Vocal fry has a bad reputation in American English. A subtype of creaky voice, a feature of speech that sounds gravelly and pulse-like, this manner of speech is sometimes used to form judgment about the speaker. In many languages, the creaky tone changes the meaning of words,

A challenge among three housemates to identify species around their inner-Brisbane home has resulted in an academic research paper, showcasing the rich biodiversity in urban landscapes.
Most ornamental crops can be classified as long-day, short-day, or day-neutral plants based on their flowering responses to the photoperiod (which is the day length), or the skotoperiod (which is the night length). Chrysanthemum is a common ornamental crop with an obligate
Avian supergene study explores the evolutionary paradox behind the unusual mating strategies of the ruff
In the colorful world of avian courtship, the ruff (Calidris pugnax) is in a league of its own. Breeding in marshes and wet meadows across Eurasia, the males of this medium-sized sandpiper species are well-known for their distinctive mating strategies, which range from
Environmental engineers suggest that anaerobic digestion could be used to clean cattle manure, produce fuel
Chemicals—from antibiotics used to keep livestock healthy to pesticides that shield crops from insects and other pests—play an important role in modern agriculture. However, many of these substances accumulate in cow manure used as fertilizer, where they contaminate crops,
The EU countries have decided that the EU is to be climate neutral by 2050. By 2030, greenhouse gas emissions must have been reduced by at least 55% compared to 1990. To meet this target, continued vigorous efforts are needed to reduce emissions, but that alone will not be
A team of researchers has reviewed a unique method for reforming the structures of ultra-small nanomaterials. These nanomaterials, called metal nanoclusters, bridge the gap between the metal atom and the bulk metal, making them highly useful in both basic and applied research.
Stir-frying yields more than just tasty dishes like Kung Pao chicken and Hunan beef. It also emits an invisible mixture of gases and particles that pollute indoor air and can be detrimental to human health. Correctly estimating such cooking emissions in a variety of settings is
Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. New research combines geology and genetics, showing how changes in the early Earth prompted a shift in how animals eat.
Hydrogen sulfide, recognized by its characteristic rotten egg smell, is synthesized in the respiratory center -- an integral brain region governing respiration. Researchers have identified that hydrogen sulfide within the respiratory center plays a crucial role in maintaining
A study has investigated the possible scenarios that could lead to waning memory in some older people.
A recently published study puts forth a new theory that volcanic eruptions combined with widespread ocean detoxification pushed Earth's biology to a tipping point in the Late Devonian era, triggering a mass extinction.
A technology developed over the past few years for controlling microvehicles using ultrasound also works in the brain, as researchers have now been able to show. These microvehicles are gas bubbles, which are harmless and dissolve once their job is done. In the future, these
North Korea and beyond: AI-powered satellite analysis reveals the unseen economic landscape of underdeveloped nations?
A joint research team in computer science, economics, and geography has developed an artificial intelligence (AI) technology to measure grid-level economic development within six-square-kilometer regions. This AI technology is applicable in regions with limited statistical data
Researchers have developed an algorithm to train an analog neural network just as accurately as a digital one, enabling the development of more efficient alternatives to power-hungry deep learning hardware.
A preclinical study shows that a specific human genetic variant of a receptor that stimulates insulin release may help individuals be more resistant to obesity. The researchers discovered that this variant behaves differently in the cell which may contribute to more efficient
Increasing urbanization worldwide is a growing threat to biodiversity. At the same time, flowering plants are often more diverse in cities than in the countryside. This is due to flowering plants and agricultural crops, which are increasingly being grown in cities. A recent
Patients who received the anticoagulant drug warfarin after bioprosthetic aortic valve replacement had lower incidence of mortality and a decreased risk of blood clots, according to a retrospective study.
Ancient DNA analysis reveals how the rise and fall of the Roman Empire shifted populations in the Balkans
Despite the Roman Empire's extensive military and cultural influence on the nearby Balkan peninsula, a DNA analysis of individuals who lived in the region between 1 and 1000 CE found no genetic evidence of Iron Age Italian ancestry. Instead, a new study has revealed successive
A groundbreaking study suggests a class of medications used to treat type 2 diabetes may also reduce the risk of colorectal cancer (CRC). The findings support the need for clinical trials to determine whether these medications could prevent one of the deadliest types of
Comparing PET scans of more than 90 adults with and without mild cognitive impairment (MCI), researchers say relatively lower levels of the so-called 'happiness' chemical, serotonin, in parts of the brain of those with MCI may play a role in memory problems including
A new study of paper wasps suggests social interactions may make animals smarter. The research offers behavioral evidence of an evolutionary link between the ability to recognize individuals and social cooperation.
An unexpectedly high percentage of children, who were born with HIV and started treatment within 48 hours of life, exhibit biomarkers by 2 years of age that may make them eligible to test for medication-free remission, according to a multinational study.
Modern-day Ciudad Mante, Mexico, could help Tampa, Florida, plan for shifting water and electricity demands due to climate change, according to an international team of researchers. Researchers used utilities data and climate analogs -- contemporary cities with climates close
Researchers re-examined a plant fossil found decades ago in Colombia and realized that it wasn't a plant at all: it's a fossilized baby turtle. It's a rare find, because juvenile turtles' shells are soft and often don't fossilize well.
