The Surfing Is Great On Titan This Time Of Year

May 25, 2013 - 5:39pm
Saturn's moon Titan might be in for some wild weather as it heads into its spring and summer, if two new models are correct.

Scientists think that as the seasons change in Titan's northern hemisphere, waves could ripple across the moon's hydrocarbon seas, and hurricanes could begin to swirl over these areas, too. The model predicting waves tries to explain data from the moon obtained so far by NASA's Cassini spacecraft. Both models help mission team members plan when and where to look for unusual atmospheric disturbances as Titan summer approaches.

Lightning

May 24, 2013 - 10:39pm
I recently read an article about an individual that had been struck by lightning, while it was interesting to read about the experience it was disturbing to read some of the comments that followed and their gross misunderstanding of lightning.

In particular the following comment illustrates the problem.
Lightning happens when a really huge negative charge builds up in the ground, corresponding to a positive charge overhead, and the differential becomes sufficient to jump the gap. (and, as others are pointing out repeatedly, air is an excellent insulator, so it takes a whacking huge voltage differential to make the arc.)

How The Immune System Tolerate A Healthy Gut Flora

May 24, 2013 - 9:15pm
The human intestinal tract is the home of a diverse array of bacterial colonies, settling in as soon as their host begins life. While these colonies were considered to merely coexist with the host for their own survival, decades of study have shown the interaction between bacteria and host is mutually beneficial.  The bacterial colonies benefit by finding their home in the host, while the host benefits from the bacteria’s ability to keep the intestinal tract healthy, specifically by aiding in the absorption of nutrients, and by preventing disease-causing bacteria from taking root. -->

Atheists In Foxholes? Not Many - And Less The More Soldiers Dislike War

May 24, 2013 - 7:16pm

Ernie Pyle, the iconic embedded World War II embedded journalist killed by Japanese machine gun fire in 1945, made famous the adage, "There are no atheists in foxholes." 

He was making a point that it's better to be safe than sorry when your life is on the line - not letting the Devil get you cornered, he wrote, was the justification for a soldier who dug round foxholes. Atheists are a tiny minority anyway and there are even fewer in a war zone, Pyle felt. And he knew more soldiers than perhaps any journalist ever will.

The Importance Of The Literature

May 24, 2013 - 5:40pm
The Importance Of The Literature

The public at large, and unfortunately too many writers, do not know how vital a properly conducted survey of the scientific literature can be.  We must remember the motto of the Royal Society - nullius in verba - do not rely on anybody's word.  If the mythical "everybody" is stating the same "fact" or citing exactly the same source: question it.  Reappraise it.  Investigate.

This article was inspired by Hontas Farmer's newest blog.  It occurred to me that I spend many a happy hour doing literature research but I do not write about it as such.

ATLAS Vs CMS Higgs Results: Which Experiment Has More Sensitivity ?

May 24, 2013 - 3:47pm
"Oh Wind, if Winter comes, can Spring be far behind ?"

Good old Shelley inspired me to start today's article with the above verse, taken from his magnificent "Ode to the West Wind". With the weather we are experiencing these days in Geneva and northern Italy, I found it a relieving thought...

So, winter conferences are over, and summer ones are still far away. This is therefore a nice moment to try an assessment on the quality of the results that the two competing CERN experiments have produced on the study of the Higgs boson. Why ? Because we are not going to have to change our conclusions in a short time scale caused by a result about to be published.

Does Tourism Revenue Help Birds In Protected Areas?

May 23, 2013 - 10:07pm

How much does tourism help fund bird conservation? Given the continuing boom of the "avitourism" industry, this sounds like the sort of question to which both environmentalists and entrepreneurs should know the answer.

However, while researchers have performed calculations investigating the availability of tourism revenues for mammal and frog conservation efforts, nobody has explored similar trends in other taxa--or, to be more accurate, nobody had explored those trends until a group of Australian scientists recently decided to crunch the relevant numbers.

The results of their analyses were reported earlier this month in PLoS ONE.

The Power Of Evolutionary Theory

May 23, 2013 - 6:05pm
As has been mentioned in other articles, evolution is one of the more misunderstood theories ‌in biology.  This isn't because it is complicated.  Its beauty derives from its simplicity, but often the nuances that are overlooked.  

We hear about "survival of the fittest" and many immediately think of strength.  We hear about natural selection and many immediately focus on speciation.  Yet, the first claim is simply wrong, while the second isn't the most important element of the theory.

So, if it's not about strength or how species originated, then what is important.

Helmet Laws, Not Parental Concern, Have Led To Reduced Fatalities In Bicycle-Car Collisions

May 23, 2013 - 10:30am

A 12-year study (1999 to 2010) analyzed fatality reductions in bicycle-car collisions to determine the effect of mandatory helmet laws. 16 states had bike helmet laws in the beginning or the study. The researchers identified all relevant fatalities, totaling 1612, in states with and without bike helmet laws.
  

Relevance was determined by adjusting for factors previously associated with rates of motor vehicle fatalities (elderly driver licensure laws, legal blood alcohol limit and household income) and, among those, they found that the adjusted fatality rate was significantly lower in states with helmet laws. On average, 900 people die annually in bicycle-motor vehicle collisions — three quarters of those are from head injuries.

Gorillas And The Future Of Crop Biotechnology

May 22, 2013 - 11:16pm

There are some really cool improvements coming along in several crops that have been developed using the tools of biotechnology - GMOs if you will.

Some of these innovations have consumer health benefits. Some expand ways to encourage greater produce consumption. Some reduce food waste. Some prevent crop losses through disease and reduce the need for copper sprays.

These traits represent an expansion of biotech beyond the major row crops primarily grown for animal feed or for fiber to crops like apples, oranges, tomatoes, pineapples and potatoes. Whether these new options actually make it to consumers depends a great deal on decisions that will be made by gorillas.

Could Roadways Actually Be Good For Wildlife?

May 22, 2013 - 9:42pm

You might interpret roadkill as a sign that highways are bad for wildlife, but it's possible these carcasses actually indicate that roadsides are attractive habitats that can support a large number of individuals. That's one interpretation, anyway, of a new study investigating small mammal populations living along highways in central Spain.

Kentucky Windage, For Science: Using Black Holes To Measure The Universe's Rate Of Expansion

May 22, 2013 - 8:01pm

Calibration does not always mean fixing a device, it sometimes means adjusting to solve a problem.  In the early years of America, the famous Kentucky longrifles that conquered the frontier (and some British) had fixed sights. Since they couldn't be adjusted, frontiersmen - Kentucky was part of "The West" then - would adjust for wind, elevation and range by experience.  If their shot was hitting low and left, they aimed high and right. Inference helped them get a better result.

Saffron


In one of my school history books, as I remember, there is a story that saffron was introduced into Europe by a pilgrim from concealing some corms in his staff, to avoid the death penalty if found by the agents of the Sultans who controlled its export.  However, the history of saffron, including a 14-week ‘saffron war’, seems much more complicated that this.

High Fructose Corn Syrup Addictive Like Cocaine, Says Researcher

May 22, 2013 - 2:52pm

Is the obesity epidemic due to the addictive qualities in food or that a lot more food is cheap and plentiful than ever before in history?

A paper presented at the 2013 Canadian Neuroscience Meeting, the annual meeting of the Canadian Association for Neuroscience - Association Canadienne des Neurosciences (CAN-ACN), says the problem is addiction rather than food wealth - the authors claim that high-fructose corn syrup can cause behavioral reactions in rats similar to those produced by drugs of abuse such as cocaine.  It's the "Food Addiction" hypothesis that has recently become popular, which posits that we could be addicted to food just like drugs.

Magnetism Makes Archaeological Sourcing 'High Definition'

May 22, 2013 - 2:19pm

Sourcing of ancient artifacts has gotten a new advance.

While at the University of Sheffield in the years 1965–1972, Professor Lord Colin Renfrew developed a technique that matched stone tools made of obsidian, naturally occurring glass, to their volcanic origins based on their chemical fingerprints. It was considered one of the greatest successes in scientific archeology, matching artifacts to specific volcanoes was a significant leap forward in understanding trade, contact, and cultural change in the ancient world.
