Far-UVC light can efficiently and safely kill airborne coronaviruses

More than 99.9% of seasonal coronaviruses present in airborne droplets were killed when exposed to a particular wavelength of ultraviolet light that is safe to use around humans, a new study at Columbia University Irving Medical Center has found.

Nanosponges attract coronavirus away from lung cells, study shows

Imagine if scientists could stop the coronavirus infection in its tracks simply by diverting its attention away from living lung cells? A new therapeutic countermeasure, announced in a Nano Letters study by researchers from Boston University's National Emerging Infectious Diseases Laboratories and the University of California San Diego, appears to do just that in experiments that were carried out at the NEIDL in Boston.

Scientists use CRISPR tool to make rapid, precise cuts in genomic material

In a series of experiments using human cancer cell lines, scientists at Johns Hopkins Medicine say they have successfully used light as a trigger to make precise cuts in genomic material rapidly, using a molecular scalpel known as CRISPR, and observe how specialized cell proteins repair the exact spot where the gene was cut.

Transforming spleen to liver could bring new hope for patients suffering from organ shortage

Scientists from Nanjing University and University of Macau have transformed the spleen into a functioning liver in living mice, which could bring new hope for patients suffering from organ shortage worldwide.

Anti-RBD antibodies shown to neutralize active SARS-CoV-2

A new study published on the preprint server bioRxiv* in June 2020 reports the discovery of multiple severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in samples from healthy donors, collected before the pandemic. These antibodies are capable of inhibiting the binding of the spike protein of the virus to the angiotensin-converting enzyme 2 (ACE2) molecule and can neutralize active infection of cells in culture.

Study solves the longstanding mystery of anesthesia

Surgery would be inconceivable without general anesthesia, so it may come as a surprise that despite its 175-year history of medical use, doctors and scientists have been unable to explain how anesthetics temporarily render patients unconscious.

Researchers identify a natural amino acid as potential treatment for polyQ diseases

Familial spinocerebellar ataxia (SCA), Huntington disease, and spinal and bulbar muscular atrophy are inherited neurodegenerative diseases.

Magnetic core-shell iron nanowires can be used for noninvasive medical imaging

Living cells inside the body could be placed under surveillance--their location and migration noninvasively tracked in real time over many days--using a new method developed by researchers at KAUST.

Study shows how normal RAS interacts with mutated RAS in living cells

Many cancer medications fail to effectively target the most commonly mutated cancer genes in humans, called RAS.

A new tool to study and map the intricacies of intercellular signaling

How do cells move? Why do they move? Why do some cancer cells move slowly while others move quickly, causing a cancerous tumor to metastasize and become much more difficult to treat effectively?

New method allows researchers to guide neurons in 3D

Highly complex organisms can arise from a single cell, which is one of the true miracles of nature. Substances known as morphogens have an important role in this development, namely by signalling to cells where they should go and what they should do.
