Published Bizarre new fossils shed light on ancient plankton
(via sciencedaily.com) Original source Recently discovered microfossils date back half a billion years. Resembling modern-day algae, they provide insight into early life in our oceans.
Published Sunflower extract fights fungi to keep blueberries fresh
(via sciencedaily.com) Original source Opening a clamshell of berries and seeing them coated in fuzzy mold is a downer. And it's no small problem. Gray mold and other fungi, which cause fruit to rot, lead to significant economic losses and food waste. Now, researchers report that compounds from sunflower crop waste prevented rotting in blueberries. They suggest the food industry could use these natural compounds to protect against post-harvest diseases.
Published How eggs of the Zika-carrying mosquito survive desiccation
(via sciencedaily.com) Original source Eggs of the mosquito that carries Zika virus can tolerate extended desiccation by altering their metabolism, according to a new study. The finding offers potential new ways to control the spread of this mosquito.
Published Bacteria can enhance host insect's fertility with implications for disease control
(via sciencedaily.com) Original source New research reveals how the bacteria strain Wolbachia pipientis enhances the fertility of the insects it infects, an insight that could help scientists increase the populations of mosquitoes that do not carry human disease.
Published Scientists develop new method to create stable, efficient next-gen solar cells
(via sciencedaily.com) Original source Next-generation solar materials are cheaper and more sustainable to produce than traditional silicon solar cells, but hurdles remain in making the devices durable enough to withstand real-world conditions. A new technique could simplify the development of efficient and stable perovskite solar cells, named for their unique crystalline structure that excels at absorbing visible light.
Published The microbiome of fruit and vegetables positively influences diversity in the gut
(via sciencedaily.com) Original source In a meta-study, a research team has provided evidence that the consumption of fruit and vegetables contributes positively to bacterial diversity in the human gut.
Published Finding the genes that help kingfishers dive without hurting their brains
(via sciencedaily.com) Original source Scientists studied the genomes of 30 kingfisher species to try to identify the genes that allow kingfishers to dive headfirst into water without huring their brains. The researchers found that the diving birds have unusual mutations to the genes that produce tau: a protein that helps stabilize tiny structures in the brain, but which can build up in humans with traumatic brain injuries or Alzheimer's disease. The researchers suspect that these variations in the kingfishers' tau proteins might protect their brains when they dive.
Published Scientists uncover cause of mysterious deaths of elephants in Zimbabwe
(via sciencedaily.com) Original source A bacterium, closely associated with deadly septicaemia, could have caused the deaths of six African elephants in Zimbabwe and possibly more in neighboring countries. The findings place infectious diseases on the list of pressures on African elephants, whose populations continue to be under threat.
Published Children as young as four eat more when bored
(via sciencedaily.com) Original source A new study has shown that children as young as four years old eat 79% more calories when they are bored, compared to when they are in a neutral mood.
Published Study shows engineered gut bacteria can treat hypertension
(via sciencedaily.com) Original source Newly published research proves that it's possible to treat high blood pressure by using specially engineered Lactobacillus paracasei to produce a protein called ACE2 in the gut, reducing gut angiotensin II and, in turn, lowering blood pressure. The study, done in lab rats that are predisposed to hypertension and unable to naturally produce ACE2, opens new doors in the pursuit of harnessing our body's own microbiome to regulate blood pressure.
Published How to slow the spread of deadly 'superbugs'
(via sciencedaily.com) Original source Harnessing new advances in genomic surveillance technology could help detect the rise of deadly 'superbugs'.
Published Gut fungi's lasting impact on severe COVID-19 immune response
(via sciencedaily.com) Original source Certain gut-dwelling fungi flourish in severe cases of COVID-19, amplifying the excessive inflammation that drives this disease while also causing long-lasting changes in the immune system, according to a new study. This discovery identifies a group of patients who may benefit from specialized, but yet-to-be determined treatments.
Published Discovery finds ferns produce crop-saving insecticide
(via sciencedaily.com) Original source Researchers have solved the structure of a novel insecticidal protein that is effective in protecting major crop plants like corn and soybean from pests and is naturally produced by ferns.
Published Fungal evolution discovered: Mycena can now invade living hosts
(via sciencedaily.com) Original source Biologists have long known mushrooms of the genus Mycena, commonly known as bonnet mushrooms, as fungi that live off of dead trees and plants. New research demonstrates that bonnets can also find their ways into young, healthy trees and plants, where they try to cooperate. In doing so, they have made an evolutionary leap which challenges our understanding of the ecological roles of fungi.
Published Researchers develop DANGER analysis tool for the safer design of gene editing
(via sciencedaily.com) Original source A team of researchers has developed a software tool that provides a way for the safer design of genome editing in all organisms with a transcriptome. For about a decade, researchers have used the CRISPR technology for genome editing. However, there are some challenges in the use of CRISPR. The new analysis system overcomes these challenges and allows researchers to perform safer on- and off-target assessments without a reference genome. It holds the potential for applications in medicine, agriculture, and biological research.
Published Contaminants in cannabis and hemp flowers create potential for health risks
(via sciencedaily.com) Original source Cannabis use, even for medical purposes, could make some people sick due to harmful fungi that contaminate the plants. That is the finding of a recently published peer-reviewed journal article, whose authors recommend further study and consideration of changes to regulations to protect consumers, especially those who are immunocompromised. They examined data, previous studies, and U.S. and international regulations related to the cannabis and hemp industry.
Published Moving muscle fibers with magnets 'programs' how they align within tissue
(via sciencedaily.com) Original source Stimulating muscle fibers with magnets causes them to grow in the same direction, aligning muscle cells within tissue. The findings offer a simpler, less time-consuming way for medical researchers to program muscle cell alignment, which is strongly tied to healthy muscle function.
Published How cord-like aggregates of bacteria lead to tuberculosis infections
(via sciencedaily.com) Original source The ability of Mycobacterium tuberculosis (MTB), a serious respiratory infection, to form snake-like cords was first noted nearly 80 years ago. Investigators report the biophysical mechanisms by which these cords form and demonstrate how several generations of dividing bacteria hang together to create these structures that enable resistance to antibiotics.
Published Pivotal breakthrough in adapting perovskite solar cells for renewable energy
(via sciencedaily.com) Original source A huge step forward in the evolution of perovskite solar cells will have significant implications for renewable energy development.
Published Potential for injectable 'chemical vaccine' for malaria using atovaquone
(via sciencedaily.com) Original source Researchers looking to develop a long-acting, injectable malaria preventive using atovaquone have shown in a new study that resistance may not be the challenge scientists thought it was, particularly when using atovaquone as a malaria preventive. Malaria parasites in infected patients being treated with atovaquone tend to develop a resistance to the drug. Because of this, atovaquone by itself is not used as a malaria treatment nor has not been seen as a strong candidate for use as a preventive.
