New drug delivery method can reverse senescence of stem cells
As we age, our bodies change and degenerate over time in a process called senescence. Stem cells, which have the unique ability to change into other cell types, also experience senescence, which presents an issue when trying to maintain cell cultures.....»»
Genes of ancient animal relatives used to grow a mouse: Study reveals hidden history of stem cells
An international team of researchers has achieved an unprecedented milestone: the creation of mouse stem cells capable of generating a fully developed mouse using genetic tools from a unicellular organism, with which we share a common ancestor that p.....»»
Scientists propose drug-free method to combat antibiotic-resistant bacteria
Recent estimates indicate that deadly antibiotic-resistant infections will rapidly escalate over the next quarter century. More than 1 million people died from drug-resistant infections each year from 1990 to 2021, a recent study reported, with new p.....»»
Study uncovers role of tissue viscoelasticity in cell response
To the casual eye, a memory foam mattress would appear to have no relationship to the behavior of cells and tissues. But an innovative study carried out at the Centro de Investigaciones Cardiovasculares (CNIC) in Madrid shows that viscoelasticity—t.....»»
Cross-species transplantation: Generation of rat offspring from ovarian oocytes in mice
The idea of maturing oocytes in the ovary to produce offspring has been implemented in various ways. One such method, ovarian transplantation, is a relatively simple procedure for obtaining eggs, compared to in vitro culture of ovaries and follicles......»»

What Trump Can—And Probably Can’t—Do to Reverse U.S. Climate Policy
The new president-elect can go beyond just pulling out of the Paris Agreement. But it may be more difficult to roll back clean energy policies.....»»
Telescope for NASA"s Roman mission complete, delivered to Goddard
NASA's Nancy Grace Roman Space Telescope is one giant step closer to unlocking the mysteries of the universe. The mission has now received its final major delivery: the Optical Telescope Assembly, which includes a 7.9-foot (2.4-meter) primary mirror,.....»»
Using genetic code expansion to study membrane proteins
Over the years, chemical biology methods have made an important contribution to the study of integral membrane proteins. A key modern approach is genetic code expansion (GCE), which makes it possible to modify proteins directly in living cells to giv.....»»
Bone Marrow Donors Can Be Hard to Find. One Company Is Turning to Cadavers
San Francisco–based Ossium Health has carried out three transplants for cancer patients using stem cells from deceased donors’ bone marrow in recent months......»»
Researchers Give Animal Cells the Ability to Photosynthesize for the First Time

Metagenomic profiling method with enhanced precision uses fewer computing resources
Researchers at Carnegie Mellon University and the University of Toronto have developed a new k-mer sketching metagenomic profiler, called sylph, that allows scientists to analyze genomic data more quickly and precisely than other profilers......»»
Squishy microgels in granular biomaterials confine and direct cell behavior
A simple biomaterial-based strategy that can influence the behavior of cells could pave the way for more effective medical treatments such as wound healing, cancer therapy and even organ regeneration, according to a research team at Penn State......»»
Computational method pinpoints how cause-and-effect relationships ebb and flow over time
A new computational method can identify how cause-and-effect relationships ebb and flow over time in dynamic real-life systems such as the brain......»»
Nanofiber patch for psoriasis treatment has dual release functionality
Researchers at the University of Copenhagen have developed a patch for easier and more effective treatment of psoriasis. The method may also be used in treatment of other inflammatory skin diseases......»»
Low-cost method removes micro- and nanoplastics from water
Researchers at the University of São Paulo (USP) in Brazil have developed a novel nanotechnology-based solution for the removal of micro- and nanoplastics from water. Their research is published in the journal Micron......»»
Researchers identify two primary tree movement patterns that help them survive high winds and prevent damage
Destructive winds during storms and cyclones often cause tree failures, especially through uprooting and stem breakage. However, how trees respond to wind under various forest configurations and weather conditions remains unclear......»»
High-performance inkjet print head enhances bioprinting productivity
Bioprinting is a technology used to create three-dimensional structures, such as human tissues or organs, using bio-inks made of cells and hydrogels. However, conventional inkjet technology has difficulty dispensing bio-inks that are sensitive to tem.....»»
Using CRISPR to decipher whether gene variants lead to cancer
In recent years, scientists have created a range of new methods based on CRISPR-Cas technology for precisely editing the genetic material of living organisms. One application is in cell therapy: A patient's immune cells can be specifically reprogramm.....»»
New CRISPR system for gene silencing doesn"t rely on cutting DNA
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,.....»»
