Catalysis may initiate almost all modern industrial manufacturing processes, but catalytic activity on solid surfaces is poorly understood. This is especially true for the cellulase enzymes used to release fermentable sugars from cellulosic biomass for the production of advanced biofuels. Now, researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) through support from the Energy Biosciences Institute (EBI) have literally shed new light on cellulase catalysis.

Breast cancers that lack estrogen receptors are more difficult to treat than ER+ cancers. Research presented at the AACR Annual Meeting 2013 demonstrates an investigational drug, Paragazole, that makes triple-negative breast cancer cells express estrogen receptors, and that increases the sensitivity of these cells to chemotherapy.

WINSTON-SALEM, N.C. – April 8, 2013 – Women often point to stress, hormones, alcohol, or even the weather as possible triggers for their migraines. But a new study from Wake Forest Baptist Medical Center found that it is nearly impossible for patients to determine the true cause of their migraine episodes without undergoing formal experiments.

One of the most widely used medications to treat arrhythmias may increase the risk of developing cancer, especially in men and people exposed to high amounts of the drug. That is the conclusion of a new retrospective study published early online in CANCER, a peer-reviewed journal of the American Cancer Society. The study's results indicate that a potential link between amiodarone and cancer warrants further investigation.

Researchers from the UK determined that developmental delays are present in children within six weeks following convulsive status epilepticus (CSE)—a seizure lasting longer than thirty minutes. The study appearing today in Epilepsia, a journal published by Wiley on behalf of the International League Against Epilepsy (ILAE), suggests that neurodevelopmental impairments continue to be present one year after CSE.

NEW ORLEANS, April 7, 2013 — Why does the "65-degree egg" and its "6X°C" counterparts continue to entice chefs and diners at chic restaurants, when the science underpinning that supposed recipe for perfection in boiling an egg is flawed?

NEW ORLEANS, April 7, 2013 — In a discovery suggesting that odors may have a far more important role in life than previously believed, scientists have found that heart, blood, lung and other cells in the body have the same receptors for sensing odors that exist in the nose. It opens the door to questions about whether the heart, for instance, "smells" that fresh-brewed cup of coffee or cinnamon bun, according to the research leader, who spoke here today at the 245th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society.

WASHINGTON–A novel combination of two drugs has shown anti-cancer activity in patients who had incurable solid tumors and carried a germline mutation in their BRCA genes, Dana-Farber Cancer Institute researchers are reporting at the American Association for Cancer Research annual meeting in Washington, April 6-10.

The findings (abstract LB-202) will be released at a press conference on Sunday, April 7, 2 p.m. ET, and later at an oral presentation on Tuesday, April 9, 2 p.m. ET, in Room 153, in the Washington Convention Center.

WASHINGTON, DC (April 7, 2013)—Women with HIV acquire cancer-causing forms of the human papillomavirus (HPV) that are not included in the current HPV vaccines Gardasil and Cervarix, according to new research from Fox Chase Cancer Center being presented at the AACR Annual Meeting 2013 on Sunday, April 7.

"People with issues in their immune system such as HIV will be at risk of acquiring HPV, as well – and the current vaccine may not fully protect them," says study author Elizabeth Blackman, MPH, research specialist at Fox Chase.

WASHINGTON, DC (April 7, 2013)—Colorectal cancer is the second leading cause of cancer-related deaths in the United States. Once colorectal cancer has spread to other parts of the body, only 11 percent of patients will survive five years from the date of their diagnosis. Most colorectal cancers are adenocarcinomas—cancers that begin in cells that make and release mucus and other fluids. Adenocarcinomas begin as benign tumors called adenomas, which become malignant over time. By treating adenomas before they become cancerous, it could be possible to prevent colorectal cancer.

An international research team has identified seven new gene loci linked to obesity. Researchers were also able to show that the genetic mechanisms that cause extreme obesity are similar to those that cause milder forms of overweight and obesity.

ANN ARBOR—Researchers in the Life Sciences Institute at the University of Michigan have challenged a long-held belief that whitening of skeletal muscle in diabetes is harmful.

In fact, the white muscle that increases with resistance training, age and diabetes helps keep blood sugar in check, the researchers showed.

In addition, the insights from the molecular pathways involved in this phenomenon and identified in the study may point the way to potential drug targets for obesity and metabolic disease.

The global burden of dengue infection is more than triple current estimates from the World Health Organization, according to a multinational study published today in the journal 'Nature'.

The research has created the first detailed and up-to-date map of dengue distribution worldwide, enabling researchers to estimate the total numbers of people affected by the virus globally, regionally and nationally. The findings will help to guide efforts in vaccine, drug and vector control strategies.

A new separation process that depends on an easily-distinguished physical difference in adhesive forces among cells could help expand production of stem cells generated through cell reprogramming. By facilitating new research, the separation process could also lead to improvements in the reprogramming technique itself and help scientists model certain disease processes.
