We know that ancient Japanese gold leaf artists were truly masters of their craft - their works are ornate and delicate.

What remains a mystery is how artifacts were gilded with gold leaf that was hand-beaten to the nanometer scale. Gold leaf refers to a very thin sheet made from a combination of gold and other metals. It has almost no weight and can only be handled by specially designed tools. Even though the ancient Egyptians were probably the first to gild artwork with it, the Japanese have long been credited as being able to produce the thinnest gold leaf in the world.

A systematic review and meta-analysis of available data published in Diabetologia suggests that combined aerobic and resistance training, rather than either alone, is best for controlling both blood sugar and blood fat profiles among people with type 2 diabetes.

However, the authors stress that the strength of the results is weakened when studies with high risk of bias are removed, and thus more high quality trials are needed to make more definitive conclusions. 

The UK government is in a deficit crisis. Unlike the US, they seem to worry about it.

In order to reduce the deficit, they have taken steps to make welfare less of a chronic lifestyle. 

Since 2010 the UK government has introduced a raft of reforms to the welfare system in a bid to reduce the deficit, but a total of 1,056 GPs across the UK who completed a survey (out of 28,602 who were contacted) lead the authors of a recent paper in BMJ to suggest that people receiving welfare support due to illness or disability are struggling to cope with cuts to their benefits and are turning to their GP practices for help - which has increased the workload for doctors.

The argument for making marijuana legal despite its health risks is that so many people use it anyway that it creates a society of casual criminals at best - maybe they are getting a bogus prescription for 'pain' or glaucoma or inventing some way it helps them. And at worst it makes criminals rich and puts users at risk because the quality is unmonitored and perhaps even dangerous.

Scorpions build a platform on which to warm up before the evening hunt. 

As older adults typically have one or more chronic health conditions that can affect dietary intake, malnutrition has been identified as a serious problem in older adults. This has given rise to the recommendation that nutrition screenings be a mandatory part of the comprehensive geriatric analysis (CGA).

The CGA, first developed in the 1930s, is a multidimensional diagnostic process that looks at a frail elderly person's medical, psychosocial, and functional capabilities in order to develop an overall plan for treatment and follow-up. While it has been used across health settings, the CGA is typically used in a geriatric specialty unit by a team that includes physicians, nurses, dietitians, pharmacists, therapists, and social workers.

IBM takes data seriously, as seriously as they took Business Machines back in their early days.

They want to be the resource for the blanket concept of The Internet Of Things. Someone will have to do it, because the amount of information available today is overwhelming. When you can produce 250 gigabytes of data an hour, you have too much data.

Or you are onto something big.

Why do females sometimes ignore males and sometimes stop and pay attention?

There are many conjectures: looking like Ryan Gosling seems to help but there are a lot of other variables: if the female is under the age of 30, a male being unemployed while he 'gets his band together' is sometimes fine, yet after age 30 females regard that as unacceptable.

People have been debating whether experts are "born" or "made" since the mid-1800s. In recent years, deliberate practice has received considerable attention in these debates, while innate ability has been pushed to the side, due in part to the famous "10,000-hour rule" popularized by Malcolm Gladwell in his 2008 book Outliers. 

During discussions of the Affordable Care Act, there was concern that some procedures would be harder to obtain. There was even worry about 'death panels' such as in the United Kingdom National Health Service.

It will be just the opposite in the short term, based on how utilization changed after earlier insurance reform in Massachusetts, according to an article by Chandy Ellimoottil, M.D., of the University of Michigan, Ann Arbor, and colleagues.

By looking at insurance expansion and utilization of discretionary and non-discretionary surgical procedures in one state, they project that surgery will go up - at least until taxpayers start getting the bill.
