Two of Alaska's most active volcanoes -- Pavlof and Cleveland -- are currently erupting. At the time of this post, their activity continues at low levels, but energetic explosions could occur without warning. Located close to the western end of the Alaska Peninsula, Pavlof is one of the most active volcanoes in the Aleutian arc, having erupted more than 40 times since the late 1700's.

Computer simulations of galaxies growing over billions of years have revealed a likely scenario for how they feed: a cosmic version of swirly straws. The results show that cold gas -- fuel for stars -- spirals into the cores of galaxies along filaments, rapidly making its way to their "guts." Once there, the gas is converted into new stars, and the galaxies bulk up in mass.

For the first time, scientists working at the National Institute of Standards and Technology (NIST) have demonstrated a new type of lens that bends and focuses ultraviolet (UV) light in such an unusual way that it can create ghostly, 3D images of objects that float in free space.

Scientists have developed a novel experimental model that reproduces for the first time this pattern of alpha-synuclein brain spreading and provides important clues on the mechanisms underlying this pathological process. They triggered the production of human alpha-synuclein in the lower rat brain and were able to trace the spreading of this protein toward higher brain regions. The new experimental paradigm could promote the development of ways to halt or slow down disease development in humans.

New research presented today shows that formation of new neurons in the hippocampus -- a brain region known for its importance in learning and remembering -- could cause forgetting of old memories by causing a reorganization of existing brain circuits. Researchers argue this reorganization could have the positive effect of clearing old memories, reducing interference and thereby increasing capacity for new learning.

Approximately a year ago, the journal Science published an article about bexarotene as a potential Alzheimer's drug -- a significant breakthrough and an important starting point for further Alzheimer's research. Now other researchers have tested this candidate drug in various Alzheimer's animal test models. Their results were different, as were those of two American study groups. Therefore, they have recommended that bexarotene should not be tested on patients.

Biological processes are generally based on events at the molecular and cellular level. To understand what happens in the course of infections, diseases or normal bodily functions, scientists would need to examine individual cells and their activity directly in the tissue. The development of new microscopes and fluorescent dyes in recent years has brought this scientific dream tantalizingly close. Scientists from the Max Planck Institute of Neurobiology in Martinsried have now presented two studies introducing new indicator molecules which can visualize the activation of T cells. Their findings provide new insight into the role of these cells in the autoimmune disease multiple sclerosis (MS). The new indicators are set to be an important tool in the study of other immune reactions as well.

From the high-resolution glow of flat screen televisions to light bulbs that last for years, light-emitting diodes (LEDs) continue to transform technology. The celebrated efficiency and versatility of LEDs -- and other solid-state technologies including laser diodes and solar photovoltaics -- make them increasingly popular. Their full potential, however, remains untapped, in part because the semiconductor alloys that make these devices work continue to puzzle scientists. Scientists have now used electron microscopy imaging techniques to settle a solid-state controversy and raise new experimental possibilities.

One proposed measure is the reforestation of the watershed.
