Using a unique combination of nanoscale imaging and chemical analysis, an international team of researchers has revealed a key step in the molecular mechanism...
A new hybrid fungus is found in hospitals and linked to...
From the mythical minotaur to the mule, creatures created from merging two or more distinct organisms – hybrids – have played defining roles in...
Synthetic red blood cells mimic natural ones, and have new abilities
Scientists have tried to develop synthetic red blood cells that mimic the favorable properties of natural ones, such as flexibility, oxygen transport and long...
Odds of edible insects transmitting coronavirus SARS-CoV-2 is negligible
The odds of insects that are produced for food or feed transmitting COVID-19 is negligible. That is the conclusion drawn by a team of...
Small Arctic coastal waterbodies, with big carbon release
Arctic coastal watersheds are some of the most threatened regions on Earth, having undergone substantial climatic, physical and biological changes with the warming of...
Researchers develop biotechnological production process
Plants produce the hormone jasmonic acid as a defence response when challenged. This is how they ensure that their predators no longer like the...
Automatic tabletop machine speed up novel drug development

Sea snakes first entered the marine environment 15 million years ago and have been evolving ever since to survive in its changing light conditions,...
New Method Allows Minimally Invasive Cell Sampling
At any given moment, a variety of dynamic processes occur inside a cell, with many developing over time. Because current research methods for gene...
Exchange of Arms between Chromosomes Using Molecular Scissors
The CRISPR/Cas molecular scissors work like a fine surgical instrument and can be used to modify genetic information in plants. The research teams of...
Women with Neandertal gene give birth to more children
One in three women in Europe inherited the receptor for progesterone from Neandertals – a gene variant associated with increased fertility, fewer bleedings during...
New method reveals where in the cell DNA are at increased...
Researchers at Karolinska Institutet have developed a new sequencing method that makes it possible to map how DNA is organized in the cell nucleus...
Activation maps of neural network model for digital staining of tumors
Tissue biopsy slides stained using hematoxylin and eosin (H&E) dyes are a cornerstone of histopathology, especially for pathologists needing to diagnose and determine the...

Scientists have created the first ever large-scale map of microscopic algae as they bloomed across the surface of snow along the Antarctic Peninsula coast....
Nature-inspired CRISPR enzymes for expansive genome editing
In nature, bacteria use CRISPR as an adaptive immune system to protect themselves against viruses. Over the past decade, scientists have been able to...
Identifying cell types from single-cell RNA sequencing data is now more...
Identifying different types of cells within a tissue or an organ can be very challenging and time-consuming. Methods to identify cell types from single-cell...
Communication between mitochondria and other parts of the cell plays a...
As people get older, they often feel less energetic, mobile or active. This may be due in part to a decline in mitochondria, the...
A New Tool to Map the Flow of Info within Living...
How do cells move? Why do they move? Why do some cancer cells move slowly while others move quickly, causing a cancerous tumor to...
Reactivating an enzyme that promotes repairing age-related DNA damage
MIT neuroscientists have discovered that an enzyme called HDAC1 is critical for repairing age-related DNA damage to genes involved in memory and other cognitive...
Steady research in protein structure paves the way for more efficient...
The recent coronavirus pandemic shows just how quickly a deadly pathogen can sweep across the globe, killing tens of thousands in the U.S. and...
