Seven Brilliant Lectures By Richard Feynman (Video)


Watch A Series Of Seven Brilliant Lectures By Richard Feynman -- io9

Richard Feynman was obviously famous for his work as a physicist, but he's also widely regarded as one of the most lucid and effective lecturers to ever address an audience. So renowned, so readily accessible were his presentations, that his introductory physics lectures (which he delivered to undergraduates at Caltech) have since been immortalized in the form of a three-volume set called, quite simply, The Feynman Lectures.

My Comment: I always loved his books and videos. It's good to see 7 of them together.

Why Women Moan During Sex


Why Women Moan During Sex -- CNN

Ian Kerner, a sexuality counselor and New York Times best-selling author, blogs about sex weekly on The Chart. Read more from him on his website, GoodInBed.
All you have to do is watch nearly any depiction of female orgasm on screen to get an idea of how a woman is “supposed” to react during sex.

From "When Harry Met Sally" to "Sex and the City" to your basic porn film, women in the throes of passion aren’t just shouting their ecstasy from the rooftops - they’re moaning with pleasure. Loudly.

But is this just cinematic license, or is there really something to noisy sex?

How Many X-37Bs Are There?


Just How Many X-37Bs Are There? -- Defense Tech

So Air Force Space Command boss Gen. William Shelton gave us a tiny bit more insight into the service’s super secret space spycraft, the X-37B, when he said that it’s doing its super secret — and year-long — mission excellently and that there’s no need for a bigger version of it or to increase the size of the X-37B fleet.

What was really interesting about his comments, was the fact that he wouldn’t say just how big the fleet is. Keep in mind that the service has said that it’s got two of the mini-shuttles for a while now, but Shelton’s response to a question about the size of the fleet raised more questions than it answered.

James Cameron Descends To The Bottom Of The Mariana Trench -- The Telegraph

James Cameron, the multi-millionaire Hollywood film director behind Titanic and Avatar, is heading to the bottom of the Mariana Trench in person armed with hi-tech 3D cameras and lights that will capture the moment for cinemagoers.

Fewer people have reached the deepest point in the world's oceans than have walked on the moon, but the obscure worms and tiny crustaceans that reside there are receiving an unlikely visitor.

Cameron set out from the tiny Pacific island of Guam for the Mariana Trench, and is descending more than seven miles straight down in a lime green reinforced submersible, the first ever solo mission to the lowest point on Earth.

Cameron’s 24ft long vertical capsule, The Deepsea Challenger, weighs 11 tons and was built amid great secrecy in Australia over the last eight years.

Red Meat Halves Risk Of Depression -- The Telegraph

Women who reduce lamb and beef in their diets are more likely to suffer depression, according to the new study.

Experts admitted surprise at the findings because so many other studies have linked red meat to physical health risks.

The team made the link after a study of 1000 Australian women.

Professor Felice Jacka, who led the research by Deakin University, Victoria, said: "We had originally thought that red meat might not be good for mental health but it turns out that it actually may be quite important.

Why Taking A Vacation Is Good For You


The Benefits Of Taking Time Off -- US News And World Report/Inside Science

Taking a vacation may not only make you happy, but increase your job performance.

(ISNS)—Rae and Bruce Hostetler not only work very hard, they also relax just as well. Numerous vacations help the suburban Indianapolis couple to maintain their health and emotional well-being—and it's no surprise to health care professionals.

"Rest, relaxation, and stress reduction are very important for people's well-being and health. This can be accomplished through daily activities, such as exercise and meditation, but vacation is an important part of this as well," said primary care physician Natasha Withers from One Medical Group in New York. Withers lists a decreased risk of heart disease and improved reaction times as some of the benefits from taking some time off.

"We also know that the mind is very powerful and can help with healing, so a rested, relaxed mind is able to help the body heal better," said Withers.

NSA Chief Denies To Congress That They Are Conducting Domestic Spying

NSA Chief Denies Domestic Spying But Whistleblowers Say Otherwise -- Threat Level

In a rare break from the NSA’s tradition of listening but not speaking, NSA chief General Keith Alexander was grilled Tuesday on the topic of eavesdropping on Americans in front of a House subcommittee.

The questioning from Rep. Hank Johnson (D-Georgia) was prompted by Wired’s cover story this month on the NSA’s growing reach and capabilities, but leaves Americans with as many questions about the reach of spy agency’s powers as they had before Alexander spoke.

Alexander denied, in carefully parsed words, that the NSA has the power to monitor Americans’ communications without getting a court warrant.

My Comment: The NSA chief is very careful with his words .... it appears that he has his own definition of spying and eavesdropping.

The Titanic As You've Never Seen It Before

The Titanic As You've Never Seen It Before: A Century After It Sank, Stunning New Hi-Tech Images Reveal Doomed Ship On Ocean Floor -- Daily Mail

The sinking of the Titanic is one of the 20th century's great dramas, a mystery that has confounded scientists and historians for decades.

There is still an aura of mysticism that remains around that fateful ship and new photos that will be published in the April 2012 edition of National Geographic Magazine provides for the first time a sense of what the wreck looks like today.

These new photographs, shot using state-of-the-art technology by independent research group Woods Hole Oceanographic Institution, provide a greater understanding of what happened on that fateful April 15, 1912.

Navy Opens 'Hunger Games' Arena For Military Robots -- Live Science

A new U.S. Navy lab can track every movement of battlefield robots as they struggle to survive arenas built to resemble scorching deserts, wave-pounded shores and tropical rain forests.

The lab's biggest environment has high-speed video cameras that automatically swivel to follow up to 50 ground robots, flying drones and even human soldiers. Such intense surveillance of man-made survival settings may remind science fiction readers of "The Hunger Games" — a popular book series turned Hollywood film(s) where "game makers" construct huge, naturalistic arenas to feature reality television displays of battles to the death.

How Quake-Prone Is The Mexico?



Mexico Earthquake: How Quake-Prone Is The Region? -- Christian Science Monitor

Mexico earthquake history shows that the same faults that caused Tuesday's Mexico earthquake can produce even bigger events, like one that struck in 1985.

Authorities in Mexico are surveying that damage following a magnitude 7.4 quake that struck the country just after noon on Tuesday local time.

The quake was centered some 31 miles north-northeast of the city of Ometepec, in a mountainous region dotted with villages. The rupture occurred at a depth of about 12 miles, according to estimates from the US Geological Survey's Earthquake Information Center in Golden, Colo.

Here Comes The U.S. Navy's Robot Jellyfish



Robotic Jellyfish Fuelled By Hydrogen Invented -- BBC

Engineers in the US say they have invented a hydrogen-powered robot that moves through water like a jellyfish.

Development of the robot, nicknamed Robojelly, is in the early stages but researchers hope it could eventually be used in underwater rescue operations.

Writing in Smart Materials and Structures, Yonas Tadesse said the jellyfish's simple swimming action made it an ideal model for a vehicle.

Being fuelled by hydrogen means, in theory, it will not run out of energy.

Mr Tadesse, the lead author of the study, said: "To our knowledge, this is the first successful powering of an underwater robot using external hydrogen as a fuel source."

Illegal Logging Makes Billions For Gangs, Report Says -- BBC

Illegal logging generates $10-15bn (£7.5-11bn) around the world, according to new analysis from the World Bank.

Its report, Justice for Forests, says that most illegal logging operations are run by organised crime, and much of the profit goes to corrupt officials.

Countries affected include Indonesia, Madagascar and several in West Africa.

The bank says that pursuing loggers through the criminal justice system has made a major impact in some nations, and urges others to do the same.

Females Achieve Sexual Pleasure And Orgasm By Working Out


Females Achieve Orgasm and Sexual Pleasure By Working Out -- Sci-Tech Daily

It looks like time at the gym may be more satisfying for women than a hot date. A new study from the University of Indiana confirms that women can achieve an orgasm, often called “coregasm,” simply by working out.

While not unheard of, reports of “coregasm” have circulated in the media for years, these are the first confirmed findings authored by Debby Herbenick, co-director of the Center for Sexual Health Promotion in Indiana University’s School of Health, Physical Education and Recreation and J. Dennis Fortenberry, M.D., professor at the Indiana University School of Medicine and Center for Sexual Health Promotion affiliate. The findings are published in a special issue of Sexual and Relationship Therapy.

Neuroscience, Ethics, And National Security: The State Of The Art -- Kurzweilai

U.S. military and intelligence communities fund and utilize an array of neuroscience applications, generating profound ethical issues, say researchers from Wake Forest University and theUniversity of Pennsylvania.

Neuroscience offers possibilities for cutting edge, deployable solutions for the needs of national security and defence, but are, or at least should be, tempered by questions of scientific validity, consequential ethical considerations, and concern for the relationship between science and security, according to the researchers.

Military-Funded Brain Science Sparks Controversy -- Live Science

Brain research and associated advances such as brain-machine interfaces that are funded by the U.S. military and intelligence communities raise profound ethical concerns, caution researchers who cite the potentially lethal applications of such work and other consequences.

Rapid advances in neuroscience made over the last decade have many dual-use applications of both military and civilian interest. Researchers who receive military funding — with the U.S. Department of Defense spending more than $350 million on neuroscience in 2011 — may not fully realize how dangerous their work might be, say scientists in an essay published online today (March 20) in the open-access journal PLoS Biology.
