Study: Sharks like jazz over other genres of music
The unpredictable groove of jazz music actually makes jazz the perfect music for sharks because it mimics the unpredictable flop of prey.
Sharks have an incredible keen sense of smell — 3/4 of its brain is dedicated to olfactory sense — but its sense of hearing isn't so bad, either. And in a recent study, it was discovered that sharks like jazz.
I'd like to pause the article, for just a second, to allow you envision sharks in comfy leather chairs, sipping cocktails, and listening to Dave Brubeck. Snapping fins to the beat and smoking cigarettes on the fire escape. If the editors (of which I am one!) haven't edited that out, I'll continue.
There's a reason for this preference to jazz among sharks. When prey is dying, it gives off a kind-of staccato beat as it flops around. The unpredictable groove of jazz music actually makes jazz the perfect music for sharks, who began to associate the music with food and even develop a "taste" (food joke!) for jazz as the test progressed. The sharks did, however, have trouble discerning between classical and jazz when both were played at the same time on opposite sides of the tank. Sure, it'd be pretty funny if the study had preferred the Jaws theme. But sadly that wasn't included in the test.
Similarly, it was found in a 2015 study that sharks like heavy metal for the same reasons that they like jazz. It's unpredictable by design, and largely non-repetitive.
Sharks are incredibly intelligent and some shivers (did you know a group of sharks is called a shivers?) over have learned over time to associate sounds of particular engines, like those of shark cage divers, with food.
Antimicrobial resistance is growing worldwide, rendering many "work horse" medicines ineffective. Without intervention, drug-resistant pathogens could lead to millions of deaths by 2050. Thankfully, companies like Pfizer are taking action.
- Antimicrobial-resistant pathogens are one of the largest threats to global health today.
- As we get older, our immune systems age, increasing our risk of life threatening infections. Without reliable antibiotics, life expectancy could decline for the first time in modern history.
- If antibiotics become ineffective, common infections could result in hospitalization or even death. Life-saving interventions like cancer treatments and organ transplantation would become more difficult, more often resulting in death. Routine procedures would become hard to perform.
- Without intervention, resistant pathogens could result in 10 million annual deaths by 2050.
- By taking a multi-faceted approach—inclusive of adherence to good stewardship, surveillance and responsible manufacturing practices, as well as an emphasis on prevention and treatment—companies like Pfizer are fighting to help curb the spread.

Swiss researchers identify new dangers of modern cocaine.
- Cocaine cut with anti-worming adulterant levamisole may cause brain damage.
- Levamisole can thin out the prefrontal cortex and affect cognitive skills.
- Government health programs should encourage testing of cocaine for purity.
