Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
Females outnumber men in biology at the undergraduate and Ph.D. levels and have this entire century. Where do they still lag? Faculty positions.
The issue is clearly not sexism, academia prides itself on being more liberal and inclusive than private sector science, it is the tenure system. Tenured scientists are living longer, continuing to do fine work, and therefore not making way for younger female scientists who have an advantage in hiring now.
Researchers are exploring ways to help clinicians and investigators use and share routinely collected medical data (such as information in electronic health records) to improve care and advance clinical research.
In a recent article, experts note that with the development of platforms enabling the use of routinely collected clinical data in the context of international research, scalable solutions for cross-border and cross-domain interoperability need to be developed.
"We provide insights on the requirements needed to achieve this and the need for a rigorous governance process to ensure the quality of data standardization," said Dr. Christel Daniel, lead author of the Learning Health Systems article.
Proximity is an important influence in consumer decisions on everyday purchases, according to a new survey.
In the survey, 93.2 percent of respondents said they typically travel less than 20 minutes to buy groceries, clothing, gas, and other routine transactions, while 87 percent said they won’t travel beyond 15 minutes for such purchases. For purchases that consumers make at least once per week, the distance they’re willing to travel shrinks even further to ten minutes.
A paper by researchers at LSU Health New Orleans in a little known journal called Translational Cancer Research suggests that age is an important factor in the association between cancer and sugar-sweetened beverages and recommends that intervention programs to reduce consumption of added sugar be focused on lower socio-economic status, young males, as well as cervical cancer survivors. Sugar intake or sugar-sweetened beverage consumption has also been associated with obesity, diabetes and cardio-metabolic diseases, and just about everything else. As more people are surviving cancer, the consumption of added sugar will be an increasingly important risk factor.
According to a music researcher, discrimination of women is common in the club scene. Female DJs don’t get gigs because the music they play is “too feminine.”
It's no secret that elite clubs are fast-tracking customers that fit the "vibe" they are trying to create, but it isn't just the young, pretty ones. If the clothes are wrong, they will not get past the velvet rope, and that's discrimination, argues Tami Gadir, a post-doctoral fellow at the Department of Musicology at the University of Oslo, who is researching women’s experiences in the electronic music scene. She is studying female DJs in particular, but in her experience, the gender differences pervade the electronic club scene in its entirety.
Scientists have measured the catastrophic genetic damage caused by smoking in different organs of the body and identified several different mechanisms by which tobacco smoking causes mutations in DNA. The researchers found that smokers accumulated an average of 150 extra mutations in every lung cell for each year of smoking one pack of cigarettes a day.
In rare cases, someone who is thin could still end up with type 2 diabetes while an obese person may be surprisingly healthy. Some Asian countries have a higher diabetes rate than the United States even though the obesity rate is relatively low. New research points toward an answer to the riddle of the obesity paradox: An accumulation of a toxic class of fat metabolites, known as ceramides, may increase the risk for type 2 diabetes.
Among patients in Singapore receiving gastric bypass surgery, ceramide levels predicted who had diabetes better than obesity did. Even though all of the patients were obese, those who did not have type 2 diabetes had less ceramide in their adipose tissue than those who were diagnosed with the condition.
Evolutionary biology long ago solved the philosophical conundrum 'what came first, the chicken or the egg?' by showing that eggs came long before chickens. But more relevant to evolution is the 'mother' molecule that led to the formation of life. What is it and how did it replicate itself?RNA may be the answer to the first question, because it has more flexibility in how it recognizes itself than previously believed. The finding might change how we picture the first chemical steps towards replication and life.
With the aid of a new immunosuppressive agent known as PIF (preimplantation factor), researchers at the World Health Organisation (WHO) Institute of Primate Research in Nairobi, Kenya, have successfully transplanted an ovary from one individual to another, even managing to restore a monthly cycle. Approximately 11 percent of women worldwide suffer from premature ovarian failure. This can have many different causes: chemotherapy administered for a malignant disease might irreversibly damage the ovaries and, because of the advances in modern cancer therapy, the number of young women surviving cancer is on the increase. The women, some of whom are still very young, prematurely enter menopause. Genetic diseases can also trigger early menopause.
It would seem obvious that a diluted nicotine vapor is much less harmful than toxic chemicals in cigarette smoke - yet groups like the Centers for Disease Control and Tobacco Free Kids have instead adopted a 'quit or die' mentality about smoking.Yet we engage in harm reduction when it comes to needle exchanges and, strangely, the political party that was against those is for e-cigarettes, while the party that is on the other side wants any smoking cessation or harm reduction tool not controlled by pharmaceutical companies to be penalized.
Thanks, but no thanks, say British scientists about controversial British evolutionary biologist Richard Dawkins, primarily known for his criticism of religion.A majority of those surveyed who mentioned Dawkins’ work during research interviews reject his approach to public engagement and said his work misrepresents science and scientists because he conveys the wrong impression about what science can do and the norms that scientists observe in their work.
The giant planets in our solar system have very diverse rings. Observations show that Saturn’s rings are made of more than 95% icy particles, while the rings of Uranus and Neptune are darker and may have higher rock content. Since the rings of Saturn were first observed in the 17th century, investigation of the rings has expanded from earth-based telescopes to spacecraft such as Voyagers and Cassini. However, the origin of the rings was still unclear and the mechanisms that lead to the diverse ring systems were unknown.
