Giant Thai insect reveals clues to human heart disease Posted: 30 Sep 2016 06:40 PM PDT An electron microscope has been used to capture the first three-dimensional image of a tiny filament, or strand, of an essential muscle that the palm-sized water bug Lethocerus indicus uses to fly. This image shows, for the first time, the individual molecules in the filament in a relaxed state, which is necessary to re-extend muscles.

How cancer's 'invisibility cloak' works Posted: 30 Sep 2016 12:03 PM PDT Researchers have discovered how cancer cells become invisible to the body's immune system, a crucial step that allows tumors to metastasize and spread throughout the body.

New weapon for hard-to-treat bacterial infections Posted: 30 Sep 2016 11:58 AM PDT Health workers may soon have a new weapon in the fight against abscesses -- difficult-to-treat bacterial infections that lead to millions of emergency-room visits every year. Researchers successfully prevented drug-resistant bacteria from forming abscesses, or painful pus-filled lesions, using a peptide, or mini-protein. The peptide worked by disrupting the bacteria's stress response.

As the thermostat goes up, COPD symptoms may worsen Posted: 30 Sep 2016 05:08 AM PDT High indoor temperatures appear to worsen symptoms of chronic obstructive pulmonary disease, or COPD, particularly in homes that also have high levels of air pollutants, according to new research.

Studying therapeutic stool transplantation (fecal microbiota transplantation) Posted: 30 Sep 2016 05:07 AM PDT Patients suffering from infection of the bowel with the Gram-positive bacillus Clostridium difficile often have recurrent infections despite antibiotic treatment. In such cases, the transfer of stool from a healthy donor into the patient's bowel is a safe and effective treatment option, concludes research.

New insights into how drug-resistant bacteria build their defenses Posted: 30 Sep 2016 05:06 AM PDT Improved understanding of the way in which hundreds of different types of disease-causing bacteria operate could help pave the way to tackling their effects, according to leading scientists.

Research targets genes, traits to improve glaucoma screening, prevention, and treatment Posted: 29 Sep 2016 06:52 PM PDT Researchers from the U.S. and India have begun a new collaborative project to identify genetic risk factors and traits related to glaucoma, a leading cause of blindness worldwide. The researchers' goal is to help develop effective screening, prevention, and treatment strategies for glaucoma.

Cardiovascular risk factor prevention should be addressed at all ages Posted: 29 Sep 2016 06:52 PM PDT Older adults can develop cardiovascular risk factors later in life, according to a study. Investigators found that the development of risk factors including hypertension, diabetes and high cholesterol remains high in adults over age 45, even extending up to ages over 75 years. In addition, the development of these risk factors was 25 to 100 percent higher in the black population than in the white population.

Scientists find lethal vulnerability in treatment-resistant lung cancer Posted: 29 Sep 2016 06:52 PM PDT A chink has been found in a so-called "undruggable" lung cancer's armor – and located an existing drug that might provide a treatment.

Immediate Breast Reconstruction Reduces Psychological Impact of Mastectomy Posted: 29 Sep 2016 12:20 PM PDT Immediate breast reconstruction (IBR) can avoid some of the psychological effects of undergoing mastectomy for breast cancer, compared to waiting for delayed breast reconstruction (DBR), reports a new study.

Concussions in female high school athletes: Frequent but under-reported Posted: 29 Sep 2016 12:20 PM PDT Nearly half of female athletes participating in high school sports have had a diagnosed or suspected concussion—but most don't report these sports-related injuries to coaches or trainers, reports a study.

Researchers engineer 'micro-pharmacies' in CAR T cells to treat b cell lymphomas Posted: 29 Sep 2016 11:48 AM PDT There has been much recent excitement about immunotherapy and the use of genetically engineered chimeric antigen receptor (CAR) T cells. Historically, CAR T cell immunotherapy has aimed to boost the immune system by giving immune cells the information they need to better recognize tumor cells as foreign and attack them. New work illustrates an untapped potential of CAR T cells to act as targeted delivery vehicles that can function as "micro-pharmacies" for precise therapeutic delivery.

Ocean conditions contributed to unprecedented 2015 toxic algal bloom Posted: 29 Sep 2016 11:48 AM PDT A new paper is the first to connect the unprecedented West Coast toxic algal bloom of 2015 to the unusually warm ocean conditions -- nicknamed "the blob" -- in winter and spring of that year.

Researchers shed light on repair mechanism for severe corneal injuries Posted: 29 Sep 2016 11:47 AM PDT In cases of severe ocular trauma involving the cornea, wound healing occurs following intervention, but at the cost of opaque scar tissue formation and damaged vision. Recent research has shown that mesenchymal stem cells (MSCs) — which can differentiate into a variety of cells, including bone, cartilage, muscle, and fat cells — are capable of returning clarity to scarred corneas; however, the mechanisms by which this happens remained a mystery – until now.

Use of 'large open-ended pipe piles' could lead to lower-cost bridge construction Posted: 29 Sep 2016 11:39 AM PDT A new project has been launched to learn how to use a type of bridge pile often seen in offshore applications. The research could help reduce the cost of bridge building or replacement of aging spans.

Evolution of a species also involves the bacteria it carries Posted: 29 Sep 2016 11:23 AM PDT Animals live in close association with microorganisms, carrying beneficial bacteria while coping with pathogenic infections. Now, a study shows that symbiotic bacteria play a direct role in the evolution of their host, shaping the way it adapts to pathogens.
