Jaguars robust to climate extremes but lack of food threatens species

Researchers lead a world-first investigation into the chances of wild jaguars surviving climate extremes with six scenarios modelling the behavior, mating, births of cubs, competition, illegal hunting, death from starvation and availability of prey.

The dazzling winners of the British Ecological Society’s photo awards

Images of the extraordinary, but endangered, Dalmatian pelican and weaver ants caring for their young are among those awarded in this year’s British Ecological Society’s “Capturing Ecology” photography competition

‘Going Green’ Risks Destroying The British Car Industry

To my mind, Boris Johnson’s announcement of the ban on the sale of all new petrol and diesel cars from 2030 – just ten years off ­– is one of the most significant political decisions in modern times. It says…

CRISPRi screens reveal sources of metabolic robustness in E. coli

Metabolic robustness, the ability of a metabolic system to buffer changes in its environment, is not always a welcome feature for microbiologists: it interferes with metabolic engineering or prevents that antibiotics kill bacteria. Therefore it is important to understand the mechanisms that enable metabolic robustness. A massively parallel CRISPRi screen demonstrated that E. colimetabolism is very robust against knockdowns of enzymes, and multi-omics data revealed the mechanisms behind it. In the future, the researchers want to apply this knowledge to build better models of metabolism, which enable rational-design of industrial microbes.

The bull Y chromosome has evolved to bully its way into gametes

Scientists present the first ever full, high-resolution sequence of the Y chromosome of a Hereford bull. The research, more than a decade in the making, suggests that bulls’ Y chromosomes have evolved dozens of copies of the same genes in a selfish attempt to make more males — a move that is countered in the female-determining X chromosome.

Abundance of prey species is key to bird diversity in cities

A team of scientists collaborated to analyze breeding bird data gathered by citizen scientists. They found that the abundance of invertebrates such as insects or spiders as prey is a key factor affecting bird diversity in the city. The more prey is available, the more diverse the urban bird communities are.

Purdue-led team named quarterfinalist in DOE solar innovation contest

(Purdue University) A Purdue University innovator and his team are among the quarterfinalists in a national solar desalination innovation contest. They received the recognition for a technology to use solar power to purify high salinity water, such as treating desalination brine or produced water from oil and gas extraction.
