The full recording of Parnia’s Lab’s premiere film, Rethinking Death: Exploring What Happens When We Die. In Rethinking Death, scientists, physicians, and survivors of cardiac arrest explore the liminal space between life and death, breaking down these stunning scientific breakthroughs to tell the remarkable, scientific story of what happens after we die.

In a paper published in Science Jan. 18, scientists Chad Mirkin and Sharon Glotzer and their teams at Northwestern University and University of Michigan, respectively, present findings in nanotechnology that could impact the way advanced materials are made.

The paper describes a significant leap forward in assembling polyhedral . The researchers introduce and demonstrate the power of a novel synthetic strategy that expands possibilities in metamaterial design. These are the unusual materials that underpin “invisibility cloaks” and ultrahigh-speed optical computing systems.

“We manipulate macroscale materials in using our hands,” said Mirkin, the George B. Rathmann Professor of Chemistry at the Weinberg College of Arts and Sciences.

The random nature of genetic mutation implies evolution is largely unpredictable. But recent research suggests this may not be entirely so, with interactions between genes playing a bigger role than expected in determining how a genome changes.

It’s known that some areas of the genome are more likely to be mutable than others, but a new study now suggests a species’ evolutionary history may play a role in making mutations more predictable too.

“The implications of this research are nothing short of revolutionary,” says University of Nottingham evolutionary biologist James McInerney.

Give people a barrier, and at some point they are bound to smash through. Chuck Yeager broke the sound barrier in 1947. Yuri Gagarin burst into orbit for the first manned spaceflight in 1961. The Human Genome Project finished cracking the genetic code in 2003. And we can add one more barrier to humanity’s trophy case: the exascale barrier.

The exascale barrier represents the challenge of achieving exascale-level computing, which has long been considered the benchmark for high performance. To reach that level, however, a computer needs to perform a quintillion calculations per second. You can think of a quintillion as a million trillion, a billion billion, or a million million millions. Whichever you choose, it’s an incomprehensibly large number of calculations.

On May 27, 2022, Frontier, a supercomputer built by the Department of Energy’s Oak Ridge National Laboratory, managed the feat. It performed 1.1 quintillion calculations per second to become the fastest computer in the world.

ABC News anchor Robin Roberts was brought to tears on Thursday while reporting on a new cancer treatment breakthrough. The story was about a new means of helping cancer patients find donors for blood stem cell transplants – something that Roberts herself had to deal with during her own cancer battle and subsequent health issues. She shed tears thinking of families who will not have to worry as much as she did.

Roberts presented this story along with Good Morning America co-hosts George Stephanopoulos and Lara Spencer. They explained how patients previously had to find a near perfect match for a blood stem cell transplant. This was a particular issue for people of color, but this new breakthrough more than doubles their chances of finding a match. They illustrated the effects with the real-life story of a girl who recently survived a cancer diagnosis that would have been much more dangerous beforehand. Roberts explained how broadening the list of potential donors can be so helpful – and can improve the mindsets of patients and their families as well.

Researchers from the School of Biomedical Engineering & Imaging Sciences have published a new study exploring the use of positron emission particle tracking (PEPT) in a living subject for the first time.

PEPT technology allows for the 3D localization and tracking of a single radioactive particle within large, dense, and/or optically opaque systems, which is difficult to study using other methodologies. The technology is currently used to study flows within complex mechanical systems such as large engines, industrial mixers, etc., but has not yet been translated for use in .

PEPT has previously been an unexplored area in biomedical imaging due to the lack of methods to isolate and radiolabel a single particle of a small enough size and with enough radioactivity which to would enable it to be injected and detected in a living subject.
