Epigenetics opens the door to faster cancer detection
Posted by Paul Battista in categories: biotech/medical, genetics, health
With liquid biopsies, detecting cancer and tracking treatment progress can be as easy as taking a blood test. This is an increasingly popular way of monitoring cancer, because it’s much less invasive than solid tumour biopsies. And liquid biopsies can become even more sensitive if they capture methylation information as well as genetic data.
Usually, liquid biopsies for cancer rely on the detection of small amounts of DNA that are shed from a tumour into the bloodstream. But especially in the disease’s early stages, circulating tumour DNA (ctDNA) levels are very low and point mutations linked to cancer can be easy to miss.
“If we want to develop assays to detect cancer earlier, we need very sensitive detection of these rare tumour fragments,” says Charlotte Proudhon, group leader at the Research Institute for Environmental and Occupational Health in Rennes, France, whose team are among those now developing liquid biopsy methods that include epigenetic markers, such as methylation.

UMD-led Study Could Lead to Lengthened Lives for Patients With Premature Aging Disease
Posted by Omuterema Akhahenda in categories: biotech/medical, genetics, life extension
A new University of Maryland-led discovery could spur the development of new and improved treatments for Hutchinson-Gilford progeria syndrome (HGPS), often simply called “progeria”—a rare genetic disorder with no known cure that causes accelerated aging in children.
Publishing in the journal Aging…
Researchers identify protein that could improve cardiovascular health of those with progeria.

AI-Generated Misinformation is Everywhere. ID’ing It May Be Harder Than You Think
Posted by Omuterema Akhahenda in categories: food, robotics/AI
AI and politics 😳 Artificial though it may be, the concept of “intelligence” doesn’t seem to jibe with a computer-generated image of uniformed cats toting assault rifles.
Yet that visual slur, which supports a debunked story about immigrants in Ohio eating pets, has become a signature image from…
UMD experts explain the emotional pulls and cognitive pitfalls—and how to avoid them.

The Data Dilemma: How Quantum Memory Could Ease the Energy Demands of Computing
Posted by Omuterema Akhahenda in categories: information science, quantum physics, robotics/AI
In a world powered by artificial intelligence applications, data is king, but it’s also the crown’s biggest burden.
As described in the article, quantum memory stores data in ways that classical memory systems cannot match. In quantum systems, information is stored in quantum states, using the principles of superposition and entanglement to represent data more efficiently. This ability allows quantum systems to process and store vastly more information, potentially impacting data-heavy industries like AI.
In a 2021 study from the California Institute of Technology, researchers showed that quantum memory could dramatically reduce the number of steps needed to model complex systems. Their method proved that quantum algorithms using memory could require exponentially fewer steps, cutting down on both time and energy. However, this early work required vast amounts of quantum memory—an obstacle that could have limited its practical application.

Definitely Not Sci-fi: Observing Topologically Ordered Time Crystals with Quantum Processors
Posted by Omuterema Akhahenda in category: quantum physics
The challenge of observing and controlling complex phases of matter has long intrigued researchers, particularly when it comes to non-equilibrium systems like time crystals.
Researchers successfully observed topological time-crystalline order using superconducting qubits on a programmable quantum processor.

AI simulation gives people a glimpse of their potential future self
Posted by Omuterema Akhahenda in categories: robotics/AI, space travel
Have you ever wanted to travel through time to see what your future self might be like?
The user engages with the tool in two ways: through introspection, when they consider their life and goals as they construct their future selves, and retrospection, when they contemplate whether the simulation reflects who they see themselves becoming, says Yin.
“You can imagine Future You as a story search space. You have a chance to hear how some of your experiences, which may still be emotionally charged for you now, could be metabolized over the course of time,” she says.
