Nutrionists writing in Ageing Research Reviews have coined a new syndrome called "osteosarcopenic obesity" - they say they have linked the deterioration of bone density and muscle mass with obesity. it explains how many obese individuals experience a triad of problems that place them at a higher risk for falling and breaking bones, they note. 

Nutrition professor Jasminka Ilich-Ernst of Florida State University began looking at the connections between bone, muscle and fat mass a few years ago, believing that most scientists were examining bone issues without taking into consideration muscle mass and strength, let alone fat tissue.

Geologists have analyzed 40 meteorites that fell to Earth from Mars those chemical signatures have revealed some secrets of the early Martian atmosphere.

The atmospheres of Mars and Earth diverged in important ways very early in the 4.6 billion year history of our solar system.

Of course, what everyone wants to know is if life ever existed there and how water flowed in the past. Those answers are still waiting to be found but researchers are learning where to look.

On the scale of earth-friendly materials, most people don't think of polyester but scientists are figuring out how to extract a natural, waterproof, antibacterial version of it from...cork.
Writing in Biomacromolecules, Cristina Silva Pereira and colleagues explain that polyesters are ubiquitous in modern life, and for good reason. Their durability and other traits make them ideal for use in cushioning and insulating materials, in liquid crystal displays, holograms, filters, and as a high-gloss finish on guitars and pianos.

If you were a blonde girl or boy captured in a raid a few hundred years ago, you were an exotic luxury item so valuable it was worthwhile to transport you to far-away markets in Asia.

Slave-trading was so common the routes stretched from Finland, the Russian Karelia and the Baltic Countries all the way to the Caspian Sea and central Asia.

Finland to Asia? Rarely, of course. Only the largest merchants, with a buyer already in place, would hire gangs from the Volga to capture people and then hazard that journey. Writing

There's a disturbing, though funny to outsiders, trend sweeping green conscious corporations on the coasts of the United States - flurries of emails between indignant employees talking about how long their cars have been plugged in.

Though subsidies and public relations campaigns for electric cars are everywhere to be found, improvements in batteries have been absent for decades. Unless we want acid rain to come roaring back, there needs to be an improvement. Electric car companies are not going to spearhead the research, they are enjoying their 1950s-style "planned obsolescence" and have no reason to cause people to buy cars less often.

Earth Day is fast approaching and, let's face it, if you celebrate Earth Day you probably hate science. And you really hate chemists. 

But there has never been a reason for it, it is simply modern chemophobia. If you ask an environmentalist if they should use a chemical solvent or baking soda to clean, they will say baking soda - but baking soda is a toxic synthetic chemical (NaHCO₃) unless it is used properly, where it is harmless and biodegradable. 

A larger waist circumference is associated with higher risk of postmenopausal breast cancer, according to a paper by American Cancer Society researchers in Cancer Causes, and Control which disputes previous findings that body shape itself is an independent risk factor for breast cancer. 

A significant body of research has linked abdominal obesity to a number of conditions, including heart disease, type II diabetes, and breast and other cancers. Those studies have led to the belief that having an "apple shaped" body, with weight concentrated in the chest and torso, is riskier than having a "pear-shaped" body, with fat concentrated in the hips, thighs and buttocks. 

A quasiparticle called the exciton is responsible for the transfer of energy within devices, such as solar cells, LEDs, and semiconductor circuits, and has been understood for decades, but exciton movement within materials has never been directly observed.

Last winter's curvy jet stream pattern brought mild temperatures to western North America and harsh cold to the East and it may have seemed exceptional in the era of 24-hour news, but it's been happening that way for about 4,000 years, according to a new study. 

Since the discovery of the Antarctic ozone hole, scientists, policymakers, and the public have wondered whether we might someday see a similarly extreme depletion of ozone over the Arctic.

A new MIT study finds it isn't a big worry. In the 30 years of international efforts to limit ozone-depleting chemicals, ozone levels in the Arctic haven't yet sunk to Antarctica levels. Picking one solution and declaring it the savior may not be valid; in Canada, ozone-depleting chemicals dropped but ozone still went up, forcing policymakers to scramble and claim it must be coming from Asia.
