Worried about the environmental damage done by growing consumption of personal protective equipment (PPE) during the pandemic, the federal government is asking the private sector to come up with PPE products that won't end up in...
Researchers found that bacteria essential to ripening cheese can sense and respond to compounds produced by fungi in the rind and released into the air, enhancing the growth of some species of bacteria over others. The make-up of the cheese microbiome is critical to flavor and quality of the cheese.
Thin tissue grafts and flexible electronics have a host of applications for wound healing, regenerative medicine and biosensing. A new device inspired by an octopus's sucker rapidly transfers delicate tissue or electronic sheets to the patient, overcoming a key barrier to clinical application.
Inhibiting the SARS-CoV-2-PLpro enzyme is a novel avenue to explore in rational design of COVID-19 drugs, according to new research.
A new study is set to change international treatment recommendations for people who are newly diagnosed with HIV -- an update that could affect nearly two million people per year worldwide.
The fossilized remains of ancient deep-sea corals may act as time machines providing new insights into the effect the ocean has on rising CO2 levels.
Engineers are always looking for materials with very specific properties for their projects. Unfortunately, there are way too many options for researchers to simply guess-and-check until they find what they're looking for. Even if they were to simulate materials, instead of testing them in the lab, it would take far too long to find a suitable material.
Researchers at Tufts University have found that those distinctly funky smells from cheese are one way that fungi communicate with bacteria, and what they are saying has a lot to do with the delicious variety of flavors that cheese has to offer. The research team found that common bacteria essential to ripening cheese can sense and respond to compounds produced by fungi in the rind and released...
According to current estimates, the amount of data produced by humans and machines is rising at an exponential rate, with the digital universe doubling in size every two years. Very likely, the magnetic and optical data-storage systems at our disposal won't be able to archive this fast-growing volume of digital 1s and 0s anymore at some point. Plus, they cannot safely store data for more than a...
The news: When Twitter banned, and then unbanned, links to a questionably sourced New York Post article about Joe Biden’s son Hunter, its stated intention was to prevent people from spreading harmful false material as America heads into the final stretch of the election campaign. But thanks to the cycle of misinformation—and claims from conservatives that social-media platforms are...
In a blow to one of the few drugs being used to treat COVID-19, the World Health Organization (WHO) said interim trial results suggest that Gilead's remdesivir was no better than a placebo at limiting severely ill patients' need for mechanical ventilation, the length of their hospital stay, or their risk of death. Then, the authors looked at data on nearly 740,000 COVID-19 patients and examined...
In a new study, geneticists looked at how female moles evolved intersexual traits in order to dig and fight like the...
The SARS-CoV-2 virus may 'giving you pain relief — a gift if you will — at a high...
The space station has two oxygen-supply systems, so for now, crew members are safe, according to...
The Southern Ocean played a critical role in the rapid atmospheric carbon dioxide increase during the last deglaciation that took place 20,000 to 10,000 years ago, according to a new report by Boston College geochemist Xingchen (Tony) Wang and an international team in the online edition of Science Advances.
Unhealthy behaviours trigger moral judgments that are similar to the basic emotions that contribute to our ability to survive. Two different hypotheses are to be found in the current scientific literature as to the identity of these emotions. After developing a new approach to brain imaging, a research team shows that unhealthy behaviors trigger brain responses that are similar to those prompted...
A system developed by chemical engineers could provide a way of continuously removing carbon dioxide from a stream of waste gases, or even from the air. The key component is an electrochemically assisted membrane whose permeability to gas can be switched on and off at will, using no moving parts and relatively little energy.
Fast and reliable internet access is fundamental for research and development activity around the world. Seamless connectivity is a privilege we often take for granted. But in developing nations, technological limitations can become stumbling blocks to efficient communication and cause significant disadvantages.
Umurangi Generation is one of five games featured at this year's Night of the Indigenous Devs at the imagineNATIVE Film + Media Arts...
Sea floor sediments of the Arctic Ocean can reveal how permafrost responds to climate warming. Researchers have found evidence of past permafrost thawing during climate warming events at the end of the last ice age. Their findings caution about what could happen in the near future: Arctic warming by only a few degrees Celsius may trigger massive permafrost thawing, coastal erosion, and the release...
Physicists surprised to find that in specially coated tubes, the more viscous a liquid is, the faster it flows.
People with multiple sclerosis (MS) gradually develop increasing functional impairment. Researchers have now found a possible explanation for the progressive course of the disease in mice and how it can be reversed. The study can prove valuable to future treatments.
With antibiotic-resistant superbugs on the rise, this research shows a new way that cells are using to protect themselves - using fats as a covert weapon, and giving us new insights into alternative ways to fight infection.
A pioneering technique which captures precisely how mountains bend to the will of raindrops has helped solve a long-standing scientific enigma.
Researchers have identified three existing drugs with the potential to clear SARS-CoV-2 infections.
Two dentists debunk 14 of the most common myths about teeth. They discuss cavities, electric toothbrushes, charcoal toothpaste, and...

Droplets of fat inside our cells are helping the body's own defence system fight back against infection, University of Queensland researchers have discovered.
