lab environment, the researchers coated the material with human saliva and exposed it to the bacterium that causes tooth decay. The anti-bacterial tooth killed more than 99% of all bacteria and showed no signs of being harmful to human cells.

No More Pencils, No More Books – By Will Oremus OCT. 25 2015 8:26 PM


Artificially intelligent software is replacing the textbook—and reshaping American education.

Eighteen students file into a brightly lit classroom. Arrayed around its perimeter are 18 computers. The students take their seats, log in to their machines, and silently begin working. At a desk in the back, the instructor’s screen displays a series of spreadsheets and data visualizations to help her track each student’s progress in real time.

This isn’t a Vulcan finishing school or a scene from some Back to the Futuresequel. It’s Sheela Whelan’s pre-algebra class at Westchester Community College in Valhalla, New York.

The students in Whelan’s class are all using the same program, called ALEKS. But peek over their shoulders and you’ll see that each student is working on a different sort of problem. A young woman near the corner of the room is plugging her way through a basic linear equation. The young man to her left is trying to wrap his mind around a story problem involving fractions. Nearby, a more advanced student is simplifying equations that involve both variables and fractions.

At first glance, each student appears to be at a different point in the course. And that’s true, in one sense. But it’s more accurate to say that the course is literally different for each student.

Just a third of the way through the semester, a few of the most advanced students are nearly ready for the final exam. Others lag far behind. They’re all responsible for mastering the same concepts and skills. But the order in which they tackle them, and the pace at which they do so, is up to the artificially intelligent software that’s guiding them through the material and assessing their performance at every turn.
