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.

Hybrid 'Super Mosquito' Resistant to Insecticide-treated Bed Nets
Interbreeding of two malaria mosquito species in the West African country of Mali has resulted in a "super mosquito" hybrid that's resistant to insecticide-treated bed nets. "It's 'super' with respect to its ability to survive exposure to the insecticides on treated bed nets," said medical entomologist Gregory Lanzaro of UC Davis, who led the research team.

Ancient Maize Followed Two Paths into the Southwest
After it was first domesticated from the wild teosinte grass in southern Mexico, maize, or corn, took both a high road and a coastal low road as it moved into what is now the U.S. Southwest, reports an international research team that includes a UC Davis plant scientist and maize expert.

Unraveling Controls for Plant Root Growth
Green shoots are a sign of spring, but growing those shoots and roots is a complicated process. Now researchers at UC Davis and the University of Massachusetts Amherst have for the first time described part of the network of genetic controls that allows a plant to grow.

Study Casts Doubt on Mammoth-killing Cosmic Impact
Rock soil droplets formed by heating most likely came from Stone Age house fires and not from a disastrous cosmic impact 12,900 years ago, according to new research from the University of California, Davis. The study, of soil from Syria, is the latest to discredit the controversial theory that a cosmic impact triggered the Younger Dryas cold period.

The Winds of Titan
As sand dunes march across the Sahara, vast dunes cross the surface of Saturn's largest moon, Titan. New research from a refurbished NASA wind tunnel reveals the physics of how particles move in Titan's methane-laden winds and could help to explain why Titan's dunes form in the way they do. The work is published online Dec. 8 in the journal Nature.

Bitter Food but Good Medicine from Cucumber Genetics
High-tech genomics and traditional Chinese medicine come together as researchers identify the genes responsible for the intense bitter taste of wild cucumbers. Taming this bitterness made cucumber, pumpkin and their relatives into popular foods, but the same compounds also have potential to treat cancer and diabetes.

First Amphibious Ichthyosaur Discovered, Filling Evolutionary Gap
The first fossil of an amphibious ichthyosaur has been discovered in China by a team led by researchers at the University of California, Davis. The discovery is the first to link the dolphin-like ichthyosaur to its terrestrial ancestors, filling a gap in the fossil record. The fossil is described in a paper published in advance online Nov. 5 in the journal Nature.
