Arctic melt ponds form when meltwater clogs ice pores

A team of researchers, including a mathematician, has determined how Arctic melt ponds form, solving a paradoxical mystery of how a pool of water actually sits atop highly porous ice.

Facts, beliefs, and identity: The seeds of science skepticism

From climate skeptics to anti-vaxxers, psychologists are studying what motivates and drives our decisions to pay attention to some facts while ignoring others.

Seoul virus outbreak associated with home-based rat-breeding facilities

Experts from CDC are working with the Illinois Department of Health and the Wisconsin Department of Health Services to investigate cases of Seoul virus infections among eight people who worked at several rat-breeding facilities in the two states. Seoul virus is not commonly found in the United States, though there have been several reported outbreaks in wild rats. This is the first known outbreak associated with pet rats in the United States.

Study of round worm that returns to life after freezing

The first molecular study of an organism able to survive intracellular freezing (freezing within its cells) is published in a new paper that represents a milestone in scientists’ understanding of an extraordinary adaptation.

New genetic engineering technique could help design, study biological systems

A new technique will help biologists tinker with genes, whether the goal is to turn cells into tiny factories churning out medicines, modify crops to grow with limited water or study the effects of a gene on human health. The technique allows scientists to precisely regulate how much protein is produced from a particular gene. The process is simple yet innovative and, so far, works in everything from bacteria to plants to human cells.

We all need contacts: How organelles hug in cells

Scientists have made a breakthrough in understanding how different compartments (or organelles) of human cells interact.

Team uncovers cellular responses to bird flu vaccine

New research eavesdrops on gene expression in human immune system cells before and after vaccination against bird flu, exposing cellular responses associated with a vaccine constituent called AS03, short for adjuvant system 03. Using massive computation, the investigators pursue a systems biology approach, providing a new wealth of detail about vaccine responses and data for the generation of new hypotheses.

How bacteria exploit a chink in the body’s armor

Scientists have discovered how a unique bacterial enzyme can blunt the body's key weapons in its fight against infection.

New findings on how plants manage immune response

New research has uncovered a previously unknown means by which plants are able to regulate how their immune systems respond to pathogens.

Seeking structure with metagenome sequences

Scientists now report that structural models have been generated for 12 percent of the protein families that had previously had no structural information available.
