A Gene from Ancient Bacteria Helps Ticks Spread Lyme Disease

One reason ticks spread Lyme disease so well goes back to a unique evolutionary event. Researchers discovered that an antibacterial enzyme in ticks, Dae2, protects them from bacteria found on human ...

Inhaled Vaccine Induces Fast, Strong Immune Response in Mice and Non-Human Primates

Researchers demonstrate in a new study that a phage-based inhalation delivery system for vaccines generates potent antibody responses in mice and ...

Cataloging Nature's Hidden Arsenal: Viruses That Infect Bacteria

A new approach for studying phage-bacteria interactions will help scientists study the intricate offensive and defensive chemical tactics used by parasite and host. These microscopic battles have ...

A Simple Rule Drives the Evolution of Useless Complexity

A new study has shown that elaborate protein structures accumulate over deep time even when they serve no purpose, because a universal biochemical property and the genetic code force natural ...

Magnesium Contact Ions Stabilize the Macromolecular Structure of Transfer RNA

In cells transfer RNA (tRNA) translates genetic information from the encoding messenger RNA (mRNA) for protein synthesis. New results from ultrafast spectroscopy and in-depth theoretical calculations ...

Understanding COVID-19 Infection and Possible Mutations

The binding of a SARS-CoV-2 virus surface protein spike -- a projection from the spherical virus particle -- to the human cell surface protein ACE2 is the first step to infection that may lead to ...

Research Team Invents Novel Light-Controlled Contamination-Free Fluidic Processor for Advanced Medical and Industrial Applications

A mechanical engineering research team has invented a novel light-controlled, contamination-free fluidic processor, which can serve as a useful tool to greatly reduce the risk of infection of ...

New CRISPR-Based Test for COVID-19 Uses a Smartphone Camera

In a new study, a team of researchers outlines the technology for a CRISPR-based test for COVID-19 that uses a smartphone camera to provide accurate results in under 30 ...

Findings About Cilia on Cells of the Vessel Wall May Be Relevant for Diabetes Treatment

A new study shows that primary cilia, hair-like protrusions on endothelial cells inside vessels, play an important role in the blood supply and delivery of glucose to the insulin-producing beta cells ...

'Off Switch' During Error-Prone Cell Cycle Phase May Fix CRISPR's Unwanted Changes Problem

Turning off gene-editing until it reaches cell cycle phases where more accurate repairs are likely to happen offers a promising fix to CRISPR-Cas9's problem with unwanted genetic ...

Scientists Took a Rare Chance to Prove We Can Quantify Biodiversity by 'Testing the Water'

While extraction of DNA from water samples provides a convenient and non-invasive way to study aquatic biodiversity, reliable evidence that this approach is accurate enough to estimate the number of ...

How Bean Plants Fend Off Famished Foes

Scientists have discovered that cowpeas -- a type of bean plant -- harbor receptors on the surface of their cells that can detect a compound in caterpillar saliva and initiate anti-herbivore ...

New DNA Modification 'Signature' Discovered in Zebrafish

Researchers have revealed a previously unknown DNA modification in zebrafish - one of human's distant evolutionary ...

Advancing Gene Editing With New CRISPR/Cas9 Variant

Researchers report the ability to improve safety and efficacy using a CRISPR-Cas9 variant known as ...

3D Protein Modeling Suggests Why COVID-19 Infects Some Animals, but Not Others

Some animals are more susceptible to COVID-19 infection than others, and new research suggests this may be due to distinctive structural features of a protein found on the surface of animal ...

What Makes Certain Groups More Vulnerable to COVID-19?

What makes the elderly and people with underlying conditions more vulnerable to COVID-19? According to a new study, clues can be found in the proteins involved in initiating infection, as the virus ...

Development of New Stem Cell Type May Lead to Advances in Regenerative Medicine

A team has derived a new 'intermediate' embryonic stem cell type from multiple species that can contribute to chimeras and create precursors to sperm and eggs in a culture ...

New Compact Model for Gene Regulation in Higher Organisms

Genes can be turned on and off as needed to adapt to environmental changes. But how do the different molecules involved interact with each other? Scientists present a candidate mathematical model for ...

The Helix of Life: New Study Shows How 'Our' RNA Stably Binds to Artificial Nucleic Acids

Xeno nucleic acids are essential for the development of nucleic acid-based drugs. To be effective, they need to be able to stably bind to natural RNA (a cellular single-stranded version of the DNA, ...

Understanding Bacteria's Metabolism Could Improve Biofuel Production

A new study reveals how bacteria control the chemicals produced from consuming 'food.' The insight could lead to organisms that are more efficient at converting plants into ...

Medicine-Carriers Made from Human Cells Can Cure Lung Infections

Scientists used human white blood cell membranes to carry two drugs, an antibiotic and an anti-inflammatory, directly to infected lungs in mice. The nano-sized drug delivery method successfully ...

Visualization Reveals How a Protein 'Hunkers Down' to Conserve Energy

A visualization made from nearly 100,000 electron microscope images has revealed the ingenious way a protein involved in muscle activity shuts itself down to conserve energy. The protein is called ...

Plant-Inspired Alkaloids Protect Rice, Kiwi and Citrus from Harmful Bacteria

Plants get bacterial infections, just as humans do. When food crops and trees are infected, their yield and quality can suffer. Although some compounds have been developed to protect plants, few of ...

Molecular 'Barcode' Helps Decide Which Sperm Will Reach an Egg
