Wolves likely were likely domesticated by European hunter–gatherers over 18,000 years ago and gradually evolved into dogs, according to a genetic analysis. There is debate over when dogs were domesticated and whether it was linked with the development of agriculture or it occurred much earlier. The new work claims that dogs were domesticated between 18,000 and 32,000 years ago.

Jupiter's Great Red Spot, a massive storm big enough to engulf the Earth two times over, is one of the solar system's most enigmatic landmarks and a mystery of fluid dynamics  – because it  should have disappeared centuries ago. 

Some new work will be presented by Pedram Hassanzadeh, a postdoctoral fellow at Harvard and Philip Marcus, a professor of fluid dynamics at Berkeley at the annual meeting of the American Physical Society's Division of Fluid Dynamics in Pittsburgh on November 25th. They think they can explain why Jupiter's Great Red Spot persists

"Based on current theories, the Great Red Spot should have disappeared after several decades. Instead, it has been there for hundreds of years," said Hassanzadeh. 

You can use a laser to demonstrate the Tyndall effect. A simple cat toy (laser pointer) will do but for this demonstration I’ll be using the laser from my DIY Laser Interferometer. “The Tyndall effect, also known as Tyndall scattering,” according to Wikipedia, “is light scattering by particles in a colloid or particles in a fine suspension.” You can use the laser to test three different mixtures: solutions, colloids, and suspensions.

Parts needed:

250 ml beaker

Teaspoon

Eyedropper

Table salt (NaCl)

Milk

Dirt from your garden

Tap water

When the Supreme Court was debating the legal foundation of the Affordable Care Act in the United States, Justice Antonin Scalia challenged the Obama administration claim that the controversial individual mandate provision was Constitutionally legitimate, even under the broad 'Commerce' clause.

"Could you define the market -- everybody has to buy food sooner or later, so you define the market as food, therefore, everybody is in the market; therefore, you can make people buy broccoli," Scalia said. 

It  happens in 1995, toward the end of Run 1B of the Fermilab Tevatron, in the middle of a otherwise anonymous store. The CDF detector is taking good data, and the shift crew in the control room take care of the usual business - a look at the colourful monitors that plaster the walls, a check at trigger rates, the logging of a few standard warnings issued by the data acquisition system, and the occasional browsing of e-mails.

Beginning two decades ago, attention deficit hyperactivity disorder (ADHD) diagnoses jumped to 11 percent of American children aged 4 to 17 even though neuroscientists still did not know biologically what ADHD is. 

Talking about "the 1 percent" has become a popular pastime, though usually the person doing the talking means someone else - outside TV commercials no one ever cops to being The Man.(1) Protesters in the Occupy Wall Street movement meant it about rich, which investment bankers, for example, so they dutifully ignored the opulent wealth of Kanye West and his $355 t-shirt, Balmain jeans, Givenchy plaid and gold chains when he visited to show support for their cause.

While he buys t-shirts to wear for $355 he only sells his own brand to young fans for $120 each. See? He is such a giver and therefore not part of the 1 percent.

A new integrative medicine paper examines the role of gut bacteria on the maturation of the immune system and claims evidence supporting the use of butyrate as therapy for inflammatory bowel diseases like Crohn's disease, based on mouse models.

Butyrate, a by-product of the digestion of dietary fiber by gut microbes, is believed to act as an epigenetic switch that boosts the immune system by inducing the production of regulatory T cells in the gut. 

A new paper in the Journal of Food Science says the buffaloberry could be the next super food du jour because it contains large amounts of lycopene and a related acidic compound, methyl-lycopenoate, which are important antioxidants and nutrients beneficial for human health.

The bright red fruit has a tart flavor, and was historically used as a source of nutrients for Native Americans. The sugar and acidity of the fruit make it desirable as a fresh or dried product.

In addition to its potential health benefits, lycopenoate may also be used as a natural food colorant. Recently the buffaloberry has drawn attention from several commercial wine producers.

A comprehensive analysis of more than 1 million hospital admissions has found that over 50 percent of non-surgical patients were prescribed 
opioid pain medications
 during their hospitalizations, often at very high doses, and that more than half of those exposed were still receiving these medications on the day they were discharged from the hospital.

Opioids are narcotic pain medications including morphine, oxycodone and fentanyl. In recent years, the problem of opioid addiction and overdoses has grown more acute, with updated figures from the Centers for Disease Control and Prevention (CDC) reporting that the rate of fatal overdoses from opioids nearly quadrupled over the last decade, with estimates of more than 14,000 deaths from opioid overdoses annually.
