Nov. 16, 2015 — Researchers have revealed how a jellyfish -- those commonplace sea pests with stinging tentacles -- have evolved over time into 'really weird' microscopic organisms, made of only a few ... read more

Gene Drive Reversibility Introduces New Layer of Biosafety

Nov. 16, 2015 — A research team demonstrates effective safeguarding mechanisms for working with gene drives and unveils a first-of-its-kind method for reversing the changes they ... read more

Nov. 16, 2015 — Taking genetic engineering to the next level, researchers are creating modular, programmable genetic circuits that control specific plant ... read more

Nov. 16, 2015 — Signalling processes in organisms are governed by specific extracellular and intracellular interactions and involve hundreds of different functionally highly versatile receptors situated in cell ... read more

Nov. 13, 2015 — A gene found only in a single plant species can increase protein content when introduced into staple crops, report scientists. The research has implications for a wide array of crops, especially for ... read more

Nov. 13, 2015 — In the 19th century, Darwin's most vocal scientific advocate was Thomas Henry Huxley, who is also remembered as a pioneer of the hypotheses that birds are living dinosaurs. He noticed several ... read more

Nov. 12, 2015 — Cryptosporidium parvum is a gastrointestinal parasite that can cause moderate to severe diarrhea in children and adults, and deadly opportunistic infection in AIDS patients. Because C. parvum is ... read more

Nov. 12, 2015 — Most animals reproduce by laying eggs. As the embryo develops, its feeds on the egg yolk. No egg yolk, no offspring, then? Not always. Biologists have discovered an exception to the rule: the eggs of ... read more

Nov. 12, 2015 — The source of any life involves the duplication (or replication) of DNA, a mechanism that is essential to cell division. A team of biologists has recently performed the most exhaustive analysis to ... read more

Nov. 11, 2015 — Ants may respond to disturbances in their nest as one highly organized 'superorganism', according to a new ... read more

Nov. 11, 2015 — The newly described Probrachylophosaurus bergei, a member of the Brachylophosaurini clade of dinosaurs, has a small flat triangular bony crest extending over the skull and may represent the ... read more

Nov. 11, 2015 — Materials science researchers have used computational modelling to shed light on precisely how charged gold nanoparticles influence the structure of DNA and RNA -- which may lead to new techniques ... read more

Coronavirus Breakthrough: Protein Mutation Affects Spread and Virulence of Respiratory Virus

Nov. 10, 2015 — Researchers have discovered that a mutation in a coronavirus protein slows the spread of the virus in the central nervous system and reduces its neurovirulence. It is the first time that this ... read more

Nov. 9, 2015 — When scientists presented evidence of an ancient, fossilized brain a few years ago, it challenged the long-held notion that brains don't fossilize. Now, seven new specimens have been unearthed, ... read more

Packaging and Unpacking of the Genome

Nov. 6, 2015 — DNA represents a dynamic form of information, balancing efficient storage and access requirements. Packaging approximately 1.8m of DNA into something as small as a cell nucleus is no mean feat, but ... read more

Nov. 5, 2015 — Little is known about the mechanisms that regulate the release of steroid hormones from endocrine tissues. The commonly accepted understanding, noted in textbooks, is that simple diffusion is at ... read more

Nov. 5, 2015 — The DNA in our cells is folded into millions of small packets, like beads on a string, allowing our two-meter linear DNA genomes to fit into a nucleus of only about 0.01 mm in diameter. However, ... read more

No New Heart Muscle Cells in Mice After the Newborn Period

Nov. 5, 2015 — New heart muscle cells in mice are mainly formed directly after birth, new research shows. After the neonatal period the number of heart muscle cells does not change, and heart growth occurs only by ... read more

Nov. 4, 2015 — Researchers announce findings from the first-of-its-kind analysis on an invertebrate sight system. The research focused on eye growth during the larval stages of the Sunburst Diving Beetle - which ... read more

New Test for Ancient DNA Authenticity Throws Doubt on Stone Age Wheat Trade

Nov. 3, 2015 — A new method reliably tests whether DNA shows ancient or modern patterns of biochemical change. This has recently cast doubt on the authenticity of what was thought to be evidence of a Stone Age ... read more
