On February 15, 2013, an asteroid entered the Earth’s atmosphere over the southern Ural region of Russia and exploded. The event was witnessed by thousands of people and became the largest known airburst since the 1908 Tunguska event. The blast produced a light brighter than the Sun, and the shock wave was felt by people all over the area. The energy of the explosion was equivalent to 20-30 of the atomic bombs used at Hiroshima. The asteroid was not detected by the authorities before the airburst, and the event surprised many people. It wounded 1,500 and damaged over 7,000 buildings. The meteor was caught on tape by multiple sources, which shows a giant fireball in the sky - followed by an enormous explosion of light. It was reported that the meteor made the ground hot, and the city smelled like gunpowder after the explosion. The event was an extremely rare occurrence and the only time in history that a meteor has been known to cause human injury.

On October 8, 1871, the Midwestern United States experienced an enormous firestorm that burned 6,100 square kilometres (2,300 sq mi) of land around Peshtigo, Wisconsin. The event is the deadliest fire in US history and killed 1,500 to 2,500 people. On the same day, the United States experienced the Great Chicago Fire, the Port Huron Fire, the Holland Fire, and Manistee Fire. The 1871 firestorm was caused by strong winds and forest fires. After gaining enough energy, the blaze quickly developed into a massive wall of fire that reached a speed of 160 kph (100 mph) and produced tornado-style winds. The fire was so hot that sandy beaches were turned to glass, and people were incinerated. The fire jumped over the waters of Green Bay and destroyed 12 separate communities in the area. It tossed rail cars and houses into the air and left thousands of people with nothing.

Many vegetarians make their decision not to eat meat based solely on ethics rather than any disdain for the flavour. The growing of meat in laboratories would certainly alleviate these concerns, but the benefits extend beyond morals. The keeping of animals for meat is an enormous strain on the environment, and with the global population skyrocketing, the demand continues to grow. According to a report published by Stanford University, livestock production occupies more than one-fourth of Earth’s land, and contributes to 18 percent of greenhouse gas emissions attacking the atmosphere. Recent experiments using stem cells from pigs and cows, cultured in a nutrient-rich bath that allows them to grow, have shown much promise.

Sunny day for a drive Imagine never having to fill your fuel tank again. With the cost of gas these days, that may sound like wishful thinking. But as solar technology becomes more advanced, that dream could soon become a reality. In fact, vehicles that run entirely on solar power are nothing new; the first solar vehicles were built in the 1950s. Those early models weren't very practical, but modern designs have made impressive progress. Solar milestones have been made for just about every form of transportation that you can imagine. There are solar cars, of course, but there are also solar buses, trains, boats, and even a solar helicopter. Here's our rundown of seven modern solar-powered vehicles.

Money, revenge, pure insanity - these are the main reasons why these women committed their crimes. Some operated alone, and some had accomplices, but they had one thing in common: pure evil. Beverley Allitt Beverley Allitt was born in 1968 and started working as a paediatric nurse in 1991. During a period of 58 days, she murdered four children and attacked another nine, who were lucky enough to survive. From an early age, she showed signs of Münchausen syndrome and later Münchausen by proxy, which may explain her actions. Münchausen is a mental disorder in which a person feigns illness or trauma to attract attention. She was finally arrested and tried at Nottingham Crown Court in 1993, pleading not guilty. She received 13 life sentences for murder and attempted murder.

The AC-130 Spectre (that big-ass plane from the Call of Duty games) probably isn’t going to be a new piece of technology to most of the people reading this, due to its aforementioned inclusion in a popular video game series. However, it’s the sheer amount of fire-power this thing possesses, combined with how little any given person can do about it, that we think will be surprising to people. If you’ve played the games, you no doubt know that the AC-130 gunship is able to rain down death from a mile in the sky, literally hitting enemies through windows, and even when they’re within spitting distance of a friendly combatant. Along with this frankly insane amount of firepower it has at its disposal, the AC-130 also packs something colloquially known as “Angel Flares,” a combination of chaff and flares which make the AC-130 all but invincible to all known lock-on technology.

The 1692 Salem Witch Trials are everyone’s favourite example of mob mentality, and although the incident has been discussed to death, it’s worth mentioning. It truly epitomizes what can happen when religious extremism and mobs collide. In fact, this incident made such an impression that - over 320 years later - we still use the phrase “witch hunt” to describe people being senselessly persecuted. No doubt you’ve heard the story: a couple of girls started acting weird (having fits, diving under furniture, contorting in pain, etc.) and claimed witches were responsible for their “sickness.” They pointed fingers at specific women in Salem, and after the doctor confirmed the girls were possessed, the already witch-phobic town went berserk. Salem officials started arresting suspected witches based on the flimsiest evidence (accusations from little girls), and the town went along with the whole thing, relishing in the witches’ destruction.

It's not often that some event comes along to really show humanity its true place in the universe, but two NASA spacecraft have just managed just that. I'm talking, of course, about the spectacular NASA photos of Earth as it appeared from Saturn —nearly 900 million miles away (1.4 billion kilometers) —as well as a photo of our planet as it appeared from Mercury, nearly 61 million miles (98 million km) distant. NASA took the photos Friday (July 19) using the Cassini spacecraft around Saturn and the Messenger spacecraft around Mercury as part of a global campaign to show the world how the solar system views our planet Earth. The space agency even worked to coordinate campaigns to involve space fans by having them wave at Saturn. The images, by far, are amazing. Earth and its moon stand out as bright pinpricks of light in Messenger's view from Mercury, while our planet is a pale, fuzzy dot nestled between Saturn's rings in the Cassini view. From my perspectiv...

fastest growing industries of 2013e created an infographic detailing the seven fastest growing industries in 2013. The report is based on data collected by market research firm Ibis World, which said “these industries are expected to continue their meteoric rise and far outpace the rest of the economy.” Five of these seven sectors relate to emerging forms of technology - green tech, online education, social games, mobile apps, and 3D printing - underscoring the idea that innovation leads to job creation. Furthermore, many of the businesses in these areas are contributing in other ways as well. Development and adoption of green tech is instrumental in curbing the growing dangers of climate change and online education can cut down on the massive amount of student debt in this country, while also giving people the skills they need to find gainful employment. 3D printing has led to a revolution in manufacturing and is causing amazing innovations in healthcare. Information is prol...

The first powered airship took to the skies on September 24, 1852, and the golden age of this type of aircraft ended with the tragic Hindenburg disaster on May 6, 1937. These days, we mostly see airships in the form of floating billboards. However, some have refused to let go of the notion that airships may have an important role to play in the future of air travel. Science fiction authors and filmmakers often feature reinvented takes on airships. And as it turns out, they could be onto something. Manufactured by Montebello, California-based American aircraft company the Worldwide Aeros Corporation, the Aeroscraft is a far cry from the blimps of the past. From its rigid structure to its control of static heaviness (COSH) system, it’s a modern aircraft that incorporates many cutting edge and ground-breaking technologies. The first functioning prototype, a more basic model known as The Pelican, was successfully floated on January 3, 2013 in Tustin, California. The Pelican w...

Depleted uranium rounds sound exactly like the kind of thing you’d want to stay right the hell away form. Even with the “depleted” bit thrown in there, these things still sound worse than wasps made of anthrax. In a nutshell, depleted uranium rounds are exactly what you’d expect: rounds with a small amount of uranium crammed in them, because the pointy metal thing that flew at you at 400 MPH wasn’t dangerous enough. It’s not what these rounds do to the human body that makes them terrifying though; it’s what they do to armour.

Remains of shipwrecks and rusted machinery stretch out on the rocks of South Africa’s Cape of Good Hope like the carcasses of extinct beasts. Casualties of the extreme weather that gave the area the nickname Cape of Storms, these abandonments have been left to deteriorate as a reminder to sailors of just how perilous the waters can be. While the intersection of cold swells from Antarctica and a warm current of the Indian Ocean is responsible for most of the danger, the former lighthouse - which wasn’t quite tall enough to be of much use - certainly didn’t help. A 5,500-ton Portuguese ship called the Lusitania is among those to have wrecked here. The Cape is also the setting for the myth of The Flying Dutchman, a ghost ship doomed to sail the seas forever.

The modern ghost town of Kilamba isn’t something you’d expect to find in Angola - indeed, it’s highly reminiscent of China’s ghost town of Ordos City. That’s because it was built by the China International Trust and Investment Corporation, financed by a Chinese credit line and repaid by the Angolan government with oil. The series of 750 eight-story apartment blocks, along with over 100 commercial complexes and a dozen

Honoré Fragonard was a bit of an odd sausage to say the least. The anatomist, who lived from 1732 to 1799, was a pioneer of his day. “Ecorchés” are flayed figures depicting the body without skin - essentially a naked body of muscles. Before Fragonard came along, ecorchés were imagined works of art: paintings and sculptures of the male or female form. Fragonard, however, had other ideas. He created his ecorchés from actual corpses.

Months before Hurricane Sandy hurled the Atlantic Ocean into houses and cities along the East Coast, another record-breaking cyclone battered North America, helping push this year's Arctic sea ice to a record low, a new study finds. Arctic sea ice has been declining for decades, reaching a record low in September 2007 and hitting that record again in 2012.  "The Great Arctic Cyclone of August 2012" arose in Siberia on Aug. 2 and crossed the Arctic Ocean to Canada, lasting an unusually long 13 days. The cyclone hit a pressure minimum of 966 millibars on Aug. 6, the lowest ever recorded for an Arctic storm, professors Ian Simmonds and Irina Rudeva of the University of Melbourne in Australia report in the Dec. 15 issue of the journal Geophysical Research Letters. The pressure reading is only 26 mb higher than Hurricane Sandy's record low of 940 mb. (A typical low-pressure system usually hits around 1,000 mb.) "This pressure minimum and cyclone long...

Most Amazing The Pavilion Protects Your Car and and VOLVO Developers The 'NO DEATH' CAR Although solar power is a resource that most of us agree we should be taking far more advantage of, the truth is that solar panels are often just as visually uncool as they are inefficient relative to other sources of energy. However, as manufacturing processes evolve to allow for more adventurous designs, the shift to aesthetically pleasing solar harvesters is gathering momentum, as exemplified by this new device created as an add-on to Volvo's V60 electric vehicle. Designed by Los Angles-based architecture studio Synthesis, the idea is the winner of the international "Switch to Pure Volvo" competition that called for an innovative solution to showcase the automaker's latest electric vehicle. The collapsible pavilion uses integrated photovoltaic panels tensioned over carbon fibre rods to create an attractively futuristic butterfly wing-like covering that bot...

Health and Medicine Vaccination Strategy May Hold Key to Ridding HIV Infection from Immune System, AIDS experts at Johns Hopkins have figured out a way to kill off latent forms of HIV that hide in infected T cells long after antiretroviral therapy has successfully stalled viral replication to undetectable levels in blood tests. HIV has long been known to persist in a dormant, inactive state inside immune system T cells even long after potent drugs have stopped the virus from making copies of itself to infect other cells. But once treatment is stopped or interrupted, the latent virus quickly reactivates, HIV disease progresses, and researchers say it has proven all but impossible to wipe out these pockets of infection. Johns Hopkins senior study investigator and infectious disease specialist Robert Siliciano, M.D., Ph.D., who in 1995 first showed that reservoirs of dormant virus survived, says the resulting need for lifelong drug treatment has raised concerns about the...

By engineering cells to express a modified RNA called "Spinach," researchers have imaged small-molecule metabolites in living cells and observed how their levels change over time. Metabolites are the products of individual cell metabolism. The ability to measure their rate of production could be used to recognize a cell gone metabolically awry, as in cancer, or identify the drug that can restore the cell's metabolites to normal. "The ability to see metabolites in action will offer us new and powerful clues into how they are altered in disease and help us find treatments that can restore their levels to normal," says Dr. Samie R. Jaffrey, an associate professor of pharmacology at Weill Cornell Medical College. Dr. Jaffrey led the study, which included three other Weill Cornell investigators. "Metabolite levels in cells control so many aspects of their function, and because of this, they provide a powerful snapshot of what is going on inside a c...
