Big "scary" asteroid flying between Earth and Moon tonight, 5/15/18
An asteroid about the size of a New York City block is flying between the Earth and the Moon today. How close, though?
An asteroid about the size of a New York City block is flying between the Earth (you may have heard of it) and the Moon (you may have seen it) at about 6pm EST today. That's "pretty damn close" by aeronautic standards.
The moon is about 252,088 miles (405,696 km) away — so about 30 planet Earth's could fit between here and the moon. The asteroid will pass at almost the exact halfway point between the moon and here, about 126,000 miles away. You won't be able to see it with the naked eye. But a hobbyist telescope, pointed in the right direction at the right time, should be able to see it.
The asteroid that wiped out the dinosaurs was 6 miles wide, so in the grand scheme of things this isn't a world-ending space rock — it's worth reiterating that asteroid happened to hit at the "worst possible" place it could have, as only 13% of the land on Earth could create that much dust which is what ultimately wiped out the dinosaurs by effectively forcing a nuclear winter. But while the asteroid that's zinging past us today is only 900ft long, it's still too close for comfort. Consider this: the meteorite that created the Barringer Crater was only 160ft long and created this:
The new version's battery has a shorter range and a price $4,000 lower than the previous starting price.
- Tesla's new version of the Model 3 costs $45,000 and can travel 260 miles on one charge.
- The Model 3 is the best-selling luxury car in the U.S.
- Tesla still has yet to introduce a fully self-driving car, even though it once offered the capability as an option to be installed at a future date.
What makes an excellent educator?
- When it comes to educating, says Dr. Elizabeth Alexander, a brave failure is preferable to timid success.
- Fostering an environment where one isn't afraid to fail is tantamount to learning.
- Human beings are complicated and flawed. Working with those complications and flaws leads to true knowledge.
Drinking home alone in your underwear just might be what you need to be as relaxed as the Finnish.
- Päntsdrunk is the latest trend to come out of Scandinavia and it involves drinking alone at home.
- Finnish writer Miska Rantanen outlines the philosophy in his newest book titled: Pantsdrunk: Kalsarikanni: The Finnish Path to Relaxation.
- Kalsarikänni is a word in Finnish that literally means "drinking at home and alone in your underwear."
We all know sleeping with your ex is a bad idea, or is it?
- In the first study of its kind, researchers have found sex with an ex didn't prevent people from getting over their relationship.
- Instead of feeling worse about their breakup after a hookup, the new singles who attempted sexual contact with their ex reported feeling better afterwards.
- The findings suggest that not every piece of relationship advice is to be taken at face value.
It's hard to imagine such a number. But these images will help you try.
The Mega Millions lottery just passed $1 billion for tonight's drawing.
What does that even look like, when represented by various currencies?
It takes just 6 numbers to win. You can only, however, purchase tickets up until 10:45 ET tonight.
"It's about having employees that are empowered."
Denmark may be the birthplace of the Lego tower, but its workplace hierarchy is the flattest in the world.
According to the World Economic Forum's Global Competitiveness Report 2018, the nation tops an index measuring "willingness to delegate authority" at work, beating 139 other countries.
Want a happy, satisfying relationship? Psychologists say the best way is to learn to take a joke.
- New research looks at how partners' attitudes toward humor affects the overall quality of a relationship.
- Out of the three basic types of people, people who love to be laughed at made for better partners.
- Fine-tuning your sense of humor might be the secret to a healthy, happy, and committed relationship.
Tiny and efficient, these biodegradable single cells show promise as a way to target hard-to-reach cancers.
- Scientists in Germany have found a potential improvement on the idea of bacteria delivering medicine.
- This kind of microtargeting could be useful in cancer treatments.
- The microswimmers are biodegradable and easy to produce.
Metin Sitti and colleagues at the Max Planck Institute in Germany recently demonstrated that tiny drugs could be attached to individual algae cells and that those algae cells could then be directed through body-like fluid by a magnetic field.
The results were recently published in Advanced Materials, and the paper as a whole offers up a striking portrait of precision and usefulness, perhaps loosely comparable in overall quality to recent work done by The Yale Quantum Institute. It begins by noting that medicine has been attached to bacteria cells before, but bacteria can multiply and end up causing more harm than good.
A potential solution to the problem seems to have been found in an algal cell: the intended object of delivery is given a different electrical charge than the algal cell, which helps attach the object to the cell. The movement of the algae was then tested in 2D and 3D. (The study calls this cell a 'microswimmer.') It would later be found that "3D mean swimming speed of the algal microswimmers increased more than twofold compared to their 2D mean swimming speed." The study continues —
More interestingly, 3D mean swimming speed of the algal microswimmers in the presence of a uniform magnetic field in the x-direction was approximately threefolds higher than their 2D mean swimming speed.
After the 2D and 3D speed of the algal was examined, it was then tested in something made to approximate human fluid, including what they call 'human tubal fluid' (think of the fallopian tubes), plasma, and blood. They then moved to test the compatibility of the microswimmer with cervical cancer cells, ovarian cancer cells, and healthy cells. They found that the microswimmer didn't follow the path of bacteria cells and create something toxic.
The next logical steps from the study include testing this inside a living organism in order to assess the safety of the procedure. Potential future research could include examining how effective this method of drug delivery could be in targeting "diseases in deep body locations," as in, the reproductive and gastrointestinal tracts.
