COLUMBUS, Ohio – Researchers who are working to fix global positioning system (GPS) errors have devised software to take a more accurate measurement of altitude – particularly in mountainous areas. (more…)
An international team of researchers, including physical oceanographers from the Woods Hole Oceanographic Institution (WHOI), has confirmed the presence of a deep-reaching ocean circulation system off Iceland that could significantly influence the ocean’s response to climate change in previously unforeseen ways.
The current, called the North Icelandic Jet (NIJ), contributes to a key component of the Atlantic Meridional Overturning Circulation (AMOC), also known as the “great ocean conveyor belt,” which is critically important for regulating Earth’s climate. As part of the planet’s reciprocal relationship between ocean circulation and climate, this conveyor belt transports warm surface water to high latitudes where the water warms the air, then cools, sinks, and returns towards the equator as a deep flow.

*Drought simulator will enable in-depth testing under real-world conditions*
COLUMBIA, Mo. – Historically, droughts have had devastating effects on agriculture, causing famine and increasing consumer food costs. Now, researchers at the University of Missouri College of Agriculture, Food and Natural Resources (CAFNR) have completed two drought simulators designed to test the effects of water deficiency on crops. The simulators are located at the University of Missouri’s Bradford Research and Extension Center east of Columbia.
The simulators, part of a $1.5 million Missouri Life Sciences Research Board grant, are essentially mobile greenhouses measuring 50 feet by 100 feet. To simulate drought, researchers move the greenhouses over plants when it is raining and move them away from plants when it is sunny. A test plot of the same plants will be kept next to the simulator to provide a comparison. The drought simulators will increase the real-world application of scientific research, as they allow researchers to more closely mimic actual drought conditions. (more…)
COLUMBUS, Ohio – Think about how much you fight and argue with your spouse today. A new study suggests that your current level of conflict probably won’t change much for the remainder of your marriage.
That may be good news for the 16 percent of couples who report little conflict or even the 60 percent who have only moderate levels of conflict. But it’s not such happy news for the 22 percent of couples who say they fight and argue with each other a lot.
The study followed nearly 1,000 couples over 20 years, from 1980 to 2000. (more…)
An international team of astronomers led by a former UA graduate student has set out on the largest program to date exploring the alien atmospheres of “Hot Jupiters” – massive planets in solar systems far away from our own. (more…)
COLUMBUS, Ohio – A new study uses – for the first time – recorded jailhouse telephone conversations between men charged with felony domestic violence and their victims to help reveal why some victims decide not to follow through on the charges.
Researchers listened to telephone conversations between 17 accused male abusers in a Washington state detention facility and their female victims, all of whom decided to withdraw their accusations of abuse. For each of the couples, the researchers analyzed up to about three hours of phone conversations. (more…)
*A former UA postdoctoral fellow has discovered amazing relationships between organisms: a bacterium living inside a bacterium living inside an insect. Evolving together, the organisms depend on each other for survival, and each contributes a subset of the enzymes needed in shared metabolic pathways.*
Sure, many bacteria cause disease, but most people don’t realize how beneficial they can be. The human gut, for example, brims with bacteria that play critical roles in everything from immune system development and extracting energy from food to providing necessary nutrients.
They get a nice comfy home living inside people, and in return they help us. It’s a symbiotic relationship. However, these beneficial partnerships are nothing compared to the complex relationships between bacteria and citrus mealybugs recently discovered by a team of biologists led by former UA researcher John McCutcheon, who recently took a position as an assistant professor at the University of Montana.
