Experts highlight ebola vaccine progress and suggest next steps

Despite promising advances, important scientific questions remain unanswered in the effort to develop a safe and effective Ebola vaccine, according to members of an international Ebola research consortium. The experts now review the current field of Ebola vaccine candidates and clinical trials and highlight key gaps in knowledge that need to be addressed by future research.

Deep in the weeds: Using eDNA sequencing to survey pondweed diversity

Researchers have developed a protocol using environmental DNA (eDNA) to identify aquatic plant diversity, making ecological biodiversity surveys of these plant communities faster and less expensive. Their study on pondweeds -- an important bioindicator of aquatic ecosystem health -- allows researchers to overcome difficulties in monitoring and identification, and draw conclusions regarding plant diversity and water quality. eDNA is a rapidly emerging technique, but its use in aquatic habitats has been understudied.

Rescuing antibiotics’ effectiveness in face of drug-resistant bacteria

Bacteria -- especially Gram-negative strains -- are becoming increasingly resistant to current antibiotic drugs, and the development of new classes of antibiotics has slowed. Faced with these challenges, investigators are studying the potential of combination therapy, in which two or more drugs are used together to increase or restore the efficacy of both drugs against a resistant bacterial pathogen. Now new research indicates that such synergy may work even when bacteria become resistant to colistin, which is considered a treatment agent of last resort.

Tough life in the savannah? Chimpanzee foods are mechanically more demanding than previously thought

A study has analyzed the mechanical properties and the isotopic composition of plant foods eaten by chimpanzees living in the tropical rain forest and savannah woodland. They found that the savannah chimpanzees eat foods that are more mechanically challenging and therefore may place higher selective pressures on their chewing apparatus compared to their conspecifics living in the rainforest.

Fresh insight into invasive plant that blights UK rivers

New research into the behavior of an invasive plant seen on riverbanks across the UK could help improve the management of the problem, experts have found.

Researcher reveal insights into brain circuitry

New research reveals novel molecular insights into how multiple cell types drive the formation and maturation of brain circuits.

New water simulation captures small details even in large scenes

When designers select a method for simulating water and waves, they have to choose either fast computation or realistic effects; state-of-the-art methods are only able to optimize one or the other. Now, a new method bridges this gap. Their simulation method can reproduce complex interactions with the environment and tiny details over huge areas--all in real time.

New details in how sense of smell develops

Researchers have uncovered new details in how the olfactory epithelium develops. The new knowledge could help scientists prove that turbinates and the resulting larger surface area of the olfactory epithelium are one definitive reason dogs smell so well.

Does rain follow the plow?

There are many factors that play a role in whether or not it rains, and new research shows that human activity may be one of them.

Laziness helped lead to extinction of Homo erectus

New archaeological research has found that Homo erectus, an extinct species of primitive humans, went extinct in part because they were 'lazy'.
