Published Algae's surprising potential to help ease climate change worries
(via sciencedaily.com) Original source The key to bringing global net-zero goals into reach may be algae, say researchers. Studies show impressive success of certain microalgae varieties to remove CO2 from the atmosphere then break it down into useful materials.
Published Zika infection in pregnant macaques slows fetal growth
(via sciencedaily.com) Original source Zika virus infection in pregnant rhesus macaques slows fetal growth and affects how infants and mothers interact in the first month of life, according to a new study. The work has implications for both humans exposed to Zika virus and for other viruses that can cross the placenta, including SARS-CoV2, responsible for the COVID-19 pandemic.
Published Massive space explosion observed creating elements needed for life
(via sciencedaily.com) Original source Scientists have observed the creation of rare chemical elements in the second-brightest gamma-ray burst ever seen -- casting new light on how heavy elements are made.
Published Scientists discover molten layer covering Martian core
(via sciencedaily.com) Original source NASA's InSight mission to Mars helped scientists map out Mars' internal structure, including the size and composition of its core, and provided general hints about its tumultuous formation. But findings from a new paper could lead to reanalysis of that data. An international team of researchers discovered the presence of a molten silicate layer overlying Mars' metallic core -- providing new insights into how Mars formed, evolved and became the barren planet it is today.
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 Solar farms in space are possible
(via sciencedaily.com) Original source It's viable to produce low-cost, lightweight solar panels that can generate energy in space, according to new research.
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 Astrophysicists scan the Galaxy for signs of life
(via sciencedaily.com) Original source Astrophysicists are scanning the Universe for 'technosignatures' emanating from distant planets that would provide support for the existence of intelligent, alien life. Researchers plan to monitor millions of star systems.
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 Curiosity rover finds new evidence of ancient Mars rivers, a key signal for life
(via sciencedaily.com) Original source New analysis of data from the Curiosity rover reveals that much of the craters on Mars today could have once been habitable rivers.
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 Researchers capture first images of a radio 'ring of fire' solar eclipse
(via sciencedaily.com) Original source Researchers have recorded images of a solar eclipse with the 'ring of fire' effect in radio waves.
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.
