Allergists warn e-smokers of unknown risks
Caveat emptor – or "buyer beware" holds true when it comes to the unknown health effects of e-cigarettes. An article in the June issue of Annals of Allergy, Asthma & Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI), examines risks, including the ongoing dependence on nicotine and the dual use of e-cigarettes and regular cigarettes.
The article examines the idea that one of the initial "health benefits" proposed by e-cigarettes makers was that it would help those who smoke cigarettes cut back. The authors say that theory hasn't been proven, and there's no evidence to support the claims.
"Despite the apparent optimism surrounding e-cigarettes and their purported therapeutic role in smoking cessation, there just simply is not enough evidence to suggest that consumers should use e-cigarettes for this purpose." said allergist Andrew Nickels, MD, lead author, ACAAI member, Mayo Clinic Division of Allergy and Immunology.
Another cause for concern is that when people use e-cigarettes in public and still smoke regular cigarettes at home, they continue to expose children and asthma sufferers in the household to dangerous second hand smoke.
"Dual use of both e-cigarettes and regular cigarettes carries the risk of secondhand smoke exposure, causing worsening respiratory effects on children and asthma sufferers. It also promotes ongoing nicotine dependence," said Chitra Dinakar, MD, co-author, ACAAI fellow and Professor of Pediatrics, Children's Mercy Hospitals.
Because e-cigarettes are fairly new, there could be other long-term health complications that have yet to be discovered. Results of long-term exposure to such substances are unknown. Due to the lack of production oversight, most consumers don't know what's in the e-cigarettes they buy. The US Food and Drug Administration admits that the safety and efficacy of e-cigarettes hasn't been fully studied, and consumers have no way of knowing if e-cigarettes are safe for their intended use.
Organizations like ACAAI are advocating for enhanced scrutiny and regulation by the FDA. The ACAAI's position statement on e-cigarettes recognizes that nicotine delivered by any mechanism represents a drug exposure, and that vaporization instruments are a drug delivery system, both of which are within the Federal Drug Agency's scope of regulation.
Inhaling irritants such as smoke and vapors has an impact on the lungs, whether it is mild or severe. And irritants can cause asthma attacks in some individuals. These attacks are responsible for some of the 4,000 asthma-related deaths per year.

The ACAAI is a professional medical organization of more than 6,000 allergists-immunologists and allied health professionals, headquartered in Arlington Heights, Ill. The College fosters a culture of collaboration and congeniality in which its members work together and with others toward the common goals of patient care, education, advocacy and research. ACAAI allergists are board-certified physicians trained to diagnose allergies and asthma, administer immunotherapy, and provide patients with the best treatment outcomes.

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
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...
