Scene: The happy-hour office party.

Your boss is relaxed, drink in hand. A little liquid courage of your own, and you approach her, taking a shot at an opportunity to impress. You open with a quip. She chuckles.

But does she really mean it? Or is she faking?

Only one-third of people can tell the difference between a fake laugh and the real deal, according to a study by Greg Bryant, a professor of communication at University of California, Los Angeles.

Don't Salmon, Don't Shoal: Learning The Lingo Of Safe Cycling

What's that salmon doing in the bike lane?

Alec Baldwin, you were salmoning!

The actor was ticketed in New York on Tuesday for riding his bicycle the wrong way on a one-way street.

Cyclists use the term "salmoning" to describe a biker going against the stream on a one-way bike lane. Surely the definition can be broadened to include Baldwin's infraction.

If Polar Bears Can Eat A Ton Of Fat And Be Healthy, Why Can't We?

Lots of swimming in icy seas may have helped bears evolve to eat a high-fat diet yet remain healthy.

If you were a bear and wanted to make a go of it in the frozen North (think polar bear, of course), what would you need to survive?

White fur would help, to help you sneak up on prey. Also plenty of body fat to stay warm. And you'd need great stamina to swim many miles from one ice floe to the next.

And there's another important trait, researchers reported Thursday: Polar bears have genes that help them live on a diet that's overloaded with fat — without suffering the sorts of human diseases that typically come with a diet of that sort.

Less Nutritious Grains May Be In Our Future

Wheat fields like this one could yield wheat with less zinc and iron in the future if they are exposed to higher levels of CO2, according to the journal Nature.

In the future, Earth's atmosphere is likely to include a whole lot more carbon dioxide. And many have been puzzling over what that may mean for the future of food crops. Now, scientists are reporting that some of the world's most important crops contain fewer crucial nutrients when they grow in such an environment.

Doctors Think The Other Guy Often Prescribes Unnecessary Care

She ordered the test, not me.

Three out of four physicians believe that fellow doctors prescribe an unnecessary test or procedure at least once a week, a survey released Thursday finds.

The most frequent reasons that physicians order extraneous — and costly --medical care are fears of being sued, impulses to be extra careful and desires to reassure themselves about their assessments of patients, the survey said.

'Provocative' Research Turns Skin Cells Into Sperm

New research could be promising for infertile men. Scientists were able to make immature sperm cells from skin cells. Their next challenge is to make that sperm viable.

Scientists reported Thursday they had figured out a way to make primitive human sperm out of skin cells, an advance that could someday help infertile men have children.

"I probably get 200 emails a year from people who are infertile, and very often the heading on the emails is: Can you help me?" says Renee Reijo Pera of Montana State University, who led the research when she was at Stanford University.

Powerful Narcotic Painkiller Up For FDA Approval

Morphine and oxycodone (the active ingredient in Oxycontin) are strong narcotic pain relievers on their own. Moxduo, a drug now up for FDA approval, would combine morphine and oxycodone in a single capsule.

The Food and Drug Administration is trying to decide whether to approve a powerful new prescription painkiller that's designed to relieve severe pain quickly, and with fewer side effects than other opioids.

While some pain experts say the medicine could provide a valuable alternative for some patients in intense pain, the drug (called Moxduo) is also prompting concern that it could exacerbate the epidemic of abuse of prescription painkillers and overdoses.

Scribes Are Back, Helping Doctors Tackle Electronic Medical Records

Medical scribe Connie Gayton keeps the electronic records, allowing orthopedic surgeon Devesh Ramnath to focus on his patients.

Originally published on Mon April 21, 2014 9:43 am

Like many other doctors across the country, Dr. Devesh Ramnath, a Dallas orthopedic surgeon, recently made the switch from paper to electronic medical records. This meant he no longer had to just take notes when he was examining a patient — he also had to put those notes into the computer as a permanent record.

"I was really focused on just trying to get the information in, and not really focusing on the patient anymore," Ramnath says.

For Those Unable To Talk, A Machine That Speaks Their Voice

Carl Moore, a former helicopter mechanic, was diagnosed with ALS 20 years ago. He has had unusual longevity for someone with ALS but expects someday to rely on his wheelchair and speech-generating device.

It's hard to imagine a more devastating diagnosis than ALS, also called Lou Gehrig's disease. For most people, it means their nervous system is going to deteriorate until their body is completely immobile. That also means they'll lose their ability to speak.

So Carl Moore of Kent, Wash., worked with a speech pathologist to record his own voice to use later — when he can no longer talk on his own.

If you're taking vitamins to guard against cancer or a heart attack, you've got plenty of company.

Nearly half of American adults take a vitamin of some kind each a day. About a third take a multivitamin.

But are they worth it?

For people in good health and without any special nutritional deficiencies, there isn't enough evidence to say it's a good idea — at least when it comes to preventing cardiovascular disease and cancer.

Scientists have gotten close to pinning down the origin of Middle East Respiratory Syndrome, a dangerous respiratory disease that emerged in Saudi Arabia 17 months ago.

It turns out the MERS virus has been circulating in Arabian camels for more than two decades, scientists report in a study published Tuesday.

So far MERS has sickened more than 180 people, killing at least 77 of them — an alarming 43 percent. But scientists haven't been sure where the virus came from or how people catch it.

Tiny Iron Particles Help Find Cancer Without Using Risky Radiation

CT scans are valuable for finding cancers, but deliver a lot of radiation in the process. That's an especially big concern for children.
iStockphoto

Originally published on Fri February 21, 2014 10:20 am

Full body CT scans can save lives by helping detect cancer early. But the scans use high doses of radiation to create their detailed images, which means they also increase patients' risk of developing cancer later on in life.

Children and teenagers are at greatest risk, because they tend to live long enough to develop secondary cancers. And their growing tissues may be more susceptible to radiation.
