Sweeping hormones makes stock brokers take riskier decisions

stressed brokers

It’s not just teenagers who let hormones get the best of them, stock brokers do it all the time, according to a new study. Only, in this case, the consequences might be far worse than a family meltdown: we’re talking about global markets crashes.

One in Eight HIV-positive Americans are not aware they’re carrying the virus

HIV blood test

A new extensive report carried out by the Centers for Disease Control and Prevention (CDC) found approximately 1 in 8 Americans with human immunodeficiency disease (HIV) are unaware of their condition. Overall, that means 14 percent of undiagnosed cases among 1.2 million patients with HIV in the US. An undiagnosed population is the prime contributor to the spread of the disease. Clearly, there’s much room for improvement.

This baby was born with a rare condition that deformed his skull

Matthew Boler

Meet Matthew, a bright eyes, chubby cheeked baby. On the outside he looks and behaves like any regular baby his age, with one exception: an usually oblong-shaped head. At first, his parents dismissed it as a family feature, but when Matthew turned two months and visited the pediatrician for his regular check-up the doctor immediately knew something was wrong when

Scientists control the path of lightning using lasers

Thousands of lightning bolts strike the Earth’s surface roughly every couple of seconds, but despite their ubiquity this phenomena is somewhat poorly understand. Lightning is also unpredictable. While humans have been placing lightning rods for centuries to increase the probability of striking in a certain fixed point, its path can not be controlled. That may be true in nature, but in the confinement of a lab of the INRS Énergie Matériaux Télécommunications research centre (Varennes, QC, Canada), scientists have defied this common knowledge and used lasers to coax lighting to follow a predefined path.

The Moon is shrouded by a dust cloud, and a mystery still stands

The Moon doesn’t have an atmosphere, but it is surrounded by a thick dust cloud; the dust constantly falls down to the lunar surface, but new dust constantly jumps to replenish it. The pattern of dust falling back to its home “in due time … will fill in craters,” says the University of Colorado, Boulder’s Mihaly Horanyi, who led the team

Scientists find how worms brains’ feel magnetism

It’s no secret that many animals can sense the Earth’s magnetic field, but until now, researchers didn’t know exactly how they could do this – what the sensor was. Now, a team from the University of Texas at Austin has found a simple, antenna-like structure in the brain of the simple worm C. Elegans that appears to be able to detect magnetic fields.

Musk seeks permission from the FCC to test his ambitious space internet

Later last year, ZME Science revealed that one of Elon Musk’s top priorities in the future is deploying a massive fleet of micro-satellites into Earth’s low orbit to provide internet and mobile data. The plan is to serve internet to billions in the developing world, but to do so the service needs to be very, very cheap. At the same time, while launching thousands of satellites into space doesn’t sound particularly cheap, but if there’s any company good at launching cargo into space affordably that’s SpaceX. This isn’t exactly a pipe dream, and Musk seems very serious about it considering he just filled an official request to the FCC to gain permission for a test of the satellite internet, according to the Washington Post.

Pick-a-boo: the secret life of Serengeti wildlife caught in 1.2 million photos

After placing no less than 225 camera traps, a group of researchers has collected a massive database of 1.2 million photos documenting the secret live of the animals that roam Tanzania’s Serengeti National Park. The shots offer a raw, unedited glimpse that wouldn’t had been possible otherwise; genuinely up close and personal. So personal that some of the lions and other beasrs in the park went a step too far and tried to eat the cameras. At time, the only thing that was left of the camera was plastic shreds, but luckily some memory cards survived. How often do you get to see the last shot made by a camera? With a lion with a fully open jaws staring right at you, no less.

Life priorities by country around the world [infographic]

Brazil

Around 80,000 people around the world answered a questionnaire that gauged what they valued most in life. Their responses were centralized and normalized by the OECD Better Life Index, and used to design an infographic. Labeled over each of the 180 countries, you can see what’s the dominant life priority of the population.

Tiny origami bot folds, navigates obstacles, swims, then dissolves. Next: inside your body

origami bot

At the International Conference on Robotics and Automation (ICRA) conference, a team from MIT, in collaboration wit the Technische Universitat in Germany, presented an incredible origami bot that can perform various complex motor tasks. Weighing only 0.3 grams, the bot can scuttle at about 4 cm/sec to crawl up an arm, carry twice its load, dig through a pile of foam, climb a ramp or push a tiny puck along a planned trajectory. At the end, the researchers demonstrate how the entire bot (apart from its magnet) can be dissolved in acetone. Later on, it’s easy to imagine a similar origami bot traveling through your body where it performs various tasks like deliver a medical payload, diagnose for diseases or even perform surgery. It would be designed to be much smaller and with all its parts dissoalvable inside the human body after a while or when emerged in a certain bodily solution.
