Are you shocked by this news in the headline? Us here, not so much. But hats off to the Harvard research team for its new approach to tackling gender inequality in medicine. And the researchers did it by getting back to basics: Let the evidence speak for itself. And to a certain extent, it does.

Pandas are picky creatures. Now, it appears that pandas have yet another quirk: minimum area requirements. A new study published in Scientific Reports shows that they prefer about 115 square kilometers (44 square miles) of space. Even though smaller areas of habitat are available, pandas are less likely to live there. 

The innovations of Dr. Henry Heimlich extended well beyond his famed anti-choking maneuver. The Heimlich Chest Drain Valve gets blood and air out of the chest cavity of soldiers shot there. He also developed the Heimlich MicroTrach, a tiny tube providing certain advantages to delivering oxygen into the trachea, and effectively the lungs.   

This "disease" is a somewhat tongue-in-cheek – though still quite real – phenomenon. Often, those who have been awarded a Nobel gain infamy for saying and believing incredibly stupid things, some of which are quite delusional. Mr. Krugman, the Nobel Prize-winning economist and columnist, is the newest inductee into this dubious club.

18% attrition is a waste of our teaching resources and creates unwarranted stress for our physicians in training.
I was drawn to the article because I was in fact part of that attrition ... I spent a great year in Vermont, growing up

Lost in the synthetic-natural debate is something that actually matter. It is called semisynthesis, and it has saved many lives. Here's how it works. 

Even if you have healthy, adult teeth and gums your dentist may recommend X-rays be taken every year. The dental profession, however, says otherwise. Annual preventive X-rays, called bitewings, for healthy dental patients are not necessary, according to the American Dental Association.

Rice goes with chicken. Rice goes with shrimp. Rice goes with beans, and with Chinese food, too.
But R.I.C.E. is also the most essential serving for ankle sprains, yet for one in two of the millions of Americans who are annually hobbled by a misstep, this recuperative dish is not even on their post-injury menu. 
The well-known acronym stands for the four-step treatment that should be administered following any ankle injury:

It's a longstanding myth that suicides increase during the holiday season. Regardless, suicide is a major public health threat impacting all ages, careers, genders, and socioeconomic strata at alarming rates – throughout the calendar year.

You better hope that Santa doesn't leave you lipstick under the tree. Because if he does, according to the Environmental Working Group, you'll never see Easter.

On the 12th Day of Christmas ACSH gave to me 12 swimmers cupping....
 

To start the second week of our Christmas song, we're presenting seven wacky weight-loss diets — ranging from blood types to tapeworms — that have all reached fad proportions at some point. Read them ... and avoid them!

'Twas The Night Before Christmas, ACSH-style ... 

Dr. Kabat, a cancer epidemiologist at New York's Albert Einstein College of Medicine, explains how we are scared of the wrong things – and why. A compelling read, and a must for anyone wanting to take a critical look at the mass of conflicting information we're constantly bombarded with.

When submitting a scientific manuscript to a journal for review, it's usually safe to say that the worst possible outcome is that it will be rejected. However, a far worse fate is indeed possible – plagiarism – and it happened to Dr. Michael Dansinger. 

Do you "hold the fries?" You might want to if your pants buttons start blowing off. But don't do so because of a deep-fried, phony chemical scare: acrylamide. 

A new study published in JAMA details the U.S. county-level trends in mortality rates for major causes of death. While a bit flawed, it's a step in the right direction as regional health disparity is often way more vital to informing policy than national tendencies.

The Food and Drug Administration told Swedish Match that its snus tobacco product will not receive a MRTP designation, as a Modified Risk Tobacco Product. Snus, a small packet of moist tobacco used orally, is popular in Sweden, which has a substantially lower rate of cigarette-related death and disability than other European Union nations.

By now, anyone even slightly versed in health issues understands that cigarette smoking can irretrievably damage the lungs — whether via lung cancer or other disease processes. Even those who've never smoked may develop these conditions. A recent study indicates that never-smoking women are more likely to develop COPD than never-smoking men.

It is that time of year, and some will talk about fire safety around Christmas trees. But why no mention of the possible dangers in celebrating Chanukah – which begins on Dec. 24 and ends on Jan. 1? Let's fix that. 

How about an invention that will benefit everyone? 
They don't come along very often, but with a little luck Dr. George Bonheyo (1) and his group at the Department of Energy's Pacific Northwest National Laboratory (PNNL) might have something very big on their hands—a novel way to clean up oil spills, with the aid of chemically modified sawdust.
