A healthy lifestyle may prevent heart disease in nearly 3 out of 4 women

A new study published in the Journal of the American College of Cardiology found that adhering to six healthy lifestyle practices can significantly lower the risk of heart attack and cardiovascular disease. The study followed nearly 70,000 women for two decades and found that three-quarters of heart attacks in young women could be prev...

Nutrition education may help prevent breast cancer reoccurrence

Researchers found significant reductions in red and processed meat consumption and increased fruit and vegetable intake among patients who received nutrition education. This led to lower BMI and reduced oxidative stress, potentially decreasing the risk of cancer reoccurrence.

Pfizer grants Georgia State $850,000 to combat smoking in China

Georgia State University will partner with Chinese health officials to expand tobacco control efforts in major cities, protecting non-smokers from second-hand smoke and encouraging smokers to quit. The project aims to curb smoking and increase quit rates in China, where the country produces more tobacco than any other nation.

Seeds out of season

Scientists created a new modeling framework to study the relationships between different stages of a plant's life cycle. The study found that changes in environmental factors can affect the duration of subsequent stages. This research has the potential to improve crop yields and conservation efforts amid climate change.

Study IDs risk factors linking low birthweight to diabetes

A new study confirmed that people born weighing 6 pounds or less face an increased risk for type 2 diabetes as adults. The research identified specific biomarkers with relative predictive value, giving doctors potential new tools to understand individual risk among low birthweight women.

Cation exchange capacity analyzed for nursery pine bark substrates

A study has found that cation exchange capacity varies by pine bark batch, with differences in particle size distribution being a key factor. Substrate pH had no effect on CEC, while adding sphagnum peat did not increase composite CEC. Growers can improve nutrient retention and pH stability by analyzing their substrates for CEC.

SAMSUNG T9 Portable SSD 2TB transfers large imagery and model outputs quickly between field laptops, lab workstations, and secure archives.

Annals of Internal Medicine tip sheet for Jan. 6, 2015

A systematic evidence review found that several common treatments for knee osteoarthritis are effective for pain relief, with injectable therapies being the most effective. The review also introduced a new reporting guideline called TRIPOD to improve the quality of reporting in published articles describing prediction model studies.

A human enzyme (CD 39) targets the Achilles heel of sepsis

New research suggests CD39, an enzyme capable of clearing high levels of adenosine triphosphate from the bloodstream, significantly improves survival of mice in severe sepsis. This discovery holds promise for effective treatment and reduction of costs associated with septic patients in intensive care units.

Hold your breath to protect your heart

Women undergoing left-side breast cancer radiation therapy can reduce heart exposure by holding their breath, resulting in a 90% disease-free survival rate and a median reduction of 62% in radiation dose. The breath-hold technique also shows a lower risk of ischemic heart disease after 8 years.

Fructose more toxic than table sugar in mice

A new study reveals that fructose-glucose mixtures in high-fructose corn syrup are more toxic to female mice than sucrose, reducing reproduction and lifespan. In contrast, male mice showed no significant differences between the two diets.

Apple Watch Series 11 (GPS, 46mm)

Apple Watch Series 11 (GPS, 46mm) tracks health metrics and safety alerts during long observing sessions, fieldwork, and remote expeditions.

Women, quitting smoking for New Years? Time it with your period

Research reveals that women experience stronger urges to smoke at the beginning of their menstrual cycle due to hormonal changes. This knowledge could help women overcome abstinence-related withdrawal symptoms more easily, especially during the mid-luteal phase when estrogen and progesterone levels are higher.

Predicting superbugs' countermoves to new drugs

Duke University researchers develop software to predict genetic changes in bacteria that will allow it to evade new experimental drugs. The team successfully identified four mutations that would confer resistance, with over half of surviving colonies carrying the predicted mutation.

New analyses of Martian chemical maps suggest water bound to sulfates in soil

A new study suggests that water is bound to sulfates in Martian soil, a key finding with implications for the search for life on Mars. The research team analyzed elemental data from the Gamma Ray Spectrometer onboard the Mars Odyssey orbiter and found a spatial association between sulfur and hydrogen in the southern latitudes of Mars.

Not all obese people develop metabolic problems linked to excess weight

A study at Washington University School of Medicine found that a subset of obese individuals do not develop common metabolic abnormalities associated with obesity, such as insulin resistance and high blood pressure. In contrast, those who already had these problems worsened after gaining weight.

Garmin GPSMAP 67i with inReach provides rugged GNSS navigation, satellite messaging, and SOS for backcountry geology and climate field teams.

New version of common antibiotic could eliminate risk of hearing loss

Researchers at Stanford University School of Medicine have developed a modified version of an aminoglycoside that works effectively in mice without causing deafness or kidney damage. The new antibiotic, N1MS, was created by modifying the drug molecule to prevent it from entering the inner-ear cell's ion channels.

Innate behavior determines how we steer our car

Researchers at Chalmers University of Technology have developed a driver model that can predict steering movements up to 95% accurately. This breakthrough may lead to safer car systems, including anti-skid and fatigue detection systems.
