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…
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…
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…
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.
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.

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 …
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…
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…
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 …
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…
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.
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 …
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.
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…
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 …
Images from the Perseverance rover confirm that Jezero crater is an ancient Martian lake, MIT researchers report. The team also detected signs of flash flooding strong enough to carry large boulders downstream into the ancient delta.
Researchers have found that a drug first developed to treat Alzheimer’s disease, schizophrenia and sickle cell disease reduces obesity and fatty liver in mice and improves their heart function — without changes in food intake or daily activity.
In urban areas across the U.S., low-income neighborhoods and communities of color experience an average of 28% more nitrogen dioxide (NO2) pollution than higher-income and majority-white neighborhoods. The disparity is driven primarily by proximity to …
Researchers analyzed the accumulated data from the Atacama Large Millimeter/submillimeter Array (ALMA) and depicted the motion of a young twin star system XZ Tauri over three years. This ‘ALMA Animation’ of twin stars sheds new light on the origins of …
