A drug created from a malaria protein stopped tumour growth of chemotherapy-resistant bladder cancer, offering hope for cancer patients not responding to standard treatments.

Scientists have found that a caterpillar commercially bred for fishing bait has the ability to biodegrade polyethylene: one of the toughest and most used plastics, frequently found clogging up landfill sites in the form of plastic shopping bags.

Ocean warming since the 1980s is linked to the spread of toxic algae, according to a newly published study led by Dr. Christopher Gobler, marine science professor in the School of Marine and Atmospheric Sciences (SoMAS) at Stony Brook University.

Brown University researchers have developed a new composite catalyst that can perform four separate chemical reactions in sequential order and in one container to produce compounds useful in making a wide range of pharmaceutical products.

Plastic, rubber, and many other useful materials are made of polymers — long chains arranged in a cross-linked network. At the molecular level, these polymer networks contain structural flaws that weaken them.

Several years ago, MIT researchers were the first to measure certain types of these defects, called “loops,” which are caused when a chain in the polymer network binds to itself instead of another chain. Now, the same researchers have found a simple way to reduce the number of loops in a polymer network and thus strengthen materials made from polymers.
