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.
Desalination breakthrough could lead to cheaper water filtration
- ScienceDaily

Producing clean water at a lower cost could be on the horizon after researchers solved a complex problem that has baffled scientists for decades, until now.
Stretching diamond for next-generation microelectronics
- ScienceDaily
- 20/12/31 20:15
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
- ScienceDaily
- 20/12/31 20:15
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.'
Multiple mosquito blood meals accelerate malaria transmission
- ScienceDaily
- 20/12/31 20:14
Multiple bouts of blood feeding by mosquitoes shorten the incubation period for malaria parasites and increase malaria transmission potential, according to a new study.
New virtual screening strategy identifies existing drug that inhibits COVID-19 virus
- ScienceDaily
- 20/12/31 20:14
A novel computational drug screening strategy combined with lab experiments suggest that pralatrexate, a chemotherapy medication originally developed to treat lymphoma, could potentially be repurposed to treat COVID-19.
Asian tiger mosquito poses low risk for Zika virus outbreaks

The Asian tiger mosquito does not pose a major risk for Zika virus epidemics, according to a new study.
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...
Controlling the nanoscale structure of membranes is key for clean water, researchers find
A desalination membrane acts as a filter for salty water: push the water through the membrane, get clean water suitable for agriculture, energy production and even drinking. The process seems simple enough, but it contains complex intricacies that have baffled scientists for decades—until now.
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...
