Quantum biology: Algae evolved to switch quantum coherence on and off
A UNSW Australia-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.
Rare byproduct of marine bacteria kills cancer cells by snipping their DNA
(Phys.org) —Yale University researchers have determined how a scarce molecule produced by marine bacteria can kill cancer cells, paving the way for the development of new, low-dose chemotherapies.
Scientists hope bacterial blueprints will soon give doctors and nurses fewer sleepless nights
One of the most common types of bacterial infection might soon give doctors and nurses fewer sleepless nights, thanks to a discovery made by scientists at Trinity College Dublin. The scientists used X-ray ...
Researchers identify the metabolic products of foulbrood pathogen in honeybees
Infections with American foulbrood can destroy entire bee populations. A team of German and Dutch researchers has now isolated metabolic products of the pathogen that causes it, Paenibacillus larvae. The ...
Implanted biofuel cell converts bug's chemistry into electricity: Scientists take step toward cyborgs
An insect's internal chemicals can be converted to electricity, potentially providing power for sensors, recording devices or to control the bug, a group of researchers at Case Western Reserve University report.

Scientists discover molecular secrets of 2,000-year-old Chinese herbal remedy
For roughly two thousand years, Chinese herbalists have treated Malaria using a root extract, commonly known as Chang Shan, from a type of hydrangea that grows in Tibet and Nepal. More recent studies suggest that halofuginone, ...
Engineering a protein to prevent brain damage from toxic agents
Research at New York University is paving the way for a breakthrough that may prevent brain damage in civilians and military troops exposed to poisonous chemicals—particularly those in pesticides and chemical weapons.
The symphony of life, revealed: New imaging technique captures vibrations of proteins
Like the strings on a violin or the pipes of an organ, the proteins in the human body vibrate in different patterns, scientists have long suspected.
Simulating how the Earth kick-started metabolism
(Phys.org) —Researchers have developed a new approach to simulating the energetic processes that may have led to the emergence of cell metabolism on Earth – a crucial biological function for all living ...
Metabolism may have started in our early oceans before the origin of life
The chemical reactions behind the formation of common metabolites in modern organisms could have formed spontaneously in the earth's early oceans, questioning the events thought to have led to the origin ...
How a Silly Putty ingredient could advance stem cell therapies
The sponginess of the environment where human embryonic stem cells are growing affects the type of specialized cells they eventually become, a University of Michigan study shows.
ACS chemistry mavens stir up hot sauce science
Chemists devise a new way to manufacture peptide drugs, which hold promise for treating many diseases
Small protein fragments, also called peptides, are promising as drugs because they can be designed for very specific functions inside living cells. Insulin and the HIV drug Fuzeon are some of the earliest ...
