Random number generators go public

29-Jun-2018 | Sophia Chen, Science , 2018

On 10 July, researchers in Chile will unveil an online public random number service. Later in July, the U.S. National Institute of Standards and Technology (NIST) will launch its Randomness Beacon as a permanent service, upgrading a pilot program that began in 2013. Brazil, too, is planning a ...

When the cure kills—CBD limits biodiversity research

29-Jun-2018 | K. Divakaran Prathapan; Rohan Pethiyagoda; Kamaljit S. Bawa; Peter H. Raven; Priyadarsanan Dharma Rajan; 172 co-sign ..., Science , 2018

The Convention on Biological Diversity (CBD) commits its 196 nation parties to conserve biological diversity, use its components sustainably, and share fairly and equitably the benefits from the utilization of genetic resources. The last of these objectives was further codified in the ...

See-through solar cells could power offices

29-Jun-2018 | Robert F. Service, Science , 2018

Solar windows turn some of the light shining through into electricity. They've been on the market for years. But many of these windows absorb some visible light, leaving them with a reddish or brownish hue, a trait frowned on by architects. Now, new versions are on the way that absorb invisible ...

The power of many

29-Jun-2018 | Elizabeth Pennisi, Science , 2018

Three billion years ago, more or less, life crossed a threshold and began moving toward a multicellular existence. Evidence from multiple directions is showing how this hard-to-fathom leap might have been less difficult than once believed. The evolutionary histories of some groups of organisms ...

Behavior with movement

29-Jun-2018 | Caroline Ash; Gemma Alderton, Science , 2018

Neuroscience The neuronal circuits required for movement reside in the spinal cord. But how does the nervous system coordinate multiple neuronal populations across different brain regions to fulfill an organism's behavioral needs? In a Perspective, Arber and Costa explore the organizational logic ...

Agricultural advances draw opposition that blunts innovation

29-Jun-2018 | Anne Q. Hoy, Science , 2018

Evidence-free challenges increase public misconceptions and feed the world of “parallel science”

Heterogeneous to homogeneous melting transition visualized with ultrafast electron diffraction

29-Jun-2018 | M. Z. Mo; Z. Chen; R. K. Li; M. Dunning; B. B. L. Witte; J. K. Baldwin; L. B. Fletcher; J. B. Kim; A. Ng; R. Redmer; ..., Science , 2018

The ultrafast laser excitation of matters leads to nonequilibrium states with complex solid-liquid phase-transition dynamics. We used electron diffraction at mega–electron volt energies to visualize the ultrafast melting of gold on the atomic scale length. For energy densities approaching the ...

More friction for polyelectrolyte brushes

29-Jun-2018 | Matthias Ballauff, Science , 2018

Skeletal joints must provide lubrication under considerable load. Lubrication between two sliding surfaces in aqueous environments can be greatly enhanced by polyelectrolyte brushes ( 1 ): Long macromolecular chains that bear charges at each repeating unit are grafted densely to a planar or ...

Postimpact earliest Paleogene warming shown by fish debris oxygen isotopes (El Kef, Tunisia)

29-Jun-2018 | K. G. MacLeod; P. C. Quinton; J. Sepúlveda; M. H. Negra, Science , 2018

Greenhouse warming is a predicted consequence of the Chicxulub impact, but supporting data are sparse. This shortcoming compromises understanding of the impact’s effects, and it has persisted due to an absence of sections that both contain suitable material for traditional carbonate- or ...

Warming after the big one

29-Jun-2018 | Caroline Ash; H. Jesse Smith, Science , 2018

Climate Change The Chicxulub impact 65 million years ago, which caused the mass extinction at the Cretaceous-Paleogene boundary, also initiated a long period of strong global warming. Using data from phosphatic microfossils, including fish teeth, scales, and bone, MacLeod et al. estimated global
