At a Senate hearing on Wednesday, Robert F. Kennedy, Jr., referred to ibogaine as the most promising treatment for PTSD and depression “that anybody’s ever seen.” Does the science hold that up?
The U.S. Food and Drug Administration is seeking to accelerate the review process for three companies that are studying psilocybin and an MDMA-like drug as treatments for depression and PTSD
Measurements of this interstellar comet’s molecular makeup show an excess of heavy water molecules that is dramatically different from anything known to have ever formed around our sun
Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) can have the same genetic cause, a discovery that won two neurogeneticists a portion of the 2026 Breakthrough Prize in Life Sciences
The states with the greatest increases in 988 crisis hotline use since 2022 experienced the greatest decrease in suicide mortality, but the hotline alone may not explain the drop
New research reveals that a rift in Earth’s crust is just a few million years away from splitting the continent of Africa into two—and creating a new ocean
When an earthquake rupturing along a fault hits a barrier, it creates a seismic signature called the “stopping phase.” Scientists have isolated this and could use it to better predict earthquake risk
Heavy smoke emanated from wildland fires in Georgia as the NOAA-21 satellite passed over on April 21, 2026. In this view combining datasets from the Visible Infrared Imaging Radiometer Suite (VIIRS), a true-color corrected reflectance image is overlaid with the fires and thermal anomalies layers.
This false-color corrected reflectance image (bands M11-I2-I1) reveals the active fire fronts of the two fires, shown in a vibrant red. The fire on the left is the Pineland Road Fire, while the Highway 82 fire in on the right. According to government and media accounts, both fires had the potential to threaten railroad infrastructure and other structures, and some evacuations and road closures were in effect. Low humidity, extreme drought, and strong winds exacerbated the spread of the fires.
Press the Play button in the lower left corner to view the movement of the smoke plumes from 9 a.m. to 6 p.m. EDT on April 21, 2026.
The data come from the Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument. TEMPO measures sunlight reflected and scattered off the Earth’s surface, clouds, and atmosphere. Various gases absorb sunlight, and the resulting spectra are then used to determine the amounts of those gases in the Earth’s atmosphere.
In this view, we see concentrations of nitrogen dioxide, which is primarily produced by the burning of fossil fuels for transportation, power generation, and industrial activity, but also from wildland fires. Nitrogen dioxide is itself a toxic gas that plays an important role in the formation of ground-level ozone and particulate matter pollution. These pollutants are harmful to both human and ecosystem health.
