Australian experiment wipes out over 80% of disease-carrying mosquitoes

In an experiment with global implications, Australian scientists have successfully wiped out more than 80% of disease-carrying mosquitoes in trial locations across north Queensland. The experiment, conducted by scientists from the Commonwealth Scientific and Industrial Research Organization (CSIRO) and James Cook University (JCU), targeted Aedes aegypti mosquitoes, which spread deadly diseases such as dengue fever…

Gene-editing technique cures genetic disorder in utero

Researchers at Carnegie Mellon University and Yale University have for the first time used a gene editing technique to successfully cure a genetic condition in a mouse model. Their findings, published in Nature Communications, present a promising new avenue for research into treating genetic conditions during fetal development. An estimated 8 million children are born each…

How mangroves help keep the planet cool

Coastal scientists have developed a new global framework to more accurately assess how mangroves along different types of coastlines from deltas to lagoons store carbon in their soil. They found that previous studies have underestimated the blue carbon levels in mangroves by up to 50 percent in some regions and overestimated levels by up to…

Evolution of Testes: Molecular Vestiges

The loss of anatomical features is a frequent evolutionary event. For example, humans and other great apes have lost their tail and whales have lost their legs. The most convincing evidence comes from the presence of vestiges in fossils. Unfortunately, the fossil record preserves predominantly vestiges of hard structures such as bones or teeth. Consequently,…

Global warming can turn monarch butterflies’ favorite food into poison

LSU researchers have discovered a new relationship between climate change, monarch butterflies and milkweed plants. It turns out that warming temperatures don't just affect the monarch, Danaus plexippus, directly, but also affect this butterfly by potentially turning its favorite plant food into a poison. Bret Elderd, associate professor in the LSU Department of Biological Sciences, and…

Two new creatures discovered from dawn of animal life

Earth's first complex animals were an eclectic bunch that lived in the shallow oceans between 580-540 million years ago. The iconic Dickinsonia -- large flat animals with a quilt-like appearance -- were joined by tube-shaped organisms, frond-like creatures that looked more like plants, and several dozen other varieties already characterized by scientists. Add to that list two…

NASA Finds Ancient Organic Material, Mysterious Methane on Mars

NASA’s Curiosity rover has found new evidence preserved in rocks on Mars that suggests the planet could have supported ancient life, as well as new evidence in the Martian atmosphere that relates to the search for current life on the Red Planet. While not necessarily evidence of life itself, these findings are a good sign…

Trio of genes supercharged human brain evolution

Three nearly identical genes could help explain how 0.5 liters of gray matter in early human ancestors became the 1.4-liter organ that has made our species so successful and distinctive. The newly identified genes could also help explain how brain development sometimes goes wrong, leading to neurological disorders. The genes, descendants of an ancient developmental…

Secret to longevity may lie in the microbiome and the gut

You are what you eat. Or so the saying goes. Science now tells us that we are what the bacteria living in our intestinal tract eat and this could have an influence on how well we age. Building on this, McGill University scientists fed fruit flies with a combination of probiotics and an herbal supplement…
