The soil bacteria Streptomyces form filamentous branches that extend into the air to create spiraling towers of spores.
Scientists have identified the developmental on-off switch for Streptomyces, a group of soil microbes that produce more than two-thirds of the world's naturally derived antibiotic medicines.

A candidate Ebola vaccine could be given to healthy volunteers in the UK, The Gambia and Mali as early as September, as part of an series of safety trials of potential vaccines aimed at preventing the disease that has killed more than 1,400 people in the current outbreak in West Africa.

In response to an ongoing, unprecedented outbreak of Ebola virus disease (EVD) in West Africa, a team of researchers from the Broad Institute and Harvard University, in collaboration with the Sierra Leone Ministry of Health and Sanitation and researchers across institutions and continents, has rapidly sequenced and analyzed more than 99 Ebola virus genomes. Their findings could have important implications for rapid field diagnostic tests. The team reports its results online in the journal Science.

About 400 million years ago a group of fish began exploring land and evolved into tetrapods – today's amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and fins in a terrestrial environment and what evolutionary processes were at play remain scientific mysteries.

Treating the rare disease MPS I is a challenge. MPS I, caused by the deficiency of a key enzyme called IDUA, eventually leads to the abnormal accumulation of certain molecules and cell death.

New findings show a surprisingly high level of genetic diversity in honeybees, and indicate that the species most probably originates from Asia, and not from Africa as previously thought.
In a study published in Nature Genetics, researchers from Uppsala University present the first global analysis of genome variation in honeybees. The findings show a surprisingly high level of genetic diversity in honeybees, and indicate that the species most probably originates from Asia, and not from Africa as previously thought.

A dead ant manipulated by a species of so-called "zombie ant fungus " clings to a twig in a South Carolina forest.
A parasitic fungus that reproduces by manipulating the behavior of ants emits a cocktail of behavior-controlling chemicals when encountering the brain of its natural target host, but not when infecting other ant species, a new study shows.

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.

Handwashing with antibacterial soap exposes hospital workers to significant and potentially unsafe levels of triclosan, a widely-used chemical currently under review by the U.S. Food and Drug Administration, according to a study led by researchers from UC San Francisco.

The arapaima fish, which once dominated Amazon fisheries, is long and can weigh as much as 400 pounds.
An international team of scientists has discovered that a large, commercially important fish from the Amazon Basin has become extinct in some local fishing communities.
