A new study speaks to the importance of public awareness programs in keeping residents -- and emergency management offices -- informed about rare but potentially lethal natural events in their area.
Since the Perseverance rover landed in Jezero crater on Mars in February, the rover and its team of scientists back on Earth have been hard at work exploring the floor of the crater that once held an ancient lake. Perseverance and the Mars 2020 mission are looking for signs of ancient life on Mars and preparing a returnable cache of samples for later analyses on Earth.
New research has uncovered a novel way to combine two different states of matter. For one of the first times, topological photons -- light -- has been combined with lattice vibrations, also known as phonons, to manipulate their propagation in a robust and controllable way.
Researchers have devised and tested a new, highly sensitive method of detecting and counting defects in transistors -- a matter of urgent concern to the semiconductor industry as it develops new materials for next-generation devices.
Researchers have discovered that the more severely infected with COVID-19 a mother is, the more likely she is to experience preterm birth.
Researchers have developed a versatile composite fabric that can deactivate both biological threats, such as the novel coronavirus that causes COVID-19, and chemical threats, such as those used in chemical warfare. A material that is effective against both classes of threats is rare. The new material also is reusable. It can be restored to its original state after the fabric has been exposed to...
Engineers have developed a new type of wearable with several unprecedented benefits. Not only are the devices custom 3D-printed based on body scans of wearers, but they can operate continuously using a combination of wireless power transfer and compact energy storage.
The full magnitude of the impact of smoke from seasonal fires in Central Africa - and in particular, the potential climate warming from the absorption by the black carbon component of the aerosol - is underestimated by some climate models over the South-East Atlantic, new research has shown.
As the popularity of fitness trackers has increased, so have the opportunities to use such devices to not only track fitness goals but also increase the motivation to meet those goals. Researchers are using control systems engineering tools to tailor motivational messages sent to individual device users.
A new study by UC Santa Barbara researchers speaks to the importance of public awareness programs in keeping residents—and emergency management offices—informed about rare but potentially lethal natural events in their area.
In a paper published in Advances in Food Security and Sustainability, researchers found that farmers in East Africa (Burundi, Democratic Republic of Congo (DRC), Ethiopia, Kenya, Tanzania, and Uganda) were able to better adapt to the impact of COVID-19 than those in the Southern African countries of Malawi, Zambia, and Zimbabwe.
Since the 1970s, dams have been removed from the U.S. at an increasing rate, with the aim to improve the ecology of river ecosystems, fish migration pathways, water quality, and recreation spaces.

Details are deficient, scientific analysis contentious and expert voices missing in Markson’s thesis about ‘what really happened’ in China, which establishes a crime scene around the Wuhan Institute of Virology With 4.55 million deaths from the Covid-19 pandemic so far, the hunt for its origins has turned into something akin to an inquest on a mass scale. Are we dealing essentially with a...
Over time, concrete cracks and crumbles. Well, most concrete cracks and crumbles. Structures built in ancient Rome are still standing, exhibiting remarkable durability despite conditions that would devastate modern concrete. One of these structures is the large cylindrical tomb of first-century noblewoman Caecilia Metella. New research shows that the quality of the concrete of her tomb may exceed...
Researchers have been studying seed dispersal to understand how chemicals impact interactions between fruit and the animals that eat them.
Captain Kirk may really be going to space, but he's not doing the real exploration, writes Quirks & Quarks host Bob...
Italian Giorgio Parisi, winner of the 2021 Nobel Physics Prize, slammed Friday the lack of funding for research in Italy, saying it invested one of the lowest amounts in Europe.
