In this special report, the authors argue that the current primary care team paradigm is underpowered, in that most of the administrative responsibility still falls mainly on the physician. Jobs not requiring a medical education, such as entering data into electronic health records, should not be handled by physicians and advanced practitioners.

The Astana Declaration, adopted by the World Health Organization in October 2018, acknowledges the importance of primary health care to achieve better health outcomes globally. But how, the authors ask, can physicians make this declaration work? Family physicians, the authors argue, can serve an important role in improving primary health care if they are better integrated "horizontally," translating their localized knowledge of health trends to wider populations and communities.

A massive complex of thunderstorms over the southeastern United States slid into the northeastern Gulf of Mexico and now has the potential to develop into a tropical cyclone. NOAA's National Hurricane Center or NHC in Miami, Florida issued the first advisory of Potential Tropical Cyclone Two and NOAA's GOES-East satellite and NASA's GPM satellite provided views of the storm.

Wandering through the Harvard campus one day in 2015, graduate student Andrew Yegian recalls how something unusual caught his eye. 'I noticed a person running with straight arms', he explains. This really stood out for Yegian, as runners usually bend the elbow, while walkers keep their arms straight, which made him wonder: 'If straight arms are better for walking, why aren't they better for running, and vice versa?' he puzzled. Was there a trade-off between the cost of keeping the elbow bent and swinging the arm at the shoulder that could benefit runners?

The movie Finding Nemo could have a much darker sequel - as artificial light in coral reefs leaves the famous fish unable to reproduce offspring, according to a new study.

Results by Flinders University and the University of Melbourne published in Biology Letters show an increasing amount of artificial light at night (ALAN) in coral reefs, even at relatively low levels, masks natural cues which trigger clownfish eggs to hatch after dusk.

Platelet cells, which prevent mammals from bleeding non-stop, first evolved around 300 million years ago in an egg-laying animal similar to the modern duck-billed platypus, finds joint research by UCL and Yale University.

This event was a prerequisite for the origin of placental development in mammals, including human beings.

CORVALLIS, Ore. - The most extensive and systematic insect monitoring program ever undertaken in North America shows that butterfly abundance in Ohio declined yearly by 2%, resulting in an overall 33% drop for the 21 years of the program.

Coral reefs are retreating from equatorial waters and establishing new reefs in more temperate regions, according to new research in the journal Marine Ecology Progress Series. The researchers found that the number of young corals on tropical reefs has declined by 85 percent - and doubled on subtropical reefs - during the last four decades.

Drylands cover approximately 50% of the land surface in China, among which semi-arid regions are the main dryland type. However, these semi-arid regions have undergone continuous expansion and a significant drying trend in recent decades, which increases the risk of land degradation and deterioration in China. Fully understanding the characteristics and dynamics of semi-arid climate change in China is essential for delaying desertification, protecting renewable regional resources and developing reasonable policies, according to Prof.

A deep learning-powered computational framework, 'DeepEC,' will allow the high-quality and high-throughput prediction of enzyme commission numbers, which is essential for the accurate understanding of enzyme functions.

A team of Dr. Jae Yong Ryu, Professor Hyun Uk Kim, and Distinguished Professor Sang Yup Lee at KAIST reported the computational framework powered by deep learning that predicts enzyme commission (EC) numbers with high precision in a high-throughput manner.

The ability to control infrared and terahertz waves using magnetic or electric fields is one of the great challenges in physics that could revolutionise opto-electronics, telecommunications and medical diagnostics. A theory from 2006 predicts that it should be possible to use graphene - a monoatomic layer of carbon atoms- in a magnetic field not only to absorb terahertz and infrared light on demand but also to control the direction of the circular polarisation.

Chinese scientists have made significant progress on the influence of the Northern Hemisphere mid-high latitudes on East Asian climate, according to Prof. Jianping Li, offrom the Key Laboratory of Physical Oceanography-Institute for Advanced Ocean Studies, Ocean University of China and Qingdao National Laboratory for Marine Science and Technology, and the lead/corresponding author of a study recently published in Advances in Atmospheric Sciences.

A boiling point of 5900 degrees Celsius and diamond-like hardness in combination with carbon: tungsten is the heaviest metal, yet has biological functions - especially in heat-loving microorganisms. A team led by Tetyana Milojevic from the Faculty of Chemistry at the University of Vienna report for the first time rare microbial-tungsten interactions at the nanometer range. Based on these findings, not only the tungsten biogeochemistry, but also the survivability of microorganisms in outer space conditions can be investigated.

Cheetah experts in many zoos around the world are at a loss. Despite all their efforts, these cats often do not reproduce in the desired manner. Researchers from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW), together with colleagues from the Allwetterzoo Münster, have now found a key to the issue: the age of the mothers at the first pregnancy is the decisive factor. In contrast to the wild, felines kept in zoos are often bred only years after they have reached sexual maturity.

WASHINGTON, D.C., July 9, 2019 -- Microfluidics and learning-on-a-chip research -- involving the manipulation of small amounts of fluids to run miniaturized experiments in physics, chemistry, biology and medicine -- are a prolific research field. But, so far, there aren't many published examples of how to teach it in an easily understandable way to students or how to communicate the numerous significant advances within the field to public audiences in a relatable manner.
