The green anole lizard (Anolis carolinensis), when caught by a predator, can lose its tail and then grow it back.
By understanding the secret of how lizards regenerate their tails, researchers may be able to develop ways to stimulate the regeneration of limbs in humans. Now, a team of researchers from Arizona State University is one step closer to solving that mystery. The scientists have discovered the genetic "recipe" for lizard tail regeneration, which may come down to using genetic ingredients in just the right mixture and amounts.

Multiple fires are visible in in this image of the Para and Mato Grosso states of Brazil.
Multiple fires are visible in in this image of the Para and Mato Grosso states of Brazil. Many of these were most likely intentionally set in order to deforest the land. Deforestation is the removal of a forest or stand of trees where the land is thereafter converted to a nonforest use. Examples of deforestation include conversion of forestland to farms, ranches, or urban use. The herringbone-patterned tan lines cutting through the dark green of the Amazon Rainforest in the middle of the image are evidence of deforestation in the Brazilian state of Pará. The deforestation in Pará follows the Brazialian national motorway BR 163, passing by cities such as Novo Progresso. The lower half of the image shows the state of Mato Grosso.

Daylight was breaking over the central Pacific and coffee brewing aboard the MY Hanse Explorer. Between sips, about a dozen scientists strategized for the day ahead. Some would don wetsuits and slip below the surface to collect water samples around the southern Line Islands' numerous coral reefs. Others would tinker with the whirring gizmos and delicate machinery strewn throughout the 158-foot research vessel. All shared a single goal: Be the first research group to bring a DNA sequencer out into the field to do remote sequencing in real time. Against an ocean of odds, they succeeded.

The Ebola outbreak in West Africa has brought a lot of attention to the deadly virus. According to the World Health Organization, up to 90% of those infected with Ebola die from the virus. Now, researchers publishing August 13 in the Cell Press journal Cell Host & Microbe reveal how Ebola blocks and disables the body's natural immune response. Understanding how Ebola disarms immune defenses will be crucial in the development of new treatments for the disease.

Few animals can boast of being as tough as the Antarctic midge. Its larvae develop over not one but two Antarctic winters, losing nearly half their body mass each time. It endures high winds, salt, and intense ultraviolet radiation. As an adult, the midge gets by without wings and lives for only a week or so before starting its life cycle all over again.

Researchers with The Cancer Genome Atlas (TCGA) Research Network have completed the largest, most diverse tumor genetic analysis ever conducted, revealing a new approach to classifying cancers. The work, led by researchers at the UNC Lineberger Comprehensive Cancer Center at the University of North Carolina at Chapel Hill and other TCGA sites, not only revamps traditional ideas of how cancers are diagnosed and treated, but could also have a profound impact on the future landscape of drug development.

Spider silk is an impressive material; lightweight and stretchy yet stronger than steel. But the challenge that spiders face to produce this substance is even more formidable. Silk proteins, called spidroins, must convert from a soluble form to solid fibers at ambient temperatures, with water as a solvent, and at high speed. How do spiders achieve this astounding feat? In new research publishing in the open access journal PLOS Biology on August 5, Anna Rising and Jan Johansson show how the silk formation process is regulated. The work was done at the Swedish University of Agricultural Sciences (SLU) and Karolinska Institutet in collaboration with colleagues in Latvia, China and USA.
