|  Carbon capture and storage: An inside look at a metal-organic framework (MOF) in action  | 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. | Read More » Biodiversity higher in the tropics, but species more likely to arise at higher latitudes  | 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. | Read More » Copper promises cheaper, sturdier fuel cells  | 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. | Read More » Expert assessment: Sea-level rise could exceed one meter in this century  | 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. | Read More » Decoding, oral comprehension, vocabulary: Three key literacy skills for primary schools in priority areas  | 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. | Read More » Smaller islands host shorter food chains  | 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. | Read More » Artificial skin created using stem cells from the umbilical cord  | 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. | Read More » Connections in children's brains strengthen during sleep  | While young children sleep, connections between the left and the right hemispheres of their brain strengthen, which may help brain functions mature, according to a new study. | Read More » Intestinal bacteria influence food transit through the gut  | 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. | Read More » Frequent breaks from sedentary behavior makes kids healthier  | 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. | Read More » Recessions in mid-life linked to higher risk of cognitive decline  | 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. | Read More » PTSD raises risk for obesity in women  | 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. | Read More » Current practice may over-diagnose vitamin D deficiency  | The current "gold standard" test for measuring vitamin D status may not accurately diagnose vitamin D deficiency in black individuals. A team of researchers has found that genetic differences in a vitamin D carrier protein may explain the discrepancy between the prevalence of diagnosed vitamin D deficiency in black Americans and a lack of the usual symptoms of vitamin deficiency. | Read More » Too much weekly sport seems to be as bad as too little for teen wellbeing  | 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. | Read More » Long-term unemployment may accelerate aging in men  | Men who are unemployed for more than two years show signs of faster aging in their DNA, a new study has found. | Read More » Political correctness could affect holiday weight gain  | 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. | Read More » Powerful tool for genetic engineering  | 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. | Read More » Link between allergies, increased risk of blood cancers in women  | A team of scientists looking into the interplay of the immune system and cancer have found a link between a history of airborne allergies – in particular to plants, grass and trees – with risk of blood cancers in women. | Read More » Stuck on flu  | Researchers have shown for the first time how influenza A viruses snip through a protective mucus net to both infect respiratory cells and later cut their way out to infect other cells. | Read More » Human expansion is leaving osprey of Canaries cornered  | A team of scientists in the Canary Islands has concluded in a study that human expansion could be one of the main causes of the precarious situation of ospreys in the archipelago, a species at risk of extinction. The osprey, an endangered bird species, has sparse spawning stock in the Canaries. | Read More » Sugar-sweetened beverage consumption increases endometrial cancer risk  | Postmenopausal women who consumed sugar-sweetened beverages were more likely to develop the most common type of endometrial cancer compared with women who did not drink sugar-sweetened beverages, according to a study published. | Read More » | |
