Jo Cameron gave birth to a child without needing pain killers, it "felt like a tickle". She has unintentionally injured herself due to not being able to feel the pain.
Scientists are also intrigued by Ms. Cameron’s extraordinarily low anxiety level. ... She cannot recall ever having felt depressed or scared.
In retrospect, she sees how her genetic disposition may have aided her at work. After years as a primary-school teacher, she retrained to work with people with severe mental disabilities. Erratic, aggressive behavior never riled her, she said.
But though having this mutation may sound like a dream, there are downsides. One is that she is quite forgetful; prone to losing her keys and her train of thought midsentence. The other is that she’s never felt the “adrenaline rush” that other people talk about, she said.
Music has the power to transform. Lift the spirit. Build connections. Heal. Music can be a greater anxiety-reducer and help people cope with pain more than medication in some cases.
Quote: We may finally have found the long-elusive cause of Alzheimer’s disease: Porphyromonas gingivalis, the key bacteria in chronic gum disease. ... the good news is that a drug that blocks the main toxins of P. gingivalis is entering major clinical trials this year, and research ... shows it might stop and even reverse Alzheimer’s.

Brazilian doctors are reporting the world’s first baby born to a woman with a uterus transplanted from a deceased donor.

A researcher realizes that cancer cells share material via nanotubes. This might help cancer cells spread immunity to chemotherapy.
Zika injections shrank aggressive tumours in fully grown mice, yet left other brain cells unscathed.
Human trials are still a way off, but experts believe Zika virus could potentially be injected into the brain at the same time as surgery to remove life-threatening tumours, the Journal of Experimental Medicine reports.
In the 1960s, the sugar industry funded research that downplayed the risks of sugar and highlighted the hazards of fat, according to a newly published article in JAMA Internal Medicine.
The article draws on internal documents to show that an industry group called the Sugar Research Foundation wanted to "refute" concerns about sugar's role in heart disease. The SRF then sponsored research by Harvard scientists that did just that. The result was published in the New England Journal of Medicine in 1967, with no disclosure of the sugar industry funding.
I just heard about this - viruses are a normal component of our gut biome, and may even play a role in killing "bad" bacteria.

The Disappearing Soldier
The stranger was a 31-year-old infantry captain in the Royal Australian Regiment who'd been diagnosed with post-traumatic stress disorder after returning from Afghanistan two years before. He arrived at 6 p.m. on the one bus that comes through town each day...

Three days later, the news would hit the town paper: A young Australian named Paul McKay had gone missing in the North Country, last seen in Saranac Lake [New York]...

Saranac Lake's police chief at the time...wrote to Paul's banks for statements, urgently explaining that Paul might be missing in the wilderness, and that temperatures were 15 below zero and dropping. As the police knocked on doors in search of clues, the ink froze in their pens, and the people they interviewed were aghast at the idea of anybody being out in that cold...

"As national attention focuses on Flint, Mich. — where lead-contaminated water flowed for over a year to a relatively poor, minority community — new research suggests that across the U.S., communities like these are more likely to be exposed to some of the most intense pollution."

Without this video, I would have died of thirst.

It’s Christmas Day, and you know what that means: time to plumb the depths of the U.S. Consumer Product Safety Commission’s database of emergency room visits. We’re looking for the weirdest, least explicable, and most awkward objects that America has shoved inside its various holes. God bless us, everyone.
