Researchers at MIT and Arizona State University have designed a computer program that allows users to translate any free-form drawing into a two-dimensional, nanoscale structure made of DNA.

Until now, designing such structures has required technical expertise that puts the process out of reach of most people. Using the new program, anyone can create a DNA nanostructure of any shape, for applications in cell biology, photonics, and quantum sensing and computing, among many others.

"What we're looking at is evolution at a structural level. A receptor with a toadstool structure that stems from way back and the common ancestors of insects and humans..."

A receptor that is a 'recipient' for the absorption of vitamin B12 is what he is talking about here - Associate Professor, PhD Christian Brix Folsted Andersen from the Department of Biomedicine at Aarhus University in Denmark. Vitamin B12 is the vitamin that we - even with a healthy diet - most often lack which in turn can lead to serious anaemic diseases and symptoms from the central nervous system.

If teen partner rape could be predicted, it could be better prevented. Social scientists from Michigan State University are helping close that gap by identifying risk factors linked to sexual violence in young women's first relationships in life.

Writing in the January 3 issue of Cancer Cell, researchers at University of California San Diego School of Medicine report that detection of "copy editing" by a stem cell enzyme called ADAR1, which is active in more than 20 tumor types, may provide a kind of molecular radar for early detection of malignancies and represent a new therapeutic target for preventing cancer cell resistance to chemotherapy and radiation.

RENO, Nev. - Winter snows are accumulating in the Sierra Nevada Mountains, creating the snowpacks that serve as a primary source of water for the western U.S.

University of Arizona biomedical engineering professor Philipp Gutruf is first author on the paper Fully implantable, optoelectronic systems for battery-free, multimodal operation in neuroscience research, published in Nature Electronics.

CORVALLIS, Ore. - A higher intake of vitamin C is crucial for metabolic syndrome patients trying to halt a potentially deadly cycle of antioxidant disruption and health-related problems, an Oregon State University researcher says.

That's important news for the estimated 35 percent of the U.S. adult population that suffers from the syndrome.

Boston, MA - Medicare's randomized trial of a new bundled payment model for hip and knee replacement surgeries led to $812 in savings per procedure, or a 3.1% reduction in costs, when compared with traditional means of paying for care, according to new research from Harvard T.H. Chan School of Public Health and Harvard Medical School. The study found that the bundled payment model was also associated with a reduction in use of skilled nursing care after the hospitalization, but had no effects on complication rates among patients.

There is no compelling evidence to indicate important health benefits of non-sugar sweeteners, and potential harms cannot be ruled out, suggests a review of published studies in The BMJ today.

Growing concerns about health and quality of life have encouraged many people to adopt healthier lifestyles and avoid foods rich in sugars, salt, or fat. Foods and drinks containing non-sugar sweeteners rather than regular ("free") sugars have therefore become increasingly popular.

Research suggests a specific treatment for Homozygous Familial Hypercholesterolaemic (HoFH) pateints; a combination therapy with PCSK9-inhibitors (PCSK9-I) and lipoprotein-apheresis (LA) may have synergistic effects on circulating lipid and lipoprotein levels. The relationship with the treatment regimen mentioned above can be investigated further with larger datasets.

Researchers have identified a group of genes that induces differences in the developing brains of male and female roundworms and triggers the initiation of puberty, a genetic pathway that may have the same function in controlling the timing of sexual maturation in humans.

The study, led by Columbia University scientists, offers new evidence for direct genetic effects in sex-based differences in neural development and provides a foundation to attempt to understand how men's and women's brains are wired and how they work.

CAMBRIDGE, MA -- Researchers from MIT and elsewhere have recorded, for the first time, the "temporal coherence" of a graphene qubit -- meaning how long it can maintain a special state that allows it to represent two logical states simultaneously. The demonstration, which used a new kind of graphene-based qubit, represents a critical step forward for practical quantum computing, the researchers say.

A ground-breaking new study led by researchers from the Lady Davis Institute (LDI) at the Jewish General Hospital (JGH) has succeeded in compiling an atlas of genetic factors associated with estimated bone mineral density (BMD), one of the most clinically relevant factors in diagnosing osteoporosis. The paper, published in Nature Genetics, identifies 518 genome-wide loci, of which 301 are newly discovered, that explain 20% of the genetic variance associated with osteoporosis.

CHAMPAIGN, Ill. -- By enticing away the repressors dampening unexpressed, silent genes in Streptomyces bacteria, researchers at the University of Illinois have unlocked several large gene clusters for new natural products, according to a study published in the journal Nature Chemical Biology.

According to the National Cancer Institute, patients diagnosed with non-small cell lung cancer (NSCLC) between the years 1995 and 2001 had 15 percent chance of being alive 5 years later. For patients with stage IV disease, describing cancer that has spread to distant sites beyond the original tumor, that statistic drops to 2 percent. Now a University of Colorado Cancer Center study published in the Journal of Thoracic Oncology tells a much more optimistic story.
