Mysterious Stone Spheres In Costa Rica Investigated

John Hoopes, University of Kansas associate professor of anthropology and director of the Global Indigenous Nations Studies Program, recently returned from a trip to Costa Rica where he and colleagues evaluated ancient stone spheres for UNESCO, the United Nations cultural organization that might grant the spheres World Heritage Status.

From Science Daily:

Science Daily (Mar. 23, 2010) — The ancient stone spheres of Costa Rica were made world-famous by the opening sequence of "Raiders of the Lost Ark," when a mockup of one of the mysterious relics nearly crushed Indiana Jones.

So perhaps John Hoopes is the closest thing at the University of Kansas to the movie action hero.

How The Tablet Will Change The World

From Wired:

Everyone who jammed into the Yerba Buena Center for the Arts in San Francisco on January 27, 2010, knew what they were there for: Apple CEO Steve Jobs’ introduction of a thin, always-on tablet device that would let people browse the Web, read books, send email, watch movies, and play games. It was also no surprise that the 1.5-pound iPad resembled an iPhone, right down to the single black button nestled below the bright 10-inch screen. But about an hour into the presentation, Apple showed something unexpected — something that not many people even noticed.

How Science Is Countering Biological And Chemical Threats

Bio-terror A versatile material that neutralizes a range of biological and chemical agents could save time and lives in the event of a terrorist attack or accident.

New Versatile Polymer Counters Both Chemical and Biological Threats -- Popular Science

Because terrorists rarely announce the technical details of their nefarious intentions beforehand, the threat posed by weapons of mass destruction is not only great, it's multifaceted. So a team from the McGowan Institute of Regenerative Medicine has synthesized a polyurethane fiber mesh that is as variable as the terrorist threat. By mimicking biological tissues like the skin that respond to shifting environments, the a multifunctional polymer can decontaminate a range of both biological agents and chemical toxins.

Loneliness Increases Your Blood Pressure

From The Telegraph:

Loneliness can increase blood pressure if you are over 50, according to a new university study.

Lack of connection with others not only makes us unhappy but it is also bad for the wellbeing of your body, research finds.

The psychologists found that there is a direct relation between loneliness and larger increases in blood pressure four years later—a link that is independent of age and other factors such as smoking and obesity.

Arctic Winds And Not Global Warming 'Responsible For Much Of Record Loss Of Sea Ice'

Study: Strong winds and not global warming are to blame for much of the record-breaking loss of ice in the Arctic Ocean in recent years.

From The Daily Mail:

Strong winds and not global warming are to blame for much of the record-breaking loss of ice in the Arctic Ocean in recent years, new research reveals.

Ice blown out of the Arctic area by winds can explain the one-third drop of sea ice since 1979, scientists believe.

The study helps to explain the huge loss of ice in the region during the summers of 2007 and 2008, after which some commentators suggested the Arctic Ocean would be ice-free during the summertime within a decade.

US Space Companies Present Soyuz-Busting Price Plans

Matching Russian rides to the International Space Station after the space shuttle retires will be difficult without "extraordinary" US government help, a senior NASA insider said on Thursday. But the private space firm SpaceX of Hawthorne, California, says it is ready to step into the breach by undercutting the current $50 million-per-astronaut round-trip ticket for travelling to the ISS aboard the Russian Soyuz craft.

Do Animals Commit Suicide? A Scientific Debate

From Time Magazine:

Forty years ago, Richard O'Barry watched Kathy, a dolphin in the 1960s television show Flipper, kill herself. Or so he says. She looked him in the eye, sank to the bottom of a steel tank and stopped breathing. The moment transformed the dolphin trainer into an animal-rights activist for life, and his role in The Cove, the Oscar-winning documentary about the dolphin-meat business in a small town in Japan, has transformed him into a celebrity.

"The suicide was what turned me around," says O'Barry. "The [animal entertainment] industry doesn't want people to think dolphins are capable of suicide, but these are self-aware creatures with a brain larger than a human brain. If life becomes so unbearable, they just don't take the next breath. It's suicide."

Large Hadron Collider To Start Hunt For 'God Particle'

Engineers have been installing a new protection system for the LHC's magnets

From The BBC:

The organisation that operates the Large Hadron Collider has set a date for the start of its science programme.

On Tuesday 30 March, engineers at Cern will make their first attempt to collide beams at an energy of 3.5 trillion electronvolts (TeV) per beam.

The LHC reached this beam energy last week, breaking its own particle beam energy record.

From Science Daily:

Science Daily (Mar. 23, 2010) — A shade more than 200 million years ago, the Earth looked far different than it does today. Most land on the planet was consolidated into one continent called Pangea. There was no Atlantic Ocean, and the rulers of the animal world were crurotarsans -- creatures closely related to modern crocodiles.

Portion Sizes in 'Last Supper' Paintings Grew Over Time

From Live Science:

Nutrition experts have analyzed the food depicted in some of the best-known paintings of the biblical Last Supper and found that the portion and plate sizes depicted in them increased substantially from older paintings to those painted more recently.

The findings suggest the trend of bigger plates and portions that has been noticed recently and linked to obesity may have been in the works for much longer, the researchers suggest.

Queen Chooses Which Sperm Die

From Cosmos:

SYDNEY: The queen of a social insect colony has one sexual encounter during her life, which involves many males, then controls which sperm will die off, researchers said.

A social insect queen only experiences a single day of sexual activity in her lifetime yet she must obtain all the sperm necessary to create an entire colony within that time frame. This means that social insect females store a large amount of sperm in their storage organ.

"A honeybee queen mates with many more males than she has to, thereby collecting much more sperm than she actually needs," said Boris Bear, from the University of Western Australia in Crawley.

Swiss Team Breaks Record for Around-the-World Flight, Despite Encountering Volcanic Eruption

From Popular Science:

First time the record has been set with refueling stops.

Piloting a plane older than two of the three crew on board, a Swiss team shattered Steve Fossett's around-the-world flight record by almost ten hours over the weekend, the first time the record has been set in this weight class with refueling stops. But the pilots didn't just have to negotiate the usual headwinds and bad weather -- their flight was nearly derailed by a volcanic eruption in Iceland that forced them to make an extra refueling stop and add an unexpected 12th leg to their journey.

Who Writes Wikipedia Articles?

From Discovery News:

Wikipedians who can perform a range of roles -- rather than possess a single expertise -- are key to quality articles.

It takes a village of contributors -- adding paragraphs here, inserting references there -- to craft a quality Wikipedia article, according to a new study that identifies the types of contributors who initiate and dominate the process to separate the Wikipedia wheat from chaff.

Ivory Bids Fall On Poaching Fears

The UN's wildlife trade organisations have turned down Tanzania's and Zambia's requests to sell ivory amid concern about elephant poaching.

The countries asked the Convention on International Trade in Endangered Species (CITES) meeting to permit one-off sales from government stockpiles.

The ivory trade was banned in 1989, but three sales have since been granted to nations showing effective conservation.
