Novel electrocatalyst outperforms platinum in alkaline hydrogen production

A novel ruthenium-based catalyst has shown markedly better performance than commercial platinum catalysts in alkaline water electrolysis for hydrogen production. The catalyst is a nanostructured composite material composed of carbon nanowires with ruthenium atoms bonded to nitrogen and carbon to form active sites within the carbon matrix.

Climate change may make species infertile: Study

Certain groups are thought to be most vulnerable to climate-induced fertility loss, including cold-blooded animals and aquatic species. Currently, researchers are trying to predict where species will be lost due to climate change, so they can build suitable reserves in the locations they will eventually need to move to.

Four-year-old tiger found dead in MP's Kanha Reserve

He said no suspicious activities were noticed in the vicinity which could have led one to believe that the death was untoward. The MP government's Public Relations Department official added that the animal's neck bore nail marks, the carcass was partially eaten and drag marks were also found at the spot.

Jiggly Jell-O to make powerful new hydrogen fuel catalyst

A cheap and effective new catalyst can generate hydrogen fuel from water just as efficiently as platinum, currently the best -- but also most expensive -- water-splitting catalyst out there.The catalyst, which is composed of nanometer-thin sheets of metal carbide, is manufactured using a self-assembly process that relies on a surprising ingredient: gelatin, the material that gives Jell-O its jiggle.

UN climate panel says 'unprecedented changes' needed to limit global warming to 1.5°C

Limiting global warming to 1.5°C will require "far-reaching and unprecedented changes," such as ditching coal for electricity to slash carbon emissions, the Intergovernmental Panel on Climate Change (IPCC) has said, launching a special report that said the world must move faster on climate change.

A switch to turn fragrances on and off

Scientists have discovered the switch in plants that turns off production of terpenoids -- carbon-rich compounds that play roles in plant physiology and are used by humans in everything from fragrances and flavorings to biofuels and pharmaceuticals.
