LA JOLLA, CA - August 8, 2016 - Scientists at The Scripps Research Institute (TSRI) now have a high-resolution view of exactly how the experimental therapy ZMapp targets Ebola virus.

The new study is also the first to show how an antibody in the ZMapp "drug cocktail" targets a second Ebola virus protein, called sGP, whose vulnerable spots had previously been unknown.

For patients with the most common type of noninvasive breast cancer, routine testing for estrogen and progesterone receptors in tissue taken at the first "needle" biopsy is both unnecessary and wasteful, according to results of a study led by Johns Hopkins pathologists.

The results for people with ductal carcinoma in situ or DCIS were persuasive enough that The Johns Hopkins Hospital last January ended the practice of routinely conducting so-called core needle biopsy hormone receptor testing.

WEST LAFAYETTE, Ind. - Dwarfed plants add color and a diversity of architectures to landscapes and gardens, and a Purdue University undergraduate class discovered a key mechanism that leads to their small stature.Graduate student Norman Best led an undergraduate plant physiology class in an exercise that identified a mutation in a dwarf variety of sunflower, called Sunspot, that keeps the plant short. The eight Purdue students, along with scientists that supported the work, published their results in the Journal of the American Society of Horticultural Science.

Two new studies indicate that health insurance status may impact patients' health outcomes following a diagnosis of cancer. Cancer patients who were uninsured or had Medicaid coverage experienced a variety of disparities -- including being diagnosed at a later stage, receiving less than optimal treatment, and having shorter survival times -- when compared with patients with other forms of insurance. The findings are published early online in CANCER, a peer-reviewed journal of the American Cancer Society.

BOSTON -- Men with testicular cancer who were uninsured or on Medicaid had a higher risk of death from what is normally a curable disease than insured patients, a new study found.

The findings, published in Cancer, a journal of the American Cancer Society (ACS), add to growing evidence that differences in health insurance status can affect cancer outcomes. The researchers analyzed outcomes and insurance status for 10,211 men diagnosed with testicular cancer between 2007 and 2011.

Higher socioeconomic status (SES) is associated with lower ovarian cancer risk in African American women, according to the results of a study by investigators at the Medical University of South Carolina (MUSC) and elsewhere reported online August 3 by the American Journal of Epidemiology. It showed that the risk of ovarian cancer was 29 percent lower among women with a college degree or more compared with those who had a high school degree or less.

Researchers from the Cancer Science Institute of Singapore (CSI Singapore) at the National University of Singapore (NUS), in collaboration with Harvard Stem Cell Institute (HSCI), have discovered a new way in which the development of lung cancer can be stopped. In a study published in the journal Science Translational Medicine in August 2016, the researchers found that inhibiting a protein called BMI1 was able to impair tumour growth in lung cancer.

One of the hottest new materials is a class of porous solids known as metal-organic frameworks, or MOFs. These man-made materials were introduced in the 1990s, and researchers around the world are working on ways to use them as molecular sponges for applications such as hydrogen storage, carbon sequestration, or photovoltaics.

Now, a surprising discovery by scientists in Canada and Russia reveals that MOFs also exist in nature -- albeit in the form of rare minerals found so far only in Siberian coal mines.

Amsterdam, The Netherlands, August 5, 2016 - Studies have shown that obstructive sleep apnea and low nighttime oxygen, which result in oxidative stress, are associated with the progression of non-alcoholic fatty liver disease (NAFLD) in adults. Investigators have now established that these factors may also be important triggers in the progression of pediatric NAFLD to non-alcoholic steatohepatitis (NASH), according to a new report in the Journal of Hepatology.

PHILADELPHIA--(Aug. 5, 2016)--Myeloid-derived suppressor cells (MDSCs) are a population of immune cells that have been implicated in tumor resistance to various types of cancer treatment, including targeted therapies, chemotherapy and immunotherapy. Polymorphonuclear (PMN) cells represent the largest population of MDSCs. However, fully understanding the biology and clinical importance of these cells has been hampered by a lack of markers that set them apart from normal neutrophils.

First study to show ovarian environment changes with age and likely hurts quality of eggsOlder ovaries are scarred and inflamedFindings could result in treatments to preserve fertility by delaying ovarian aging

CHICAGO --- Women's decreased ability to produce healthy eggs as they become older may be due to excessive scarring and inflammation in their ovaries, reports a new Northwestern Medicine study in mice.

PROVIDENCE, R.I. [Brown University] -- A new Brown University study projects that increasing the number of Rhode Islanders treated every year for hepatitis C virus infection (HCV) to about 2,000 by 2020 would reduce cases by 90 percent and prevent more than 70 percent of expected liver-related deaths in the state by 2030.

More moderate increases in treatment such as doubling the number treated each year could reduce death rates by less than 20 percent, the analysis showed.

New lung scanning technology developed at Monash University has the potential to transform treatment for millions of people with lung disease in Australia and around the world.

A four-dimensional lung scanning platform developed at Monash University by Professor Andreas Fouras has been commercialised by his medical technology company 4Dx. The scanning platform is now giving a Monash-led research team new insights into improved treatment.

Marine fisheries catches have been drastically under-reported in the Turks and Caicos Islands in the Caribbean, threatening the marine environment and livelihoods of the local community, reveals a recent study published in the open-access journal Frontiers in Marine Science.

Actual catches on the islands were an alarming 2.8 times, or 86% higher than that reported to the FAO, and this has very troubling implications.

"This new drug could be a game changer for future treatment of asthma" - Professor Chris Brightling, NIHR Senior Research Fellow at the University of Leicester

The first new asthma pill for nearly 20 years has the power to significantly reduce the severity of the condition, a study led by the University of Leicester has found.

The research was funded by Novartis Pharmaceuticals, National Institute for Health Research (NIHR) and the EU (AirPROM), and is described by the lead researcher as "a game changer for future treatment of asthma."
