"In a place where rainfall averages two inches a year, rocks are being shoved around by mechanisms typically seen in arctic climes."

Two cousins’ stroke of luck has provided the final evidence in solving a mystery of the Racetrack Playa that has long puzzled visitors and scientists: What mechanism moves rocks across flat dirt in the heart of the hottest, driest place on earth?

Fascinating! 

“If all insects on Earth disappeared, within 50 years all life on Earth would end. If all human beings disappeared from the Earth, within 50 years all forms of life would flourish.”

Jonas Salk, Biologist (via aurelle)

The latter scenario is more appealing to be honest.

Q

kmthu asked:

What's the "DO NOT EAT" thing in packaged foods, what's in it and how does it work? Thanks!

A

scishow:

It’s silica gel…an artifical form of silicon dioxide (the same stuff that makes up sand) that has tons of tiny pores that have affinities for water. Silica gel can absorb around 40% of its weight in water. It’s manufactured to be entirely dry and then placed in food or other products that manufacturers don’t want to get moist in humid climates (slightly moist chips are what we in the real world call “stale.”) Water would rather be in the silica matrix than the food matrix, so that’s where it goes, keeping the food nice and dry.

And if you’re wondering why you shouldn’t eat it…it’s just because it’s not technically food. It’s not dangerous though…it’s just fancy sand.

Not dangerous….then i know a couple of people who’ll totally eat silica gel. Heck, even i might give it a try. 😜

This Musical Illusion Will Make You Question Your Own Ears

We’re used to illusions being optical. These visual tricks are designed by magicians and masters of the craft to leave us questioning our own eyes. But it’s quite another thing to be left questioning our ears.

Give the video…a listen, and then let it replay (it should do so automatically). The same notes are being played each time — it’s just the same clip, over and over — but it’s weird how they seem to keep going up in pitch.”

Learn more from the huffingtonpost.

WOW! it works…The pitch increases discernibly with each play. Our brain is one mysterious organ. 

“I love science, and it pains me to think that so many are terrified of the subject or feel that choosing science means you cannot also choose compassion, or the arts, or be awed by nature. Science is not meant to cure us of mystery, but to reinvent and reinvigorate it.”

Robert M. Sapolsky (via utcjonesobservatory)

Exactly!

An article about my cousin, Meghana Sreevatsava appeared recently on India Abroad, a weekly newspaper published in New York City.

This article throws a bit of light on the kind of work she has done, and is still doing in various parts of the world. It takes a special kind of person to do what she does. Not everyone on this planet is working towards improving the lives of total strangers.

Wanted to a trio of famous astrophysicists as an art card set: Carl Sagan, Neil deGrasse Tyson, and Stephen Hawking.  Might do more later, but I really wanted to have these three to start. :)

These are so well done.  kevinbolk:

Coming soon: SciNote.org, launched by entrop-e, shychemist, and geogallery, is Tumblr’s project for promoting science education around the world.

At SciNote, we believe that science shouldn’t just be reading about the ideas of people with PhDs and Nobel Prizes. We believe that science is an active process of asking questions and finding answers.

That’s why we, at SciNote, want to hear from you. We want to ponder the interesting questions you pose and get excited with you over the cool science you see in your world.

SciNote will feature the best of the Tumblr science community, and we will compile and publish the top posts from every year in the form of a magazine available both digitally and in print. Think of SciNote magazine as the Tumblr science magazine.

We hope to celebrate our launch by featuring some of the coolest science from around Tumblr. So before we launch SciNote, we would like to collect 25 science posts and/or questions from you, including:

  • the most interesting science news you have come across
  • questions you’ve always wanted to ask
  • fascinating facts that you’ve learned
  • pictures of nature and/or science that you’ve taken
  • cool research that you’ve participated in
  • any other science-related thing you’d like to tell us!

So please:

  1. Submit posts or ask questions to be featured on our blog and for an opportunity to be published in SciNote magazine.
  2. Follow our blog at SciNote.org.
  3. Read more about our project here.
  4. If you’re interested, apply to join our staff here.
  5. Reblog this post so that we can collect 25 posts and launch our project as soon as possible!

Thank you all and happy science!

This is a great project. I’m so glad to be part of the Tumblr community. Proud of all the people involved. KUDOS! 👍

These will crack you up. I’m sure about that.

Want to watch something really scientific about Sharks? If yes, then look no further than the roughly 20 minutes of programming put out by the awesome team behind the thebrainscoop.

It is a really good alternative to the sensationalism and mistruths purveyed by the Discovery Channel.
