JUPITER, FL, August 14, 2014 – An international team led by scientists from the Florida campuses of The Scripps Research Institute (TSRI) and the Mayo Clinic have for the first time successfully designed a therapeutic strategy targeting a specific genetic mutation that causes a common form of amyotrophic lateral sclerosis (ALS), better known as Lou Gehrig's disease, as well a type of frontotemporal dementia (FTD).

Whether pneumonia or sepsis – infectious diseases are becoming increasingly difficult to treat. One reason for this is the growing antibiotic resistance. But even non-resistant bacteria can survive antibiotics for some time, and that's why treatments need to be continued for several days or weeks. Scientists at the Biozentrum of the University of Basel showed that bacteria with vastly different antibiotic sensitivity coexist within the same tissue. In the scientific journal Cell they report that, in particular, slowly growing pathogens hamper treatment.

Although HIV can now be effectively suppressed using anti-retroviral drugs, it still comes surging back the moment the flow of drugs is stopped. Latent reservoirs of HIV-infected cells, invisible to the body's immune system and unreachable by pharmaceuticals, ensure that the infection will rebound after therapy is terminated.

(Boston)-- Researchers from Boston University School of Medicine (BUSM) report that a tumor suppressor pathway, called the Hippo pathway, is responsible for sensing abnormal chromosome numbers in cells and triggering cell cycle arrest, thus preventing progression into cancer.

Cambridge, Mass. – August 14, 2014 – Conventional wisdom holds that the cytoplasm of mammalian cells is a viscous fluid, with organelles and proteins suspended within it, jiggling against one another and drifting at random. However, a new biophysical study led by researchers at Harvard University challenges this model and reveals that those drifting objects are subject to a very different type of environment.

Scientists have altered key biological events in red blood cells, causing the cells to produce a form of hemoglobin normally absent after the newborn period. Because this hemoglobin is not affected by the inherited gene mutation that causes sickle cell disease, the cell culture findings may give rise to a new therapy for the debilitating blood disorder.

PRINCETON, N.J.—The death of a spouse undoubtedly brings with it stress, anxiety and uncertainty. Now, a report by Princeton University's Woodrow Wilson School of Public and International Affairs quantifies this stress, showing how a husband's declining health could put Taiwanese women at risk for health issues.

An enzyme therapy may prevent skeletal abnormalities associated with the genetic disorder neurofibromatosis type-1, Vanderbilt investigators have discovered.

A research team led by Nanyang Technological University (NTU) scientists have made a key finding which is expected to open up improved treatment possibilities for children suffering from leukaemia.

They found that two in three cases of acute lymphoblastic leukaemia, a type of cancer of the white blood cells, may be caused by mutations in one of the two key genes found in children. These genes are however more prevalent in those with Down syndrome.

Researchers from the Copenhagen Center for Glycomics at the University of Copenhagen have studied an important receptor protein called LDLR using new, groundbreaking techniques. The protein plays an important role in the absorption of the bad cholesterol, LDL.

The findings have just been published in the Journal of Biological Chemistry.

WASHINGTON, D.C., August 14, 2014 – Although replicating important findings is essential for helping education research improve its usefulness to policymakers and practitioners, less than one percent of the articles published in the top education research journals are replication studies, according to new research published today in Educational Researcher (ER), a peer-reviewed journal of the American Educational Research Association.

Researchers have discovered that women who had been prescribed aspirin regularly before being diagnosed with breast cancer are less likely to have cancer that spread to the lymph-nodes than women who were not on prescription aspirin. These women are also less likely to die from their breast cancer.

In spite of the many positive aspects of work, some people are unable to detach from it – working excessively and compulsively. These are called workaholics.

Postdoctoral Fellow Cecilie Schou Andreassen and colleagues from the Department of Psychosocial Science at the University of Bergen (UiB) in Norway has been the first to assess workaholism in a nationally representative sample.

In the most comprehensive assesment of its type, UNSW Australia-led research has found that in just four years, the HPV vaccine has resulted in a dramatic drop in genital warts in young Australians from a range of backgrounds, a result that could herald further good news for cervical cancer rates in future.
