Dissolvable painkillers might bring rapid relief, but researchers are warning many of them also come with a hidden and hearty dose of salt. For each half a gram of paracetamol, or acetaminophen, that comes in a dissolvable tablet, you may also swallow around 0.4 grams of sodium, one of the main components of salt. … Read more
A new collision-warning system could help satellite operators sleep a little easier. The prototype system, developed by the U.S. National Oceanic and Atmospheric Administration (NOAA), is designed to alert operators when their spacecraft may be on a collision course with another object. That’s a real and growing concern, given how crowded Earth orbit is becoming. … Read more
In the Mediterranean region, the soil is degrading, and land is turning to desert faster than anywhere else in the European Union, according to a new analysis. Experts warn that the combined effects of unsustainable land practices and climate change have depleted a finite resource to a critical point. A recent publication by a … Read more
Flowering plants in the Antarctic region are rapidly expanding, scientists say, indicating the continuing effects of climate change on the continent. The findings suggest we may have reached a tipping point in this fragile, remote ecosystem. A new study of this plant expansion looked at the two flowering plants native to Antarctica, Deschampsia antarctica … Read more
As SARS-CoV-2, the coronavirus that causes COVID-19, has spread throughout the world, many observers have failed to take note of the millions of illnesses and deaths caused by HIV—another virus that has approached pandemic status during its history. Now an HIV variant that is more virulent and transmissible has been discovered in the Netherlands, where … Read more
Last year in August, a surprise tsunami in the South Atlantic Ocean mushroomed to distances over 10,000 kilometers (more than 6,000 miles) away, rippling through the North Atlantic, the Pacific, and the Indian Oceans. It was the first time a tsunami had been recorded in three different oceans since the 2004 Indian Ocean earthquake, … Read more
Editor’s Note (1/18/22): On January 15 the eruption of a volcano near Tonga triggered a far-ranging tsunami. This story about detecting tsunamis created by earthquakes is being republished in light of this event. Buoys operate as today’s state-of-the-art tsunami-detection system. Seismic data can tell officials that an underwater earthquake has occurred, but strategically placed floating … Read more
The movement of seawater in a tsunami generates a magnetic field that travels ahead of changes in sea level, which could help us predict and prepare for it Earth 24 December 2021 By Leah Crane The aftermath of a 2010 tsunami in Chile, which was analysed in the new study International Federation of Red Cross … Read more
Seconds count when it comes to tsunami alerts, and scientists may have found a warning sign that can be detected even earlier than sea level rises: the magnetic fields created by these gigantic rushes of waves. Even though the difference might only be a minute or two, that can save lives. Magnetic field data … Read more
In the search for “potentially-habitable” extrasolar planets, one of the main things scientists look at is stellar activity. Whereas stars like our own, a G-type (G2V) yellow dwarf, are considered stable over time, other classes are variable and prone to flare-ups – particularly M-type red dwarf stars. Even if a star has multiple planets … Read more
