Understanding How Cancer Cells Adapt To Survive Harsh Tumor Microenvironments
A new study investigates the conditions that select for a metabolic adaptation known as the Warburg Effect, whereby malignant cells choose to ferment glucose to lactic acid as a means to produce energy.

Novel Cultivated Meat Created From Sheets of Cells
Researchers have developed a new form of cultivated meat using a method that promises more natural flavor and texture than other alternatives to traditional meat from animals.

Single-Cell Test Uncovers How Drugs Kill Cancer Cells
Researchers have developed a novel method to see, at a single-cell/organelle level, how drugs induce cancer cell death.

How Cells Move and Don't Get Stuck
Cell velocity, or how fast a cell moves, is known to depend on how sticky the surface is beneath it, but the precise mechanisms of this relationship have remained elusive for decades. Now, researchers have figured out the precise mechanics and developed a mathematical model capturing the forces involved in cell movement.

Why Are Queen Bees Failing To Reproduce?
Honey bee health has been on the decline for two decades, with queen bees failing faster than they have in the past in their ability to reproduce. New research offers clues about what’s behind queen bee failure, finding that when sperm viability is low, the expression of a protein known to act against pathogens such as bacteria and viruses is high.

A Multipronged Attack Can Halt Multi-Resistant Bacteria in Their Tracks
Infectious diseases caused by bacteria may be treated with antibiotics. But sometimes, the bacterium becomes resistant to the treatment which results in a long and complicated course of disease. Recent studies have shown that combining several types of antibiotics can effectively prevent resistance.

Simulating Evolution To Understand Phenotypic Switching
Using computer simulations built on reasonable assumptions and conducted under careful control, computational bioscientists can mimic real biological conditions. Starting with the original founding population (ancient phase), they can evolve the population over several thousand generations to develop an intermediate phase, and then evolve that generation another several thousand generations to develop a derived phase.

Computational Tool Differentiates Between Data From Cancer Cells and Normal Cells
Researchers have created a new computational technique to accurately differentiate between single-cell RNA-sequencing data from cancer cells and the variety of normal cells found within tumor samples.

Lungfish Genome Reveals How Aquatic Vertebrates Conquered Land
A team of scientists has broken a new record for sequencing the largest animal genome to date – the Australian lungfish, one of the few living relatives of the first land vertebrates.
