Foodmakers have removed trans fats from many of their recipes, and they’ll be banned in many foods nationwide in about a year. It’s a policy that could save plenty of lives, according to a study of counties that have already banned trans fats. The study in the journal JAMA Cardiology looked at 11 counties in New York State where trans fats have been banned in restaurants. Researchers found that heart attacks dropped by nearly 8% and strokes by more than 3%, compared to counties that didn’t restrict trans fats.

Diagnosing lung cancer in the future could be as easy as making a quick swab of the nose. A study in the Journal of the National Cancer Institute shows that in people with lung cancer, cells as far away as the inside of the nose are genetically altered. People without cancer don’t have those alterations. Researchers have found 30 genes they could use as biomarkers for lung cancer. The test needs more work before it could be available as a screening test.

And finally, if you’re dieting, the tone of your Tweets give away whether you’ll lose weight. Researchers presenting to a conference of the Association for Computing Machinery say they were able to predict dieting success with 77% accuracy just by reading the dieter’s tweets. People who succeed are more upbeat and focused on the future. Those who fail send tweets that are more anxious.

A lot of people take low-dose aspirin for heart health but a new study shows it may also protect women against breast cancer. The study in the journal Breast Cancer Research shows that a regular dose of baby aspirin cuts breast cancer overall by 16% and reduces “hormone-receptor positive, HER2 negative” breast cancers by 20%. Those are the most common form of breast cancer. Higher aspirin doses taken less often were not protective, nor were other non-steroidal anti-inflammatory drugs such as ibuprofen.

Vitamin D is known as “the sunshine vitamin” because the skin produces it when exposed to the sun. But a new study shows that sunscreen is getting in the way of vitamin D. The study in the Journal of the American Osteopathic Association shows that sunscreen has contributed to nearly a million cases of vitamin D deficiency around the world. Scientists suggest that people should spend between five and thirty minutes twice a week out in the midday sun before they put on sunscreen.

And finally, extra testosterone makes men go with their gut, and they’re often wrong. A study in the journal Psychological Science shows that men who’d been given a dose of testosterone gel performed 20% worse than a control group on brain teasers where a person’s initial guess is usually wrong. Researchers believe the testosterone produced overconfidence so they never thought twice about their answers.
