Sex, Tools And Chromosomes

Published: April 12, 2012.
Released by University of California - Davis  

Researchers at the University of California, Davis have discovered a key tool that helps sperm and eggs develop exactly 23 chromosomes each. The work, which could lead to insights into fertility, spontaneous miscarriages, cancer and developmental disorders, is published April 13 in the journal Cell.

Rat Poison at Marijuana Farms Is Killing Increased Numbers of Rare Forest Mammal
The situation is growing worse for fishers being poisoned by rodenticides on illegal marijuana grow sites in California, according to a study by a team of researchers led by the University of California, Davis, and the Integral Ecology Research Center, based in Blue Lake, California.

Early Intervention in Dyslexia Can Narrow Achievement Gap, UC Davis Study Says
Identifying children with dyslexia as early as first grade could narrow or even close the achievement gap with typical readers, according to a new study by researchers at the University of California, Davis, and Yale University. The data indicate that it is no longer acceptable to wait until a child is in third grade or later before undertaking efforts to identify or address dyslexia.

Often Decried, Polygyny May Sometimes Have Advantages
Much of the world frowns on the practice of polygamy. Most countries around the globe ban or restrict marriages to more than one spouse at a time. And polygyny--where one husband has more than one wife--is decried by the United Nations Human Rights Committee and women's rights organizations as discriminatory to women. But a new study of polygyny in Tanzania finds that the practice of sharing a husband may, in some circumstances, lead to greater health and wealth for women and their children.

Sixth Sense: How Do We Sense Electric Fields?
A variety of animals are able to sense and react to electric fields, and living human cells will move along an electric field, for example in wound healing. Now a team lead by Min Zhao at the UC Davis Institute for Regenerative Cures has found the first actual "sensor mechanism" that allows a living cell detect an electric field. The work is published Oct. 9 in the journal Nature Communications.

Room Temperature Magnetic Skyrmions, a New Type of Digital Memory?
An exotic, swirling object with the sci-fi name of a "magnetic skyrmion" could be the future of nanoelectronics and memory storage. Physicists at UC Davis and the National Institute of Standards and Technology (NIST) have now succeeded in making magnetic skyrmions, formerly found at temperatures close to absolute zero, at room temperature.

Cold Rush: Bird Diversity Higher in Winter Than Summer in Central Valley
During the warmer months, the air surrounding California's rivers and streams is alive with the flapping of wings and chirping of birds. But once the buzz and breeding of spring and summer are over, these riparian areas grow quiet. Sometimes it seems as though there are hardly any birds there at all. Not so, according to a study from the UC Davis Department of Wildlife, Fish and Conservation Biology.

Southern California Wildfires Show Split Personalities
Wildfires have ravaged regions of Southern California at an increasing rate over the past few decades, and scientists from three University of California campuses and partner institutions are predicting that by mid-century, a lot more will go up in flames.

Nanoporous Gold Sponge Makes DNA Detector
Sponge-like nanoporous gold could be key to new devices to detect disease-causing agents in humans and plants, according to UC Davis researchers.
