Traditional Ghanaian medicines show promise against tropical diseases

The discovery of new drugs is vital to achieving the eradication of neglected tropical diseases (NTDs) in Africa and around the world. Now, researchers have identified traditional Ghanaian medicines which work in the lab against schistosomiasis, onchocerciasis and lymphatic filariasis, three diseases endemic to Ghana.

Stretching diamond for next-generation microelectronics

Diamond is the hardest material in nature. It also has great potential as an excellent electronic material. A research team has demonstrated for the first time the large, uniform tensile elastic straining of microfabricated diamond arrays through the nanomechanical approach. Their findings have shown the potential of strained diamonds as prime candidates for advanced functional devices in...

Spontaneous robot dances highlight a new kind of order in active matter

Researchers have proposed a new principle by which active matter systems can spontaneously order, without need for higher level instructions or even programmed interaction among the agents. And they have demonstrated this principle in a variety of systems, including groups of periodically shape-changing robots called 'smarticles.'

Land subsidence 'will affect almost fifth of global population'

Unesco warns of urban centres sinking because of unsustainable farming and groundwater extraction Subsidence, or the gradual sinking of land, could affect 19% of the world’s population by 2040, according to new research funded by Unesco.If no action is taken, human activity, combined with drought and rising sea levels exacerbated by global heating, could put many of the world’s coastal cities...

Stretching diamond for next-generation microelectronics

Diamond is the hardest material in nature. But out of many expectations, it also has great potential as an excellent electronic material. A joint research team led by City University of Hong Kong (CityU) has demonstrated for the first time the large, uniform tensile elastic straining of microfabricated diamond arrays through the nanomechanical approach. Their findings have shown the potential of...

The Guardian view on Covid science: cooperation, not just competition | Editorial

Scientists should follow the example of the Chinese professor whose selfless decision to share his breakthrough led to the medical miracle of a vaccineThere are many people deserving of praise for selfless acts during the past 12 months. But one person whose act of scientific generosity ought to be remembered is Zhang Yongzhen. The scientist, who works out of the Shanghai Public Health Clinical...
