A Growing America

A Growing America

“Adults who are obese now outnumber those who are merely overweight, according to a new report in the journal JAMA Internal Medicine.

A tally by researchers from Washington University School of Medicine in St. Louis estimated that 67.6 million Americans over the age of 25 were obese as of 2012, and an additional 65.2 million were overweight.”

Perfect Pizza Through Science!

October 8, 2014

Perfect Pizza Through Science!

Researchers at the University of Auckland (in partnership with Fonterra, the world’s largest dairy products exporter) used a machine to measure the integral elements of possible pizza ingredients as precisely as possible, and then published a paper about it in the Journal of Food Science. … ‘Quantification of Pizza Baking Properties of Different Cheeses, and Their Correlation with Cheese Functionality.’”

“For cheese to brown, the paper explains, it needs to lose moisture first. For the moisture to evaporate, blisters need to form, because where they lift the surface of the cheese, free oil can run off and expose the surface to raw heat. And for a blister to form, steam needs to collect in a pocket and push up the cheese.”

“This is why mozzarella makes for good browning. First, it doesn’t have much free oil. Second, it is very elastic. Third, it contains a lot of moisture. So steam pockets form easily, which create healthy blisters, which quickly expose the surface to browning.”

Facebook is Like a Disease, But Recovery is Near

Facebook is Like a Disease, But Recovery is Near

“A new study of Facebook has predicted that the social network’s rapid growth will prove unsustainable and that the site will lose 80 per cent of its users between 2015 and 2017.

A group of Princeton researchers has compared Facebook to a highly infectious disease, claiming that after it reaches a certain critical mass of ‘infected’ users, these individuals will ‘recover’ and quit the site.”

— “Facebook is an ‘infectious disease’ and will lose 80% of users by 2017, according to researchers,” James Vincent, The Independent

Free College for the Rich

“Most people taking free online courses worldwide are among the best-educated and wealthiest of the population, casting doubt on the idea that the classes will benefit the disenfranchised, a survey showed.

More than half of those taking massive open online courses, or MOOCs, were men and the majority were already employed, according to Ezekiel Emanuel, vice provost for Global Initiatives at the University of Pennsylvania and one of the authors of the correspondence piece in today’s journal Nature.”

Breeding Burpless Bovines

Methane and other greenhouse gasses are heating up the world’s atmosphere, fueling global warming. 18% of those gases come from the burps and farts of the billions of cows in the vast herds feeding the world’s growing appetite for meat. Face it, Earth’s human population isn’t going to go Vegan, and cow-mounted catalytic converters just don’t cut it. What’s to be done?

Lab-Testing Tattoos

Lab-Testing Tattoos

“A study by Swami and Furnham (2007) showed that tattooed women were rated as less physically attractive but more sexually promiscuous. Given that men interpret women’s sexual intent according to their physical appearance, we predicted that women with tattoos would be more favorably approached by men. A temporary tattoo was placed on confederates’ lower back, or not, and all confederates were instructed to read a book while lying flat on their stomach on a well-known beach. Two experiments were conducted. The first experiment showed that more men (N = 220) approached the tattooed confederates and that the mean latency of their approach was quicker. A second experiment showed that men (N = 440) estimated to have more chances to have a date and to have sex on the first date with tattooed confederates. However, the level of physical attractiveness attributed to the confederate was not influenced by the tattoo condition. “

Cell Phones & High Blood Pressure

May 18, 2013

Cell Phones & High Blood Pressure

The highlight of the 28th Annual Scientific Meeting of the American Society of Hypertension this week was a study suggesting that mobile phone calls may raise your blood pressure. The study, conducted at Northern Italy’s Guglielmo da Saliceto Hospital, found that subjects talking on their telefonini had a significant rise in blood pressure, from 121/77 to 129/82. Frankly, we wonder if BP rose because subjects were irritated when their phone calls were interrupted by blood pressure tests.

3-D Movies

“Seeing 3D movies can increase rating of symptoms of nausea, oculomotor and disorientation, especially in women with susceptible visual-vestibular system. Confirmatory studies which include examination of clinical signs on viewers are needed to pursue a conclusive evidence on the 3D vision effects on spectators.”

Beach Research

An astounding new wave of beach research is breaking in science circles. The latest findings will sweep you away: people prefer to bask on beaches on sunny days.

Mind-boggling. This follows an earlier study proving that it’s harder to swim with your clothes on.
