Jamestown settlers resorted to cannibalism, skeleton reveals

Facing starvation, Jamestown colonists resorted to consuming the flesh of a deceased 14-year-old girl, reveals an analysis of remains found at America's first permanent English settlement.?

Born about 1595, Jane hailed from England's southern coast. She was likely the daughter of a gentleman, and her ship to the Americas likely arrived at?James Fort?in August 1609. It turned out to be one of the worst possible times to land at?the New World's first permanent English settlement.?

Jane died that year, or possibly early the following year, and her flesh was eaten by her fellow settlers to fend off starvation.

These are the conclusions of those who examined Jane's bones, which represent the first physical evidence of cannibalism in Colonial America.?

What would later become the Jamestown settlement was founded two years earlier, in 1607. In many respects, the site chosen by?Captain Edward Maria Wingfield, who led the 104 settlers, was ideal. It was surrounded by three sides by navigable water and was a perfect defensive location. Most importantly, the spot was not inhabited by native Americans. ?

But there was a reason the Indians avoided the site: The land was swampy and unsuited for agriculture, the water brackish and undrinkable, and the air buzzing with mosquitoes. In any case, the settlers arrived too late to plant crops. Within a nine months, almost two thirds of the colonists had died.?

Hundreds more settlers arrived at James Fort, as it was called then, and that meant more mouths to feed. Relations between the colonists and the?Powhatan Indians, initially friendly, turned sour, and the natives laid siege to the settlement, trapping the colonists inside.?

The years 1609 and 1610 were known as the "starving time." Of the 500 colonists, only 61 survived.

George Percy, who led the settlers during the starving time, would later describe the desperation:?

Now all of us att James Towne beginneinge to feele the sharpe pricke of?hunger w[hi]ch noe man trewly descrybe butt he w[hi]ch hathe Tasted the?bitternesse thereof. A worlde of miseries ensewed as the Sequell will expresse?unto yow, in so mutche thatt some to satisfye their hunger have Robbed the?store for the w[hi]ch I Caused them to be executed. Then haveinge fedd?upour horses and other beastes as longe as they Lasted, we weare gladd to?make shifte w[i]th vermin as doggs Catts Ratts and myce all was fishe thatt?Came to Nett to satisfye Crewell hunger, as to eate Bootes shoes or any?other leather some Colde come by and those beinge Spente and devoured?some weare inforced to searche the woodes and to feede upon Serpentts and?snakes and to digge the earthe for wylde and unknowne Rootes, where many?of our men weare Cutt of and slayne by the Salvages. And now famin?beginneinge to Looke gastely and pale in every face, thatt notheinge was?Spared to mainteyne Lyfe and to doe those things w[hi]ch seame incredible,?as to digge upp deade corpes outt of graves and to eate them.

Many historians doubted Percy's accounts of cannibalism, but those doubts are now dispelled. The bones of Jane ? a name the researchers have given to the girl whose identity is unknown ? were spotted in?a refuse pit along with the skeletal remains of butchered horses and dogs?by a team of archaeologists led by William Kelso of Preservation Virginia.

"Our team has discovered partial human remains before, but the location of the discovery, visible damage to the skull and marks on the bones immediately made us realize this finding was unusual," said Dr. Kelso in a press release.

Jane's remains were analyzed by Douglas Owsley, a physical anthropologist at the Smithsonian's National Museum of Natural History in Washington, who concluded, based on the cut marks on her skull and shinbone, that someone had stripped the meat from her bones.

"These people were in dire circumstances. So any flesh that was available would have been used," Dr. Owsley said?in an interview with Smithsonian Magazine, which broke the story on Wednesday. "The person that was doing this was not experienced and did not know how to butcher an animal. Instead, we see hesitancy, trial, tentativeness and a total lack of experience."

Owsley would know, having?analyzed many cannibalized remains from ancient history, as well as those of the first victim of Jeffrey Dahmer.

He doubts that Jane was murdered for food, however.??I don?t think that they killed her, by any stretch,? he told Smithsonian. ?It's just that they were so desperate, and so hard-pressed, that out of necessity this is what they resorted to.?

Jane's bones revealed other clues about her life. Her molars and the joint below her knee indicated her age, about 14 years old. Isotopes revealed a diet of English rye and barley, and plenty of meat, suggesting an upper-class background. Oxygen molecules indicate an English upbringing near the sea.?

Using a reproduction of her skull as a model, experts have reconstructed a bust of Jane, which will be on display as part of a new exhibition at Historic Jamestowne, which opens Friday.?

"The 'starving time' was brought about by a trifecta of disasters: disease, a serious shortage of provisions, and a full scale siege by the Powhatans that cut off Jamestown from outside relief," said Jamestown expert Jim Horn, in a press release. "Survival cannibalism was a last resort; a desperate means of prolonging life at a time when the settlement teetered on the brink of extinction."

NASA measures rainfall as Cyclone Zane approaches Queensland, Australia

NASA measures rainfall as Cyclone Zane approaches Queensland, Australia [ Back to EurekAlert! ] Public release date: 2-May-2013

NASA's Tropical Rainfall Measuring Mission or TRMM satellite passed over Cyclone Zane as it was approaching Queensland Australia's Cape York Peninsula and measured rainfall rates within the storm. TRMM data showed a disorganized storm with the strongest rain falling northwest of the center.

Cyclone Zane, as of 12:00 UTC (10:00 p.m. Australian Eastern Standard Time or AEST) on May 1, 2013, was located about 215 km (~133 miles) due east of the coast of Queensland, Australia.

NASA's TRMM satellite captured an image of Cyclone Zane at 11:48 UTC (9:48 p.m. AEST/7:48 a.m. EDT, U.S.) May 1, 2013. At the time, the center of circulation was located about 215 km (~133 miles) due east of the coast of Queensland, Australia and was heading west-northwest. TRMM revealed that Zane was still not very well organized with no eye visible and very little evidence of banding (curvature) in the rain area. At the time of the image, Zane was a Category 1 cyclone (equivalent to a tropical storm on the U.S. Saffir-Simpson scale) with sustained winds reported at 45 knots (~52 mph) by the Australian Bureau of Meteorology's Tropical Cyclone Warning Centre. Most of the rainfall that TRMM measured was light to moderate within Cyclone Zane, with the exception of an area northwest of the center that had a rainfall rate of around 2 inches/50 mm per hour.

The TRMM data was also made into a 3-D image that showed the cloud heights relative to the rainfall rates occurring in Zane. The image was created at NASA's Goddard Space Flight Center in Greenbelt, Md. and showed that although Zane had an area of active deep convection reaching upwards of 15 km (about 9.2 miles), it was located away from the center of circulation and does not necessarily preclude further strengthening. In fact, Zane weakened further.

By May 1 at 2100 UTC (5 p.m. EDT, U.S.), the Joint Typhoon Warning Center issued their final bulletin on Cyclone Zane. At that time Zane's maximum sustained winds were near 35 knots (40 mph/64 kph) and weakening. Zane was located about 270 nautical miles north-northwest of Cairns, Australia and was moving to the northwest at 10 knots (11.5 mph/18.5 kph).

Zane is expected to weaken due to unfavorable wind shear before crossing the coast of northern Queensland north of the Lockart River and dissipate shortly afterward.

Schwab, one of the largest U.S. brokerages, said on Tuesday afternoon it was that target of a distributed denial of service attack - an attack that floods websites with traffic in order to block access - that left clients unable to trade through the site for two hours.

Phone service was available during both attacks, although responses were slower than usual due to the large number of people calling in, said Schwab spokesman Greg Gable.

He said clients who believe they were affected by the outage can call 1-800-435-4000 to talk with a Schwab representative.

The attacks did not impact client data or accounts, Gable added.

Schwab said it is actively investigating the attacks but could not provide further information.

The San Francisco-based company had 8.9 million active brokerage accounts and $2.1 trillion in total client assets at the end of the last quarter.

Corporate pension funding down in 2012 on falling interest rates

By Manuela Badawy

NEW YORK (Reuters) - The funding shortfall bedeviling the 100 largest U.S. corporate pension funds rose for a second straight year in 2012, as a strong stock market and hefty plan contributions failed to offset damage done by persistently low interest rates, according to an analysis by Towers Watson released on Monday.

The gap between what these corporations, all publicly traded, will owe retired workers and how much they have put aside jumped 17 percent, from $252.7 billion at year-end 2011 to $295.2 billion at year-end 2012. By comparison, these companies had a pension surplus of $86 billion in 2007.

Companies are required to calculate the present value of the future pension liabilities by using a so-called discount rate, based on corporate bond yields. As those rates fall, the liabilities rise.

An unprecedented level of lump sum buyouts and annuity purchases partially offset the increases in both assets and liabilities - due to lower interest rates. Without the buyouts and annuity purchases, obligations would have increased by 12 percent.

Since the 2008 financial crisis, corporate pension plan assets have increased, owing to the double-digit gains in stock markets and large contributions. The Standard & Poor's 500 Index climbed more than 13 percent in 2012.

"However, four consecutive years of declining interest rates pushed liabilities 40 percent higher, leaving companies with larger deficits than before," said Alan Glickstein, a senior consultant at Towers Watson.

According to the Towers analysis, employers contributed $45.1 billion to their pension plans in 2012. That is a 16 percent increase from 2011 and the largest contribution employers have made in the past five years. The analysis noted that the companies contributed more than twice the amount of benefits accrued last year to keep funding levels up.

Over the last few years many corporations have been gradually adjusting their portfolios to reduce investment risk relative to liabilities, shifting from public equities to fixed-income and alternative investments.

Since 2009, average allocations to equities have fallen 10 percentage points, while allocations to fixed-income investments have risen by eight percentage points. However, the shift away from equities slowed in 2012, according to the report.

"Of the 95 companies that reported target asset allocation strategies for 2012 and 2013, only three reduced their target equity allocations by 10 percent or more, versus 16 for 2011," Towers Watson's report said.

"Obviously, there is a long way to go until the end of the year, but funding ratios are moving in the right direction," said Dave Suchsland, a senior consultant at Towers Watson.

"If interest rates don't continue their rise and equity returns weaken, plan sponsors may need to pour more cash into their plans to improve funded status for the full year."

Humans feel empathy for robots: fMRI scans show similar brain function when robots are treated the same as humans

Apr. 23, 2013 ? From the T-101 to Data from Star Trek, humans have been presented with the fictional dilemma of how we empathize with robots. Robots now infiltrate our lives, toys like Furbies or robot vacuum cleaners bring us closer, but how do we really feel about these non-sentient objects on a human level? A recent study by researchers at the University of Duisburg Essen in Germany found that humans have similar brain function when shown images of affection and violence being inflicted on robots and humans.

Astrid Rosenthal-von der P?tten, Nicole Kr?mer, and Matthias Brand of the University of Duisburg Essen, will present their findings at the 63rd Annual International Communication Association conference in London. Rosenthal-von der P?tten, Kr?mer and Brand conducted two studies. In the first study, 40 participants watched videos of a small dinosaur-shaped robot that was treated in an affectionate or a violent way and measured their level of physiological arousal and asked for their emotional state directly after the videos. Participants reported to feel more negative watching the robot being abused and showed higher arousal during the negative video.

The second study conducted in collaboration with the Erwin L. Hahn Institute for Magnetic Resonance Imaging in Essen, used functional magnetic-resonance imaging (fMRI), to investigate potential brain correlations of human-robot interaction in contrast to human-human interaction. The 14 participants were presented videos showing a human, a robot and an inanimate object, again being treated in either an affectionate or in a violent way. Affectionate interaction towards both, the robot and the human, resulted in similar neural activation patterns in classic limbic structures, indicating that they elicit similar emotional reactions. However, when comparing only the videos showing abusive behavior differences in neural activity suggested that participants show more negative empathetic concern for the human in the abuse condition.

A great deal of research in the field of human-robot interaction concentrates on the implementation of emotion models in robotic systems. These studies test implementations with regard to their believability and naturalness, their positive influence on participants, or enjoyment of the interaction. But there is little known on how people perceive "robotic" emotion and whether they react emotionally towards robots. People often have problems verbalizing their emotional state or find it strange to report on their emotions in human-robot interactions. Rosenthal-von der P?tten and Kr?mer's study utilized more objective measures linked to emotion like physiological arousal and brain activity associated with emotional processing.

"One goal of current robotics research is to develop robotic companions that establish a long-term relationship with a human user, because robot companions can be useful and beneficial tools. They could assist elderly people in daily tasks and enable them to live longer autonomously in their homes, help disabled people in their environments, or keep patients engaged during the rehabilitation process," said Rosenthal-von der P?tten. "A common problem is that a new technology is exciting at the beginning, but this effect wears off especially when it comes to tasks like boring and repetitive exercise in rehabilitation. The development and implementation of uniquely humanlike abilities in robots like theory of mind, emotion and empathy is considered to have the potential to solve this dilemma."

"Investigation on Empathy Towards Humans and Robots Using Psychophysiological Measures and fMRI," by Astrid Rosenthal-von der P?tten and Nicole Kr?mer; To be presented at the 63rd Annual International Communication Association Conference, London, England 17-21 June.
