Testosterone therapy not linked to rise in estrogen levels among transgender men

Testosterone therapy is not associated with a rise in estrogen levels among transgender men, according to a new study led by Boston Medical Center. In fact, the researchers observed an initial decline in estrogen levels, which later stabilized and remained within the normal range during the study's six-year period.

Research reveals why older people struggle to get a good night’s sleep

New research has identified the way age impairs the ability of the circadian clock in mammals to re-set itself when exposed to light, resulting in disruption to sleeping patterns and consequent threats to wellbeing

Antibiotic use linked to higher risk of severe viral disease in mice

People infected with West Nile virus can show a wide range of disease. Some develop life-threatening brain infections. Others show no signs of infection at all. One reason for the different outcomes may lie in the community of microbes that populate their intestinal tracts.

Cell-penetrating 'nanodrills' could be new platform for intracellular drug delivery

Researchers at Oregon State University and Oregon Health & Science University have created new nanomaterials able to cross cell membranes, establishing a novel platform for the intracellular delivery of molecular drugs and other cargo.

Johns Hopkins researchers make great strides in understanding biology behind pulmonary hypertension

Working with cells that line the innermost layer of the blood vessels, Johns Hopkins investigators say they have made a leap forward in understanding the underlying biology behind pulmonary hypertension, a dangerous type of high blood pressure in lungs that ultimately leads to right heart failure and death.

Honeybees may provide new clues to how the human brain works

Researchers from the University of Sheffield have discovered that looking at honeybees in a colony in the same way as neurons in a brain could help us better understand the basic mechanisms of human behavior.

Combination therapy effectively induces tumor cell death and reduces spread of breast cancer

Each day, normal human cell tissues express a protein known as p53 that wages war against potential malignancies. However, between 30 and 40 percent of human breast cancers express a defective (mutant) form of p53 that helps cancer cells proliferate and grow.

Study identifies genetic factors linked to severity of acute viral bronchiolitis

A scientific study conducted at the State University of Campinas (UNICAMP) in São Paulo State, Brazil, has identified genetic factors associated with the severity of acute viral bronchiolitis. The study was supported by the Sao Paulo Research Foundation - FAPESP. Its results were published in the journal Gene.

New study reveals why some visual cues remain subliminal

Understanding conscious perception is a major challenge for neuroscience. A new study published on March 22nd in Science now shows why weak visual stimuli of the same strength are sometimes detected and other times remain subliminal: As the signals travel from visual areas to the prefrontal cortex, fluctuating brain dynamics can make the difference, elevating some signals above the threshold of conscious experience and stopping others in their tracks.

Choline intake during pregnancy increases brain grey and white matter in young pigs

Choline intake during pregnancy can influence infant metabolism and brain development, according to a series of studies from the University of Illinois. Although the role of choline in neurodevelopment has been studied before in rodents, the new research, done with pigs, has more relevance to humans.

Measurement of tumor's metabolic activity could help determine prostate cancer prognosis

A new approach to analyzing prostate gland tissue may help address a major challenge in treating prostate cancer - determining which tumors are unlikely to progress and which could be life threatening and require treatment.

MSU scientists test promising drug to prevent cancer in high-risk patients

Michigan State University scientists are testing a promising drug that may stop a gene associated with obesity from triggering breast and lung cancer, as well as prevent these cancers from growing.

Antibody sweeps away Alzheimer's plaques in mice

Years before people start showing characteristic symptoms of Alzheimer's disease, sticky plaques begin forming in their brains, damaging nearby cells. For decades, doctors have sought ways to clear out these plaques as a way to prevent or treat the disease.

Changing schedules of targeted therapy for melanoma could improve outcomes

Skin melanoma, a particularly insidious cancer, accounts for the vast majority skin cancer deaths and is one of the most common cancers in people under 30.

Researchers propose new approach to look deeper into brain function

To uncover connections between brain regions and specific cognitive functions, neuroscientists have long made extensive use of techniques like functional resonance imaging (fMRI). First introduced in the 1990's, the method allows tracking the brain's activity while a test subject performs a task or responds to stimuli in the MRI scanner.
