Fruit and Vegetable Consumption Could Lead to Longer Life

In the two prospective cohorts with many repeated measurements of diet and up to 30 years of follow-up, Wang et al. observed that a higher intake of fruit and vegetables was associated with a lower risk of total mortality and cause-specific mortality; their analysis in the NHS and the HPFS and in a meta-analysis of 26 prospective cohort studies documented that intake of approximately 5 servings of fruits and vegetables daily was associated with the lowest mortality, and higher intake was not associated with additional risk reductions in mortality.

A team of U.S. researchers has found an inverse association between fruit and vegetable intake and mortality in two large prospective cohorts, the Nurses’ Health Study (NHS) and the Health Professionals Follow-up Study (HPFS), with detailed and repeated dietary measurements and long follow-up; the lowest risk of mortality was observed for approximately five daily servings of fruits and vegetables, eaten as two servings of fruit and three servings...

Osteoclasts are large multinucleated bone-resorbing cells formed by the fusion of monocyte/macrophage-derived precursors that are thought to undergo apoptosis once resorption is complete; By intravital imaging, we reveal that RANKL-stimulated osteoclasts have an alternative cell fate in which they fission into daughter cells called osteomorphs.

This Hubble image shows NGC 2336, a barred spiral galaxy located 109 million light-years away in the constellation of Camelopardalis. The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS). Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This painting depicts an asteroid slamming into tropical, shallow seas of the sulfur-rich Yucatan Peninsula in what is today southeast Mexico. The aftermath of this immense asteroid collision, which occurred approximately 65 million years ago, is believed to have caused the extinction of the dinosaurs and many other species on Earth. Shown in this painting are pterodactyls, flying reptiles with wingspans of up to 50 feet, gliding above low tropical clouds. Image credit: Donald E. Davis / NASA.

When flying past Venus on July 11, 2020, the WISPR instrument onboard Parker Solar Probe detected a bright rim around the edge of the planet that may be nightglow. The prominent dark feature in the center of the image is Aphrodite Terra, the largest highland region on the Venusian surface. Bright streaks in WISPR, such as the ones seen here, are typically caused by a combination of cosmic rays, sunlight reflected by grains of space dust, and particles of material expelled from the spacecraft’s structures after impact with those dust grains. The number of streaks varies along the orbit or when the spacecraft is traveling at different speeds, and scientists are still in discussion about the specific origins of the streaks here. The dark spot appearing on the lower portion of Venus is an artifact from the WISPR instrument.
