In a new mouse study, neonatal exposure to nicotine changed the biochemistry of reward circuitry in the brain. Researchers suggest the same mechanism may be at work in humans.

A novel study of mice aboard a Russian spaceflight may raise an intriguing question for the astronauts of tomorrow: Could traveling in space be bad for your joints? Researchers found early signs of cartilage breakdown in the mice, suggesting that the reduced biomechanical forces of spaceflight are at play on the musculoskeletal system.

New research shows the importance of how the three main river valleys in China contributed to Han genetic diversity.

Almost 3,600 people participated in a European study on the impact of green and blue spaces on mental health and vitality.

Women who have a cardiac arrest outside the hospital setting are less likely to receive resuscitation from bystanders and more likely to die than men, according to new research. Researchers looked at data from nearly 6,000 people who had resuscitation attempts between 2006 and 2012 and found that women were less likely to receive resuscitation […]

Researchers in the UK have developed a new method for evaluating plutonium workers’ historical internal radiation exposure. They focused their efforts on workers employed at the start of plutonium operations at the Sellafield (formerly Windscale) nuclear reprocessing facility in the UK.

Native Americans’ use of fire to manage vegetation in what is now the Eastern United States was more profound than previously believed, according to a researcher who determined that forest composition change in the region was caused more by land use than climate change.

Many ways to approach the Riemann Hypothesis have been proposed during the past 150 years, but none of them have led to conquering the most famous open problem in mathematics. A new article suggests that one of these old approaches is more practical than previously realized.

Scientists may have uncovered a primary method through which cancer cells exist undetected in an organism and received more than $1 million to investigate the potential for novel therapeutics that target and destroy cells in a specific state of tumor dormancy.

If a genetically or synthetically engineered organism gets into the environment, how will we tell it apart from the millions of naturally occurring microorganisms? Recently, the US government and research scientists have identified a need for new tools that can detect engineered organisms that have been accidentally or intentionally released beyond the lab. Chemical engineers […]
