A study published in the JAMA Otolaryngology-Head & Neck Surgery examines the effect of Medicaid expansion on head and neck cancer patients, finding that the expansions under the Affordable Care Act (ACA) were associated with improved access to care for these patients and selective Medicaid expansion may worsen existing regional disparities in terms of access to care and outcomes.

Cross-border regions have great potential for cooperation, yet very few border regions are integrated, a new study from the University of Eastern Finland shows. Conducted by Dr Francesco Cappellano and Professor Teemu Makkonen at the University of Eastern Finland's Karelian Institute, the study sheds light on the fact that although there is plenty of talk about promoting integration in cross-border regions, the reality is very different.

Researchers have found evidence of rainforests near the South Pole 90 million years ago, suggesting the climate was exceptionally warm at the time.

A team from the UK and Germany discovered forest soil from the Cretaceous period within 900 km of the South Pole. Their analysis of the preserved roots, pollen and spores shows that the world at that time was a lot warmer than previously thought.

CAMBRIDGE, MA -- Using a specialized magnetic resonance imaging (MRI) sensor, MIT neuroscientists have discovered how dopamine released deep within the brain influences both nearby and distant brain regions.

In many regions of the world, farming must be done on areas of soil categorized as histosols. Histosols have a thick layer of rich organic matter, called peat.

Scientists are concerned, because farming can cause these soils to lose valuable carbon.

That's where Jacynthe Dessureault-Rompre? and her team at Laval University in Canada come in. She is trying to show that histosols can be sustainably used for farming.

The only way to accurately measure pressure inside the skull is to insert a catheter or sensor inside. However, this is invasive and techniques with less risk are desired. Intracranial pressure (ICP) needs to be correctly accounted for in a variety of medical situations including neurosurgery, neurology and emergency medicine.

Actuators that can convert various environmental stimuli to mechanical works have revealed great potential for developing smart devices such as soft robots, micro-electromechanical systems (MEMS), and automatic Lab-on-a-Chip systems. Generally, bilayer structures are widely used for design and fabrication of stimuli responsive actuators. In the past decade, to pursue fast and large-scale deformation, great efforts have been devoted to the development of novel smart materials.

Scientists have mapped the genome of the German shepherd, one of the world's most popular canine breeds, after using a blood sample from 'Nala,' a healthy five-year-old German shepherd living in Sydney.

In a paper published today in respected 'big data' journal GigaScience, a global team of researchers from institutions including UNSW Sydney detailed the mammoth task of unravelling the 38 pairs of dog chromosomes to decode the 19,000 genes and 2.8 billion base pairs of DNA, using advanced genetic sequencing technology.

The formation pressure governs the generation, expulsion, migration, accumulation and preservation of petroleum. Fluid-rock interactions during diagenesis and mineralization are also affected by the formation pressure. Thus, investigating the formation paleo-pressure in sedimentary basins is an important aspect of research into the mechanisms and processes related to hydrocarbon accumulation, and it plays an increasingly important role in hydrocarbon exploration and prospective prediction.

Eggs have been acknowledged as a good source of high-quality proteins and contain bioactive components beneficial for health, while they are also loaded with abundant cholesterol in the yolks, making the public hesitant about consuming whole eggs. Up to now, most studies exploring the association of egg consumption with incident CVD or total death were conducted in high-income countries and findings were inconsistent across populations and CVD subtypes. Accordingly, no consensus has been reached on the recommendation of egg consumption around the world.

China's fast economic growth and accompanying rise in food demand are driving an increase in water use for agriculture and industry, thus threatening the country's water security. The findings of a new study underscore the value and potential of technological adoptions to help design targets and incentives for water scarcity mitigation measures.

Across the world, animals are kept in captivity for various reasons: in zoos for education and research, in research facilities for testing, on farms for meat and other products, and in people's homes as pets. Maintaining good animal welfare is not only important for ethical reasons; poor welfare can impact human wellbeing and the economy. But how do we assess how animals are feeling?

Meat is no ordinary solid. Made up of complex networks of moisture-saturated proteins, it displays some intriguing physical properties when it is cooked. Several studies in the past have attempted to recreate this behaviour in computer simulations, but because this demands so much computing power, they have only achieved simplified, one-dimensional recreations of the process, which aren't particularly accurate.

ITHACA, N.Y. - Daily life during a pandemic means social distancing and finding new ways to remotely connect with friends, family and co-workers. And as we communicate online and by text, artificial intelligence could play a role in keeping our conversations on track, according to new Cornell University research.

BUFFALO, N.Y. - Activity from phony Twitter accounts established by the Russian Internet Research Agency (IRA) between 2015 and 2017 may have contributed to politicizing Americans' position on the nature and efficacy of vaccines, a health care topic which has not historically fallen along party lines, according to new research published in the American Journal of Public Health.
