Long ago, in the largest canyon system in our solar system, vibrations from “marsquakes” shook soft sediments that had accumulated in Martian lakes. The shaken sediments formed features that now appear as a series of low hills apparent in a geological map based on NASA images. The map was released today by the U.S. Geological Survey (USGS). This map of […]

A research paper published in Nature Climate Change predicts widespread death of needleleaf evergreen trees (NET) within the Southwest United States by the year 2100 under projected global warming scenarios. The research team that conducted the study, which includes University of Delaware’s Sara Rauscher, considered both field results and a range of validated regional predictions and global simulation models of […]

10 myths about global warming, and what the science really says. THE REASONS FOR raising doubts about the human causes of global warming, explains Skeptical Sciences John Cook, are often political rather than scientific. Cook hears from climate change skeptics that ‘“its all a liberal plot to spread socialism and destroy capitalism. However, what is causing global warming is a […]

The brain develops faster during early childhood and more than any other time in our life. In children, it is a magnificent thinking machine that learns and grows by interacting with the world. Not surprisingly, experts say that the foods kids eat not only fuel their bodies but their minds as well. Research shows that healthy eating can improve children’s […]

Every week, more than 50 million Americans take acetaminophen, the active ingredient in Tylenol and many other popular painkillers, to ease their aches and pains. But a new study has revealed that the drug also dulls emotions—including happiness. Prior research showed that acetaminophen can help take the sting out of negative feelings like dread, but the new findings from Ohio […]

Climate change is killing off Bees In India. A lethal combination of climate change and human interference is helping to wipe out colonies of the giant honeybees on which many plants and trees in India depend for their survival. The precise cause of colony collapse disorder (CCD) is not known, but researchers say that the loss of the bees will […]

Researchers have identified a new mechanism that drives the development of form and structure, through the observation of artificial materials that shape-shift through a wide variety of forms which are as complex as those seen in nature. It’s curious to observe such life-like behavior in a non-living thing – in many cases, artificial objects can look more ‘alive’ than living […]

UK researchers have unearthed ancient fossil forests, thought to be partly responsible for one of the most dramatic shifts in Earth’s climate in the past 400 million years. The fossil forests, with tree stumps preserved in place, were found in Svalbard, a Norwegian archipelago situated in the Arctic Ocean. They were identified and described by Dr Chris Berry of Cardiff […]

An enormous iceberg in Antarctica has killed off 150,000 penguins and threatens to wipe out an entire colony, which has become trapped and unable to reach food. A study by researchers from New Zealand and Australia said only about 10,000 Adélie penguins have survived after an iceberg – labelled B09B – grounded in a bay in 2010. The grounding, at […]

“It has happened,” said Philip Bump. For the first time in human history, atmospheric carbon dioxide levels hit a daily average of 400 parts per million (ppm) last week. “There is now more carbon dioxide in the atmosphere than at any point since 3 million years ago.” Back then, global temperatures were about 7 degrees higher, the Arctic was ice-free, […]
