Countries with a higher per capita gross domestic product (GDP) are more likely to have searches for information about the future than information about the past, according to an analysis of Google search queries in Scientific Reports.Is there a link between online behavior and real-world economic indicators?  Maybe.

Sand is so fundamental it seems simple - like a magnetic field, just because an industry is built around something doesn't mean we understand it - but granular material like sand is actually tricky to model. From a distance, flowing sand resembles a liquid, streaming down the center of an hourglass like water from a faucet, but up close individual grains slide against each other, forming a mound at the base that holds its shape, much like a solid. 

It's baseball season.  That means some time this week you are sure to witness the following; a pitcher hits a player with the ball.  The opposing pitcher retaliates by hitting another player with a ball.  The benches look like they are about to clear, an umpire will issue a warning (or not) and things will escalate until, surely, a fight breaks out.The Iron Dice of World War I and the many mysteries of how it actually came to fighting has nothing on the psychological machinations of America's national pastime.

Every few years, an international test is given and American students finish in the middle of the pack.  They went up during the 2000s but American kids have never been at the top - international students learn facts and American kids learn 'how to think'. Americans were 11th out of 12 countries taking the international assessment the first time it was given in the early 1960s.  They are not testing what American students are learning.Given the rampant criticism educators, the government and students get from cultural pundits ('dismal', 'being left behind', etc.) each time one of those assessments is given, it seems like a non-starter to try and change education to teach more critical thinking.

Self-esteem programs have worked.  Of 3,500 college applicants, more than a third couldn't report their weight accurately. The heavier they were, the less accurate their estimates. Overweight and obese men were even more likely to underestimate their weight than overweight and obese women.The results were part of the Up Amigos project, a collaboration between collaborators at the University of Illinois and the Universidad Autónoma de San Luis Potos in Mexico. In physical exams, the height, weight, and body mass index (BMI) of 3,622 18- to 20-year-old applicants to the Mexican university were recorded; the aspiring students also completed surveys in which they reported their weight status.

A protein found on the surface of immune cells called dendritic cells recognizes dangerous damage and trauma that could signify infection. Dendritic cells are critical for raising the alarm about the presence of foreign invaders in the body such as viruses, bacteria and parasites as well as tumor cells and other dead or damaged cells. Also known as antigen-presenting cells, they digest and present molecules from damaged cells to other immune cells that recognize foreign invaders and launch an immune response.

A new study says it has ended the long-lasting debate on the causes of dyslexia and also opened the way to a new approach for early identification and interventions for the 10 percent of children for whom reading is extremely difficult. For children with dyslexia, the trouble begins even before they start reading and for reasons that don't necessarily reflect other language skills. Researchers say their new report reveals a causal connection between early problems with visual attention and a later diagnosis of dyslexia.

Early cancer diagnosis is vital for treating breast cancer - and one in eight women will be diagnosed with breast cancer, according to an article in Molecular&Cellular Proteomics - but early detection is still challenging as testing by mammography remains cumbersome, costly, and in many cases, cancer can only be detected at an advanced stage.A team based in the Dept. of Biomedical Engineering at McGill University's Faculty of Medicine has developed a new microfluidics-based microarray that could change how and when cancer is diagnosed.

The Multi-Mode Sensor Seeker (MMSS), a sensor which is a mix of high-definition cameras, mid-wave infrared sensors and laser-radar (LADAR) technology, will start airborne tests this summer. It will be placed on a robotic helicopter called Fire Scout and carry advanced automatic target recognition software, so sensor prototype will allow Fire Scout to autonomously identify small boats on the water, reducing the workload of sailors operating it from control stations aboard Navy ships.Look out pirates. You're now that much easier to find. 

Despite claims that there is not enough diversity in anonymous, voluntary efforts, it often comes down to choice.  Women are not discriminated against on Wikipedia, though more men do it, and white people are not prevented from blogging just because more black people do it.  Black people, nee African-Americans in American sociology papers, are more likely to blog than their white and Hispanic counterparts, according to surveys analyzed by a researcher at the University of California, Berkeley - one and a half times to nearly twice as much as whites.

Illicit drug use is more common in older people than ever before - but that's because they did it the most when they were younger and they are more likely than ever to survive into old age.New research published in Age and Ageing found that the lifetime use of cannabis, amphetamine, cocaine and LSD in 50-64 year olds has significantly increased since 1993 and is much higher than lifetime use in adults aged over 65. The study also found that drug use in inner London was higher than the overall UK average.The study analyzed data on illicit drug use from two household surveys*. The most recent national survey included 2,009 people aged 65 and 1,827 people aged 55-65. The inner London survey included 284 and 176 people in these respective age groups

Palaeontologists have found that not all Easter eggs come from the same “parent” species -  some could be from dinosaurs, including a new species from the Pyrenees. An international group of researchers has helped to determine that dinosaurs have shaped the Easter eggs we buy.Scientists were investigating whether 70 million-year-old fossil eggs found in the Pyrenees were laid by birds, or their dinosaur ancestors - researchers from the University of Leicester extended the study further by comparing Easter egg shapes to those of birds’ and dino eggs.
