The mothers of Britain's 'mixed families' are ensuring their children learn about their heritage and culture, according to a development project funded by the Economic and Social Research Council (ESRC). So, even if the child's father hails from a minority background, it will still be the mother who is responsible for teaching them about the father's culture.

Plants cannot survive without phosphorus. It forms the backbone of many crucial molecules (such as DNA) and is a key player in energy transfer reactions. Low availability of phosphorus is a major environmental stress for plants and can lead to great losses in crop production. But plants can't make their own phosphorus; they get all they need at the root-soil interface, in the form of inorganic phosphate (Pi), so one way to maximise the amount of phosphorus in the plant is to turn up Pi uptake by root cells.
Our decisions to trust people with our money are based more on how they look then how they behave, according to new research from the University of Warwick.
In a paper recently published in the PLoS One journal, researchers from Warwick Business School, the University College London and Dartmouth College, USA, carried out a series of experiments to see if people made decisions to trust others based on their faces.
A new report published today by the European Commission's in-house science service, the Joint Research Centre (JRC), provides key information for policy makers and business managers on how to assess the environmental impacts of products and services. It helps to pave the way towards a resource-efficient Europe and aims to help design more sustainable products, which are indispensable in a world of 7 billion people and limited resources.
WEST LAFAYETTE, Ind. - Tall, waving corn fields that line Midwestern roads may one day be replaced by dwarfed versions that require less water, fertilizer and other inputs, thanks to a fungicide commonly used on golf courses.
Burkhard Schulz, a Purdue University assistant professor of plant biochemical and molecular genetics, had earlier found that knocking out the steroid function in corn plants would create tiny versions that only had female sex characteristics. But brassinazole, the chemical used to inhibit the plant steroid biosynthesis, was prohibitively expensive.
OAK BROOK, Ill. – A large, multicenter study found that the Breast Imaging and Reporting Data Systems (BI-RADS) terminology used by radiologists to classify breast imaging results is useful in predicting malignancy in breast lesions detected with MRI. Results of the study are published online in the journal Radiology.
Researchers at the University of California, San Diego School of Medicine and Moores Cancer Center have identified a new biomarker and therapeutic target for pancreatic cancer, an often-fatal disease for which there is currently no reliable method for early detection or therapeutic intervention. The paper will be published May 15 in Cancer Research.
ANN ARBOR, Mich.—Researchers found that administering a common chemotherapy drug before bone tumors took root actually fertilized the bone marrow, enabling cancer cells, once introduced, to seed and grow more easily.
The findings provide valuable insight as to why some cancers metastasize to bone, and could eventually result in new metastasis-prevention drugs, said Laurie McCauley, professor in the Department of Periodontics and Oral Medicine at the University of Michigan School of Dentistry and principal investigator on the study.
AUGUSTA, Ga. – A DNA-covered submicroscopic bead used to deliver genes or drugs directly into cells to treat disease appears to have therapeutic value just by showing up, researchers report.
Within a few hours of injecting empty-handed DNA nanoparticles, Georgia Health Sciences University researchers were surprised to see increased expression of an enzyme that calms the immune response.
A number of studies have shown that it is possible to lengthen the average life of individuals of many species, including mammals, by acting on specific genes. To date, however, this has meant altering the animals' genes permanently from the embryonic stage – an approach impracticable in humans. Researchers at the Spanish National Cancer Research Centre (CNIO), led by its director María Blasco, have proved that mouse lifespan can be extended by the application in adult life of a single treatment acting directly on the animal's genes.
A CT-scan-based form of virtual colonoscopy that does not require laxative preparation appears to be as effective as standard colonoscopy in identifying the intestinal polyps most likely to become cancerous. In the May 15 issue of Annals of Internal Medicine, a Massachusetts General Hospital (MGH)-based research team reports finding that the new technique, which uses computer-aided systems both to virtually cleanse and to analyze the images acquired, was able to identify more than 90 percent of the common polyps called adenomas that were 10 mm or larger.
INDIANAPOLIS -- Current colorectal cancer screening guidelines for individuals with first-degree relatives with precancerous colon polyps are based on studies that were not properly designed or were too limited to shape those guidelines, according to a new systemic review of research on the topic. The review authors call for new studies to measure the risk and identify the factors that modify it.
If your parents have a history of high blood pressure, you can significantly reduce your risk of developing the disease with moderate exercise and increased cardiovascular fitness, according to new research in the American Heart Association's journal Hypertension.
In a study of more than 6,000 people, those who had a parent with high blood pressure but were highly fit had a 34 percent lower risk of developing high blood pressure themselves, compared to those with a low-fitness level who had the same parental history.
STANFORD, Calif. — What goes bump in the night? In many U.S. households: people. That's according to new Stanford University School of Medicine research, which found that about 3.6 percent of U.S. adults - or upward of 8.4 million - are prone to sleepwalking. The work also showed an association between nocturnal wanderings and certain psychiatric disorders, such as depression and anxiety.
The study, the researchers noted, "underscores the fact that sleepwalking is much more prevalent in adults than previously appreciated."
