This Tree Is Growing 40 Different Kinds Of Fruit At Once

This single (and quite colorfully blossoming) tree grows 40 different varieties of peaches, plums, apricots, nectarines, cherries, and even almonds — but just how does it do it?

It does it through the process of chip grafting. After sculptor Sam Van Aken bought a failing orchard in upstate New York full of hundreds of different fruit trees, he began the pain-staking process of grafting several of the different varieties together into one tree. Six years later, the result is this 40-fruit bearing tree, which includes some heirloom varieties that are centuries old.

Each fall, millions of monarch butterflies migrate to California and Mexico for winter. North American monarchs are the only butterflies that make such a massive journey (up to 4,830 kilometers/3,000 miles). They use the sun to ensure that they stay on course and on cloudy days Earth’s magnetic field as a kind of backup navigational system. (read more here)

Sometimes evolution makes beautiful animals that move with all the elegance of a finely-honed ballet. Other times… it makes ducks.

A UC Santa Cruz study found that dancers can improve the ability to do complex moves by walking through them slowly and encoding the movement with a cue through ‘marking’.
Researcher Edward Warburton, a former professional ballet dancer, and colleagues (including a UC Irvine collaborator) were interested in exploring the “thinking behind the doing of dance.”
Their findings suggest that marking may alleviate the conflict between the cognitive and physical aspects of dance practice and allow dancers to memorize and repeat steps more fluidly. As Warburton describes:

Marking could be strategically used by teachers and choreographers to enhance memory and integration of multiple aspects of a piece precisely at those times when dancers are working to master the most demanding material.

It’s possible that this area of research can extend to other kinds of activities, like language acquisition. Stay tuned!

A really interesting line of research. We often think of something like dance as mainly being a physical activity, but it requires extreme cognitive control and focus.

Sometimes I just get to tired of people being stubborn when I try to show them that sexism is a thing that exists. In our society. Right now. And they have been raised by a sexist society, so they are more biased to be sexist than not. That’s OKAY. I was sexist too, until I learned.
That’s called being ignorant. It’s okay to be ignorant as long as you choose to learn more when you discover your ignorance!

I just wanna ragequit society and create a safe house for baby animals and spend all day crocheting them little hats

An invisible force at the center of our galaxy
Scientists have theorized that our Milky Way galaxy has a super massive black hole at the center of it, but how did this idea come about?  How do astronomers measure something that has actually never been seen in our telescopes?
Above is an animation of star movements in our galaxy over the past 16 years.  They all orbit around a point that emits no light in our galaxy.  We can measure the mass of these stars and calculate that their orbits require an object with the mass of 4 million Suns.  So far this points to a super massive black hole in our galaxy.

Smithsonian Scientist and Collaborators Revise Timeline of Human Origins

Many traits unique to humans were long thought to have originated in the genus Homo between 2.4 and 1.8 million years ago in Africa. Although scientists have recognized these characteristics for decades, they are reconsidering the true evolutionary factors that drove them. […]

[Smithsonian paleoanthropologist] Richard Potts developed a new climate framework for East African human evolution that depicts most of the era from 2.5 million to 1.5 million years ago as a time of strong climate instability and shifting intensity of annual wet and dry seasons. This framework, which is based on Earth’s astronomical cycles, provides the basis for some of the paper’s key findings, and it suggests that multiple coexisting species of Homo that overlapped geographically emerged in highly changing environments.

“Unstable climate conditions favored the evolution of the roots of human flexibility in our ancestors,” said Potts, curator of anthropology and director of the Human Origins Program at the Smithsonian’s National Museum of Natural History. “The narrative of human evolution that arises from our analyses stresses the importance of adaptability to changing environments, rather than adaptation to any one environment, in the early success of the genus Homo.”
