Researchers have discovered a way to stimulate neurons deep within the brain without the invasive, implanted electrodes that physicians currently use to treat severe brain-related conditions like Parkinson's disease.

Current limitations: Implanted electrodes stimulate neurons in just one part of the brain and aren't helpful for other conditions (like stroke, traumatic brain injury or memory loss from Alzheimer's) that might benefit from much wider deep-brain stimulation that doesn't cause lasting damage to surrounding brain tissue.

What they did: Researchers from MIT sent two high-frequency electrical signals, which pass through the brain without exciting many neurons, from opposite sides of the brain in mice. They met in the middle, creating a new type of electrical wave that stimulated the neurons in a deep region of the brain.

Why it matters: Current non-invasive methods aren't able to work deep in the brain, which is where efforts to repair damage to neurons are most needed.

Large coronavirus outbreaks leading to high death rates

Data: The COVID Tracking Project; Chart: Sara Wise/Axios

Many of the states where coronavirus cases have recently skyrocketed are also seeing the highest death rates in the nation, a painful reminder that wherever the virus goes, death eventually follows.

Between the lines: Deaths usually lag behind cases by a few weeks. Given America's record-high case counts, it's reasonable to expect that death rates across the country will continue to rise in tandem.

Pandemic scrambles Americans' acceptance of science

The pandemic is throwing a wrench into Americans' understanding of science, which has big implications for climate change.

Driving the news: Recent focus groups in battleground states suggest some voters are more skeptical of scientists in the wake of the coronavirus pandemic, while surveys reveal the persistence of a deep partisan divide.
