UZH plant researchers have tested newly developed wheat lines with improved resistance in field trials. They have demonstrated that a combination of two variations of a resistance gene provides wheat with better protection against the fungal disease.
Male sea turtles are disappearing and not just in Australia. FAU researchers found that 97 to 100 percent of hatchlings in southeast Florida have been female since 2002. They are the first to show why and how moisture conditions inside the nest in addition to heat affect the development and sex ratios of turtle embryos, using a novel technique they developed to estimate sex ratios with a male-specific, transcriptional molecular marker Sox9.
A new study of infants born in withdrawal due to opioid exposure in utero shows a dramatic increase in torticollis -- an abnormal twisting of the neck. Many of the infants also had plagiocephaly -- a flattening of the head often seen in conjunction with torticollis.
Fanconi anemia is a human genetic disorder with severe effects, including an increased risk of cancer and infertility. Research in plants helps us understand the disease in humans, showing how a key protein functions in the exchange of genetic material.
Geneticists have solved a century-old mystery by discovering a remarkable mechanism that enables plants to count their chromosomes. Their ability to detect imbalances in male and female contributions to the next generation determines their progeny's viability and fertility.
Scientists have solved a longstanding puzzle of how cells are able to tightly package lengthy strands of DNA when they divide -- an essential process for growth, repair and maintenance in living organisms.
Post-fire logging, rather than the wildfires themselves, is responsible for the steep decline in territory occupancy of the rare spotted owls living in the forests of California. The study's results coincide with the strong consensus among hundreds of US scientists opposing post-fire logging operations due to a wide range of ecological harms. The research is published in the open-access journal Nature Conservation.
A new study led by Joel Berger has uncovered previously unknown effects of rain-on-snow events, winter precipitation and ice tidal surges on the muskoxen.
Scientists in the USC Stem Cell laboratory of Gage Crump have revealed how key genes guide the development of the jaw in zebrafish. These findings may offer clues for understanding craniofacial anomalies in human patients, who sometimes carry a mutation in equivalent genes.
Women have many options for oral contraceptives that are safe, effective and reversible, but despite decades of research, men have none. Now, scientists report a rat study in ACS' Journal of Medicinal Chemistry that shows they finally have a good lead for a male birth control pill. It's based on ouabain, a plant extract that African warriors and hunters traditionally used as a heart-stopping poison on their arrows.
