Sudden infant death syndrome (SIDS) is the leading reason given for death among infants one month to one year old. Studies have shown that sharing a bed with parents who smoke increases the risk of SIDS. A study in the July issue of The Journal of Pediatrics found a relationship between SIDS and bedsharing among infants less than 11 weeks old, even if parents are non-smokers.
David Tappin, MD, MPH and colleagues from University of Glasgow and Ecob Consulting evaluated 123 cases of SIDS in Scotland between 1996 and 2000. The parents of these infants provided information about the babys exposure to smoking, the parents routine infant-care practices, and the day or night of their infants death. The researchers found that 90% of the babies died while sleeping at night. Only 11% of the infants were reported to routinely sleep in their parents bed. 52% of the babies, however, had shared a bed/cot/couch or other surface at some point during the day or night that they died; of these, 87% were found in their parents beds.
A relationship exists between SIDS, bedsharing, couchsharing, and the location of the infants when they died; this association is magnified when the babies are less than 11 weeks old, regardless of how long they shared a sleep surface, their proximity to parents, their location in the bed, or their exposure to smoke. 72% of the infants found in their parents bed and 57% of the infants who shared a couch when they died were less than 11 weeks old. In this study, sleeping in a separate room did not increase the risk of SIDS, unless the parents were smokers.

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...
