The findings strengthen the idea that certain parental practices throughout high school and perhaps college could be used to curb high-risk drinking in older adolescents. Underage drinking is linked to a number of negative outcomes in this group, including suicide, high-risk sexual activity and an increased chance of alcohol dependence.
Researchers from the Center for Substance Abuse Research at the University of Maryland College Park, Maryland, USA interviewed over 1,200 students for the research, which forms part of the College Life Study. This is an ongoing, longitudinal, prospective investigation of health-risk behaviors in college students, including alcohol and other drug use.
The team assessed parental monitoring and student alcohol consumption (in drinks per day) in high school using surveys in the summer before the students attended a large public university in the mid-Atlantic. Students were followed up with a personal interview in their first college year to assess their alcohol consumption over the past year.
Higher levels of parental supervision were associated with lower levels of high-school drinking, independent of sex, race and religiosity. Although parental monitoring did not directly influence alcohol consumption in college, there was evidence that high school drinking mediates the relationship between the two factors. Thus, the higher the drinking in high school, the higher the drinking in college. The authors point out that these results call into question the opinion of many parents who think “responsible drinking” should begin in high school. Further research is needed to explore the extent and type of parental supervision that may reduce students’ drinking in college.
The authors write: “In summary, the transition to college marks a high-risk period for escalation of alcohol consumption. Parents and prevention practitioners can benefit from evidence that points to specific parenting practices that might help reduce the risk for heavy drinking, while at the same time allow for appropriate levels of autonomy that are critical for young adult development”

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...
