We age because the cells in our bodies begin to malfunction over the years. This is the general view that scientists hold of the ageing process. For example, in older people the cells' internal quality control breaks down. This control function usually eliminates proteins that have become unstable and lost their normal three-dimensional structure. These deformed proteins accumulate in the cells in a number of diseases, such as Parkinson's and Alzheimer's.

Plastic solar cells are light, easy to install, and readily produced using a printer. Nevertheless, the processes that take place on the molecular scale during the production of organic solar cells are not yet entirely clear. Researchers from the Technical University of Munich (TUM) have now managed to observe these processes in real time. Their findings, which are published in the specialist journal Advanced Energy Materials, could help to improve the efficiency of organic solar cells.

Leading on from The Genome Analysis Centre's (TGAC) previous announcement of their new bread wheat genome assembly, the landmark resource is now publically available to download at the European Bioinformatics Institute's (EMBL-EBI) Ensembl database for full analysis.

Trophy hunting shouldn't be banned but instead it should be better regulated to ensure funds generated from permits are invested back into local conservation efforts, according to a new paper co-authored by a leading University of Adelaide conservation ecologist.

LOS ANGELES (Jan. 7, 2016) -- A new technique that has the potential to treat inherited diseases by removing genetic defects has been shown for the first time to hinder retinal degeneration in rats with a type of inherited blindness, according to a Cedars-Sinai study.

An international research team at Tohoku University's Advanced Institute of Materials Research (AIMR) succeeded in chemically interconnecting chiral-edge graphene nanoribbons (GNRs) with zigzag-edge features by molecular assembly, and demonstrated electronic connection between GNRs. The GNRs were interconnected exclusively end to end, forming elbow structures, identified as interconnection points (Fig. 1a).

With increasing age, the propensity to take physical, social, legal or financial risks decreases. Researchers from the University of Basel and the Max Planck Institute for Human Development in Berlin were able to show how factors such as poverty and income equality play a role. Their study based on data from 77 countries has been published in the journal Psychological Science.

Wilson disease is a genetic disorder in which copper accumulates to toxic levels in tissues, leading to neurological symptoms and liver disease. Diagnosis of the disease is challenging because symptoms can vary widely across patients. The mechanisms underlying this clinical heterogeneity are unclear. Using a genome-wide approach in a new dog model for copper toxicosis, a team of researchers led by Hille Fieten have now revealed that mutations in a copper transporter gene, ATP7A, can ameliorate symptoms of the disease.

A study by researchers at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) has identified a new mechanism through which hematopoietic stem cells (HSCs) control both their own proliferation and the characteristics of the niche that houses them. This control is exercised by the protein E-Selectin Ligand-1 (ESL-1). The research team, led by Drs. Andrés Hidalgo and Magdalena Leiva, detected high expression of ESL-1 in HSCs and also found that it controls their production of the cytokine protein TGF-?. This is important because TGF-?

When the Ebola virus outbreak erupted in West Africa in 2014, children infected with the virus -- particularly those under age 5 -- faced overwhelming challenges. Not only was there a high death rate among young children infected with the disease, they often were isolated from their families, leaving them feeling distressed and without the intensive care they needed.

The Romans are well known for introducing sanitation technology to Europe around 2,000 years ago, including public multi-seat latrines with washing facilities, sewerage systems, piped drinking water from aqueducts, and heated public baths for washing. Romans also developed laws designed to keep their towns free of excrement and rubbish.

New findings from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), confirm dihydroartemisinin-piperaquine, the first-line treatment for Plasmodium falciparum malaria infection in Cambodia, has failed in certain provinces due to parasite resistance to artemisinin and piperaquine. Dihydroartemisinin-piperaquine is an artemisinin combination therapy (ACT) for malaria that combines potent, fast-acting artemisinin with a long-acting partner drug, piperaquine.

A study by Simon Fraser University researchers suggests that the number of children born to a woman influences the rate at which her body ages.

The study led by health sciences professor Pablo Nepomnaschy and postdoctoral researcher Cindy Barha found that women who give birth to more surviving children exhibited longer telomeres. Telomeres are the protective tips found at the end of each DNA strand and are indicative of cellular aging. Longer telomeres are integral to cell replication and are associated with longevity.

ANN ARBOR, Mich. - For a long time researchers have tracked high rates of obesity among black and Hispanic kids, but a closer look at communities shows family income matters more than race in predicting which kids are overweight.

Using a model created from data on 111,799 Massachusetts students, the University of Michigan Health System showed that as poverty rises, so does the rate of obesity among children in 68 of its public school districts.
