Less sugar, please! New studies show low glucose levels might assist muscle repair

by

Researchers from Tokyo Metropolitan University have shown that skeletal muscle satellite cells, key players in muscle repair, proliferate better in low glucose environments. This is contrary to conventional wisdom that says mammalian cells fare better when there is more sugar to fuel their activities.

Because ultra-low glucose environments do not allow other cell types to proliferate, the team could produce pure cultures of satellite cells, potentially a significant boost for biomedical research.

Healthy muscles are an important part of a healthy life. With the wear and tear of everyday use, our muscles continuously repair themselves to keep them in top condition. In recent years, scientists have begun to understand how muscle repair works at the cellular level. [Read more…] about Less sugar, please!

Researchers discover new type of ancient crater lake on Mars

by

Researchers from Brown University have discovered a previously unknown type of ancient crater lake on Mars that could reveal clues about the planet’s early climate.

In a study published in Planetary Science Journal, a research team led by Brown Ph.D. student Ben Boatwright describes an as-yet unnamed crater with some puzzling characteristics.

The crater’s floor has unmistakable geologic evidence of ancient stream beds and ponds, yet there’s no evidence of inlet channels where water could have entered the crater from outside, and no evidence of groundwater activity where it could have bubbled up from below.

How to prevent and treat high blood pressure with exercise

by

The first personalised advice on the most effective exercise to lower blood pressure is published today in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC). The ESC consensus document recommends specific activities according to an individual’s current blood pressure level.

One in four heart attacks are caused by high blood pressure. It is estimated that by 2025, around 60% of the world’s population will have hypertension. While it is widely accepted that exercise lowers blood pressure, until now recommendations have focused on the amount of exercise per week, without considering an individual’s starting blood pressure level.

This consensus document, for the first time, used an analysis of the highest quality evidence to produce detailed guidance on how to lower blood pressure in people with hypertension, high-normal blood pressure, and normal blood pressure.

Medicaid expansion made mouths healthier, study finds

by

As the pandemic’s economic effects drive more people to enroll in Medicaid as safety-net health insurance, a new study suggests that the program’s dental coverage can improve their oral health in ways that help them seek a new job or do better at the one they have.

The study focuses on the impact of dental coverage offered through Michigan’s Medicaid expansion, called the Healthy Michigan Plan. The researchers, from the University of Michigan, used a survey and interviews to assess the impact of this coverage on the health and lives of low-income people who enrolled.

In all, 60% of the 4,090 enrollees surveyed for the new study had visited a dentist at least once since enrolling in the Healthy Michigan Plan a year or two earlier, which the researchers verified with state records. [Read more…] about Medicaid expansion made mouths healthier, study finds

NASA scientists complete first global survey of freshwater fluctuation

by

To investigate humans’ impact on freshwater resources, scientists have now conducted the first global accounting of fluctuating water levels in Earth’s lakes and reservoirs – including ones previously too small to measure from space.

The research, published March 3 in the journal Nature, relied on NASA’s Ice, Cloud and land Elevation Satellite 2 (ICESat-2), launched in September 2018.

ICESat-2 sends 10,000 laser light pulses every second down to Earth. When reflected back to the satellite, those pulses deliver high-precision surface height measurements every 28 inches (70 centimeters) along the satellite’s orbit.

Diverse ecosystem provides our livelihoods, according to research

by

Functioning ecosystems provide the basis for security, basic material needs, health, social interaction and individual liberty. 

This is how the Millennium Ecosystem Assessment 2005 described it, dividing ecosystem services into the following categories:

  • the provisioning services; goods such as food, water, firewood and timber, the regulating services;
  • pollination, water filtering function of the soil, flood and erosion protection, and the cultural services; and
  • recreation, places of inspiration, and education.

Many of these services are indirectly and directly linked to the presence of species. For this reason, species conservation is often put forward as a measure for the conservation of vital natural services. [Read more…] about Diverse ecosystem provides our livelihoods, according to research

An instructor’s guide to reducing college students’ stress and anxiety

by

Even before the COVID-19 pandemic, college students were reporting record levels of stress and anxiety. According to the American College Health Association Fall 2018 National College Health Assessment, 63% of U.S. college students experienced overwhelming anxiety throughout the year.

Plus, stress can impact students’ academic performance, and students with higher stress levels are more at-risk of withdrawing from college – often permanently. Given these complex mental health issues, all hands are needed on deck to support student success.

A new review from Chapman University’s Schmid College of Science and Technology and Grand Challenges Initiative provides actionable and evidence-based strategies for instructors to help combat the ongoing epidemic of stress and anxiety among college and university students, with a focus on students in STEM disciplines.

The right ‘5-a-day’ mix is 2 fruit and 3 vegetable servings for longer life

by

Studies representing nearly 2 million adults worldwide show that eating about five daily servings of fruits and vegetables, in which 2 are fruits and 3 are vegetables, is likely the optimal amount for a longer life, according to new research published today in the American Heart Association’s flagship journal Circulation.

Diets rich in fruits and vegetables help reduce risk for numerous chronic health conditions that are leading causes of death, including cardiovascular disease and cancer. Yet, only about one in 10 adults eat enough fruits or vegetables, according to the U.S. Centers for Disease Control and Prevention.

“While groups like the American Heart Association recommend four to five servings each of fruits and vegetables daily, consumers likely get inconsistent messages about what defines optimal daily intake of fruits and vegetables such as the recommended amount, and which foods to include and avoid,” said lead study author Dong D. Wang, M.D., Sc.D., an epidemiologist, nutritionist and a member of the medical faculty at Harvard Medical School and Brigham and Women’s Hospital in Boston.

Long black, espresso, or latte, whatever your coffee preference, drink too much and you could be in hot water, especially when it comes to heart health.

In a world first genetic study, researchers from the Australian Centre for Precision Health at the University of South Australia found that that long-term, heavy coffee consumption – six or more cups a day – can increase the amount of lipids (fats) in your blood to significantly heighten your risk of cardiovascular disease (CVD).

Importantly, this correlation is both positive and dose-dependent, meaning that the more coffee you drink, the greater the risk of CVD. [Read more…] about Déjà brew? Another shot for lovers of coffee

Coffee lovers, rejoice! Drinking more coffee associated with decreased heart failure risk

by

Dietary information from three large, well-known heart disease studies suggests drinking one or more cups of caffeinated coffee may reduce heart failure risk, according to research published today in Circulation: Heart Failure, an American Heart Association journal.

Coronary artery disease, heart failure and stroke are among the top causes of death from heart disease in the US.

“While smoking, age and high blood pressure are among the most well-known heart disease risk factors, unidentified risk factors for heart disease remain,” according to David P. Kao, MD, senior author of the study, assistant professor of cardiology and medical director at the Colorado Center for Personalized Medicine at the University of Colorado School of Medicine in Aurora, Colorado.

“The risks and benefits of drinking coffee have been topics of ongoing scientific interest due to the popularity and frequency of consumption worldwide,” said Linda Van Horn, PhD, RD, professor and Chief of the Department of Preventive Medicine’s Nutrition Division at the Northwestern University Feinberg School of Medicine in Chicago, and member of the American Heart Association’s Nutrition Committee.
