Breakthrough in race to create 'bio-batteries'
(Phys.org) —Scientists at the University of East Anglia have made an important breakthrough in the quest to generate clean electricity from bacteria.
Transistor made from vanadium dioxide could function as smart window for blocking infrared light
The transistor is the ultimate on-off switch. When a voltage is applied to the surface of a semiconductor, current flows; when the voltage is reversed, current is blocked. Researchers have tried for decades ...
Self-assembled monolayers create p-n junctions in graphene films
Researchers are creating graphene p-n junctions by transferring films of the electronic material to substrates that have been patterned by compounds that are either strong electron donors or electron acceptors.
Organic solar cells more efficient with molecules face-to-face
(Phys.org) —New research from North Carolina State University and UNC-Chapel Hill reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor ...
Lost frog DNA revived
As part of a "Lazarus Project" to try to bring the Australian gastric-brooding frog back from extinction a UNSW-led team has succeeded in producing early stage cloned embryos containing the DNA of the frog, ...
From a drop of blood, a clone
Over the last few decades, scientists have drawn upon a powerful arsenal of biotechnology techniques to establish a wide variety of genetically engineered mouse strains. These animals represent invaluable ...
No pet hates as dog donates blood to save cat
Traditional animal rivalries were set aside in New Zealand when a dog's blood was used to save the life of a poisoned cat in a rare inter-species transfusion, reports said Wednesday.
By boosting cloning efficiency, scientists unlock the potential to 'mass-produce' valuable animal strains
Long before humans understood the principles of genes and heritability, they were already shaping animal evolution through selective breeding. The various domesticated species we cultivate today are the product ...
Bioremediation used to alleviate surface water pollution
European research has investigated the possibility of using naturally occurring microbes to bio-decontaminate groundwater, a source of organic solvent pollutants in surface water.
For the first time, a donor mouse has been cloned using a drop of peripheral blood from its tail
From obesity to substance abuse, from anxiety to cancer, genetically modified mice are used extensively in research as models of human disease. Researchers often spend years developing a strain of mouse with ...
Using engineering to help microbes destroy contaminates in soil and groundwater
There are several advantages to having natural microbes break down contaminants in soil and groundwater. First, it's cost effective. More importantly, the process involves using native microorganisms that ...
Animal moms customize milk depending on baby's sex
A special blend of mother's milk just for girls? New research shows animal moms customize their milk in surprising ways depending on whether they have a boy or a girl.
Online effort nets $1.3M to restore Tesla's NY lab
(AP)—Internet "crowdfunding" has raised $1.3 million to restore a New York laboratory once used by Nikola Tesla.
Clones of clones can make clones
Since the first reports of successful cloning of mammals by somatic cell nuclear transfer, concerns have been raised about the efficiency and repeatability of cloning techniques, and the health of cloned ...
