It has long been known that some people are better at navigating than others, but until now it has been unclear why. A new study shows that the strength and reliability of “homing signals” in the human brain vary among people and can predict navigational ability.
Uncork a bottle of champagne, and as the pressure of the liquid is abruptly removed, bubbles...
Satellite data shows that around many major U.S. cities, nighttime lights shine 20 to 50 percent...
The media is often accused of being perpetrators of bad news—that is, it takes every opportunity to report negative news. Take your local news channel, for example. I’d bet that on any given night, negative news reports outweigh positive reports by a ratio of 10:1. But, with the year coming to a close, I want to take time to highlight some of the positive strides society, specifically women in science, have made in 2014.
One day, hopefully sooner rather than later, a truly energy-efficient ultra-low temperature (ULT) freezer will reach the market. Unfortunately for now, no technology exists that provides significant gains in efficiency, without compromising unit stability. Energy efficiency should always be considered in today’s green world, but don’t ignore other important long-term considerations.
Smartphones and laptops have become essential tools for today's teenagers. But learning how these devices work has often taken a backseat to other priorities in U.S. schools. The White House wants to help change that direction. It announced that the seven largest school districts in the U.S. are joining more than 50 others to start offering introductory computer science to all their students.
Richard Hudson and his team at Twin Cities Public Television are putting middle school girls in front of a national audience on the PBS series "SciGirls." This is the first television science series designed specifically for girls, ages eight to 12, to inspire and empower them to consider careers in science, technology, engineering and math (STEM).
Postdoctoral scientists are the engines of biomedical research. As early career researchers, they conduct the most experiments and are responsible for sculpting how we treat disease in decades to come. But, as a major stakeholder in discussions about the future of biomedical research, their views are often overlooked.
The STEM fields of science, technology, engineering and mathematics supposedly suffer from a shortage of graduates. But, there are plenty of STEM graduates; the U.S. is just training them the wrong way. It’s true there are many professional STEM vacancies but there are also many STEM grads who could fill them. The problem is the current training pipeline doesn’t direct graduates to these non-academic jobs.
New research provides what the authors think is the first comprehensive picture of how Greenland’s ice is vanishing. It suggests that current ice sheet modeling studies are too simplistic to accurately predict future sea level rise, and that Greenland may lose ice more rapidly in the near future than previously thought.
Several experiments have helped explain some– but not all– of the imbalance between matter and antimatter in the universe. Now, a theorist and his colleagues have laid out a possible method for determining if the Higgs boson is involved.
Electronic cigarettes have surpassed traditional smoking in popularity among teens, the government's annual drug use survey finds. Even as tobacco smoking by teens dropped to new lows, use of e-cigarettes reached levels that surprised researchers.
Artificial electronic circuits that mimic the pathways connecting neurons in the brain can learn, unlearn and store memories, researchers have reported. These inventions could not only help researchers better understand how the brain works, but could also lead to advanced new computers.
People who own all-electric cars where coal generates the power may think they are helping the environment. But, a new study finds their vehicles actually make the air dirtier, worsening global warming. Ethanol isn't so green, either.
New findings could provide a pathway toward a kind of two-dimensional microchip that would make use of a characteristic of electrons other than their electrical charge, as in conventional electronics. The new approach is dubbed “valleytronics,” because it makes use of properties of an electron that can be depicted as a pair of deep valleys on a graph of their traits.
Researchers have found that brain stimulation may help retrain unhelpful cognitive habits associated with anxiety and depression. The study revealed that around 20 minutes of targeted electrical stimulation to a region of the frontal cortex could dramatically improve the effectiveness of a computer-based task designed to retrain unhelpful patterns of attention that are known to maintain high levels of anxiety.
When the people whose houses hug the narrow warren of streets paralleling the busiest urban freeway in America began to see bumper-to-bumper traffic crawling by their homes a year or so ago, they were baffled. When word spread that the explosively popular new smartphone app Waze was sending many of those cars through their neighborhood in a quest to shave five minutes off a daily rush-hour commute, they were angry and ready to fight back.
For decades, the mantra of electronics has been smaller, faster, cheaper. Today, engineers add a fourth word— taller. A team is revealing how to build “high-rise” chips that could leapfrog the performance of the single-story logic and memory chips on today's circuit cards.
Gustave Eiffel, born Dec. 15, 1832, was a French civil engineer and architect, most famous for the Eiffel Tower, built as the entrance arch for the 1889 World’s Fair in Paris. However, he started his career, in 1855, working as an unpaid assistant is his brother-in-law’s foundry.
The airspace over London was briefly closed Friday afternoon because of what authorities said was a computer failure at one of Britain's two air traffic control centers. The British government demanded an investigation into the "unacceptable" disruption. The 35-minute shutdown caused flight delays in and out of London and flight slowdowns in other parts of Europe that officials said would linger into Saturday.
For the first time, researchers have measured large distances in the Universe using data, rather than calculations related to general relativity. The team used data from astronomical surveys to measure a standard distance that is central to our understanding of the expansion of the universe.
Astronomers may have detected the dusty hallmarks of an entire family of Pluto-size objects swarming around an adolescent version of our own Sun. By making detailed observations of the protoplanetary disk surrounding the star, the astronomers detected an unexpected increase in the concentration of millimeter-size dust grains in the disk's outer reaches.
If you were naughty this year, you might end up with something big and boring, like a vacuum cleaner. If you were good, you might ask for one of these little high-tech gems instead.
The computer scientist credited with inventing the World Wide Web says affordable access to the Internet should be recognized as a human right, as a report showed that billions of people still cannot go online and government surveillance and censorship are increasing.
NASA, in partnership with the USGS, is offering more than $35,000 in prizes to citizen scientists for ideas that make use of climate data to address vulnerabilities faced by the U.S. in coping with climate change. The Climate Resilience Data Challenge kicks off Monday, Dec. 15, and runs through March 2015.
A groundbreaking diagnostic technique developed for Ground Zero workers that can identify hazardous particles in the lungs is moving to the playground to help asthmatic children.
The Standard Model of particle physics is a powerful mathematical model that has guided physicists to the discovery of the Higgs boson and other particles before it. Now, scientists have found a simplified mathematical description that is entirely consistent with the mathematics of the Standard Model but is an add-on that accounts for small deviations in the expected behavior of low mass particles.
A new app brings molecules to life in a handheld device. Through the app, people can use up to 11 fingers to examine in great detail more than 350 molecules, which they can also twist, turn and tie into knots.
