You know why soup tastes good - and your dogs love it too. It's bone marrow fat. Now it may be healthier to eat delicious.

A study has found that the fat tissue in bone marrow is a significant source of the hormone adiponectin, which helps maintain insulin sensitivity, break down fat, and has been linked to decreased risk of cardiovascular disease, diabetes, and obesity-associated cancers. 

Want to send a message to possible invaders? Pile dead bodies high and deep. A new species of wasp does just that.

This wasp with a unique nest-building strategy was discovered in the forests of southeast China. The "bone-house wasp" shuts off its nest with a chamber full of dead ants in order to protect its offspring from enemies, as shown by Michael Staab and Prof. Dr. Alexandra-Maria Klein from the Institute of Earth and Environmental Sciences of the University of Freiburg as well as scientists from the Museum für Naturkunde Berlin and the Chinese Academy of Sciences in Beijing.

No other such strategy has ever been discovered before in the animal kingdom. 

Iron is one of the essential elements of life. Found in enzymes like myoglobin and hemoglobin and cytochrome P450, iron is an essential cog in the biomachinery of every living cell. 

Iron is present in tiny concentrations in seawater. On the order of a few billionths of a gram in a liter.  Given that there is so little iron in seawater, one might conclude that its presence there is inconsequential, but its scarcity in the ocean, the earth's wellspring of life, only magnifies its importance. 

Dyslexic adults in a representative sample of 13,054 adults aged 18 and over in the 2005 Canadian Community Health Survey included 1,020 respondents who reported that they had been physically abused during their childhood and 77 who reported that they had been diagnosed by a health professional with dyslexia. 

That translates to 35 percent of Canadian adults with dyslexia reporting they were physically abused before they turned 18. In contrast, 7 percent of those without dyslexia reported that they had experienced childhood physical abuse. 

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 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.

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.

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.

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.
