Mad scientists through the ages have dreamed of holding the world hostage by threatening to destroy the whole thing. Here's how that could work.

New science uncovers how an unlikely culprit, Porphyromonas gingivalis (Pg) -- the bacterium commonly associated with chronic gum disease -- appears to drive Alzheimer's disease (AD) pathology.

Scientists find and test a promising drug that stops cancer by interfering with the cancer cells' metabolism and other circadian-related functions.

Using active genetics technology, biologists have developed the world's first CRISPR/Cas9-based approach to control genetic inheritance in a mammal. The achievement in mice lays the groundwork for further advances based ...

A new study shows that there is a very limited regeneration of cells in the brain of patients diagnosed with multiple sclerosis (MS). These findings underline the importance of treating MS at an early stage of the diseas...

Fresh insights into the types of cells found in the brains of people with multiple sclerosis could help develop improved therapies, research has found. The study focused on cells in the brain that help to repair damage t...

Scientists studying the relationship of telomeres to cancer made a surprising discovery: a cellular recycling process called autophagy -- generally thought of as a survival mechanism -- actually promotes the death of cel...

Normal gut bacteria are instrumental in inducing an immune response in the presence of invading pathogens. However, exactly how commensal bacteria cause CX3CR1+ macrophages in the intestine to protrude their tentacle-lik...

A new study establishes that patients with chronic obstructive pulmonary disease (COPD) face heightened risks of death, critical illness, and hospitalization if they develop the flu and demonstrates the beneficial effect...

Lead exposure in childhood appears to have long-lasting negative effects on mental health and personality in adulthood, according to a study of people who grew up in the era of leaded gasoline. The findings reveal that t...

A major study provides new evidence that emergency C-sections put new mothers at greater risk of experiencing mental health problems after giving birth.

With the UFC set to appear in Prague for the first time this February 23rd, Czech researchers have been getting into the fighting spirit. Participants were unable to predict fighters' MMA score based on 360 degree headsh...

Older patients with a diagnosis of chronic sinusitis -- a disease of the nasal cavity and paranasal sinuses that often persists over many years -- have a unique inflammatory signature that may render them less responsive...

For all its gene-editing prowess, mechanistically CRISPR is a bit like a power tool with a broken "off" switch. Hear me out: the entire CRISPR machinery is designed in a test tube, and once constructed it's always on. Wh...

A new study reports children whose parents divorced when they were teens are less likely to develop depression or use antidepressants as children whose parents spilt up before they were four years old.

Study finds people rate heavier fighters and those with higher anaerobic fitness as more likely to win an MMA match based on their facial features.

Researchers discovered oligodendrocyte neurogenesis is limited in the brains of patients with Multiple Sclerosis. However, oligodendrocytes that survive the autoimmune attack associated with MS may be able to form new my...

Researchers report human milk oligosaccharides, complex sugars in human breastmilk, may change in pregnant women who are taking probiotics.

Researchers report young adults who live in states with liberal policies are more likely to have used cannabis within the last year than those living in more conservative states. However, the rate of cannabis use disorde...

A new study reveals lead exposure during childhood can significantly impact mental health and personality traits later in life. Researchers found exposure to leaded gasoline prior to the 1990s was linked to increased psy...

A new study sheds light on brain cells implicated in multiple sclerosis. Researchers found there are several types of oligodendrocytes, and the ratio of these cells differ significantly in those with MS. The findings cou...

We think the moon formed when a Mars-sized object crashed into the young Earth. The same object could also have brought the carbon and other elements we need for life
