While obesity has been reliably linked to many serious health problems – such as diabetes, heart disease, and some cancers – there's a minority of obese people who are metabolically healthy. A new study points to physical fitness as being a key component in these folks' avoidance of some of the usual obesity-linked health issues.

You probably haven't had an earache or ear infection since you were a child, but adults are not immune to infections in the middle ear, especially after they've been exposed to the flu.

Bones are not inert objects, but instead living tissue that responds to a host of mechanical forces. So what if the reason some elderly fall and "break" their hip is that – similar to a bridge collapsing from mechanical fatigue – their bones just gave way? 

While Gary Hirshberg is a marketing genius, in a #MeToo world even those on his side of the political spectrum have been calling Stonyfield out for sexism. The vitriol stems from its newest anti-science commercial, one that features little girls – and the message that girls can't understand science.

In what's become an eagerly anticipated tradition, the Bulletin of the Atomic Scientists warns us that we're all moments away from annihilation. The international media uncritically reports this nonsense, even though the Doomsday Clock has been around since 1947. Yet we're still here. Guess there's something wrong with the clock.

Rarely does Lyme Disease manifest itself as a neuro-invasive condition known, in shorthand, as Bannwarth Syndrome. It's a complicated version of Lyme, and when a cluster of five cases surfaced late last summer, all in the upper midwest, a few red flags were raised.
 

When your doctor insists that you must exercise, that's often received as necessary drudgery. But what if that mandate was to go out and play? A new European study found that recreational soccer can lower "blood pressure, fat mass, and LDL cholesterol" regardless of age or gender, and can do so "after only 12 weeks of training." 

As if there aren't enough ridiculous things to study – and worry about. A group in Great Britain thinks that sandwiches are causing the Earth to warm. Now there's a baloney sandwich – if there ever was one.

What these two processes share is baked into the math of each. In fact, in that respect, they're nearly identical. They both involve some stuff (atoms or money) that is either growing or shrinking. And best yet, they both have a magic number. 

A new meta-analysis published in the journal Sleep Medicine found that middle-aged adults who suffered from insomnia, nightmares and regular bouts of broken sleep were more likely to face cognitive impairment in their later years.

Dangerous fentanyl is now part of the emotionally-charged, lethal injection controversy. This has erupted because Nevada wants to combine it with Valium to execute a twice-convicted murderer. Opinions abound. See who's right and who is wrong.

Philadelphia has a program to provide drug users with clean needles, a safe site to inject and referrals for treatment and social services – a first in the United States. But before we accept or reject the mainstream narratives, let's consider some of the evidence municipal lawmakers studied before taking this action.

With a viral video of an Eagles fan being so joyful over his team's advancement to the Sunday's championship game – that he runs into a pole – we thought we'd ask: How healthy is it to be a Super Bowl fan? 

There is an interaction between measuring and what is measured. Heisenberg's Uncertainty Principle is true for medicine and helps explain some confusing and changing health information. 

Researchers found that students who exhibited signs of paranoid thinking – specifically, the tendency to interpret random coincidences as highly meaningful, or to believe others are plotting against them – had a particular genetic profile.

Detecting cancer before it spreads remains one of the priorities of cancer research field. So while we wait for new cancer treatments to be developed, some think that early detection is the new horizon. A new paper in Science presents an improved blood test, known as CancerSEEK.

If all the early hype is true, then Amazon Go, the giant retailer's new high-tech store, is a food shopper's dream. Just think, no money, no credit/debit cards. Just you and your smartphone (with the app, of course). While it's surely a technological wonder, what it's not is a supermarket.

The Ketogenic diet — high fat, low carb — is growing in popularity. That's because participants can see rapid results. Are the benefits worth it? Only if you can swallow the consequences.

Another vaccine against herpes has failed, but this time it wasn't intended for genital herpes. Instead, Astellas and Vical were trying to develop a vaccine for cytomegalovirus, another herpes virus. 

It is immoral and reckless to leave drugs within the reach of children. That five kids were poisoned makes grandpa, who had a medical marijuana prescription, an irresponsible pothead.

The rules governing customer risk and the responsibilities of Colorado ski resorts have placed the burden squarely on skiers and snowboarders. So in terms of skier safety, exercising greater caution on the slopes is now even more important than ever before.

It may be the height of the flu season but diagnosing flu remains a challenge for physicians. 

Treating heart disease requires physicians to identify a 70 percent blockage. But it turns out that they overestimate blockages and that results in, perhaps, more procedures than necessary.

Intermountain Health, a Utah-based non-profit, announced it will be leading an effort that controls 450 U.S. hospitals to make a strategic play in the generic drug market. But will fighting a consolidated industry with consolidation reduce drug costs?

Sometimes spoiled foods smell bad, warning us not to eat them. But sometimes contamination with bacteria or degradation because of being held too long or at the wrong temperature aren't obvious. And thus consuming raw foods can be a bit like Russian roulette. A new method —a bioelectronic nose — of testing raw seafood, especially oysters, has been devised and could help prevent at least some cases of food-borne illness.
