In the largest study of the associations between smoking and cardiovascular disease on cognitive function, researchers found both impair the ability to learn and memorize; and that the effects of smoking are more pronounced among females, while males are more impaired by cardiovascular disease.

A dengue virus vaccine candidate has passed an important milestone, with promising results in animal model testing providing hope to the 390 million people infected every year.

A new strategy for capturing the 3D shape of the human face draws on data from sibling pairs and leads to identification of novel links between facial shape traits and specific locations within the human genome.

Researchers are calling for a 'paradigm shift' in combating airborne pathogens such as COVID-19, demanding universal recognition that infections can be prevented by improving indoor ventilation systems.

Researchers have discovered a new brain circuit underlying curiosity and novelty seeking behavior. Using several innovative techniques, the scientists uncovered a whole path of multiple brain regions that converts curiosity into action in mice.

A new study with zebrafish shows that a deadly form of skin cancer -- melanoma -- alters the metabolism of healthy tissues elsewhere in the body. The research suggests that these other tissues could potentially be targeted to help treat cancer.

Epidemic. Pandemic. These terms have become second nature to us, popping up in everyday conversation, and for good reason -- COVID-19 is the latest pandemic to pose a threat to humanity. But in recent months, far less attention has been paid to another widely spread problem that has been proliferating since the late 1970s: Lyme disease.

Cooperation plays a crucial role in evolution. A team of scientists has now created a new model that shows how different kinds of cooperative strategies among humans develop. Using their unified framework, they show how an individual's experience and the reputation of others influence the emergence of successful cooperation.

New research has found that adolescents and older adults pay less attention to social cues in real-world interactions than young adults.

Neuroscientists examining genetically identified neurons in a songbird's forebrain discovered a remarkable landscape of physiology, auditory coding and network roles that mirrored those in the brains of mammals.

People who work nontraditional work hours, such as 11 p.m.-7 a.m., or the 'graveyard' shift, are more likely than people with traditional daytime work schedules to develop a chronic medical condition -- shift work sleep disorder -- that disrupts their sleep. According to researchers, people who develop this condition are also three times more likely to be involved in a vehicle accident.

A small drug molecule that appears to protect normal tissue from the damaging effects of radiation, may simultaneously be able to boost the cancer-killing effect of radiation therapy, according to a new study.

When a researcher heard from a former colleague at the Centers for Disease Control and Prevention that a 7-year-old girl had died from Rocky Mountain spotted fever as the result of a tick bite, he thought of his own daughter, also 7 years old at the time, and the potentially fatal danger posed to vulnerable populations by tick-borne diseases.

In a new study, researchers evaluated the immunogenicity of COVID-19 mRNA vaccines in pregnant and lactating women who received either the Pfizer or Moderna COVID-19 vaccines, finding that both triggered immune responses.
