Scientists have decoded the genomes of two species of shark, bringing the grand total of sequenced shark genomes to three.
Ig Nobel awards: Silly experiments that strike gold
Amanda writes about the Ig Nobel awards after founder Marc Abrahams visited nerdnite Tokyo. Science at its best!
A self-powered heart monitor taped to the skin
A group of scientists have developed a human-friendly, ultra-flexible organic sensor powered by sunlight, which acts as a self-powered heart monitor.
AI used to detect fetal heart problems
Researchers have developed a novel system that can automatically detect abnormalities in fetal hearts in real-time using artificial intelligence (AI). ???❤️
Protostars that exhibit large diversity in organic compounds
A survey of a molecular cloud has found that the organic chemical makeup of protostars varies considerably.
Scientists solve epigenetic barriers to cloning
Scientists show that two epigenetic factors improve the success rate of cloning via somatic cell nuclear transfer.
Transgenic plants 🌱🌿on acid survive without water
Scientists designed transgenic plants that survive drought-like conditions by bumping up acetic acid production only when water is scarce.
Two genes that regulate how much we dream
An international research team led by RIKEN BDR has identified a pair of genes that regulate how much REM (dream) and non-REM sleep an animal experiences.
Flies use fecal deposits as pheromones
Bioluminescence imaging of fly brains reveals neurons sensitive to fly poo laced with pheromones (you can see the fecal “landmark” in the dotted circle). Need we say more?
Hippocampal memory isn’t all about place cells
Scientists have found evidence that hippocampal memories of experience are not stored in place cells.
Summer fun: how plants beat the heat
Scientists have discovered a gene that allows plants to cope with extreme heat by changing the composition of chloroplast membranes.
Freedom from fear ?♀️
Researchers discover a dopaminergic circuit in the brain that allows fear associations to disappear when there isn’t anything to be afraid of anymore.
Blue gene regulation helps plants respond properly to light
Blue light alters some gene expression in plants by changing the transcription start sites to downstream locations.
Out on a limb: the many ‘brains’ of the octopus
Learn how (neurologically) cool octopus arms are (as if you didn’t already know).
Mutation links bipolar disorder to mitochondrial disease
ANT1 mutations found in bipolar disease that affect mitochondria lead to hyperexcitable serotonergic neuronal activity in the brain.
My science communication journey in Tokyo
New contributor and nuclear physicist Sarah Naimi talks about her recent experience in science communication at a recent scicom event in Tokyo.
Gene linked to intellectual ability affects memory replay in mice
Scientists have discovered a gene in mice that allows memory replay at rest, a process necessary for forming long-lasting memories in mice.
