Newly Identified Gene Reduces Pollen Number of Plants

Producing fewer sperm cells can be advantageous in self-fertilizing plants. An international study led by the University of Zurich has identified a gene in...

A team develops ‘poisoned arrow’ to defeat antibiotic-resistant bacteria

Poison is lethal all on its own — as are arrows — but their combination is greater than the sum of their parts. A...

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...

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...

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...

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...
