Scientists identified the specific proteins secreted by the parasite Toxoplasma gondii that cause the immune system in mice to attack established ovarian tumors. The study, led by David Bzik of the Geisel School of Medicine at Dartmouth in Hanover, New Hampshire, is published on July 22 in PLOS Genetics.

A simple and inexpensive therapy is equally as effective at treating depression as the "gold standard" of Cognitive Behavioural Therapy (CBT), a largescale study has concluded.
A simple and inexpensive psychotherapy or talking therapy known as behavioural activation (BA) is as effective at treating depression in adults as the gold-standard cognitive behavioural therapy (CBT), and can be delivered by non-specialist staff with minimal training at far less cost, according to new research published in The Lancet.
(Toronto - July 21, 2016) Since the discovery of their true nature 140 years ago, lichens have been the poster children for symbiosis. In the textbook definition of a lichen, the filaments of a single fungus provide protection for photosynthetic algae or cyanobacteria, which in turn provide food for the fungus.
But 140 years after the term "symbiosis" was coined to describe lichen, it turns out there's a third party involved in the relationship - a yeast that may help provide the structure found in large "leafy" and "branching" lichens.
ST. LOUIS -- The combination of two plant compounds that have medicinal properties - curcumin and silymarin - holds promise in treating colon cancer, according Saint Louis University research published in the June 23 issue of the Journal of Cancer.
Curcumin is the active ingredient in the spice turmeric, which is present in spicy curry dishes, and silymarin is a component of milk thistle, which has been used to treat liver disease.
Scientists have identified three types of vaccine-induced antibodies that can neutralize diverse strains of influenza virus that infect humans. The discovery will help guide development of a universal influenza vaccine, according to investigators at the National Institute of Allergy and Infectious Diseases (NIAID), and the National Human Genome Research Institute (NHGRI), both part of the National Institutes of Health (NIH), and collaborators who conducted the research. The findings appear in the July 21st online edition of Cell.
A new scientific study has characterized a checkpoint protein that allows certain brain tumor cells to avoid the immune system. Tumors regularly avoid detection by decorating themselves with proteins that mimic those found on healthy cells. This protective shield allows them to grow undetected, often with deadly results. Brain tumors contribute to approximately 17,000 deaths annually with over 4,600 children newly diagnosed each year, according to the American Brain Tumor Association.
A team of researchers based in Israel and the US has found a mathematical resemblance between swarm dynamics and gravitational interactions. The study, which has just been published in the New Journal of Physics, could provide a big leap forward in understanding the mass movement of flying insects.
A multicenter team of researchers led by Barbara Murphy, MD, of the Icahn School of Medicine at Mount Sinai has identified a panel of genes which can help predict whether a transplanted kidney will later develop fibrosis, an injury which can cause the organ to fail. Their results were published in the July 21 edition of Lancet.
Human childbirth is not only unpleasant, it's also assumed to take a toll on women's health, even while women have a greater life expectancy. A new study led by UC Santa Barbara researchers, however, finds that indigenous women in the Bolivian Amazon with some of the highest birth rates in the world today experience negligible health costs from their intense reproductive effort.
Each year, approximately 700,000 people die from drug-resistant bacterial infections. A study by UCLA life scientists could be a major step toward combating drug-resistant infections.
The research, reported in the journal Royal Society Interface, found that combinations of three different antibiotics can often overcome bacteria's resistance to antibiotics, even when none of the three antibiotics on their own -- or even two of the three together -- is effective.
Survey data reveals a high degree of medical consensus that shaking a young child is capable of producing subdural hematoma (a life-threatening pooling of blood outside the brain), severe retinal hemorrhage, coma or death, according to a study published in The Journal of Pediatrics.
A new protein which will help scientists to understand why nerve cells die in people with Alzheimer's disease has been designed in a University of Sussex laboratory.
In people with Alzheimer's, Amyloid-beta (Abeta) proteins stick together to make amyloid fibrils which form clumps between neurons in the brain. It's believed the build-up of these clumps causes brain cells to die, leading to the cognitive decline in patients suffering from the disease.
A UBC professor is suggesting government policy makers and advisors need to do a re-think when it comes to giving validity to reports coming across their desks.
Carey Doberstein, an assistant professor of political science at UBC's Okanagan campus, recently published an experimental study of public sector workers and determined that many give a written report or study purported to be from a university more credibility than one from a think-tank or advocacy group.
Lincoln, Nebraska, July 22, 2016 - No one knows exactly how it happened. It may have entered through a cut or bite wound, the blood of a chimpanzee seeping into an exposed fingertip or forearm or foot.
But in the early 1900s, probably near a West African rainforest, it's thought that a hunter or vendor of bush meat - wild game that can include primates - acquired the first strain of a simian immunodeficiency virus that virologists consider the ancestor of HIV.
