In order to see how many viruses are present in a patient’s biological fluid sample, bulky and costly devices such as fluorescence microscopes are typically used – not a good solution for developing nations or remote locations. That’s why sci… Continue reading Low-cost device utilizes a smartphone to count viruses
As crop plants “breathe” through the pores in their leaves, they release an assortment of volatile organic compounds (VOCs) into the air. A new smartphone-connected device analyzes those chemicals within a matter of minutes, detecting and ide… Continue reading Smartphone device identifies plant diseases on the spot
According to a new study, seniors wishing to boost their cognitive performance would likely do well to drink plenty of Montmorency tart cherry juice. Improvements observed in test subjects who drank the juice may be due to “bioactive compound… Continue reading For better senior brain function, tart cherry juice may be the way to go
Living in the soil, roundworms can infect plants via their roots, which is why many plants have evolved to produce an immune response when the worms are detected. Now, scientists have harnessed that response to create an eco-friendly form of … Continue reading Wormy chemicals used to trick crops into protecting themselves
First of all, no one is suggesting that if you suffer from depression and anxiety, you should drink a lot of red wine. That would ultimately not help the situation. However, it turns out that a plant-derived compound in the wine – known as re… Continue reading Compound in red wine may decrease depression and anxiety
Do trees always exist as single organisms, or can each tree also serve as part of a linked “superorganism?” A recent finding in New Zealand suggests the latter, as a tree stump there has apparently remained alive by joining roots with its nei… Continue reading Amazingly still-alive stump points to a new understanding of trees
The most numerous of organisms on Earth, bacteriophages are viruses that infect and kill bacteria. Now, scientists have grown enough of them to create a self-healing hydrogel that’s made almost entirely of the things. It could have important … Continue reading Self-healing antibacterial gel is made of viruses
With a few experimental exceptions, bandages generally just cover wounds, as opposed to actively healing them. That’s not the case with a new heat-activated “active adhesive dressing” (AAD), however, which forgoes antibiotics while mimicking … Continue reading Hydrogel bandage uses body heat to speed wound healing
The over-abundance or lack of certain types of gut bacteria has been linked to everything from depression to heart disease to childhood asthma. Non-invasively determining which microbes make up a person’s “gut microbiome,” however, can be dif… Continue reading Microbiome-assessing capsule gathers gut bacteria
Fans of the Mission Impossible movies may recall the agents’ use of a slim, throat-mounted device that changes the user’s voice. Well, Chinese scientists have now developed something similar, that could one day allow the mute to speak &hellip… Continue reading Stick-on device could let the speechless "speak"
