The brain’s GPS has a buddy system
In addition to encoding self location, brain cells in the rat hippocampus act like a GPS that encodes the location of other rats.
Leaky plants bad for drought resistance
The KAI2 receptor for compounds found in smoke helps plants retain water and survive during drought.
Helping the body clock keep its cool
Two parallel temperature-responsive mechanisms ensure that circadian rhythms are not skewed by changes in temperature
The stars align
The stars align. That’s what you say, when things work out perfectly. In the case of an eclipse, of course, it’s not stars that align but rather the moon and sun.
What’s that smell? The advantage of sniffing
Rhythmic sniffing boosts phase-coded neuronal signals in the mouse olfactory bulb that allow odors to be identified.
Quantum dots light up cancer with a little help
Researchers have found a small connecting protein that can help make quantum dot-based probes for biomedical imaging.
Most precise measurement ever of proton magnetic moment
Using a sophisticated setup, scientists have made the most precise measurement to date of the proton magnetic moment.
Proton and antiproton still seem identical
Using a novel two-particle measurement method, scientists have measured the magnetic moment of the antiproton at a precision 350 times higher than any previous measurement.
Microcolumns: elementary neuronal units that carpet the (mouse) brain
A hexagonal lattice organizes major cell types in the cerebral cortex, with similar cells synchronizing their activity in microcolumns.
Jupiter’s volcano-powered auroral lights
A collaborative effort used data from NASA’s Juno spacecraft to explain the transient auroras found on Jupiter.
Hepatoma (liver cancer) blocked by a sugar look-a-like
A sugar (fucose) analog can prevent liver cancer (hepatoma) from invading healthy liver cells.
Random movements help color-detecting cells form the proper pattern
Scientists have used a mathematical model to explain why zebrafish cone cells in the eye are arranged in a specific pattern in all individuals.
Visualizing chick-brain morphogenesis
A new statistical-based method provides insight into the morphogenesis of developing organs.
Skin-like wearable electronics
Sensors made from stretchable nanomesh allow skin to breathe naturally while continuously monitoring patient health.
Solar cells you can put in the wash
Scientists have developed ultra-thin photovoltaic solar cells that can be incorporated into fabric and even washed.
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.
