Drug in the pipeline helps stem cell transplants too

Posted by in category: biotech/medical

An investigational drug in clinical trials for rheumatoid arthritis also prevents a common, life-threatening side effect of stem cell transplants, new research shows.

Studying mice, the researchers found the drug prevented what’s known as graft-versus-host disease, a debilitating, sometimes lethal condition that develops when transplanted stem cells attack the body’s own organs or tissues.

About half of patients receiving donor stem cells develop graft-versus-host disease, which can linger for months or years after their transplants. In some cases, patients die not from their cancer but from the complication itself. Current treatments are not effective.

Meet the Woman Who Wants to Solve the Universe’s Mysteries

Posted by in category: cosmology

Last year Kollmeier was named director of the fifth version of the Sloan Digital Sky Survey, a project that aims to map the universe. The survey, which launches in 2020, will employ telescopes in the Northern and Southern Hemispheres to scan the entire sky. The telescopes will obtain spectra of bright objects in the sky, breaking up that light into component parts. “That’s where the astrophysics is,” says Kollmeier. “That tells you all the chemical abundances. That tells you all the transitions in the objects.” And that’s where she’ll begin to find answers to her questions: How do supermassive black holes grow? Can stars be used as clocks that tell us when and how a galaxy was formed?

Kollmeier didn’t get into astronomy by looking up at the stars. She meant to be a lawyer until she went to what she calls “nerd camp” and learned how to write code to classify stars. “The idea that you could interrogate the universe in this way … I felt like an explorer.” Now she’s going further than she once thought possible.

Bye, black holes: white holes are even weirder

Posted by in category: cosmology

If there is a phenomenon out there that is actually more bizarre than black holes, it has to be white holes. Black holes can’t say that they might be the answer to where so much of the dark matter—and even most of the matter—in the universe is lurking.

The gravitational pull of a black hole is so insanely strong that not even light (so much for being the fastest entity in the cosmos), can defy it. Nothing can save you once you pass the grim point of no return otherwise known as the event horizon. However, Space.com observed that when Einstein predicted the existence of black holes in his theory of relativity, he also predicted the theoretical reverse of these galactic monsters. A white hole would be no threat to objects in space passing dangerously close, nothing can even enter its event horizon.

When black holes devour massive amounts of matter and energy, it is thought that everything which appears to vanish forever actually emerges from a white hole. Exactly where the victims of a black hole come out could be anywhere from another place in this universe to another universe entirely. Theoretical physicist Carlo Rovelli theorized something even stranger linking the two. Black holes result from collapsed stars, but when these astral corpses die, they may actually turn into white holes.

Boston Dynamics (Marc Raibert, CEO)

Posted by in categories: engineering, robotics/AI

This is a talk by Marc Raibert for course 6.S099: Artificial General Intelligence. He is the CEO of Boston Dynamics. This class is free and open to everyone. Our goal is to take an engineering approach to exploring possible paths toward building human-level intelligence for a better world.

Note: Due to technical difficulties, we don’t have a screencast of the slides, and the video of the slides is low resolution. Despite this, I chose to include several parts of the talk that show slides, especially with videos. It’s not optimal, but I hope you learn and enjoy anyway. Thanks for understanding. We’re always learning and improving.

Prosthetic Memory System Successful in Humans, Study Finds

Posted by in categories: biotech/medical, cyborgs, engineering, neuroscience

Scientists at Wake Forest Baptist Medical Center and the University of Southern California (USC) have demonstrated the successful implementation of a prosthetic system that uses a person’s own memory patterns to facilitate the brain’s ability to encode and recall memory.

In the pilot study, published in today’s Journal of Neural Engineering, participants’ short-term memory performance showed a 35 to 37 percent improvement over baseline measurements. The research was funded by the U.S. Defense Advanced Research Projects Agency (DARPA).

Preparations for VLT UT1 first light

Posted by in category: space

Final preparations being carried out in the week before the VLT UT1 First Light. Following successful optical alignment tests, the 8.2-m primary mirror was removed from the first Unit Telescope (UT1). This image shows preparations to move it into the Mirror Maintenance Building (MMB) to be coated with a thin, highly reflective aluminium layer. The cell with the 8.2-m mirror has been detached from the lower part of the telescope tube. (Photo obtained on May 17, 1998).

An Introductory Guide to Understand how ANNs Conceptualize New Ideas (using Embedding)

Posted by in category: neuroscience

Here’s something you don’t hear everyday – everything we perceive is just a best case probabilistic prediction by our brain, based on our past encounters and knowledge gained through other mediums. This might sound extremely counter intuitive because we have always imagined that our brain mostly gives us deterministic answers.

We’ll do a small experiment to showcase this logic. Take a look at the below image:

Full moon tonight & conjunction with Jupiter

Posted by in category: space

Nashville, Tenn. (WKRN) — If you saw the moon Saturday night, you know how bright it was!

Technically, it will be a full moon Sunday at 7:58 p.m. There is something else that is special about Sunday’s night sky.

There is a “conjunction” of the moon with Jupiter Sunday and Monday evenings just after sunset in the southeastern sky. Sunset is at 7:32 p.m.
