Heat-stressed fish embryos can induce stress in nearby embryos
Heat-stressed fish embryos release chemical signals that change the appearance, behavior, and development of fish embryos that were not heat stressed, according to a study. Stress during development can change how an embryo grows and which genes are.....»»
Engineers create bacteria that can synthesize an unnatural amino acid
In a study recently published in Nature Chemical Biology, researchers focused on para-nitro-L-phenylalanine (pN-Phe), a non-standard amino acid that is neither one of the twenty standard amino acids nor observed in nature. pN-Phe has been used by oth.....»»
Estonian researchers investigate using local herbs to fight Lyme disease
Approximately one in three ticks in Estonia and up to one in four in Tallinn carry bacteria that cause borreliosis. Scientists of TalTech are investigating whether medicinal plants growing in Estonia could be used to fight Lyme disease and destroy th.....»»
Where have all the Luddites gone? Exploring what makes us human—and whether modern technology threatens to destroy it
The great—if sometimes overlooked—20th-century philosopher and cultural critic Günther Anders once proposed that our modern age is characterized by a dangerous and pervasive "Apocalypse-Blindheit": a blindness to the apocalypse......»»
Vinegar could be secret ingredient in fight against climate crisis
Chemical engineers at Monash University have developed an industrial process to produce acetic acid that uses the excess carbon dioxide (CO2) in the atmosphere and has a potential to create negative carbon emissions......»»
Using microbial degradation to break down chlorinated PFAS in wastewater
A team of chemical and environmental engineers at the University of California, Riverside, has found a way to use microbial degradation to break down chlorinated PFAS in wastewater. In their paper published in the journal Nature Water, the group desc.....»»
