More secondary schooling reduces HIV risk
Longer secondary schooling substantially reduces the risk of HIV infection -- especially for girls -- and could be a very cost-effective way to halt the spread of the virus, according to researchers from Harvard T.H. Chan School of Public Health. In a study in Botswana, researchers found that, for each additional year of secondary school, students lowered their risk of HIV infection by 8 percentage points about a decade later, from 25 percent to about 17 percent infected.

Having a stroke? Where you are makes a huge difference in your treatment
It looks like a crazy quilt spread over the continent. But a new map of emergency stroke care in America shows just how much of a patchwork system we still have for delivering the most effective stroke treatment. And thousands of people a year may end up unnecessarily disabled as a result.

High blood pressure linked to reduced Alzheimer's risk, meds may be reason
A new study suggests that people with a genetic predisposition to high blood pressure have a lower risk for Alzheimer's disease. However, authors conclude the connection may have more to do with anti-hypertension medication than high blood pressure itself.

Braking mechanism identified for cell growth pathway linked to several cancers
Researchers at University of California, San Diego School of Medicine have discovered a self-regulating loop in the Hippo pathway, a signaling channel garnering increased attention from cancer researchers due to its role in controlling organ size, cell proliferation and cell death.

Alzheimer's disease works differently in patients with and without Down syndrome
Researchers at the University of Kentucky's Sanders-Brown Center on Aging have completed a study that revealed differences in the way brain inflammation -- considered a key component of Alzheimer's disease -- is expressed in different subsets of patients, in particular people with Down syndrome and AD.

Researchers uncover epigenetic switches that turn stem cells into blood vessel cells
Researchers at the University of Illinois at Chicago have identified a molecular mechanism that directs embryonic stem cells to mature into endothelial cells -- the specialized cells that form blood vessels. Understanding the processes initiated by this mechanism could help scientists more efficiently convert stem cells into endothelial cells for use in tissue repair, or for engineering blood vessels to bypass blockages in the heart.

A person's diet, acidity of urine may affect susceptibility to UTIs
The acidity of urine -- as well as the presence of small molecules related to diet -- may influence how well bacteria can grow in the urinary tract, a new study shows. The research, at Washington University School of Medicine in St. Louis, may have implications for treating urinary tract infections, which are among the most common bacterial infections worldwide.

Multiple pathways progressing to Alzheimer's disease
UC San Diego School of Medicine researchers report that the amyloid cascade hypothesis, long believed to describe the pathology of Alzheimer's disease, is not a fixed and invariable sequence of events. Rather, early indicators or biomarkers of the neurodegenerative condition vary by individual, making preclinical diagnoses more challenging.

Chloroplast tubes play a key role in plants' immune defense
When plant cells are infected with pathogens, networks of tiny tubes called stromules grow from the chloroplasts to the cell's nucleus and trigger programmed cell death and innate immune responses.

On average, the mother liquor or solvent and its constituents occupy about 50 percent of a macromolecular crystal. Ordered as well as disordered solvent components need to be accurately accounted for in modelling and refinement, often with considerable complexity.

Development of new blood vessels not essential to growth of lymph node metastases
A Massachusetts General Hospital Cancer Center research team reports has found that the growth of metastases in lymph nodes -- the most common site of cancer spread -- does not require the development of new blood vessels, potentially explaining why antiangiogenesis drugs have failed to prevent the development of new metastases.

TSRI team gets new close-up view of key part of Ebola virus life cycle

Redrawing language map of brain
For 140 years, scientists' understanding of language comprehension in the brain came from individuals with stroke. But now they have redrawn that brain map based on new research with individuals who have a rare form of dementia that affects language, primary progressive aphasia. Northwestern scientists discovered language comprehension is in a different neighborhood, providing a more precise brain target for future therapies to restore language.

Wistar scientists pinpoint mutations responsible for ineffective 2014-2015 flu vaccine
Viruses like influenza have the ability to mutate over time, and given that the flu vaccines administered during the 2014-2015 season were largely ineffective at preventing the spread of the flu, it appears the virus that recently circulated had taken on mutations not accounted for when last year's vaccine was developed. Now, researchers at The Wistar Institute identified specific mutations that influenza recently acquired to escape the current vaccine design.

What controls blood flow in the brain?
In a paper published on June 25 in Neuron, Yale University scientists present the strongest evidence yet that smooth muscle cells surrounding blood vessels in the brain are the only cells capable of contracting to control blood vessel diameter and thus regulate blood flow. This basic anatomical understanding may also have important implications for phenomena observed in stroke and migraines.

Penn researchers identify stem-like progenitor cell that exclusively forms heart muscle
Future therapies for failing hearts are likely to include stem-like cells and associated growth factors that regenerate heart muscle. Scientists have just taken an important step towards that future by identifying a stem-like 'progenitor' cell that produces only heart muscle cells.

Calcium uptake by mitochondria makes heart beat harder in fight-or-flight response
In a life-threatening situation, the heart beats faster and harder, invigorated by the fight-or-flight response, which instantaneously prepares a person to react or run. Now, a new study by researchers at Temple University School of Medicine shows that the uptick in heart muscle contractility that occurs under acute stress is driven by a flood of calcium into mitochondria -- the cells' energy-producing powerhouses.

Researchers at the University of Pittsburgh School of Medicine have devised a computational model that could enhance understanding, diagnosis and treatment of pressure ulcers related to spinal cord injury. In a report published online in PLOS Computational Biology, the team also described results of virtual clinical trials that showed that for effective treatment of the lesions, anti-inflammatory measures had to be applied well before the earliest clinical signs of ulcer formation.

Weight loss plus vitamin D reduces inflammation linked to cancer, chronic disease
For the first time, researchers at Fred Hutchinson Cancer Research Center have found that weight loss, in combination with vitamin D supplementation, has a greater effect on reducing chronic inflammation than weight loss alone. Chronic inflammation is known to contribute to the development and progression of several diseases, including some cancers.
