This month, New York became the 23rd US state to legalize the use of medical marijuana. We examine how scientific research and policy intersect in this complex debate.
Paracetamol - known in the US as acetaminophen - is widely recommended for low-back pain. But a new analysis suggests it performs no better than a placebo in aiding recovery.
A new study shows extracts of rosemary, Mexican oregano, and marjoram contain compounds that can inhibit two enzymes that play a role in insulin secretion and insulin signaling.
Following the death of a man who died of plague after handling an infected animal, the Chinese authorities sealed off part of a city for 9 days.
A new UCSD study on jealousy among dogs indicates the emotion may be hardwired in the brain, evolving to protect social relationships.
New research suggests the odds of adverse childhood experiences are higher in people who have served in the military, compared with those who have no military history.
The safety of the blood thinning drug dabigatran (Pradaxa) has been challenged in an investigation by the BMJ, as has the evidence that led to the drug's approval by regulators.
A genetic basis for heart disease in women is defined in a new study, which suggests that women with a gene variant are more likely to develop heart disease.
A team of Johns Hopkins researchers find that the more multiple chronic medical conditions a person has after retirement age, the shorter their life expectancy.
For asthmatics, 'it's not just what you smell, but also what you think you smell.' Researchers found that just believing an odor is harmful can cause airway inflammation.
Lung cancer has a poor survival rate because it often spreads quickly to other parts of the body. Now scientists have discovered a gene that may stop it.
A fly's hearing can focus on a single sound without amplifying background sound. Now, a team has emulated this in a tiny hearing aid that uses a low power source.
Vitamin D deficiency has been linked to numerous health problems. Now, a new study suggests that people who are vitamin D deficient may be more likely to develop schizophrenia.

A potential breakthrough in a cure for HIV/AIDS may come from a new molecular tool designed to hunt down and 'snip out' the HIV genome from patients' cells.
An international team of researchers has identified 108 genes - 83 of which were previously undiscovered - associated with schizophrenia, potentially shedding light on its causes.
A genetically engineered version of a virus used for smallpox vaccination increases the effects of chemotherapy for patients with cancer of the arm or leg.
A new study suggests targeting the immune response - rather than the virus - may be an effective way for drugs to fight H7N9 avian flu and other highly virulent pathogens.
Researchers discover that FBP1 - an enzyme that controls metabolism - may halt tumor growth in clear cell renal cell carcinoma and is missing in tissue taken from its tumors.
