For many couples, COVID-19 quarantine has shattered the normal routine and led some to renegotiate who does what around the house. Research has shown that the way couples divide up housework and how they feel about their arrangements are related to relationship satisfaction. It's also known that communication plays a big role in relationship satisfaction.
Oxygen first accumulated in the Earth's atmosphere about 2.4 billion years ago, during the Great Oxidation Event. A long-standing puzzle has been that geologic clues suggest early bacteria were photosynthesizing and pumping out oxygen hundreds of millions of years before then. Where was it all going?

Bothell, Wash.-based Tethers Unlimited says it will provide key communications and propulsion capabilities to Southwest Research Institute in support of a NASA mission to study how the sun's corona whips up the solar wind. Tethers Unlimited's SWIFT-XTS software-defined radio will be used for telemetry and control of the four suitcase-sized microsatellites that will conduct a mission known...
In May a single study published in one of the world’s leading medical journals led to trials of a possible coronavirus treatment being halted around the world. Weeks later the study was retracted and the company behind the data used is facing serious scrutiny. Melissa Davey tells us how it all unravelledYou can read Melissa Davey’s feature on how unreliable data in Covid-19 research was...
In a paper published by the Behavioral Sciences & Law journal, experts from the University of Surrey take a critical look at the growing use of algorithmic risk assessment tools, which act as a form of expert scientific evidence in a growing number of criminal cases.
Researchers at Linköping University, Sweden, are attempting to convert carbon dioxide, a greenhouse gas, to fuel using energy from sunlight. Recent results have shown that it is possible to use their technique to selectively produce methane, carbon monoxide or formic acid from carbon dioxide and water. The study has been published in ACS Nano.
Doctors could soon be administering an entire course of treatment for life-threatening conditions with a 3-D printed capsule controlled by magnetic fields thanks to advances made by University of Sussex researchers.
Citrus greening disease (Huanglongbing of HLB), transmitted by the Asian citrus psyllid, is currently the biggest threat to the citrus industry and is threat to many parts of the world, including Asia, Africa, South America, and the Unites States. In Florida alone, citrus greening disease has accounted for losses of several billions of U.S. dollars.
Princeton University researchers may have solved a long-standing mystery in conservation that could influence how natural lands are designated for the preservation of endangered species.
The physical and chemical properties of intermetallic compounds are governed by the real structure of synthesized materials and are strongly influenced by the structural imperfections, e.g. strain, dislocations, and presence of admixture phases. This leads to inconsistent reports for known and extensively studied materials.
China has removed pangolin parts from its official list of traditional medicines, state media reported Tuesday, days after increasing legal protections on the endangered animal.
The first Arab space mission to Mars, armed with probes to study the Red Planet's atmosphere, is designed to inspire the region's youth and pave the way for scientific breakthroughs, officials said Tuesday.
Researchers have developed a model that can estimate regional disease burden and the impact of vaccination, even in the absence of robust surveillance data, a new study reveals.
Researchers may have solved the long-standing puzzle of why migratory shorebirds around the world are plummeting several times faster than coastal ecosystems are being developed. They discovered that shorebirds overwhelmingly rely on tidal zones closest to dry land, which are most often lost to development. The findings suggest that protecting species requires a detailed understanding of how...
Virologists have identified detailed methods of how to perform research on SARS-CoV-2, the virus that causes COVID-19, including procedures that effectively inactivate the virus to enable safe study of infected cells.
Soft robots and biomedical implants that reconfigure themselves upon demand are closer to reality with a method to print shapeshifting materials.
To test the James Webb Space Telescope's readiness for its journey in space, technicians successfully commanded it to deploy and extend a critical part of the observatory known as the Deployable Tower Assembly.
