Large-scale edible insect farming needed to ensure global food security
Editing the genome: New method allows scientists to insert multiple genes in specific locations, delete defective genes
Researchers at MIT, the Broad Institute and Rockefeller University have developed a new technique for precisely altering the genomes of living cells by adding or deleting genes. The researchers say the technology ...
Researchers identify key cellular organelle involved in gene silencing
RNA molecules, made from DNA, are best known for their role in protein production. MicroRNAs (miRNAs), however, are short (~22) nucleotide RNA sequences found in plants and animals that do not encode pro ...
Living organisms need antifreeze to survive in the cold
(Phys.org)—If you thought antifreeze was only something that was necessary to keep your car from freezing up in the winter, think again. Plants and animals living in cold climates have natural antifreeze proteins (AFPs) ...
Researchers discover molecule that allows for controlling animal movements using light
(Phys.org)— A diverse group of researchers from the U.S. and China has discovered a molecule that allows for controlling the movements of animals using only light. In their paper published in the journal Nature Chemical Bi ...
Chemists develop nose-like sensor array to 'smell' cancer diagnoses
In the fight against cancer, knowing the enemy's exact identity is crucial for diagnosis and treatment, especially in metastatic cancers, those that spread between organs and tissues. Now chemists led by ...
Programming cells: The importance of the envelope
In a project that began with the retinal cells of nocturnal animals and has led to fundamental insights into the organization of genomic DNA, researchers from Ludwig-Maximilians-Universitaet (LMU) in Munich show how the nuclear ...
X-rays reveal why sea urchins are no easy prey
(PhysOrg.com) -- The spine of a sea urchin is 99.9% chalk, a very common material forming tiny crystals that are very hard but easy to break apart. Scientists have now discovered how these marine animals use ...
Dance of water molecules turns fire-colored beetles into antifreeze artists
Certain plants and animals protect themselves against temperatures below freezing with antifreeze proteins. How the larva of the beetle Dendroides canadensis manages to withstand temperatures down to -30 ...
Researchers discover novel approach to stimulate immune cells
Researchers at Rutgers University have uncovered a new way to stimulate activity of immune cell opiate receptors, leading to efficient tumor cell clearance.
Researchers induce freezing tolerance in fruit fly
(PhysOrg.com) -- Most of what is known about the ability of some cold blooded animals and several insects to survive having their body temperature fall below freezing has led to the conclusion that those organisms ...
Molecular mechanism triggering Parkinson's disease identified
Scientists at the Stanford University School of Medicine have identified a molecular pathway responsible for the death of key nerve cells whose loss causes Parkinson's disease. This discovery not only may explain how a genetic ...
Warming temperatures cause aquatic animals to shrink the most
Flatworms' minimalist approach to cell division reveals molecular architecture of human centrosome
Researchers at the University of California, San Francisco and the Stowers Institute for Medical Research have discovered that planarians, tiny flatworms fabled for their regenerative powers, completely lack ...
