  • Icy giant planets in the laboratory

    25.03.2019

    Giant planets like Neptune may contain much less free hydrogen than previously assumed. Researchers drove shock waves through two different types of plastic to reach the same temperatures and pressures present inside such planets, and observed the behavior using ultra-strong X-ray laser pulses. Unexpectedly, one of these plastics kept its crystalline structure even at the most extreme pressures. Since the icy giant interiors are made up of the same components as the plastic, planetary models may need to be partially reconsidered.

  • Scientist constructs artificial photosynthetic cells

    25.03.2019

    Scientists build artificial cells as models of primitive cells. Research team have constructed artificial cells using minimal components that are able to supply energy to drive gene expression inside a microcompartment, thus these artificial cells can produce energy that helps synthesize parts of the cells themselves. This work marks an important milestone in constructing artificial autotrophic cells, and may shed light on how primordial cells used sunlight as an energy source early in life's history.

  • Bacterial survival strategy

    07.02.2017, EurekAlert!

    Scientists have discovered a long-term epigenetic memory switch that controls different modes of bacterial virulence, a bacterial survival strategy for outsmarting the human immune response. The study sheds new light on bacterial virulence strategies, resulting in increased disease severity, higher infection persistence, and improved host-to-host spreading.

  • Little-known quake, tsunami hazards lurk offshore of Souther

    29.05.2015, ScienceDaily

    While their attention may be inland on the San Andreas Fault, residents of coastal Southern California could be surprised by very large earthquakes -- and even tsunamis -- from several major faults that lie offshore, a new study finds.

  • Offshore islands amplify, rather than dissipate, a tsunami's power

    07.11.2014, Science Daily

    A long-held belief that offshore islands protect the mainland from tsunamis turns out to be the exact opposite of the truth, according to a new study.

  • Scientists examine mysterious tar mounds in the West African deep ocean

    07.11.2014, Science Daily

    More than two thousand mounds of asphalt harboring a wealth of deep-water creatures have been discovered up to two kilometers deep, off the coast of Angola. Scientists have been examining the images and data captured at the site to build an intriguing picture of the life and geology of this underwater area. The naturally-occurring asphalt mounds are made up of the same substance that covers our roads.

  • Understanding the 1989 Loma Prieta earthquake in an urban context

    07.11.2014, Science Daily

    In an urban environment, the effect of a major earthquake such as the 17 Oct. 1989 Loma Prieta event can be pieced together by the infrastructure damaged or destroyed. This study details the effects of the Loma Prieta earthquake still detectable 25 years on and sheds light on the potential damage to infrastructure from future earthquakes along the San Andreas fault or the neighboring Foothills thrust belt.

  • Ancient rhino-relatives were water-loving

    08.10.2014, Science Daily

    The discovery of new bones from a large land mammal that lived about 48 million years ago has led scientists to identify a new branch of mammals closely related to modern horses, rhinos, and tapirs.
