The Arctic is warming at approximately twice the global rate. A new study led by researchers from McGill University finds that cold-adapted Arctic species, like the thick-billed murre, are especially vulnerable to heat stress caused by climate change.

A new study examining why young South Asian heart attack patients have more adverse outcomes found this patient population was often obese, used tobacco products, and had a family history of heart disease or risk factors that could have been prevented, monitored for or treated before heart attacks happen. The study will be presented at the ACC Asia 2021 Together with SCS 32nd Annual Scientific Meeting Virtual being held July 9-11, 2021.

Data from nine cities in Mexico confirms that identifying dengue fever "hot spots" can provide a predictive map for future outbreaks of Zika and chikungunya. All three of these viral diseases are spread by the Aedes aegypti mosquito.

When a head of state or government official travels to another country to meet with his/her counterpart, the high-level visit often entails a range of public diplomacy activities as hosting a joint press conference, or attending a sports event, which aim to increase public support in the host country. A new study finds that public diplomacy accompanying a high-level visit by a national leader increases public approval in the host country.

A new study shows patients with mild-to-moderate Parkinson's disease (PD) can slow the progress of the disease by participating in dance training with music for one-and-a-quarter hours per week. Over the course of three years, this activity was found to reduce daily motor issues such as those related to balance and speech, which often lead to social isolation.

For patients with pancreatic ductal adenocarcinomas (PDAC), molecular imaging can improve staging and clinical management of the disease, according to research published in the June issue of The Journal of Nuclear Medicine. In a retrospective study of PDAC patients, the addition of PET/CT imaging with 68Ga-FAPI led to restaging of disease in more than half of the patients, most notably in those with local recurrence.

The discovery of novel groups or categories within diseases, organisms and biological processes and their organization into hierarchical relationships are important and recurrent pursuits in biology and medicine, which may help elucidate group-specific vulnerabilities and ultimately novel therapeutic interventions.

A decade's worth of data shows that neonatologists are shifting the type of respiratory support they utilize for preterm infants, a move that could lead to improved health outcomes.

Dutch-French research shows that Optical Genome Mapping (OGM) detects abnormalities in chromosomes and DNA very quickly, effectively and accurately. Sometimes even better than all existing techniques together, as they describe in two proof-of-concept studies published in the American Journal of Human Genetics. This new technique could radically change the existing workflow within cytogenetic laboratories.

A team based at the University of Kansas and China performed fieldwork in the Junggar Basin to discover two fossil teeth belonging to two separate specimens of bat, dubbed Altaynycteris aurora. It's the oldest fossil of bat found in Asia.

Testing returned to pre-pandemic levels in late 2020 except with colonoscopies for colorectal cancer screening, which continued to lag. Rates of mammography for breast cancer screening were lower among Black and Hispanic patients during the pandemic. Long term effects of "missed" diagnoses on cancer outcomes not yet clear.

An MIT study shows radioactive molecules are sensitive to subtle nuclear phenomena. The molecules might help physicists probe violation of the most fundamental symmetries of nature, including why the universe contains relatively little antimatter.

How do predators know to avoid brightly-coloured toxic prey? A collaboration of researchers has put social information theory to the test in a reliable real-world system to find the answer - by copying what others do, or do not, eat.

Scientists show for the first time with a VR simulation and neurophysiology measurements that playback of slow music inside road tunnels keeps drivers alert, relaxed, and focused on safety. For maximal vigilance, alarm sounds like sirens should be played at the tunnel's entry and exit, where the risk of accidents is greatest. This study by the open access publisher Frontiers shows that background music has a role to play in preventing road accidents.

The Hikurangi Margin, located off the east coast of the North Island of New Zealand, is partly responsible for the more than 15,000 earthquakes the region experiences each year. Most are too small to be noticed, but between 150 and 200 are large enough to be felt. Scientists have been working to understand why this plate boundary produces both imperceptible silent earthquakes, but also potentially major ones. A study published today in the journal Nature offers new perspective and possible answers.

Researchers have developed a patch that plants can "wear" to monitor continuously for plant diseases or other stresses, such as crop damage or extreme heat.

Scientists from Trinity College Dublin are homing in on a recipe that would enable the future production of entirely renewable, clean energy from which water would be the only waste product. Using their expertise in chemistry, theoretical physics and artificial intelligence, the team is now fine-tuning the recipe with the genuine belief that the seemingly impossible will one day be reality.

EMBL´s Typas group and colleagues have analysed how the intracellular pathogen Salmonella enterica secretes proteins to survive and thrive in infected cells. Using a novel approach, which for the first time allows scientists to study which host cell proteins are targeted by the pathogen, the scientists revealed new insights into how Salmonella hijacks the cell´s cholesterol supplies, and how it rewires cellular transport processes to promote its own survival.

Astronomers led by David Yong, Gary Da Costa and Chiaki Kobayashi from Australia's ARC Centre of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D) based at the Australian National University (ANU) have potentially discovered the first evidence of the destruction of a collapsed rapidly spinning star - a phenomenon they describe as a "magneto-rotational hypernova".

Diversification in the sourcing of food into cities can go a long way to tempering "food shock" -- a sudden drop in food supply due to unforeseen events, according to a team of researchers from Penn State and Northern Arizona University, who developed a statistical risk model linking supply chain diversity to the probability of a city experiencing food shocks.
