Extending the life of a lithium metal anode using a protective layer made of an extremely tough gel electrolyte
- ScienceDaily
- 23/5/9 21:20
A research team has succeeded in substantially improving the cycling performance of a lithium metal battery by developing a mechanically very strong polymeric gel electrolyte and integrating it into the battery as a layer to protect the lithium metal anode. This achievement may greatly facilitate efforts to put lithium metal anodes -- a potentially very high performance anode material -- into...
Kangaroo Island ants 'play dead' to avoid predators

Basic 'toolkit' for organ development is illuminated by sea star
- ScienceDaily
- 23/5/9 18:20
One of the basic and crucial embryonic processes to unfold in virtually every living organism is the formation of hollow, tubular structures that go on to form blood vessels or a digestive tract, and through branching and differentiation, complex organs including the heart and kidneys. This study illuminates fundamental design principles of tubulogenesis for all chordates, including mammals.
Earth's first animals had particular taste in real estate
- ScienceDaily
- 23/5/9 18:20
Even without body parts that allowed for movement, new research shows -- for the first time -- that some of Earth's earliest animals managed to be picky about where they lived.
Scientists create CRISPR-based drug candidate targeting the microbiome
- ScienceDaily
- 23/5/9 18:20
A new drug candidate targeting E. coli in the gut is in phase 1 clinical trials. According to a new paper it may improve the well-being of blood cancer patients and reduce their mortality rate from E. coli infections.
Exploring the underground connections between trees
- ScienceDaily
- 23/5/9 18:20
Fungal networks interconnecting trees in a forest is a key factor that determines the nature of forests and their response to climate change. These networks have also been viewed as a means for trees to help their offspring and other tree-friends, according to the increasingly popular 'mother-tree hypothesis'. An international group of researchers re-examined the evidence for and against this...
New research sheds light on how human vision perceives scale
- ScienceDaily
- 23/5/9 18:20
Researchers have discovered new insights into how the human brain makes perceptual judgements of the external world. The study explored the computational mechanisms used by the human brain to perceive the size of objects in the world around us.
Tooth enamel provides clues to hunter-gatherer lifestyle of Neanderthals
- ScienceDaily
- 23/5/9 18:20
A study has given an intriguing glimpse of the hunting habits and diets of Neanderthals and other humans living in western Europe.
Crab populations are crashing. Could losing their sense of smell be one of the important reasons why?
- ScienceDaily
- 23/5/9 18:20
A new U of T Scarborough study finds that climate change is causing a commercially significant marine crab to lose its sense of smell, which could partially explain why their populations are thinning.
How 1,000 undergraduates helped solve an enduring mystery about the sun
- ScienceDaily
- 23/5/9 18:20
For three years at the height of the COVID-19 pandemic, a group of students spent an estimated 56,000 hours analyzing the behavior of hundreds of solar flares. Their results could help astrophysicists understand how the sun's corona reaches temperatures of millions of degrees Fahrenheit.
Best treatment for excessive daytime sleepiness
- ScienceDaily
- 23/5/9 18:20
Researchers have found that the drug solriamfetol is the most effective treatment for excessive daytime sleepiness (EDS) for people with obstructive sleep apnea (OSA).
Tuberculosis disease intensifies HIV antibody response in people with HIV
- ScienceDaily
- 23/5/9 18:20
New research found that people living with HIV that have had pulmonary tuberculosis had broader and more potent HIV antibody responses and differences in HIV sequences predicted to be antibody resistant as compared to those without suspected or documented tuberculosis.

A new study in mice and rats found that restoring certain signals in a brain region that processes smells countered depression.
Evidence of Ice Age human migrations from China to the Americas and Japan
- ScienceDaily
- 23/5/9 18:20
Scientists have used mitochondrial DNA to trace a female lineage from northern coastal China to the Americas. By integrating contemporary and ancient mitochondrial DNA, the team found evidence of at least two migrations: one during the last ice age, and one during the subsequent melting period. Around the same time as the second migration, another branch of the same lineage migrated to Japan,...
Extracting the best flavor from coffee
- ScienceDaily
- 23/5/9 18:20
Researchers explore the role of uneven coffee extraction using a simple mathematical model. They split the coffee into two regions to examine whether uneven flow does in fact make weaker espresso. One of the regions in the model system hosted more tightly packed coffee than the other, which caused an initial disparity in flow resistance. The extraction of coffee decreased the flow resistance...
Viruses could reshuffle the carbon cycle in a warming world
- ScienceDaily
- 23/5/9 01:06
The roles microbes play in ecosystems are changing with global warming. Microbes are also affected by infection by viruses, but scientists know relatively little about how these viral infections could change how microbes react to warming. In this study, scientists describe different ways that increasing temperatures could affect viruses and their microbial hosts. Their preliminary models show that...
