2.4 Million-Year-Old DNA Is Oldest Ever Recovered
The DNA fragments collected from permafrost in northern Greenland unlock insights into an ancient ecosystem. DNA fragments recovered from an ice sheet in northern Greenland represent the oldest DNA ever found, a group of Danish scientists report today (December 7) in Nature. The team dates the samples to around 2.4 million years ago, making the DNA […]

Opioids Recruit the Immune System to Cause Withdrawal Symptoms
A study finds that T cells induced by heroin cross the blood-brain barrier to wreak havoc on the brain, hinting at new ways to prevent withdrawal. ABOVE:© ISTOCK.COM, D-KEINE Researchers have uncovered one way that opioid use seems to result in withdrawal symptoms, identifying a previously unknown pathway in the immune system that results in unstable […]

New Insight into Brain Inflammation Inspires New Hope for Epilepsy Treatment
Clinicians and researchers teamed up to investigate how inappropriate proinflammatory mechanisms contribute to the pathogenesis of drug-refractory epilepsy. Doctors treat epilepsy with anticonvulsants to control seizures, but some patients do not respond to these first-line therapies. For patients with drug-refractory epilepsy (DRE), whose seizures persist after treatment with two or more anticonvulsants, clinicians must surgically […]

Mice With a Healthy Gut Microbiome Are More Motivated to Exercise
A neural pathway between the gut and the brain led to the release of dopamine when the mice ran on a wheel or treadmill, but only in the presence of a robust microbiome. ABOVE:© ISTOCK.COM, MARY SWIFT The gut is a jungle teeming with microorganisms that are instrumental to the process of digesting food, regulating metabolism, […]

How Chlamydia Guards Itself Against the Immune System
The bacterium produces a particular protein that allows it to sneak past the human immune system even while triggering inflammation. ABOVE:© ISTOCK.COM, LUISMMOLINA EDITOR’S CHOICE IN IMMUNOLOGY Jörn Coers, an immunologist at Duke University, says the world is facing a silent pandemic: chlamydia. The US Centers for Disease Control and Prevention (CDC) estimates that 4 million people contracted […]
