As the Earth’s human population grows, greenhouse gas emissions from the world’s food system are on track to expand. A new study demonstrates that state-of-the-art agricultural technology and management can not only reduce that growth, but eliminate it altogether by generating net negative emissions — reducing more greenhouse gas than…
Remembering the order of information is central for a person when participating in conversations, planning everyday life, or undergoing an education. A new study, published in the scientific journal PLoS One, shows that this ability is probably human unique. Even the closest relatives of humans, such as bonobos, do not…
Not only does a lack of sleep make you feel awful, research has shown it impairs the brain. What’s more, sleep loss over long periods can even increase risk for Alzheimer’s and other neurological diseases. Researchers want to understand how sleep deprivation causes this harm. In a new study in…
A good night’s sleep has many proven health benefits, and a new Scripps Research study suggests one more: preventing opioid relapse. In the new study, published online in Neuropharmacologyon August 12, 2023, scientists gave an experimental insomnia treatment to rats experiencing oxycodone withdrawal. The researchers found that the animals were…
The researchers studied birds given a simulated bacterial infection in order to stimulate their immune system. The birds were then compared with birds whose immune system was not stimulated — and their activity was measured for several weeks using miniature data loggers. “We found that the birds whose immune system…
The treadmill exercise test with electrocardiogram (ECG), also known as an exercise stress test, is one of the most familiar tests in medicine.
