Pandora's Promise: Director Robert Stone Takes On The Anti-Nuclear Movement

Science2.0 - June 14, 2013 - 10:28pm
Do you like nuclear weapons?

If you respond yes to that, I think you have lost your mind. While I understand the value of an overwhelming force to end a bloody world war, it's also something that can't be unmade.  We had opened "Pandora's Box", the belief went.

Gene Patents: Justice Scalia Dissents On High School Science

Science2.0 - June 14, 2013 - 9:28pm
The U.S. Supreme Court just released a groundbreaking decision about the ability to patent genes – the assembly instruction for life.  

Amid much discussion about potential implications for the biotech industry, a separate, extremely troubling aspect of this decision has largely slid under the radar: one of the SCOTUS Justices dissented with basic science saying he is "unable to affirm... knowledge or even my own belief" in high school biology

Around The Arctic June 2013


The Arctic is currently primed for rapid and extensive ice loss, unless we see some very unusual weather conditions this Summer.

The state of the ice can be seen in the following series of satellite images from NASA's Earth Observing System Data and Information System - EOSDIS.  EOSDIS produces near real-time data and makes images such as the Arctic mosaic and the Near Real Time (Orbit Swath) Images available on the web.

Biological Costs

Science2.0 - June 14, 2013 - 1:15am
In several posts the question of biological costs is invariably mentioned in discussing evolution.  These costs are normally of the metabolic or fitness type.  Metabolic costs are associated with the existence of a particular trait and the energy necessary for the trait's existence, while fitness costs are those that have an impact on the organism's ability to survive and reproduce (1).

In most instances, these concepts are taken from economic analogies, yet, like economics, the concept of cost is meaningless without a context.  The two defining elements that must be considered are value and affordability.

'Spiritual But Not Religous'? Don't Trust Them

Science2.0 - June 13, 2013 - 10:30pm

In the last two generations, the designation 'spiritual but not religious' has become popular. It's hard to know what it means - atheists and religious people are at least taking some sort of stand - but one thing sociologists say they do know: Young adults who deem themselves "spiritual but not religious" are more likely to commit both violent and property crimes than young people who self-report religious belief ("religious and spiritual" or "religious but not spiritual").

Parasites Get No Respect In Food Web Theory?

Science2.0 - June 13, 2013 - 9:31pm

Parasites comprise a large proportion of the diversity of species in every ecosystem but they are rarely included in analyses or models of food webs.  Would it make a difference?

A new paper says that
including parasites does alter the structure of food webs, but that most changes occur because of an increase in diversity and complexity, rather than from unique characteristics of parasites.

Lone Signal: METI Teams Up With Citizen Science To Try And Make First Contact

Science2.0 - June 13, 2013 - 7:37pm
If you want to make sure your extra-terrestrial efforts can survive a nuclear attack, working inside the Jamesburg Earth Station on, fittingly, ComSat Road, just outside Carmel, California, is a fine choice. A short drive to Pebble Beach and Spyglass golf courses means it is not a bad way to spend your weekends either.

If you enjoyed seeing Neil Armstrong walking on the Moon, Jamesburg is one of the dishes you can thank. But the 10-story high antenna went out of service in 2002. The land was sold to a gentleman who wanted a vacation home - the coolest Cold War vacation home ever, if you ask me, with blueprints and cinder block walls and a room the size of a football field.

METI: Should We Be Shouting At The Cosmos?

Science2.0 - June 13, 2013 - 7:19pm
David Brin first wrote this in 2006, summarizing a controversy that was then emerging among members of the community engaged in SETI, the Search for Extra-Terrestrial Intelligent civilizations. Since I am covering a new effort at METI - Messaging Extra-Terrestrial Intelligent civilizations - going online next week, he sent me this in our email exchanges and agreed to repost it here and provide a follow-up addendum at the end - Hank -->

Like World War Z Or Justin Bieber? Thank Evolution

Science2.0 - June 13, 2013 - 6:06pm

If you watch musicals from the 1950s or teen comedies from the 1990s, you find a lot of movies with different titles but the themes and plotlines barely change; two friends competing for a girl in the former or some teen wants to improve another teen, who becomes really popular, in the latter.

It's not that Hollywood lacks imagination, we are naturally drawn toward a specific set of universal narratives within cultural products, says a new paper. We have evolved to like stories about Superman saving strangers or Brad Pitt fighting zombies.

Preparing For The Next Megathrust Earthquake

Science2.0 - June 13, 2013 - 5:31pm

In the past 11,00 years, there have been 22 large and megathrust earthquake shaking events along the Pacific coast of North America, an average recurrence interval of about 500 years, though the time between major shaking events can stretch up to about 1,000 years, according to a new paper.

'Dinobird' Plumage Patterns Revealed By X-Rays

Science2.0 - June 13, 2013 - 3:46pm

X-ray experiments have found chemical traces of the original 'dinobird' Archaeopteryx and dilute traces of plumage pigments in a 150 million-year-old fossil.

Only 11 specimens of Archaeopteryx have been found, the first one consisting of a single feather. Until a few years ago, researchers thought minerals would have replaced all the bones and tissues of the original animal during fossilization, leaving no chemical traces behind, but two studies have turned up more information about this 'dinobird' and its plumage.

Do Green Coffee Bean Weight Loss Supplements Work?

Science2.0 - June 12, 2013 - 4:56pm

A trending "miracle" weight-loss product is green coffee bean dietary supplements. Some people swear by them and marketing claims are not modest about the effectiveness.

But do they actually work or is it placebo and/or other changes (exercise, diet) that concerned people adapt?

Science would never criticize coffee. It is rich in healthful, natural, plant-based polyphenol substances and evidence from past studies links coffee drinking to a lower risk of obesity, high blood pressure, type 2 diabetes and other disorders collectively termed the "metabolic syndrome."  Chlorogenic acid (CGA), one coffee polyphenol, is the main ingredient in scores of dietary supplements promoted as weight-loss products.

Glacier Changes in NE Greenland


Substantial cracks in the Nioghalvfjerdsfjorden glacier ice tongue appear to be growing in extent and number.  While not as spectacular as the 2010 calving of the Peterman Ice Island, it is more closely linked to global warming than

Otherwise known as 79 North, Nioghalvfjerdsfjorden glacier is a floating outlet glacier, about 60 km long and 20 km wide located at 79°30'N, 22° W, draining a large area of the northeast Greenland ice sheet.

Got The Gout, Ebenezer? Don't Blame Your Big Toe

Science2.0 - June 11, 2013 - 11:38pm

Gout is a painful rheumatic condition. It occurs when uric acid, a bodily waste product, crystallizes in joints and soft tissues. Gout is often associated with the big toe, but that turns out to be unfair; patients at highest risk of further flare-ups are those whose gout first involved other joints, such as a knee or elbow, according to new research.

Rule Change May Not Save Dying Child, But You Could

Science2.0 - June 11, 2013 - 7:24pm

Deciding who gets a lung transplant - and thereby who doesn’t - is not easy.  Lungs can only be transplanted from people who are organ donors, who are brain dead, and who died in such a way that their organs remain intact.  Problem is, there are not enough people marking the “organ donor” box on their driver’s license to give everyone on the transplant list a chance to live.

Comparison Of Multi-Variate Discriminants

Science2.0 - June 11, 2013 - 5:15pm
The problem of classifying elements of a data set as belonging to one class or another, depending on their characteristics, is a very, very well-studied one, and one which is particularly important in particle physics.

Imagine, for instance, that you collect events with four high-transverse-momentum leptons (electrons or muons) with the ATLAS or CMS detector, and you wish to sort out which of these fit better to the hypothesis of being originated by Higgs boson decay into two Z bosons (with each Z boson in turn producing a lepton pair) rather than to the alternative hypothesis of being due to the incoherent production of a pair of Z bosons -a process that has nothing to do with Higgs bosons. This means you need to classify the data events using their observed features. -->
