Liquid: a liquid filter
Water filtration for human consumption and industrial wastewater purification accounts for huge electricity consumption and CO2 emissions. Passing water through a porous membrane to filter out particles larger than water molecules is a common water processing method. A problem with this filtration method is that membranes are susceptible to fouling (clogging by the filtrates). To…
Truly recycling plastic with reversible polymer chemistry
In the ideal world, recycling plastics should break the polymers back to monomers, its original building blocks. Monomers could then be made into new plastics over and over. The team from the Lawrence Berkeley National Laboratory in California brought us one step closer to the dream of closed-loop, zero-waste plastics. Researchers utilised a family of…
How the search on your window monitors global biodiversity outside the window
Sitting in your room, typing wikipedia.org/wiki/…/, you are actually helping scientists to monitor species outside the window. Recently in the open-access journal PLOS Biology, the University of Oxford, the University of Birmingham and Ben-Gurion University of the Negev collectively published their investigation on how Wikipedia pageview records correlates to seasonal patterns in nature. We had…

Sufferers are vulnerable to involuntary memories of traumatic events, colloquially called “flashbacks”, which are a distressing symptom of the condition. A recent…
Pore over this: Advances in DNA sequencing
Ten years ago, the completion of the Human Genome Project was a milestone in the history of science. The race to be the first team to decode an entire human genome ultimately ended with the two largest groups collaborating and announcing the success of the project in 2001. This was not only a scientific achievement,…

Yeast on the brain: could fungi be linked to Alzheimer’s Disease?
A fungus that can infect the brain may be the key to understanding Alzheimer’s disease. The blood brain barrier (BBB) is a highly selective barrier that allows very few unwanted substances pass through it. However, there are some bacteria and fungi that have found a way to cross the BBB and cause infections; Candida albicans…
CRISPR’s Consequences: An Ethical Tongue Twister
By Abigail Pavey The power to create, destroy or modify life has always been a source of great debate between scientists and among society as a whole. But what happens when scientists decide to go undercover and do what they please? In November 2018, Chinese researcher He Jiankui announced to the world that he had…
