Radiocarbon C 14 concentrations at a 43 parts-per-quadrillion level are measured by using saturated-absorption cavity ringdown spectroscopy by exciting radiocarbon-dioxide C 14 O 2 16 molecules at the 4. The ultimate sensitivity limits of molecular trace gas sensing are pushed down to attobar pressures using a comb-assisted absorption spectroscopy setup. Such a result represents the lowest pressure ever detected for a gas of simple molecules. The unique sensitivity, the wide dynamic range, the compactness, and the relatively low cost of this table-top setup open new perspectives for C 14 -tracing applications, such as radiocarbon dating, biomedicine, or environmental and earth sciences. The detection of other very rare molecules can be pursued as well thanks to the wide and continuous mid-IR spectral coverage of the described setup. Infrared spectroscopy can detect trace gases and potentially provide an alternative carbon dating technique.

This is Part 2. Part 1 is here. Often, the key to succeeding at something big is to break it into its tiniest pieces and focus on how to succeed at just one piece. When we examined procrastination , we talked about how a great achievement is just what a long series of unremarkable tasks looks like from far away. In the pixel post , we looked at a human life up close and saw that it was just an ordinary Wednesday, again and again and again—and that achieving life happiness was all about learning to be happy on a routine weekday.
I think the same idea applies to marriage. From afar, a great marriage is a sweeping love story, like a marriage in a book or a movie. To endure 20, days with another human being and do so happily, there are three key ingredients necessary:. But with certain friends, the time is so high-quality, so interesting, and so fun that they pass the Traffic Test.

Laser ablation has become a dominant technology for direct solid sampling in analytical chemistry. Laser ablation refers to the process in which an intense burst of energy delivered by a short laser pulse is used to sample remove a portion of a material. The advantages of laser-ablation chemical analysis include direct characterization of solids, no chemical procedures for dissolution, reduced risk of contamination or sample loss, analysis of very small samples not separable for solution analysis, and determination of spatial distributions of elemental composition.
Since then the word ablation has been adopted in the analytical community to describe the direct removal of material from samples of interest for subsequent chemical analysis. There are many excellent review papers related to the techniques presented here 3— However, since this column installment is meant to be an introduction to the field, rather than an exhaustive review, they could not all be included here.
For ablation to occur, energy absorption is needed.
How to Pick Your Life Partner – Part 2
I wanted, after Biophilia ‘s crowning glory, a sparky fresh start. I wanted harsh beats, crackling energy, new ideas. What I got is a mortuary slab of cold, heavy pain, forensically picked over. But life happens to you, doesn’t it? That sounds melodramatic, but Vulnicura is so intimate in its agonies, so clinical in its dissection that your brain, listening, tries to hide from it as if the pain was its own; and, as if the pain was its own, cannot.

Online dating services began to pop up with the growing popularity of the Internet, following created Match. Karla Moore, an Atlanta-based dating and relationships expert, explained that the reason for this influx is the growing amount of people that remain single into adulthood. With this many singles, it should not surprise us that technologies have been created to support our biological need to find love. Regarding apps like Tinder and Bumble, Moore said the key to avoid disappointment when meeting with another person is making sure to be on the same wavelength.
In the same breath, a person can meet very suitable singles on Tinder. She has been with her boyfriend, whom she met through the app, for over a year. Yund said she was hesitant at first about the date, but she ended up having a great time and soon went on more dates with the same person, eventually leading to a great relationship. As for those who want to pursue a relationship on such an app, Yund advises to have fun, but to always use caution. For millennials, it is a normal to find significant others on popular dating apps like Tinder.

The 8 features a gorgeous glass back compared to the previous aluminum of the 7 , a better camera with faster shutter speeds, and our beloved portrait mode.

New technologies to predict spoilage time could slash the massive waste between farm and fork. In August , a can of Great Value peas joined the nonperishables in my pantry, one of several panic purchases as Hurricane Irene barreled toward my home on the northeast US coast. But the emergency passed, and the can, with its unassuming blue-on-white outline font, remains on my shelf seven years later.

Small-molecule fluorescent probes have become powerful tools for using light to advance the study of cell biology, discover new drugs, detect environmental contaminants, and further the detection of cancer. These applications correlate with the expansion of the fluorescent probe research community — small in the late 20 th century, now a collection of more than a hundred research groups world-wide.
This expansion required the entry of adventurous scientists from many other fields.

This paper aims to provide an overview concerning the optically stimulated luminescence OSL dating method and its applications for geomorphological research in France. An outline of the general physical principles of luminescence dating is given. A case study of fluvial sands from the lower terrace of the Moselle valley is then presented to describe the range of field and laboratory procedures required for successful luminescence dating.
The paper also reviews the place of OSL dating in geomorphological research in France and assesses its potential for further research, by focusing on the diversity of sedimentary environments and topics to which it can be usefully applied. Hence it underlines the increasing importance of the method to geomorphological research, especially by contributing to the development of quantitative geomorphology. They are now largely used to date not only palaeontological or organic remains, but also minerals that characterise detrital clastic sedimentary material.
The most common methods applied to minerals are cosmogenic radionuclides, electron spin resonance ESR and luminescence techniques. The latter were first applied to burned minerals from archaeological artefacts [thermoluminescence TL method]. Improvements of this technique led to the development, for more than twenty years, of the optical dating method [commonly referred to as Optically Stimuled Luminescence OSL ] which is now applied to sediments from various origins Wintle, The aim of this paper is to provide people involved in geomorphological research a global overview about the principles and procedures of optical dating, from the field sampling to the age interpretation.
Most of the publications actually focus on one part of either the method e.
