Why being sick can create anxiety
Researchers have linked changes in mouse immune-cell metabolism to anxiety-related behavior and alterations in brain chemistry.
Plant hormone combats dehydration
Scientists show that CLE25 is a plant hormone that travels from roots to leaves and helps close stomata in times of dehydration stress.
Heat shock system helps dried up bug come back to life
An international collaboration has determined that cooption of the Heat Shock Factor (HSF) gene system is what allows larvae of the sleeping chironomid to be able to survive severe desiccation.
In living color: imaging the brain with synthetic bioluminescence
A new way to image the brain from outside the head using bioluminescence.
Deep-brain exploration with nanomaterials
A new way to optogenetically activate neurons deep in the brain using infrared light and upconversion nanoparticles. It’s non-invasive!
Running away from carbon dioxide: the terminal connection
Even fish want to avoid carbon dioxide. Now we know that they can because of chemosensation and the Terminal Nerve.
Rainbow engineering to make the brain glow
Bar talk about tinkering with bioluminescent molecules from jellyfish, corals, and algae, figuring out how they work, and making them more useful for brain science.
Geostationary satellite enables better precipitation and flood predictions
Data from the Himawari-8 geosynchronous satellite was used in weather simulations to improve forecasts of sudden precipitation and tropical storm development.
Clean and green: a moss that removes lead (Pb) from water
Scientists show that the moss Funaria hygrometrica can remove harmful lead from water when in the protonema stage of development.
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.
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.
