A new paper revealed that human activities are making Earth's air, soil and freshwater saltier, which could pose an 'existential threat' if current trends continue. Geologic and hydrologic processes bring salts to Earth's surface over time, but human activities such as mining and land development are rapidly accelerating this natural 'salt cycle.' Read more ›

Deforestation in the Amazon causes land surfaces up to 100 kilometers away to get warmer, suggests a new study.  The research suggests that tropical forests play a critical role in cooling the land surface -- and that effect can play out over considerable distances. Read more ›

Brazil's rapid expansion of soy production has meant an associated rise in pesticide use. Researchers found a statistically significant correlation between soy expansion and acute lymphoblastic leukemia (ALL) deaths in children between 2008 and 2019, representing the first population-wide analysis of the association between indirect exposure to agricultural pesticides and cancer.

NASA's James Webb Space Telescope has gazed at the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. Since the recording of this energetic event in 1054 CE by 11th-century astronomers, the Crab Nebula has continued to draw attention and additional study as scientists seek to understand the conditions, behavior, and after-effects of supernovae through thorough study of the Crab, a relatively nearby example.

Examining how human culture evolves in response to a changing environment may help with creating more effective climate change adaptation efforts. Using farming data from across the U.S., a team of researchers conducted a new study of cultural adaptation to climate change. They found that in many places in the U.S. farmers are already adapting to climate change by selecting crops that grow better in new conditions. Focusing on the... Read more ›

Researchers have developed a device that can detect the presence of specific molecules in a sample every 20 nanoseconds, or billionths of a second. With this new capability, researchers can potentially use frequency combs to better understand the split-second intermediate steps in fast-moving processes ranging from the workings of hypersonic jet engines to the chemical reactions between enzymes that regulate cell growth.

New studies support the idea that the brain uses a process similar to a machine-learning approach known as 'self-supervised learning.' This type of machine learning allows computational models to learn about visual scenes based solely on the similarities and differences between them, with no labels or other information. Read more ›

The first widescale assessment of methylmercury in adult amphibians in the U.S. to date shows that, in amphibians, this toxic compound is common, widespread and, at least for some, can reach very high levels. Read more ›

As technology continues to advance, the likelihood of malevolent attacks and subsequent failures on society's critical infrastructures increases. Blackouts, water shortages, transport collapses -- these potential threats to cities not only come with a hefty price tag but are likely to cause chaos and affect the health and safety of communities. UBC Okanagan Postdoctoral Research Fellow Dr. Amin Ahmadi Digehsara, along with Assistant Professor Dr. Amir Ardestani-Jaafari, both with the... Read more ›

Researchers have found that languages around the world have words for 'this' and 'that'. The 45-strong international team studied 29 languages from around the world including English, Spanish, Norwegian, Japanese, Mandarin, Tzeltal and Telugu. They wanted to see how more than 1,000 speakers use demonstratives -- words that show where something is in relation to a person talking such as 'this cat' or 'that dog'. Read more ›

The nutrients available from seafood could drop by 30 per cent for low-income countries by the end of the century due to climate change, suggests new research. That's in a high carbon emissions and low mitigation scenario, according to the study. This could be reduced to a roughly 10 per cent decline if the world were to meet the Paris Agreement targets of limiting global warming to 1.5 to 2... Read more ›

Researchers have discovered mechanisms by which specific cells are activated in alcohol withdrawal-induced headache. The research may benefit further studies of various substance use disorder mechanisms including withdrawal. It may be possible to develop a small-molecule drug therapy to inhibit interactions, resulting in fewer pain signals during alcohol withdrawal. Read more ›

As little as 1 per cent reduction in deep sleep per year for people over 60 years of age translates into a 27 per cent increased risk of dementia, according to a study which suggests that enhancing or maintaining deep sleep, also known as slow wave sleep, in older years could stave off dementia.
