Scientists have identified a unique class of breast cancer cells that lead the process of invasion into surrounding tissues, the first step in the deadly process of cancer metastasis, and have found a way to stop that invasion process in mice.
Two very different recent papers come to a similar conclusion: cyclical, physiologic hormone replacement therapy (HRT) aids memory in postmenopausal women. One paper found native progesterone, as it is in its natural state cycling the body, helps memory early post-menopause. The other paper found cyclic, physiologic, administered estrogen helps memory after induced menopause.
Mothers typically get all the attention, but a new study suggests that the father’s diet before conception may play an equally important role in the health of their offspring.
There is more than meets the eye following even a mild traumatic brain injury. While the brain may appear to be intact, new findings report that the brain’s protective coverings may feel the brunt of the impact.
Men who continued to smoke after a cancer diagnosis had an increased risk of death compared with those who quit smoking after diagnosis, according to a new study.
Researchers are investigating a potential new therapy for autism and other neurodevelopmental disorders by treating gut microbiota with probiotic therapy, which influences autism-like behaviors in a mouse model.
A new report has revealed that the number of people living with dementia worldwide in 2013 is now estimated at 44 million, reaching 76 million in 2030 and 135 million by 2050.
A new brain connectivity study found striking differences in the neural wiring of men and women that’s lending credence to some commonly held beliefs about their behavior.
Stem cells that quell inflammation shortly after traumatic brain injury (TBI) may also offer lasting cognitive gains, says the University of Texas Health Science Center. In a recent article, the team of Children’s Program in Regenerative Medicine Director Charles Cox reported they injected, into the blood of two groups of rats with traumatic brain injury (TBI), human multi-potent adult progenitor cells (MAPCs).
Researchers have used radioimmunotherapy to destroy remaining HIV-infected cells in the blood samples of patients treated with antiretroviral therapy, offering the promise of a strategy for curing HIV infection.
A new study suggests that a diet low in vitamin D causes damage to the brain. The new evidence shows that vitamin D serves important roles in organs and tissue, including the brain.
Cancers that occur in later life could be down to the way our cells age, according to a new paper that says some cancers could be caused by older cells bypassing the switch that tells them to stop growing.
Recent studies have linked hundreds of gene mutations scattered throughout the brain to increased autism risk. Where do you start? Neuroscientists may finally have an answer.
After a mild concussion, special brain scans show evidence of brain abnormalities four months later, when symptoms from the concussion have mostly dissipated, according to new research.
British biochemist Frederick Sanger, who twice won the Nobel Prize in chemistry and was a pioneer of genome sequencing, has died at the age of 95. His death was confirmed Wednesday by the MRC Laboratory of Molecular Biology - which Sanger helped found.
New research has found that women who have taken oral contraceptives for three or more years are twice as likely to suffer from glaucoma, one of the leading causes of blindness which affects nearly 60 million worldwide.
In a move that may end up having major impact on women, a research team has repeatedly made functional eggs— resulting in healthy live births— from adult mouse cells.
A new study has shown that high concentrations of tungsten– as measured in urine samples– is strongly linked with an increase in the occurrence of stroke, roughly equal to a doubling of the odds of experiencing the condition.
Researchers have devised a new way to understand patterns of aneuploidy in tumors and have proposed that the phenomenon is a driver of cancer, rather than a result of it.
Researchers have discovered a novel genetic cause of severe obesity which, although relatively rare, demonstrates for the first time that genes can reduce basal metabolic rate.
When we sleep, our brains get rid of gunk that builds up while we're awake, suggests a study that may provide new clues to treat Alzheimer's disease and other disorders.
Examining 12 major types of cancer, scientists have identified 127 repeatedly mutated genes that appear to drive the development and progression of a range of tumors in the body.
For the first time, neuroscientists have observed the neural activity that appears to produce the disordered thinking that causes delusions or hallucinations in patients with schizophrenia.
In the battle against antibiotic resistant bacteria, McMaster researchers have found resistance itself is a successful pathway for discovering new antibiotic drugs. "In essence, we’ve made resistance useful instead of a scary problem," said Gerry Wright, professor and scientific director of the Michael G. DeGroote Institute for Infectious Disease Research.
