Bees evolved from ancient supercontinent, diversified faster than suspected      (via sciencedaily.com)     Original source 

The origin of bees is tens of millions of years older than most previous estimates, a new study shows. A team led by Washington State University researchers traced the bee genealogy back more than 120 million years to an ancient supercontinent, Gondwana, which included today's continents of Africa and South America.

Mutation accessibility fuels influenza evolution      (via sciencedaily.com)     Original source 

Scientists showed that fixed mutations within a viral population most likely stem from how easy it is to acquire that mutation (i.e., mutation accessibility) rather than just its benefit.

Reinforcement learning allows underwater robots to locate and track objects underwater      (via sciencedaily.com) 

A team has shown that reinforcement learning -i.e., a neural network that learns the best action to perform at each moment based on a series of rewards- allows autonomous vehicles and underwater robots to locate and carefully track marine objects and animals.

Breakthrough in Monte Carlo computer simulations      (via sciencedaily.com) 

Researchers have developed a highly efficient method to investigate systems with long-range interactions that were previously puzzling to experts. These systems can be gases or even solid materials such as magnets whose atoms interact not only with their neighbors but also far beyond.

'Swine flu' strain has passed from humans to swine nearly 400 times since 2009      (via sciencedaily.com)     Original source 

A new study of the strain of influenza A responsible for the 2009 H1N1 pandemic -- pdm09 -- shows that the virus has passed from humans to swine about 370 times since 2009, and subsequent circulation in swine has resulted in the evolution of pdm09 variants that then jumped from swine to humans.

New archosaur species shows that precursor of dinosaurs and pterosaurs was armored      (via sciencedaily.com)     Original source 

Researchers have described a new species of armored reptile that lived near the time of the first appearance of dinosaurs. With bony plates on its backbone, this archosaur fossil reveals that armor was a boomerang trait in the story of dinosaur and pterosaur evolution: the group's ancestors were armored, but this characteristic was lost and then independently re-evolved multiple times later among specialized dinosaurs like ankylosaurs, stegosaurs, and others.

Why computer security advice is more confusing than it should be      (via sciencedaily.com) 

If you find the computer security guidelines you get at work confusing and not very useful, you're not alone. A new study highlights a key problem with how these guidelines are created, and outlines simple steps that would improve them -- and probably make your computer safer.

Detecting threats beyond the limits of human, sensor sight      (via sciencedaily.com)     Original source 

A new patented software system can find the curves of motion in streaming video and images from satellites, drones and far-range security cameras and turn them into signals to find and track moving objects as small as one pixel. The developers say this system can enhance the performance of any remote sensing application.

Genetic secrets of America's favorite snack      (via sciencedaily.com)     Original source 

In its simplest form, popcorn is pretty uncomplicated. Most supermarket varieties offer the choice of two kernel colors, yellow or white, and two kernel shapes, pointed or pearl. When popped, the flake typically expands into one of two shapes: mushroom or butterfly. But there's more to popcorn than meets the eye. New research reveals a wealth of untapped diversity lurking in popcorn's genetic code.

What math can teach us about standing up to bullies      (via sciencedaily.com)     Original source 

New research from Dartmouth takes a fresh look at game theory to show that being uncooperative can help people on the weaker side of a power dynamic achieve a more equal outcome -- and even inflict some loss on their abusive counterpart. The findings can be applied to help equalize the balance of power in labor negotiations, international relations and everyday interactions, as well as integrate cooperation into interconnected AI systems such as driverless cars.

Humans' ancestors survived the asteroid impact that killed the dinosaurs      (via sciencedaily.com)     Original source 

A Cretaceous origin for placental mammals, the group that includes humans, dogs and bats, has been revealed by in-depth analysis of the fossil record, showing they co-existed with dinosaurs for a short time before the dinosaurs went extinct.

50-million-year-old katydid fossil reveals muscles, digestive tract, glands and a testicle      (via sciencedaily.com)     Original source 

50 million years ago in what is now northwestern Colorado, a katydid died, sank to the bottom of a lake and was quickly buried in fine sediments, where it remained until its compressed fossil was recovered in recent years. When researchers examined the fossil under a microscope, they saw that not only had many of the insect's hard structures been preserved in the compressed shale, so had several internal organs and tissues, which are not normally fossilized.

How coral reefs can survive climate change      (via sciencedaily.com)     Original source 

Similar to the expeditions of a hundred or two hundred years ago, the Tara Pacific expedition lasted over two years. The goal: to research the conditions for life and survival of corals. The ship crossed the entire Pacific Ocean, assembling the largest genetic inventory conducted in any marine system to date. The team's 70 scientists from eight countries took around 58,000 samples from the hundred coral reefs studied.
