As Americans waistlines continue to expand, contributing to a burgeoning epidemic of type 2 diabetes, the scientific jury is in and the verdict is clear: weight loss and increased physical activity is directly related to improved diabetes control. To help Americans fight the dramatic increase in type 2 diabetes, Joslin Diabetes Center has crafted new nutrition and physical activity guidelines for overweight and obese individuals with type 2 diabetes and those at risk for developing diabetes (pre-diabetes).
"Since obesity doesnt seem to be slowing down and the complications of diabetes are so serious, we were especially alarmed about the health of the American public. We felt the best way to impact the largest number of people was to strengthen our nutrition guidelines," said James L. Rosenzweig, M.D, head of Joslins clinical guidelines committee. The team of physicians, dietitians, exercise physiologists and educators spent months reviewing the scientific literature to draw up new guidelines. "The search was on for guidelines that would improve insulin sensitivity, cardiovascular health and reduce body fat. And most importantly, we wanted to deliver a plan that makes clear what people need to do to achieve their goals," said Dr. Rosenzweig, who also is Director of Joslins Disease Management Program and Assistant Professor of Medicine at Harvard Medical School.
The new guidelines recommend approximately 40 percent of a persons daily calories come from carbohydrates; 20 to 30 percent from protein (unless the person has kidney disease); 30-35 percent come from fat, (mostly mono- and polyunsaturated fats); and at least 20-35 grams of fiber. To initiate and continue weight reduction, a modest goal of one pound every one to two weeks is advised by reducing daily caloric intake by 250 to 500 calories. Total daily calories should not be less than 1,000 to 1,200 for women and 1,200 to 1,600 for men. A target of 60 to 90 minutes of modest intensity physical activity most days of the week with a minimum of 150-175 minutes/week is encouraged and should include cardiovascular, stretching and resistance activities to maintain or increase lean body mass.

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...
