New CRISPR system for gene silencing doesn’t rely on cutting DNA

Posted by in categories: biotech/medical, genetics

Scientists from Vilnius University’s (VU) Life Sciences Center (LSC) have discovered a unique way for cells to silence specific genes without cutting DNA. This research, led by Prof. Patrick Pausch and published in the journal Nature Communications, reveals a new way to silence genes that is akin to pressing a “pause” button on certain genetic instructions within cells.

UP Aerospace and Los Alamos lab achieve successful suborbital launch at Spaceport America

Posted by in categories: biological, innovation

In Nijmegen, Netherlands, researchers have installed the world’s first microscope capable of live imaging of biological processes in such detail that moving protein complexes are visible. This new microscopic technique was developed by researchers led by Nico Sommerdijk from Radboud university medical center. As a demonstration of this innovative technique, Sommerdijk is now showcasing how arterial calcification begins.

Induced pluripotent stem cell-derived macrophages as a platform for modelling human disease

Posted by in categories: biotech/medical, health

Macrophages are associated with many human diseases but are challenging to study in vivo. Here, Ginhoux and colleagues discuss how iMacs — macrophages generated from induced pluripotent stem (iPS) cells — can enable disease modelling, including through the use of patient-derived iPS cells and 3D organoid co-culture systems. Ultimately, these iMac-based approaches can improve our understanding of macrophage biology in both health and disease.

Breakthrough Tech Captures and Destroys “Forever Chemicals” in a Single Process — a Game-Changer for Clean Water

Posted by in categories: chemistry, sustainability

Researchers created a single-step device using redox electrodialysis and electrosorption to capture and destroy diverse PFAS chemicals, aiming to address contamination in water and industrial wastewater.

A study from the University of Illinois Urbana-Champaign is the first to introduce an electrochemical method capable of capturing, concentrating, and destroying diverse PFAS chemicals—including the increasingly common ultra-short-chain PFAS—in water, all in a single process. This breakthrough holds promise for tackling the mounting industrial challenge of PFAS contamination, especially within semiconductor manufacturing.

A previous U. of I. study showed that short-and long-chain PFAS can be removed from water using electrochemically driven adsorption, referred to as electrosorption, but this method is ineffective for ultra-short-chain molecules because of their small size and different chemical properties. The new study, led by Illinois chemical and biomolecular engineering professor Xiao Su, combines a desalination filtration technology, called redox electrodialysis, with electrosorption in a single device to address the problems associated with capturing the complete PFAS size spectrum.

Alaska volcanologists continue to track unrest at Mount Spurr

Posted by in category: electronics

Scientists continue to monitor Mount Spurr, a volcano to the west of Anchorage and a huge chunk of the state’s population, after signs of unrest this spring, and again in the fall.

The Alaska Volcano Observatory raised its color code for Spurr to yellow, or “advisory” status, Oct. 16.

The observatory’s Scientist in Charge, Matt Haney, says that was after seismometers picked up an increased number of small earthquakes at the volcano and GPS sensors showed it was swelling up.

Star’s disappearance in Andromeda marks the birth of a black hole

Posted by in category: cosmology

Massive stars about eight times more massive than the sun explode as supernovae at the end of their lives. The explosions, which leave behind a black hole or a neutron star, are so energetic they can outshine their host galaxies for months. However, astronomers appear to have spotted a massive star that skipped the explosion and turned directly into a black hole.

Heavy-ion run at the LHC begins

Posted by in categories: cosmology, particle physics

The Large Hadron Collider (LHC) is like an immensely powerful kitchen, designed to cook up some of the rarest and hottest recipes in the universe, like the quark–gluon plasma, a state of matter known to have existed shortly after the Big Bang. While the LHC mostly collides protons, once a year it collides heavy ions—such as lead nuclei—a key ingredient for preparing this primordial soup.

News at KAIST

Posted by in categories: solar power, sustainability

Existing perovskite solar cells, which have the problem of not being able to utilize approximately 52% of total solar energy, have been developed by a Korean research team as an innovative technology that maximizes near-infrared light capture performance while greatly improving power conversion efficiency. This greatly increases the possibility of commercializing next-generation solar cells and is expected to contribute to important technological advancements in the global solar cell market.

The research team of Professor Jung-Yong Lee of the School of Electrical Engineering at KAIST (President Kwang-Hyung Lee) and Professor Woojae Kim of the Department of Chemistry at Yonsei University announced on October 31st that they have developed a high-efficiency and high-stability organic-inorganic hybrid solar cell production technology that maximizes near-infrared light capture beyond the existing visible light range.

The research team suggested and advanced a hybrid next-generation device structure with organic photo-semiconductors that complements perovskite materials limited to visible light absorption and expands the absorption range to near-infrared.
