Dark Matter Makes a Stunning Comeback
After being written off by a team of European astronomers, dark matter has made a surprise comeback thanks to the training and support of two researchers from New Jersey.
What's the Latest Development?
Last month, a team of researchers found dark matter mysteriously absent in the region around our sun. Having mapped more than 400 stars, spanning a region roughly 26,000 light years in diameter, the European Southern Observatory identified a quantity of material that matched what could be directly observed, such as stars, gas and dust. Because all the matter in the region could be directly accounted for, doubt was thrown onto the strength of the dark matter hypothesis, which posits the new, yet-to-be-observed matter as a mathematical necessity.
What's the Big Idea?
Astronomers from the Institute for Advanced Study in Princeton, NJ, however, now argue that the European team made fundamentally poor assumptions which resulted in incorrect measurements of stellar mass. "The researchers point out the stars within the local neighborhood move slower than the average velocity assumed by the ESO team, in a behavior called asymmetric drift." When the velocity of the selected stars is adjusted, the calculations not only suggest the presence of dark matter but that its density is unusually high around the area of the sun, up to 20% greater than has previously been measured.

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.
Entrepreneur and author Andrew Horn shares his rules for becoming an assured conversationalist.
- To avoid basing action on external validation, you need to find your "authentic voice" and use it.
- Finding your voice requires asking the right questions of yourself.
- There are 3-5 questions that you would generally want to ask people you are talking to.
Sarco assisted suicide pods come in three different styles, and allow you to die quickly and painlessly. They're even quite beautiful to look at.
Death: it happens to everyone (except, apparently, Keanu Reeves). But while the impoverished and lower-class people of the world die in the same ol' ways—cancer, heart disease, and so forth—the upper classes can choose hip and cool new ways to die. Now, there's an assisted-suicide pod so chic and so stylin' that peeps (young people still say peeps, right?) are calling it the "Tesla" of death... it's called... the Sarco!
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.
