We've gotten used to taking pills for everything that ails us, but medications have side effects and cost money. It takes some discipline, but in many cases, the nonpharmacological approach can do as much as pills. Seven common conditions are listed along with treatment options that don't require taking medication.
Scientists have made an important step on the long road to artificially mimicking photosynthesis. They were able to synthesise a stable inorganic metal oxide cluster, which enables the fast and effective oxidation of water to oxygen. Artificial photosynthesis may decisively contribute to solving energy and climate problems, if researchers find a way to efficiently produce hydrogen with the aid of solar energy.
Researchers have shown that Magnetic Resonance Imaging technology has the potential to non-invasively characterize tumors and determine which of them may be responsive to specific forms of treatment.
One day soon patients may spit in a cup, instead of bracing for a needle prick, when being tested for cancer, heart disease or diabetes. A major step in that direction is the cataloguing of the "complete" salivary proteome, a set of proteins in human ductal saliva, identified by a consortium of three research teams, according to a new article.
While communication may be recognized as a universal phenomenon, differences between languages -- ranging from word order to semantics -- undoubtedly remain as they help to define culture and develop language. Yet, little is understood about similarities and differences in languages around the world and how they affect communication. Recently, however, two studies have emerged that aid in our understanding of cross-linguistic distinctions in language usage.
Scientists have for the first time isolated from the environment and fully characterized the organism that causes Buruli ulcer. The study lends support to the idea that the organism, Mycobacterium ulcerans, is transmitted to humans from environmental aquatic niches, rather than from person-to-person.

Neuroscientists have developed a technique for extracting useful quantities of insect blood from a single fruit fly. The technique may prove useful in genetic studies and for studying minute amounts of fluid from disease hot-spots, such as those where some retinal diseases begin.
A new study predicts that climate change will irreversibly alter water circulation in Lake Tahoe in the Western US, radically changing the conditions for plants and fish in the lake -- and it could happen in 10 years.
Colon cancer screening is a tough sell. It's icky, uncomfortable and the thought of a colonoscopy, especially the prep, can be intimidating, to say the least. But here's what clinches the sale: Colon cancer can be largely prevented through proper screening.
It is well established that Id1, a gene normally produced only in embryonic development, is reactivated in many "solid" cancers, or carcinomas. New research shows that by 'switching off' the Id1 gene, it is possible to induce a state of 'senescence', or permanent sleep, within a tumour, preventing it from growing or spreading.
