From 2011 to 2015, California experienced its worst drought on record, with a parching combination of high temperatures and low precipitation.

Working with human colon cancer cells and mice, researchers led by experts at the Johns Hopkins Kimmel Cancer Center say they have successfully blocked the activity of portions of a protein known as UHRF1 and restored the function of hundreds of cancer-fighting genes that became “misregulated” by the disease.

A label showing added sugars content on all packaged foods and sugary drinks could have substantial health and cost-saving benefits in the United States over the next 20 years, according to a new study published in the American Heart Association’s journal Circulation. 

A number of plant and animal species could find it increasingly difficult to reproduce if climate change worsens and global temperatures become more extreme – a stark warning highlighted by new scientific research.

In a new study that could improve the therapeutic efficacy of deep-brain stimulation (DBS) for psychiatric disorders such as depression, a team of scientists shows that when DBS is applied to a specific brain region, it improves patients’ cognitive control over their behavior by increasing the power of a specific low-frequency brain rhythm in their prefrontal cortex.

Each year at least 2 million Americans are infected with bacteria that cannot be treated with antibiotics, and at least 23,000 of these people die, according to the Centers for Disease Control.

A larger genetic inventory may help explain how certain dangerous bacteria can persist in a hospital environment and continue to infect patients, according to a new study in the journal Proceedings of the National Academy of Sciences.
