Scientists release newly Accurate Map of all the Matter in the Universe

Analysis combines Dark Energy Survey, South Pole Telescope data to understand evolution of universe. A group of scientists have released one of the most precise measurements ever made of how matter is distributed across the universe.

When the universe began, matter was flung outward and gradually formed the planets, stars and galaxies that we know and love today. By carefully assembling a map of that matter today, scientists can try to understand the forces that shaped the evolution of the universe.

A group of scientists, including several with the Uni...

This Groundbreaking Biomaterial Heals Tissues from the inside out

A beaker with tissue being spun
The biomaterial is based on a hydrogel that Christman’s lab developed. 

The material can be injected intravenously and has potential application in heart attacks, traumatic brain injury and more. A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.

“This biomaterial allows for treating damaged tissue from the inside out,” said Karen Christman, a professor of bioengineering at the University of California...

Superconductivity Switches On and Off in ‘Magic-Angle’ Gaphene

A unique device is made of sandwiched layers, with yellow and purple on top and blue on bottom. The middle layer is dark grey representing 2 layers of graphene, and the inset shows the graphene layers creating a moiré pattern. The device has a central rectangular shape with 7 more rectangular shapes emanating from it.
Caption:MIT physicists have found a new way to switch superconductivity on and off in magic-angle graphene. This figure shows a device with two graphene layers in the middle (in dark gray and in inset). The graphene layers are sandwiched in between boron nitride layers (in blue and purple). The angle and alignment of each layer enables the researchers to turn superconductivity on and off in graphene with a short electric pulse.

Will Machine Learning help us find Extraterrestrial Life?

Will machine learning help us find extraterrestrial life?

Researchers have applied a deep learning technique to a previously studied dataset of nearby stars and uncovered eight previously unidentified signals of interest.

When pondering the probability of discovering technologically advanced extraterrestrial life, the question that often arises is, “if they’re out there, why haven’t we found them yet?” And often, the response is that we have only searched a tiny portion of the galaxy. Further, algorithms developed decades ago for the earliest digital computers can be outdated and inefficient when applied to modern petabyte-scale datasets...
