Carbon capture and storage: An inside look at a metal-organic framework (MOF) in action Posted: 22 Nov 2013 10:24 AM PST A unique inside look at the electronic structure of a highly touted metal-organic framework (MOF) as it is adsorbing carbon dioxide gas should help in the design of new and improved MOFs for carbon capture and storage.

Biodiversity higher in the tropics, but species more likely to arise at higher latitudes Posted: 22 Nov 2013 10:24 AM PST A study of 2300 species of mammals and 6700 species of birds helps explain why there are more species in the tropics than at higher latitudes. Researchers found that while the tropics harbor more species, the number of subspecies increases in the harsher environments typical of higher latitudes. The results suggest that the latitudinal diversity gradient may be due higher species turnover -- speciation counterbalanced by extinction -- towards the poles than near the equator.

Political correctness could affect holiday weight gain Posted: 22 Nov 2013 08:58 AM PST As the festivities proceed, so do countless tips for keeping off extra weight this season. But, there is one factor most people likely won't consider -- political correctness. Research suggests you could be choosing unhealthy options to serve your guests because you don't want to offend someone else.

Powerful tool for genetic engineering Posted: 22 Nov 2013 08:27 AM PST Viruses cannot only cause illnesses in humans, they also infect bacteria. Those protect themselves with a kind of "immune system" which -- simply put -- consists of specific sequences in the genetic material of the bacteria and a suitable enzyme. Scientists have now shown that the dual-RNA guided enzyme Cas9 which is involved in the process has developed independently in various strains of bacteria.

Pre-industrial rise in greenhouse gases had natural and anthropogenic causes Posted: 22 Nov 2013 07:39 AM PST For years scientists have intensely argued over whether increases of potent methane gas concentrations in the atmosphere -- from about 5,000 years ago to the start of the industrial revolution -- were triggered by natural causes or human activities. A new study suggests the increase in methane likely was caused by both. A new study, published Friday in the journal Science, suggests the increase in methane likely was caused by both.

Copper promises cheaper, sturdier fuel cells Posted: 22 Nov 2013 07:39 AM PST Chemists are exploring the use of copper nanowires in fuel cells to convert solar energy into storable fuel. Copper nanowire catalysts cost less to produce than their indium tin oxide counterparts because they can be "printed" on pieces of glass or plastic in a liquid ink form, using a machine that functions much like a printing press. The nanowires can also be incorporated into transparent, flexible films.

Sea level rise forecasts helped by insights into glacier melting Posted: 22 Nov 2013 07:38 AM PST Predictions of sea level rise could become more accurate, thanks to new insight into how glacier movement is affected by melting ice in summer.

Expert assessment: Sea-level rise could exceed one meter in this century Posted: 22 Nov 2013 07:38 AM PST Sea-level rise in this century is likely to be 70-120 centimeters by 2100 if greenhouse-gas emissions are not mitigated, a broad assessment of the most active scientific publishers on that topic has revealed. The 90 experts participating in the survey anticipate a median sea-level rise of 200-300 centimeters by the year 2300 for a scenario with unmitigated emissions.

Decoding, oral comprehension, vocabulary: Three key literacy skills for primary schools in priority areas Posted: 22 Nov 2013 07:36 AM PST What types of skills do first-year primary school children in education priority areas need most to learn to read? To find out, scientists conducted a study of 394 children at the end of their first year of school. The results show that, of all the factors involved in their reading comprehension skills, three played a predominant role: decoding ability, oral comprehension and vocabulary.

College students more likely to be lawbreakers if spanked as children Posted: 22 Nov 2013 07:36 AM PST No matter where they live in the world, university students who were spanked as children are more likely to engage in criminal behavior, according to new research. Even young adults whose parents were generally loving and helpful as they were growing up showed higher rates of criminal behavior.

Smaller islands host shorter food chains Posted: 22 Nov 2013 05:45 AM PST That smaller islands will typically sustain fewer species than large ones is a widespread pattern in nature. Now a team of researchers shows that smaller area will mean not only fewer species, but also shorter food chains. This implies that plant and animal communities on small islands may work differently from those on large ones.

Archaeologists discover largest, oldest wine cellar in Near East: 3,700 year-old store room held 2,000 liters of strong, sweet wine Posted: 22 Nov 2013 05:45 AM PST Archaeologists have unearthed what may be the oldest -- and largest -- ancient wine cellar in the Near East, containing 40 jars, each of which would have held 50 liters of strong, sweet wine.

Artificial skin created using stem cells from the umbilical cord Posted: 22 Nov 2013 05:44 AM PST An important scientific breakthrough will aid the immediate use of artificially-grown skin for major burn patients, since the skin could be stored in tissue banks and made available when needed.

Colossal new predatory dino terrorized early tyrannosaurs Posted: 22 Nov 2013 05:42 AM PST A new species of carnivorous dinosaur – one of the three largest ever discovered in North America – lived alongside and competed with small-bodied tyrannosaurs 98 million years ago. Siats meekerorum, (pronounced see-atch) was the apex predator of its time.

Intestinal bacteria influence food transit through the gut Posted: 21 Nov 2013 06:13 AM PST Food transit through the small intestine affects the body's absorption of nutrients and, consequently, our health. The discovery that food transit time is regulated by a hormone indicates new ways to increase the intestinal absorption of nutrients, and thus potentially treat malnutrition.

Frequent breaks from sedentary behavior makes kids healthier Posted: 20 Nov 2013 04:24 PM PST This study suggests that frequent interruptions in children's sedentary time -- or the number of times children got up, rather than the duration of the break -- can have a positive impact on reducing global health risks.

PTSD raises risk for obesity in women Posted: 20 Nov 2013 04:23 PM PST Women with post-traumatic stress disorder (PTSD) gain weight more rapidly and are more likely to be overweight or obese than women without the disorder, find researchers. It is the first study to look at the relationship between PTSD and obesity over time.

Too much weekly sport seems to be as bad as too little for teen wellbeing Posted: 20 Nov 2013 04:23 PM PST Too much weekly sport seems to be as bad as too little for teen well-being, suggesting there's an inverted U shaped relationship between the two.

Recessions in mid-life linked to higher risk of cognitive decline Posted: 20 Nov 2013 04:23 PM PST People who live through economic recessions in early to mid-life may be at higher risk of cognitive decline in later life, suggests research published.

Long-term unemployment may accelerate aging in men Posted: 20 Nov 2013 04:23 PM PST Men who are unemployed for more than two years show signs of faster aging in their DNA, a new study has found.
