‘Hobbit’ Skull Study Finds Hobbit Is Not Human:

In a an analysis of the size, shape and asymmetry of the cranium of Homo floresiensis, Karen Baab, Ph.D., a researcher in the Department of Anatomical Scienes at Stony Brook University, and colleagues conclude that the fossil, found in Indonesia in 2003 and known as the “Hobbit,” is not human.

New Imaging Method Lets Scientists ‘See’ Cell Molecules More Clearly:

Scientists have always wanted to take a closer look at biological systems and materials. From the magnifying glass to the electron microscope, they have developed ever-increasingly sophisticated imaging devices.

Scientists Agree Human-induced Global Warming Is Real, Survey Says:

While the harsh winter pounding many areas of North America and Europe seemingly contradicts the fact that global warming continues unabated, a new survey finds consensus among scientists about the reality of climate change and its likely cause.

First Americans Arrived As Two Separate Migrations, According To New Genetic Evidence:

The first people to arrive in America traveled as at least two separate groups to arrive in their new home at about the same time, according to new genetic evidence published online in Current Biology.

New Findings On The Evolution Of Parasitism:

Today, 150 years after Darwin’s epochal “On the Origin of Species,” many questions about the molecular basis of evolution are still waiting for answers. How are signaling pathways changed by genes and by the environment enabling the development of new species? Scientists at the Max Planck Institute for Developmental Biology in Tübingen, Germany, are striving to decode the molecular basis of parasitism. Their objects of research are nematode worms.

Humans And Mice Express The Same Olfactory Preferences:

Humans and mice are attracted by the same odors. This has been revealed for the first time by a team of French researchers in the “Neurosciences sensorielles, comportement, cognition” Unit (CNRS / Université Lyon 1).

All Earth’s Seasons Now Arrive Two Days Earlier, Researchers Report:

Not only has the average global temperature increased in the past 50 years, but the hottest day of the year has shifted nearly two days earlier, according to a new study by scientists from the University of California, Berkeley, and Harvard University.

Global Impact Of Climate Change On Biodiversity:

When three undergraduates set off on an expedition in 1965 to trap moths on Mount Kinabalu in Borneo, little did they realise that they were establishing the groundwork for a study of the impacts of climate change.

Nile Delta Fishery Grows Dramatically Thanks To Run-off Of Sewage, Fertilizers:

While many of the world’s fisheries are in serious decline, the coastal Mediterranean fishery off the Nile Delta has expanded dramatically since the 1980s.
