How salt from the Caribbean affects our climate

Past cold periods such as the Little Ice Age were associated with reduced strength of North Atlantic currents and increased surface salinity in the Caribbean. This was accompanied by disturbances in the distribution of salt to the north leading to longer, stronger cooling phases in the northern hemisphere.

Some benefits of exercise stem from the immune system

Research in mice shows that the anti-inflammatory properties of exercise may arise from immune cells mobilized to counter exercise-induced inflammation. Immune cells prevent muscle damage by lowering levels of interferon, a key driver of chronic inflammation, inflammatory diseases, and aging.

Don’t worry, be happy. We live in a golden age of astronomy

Our species has been around on the planet for approximately 200,000 years. That’s some 8,000 generations, quite a long while any way you slice it. And certainly our ancestors occasionally glanced up at a starry night sky, unhindered by light pollution, and wondered what the twinkling lights were all about. But the history of astronomyContinue reading "Don’t worry, be happy. We live in a golden...

Seeing the unseen: How butterflies can help scientists detect cancer

There are many creatures on our planet with more advanced senses than humans. Turtles can sense Earth's magnetic field. Mantis shrimp can detect polarized light. Elephants can hear much lower frequencies than humans can. Butterflies can perceive a broader range of colors, including ultraviolet (UV) light.

Scientists map loss of groundwater storage around the world

Global water resources are stretched by climate change and human population growth, and farms and cities are increasingly turning to groundwater to fill their needs. Unfortunately, the pumping of groundwater can cause the ground surface above to sink, as the aquifers below are drained and the architecture of the ground collapses. A new study maps this loss of groundwater storage capacity around...

Photo battery achieves competitive voltage

Researchers have developed a monolithically integrated photo battery using organic materials. The photo battery achieves an unprecedented high discharge potential of 3.6 volts. The system is capable of powering miniature devices.

Charged 'molecular beasts' the basis for new compounds

Mass spectrometers are high-tech machines that play an important role in our society. They are highly sensitive analytical instruments that are indispensable in areas such as medical diagnostics, food quality control and the detection of hazardous chemical substances. A research group is working to modify mass spectrometers so that they can be used for a completely different purpose: the chemical...

An exotic tick that can kill cattle is spreading across Ohio

A species of exotic tick arrived in Ohio in 2021 in such huge numbers that their feeding frenzy on a southeastern farm left three cattle dead of what researchers believe was severe blood loss. The scientists have reported on the state's first known established population of Asian longhorned ticks, and are now conducting research focused on monitoring and managing these pests.
