Gradual decline of dinosaurs before extinction

Statistical analysis suggests that the mass extinction of dinosaurs thought to have been triggered by an asteroid impact was preceded by the animals' gradual but inexorable decline over at least 40 million years, according to a study.

Study examines safety, immune response of candidate Ebola vaccines

In a study appearing in the April 19 issue of JAMA, Matthew D. Snape, F.R.C.P.C.H., M.D., of the University of Oxford, United Kingdom, and colleagues conducted a phase 1 trial to evaluate the tolerability and immunogenicity of two candidate Ebola vaccines, an adenovirus type 26 vector vaccine (Ad26.ZEBOV), and a modified Ankara vector vaccine (MVA-BN-Filo).

Antimalarial resistance to drug is not passed on to future generations

Parasites that develop resistance to the antimalarial drug atovaquone cannot pass this resistance on to offspring, a new study suggests. Atovaquone is a drug used to treat malaria, a mosquito-borne disease caused by parasites, but the parasites can develop resistance to this drug and there is concern that this resistance will spread, as it has for other antimalarials.

How parasitic worms help minimize inflammatory bowel disease

Intestinal worms beneficially influence the composition of gut microbiota in the presence of inflammatory bowel disease, a new study suggests. The findings provide important insights into how intestinal worms, or helminths, manipulate the gut microbiota in a way that is beneficial for its host.

Severe reduction in thermal tolerance projected for great barrier reef

Corals within Great Barrier Reef (GBR) have developed a thermal tolerance mechanism to adapt to sharp increases in sea surface temperatures, but near-future temperature increases of as little as 0.5°C may result in this protective mechanism being lost, a new study finds.

Progress in probing dynamical responses of heterogeneous materials

Energy transformation and dissipation mechanisms in dynamical responses of heterogeneous materials are far from clear to scientists, which challenges their engineering applications. Researchers in Beijing point out that these complex multi-scale behaviors can be probed via a series of coarse-grained modelings. The similarity parameters, invariants and slow-varying quantities are independent variables in constructing constitutive relations. A set of new schemes are proposed to analyze the complex structures and some hidden underlying mechanisms are revealed.

Facile fabrication of a nanoporous Si/Cu composite and its application as a high-performance anode in lithiumion batteries

Nanoporous (NP) Si/Cu composites with different Cu contents are easily fabricated by means of alloy refining followed by facile electroless dealloying in mild conditions. NP-Si/Cu composites show a three-dimensional porous network nanoarchitecture with conductive Cu network embedded. With the advantages of rich porosity and integration of Cu into a nanoporous Si backbone, the NP-SiCu composites exhibit much higher cycling reversibility than pure NP-Si as an anode material for LIBs.

A facile surfactant-free synthesis of Rh flower-like nanostructures

A facile, surfactant-free synthesis of Rh flowerlike nanostructure was developed by hydrothermal reduction of Rh(acac)3 with formaldehyde. The unique Rh nanoflowers were constructed from ultrathin nanosheets with specific surface area of 79.3 m2g−1, which was much larger than that of commercial Rh black. The Rh nanoflowers exhibited excellent catalytic performance in the catalytic hydrogenation of phenol and cyclohexene, in contrast to the commercial Rh black.

Current methods cannot predict damage to coral reefs

Coral reefs are severely endangered by a warming and increasingly acidic ocean. Although species-level effects have been studied, these pieces of the puzzle have not been assembled into a broader view. Ecosystem-level effects may be more severe than is currently anticipated.
