Adding small amounts of seaweed to contaminated soil could prove to be a natural and effective way of breaking down the toxic pesticide DDT, according to new research in the Journal of Chemical Technology and Biotechnology. A British biologist, Ian Singleton, worked with colleagues in Australia and Thailand to find the right formula to use. Too much seaweed hindered biodegradation, but the most effective mix – 0.5% seaweed added to waterlogged soil – managed to remove 80% of the DDT present over six weeks, lowering the levels of DDT enough to pass Australian Environment Protection Authority criteria.
Why it is necessary
Although DDT is banned in most of the industrial world, it is one of the most effective anti-mosquito agents available. Twenty five countries, including South Africa, still use it in the fight against malaria, despite strong opposition from environmental groups. If DDT could be more quickly broken down after use, the overall health benefits to countries with big malaria problems could be enormous.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
