Health authorities should emphasize the positive message that the most successful method used by most ex-smokers is unassisted cessation, despite the promotion of cessation drugs by pharmaceutical... Continue reading ...

Researchers in fluid dynamics have studied algae to illuminate fluid mechanics. One of the researchers said, "Nature has long inspired researchers in fluid mechanics to explore the mechanical... Continue reading ...

Colorectal adenocarcinoma accounts for the majority of cases of colorectal cancer. A series of genetic mutations in the cells lining the colon (intestinal epithelial cells) is thought to be the cause... Continue reading ...

Scientists in Spain report on the formation of the small-diameter respiratory tubes of the fly Drosophila -- a process that resembles the development of the finest blood vessels, the capillaries, in... Continue reading ...

New research has identified a new type of cellular senescence (i.e., irreversible arrest of cell growth) and determined a way to enhance it to suppress prostate tumor development and growth in mice.... Continue reading ...

Consuming two or more soft drinks per week increased the risk of developing pancreatic cancer by nearly twofold compared to individuals who did not consume soft drinks, according to a new study. Continue reading ...

Climate change will make the world more fragrant, as warming temperatures make plants release more chemicals, according to a major scientific review. Continue reading ...

Cellular imaging offers a wealth of data about how cells respond to stimuli, but harnessing this technique to study biological systems is a daunting challenge. Researchers have now developed a novel... Continue reading ...

Chemokines are a large group of proteins whose predominant function is to direct cell migration. They regulate many physiological and pathophysiological processes, in particular in the immune system.... Continue reading ...

In a unique project to combat depleted fish supplies in Lake Victoria, researchers have established 'boutique' fish farms in small villages around the Lake's shore in Uganda. Continue reading ...

The traditional view is that ecology shapes evolution. Some research has suggested, however, that evolutionary processes reciprocate by influencing ecology in turn. Now biologists present evidence... Continue reading ...

Mice with a genetic change that causes progressive hearing loss in children, also have hearing loss because sound waves are not processed properly. The ear's attempts to compensate for hearing loss... Continue reading ...

A parent's existing health habits or behaviors, like cigarette smoking, may influence the likelihood that they will have their daughters vaccinated against HPV. Continue reading ...

Young people who have experienced threats and violence feel more insecure than others in urban public spaces, especially when alone. Continue reading ...

Rugged, hilly landscapes with a range of different habitat types can help maintain more stable butterfly populations and thus aid their conservation, according to new findings. This has implications... Continue reading ...

Cardiologists and heart imaging specialists at 15 medical centers in eight countries have enrolled the first dozen patients in a year-long investigation to learn whether the subtle squeezing of blood... Continue reading ...

Scientists have identified a double agent in the eye that, once triggered, can morph from neuron protector to neuron killer. The discovery has significant health implications since the neurons killed... Continue reading ...

One of the founding principles of Darwin's theory is that biological evolution has been shaped by the survival of the fittest. Things, however, are not always that simple as researchers have... Continue reading ...

Researchers have used haplotype tagging (hap-tag) single-nucleotide polymorphisms to study the relationship between genetic predispositions, an environmental factor -- bacterial vaginosis -- and... Continue reading ...

A quantum physics trick is set to give smartphones and hand-held devices pressure-sensitive switches and touchscreens. Continue reading ...

Scientists are tapping into the DNA of a wild oat, considered by some to be a noxious weed, to see if it can help combat crown rust, the most damaging fungal disease of oats worldwide. Continue reading ...
