What Cold Lizards in Miami Can Tell Us About Climate Change Resilience

When temperatures go below a critical limit, sleeping lizards lose their grip and fall out of trees. But when researchers collected the scaled survivors of a record cold snap, they discovered that a ...

Microbial Diversity Below Seafloor Is as Rich as on Earth's Surface

For the first time, researchers have mapped the biological diversity of marine sediment, one of Earth's largest global biomes. The research team discovered that microbial diversity in the dark, ...

CRISPR Meets Pac-Man: New DNA Cut-and-Paste Tool Enables Bigger Gene Edits

Gene editing for the development of new treatments, and for studying disease as well as normal function in humans and other organisms, may advance more quickly with a new tool for cutting larger ...

Declines in Shellfish Species on Rocky Seashores Match Climate-Driven Changes

Mussels, barnacles, and snails are declining in the Gulf of Maine, according to a new article by biologists. Their 20-year dataset reveals that the ...

Repairing the Photosynthetic Enzyme Rubisco

Researchers have elucidated how Rubisco activase works. As the name indicates, this enzyme is critical for repairing Rubisco once it has lost its ...

CRISPR-Induced Immune Diversification in Host-Virus Populations

Just like humans, microbes have equipped themselves with tools to recognize and defend themselves against viral invaders. In a continual evolutionary battle between virus and host, CRISPR-Cas act as ...

Prebiotic Chemistry: In the Beginning, There Was Sugar

Organic molecules formed the basis for the evolution of life. But how could inorganic precursors have given rise to them? Chemists now reports a reaction pathway in which minerals catalyze the ...

Light Pollution Alters Predator-Prey Interactions Between Cougars and Mule Deer in Western US

A new study provides strong evidence that exposure to light pollution alters predator-prey dynamics between mule deer and cougars across the intermountain West, a rapidly growing region where ...

AI Methods of Analyzing Social Networks Find New Cell Types in Tissue

In situ sequencing enables gene activity inside body tissues to be depicted in microscope images. To facilitate interpretation of the vast quantities of information generated. Researchers have now ...

High Social and Ecological Standards for Chocolate

Worldwide demand for food from the tropics that meets higher environmental and social standards has risen sharply in recent years. Consumers often have to make ethically questionable decisions: ...

Neurons in a Visual Brain Area of Zebrafish Are Arranged as a Map for Catching Prey

Spotting, pursuing and catching prey - for many animals this is an essential task for survival. Scientists now show in zebrafish that the localization of neurons in the midbrain is adapted to a ...

Natural Killer Cells Also Have a Memory Function

Good news for the human immune system: researchers have managed to ascribe an immunological memory function to a subset of cytotoxic NK cells, which have hitherto been regarded as ...

Tapping Secrets of Aussie Spider's Unique Silk

The basket-web spider, which is found only in Australia, has revealed it not only weaves a unique lobster pot web but that its silk has elasticity and a gluing substance, that creates a high degree ...

Losing Flight Had Huge Benefits for Ants

Researchers have taken detailed scans of worker ants to examine the hypothesis that the loss of flight is directly connected to the evolution of ...

Those Funky Cheese Smells Allow Microbes to 'Talk' to and Feed Each Other

Researchers found that bacteria essential to ripening cheese can sense and respond to compounds produced by fungi in the rind and released into the air, enhancing the growth of some species of ...

Thin tissue grafts and flexible electronics have a host of applications for wound healing, regenerative medicine and biosensing. A new device inspired by an octopus's sucker rapidly transfers ...

Fats Fighting Back Against Bacteria

With antibiotic-resistant superbugs on the rise, this research shows a new way that cells are using to protect themselves - using fats as a covert weapon, and giving us new insights into alternative ...

Researchers have identified a number of 'silent' mutations in the roughly 30,000 letters of the COVID-19 virus's genetic code that helped it thrive once it made the leap from bats and ...

Gel Instrumental in 3D Bioprinting Biological Tissues

The eventual creation of replacement biological parts requires fully three-dimensional capabilities that two-dimensional and three-dimensional thin-film bioprinting cannot supply. Now, using a yield ...

During COVID, Scientists Turn to Computers to Understand C4 Photosynthesis

When COVID closed down their lab, a team of researchers turned to computational approaches to understand what makes some plants better adapted to transform light and carbon dioxide into yield through ...

Ingestible Capsule That Could Help Demystify the Gut-Brain Axis

A team of experts from engineering, neuroscience, applied microbiology, and physics has been making headway on building a platform that can monitor and model the real-time processing of gut ...

Supergene Discovery Leads to New Knowledge of Fire Ants

A unique study conducted by entomologists led to the discovery of a distinctive supergene in fire ant colonies that determines whether young queen ants will leave their birth colony to start their ...

Researchers Find Diverse Communities Comprise Bacterial Mats Threatening Coral Reefs

A research team found that cyanobacterial mats threatening the health of coral reefs are more diverse and complex than scientists previously ...

Monkey Study Suggests That They, Like Humans, May Have 'Self-Domesticated'
