Sixteen years ago, British researcher Ewan Birney launched an unusual sweepstake. At the time, scientists were completing the Human Genome Project, the international effort to unravel the genetic makeup of human beings. But how many individual human genes would be revealed when the project was completed, Birney wondered? So he asked the world's top geneticists to each bet a dollar on the outcome.
This might have seemed a rather tardy question, given that the project had already consumed “the best part of a decade, the invention of brand new technologies, unprecedented computing power and $3bn”, as Adam Rutherford notes. Late or not, Birney's query nevertheless produced a striking answer.

A beautiful sunset ignites the new ice forming in Arthur Harbor at Palmer Station on Anvers Island. Palmer Station is slightly above the Antarctic Circle (66.5 degrees) at 64.77 degrees latitude, consequently the sun never sets permanently during the winter months. However, sunsets are longer due to its low angle.

When asked to visualize your childhood home, you can probably picture not only the house you lived in, but also the buildings next door and across the street. MIT neuroscientists have now identified two brain regions that are involved in creating these panoramic memories. As we look at a scene, visual information flows from our retinas into the brain, which has regions that are responsible for processing different elements of what we see, such as faces or objects. The team suspected that areas involved in processing scenes -- the occipital place area (OPA), the retrosplenial complex (RSC), and parahippocampal place area (PPA) -- might also be involved in generating panoramic memories of a place. These brain regions help us to merge fleeting views of our surroundings into a seamless, 360-degree panorama, the researchers say.

The epic, widely celebrated Sapiens gets the sequel it demanded: a breathless, compulsive inquiry into humanity's apocalyptic, tech-driven future
Yuval Noah Harari began his academic career as a researcher of medieval warfare. His early publications had titles like “Inter-frontal Cooperation in the Fourteenth Century and Edward III's 1346 Campaign” or “The Military Role of the Frankish Turcopoles”. Then, the story goes, having won tenure at the Hebrew University of Jerusalem, he embarked on a crusade of his own. He was invited to teach a course that no one else in the faculty fancied a broad-brush introduction to the whole of human activity on the planet. That course became a widely celebrated book, Sapiens, championed by Mark Zuckerberg, Bill Gates and Barack Obama, and translated into 40 languages. It satisfied perfectly an urgent desire for grand narrative in our fragmenting Buzz-fed world. The rest is macro-history.

Continue reading...It's a story that has been told many times, but this new take on the revolution in astronomy from Newton to Einstein is a fresh, smartly-paced read
Isaac Newton set it up for Albert Einstein: he calculated a system of heavenly motion that governed the entire measurable cosmos. He then added a challenge: a theory, he wrote “that agrees exactly with exact astronomical observations cannot fail to be true.”
He didn't live to find out quite how much frustration that claim would give his fellow astronomers, who identified Uranus, and then from the behaviour of Uranus inferred the existence of another planet, and finally identified Neptune. They relied on Newton's predictions, which were spot on and self-evidently right, all the way to the edge of the solar system - except for one tiny little niggling detail about the planet closest to the sun.

Flying people to an asteroid is really hard, so NASA wants to bring part of it to them. But some former astronauts say the $2 billion plan was born of politics and budget cuts, and makes little sense.

Indigo buntings often migrate by night, using the stars to navigate. The seasonality of bird migration is shifting in response to climate change. As a result, birds in the United States are arriving at their northern breeding grounds earlier in spring -- and may be departing later in fall. Scientists supported by the National Science Foundation made the migration shift discovery thanks to information aggregated from two sources: remote-sensing data from weather surveillance radar and ground-based data collected in citizen science databases.

The ubiquity of smartphones and their sophisticated gadgetry makes them an ideal tool to steal sensitive data from 3-D printers. That's according to a new University at Buffalo study that explores security vulnerabilities of 3-D printing, also called additive manufacturing, which analysts say will become a multibillion-dollar industry employed to build everything from rocket engines to heart valves. Unlike most security hacks, the researchers did not simulate a cyberattack. Instead, the researchers programmed a common smartphone's built-in sensors to measure electromagnetic energy and acoustic waves that emanate from 3-D printers. These sensors can infer the location of the print nozzle as it moves to create the three-dimensional object being printed. According to the researchers, the tests show that smartphones are quite capable of retrieving enough data to put sensitive information at risk.
