What Really Happens When Your Blood Boils?

From Live Science:

Probably. Blood pressure tends to spike when you are excited by an emotion such as anger or fear. But high blood pressure — known as "hypertension" — is very sneaky. It's called the "silent killer," because it usually has no symptoms.

Doctors say you have high blood pressure if you have a reading of 140/90 or higher. A blood pressure reading of 120/80 or lower is considered normal. "Prehypertension" is blood pressure between 120 and 139 for the top number, or between 80 and 89 for the bottom number.

They have been told as bedtime stories by generations of parents, but fairy tales such as Little Red Riding Hood may be even older than was previously thought.

A study by anthropologists has explored the origins of folk tales and traced the relationship between varients of the stories recounted by cultures around the world.

Hospitals Open The Door To Sci-Fi's Medical Robots

From The Independent:

Exhibition reveals huge advances that are turning futuristic fantasies into surgical reality.

From the tiny submarine injected into the human body in the film Fantastic Voyage in 1966, to the hologram Doctor in Star Trek: Voyager in 1995, medical robots have long fuelled the imaginations of science fiction writers.

Now many of those fantasies are coming true and on Tuesday the Royal College of Surgeons will exhibit some of the advances that in just five years could see tiny robots going to work inside patients.

Researchers Seek Funds To Study Cell Phone Safety

From CNET:

Are cell phones safe? For years, studies have provided conflicting conclusions. Today, there is still no clear answer. But experts agree on one thing: more research is needed to find out the answer.

In an effort to raise awareness among consumers and to urge government leaders to allocate more funding for research, an international group of researchers is gathering in Washington, D.C. later this month to present study findings and to lobby government officials.

Astronauts from the US space shuttle Discovery have made their third and final spacewalk, installing equipment on the International Space Station.

However, Nasa officials said one job had to be left undone after cables failed to connect.

Nasa flight director Heather Rarick said repairs to the connector would be attempted on a future mission, possibly Atlantis's flight in November.

The shuttle is due to leave on Tuesday and land back in Florida on Thursday.

From Science Daily:

ScienceDaily (Sep. 4, 2009) — Analysis of ancient DNA from skeletons suggests that Europe's first farmers were not the descendants of the people who settled the area after the retreat of the ice sheets. Instead, the early farmers probably migrated into major areas of central and eastern Europe about 7,500 years ago, bringing domesticated plants and animals with them, says Barbara Bramanti from Mainz University in Germany and colleagues.

From Live Science:

Remotely-operated vehicles, or ROVs, are underwater robots that can go where the environment is too deep or difficult for human divers. I learned how to design and build ROVs as a student in the electrical department at Long Beach City College (LBCC), where every year, students enrolled in the department's robotics class form a team that competes in the Marine Advanced Technology Education (MATE) Center's International Student ROV Competition.

The MATE competition is a pool-based competition that uses props to simulate realistic underwater workplaces. The MATE Center is one of eleven Advanced Technological Education (ATE) Centers established with funding from the National Science Foundation's ATE Program.

Robotics Rodeo Aims To Save Lives

A technician explains the controls of a remotely operated Bobcat machine to a Soldier. After some instruction, Soldiers were given hands-on experience with the equipment and offered their feedback

From Army.mil:

FORT HOOD, Texas (Sept. 2, 2009) -- A Robotics Rodeo began Tuesday with exhibitors from all over America descending on Fort Hood to show off the latest advancements in robotics technology.

"If we're not fielding, we're failing; it's all about saving Soldiers' lives," said Lt. Gen. Rick Lynch, III Corps commanding general. "It's not about technology demonstrations, not about how much money you can garner from the U.S. government, it's all about saving Soldiers lives."

From Live Science:

Wolves do better on some tests of logic than dogs, a new study found, revealing differences between the animals that scientists suspect result from dogs' domestication.

In experiments, dogs followed human cues to perform certain tasks despite evidence they could see suggesting a different strategy would be smarter, while wolves made the more logical choice based on their observations.

Arctic Ice Proves To Be Slippery Stuff -- Commentary

UN Secretary General Ban Ki-moon

From The Telegraph:

The extent of the sea-ice is now half a million square kilometres more than it was this time last year, says Christopher Booker.

BBC viewers were treated last week to the bizarre spectacle of Mr Ban
Ki-moon standing on an Arctic ice-floe making a series of statements so laughable that it was hard to believe such a man can be Secretary-General of the UN. Thanks to global warming, he claimed, "100 billion tons" of polar ice are melting each year, so that within 30 years the Arctic could be "ice-free". This was supported by a WWF claim that the ice is melting so fast that, by 2100, sea-levels could rise by 1.2 metres (four feet), which would lead to "floods affecting a quarter of the world".

New England Prep School Builds Library Without Books

“When I look at books, I see an outdated technology, like scrolls before books,’’ said headmaster James Tracy. (Mark Wilson for The Boston Globe)

Welcome to the library. Say goodbye to the books. -- Boston Globe

ASHBURNHAM - There are rolling hills and ivy-covered brick buildings. There are small classrooms, high-tech labs, and well-manicured fields. There’s even a clock tower with a massive bell that rings for special events.

Cushing Academy has all the hallmarks of a New England prep school, with one exception.

This year, after having amassed a collection of more than 20,000 books, officials at the pristine campus about 90 minutes west of Boston have decided the 144-year-old school no longer needs a traditional library. The academy’s administrators have decided to discard all their books and have given away half of what stocked their sprawling stacks - the classics, novels, poetry, biographies, tomes on every subject from the humanities to the sciences. The future, they believe, is digital.

Super-Strong German Steel Velcro: Not for Sneakers

Velcro of Steel: So strong, yet still removable TUM Institute of Metal Forming and Casting (utg)

From Popular Science:

German-created steel fasteners can withstand loads of more than 38 tons per square meter, hook and unhook without tools.

Velcro has proved plenty useful as a quick fastener on shoes and other household items, but lacks the strength to resist fiery temperatures and powerful chemicals in industrial settings. Now German scientists have taken the hook-and-loop fastener concept and developed a Superman version, called Metaklett.
