The search for a cure to AIDS has partly focused on ways to eradicate infected cells. Now, new research from Karolinska Institutet in Sweden and the University of Pennsylvania in the U.S. shows that this approach may not be necessary for a functional cure. In a study focusing on a […]

For many years, the parents of children with autism have reported that behavioral symptoms diminished when the child had a fever. The fever phenomenon has been documented in at least two large-scale studies over the past 15 years, but the reasons behind it have continued to mystify scientists. Now, a […]

Children who acquired HIV in utero or during birth or breastfeeding did not perform as well as their peers who do not have HIV on tests measuring cognitive ability, motor function and attention, according to a report published online in Clinical Infectious Diseases. The observational study included neuropsychological evaluations of 611 […]

In most cases, your genes have less than five percent to do with your risk of developing a particular disease, according to new research by University of Alberta scientists. In the largest meta-analysis of its kind ever conducted, the researchers examined two decades of data from studies on the relationships […]

As an embryo develops, its cells must learn what to do with the thousands of genes they’ve been equipped with. That’s why each cell comes with a detailed gene-expression manual outlining exactly which genes should be switched on, to what extent, and when. To execute their respective manuals, the cells […]

Male Infertility New mouse model allows researchers to track defective sperm and potentially find ways to correct it. One out of eight couples has trouble conceiving, with nearly a quarter of those cases caused by unexplained male infertility. For the past decade, research has linked that infertility to defective sperm […]

Can’t remember something? Try waiting until later in the day. Researchers have identified a gene in mice that seems to influence memory recall at different times of day and tracked how it causes mice to be more forgetful just before they normally wake up. “We may have identified the first […]

E-cigarette use significantly increases a person’s risk of developing chronic lung diseases like asthma, bronchitis, emphysema or chronic obstructive pulmonary disease, according to new UC San Francisco research, the first longitudinal study linking e-cigarettes to respiratory illness in a sample representative of the entire U.S. adult population. The study also […]

In recent years, researchers all over the world have been seeking a deeper understanding about the impact of people’s gut bacteria—their so-called microbiome—on their health and risk of developing different diseases. Researchers from the National Food Institute, Technical University of Denmark (DTU), in cooperation with Rigshospitalet, have investigated the microbiome […]

For most of our evolutionary history — for most of the time anatomically modern humans have been on Earth — we’ve shared the planet with other species of humans. It’s only been in the last 30,000 years, the mere blink of an evolutionary eye, that modern humans have occupied the […]

The progression of cancer has been studied extensively, and the key steps in this journey have been well mapped, at least in some solid tumors: Lesions to genes that confer risk of cancer accumulate and alter normal cell behaviors, giving rise, scientists believe, to early-stage cancer cells that eventually swamp […]

It starts off small, just a skin blemish. The most common moles stay just that way — harmless clusters of skin cells called melanocytes, which give us pigment. In rare cases, what begins as a mole can turn into melanoma, the most serious type of human skin cancer because it […]
