The suspension of fertility treatments due to the COVID-19 pandemic has had a variety of psychological impacts on women whose treatments were cancelled, but there are several protective factors that can be fostered to help in the future, according to a new study.
New type of superconductor identified
- ScienceDaily
- 20/9/21 23:05
Until now, the history of superconducting materials has been a tale of two types: s-wave and d-wave. Now, researchers have discovered a possible third type: g-wave.
Marine sponges inspire the next generation of skyscrapers and bridges

- 20/9/21 23:04
Researchers are using the glassy skeletons of marine sponges as inspiration for the next generation of stronger and taller buildings, longer bridges, and lighter spacecraft. The researchers showed that the diagonally-reinforced square lattice-like skeletal structure of Euplectella aspergillum, a deep-water marine sponge, has a higher strength-to-weight ratio than the traditional lattice designs...

- 20/9/21 23:04
It is well understood that mortality rates increase with age. Whether you live in Tokyo, rural Tennessee or the forests of Papua, New Guinea, the older you are, the more likely you are to succumb to any number of different ailments.
Nanoparticle SARS-CoV-2 model may speed drug discovery for COVID-19
- ScienceDaily
- 20/9/21 23:04
Scientists have developed a new tool that mimics how the virus that causes COVID-19 infects a cell, potentially speeding the search for treatments against the disease. The tool is a fluorescent nanoparticle probe that uses the spike protein on the virus surface to bind to cells and trigger the process that pulls the virus into cells. The probe could be used to rapidly gauge how drugs and compounds...
Think you have chemical intolerance? Answer three questions
- ScienceDaily
- 20/9/21 23:03
To increase screening of chemical intolerance, researchers have developed and validated a three-question survey that can be incorporated into patient visits within a minute.
Two Missouri crayfish species may be listed as 'threatened' under Endangered Species Act
The U.S. Fish and Wildlife Service has proposed listing two kinds of Missouri crayfish as threatened under the Endangered Species Act, as well as identifying "critical habitat" for their survival and recovery in the state's southeast watersheds.
Arctic ice melt doesn't boost sea levels, so do we care?
US government scientists reported Monday that the Arctic Ocean's floating ice cover has shrivelled to its second lowest extent since satellite records began in 1979.
E. coli bacteria offer path to improving photosynthesis
Cornell University scientists have engineered a key plant enzyme and introduced it in Escherichia coli bacteria in order to create an optimal experimental environment for studying how to speed up photosynthesis, a holy grail for improving crop yields.

40 percent of O'ahu, Hawai'i beaches could be lost by mid-century
The reactive and piecemeal approach historically used to manage beaches in Hawai'i has failed to protect them. If policies are not changed, as much as 40% of all beaches on O'ahu, Hawai'i could be lost before mid-century, according to a new study by researchers in the Coastal Geology Group at the University of Hawai'i (UH) at Mānoa School of Ocean and Earth Science and Technology (SOEST).
Why COVID-19 misinformation spread faster than pandemic in early March
In early March, when the true scope of the coronavirus pandemic was still widely unknown to the public, misinformation was rampant on social media such as Facebook and Twitter.
Researchers identify new type of superconductor
Until now, the history of superconducting materials has been a tale of two types: s-wave and d-wave.
Everglades restoration to 'get the water right' estimated at $7.4 billion through 2030
Everglades restoration projects will require about $7.4 billion over the next 10 years, compared with $6 billion spent through 2019, the U.S. Army Corps of Engineers said while presenting a draft of its work schedule.
Marine sponges inspire the next generation of skyscrapers and bridges
When we think about sponges, we tend to think of something soft and squishy. But researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) are using the glassy skeletons of marine sponges as inspiration for the next generation of stronger and taller buildings, longer bridges, and lighter spacecraft.
Southern hemisphere could see up to 30% less rain at end of the century
Projections based on climate models for the mid-Pliocene Warm Period (about 3 million years ago) suggest that countries in the tropical and subtropical southern hemisphere, including Brazil, may face longer droughts in the future. Annual rainfall may decrease as much as 30% compared with current levels.
New research shows international support for simple climate policy funding plans
For decades, scientists have urged policymakers to take prompt action to address climate change, but their calls have largely gone unanswered. Now, as wildfires ravage the west and hurricanes batter the Atlantic and Gulf coasts with greater intensity, a new study involving Washington University in St. Louis researchers finds consumers across the United States and in some European countries are...
Donald Trump’s Campaign Crafted a Careful Climate Message. Trump Ignored It
For months, the Trump campaign’s public statements and the President’s prepared remarks have repeated a message on climate change carefully calibrated not to alienate Republicans worried about the health of the planet: regardless of the science, Democratic plans to address the issue are too expensive. Last week, President Trump disregarded his own campaign’s meticulous...
