An international study of the impacts of 26 landfalling tropical cyclones reveals trade-offs between ecosystem resistance and resilience. The findings can help guide managers as they plan for climate change and its impacts to coastal ecosystems and eco…

Bioengineers have shown they can eradicate advanced-stage ovarian and colorectal cancer in mice in as little as six days with a treatment that could be ready for human clinical trials later this year.

Researchers have discovered that power-producing organelles in the eye’s photoreceptor cells, called mitochondria, function as microlenses that help channel light to these cells’ outer segments where it’s converted into nerve signals. The discovery in …

New research has found that people who spent more time in green spaces reported less anxiety and depression during the first year of the pandemic. Merely having abundant green space nearby, as measured by satellite images, was associated with lower dep…

Renewable energy that feeds into the main power grid could destabilize the system and potentially cause power failures according to a new study.

Promising technologies for converting wastewater into drinkable water produce a chemical compound that can be toxic, corrosive and malodorous. An analysis of one possible solution reveals ways to optimize it for maximum energy efficiency, pollutant rem…

Compared with women who enter menopause around age 50, women who experience very early menopause (before the age of 40) were found to be 35% more likely to develop some type of dementia later in life, according to a large study of women living in the U…

It may be possible to identify the presence of an aggressive brain tumor in children by studying their cerebrospinal fluid, according to new research.

A new review paper on magnetic topological materials introduces the new theoretical concept that interweave magnetism and topology.

All life evolves: microorganisms can become resistant to drugs, viruses evade our vaccines, and species may adapt to climate change. Even the ability to evolve can evolve. If we were to understand how this happens and which mechanisms play a role, it m…

Scientists have redesigned a key component of a widely used CRISPR-based gene-editing tool, called Cas9, to be thousands of times less likely to target the wrong stretch of DNA while remaining just as efficient as the original version, making it potent…

As of today, there is no vaccine against hepatitis C. To improve the search for it, researchers are looking for a so-called surrogate model: an animal that can also suffer from viral hepatitis and whose course of infection allows conclusions about the …

There is no other place where so many Neolithic pile dwellings have been uncovered as around the Alps. It is a mystery, however, how this ‘building boom’ came to be. Researchers have now uncovered new clues, and say that settlers at Lake Varese in nort…

A new study proposes a framework featuring a more holistic picture of the cybersecurity landscape, along with a model that explicitly represents multiple dimensions of the potential impacts of successful cyberattacks.

Impressive athleticism was on display during the Winter Olympics, but being at the top of one’s game doesn’t necessarily protect against digestive distress resulting from exercise. Surprisingly, some people are adding cocoa to their diets to reduce the…

Early in the pandemic, many people fastidiously disinfected surfaces because laboratory studies predicted that SARS-CoV-2 could be easily transmitted in this way. Now, researchers have found a possible explanation for why the predictions didn’t pan out…

Researchers were able to observe stress changes before and during an earthquake induced by hydraulic fracturing in Alberta, Canada, with the help of a phenomenon called seismic anisotropy.

Researchers already knew that insects are an excellent source of protein for humans, but they didn’t expect to learn that they have such a positive impact on plants. Researchers discuss the benefits of using the waste from insect-as-food-and-feed produ…

When did populations of Homo sapiens first arrive in China and what happened when they encountered the Denisovans or Neanderthals who lived there? A new study opens a window into hunter-gatherer lifestyles 40,000 years ago. Archaeological excavations a…

Black holes and neutron stars are some of the most extreme objects in the Universe, ripping up neighboring stars. But they are messy eaters and much of they take in gets flung back into space. Scientists have now observed a neutron star blasting out wa…
