Scientists consider the role of overweight and obesity in increasing the risk for gastrointestinal cancers to be well established, with colorectal cancers the most common of these malignancies in the United States. According to National Cancer Institute (NCI) data, an estimated 153,020 men and women in the U.S. will be diagnosed with colorectal cancer in 2023, and 52,550 are expected to die of this disease. In two recent studies, researchers addressed the impact of overweight, obesity, and body mass index (BMI) on colorectal and non-colorectal gastrointestinal (GI) cancers at different stages of adult life, as well as the association of BMI and different molecular subtypes in colorectal cancers.

Obesity, BMI, and Cancer Across the Lifespan

In a new retrospective cohort study, researchers found that being overweight or obese in early and middle adulthood increases the risk for developing colorectal and non-colorectal GI cancers throughout a person’s lifetime. Even when an individual starts out as underweight or falls within a normal BMI as a young adult, the risk rises if they later become overweight or obese, according to the research.

For decades, people have arranged to freeze their bodies after death, dreaming of resurrection by advanced future medicine.

The signal, produced by neurons, helps the barrier form and maintain its protective properties.

In the largest observational study to date on “SuperAgers” — people in their 80s who have brains as sharp as those 30 years younger — researchers in Spain found key differences in lifestyle that may contribute to these older adults’ razor-sharp minds.

SuperAgers in the study had more gray matter in parts of the brain related to movement, and they scored higher on agility, balance and mobility tests than typical older adults — even though the physical activity levels of the two groups were the same.

“Though superagers report similar activity levels to typical older people, it’s possible they do more physically demanding activities like gardening or stair climbing,” said senior author Bryan Strange, director of the Laboratory for Clinical Neuroscience at the Technical University of Madrid, in a statement.

Prior to school getting under way is an ideal time to review your child’s needs for coping with allergies and asthma.

Immunotherapy could be the “shot in the arm” you need to treat your allergies.

ARLINGTON HEIGHTS, Ill. (August 7, 2019) – You may think you can’t tell the difference between the symptoms caused by spring, summer and fall allergies. They all usually involve sneezing, sniffling, itchy eyes and a runny nose. And while symptoms for each Allergies are inappropriate or exaggerated reactions of the immune system to substances that, in the majority of people, cause no symptoms. Symptoms of the allergic diseases may be caused by exposure of the skin to a chemical, of the respiratory system to particles of dust or pollen (or other substances), or of the stomach and intestines to a particular food. rel= tooltip allergy season may be similar, the treatment can look very different, particularly if Immunotherapy is a form of preventive and anti-inflammatory treatment of allergy to substances such as pollens, house dust mites, fungi, and stinging insect venom.

Companion robots enhanced with artificial intelligence may one day help alleviate the loneliness epidemic, suggests a new report from researchers at Auckland, Duke, and Cornell Universities.

Their report, appearing in the July 12 issue of Science Robotics, maps some of the ethical considerations for governments, policy makers, technologists, and clinicians, and urges stakeholders to come together to rapidly develop guidelines for trust, agency, engagement, and real-world efficacy.

It also proposes a new way to measure whether a companion robot is helping someone.

A new study explored the causal role that music engagement has on student achievement in mathematics—and they found a significant benefit.

Researchers believe that music can make math more enjoyable, keep students engaged, and help ease their fear or anxiety about topics like fractions. The addition of music may even motivate kids to appreciate math and want to learn more.

A typical technique for integrating music into math lessons for young children involves clapping to songs with different rhythms learning numbers, and equating fractions to musical notes.

So why, almost 30 years on from Dolly, haven’t humans been cloned yet? Is it primarily for ethical reasons, are there technological barriers, or is it simply not worth doing?
