Microbiology research furthers understanding of ocean’s role in carbon cycling
Microbiology researchers have shed new light on the mechanisms of carbon cycling in the ocean, using a novel approach to track which microbes are consuming different types of organic carbon produced by common phytoplankton species.
Planned home birth presents little risk where midwifery is well-integrated
In the state of Washington, a planned home birth with a licensed midwife is just as safe as a birth at a licensed birth center. Researchers arrived at this conclusion after analyzing outcomes of more than 10,000 community births in Washington state bet…
Sweet corn yield gain over 80 years leaves room for improvement
New research shows sweet corn, when planted at high densities, has steadily increased in yield since the 1930s. The historical view underscores the importance of planting modern density-tolerant hybrids at their optimal densities, and suggests an oppor…
Elastic polymer that is both stiff and tough, resolves long-standing quandary
A conundrum has long stumped polymer scientists: Elastic polymers can be stiff, or they can be tough, but they can’t be both. This stiffness-toughness conflict is a challenge for scientists developing polymers that could be used in applications includi…
Environmentally friendly ways to cool homes
The summer of 2021 in Western Canada was one of the hottest on record. In the Canadian province of British Columbia alone, 59 weather stations registered their hottest temperatures ever on June 27. For those lucky enough to have air conditioners, keepi…
Lung maintains long-term memory of COVID infection
After infection with the COVID virus, where does the immune system store the memory? A new study finds memory cells take up residence in the lung to protect against reinfection.
Refuting a 70-year approach to predicting material microstructure
Researchers have developed a new microscopy technique that maps material microstructure in three dimensions; results demonstrate that the conventional method for predicting materials’ properties under high temperature is ineffective.

‘Gut bugs’ can drive prostate cancer growth and treatment resistance
Common gut bacteria can become ‘hormone factories’ – fuelling prostate cancer and making it resistant to treatment, a new study shows. Scientists revealed how gut bacteria contribute to the progression of advanced prostate cancers and their resistance …
Climate change literacy lessons from Africa
Addressing the climate crisis will require cooperation on a massive scale, but to accomplish this, people need to know what specific challenges lie ahead and how to best move forward. Across the globe, people are facing the effects of the climate crisi…
The climate-driven mass extinction no one had seen
Two thirds of all mammals vanished from Africa and the Arabian Peninsula around 30 million years ago, when the climate on Earth changed from swampy to icy. But we are only finding out about this mass extinction now. Researchers examined hundreds of fos…
Non-English-language science could help save biodiversity
It is commonly assumed that any important scientific knowledge would be available in English, and so scientific knowledge used in international studies is predominantly sourced from English-language documents. But is this assumption correct? According …
Climate change tipping points: back to the drawing board
We regularly hear warnings that climate change may lead to ‘tipping points’: irreversible situations where savanna can quickly change into desert, or the warm gulf stream current can simply stop flowing. But the earth is much more resilient than previo…
Ten millennia of hepatitis B virus evolution described
Researchers uncover the evolution of the hepatitis B virus since the Early Holocene by analyzing the largest dataset of ancient viral genomes produced to date.
Scientists assemble a biological clock in a test tube to study how it works
Daily cycles in virtually every aspect of our physiology are driven by biological clocks (also called circadian clocks) in our cells. The cyclical interactions of clock proteins keep the biological rhythms of life in tune with the daily cycle of night …
Promising results for Parkinson’s disease treatment
Researchers have found a way to make deep brain stimulation (DBS) more precise, resulting in therapeutic effects that outlast what is currently available. The work will significantly advance the study of Parkinson’s disease.
Chang’e-5 samples reveal key age of moon rocks
A lunar probe launched by the Chinese space agency recently brought back the first fresh samples of rock and debris from the moon in more than 40 years. Now an international team of scientists has determined the age of these moon rocks at close to 1.97…
How mussels make a powerful underwater glue
Blue mussels (Mytilus edulis) spend their days being buffeted by crashing waves. They manage to stay tethered to the rocks or their fellow mussels thanks to a highly effective underwater glue they produce. Because achieving adhesion in the presence of …
