Nano-sponges on graphene make efficient filters of industrial wastewater
August 05, 2022Engineers at the University of Vienna have developed a new composite material that makes an efficient filter for removing organic pollutants from water. The system uses super-porous “nano-sponges” embedded on a sheet of graphene. -
Material obtained from shrimp shells makes for stronger cement
August 02, 2022The production of cement is a major source of carbon emissions, so the less of it that's used, the better. A new study could help, as it shows that cement can be made much stronger with the addition of material derived from waste shrimp shells. -
Polymer bricks made of industrial waste bond together without mortar
August 01, 2022Construction is one of the largest sources of greenhouse gas emissions. Flinders University researchers have now developed a polymer made out of industrial waste that can be formed into building bricks that bond together without needing any mortar.

Scientists restore vital cellular functions to pigs one hour after death
August 03, 2022Scientists have demonstrated a new system that can restore crucial molecular and cellular functions in pigs one hour after death. The experiments could help widen the organ transplantation pool and may even lead to new treatments for heart attacks. -
Synthetic embryos grown from stem cells don't need sperm or eggs
August 02, 2022Researchers have created some of the most advanced synthetic mouse embryos out of stem cells, removing the need for sperm, eggs and even a womb. The technology could help us understand development and eventually be used to grow organs for transplant. -
Newly discovered chemical reactions could explain the origin of life
July 29, 2022Exactly how non-living molecules sparked life is one of the most puzzling mysteries of science. Scientists have now discovered chemical reactions that can produce the building blocks of life out of materials common in early Earth's primordial soup.
