Once these people achieved 4 healthy behaviors, eating at least 5 fruits and vegetables daily, exercising at least 2.5 hours per week, maintaining their Body Mass Index (BMI) between 18.5 and 30 kg/m, and not smoking, investigators saw a 35% reduction in CVD incidence and a 40% reduction in mortality compared to people with less healthy lifestyles.
Writing in the study, Dana E. King, MD, MS, states, “The potential public health benefit from adopting a healthier lifestyle in middle age is substantial. The current study demonstrated that adopting four modest healthy habits considerably lowers the risk of cardiovascular disease and mortality in relatively short-term 4-year follow up period. The findings emphasize that making the necessary changes to adhere to a healthy lifestyle is extremely worthwhile, and that middle-age is not too late to act.”
Starting in 1987 to 1989, 15,792 men and women ages 45 to 64 years participated in the Atherosclerosis Risk in Communities Study (ARIC) in four communities across the United States. This was designed to investigate the origin and progression of various atherosclerotic diseases. Follow up visits every three years through the end of 1998 included an interval medical history, weight, height, diet questionnaire, updated smoking history and current participation in sports and leisure exercise.
There were three key findings from the study – first, the benefit of switching to a healthy lifestyle past age 45 became evident even in the 4-year, short-term follow up; second, the beneficial impact of the changes occurred despite the relatively modest changes in health habits; and third, the healthy lifestyle was beneficial when compared to all persons with three or fewer healthy habits, not just in comparison to people with none or one habit. People adopting only three healthy habits experienced lower mortality but not fewer CVD events over the same period.
The authors found that only 8.5% of middle-aged adults practice these four behaviors and only 8.4% newly adopt such a lifestyle past age 45. Further, men, African-Americans, and individuals with less than college education, lower income, or a history of hypertension or diabetes are less likely to adopt a healthy lifestyle past age 45, and are therefore at greater risk of mortality and cardiovascular disease.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
