Bioengineers close to brewing opioid painkillers without using opium from poppies
For centuries poppy plants have been grown to provide opium, the compound from which morphine and other important medicines such as oxycodone are derived.
Water's reaction with metal oxides opens doors for researchers
A multi-institutional team has resolved a long-unanswered question about how two of the world's most common substances interact.
A breath reveals a hidden image in anti-counterfeit drug labels
An outline of Marilyn Monroe's iconic face appeared on the clear, plastic film when a researcher fogs it with her breath.
New tools advance bio-logic: Researchers build more sophisticated synthetic gene circuits
(Phys.org) —Researchers at Rice University and the University of Kansas Medical Center are making genetic circuits that can perform more complex tasks by swapping protein building blocks.
Characterizing strontium ruthenate crystals for electrochemical applications
(Phys.org) —Summer's heat and humidity bring us to the controls for the air conditioning unit long before we receive a government alert to monitor our use of electricity. While we may lower the thermostat ...
Going to extremes for enzymes
In the age-old nature versus nurture debate, Douglas Clark, a faculty scientist with Berkeley Lab and the University of California (UC) Berkeley, is not taking sides. In the search for enzymes that can break ...
Researchers identify a pheromone in the urine of male tilapia fish that stimulates spawning in females
The exchange of chemical signals between organisms is considered the oldest form of communication. Acting as messenger molecules, pheromones regulate social interactions between conspecifics, for example, ...
Synthesis produces new antibiotic: Scientists confirm potent synthesis of natural tetracycline
A fortuitous collaboration at Rice University has led to the total synthesis of a recently discovered natural antibiotic.
Scientists learn to control reactions with the shape of a rare-earth catalyst
(Phys.org) —Scientists at the Department of Energy's Oak Ridge National Laboratory have discovered they can control chemical reactions in a new way by creating different shapes of cerium oxide, a rare-earth-based ...
Physics research removes outcome unpredictability of ultracold atomic reactions
Findings from a physics study by a Kansas State University researcher are helping scientists accurately predict the once unpredictable.
Catalytic gold nanoclusters promise rich chemical yields
(Phys.org) —Old thinking was that gold, while good for jewelry, was not of much use for chemists because it is relatively nonreactive. That changed a decade ago when scientists hit a rich vein of discoveries ...
Zombie ant fungi 'know' brains of their hosts
(Phys.org) —A parasitic fungus that reproduces by manipulating the behavior of ants emits a cocktail of behavior-controlling chemicals when encountering the brain of its natural target host, but not when ...
Marine protected areas might not be enough to help overfished reefs recover
Pacific corals and fish can both smell a bad neighborhood, and use that ability to avoid settling in damaged reefs.
New tool identifies therapeutic proteins in a 'snap'
(Phys.org) —In human and bacterial cells, glycosylation – the chemical process of attaching complex sugar molecules to proteins – is as fundamental as it gets, affecting every biological mechanism from cell signaling ...
