When you sit back and think about how far away exoplanets are — and how faint — it’s a scientific feat that we can find these distant worlds outside our Solar System at all. It’s even harder to learn about the world if the exoplanet is orbiting a dim star — say, about two-thirds the size of the Sun — that is faint through even the largest telescope.
Above is a recent 3-D version of a panoramic view from NASA of the Curiosity Mars rover, made from dozens of images from both the left and right Navcams. But panoramic specialist John O’Connor has also put together a non-3-D interactive view of this scene of the rover and its surroundings. The images were taken during the 166th, 168th and 169th Martian days, or sols, of Curiosity’s work on Mars, which equates to Jan. 23, 25 and 26, 2013 here on Earth.
Americans are increasingly leaving the country to seek an education in Canada, where college tuition costs are significantly lower and the quality of education is high. Over the past decade, the number of Americans who enrolled in Canadian colleges has risen by 50 percent. About 10,000 Americans are currently enrolled at universities in Canada, the [...]
We live on a planet dominated by weather. But not just the kind that comes in the form of wind, rain, and snow — we are also under the influence of space weather, generated by the incredible power of our home star a “mere” 93 million miles away. As we orbit the Sun our planet is, in effect, inside its outer atmosphere, and as such is subject to the constantly-flowing wind of charged particles and occasional outbursts of radiation and material that it releases. Although it may sound like something from science fiction, space weather is very real… and the more we rely on sensitive electronics and satellites in orbit, the more we’ll need to have accurate weather reports.
It’s been almost 70 years since World War II. However, the Nazi party, and their symbols, remains fresh in the minds of many as allegories of pure evil.
Last fall, shoppers outside a Macy’s store in Boston were given a chance to test drive a robot. They were invited, compliments of Brigham and Women’s Hospital, to sit at a console and move the machine’s arm the same way surgeons would in an operating room.
Using ESO’s Very Large Telescope along with other radio telescopes, John Antoniadis, a PhD student at the Max Planck Institute for radio Astronomy (MPIfR) in Bonn and lead author of the paper, says the bizarre pair of stars makes for an excellent test case for physics.
Knowledge of Earth’s location in the universe has been shaped by 400 years of telescopic observations, and has expanded radically in the last century. Initially, Earth was believed to be the center of the universe, which consisted only of those planets visible with the naked eye and an outlying sphere of fixed stars. After the acceptance of the heliocentric model in the 17th century, observations by William Herschel and others showed that the Sun lay within a vast, disc-shaped galaxy of stars, later revealed to be similar to our own. By the 20th century, observations of spiral nebulae revealed that our galaxy was only one of billions in an expanding universe, grouped into clusters and superclusters
This year, prolonged extreme temperatures and seemingly never-ending snowstorms in the United States forced many inside, seeking shelter from what felt like an unusually long winter. This meant some of us were stuck in bed for a day or two clutching a box of Kleenex and downing cough syrup. That’s because viruses that cause the common cold love enclosed spaces with lots of people—the family room, the office, the gym.
by Mike Barrett Showcasing once again how numerous food-based substances are able to both treat and protect against cancer, scientists from the Texas Biomedical Research Institute have found for the first time that a natural, plant-derived substance known as gossypin is capable of treating the deadliest form of skin cancer – melanoma. In the study, published in the journal Molecular Cancer Therapeutics, researchers found gossypin was [...]
While there are many illegal drugs much worse than marijuana or alcohol, what many don’t realize is just how many drugs are perfectly legal and obtainable over the counter, that are far stronger and more dangerous than the illegal ones.
Anyone who has read a Richard Preston book, such as The Hot Zone or Panic in Level 4, knows the danger of tampering with wildlife. The story usually goes something like this: Intrepid explorers venture into a dark, bat infested cave in the heart of East Africa, only to encounter something unseen and living, which takes up residence in their bodies. Unknowingly infected, the happy travelers jump on a plane back to Europe or the States, spreading their deadly pathogen willy-nilly to every human they encounter upon the way. Those people, in turn, bring the novel virus or bacterium back home to strangers and loved ones alike. Before the world knows it, a pandemic has arrived.

Many countries today pride themselves on the amazing military vehicles that they’re capable of producing. However, judging by what some used to call a tank, they haven’t always had this skill.
After the Civil War, the availability of natural resources, new inventions, and a receptive market combined to fuel an industrial boom. The demand for labor grew, and in the late 19th and early 20th centuries many children were drawn into the labor force. Factory wages were so low that children often had to work to help support their families. The number of children under the age of 15 who worked in industrial jobs for wages climbed from 1.5 million in 1890 to 2 million in 1910.
