How cell nuclei squeeze into tight spaces
As cells move throughout our bodies, they often have to squeeze through tight nooks and crannies in their environment, reliably springing back to their original shape. The structures involved in this process are still a mystery, but now a research team reports one protein responsible for giving a cell's nucleus its durable, deformable nature. These results, the authors say, may explain the invasiveness of certain cancer cells.

Monkeys protect against lethal Ebola Sudan infection four days after infection
Researchers have protected nonhuman primates against Ebola Sudan four days following exposure to the virus.

Transcription factor Foxn1 and preserving immune function in later life
Researchers use new experimental models and analytical tools to investigate genes regulated by Foxn1, becoming the first to identify the DNA sequence bound by the transcription factor. Among the hundreds of genes whose expression is regulated by Foxn1 are genes essential to attract precursor cells in the blood to the thymus, that commit precursor cells to become T cells, and that provide the molecular machinery which allows T cell selection to best serve an individual.

Single-celled fungi multiply, alien-like, by fusing cells in host
Biologists report that microsporidia fuse the cells of their animal hosts together so they can multiply and quickly spread, alien-like, within their hosts' uninfected cells.

Sick animals limit disease transmission by isolating themselves from their peers
Sick wild house mice spend time away from their social groups, leading to a decrease in their potential for disease transmission according to a new study. The results can improve models focused on predicting the spread of infectious diseases like influenza or Ebola in humans.

Canine hereditary disorders are more widespread than previously indicated
New research brings new information about genetic disorders causing diseases in different dog breeds. The results can be utilized both in dog breeding and veterinary diagnostics.

Citrus fruits could help prevent obesity-related heart disease, liver disease, diabetes
Oranges and other citrus fruits are good for you -- they contain plenty of vitamins and substances, such as antioxidants, that can help keep you healthy. Now a group of researchers reports that these fruits also help prevent harmful effects of obesity in mice fed a Western-style, high-fat diet.

Edible food packaging made from milk proteins
Most foods at the grocery store come wrapped in plastic packaging. Not only does this create a lot of non-recyclable, non-biodegradable waste, but thin plastic films are not great at preventing spoilage. Scientists are now developing a packaging film made of milk proteins that addresses these issues -- and it is even edible.

Squid, jellyfish and wrinkled skin inspire materials for anti-glare screens and encryption
What do squid and jellyfish skin have in common with human skin? All three have inspired a team of chemists to create materials that change color or texture in response to variations in their surroundings. These materials could be used for encrypting secret messages, creating anti-glare surfaces, or detecting moisture or damage.
