Oklahoma, which badly botched a number a number of executions by using experimental methods that were scientifically flawed, has decided to use nitrogen asphyxiation instead. A look at the chemistry and physiology of a more-humane method of capital punishment. 

In the years since AIDS became known to Americans in 1982, it's gone from a certain death sentence to a very manageable disease. And even as good as anti-HIV drugs are today, after nearly four decades of research HIV infection remains incurable. But thanks to two drugs and a bunch of rhesus monkeys, that may soon change. 

More than 2/3 of animals are transported on just four airlines: Alaska, Delta, American, and United. United was responsible for transporting a plurality (27%) of all animals in 2017, so we would expect -- from sheer volume alone -- for more pets to die on United flights. So, the question is, "Do a statistically disproportionate number of animals die on United?" In 2017, sadly, the answer is yes.

Some women who've been diagnosed with early early-stage breast cancer would be well advised to have genetic screening performed. But many are not, and they should be aware that genetic counseling could be crucial and to ask for it if it isn't offered — especially for those considered high risk of developing additional cancers.

A complete hoax was circulated among Russian state-controlled media as legitimate news, and then the Western media fell for it. Sure, some of them provided "caveats." But the point is that Russian propaganda has so infiltrated the public discourse that it appears regularly in mainstream Western media outlets. And that's shocking.

Just the thought makes some cringe. But the truth is that recaptured, treated wastewater is safe to drink. However, as compared to tap and bottled water, how does it taste? Researchers from the University of California, Riverside set to find out, and the results of their study were not what they expected.

Five months after having my son, I'm back to my pre-baby weight. But my BMI still says I'm overweight. Is this true?

What better time to learn more about shuteye than "sleep awareness week"? A new study found that not only are humans sleeping less than other primates, but we're also not getting the sleep that we should be getting. Ugh. Sleep awareness week is exhausting! It might be best to take a nap before reading this one. 

Some of our actions are habits, like putting the key into the ignition as soon as you get in the car. Yet other times we have to think about what we're doing. New research highlights the area of the brain that controls this process, and how it distinguishes between the two categories of actions.

This uniquely American tendency to assign racism where none exists has struck again in yet another bizarre way. And it's absurd to try to make the case that we are racist toward Chinese food, when the number of Chinese restaurants triples those of U.S. cultural icons such as McDonald's and Starbucks.

Some people believe that when you workout, you basically can't drink enough water. "Hydrate!" they say. But that's misleading. As it turns out, certified athletic trainers and knowledgable health professionals say the proper guideline is simple: Drink enough to quench your thirst – and that's all. And that overdoing it can be dangerous.

Yes, it's in its fourth year. But this journal is transforming peer-review of scientific literature. With a double-blind review process, transparency and editorial consensus, eNeuro is an up-and-coming, open-access publication.

Screening tests for colorectal cancer are generally underutilized, and thus chances to decrease deaths from the disease are missed. New research demonstrates that an app, which patients can use on an iPad, increases the use of these screening tests.

There are millions of people receiving information about their DNA, as it pertains to their ancestry and/or health. A new test, for three mutations in two genes associated with higher rates of certain cancers, recently received FDA approval. But when it comes to the "information provided," what does that really mean?

We were pleased to see that we're getting picked up by various media outlets, and in those across the political spectrum.

Our statistical analysis suggests that the further north Americans live, the likelier they may be to drink excessively. Is it due to the long, dark winter nights?

A new study in the British Journal of Clinical Pharmacology suggests increased use and overdosing of the pain reliever and fever-reducing medication during this period. But what explains it?

Three daycare workers in Chicago were arrested and charged with child endangerment after it was learned they fed their charges gummies containing the sleep-inducing supplement melatonin. What's wrong with that? Plenty.

The Centers for Disease Control has been tracking depression for several years. A new report reveals its prevalence among American adults aged 20 and over.

From a physical standpoint, life's late stages don't have to be progressively difficult. A new study by researchers from two British institutions found that adults who regularly exercise – not just several times a week, but also year in, year out – can remain healthy and function as if they were much younger than their actual ages. 

Reflections of a recent, unsettling winter event, along with suggestions on how to avoid unintentional injury.

What turns a relatively minor skin injury into the life-threatening horror show? That would be necrotizing soft tissue infection, otherwise known as a flesh-eating bacterial infection. New research suggests that a lack of antibodies against Streptococcus bacteria is a likely risk factor.

A recent report from the CDC shows about half of millennials aren't getting tested for HIV — a virus that was a sure killer in the 90s, but thanks to advancements in science has become a manageable illness. Still, millennials aren't taken it seriously. Why?

Society told PhD students that the world would be theirs one day. In truth, after six (or more) years of grueling work, PhDs find themselves exhausted, indebted and unemployable. Facing this reality, is it really any wonder there's evidence of a serious mental health crisis among graduate students?

The curator of Unseen Oceans, a new exhibit at New York's American Museum of Natural History, explained that one of the primary reasons oceanic discovery is accelerating is because of significant advances in technology – like robotics, satellite monitoring, miniaturization and high-definition imaging.
