   Ancient remains, once thought to be a key link in the evolution of mankind, have now been shown to be 400,000 years too young to be a part of man’s family tree.

3. Dramatic shift from simple to complex marine ecosystems occurred 250M years ago at mass extinction
   11-23-2006 · EurekAlert!
   The biggest mass extinction did more than eliminate species: It fundamentally changed the basic ecology of the oceans. Ecologically complex marine communities displaced simple communities, setting a pattern that has continued ever since.This striking change has escaped detection because previous research relied on single numbers -- such as the number of species alive at one time -- to track diversity. New research examines the relative abundance of marine life forms in communities over 540 million years.

4. UC Davis researchers discover key to body's ability to detect subtle temperature changes
   02-26-2007 · EurekAlert!
   Scientists have long known the molecular mechanisms behind most of the body's sensing capabilities. Vision, for example, is made possible in part by rhodopsin, a pigment molecule that is extremely sensitive to light. It is involved in turning photons into electrical signals that can be decoded by the brain into visual information. But how the human body is able to sense a one-degree change in temperature has remained a mystery.

5. Treatment of asthma: Stepping up treatment and also stepping it down
   04-09-2007 · EurekAlert!
   Asthma symptoms vary greatly among individuals and vary at times with each individual. In this comprehensive study in the April issue of Mayo Clinic Proceedings, researchers address the prevalence and process of step-down therapy as symptoms subside. Of the 397 adults and children studied, 64 percent had at least one change in medication dose during the two years of the study. Most changes were step-up in doses during an asthma flare. Step-down changes were far less common.

6. New study rewrites evolutionary history of vespid wasps
   03-01-2007 · EurekAlert!
   Scientists at the University of Illinois have conducted a genetic analysis of vespid wasps that revises the vespid family tree and challenges long-held views about how the wasps’ social behaviors evolved. The researchers found genetic evidence that eusociality (the reproductive specialization seen in some insects and other animals) evolved independently in two groups of vespid wasps.

8. Ancient coral reef tells the history of Kenya's soil erosion
   04-10-2007 · EurekAlert!
   Coral reefs, like tree rings, are natural archives of climate change. But oceanic corals also provide a faithful account of how people make use of land through history, says Stanford University scientist Robert B. Dunbar. In a recent study published in Geophysical Research Letters, Dunbar and his colleagues used coral samples from the Indian Ocean to create a 300-year record of soil erosion in Kenya.

9. Changing climate will challenge Northeast agriculture, CU expert warns
   07-11-2007 · EurekAlert!
   Farmers will grapple with new and aggressive crop pests, summer heat stress and water problems that could strain family farms to the limit, warns David Wolfe, a Cornell expert on the effects of climate change on agriculture. His gloomy assessment was part of a report by the Northeast Climate Impacts Assessment Synthesis Team, presented July 11 at a press conference at the New York Botanical Garden.

    Evaluating changes in range size of land bird species using Millenium Ecosystem Assessment scenarios reveals that land conversion, as well as climate change, will lead to the decline of many species, particularly those in the tropics.
