It's become common for vegetarians and environmental activists to criticize animals. Cows, for example, used to be criticized for carbon dioxide production, with manufactured claims like "it takes a gallon of gas to make a pound of beef" but that has long been debunked and CO2 is dropping thanks to natural gas, so anti-science groups have turned toward methane.

While it's true that methane has 23X the warming effect of CO2, it is so short-lived as to be silly from a physics point of view, but so are the anti-vaccine and anti-GMO movements, and those still raise a lot of money for groups. 

Achilles tendon disorders are both common and misdiagnosed, with about 25 percent of ruptures missed during initial examination.

A team of researchers has reported that analyzing circulating tumor DNA (ctDNA) can track how a patient's cancer evolves and responds to treatment. 
This type of blood test -- known as a liquid biopsy -- is less invasive, less costly and less risky than conventional tissue biopsies, which essentially are minor surgeries. Obtaining liquid biopsies could occur more frequently, too, thus providing physicians with up-to-date information about how a patient's cancer might be changing. This, in turn, could help in the selection of the best possible treatments to combat the cancer.

Environmental activists love to harass farmers because, let's face it, protesting farmers is safe. You never see activists protesting the far worse environmental damage done by Mexican cartels raising illegal marijuana. Dead bodies are terrible for fundraising.

But that doesn't mean the damage isn't obvious. A new study has found that the annual rate of poisoning deaths of relatively rare, forest-dwelling fishers (Pekania pennant) rose 233 percent compared to a study in 2012. The toxicants were associated with illegal marijuana farms on public and tribal lands in Northern and Southern California.

One day a few years ago, while working on wasps in a rainforest in Costa Rica, entomologist Kevin J. Loope, a postdoctoral researcher at the University of California, Riverside, began reading about the enigmatic matricidal behavior of some social insects. In most social insects, such as bees, ants and wasps, the workers, which are all female, work their whole lives to help the queen produce new offspring. Yet, in the literature Loope found anecdotal reports of workers killing their queen, presenting a fascinating evolutionary puzzle.

Asthma has become the most common chronic disease in children, and that plus a corresponding increase in modern helicoptering parenting one of the reasons there are so many emergency department visits for asthma in the US.

A new study presented at the American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting has determined that the probability of future acute care visits increased from 30 percent with one historical acute care visit to 87 percent with more than five acute care visits, based on records for more than 10,000 children seen for asthma in a three-year period. It focused on acute care visits which included emergency departments, urgent care centers and inpatient admissions at hospitals.
