"Workplaces, restaurants, homes and even bars are mostly smoke-free, but cars have been forgotten," says Emara Nabi-Burza, MBBS, MS, the study's lead author. "Smoking in cars is not safe for motorists and nonsmokers – especially children, who have no way to avoid tobacco smoke exposure in their parent's car. Now that we know the magnitude of the problem, pediatricians and the public can act to help these children." Nabi-Burza is an investigator with the Center for Child and Adolescent Health Policy at MGHfC.
The authors write that tobacco smoke can contribute to an increased risk of respiratory infections, cancer and even death in children. Homes have traditionally been considered the main indoor source of smoke exposure for children, but recent studies have found elevated levels of tobacco smoke contaminants in cars, says Nabi-Burza, noting that children may spend a considerable amount of time in their family's car.
In the study, researchers interviewed 795 smoking parents about their car-smoking policy and behavior, including whether they exposed their children to tobacco smoke in their cars. The participants were interviewed while exiting from their child's doctors' office in one of 10 pediatric practices in eight states. Seventy-three percent of the parents admitted that someone had smoked in their car in the past 3 months. Of the 562 parents who did not have a smoke-free car policy, 48 percent smoked in the car when their children were present. Most parents adopted a "strictly enforced" smoke-free policy in their homes, but only 24 percent of parents had a strictly enforced smoke-free policy for their cars.
Only about one-fifth of the parents reported being asked by a pediatric health care provider about their smoking status. Few of the parents who smoked (12 percent) were advised by the provider to avoid smoking in their cars. This is the first known study to examine the rates at which pediatricians address smoking in cars; and due to the low percentage of parents counseled on this issue, the authors conclude that pediatricians should address tobacco use with parents and encourage them to have strict smoke-free home and car policies to help reduce tobacco smoke exposure of children.
Because of their role in advocating for children's health, Nabi-Burza says pediatricians have the unique opportunity to counsel parents on creating a strict smoke-free car policy.
"An infant strapped in a car seat cannot advocate effectively for herself in the face of parental tobacco addiction. The pediatrician can help the parent set a no-smoking policy in the car," says Jonathan P. Winickoff, MD, MPH, the study's senior author. He is an associate professor of Pediatrics and Nabi-Burza is a research associate in Pediatrics at Harvard Medical School.

Für die MICADO-Kamera, das Instrument mit dem das European Extremely Large Telescope (E-ELT) seine ersten Bilder machen wird, beginnt eine neue Phase: In einer gemeinsamen Absichtserklärung (Memorandum of Understanding) auf der „Kick-off“-Konferenz in Wien bestätigten die Partner in Deutschland, Frankreich, den Niederlanden, Österreich und Italien ihre Teilnahme am Projekt. Zwei Wochen zuvor, am 18. September, hatten das Konsortium und die Europäische Südsternwarte (ESO), die das Teleskop baut, den entsprechenden Kooperationsvertrag unterzeichnet. Nach diesen Meilensteinen tritt das Projekt nun in die Designphase ein.
Als erste, dedizierte Kamera für das E-ELT wird MICADO beugungsbegrenzte Abbildungen bei Nah-Infrarot-Wellenlängen (Wärmestrahlung) mit dem Riesenteleskop...
The MICADO camera, a first light instrument for the European Extremely Large Telescope (E-ELT), has entered a new phase in the project: by agreeing to a Memorandum of Understanding, the partners in Germany, France, the Netherlands, Austria, and Italy, have all confirmed their participation. Following this milestone, the project's transition into its preliminary design phase was approved at a kick-off meeting held in Vienna. Two weeks earlier, on September 18, the consortium and the European Southern Observatory (ESO), which is building the telescope, have signed the corresponding collaboration agreement.
As the first dedicated camera for the E-ELT, MICADO will equip the giant telescope with a capability for diffraction-limited imaging at near-infrared...
Self-driving cars will be on our streets in the foreseeable future. In Graz, research is currently dedicated to an innovative driver assistance system that takes over control if there is a danger of collision. It was nature that inspired Dr Manfred Hartbauer from the Institute of Zoology at the University of Graz: in dangerous traffic situations, migratory locusts react around ten times faster than humans. Working together with an interdisciplinary team, Hartbauer is investigating an affordable collision detector that is equipped with artificial locust eyes and can recognise potential crashes in time, during both day and night.

Selbstfahrende Autos könnten in absehbarer Zukunft auf unseren Straßen unterwegs sein. Ein innovativer Fahrzeugassistent, der bei Kollisionsgefahr das Steuer übernimmt, wird gerade in Graz erforscht. Manfred Hartbauer vom Institut für Zoologie der Karl-Franzens-Universität hat sich die Basis dafür in der Natur abgeschaut: Wanderheuschrecken können in brenzligen Verkehrssituationen etwa zehnmal schneller reagieren als Menschen. In Zusammenarbeit mit einem interdisziplinären Team erforscht er einen kostengünstigen Kollisionsdetektor, der mit künstlichen Heuschrecken-Augen ausgestattet ist und drohende Zusammenstöße bei Tag und Nacht rechtzeitig erkennen kann.
Ein interdisziplinäres Forscherteam hat den ersten Prototyp eines Miniatur-Teilchenbeschleunigers gebaut, der mit Terahertz- anstelle von Hochfrequenz-Strahlung funktioniert. Ein einzelnes Beschleunigungsmodul ist dabei nur 1,5 Zentimeter lang und einen Millimeter dünn. Die Terahertz-Technik verspricht eine Miniaturisierung um mindestens den Faktor 100, wie die Wissenschaftler um DESY-Forscher Franz Kärtner vom Center for Free-Electron Laser Science (CFEL) betonen. Sie stellen ihren Prototyp im Fachblatt „Nature Communications“ vor. Das CFEL ist eine Kooperation von DESY, Universität Hamburg und Max-Planck-Gesellschaft.
Für kompakte Terahertz-Beschleuniger sehen die Autoren zahlreiche Anwendungen in Materialforschung, Medizin und Teilchenphysik sowie bei Röntgenlasern....
