Along the shores of Africa’s Lake Victoria in Kenya roughly 2.9 million years ago, early human ancestors used some of the oldest stone tools ever found to butcher hippos and pound plant material, according to new research.

A research team from the Otto Diels Institute of Organic Chemistry at Kiel University has developed a special palladium catalyst that can for the first time selectively activate carbon-hydrogen bonds.

A new modelling study shows that the Seychelles and other islands in the western Indian Ocean are not responsible for most of the plastic waste that accumulates on their beaches. Indonesia, India, and Sri Lanka were found to be the main sources of land-based plastic debris.

Scientists have decoded the physical process that takes place in the mouth when a piece of chocolate is eaten, as it changes from a solid into a smooth emulsion that many people find totally irresistible.

A study from DePaul University researcher Noé de la Sancha models new dimensions of biodiversity among small mammal populations, as a function of how far they dwell from the forest’s edge. The research is published in the journal Diversity and Distributions.

If we can slow down the pace of the aging process, more elderly people will be able to stay healthy. More people may then enjoy good health in their old age than what is the case today. A new study shows that it may be possible to achieve just that.

Researchers have revealed numerous new findings about chocolate including the possibility of strengthening teeth, the compounds required to make it tasty and how can one know if a chocolate bar is authentic.

Existing ways of calculating biodiversity dynamics are not very effective in detecting wholesale species community change due to the effects of ocean acidification. University of Adelaide research shows that in cases where biodiversity metrics show no change or little change, there may still be reorganisation of ecological communities in our oceans.

Nanoengineers at the University of California San Diego have developed microscopic robots, called microrobots, that can swim around in the lungs, deliver medication and be used to clear up life-threatening cases of bacterial pneumonia.

Size distribution, shape factor, bulk density —  there are numerous parameters that describe a bulk material as a whole. But their determination is also subject to many sources of error. These six tips for particle analysis show how to ensure that you end up with meaningful results when characterizing powders.
