As political leaders debate the merits of a future Medicare for All system in the U.S., some analysts predict that implementing universal coverage could cause a sharp, unaffordable increase in hospital use and costs, overwhelming the system. But new research by a team at Harvard Medical School and The City University of New York at Hunter College, published today in the Annals of Internal Medicine, contradicts that assumption, finding that past insurance expansions did not result in a net increase in hospital use.
Berkeley -- Before bite-sized crustaceans like crayfish, shrimp and prawns land on our dinner plates, they first have to get fat themselves -- and it turns out they relish the freshwater snails that transmit the parasite that causes schistosomiasis, the second most devastating parasitic disease worldwide, after malaria.
CHAPEL HILL, North Carolina - Researchers at the UNC Lineberger Comprehensive Cancer Center have discovered a hyperactive cell signal that contributes to tumor growth in an aggressive blood cancer. They also developed an experimental therapeutic to block the signal and slow tumor growth.
Many people complain about television shows that use recorded laugh tracks. But researchers reporting in the journal Current Biology on July 22 have found that laugh tracks really do work.
According to the new evidence, the sound of a laugh track makes people rate corny "dad jokes" as being funnier. Laugh tracks work best when the recording features spontaneous laughter as opposed to posed laughter. The findings held up in both neurotypical people and in those diagnosed with autism.
Meteoroids coming from outer space are randomly shaped, but many of these, which land on earth as meteorites, are found to be carved into cones. Scientists have now figured out how the physics of flight in the atmosphere leads to this transformation.
PITTSBURGH, July 22, 2019 - In the time it takes you to read this sentence, every cell in your body suffers some form of DNA damage. Without vigilant repair, cancer would run rampant, and now scientists at the University of Pittsburgh have gotten a glimpse of how one protein in particular keeps DNA damage in check.
Cold Spring Harbor, NY -- Scientists haven't quite decoded how animals smell, but researchers at Cold Spring Harbor Laboratory (CSHL) found that it's different from previously thought.
To understand how the brain processes and interprets smells, CSHL neuroscientists Florin Albeanu, Alexei Koulakov and colleagues Honggoo Chae, Daniel Kepple, Walter Bast from CSHL, and Venkatesh Murthy from Harvard University, are putting past odor classifying models to the test, and they're discovering discrepancies.
A new study has found that an Inuit population in Canada's Arctic are genetically distinct from any known group, and certain genetic variants are correlated with brain aneurysm.
Geographically isolated populations often develop unique genetic traits that result from their successful adaptation to specific environments. Unfortunately, these adaptations sometimes predispose them to certain health issues if the environment is changed. The genetic background of these populations are often poorly understood because they live far from scientific research centres.
Reports of racially motivated, fatal shootings by police officers have garnered extensive public attention and sparked activism across the nation. New research from Michigan State University and University of Maryland reveals findings that flip many of these reports on their heads - white police officers are not more likely to shoot minorities citizens than non-white officers.
A new mathematical model describes how highly concentrated antibody solutions separate into different phases, similar to an oil and water mixture. This separation can reduce the stability and shelf-life of some drugs that use monoclonal antibodies, including some used to treat autoimmune diseases and cancer.
Bottom Line: This study (called a systematic review and meta-analysis) combined the results of nine studies and examined the association between adherence to plant-based eating habits and risk of type 2 diabetes in adults. The analysis included 307,099 adults with 23,544 cases of type 2 diabetes. The authors report higher adherence to plant-based eating habits was associated with lower risk of type 2 diabetes, especially when only healthy plant-based foods, such as fruits, vegetables, whole grains, legumes and nuts, were included in the definition of plant-based.
To answer the question, "Where's Waldo?" readers need to look for a number of distinguishing features. Several characters may be spotted with a striped scarf, striped hat, round-rimmed glasses, or a cane, but only Waldo will have all of these features.
One of the 21st century's greatest challenges is to develop diets that are both sustainable for the planet and good for our bodies. An IIASA-led study explored the major drivers of widespread shifts to sustainable diets using a newly developed computational model of population-wide behavioral dynamics.
A decade without any global warming is more likely to happen if the climate is more sensitive to carbon dioxide emissions, new research has revealed.
A team of scientists from the University of Exeter and the Centre of Ecology and Hydrology in the UK has conducted pioneering new research into why both surges and slowdowns of warming take place.
Using sophisticated climate models the team, led by PhD student Femke Nijsse, discovered if the climate was more sensitive to CO2 concentration also displayed larger variations of warming over a decade.
UNIVERSITY PARK, Pa.--Plants may induce "leaky gut syndrome"--permeability of the gut lining--in insects as part of a multipronged strategy for protecting themselves from being eaten, according to researchers at Penn State. By improving our understanding of plant defenses, the findings could contribute to the development of new pest control methods.
