Scientists and journalists, Glyptodontidae, and new dating of archaeological material from northeastern Brazil. The present issue of the Annals of the Brazilian Academy of Sciences AABC has an interesting contribution about the interaction of journalists and scientists in Brazil. Communicating science to the public is quite a demanding task, but in recent years this activity has been worldwide regarded as an essential tool to establish stronger connections between the scientific community and the society e. Efforts in that direction have been put forward in several countries with overall positive results e. There is no question that Brazilian scientists should take this task very seriously, particularly in the troubled waters that researchers will have to face in the years to come. The good news is that in the country there is a growing trend of collaboration between scientists and media. Since , for example, the National Council for Scientific and Technological Development CNPq , which is the main funding agency of the country, has started to encourage researchers to list their public communication activities in the open access platform Plataforma Lattes , where all curricula of those who apply for grants are mandatorily made public.

Chronological dating, or simply dating, is the process of attributing to an object or event a date Many disciplines of archaeological science are concerned with dating evidence, but in practice several different dating techniques must be.
Subscriber Account active since. Well, yes: There’s no reason to fly blind. That means thousands and thousands of study subjects have made all kinds of dating mistakes so that you and I don’t have to. How do you make that relationship function? You don’t know unless you try. No, what we’re saying here has a lot to do with point 1: You want a fun person that likes fun? Show off how much fun you have, and how much fun other people have with you.
To really nail it, get right in the middle and touch someone else — but only on the upper arm. The study also found that women were more attracted to men when other women in the photo were smiling at him, but proceed with caution here. The researchers also recommend selfies with genuine smiles , the kind that crinkles up your eye at the edges, and a little head tilt. Women looking for men can wear read for bonus points. This study has some pretty hefty limitations: All 1, dates were between opposite-sex pairs of Standford graduate students.
First dates are definitely nerve-wracking, but that’s doesn’t mean you have to let anxiety get the better of you. A study with possibly the most resonant title of all time — “Adult attachment and dating strategies: How do insecure people attract mates?
Dating the age of humans

Not according to a study of more than 1 million interactions on a dating website published this week in the Proceedings of the National Academy of Sciences.
Amini started off with the basics, working part time on what would become a full-fledged dating-app startup. His work as a rocket scientist gave.
Radiocarbon dating is set to become more accurate than ever after an international team of scientists improved the technique for assessing the age of historical objects. The team of researchers at the Universities of Sheffield, Belfast, Bristol, Glasgow, Oxford, St Andrews and Historic England, plus international colleagues, used measurements from almost 15, samples from objects dating back as far as 60, years ago, as part of a seven-year project.
They used the measurements to create new international radiocarbon calibration IntCal curves, which are fundamental across the scientific spectrum for accurately dating artefacts and making predictions about the future. Radiocarbon dating is vital to fields such as archaeology and geoscience to date everything from the oldest modern human bones to historic climate patterns. Archaeologists can use that knowledge to restore historic monuments or study the demise of the Neanderthals, while geoscientists on the Intergovernmental Panel on Climate Change IPCC , rely upon the curves to find out about what the climate was like in the past to better understand and prepare for future changes.
As we improve the calibration curve, we learn more about our history. The IntCal calibration curves are key to helping answer big questions about the environment and our place within it. The team of researchers have developed three curves dependent upon where the object to be dated is found. Developments in the field have made it possible to truly advance our understanding.
I look forward to seeing what new insights into our past these recalculated radiocarbon timescales provide. The previous radiocarbon calibration curves developed over the past 50 years, were heavily reliant upon measurements taken from chunks of wood covering 10 to 20 years big enough to be tested for radiocarbon. Advances in radiocarbon testing mean the updated curves instead use tiny samples, such as tree-rings covering just single years, that provide previously impossible precision and detail in the new calibration curves.
Additionally, improvements in understanding of the carbon cycle have meant the curves have now been extended all the way to the limit of the radiocarbon technique 55, years ago.

One might think that a scientist, recognizing firsthand the peculiar hardships of his profession, would look anywhere but to a colleague as a potential life partner, and instead seek out someone whose career would bring fewer pressures to a relationship. In many ways, such scientists say, the success of their relationships is owed to the fact that their partners share the very second challenges.
At the same time, the limited research that has been done on dual-career science couples by Rayman and others clearly shows the potential scientific impact the demands of a science career can have on marital and family relationships. Additionally, the books are also cause for concern for universities, scientist, and research consortia, all of which rely on a well-trained and second scientific and technical work force.
The purpose of the committee is to develop workplace policies that accommodate family needs. For the most part, however, tips, programs, and policies in the world of science are far from conducive to a trouble-free coexistence of career and family, says Rayman. After earning Ph. Research shows that a wife will often follow her husband, and, in doing so, accept a less-than-satisfying position as a trade-scientist for staying together.

The Age of DNA-Based Dating Is Here
You may say we kind of geek out about things. Whatever, geeks are awesome. But sometimes, awesome can use a bit of assistance in the dating department. Thanks to geeks, that’s how.
Physical science is helping archaeologists close in on the real answers With the help of new physical and chemical dating methods, scientists are finally.
Jump to navigation. In a series of three papers , the team of researchers have recalculated and adjusted the international radiocarbon calibration, or IntCal, curves, which are tools used by researchers across many disciplines to accurately date artifacts and make predictions about the future. Radiocarbon dating works by assessing the ratio of different kinds, or isotopes, of carbon atoms in an object. The method allows archaeologists and environmental scientists to date everything from the oldest modern human bones to historic climate patterns.
The research team used measurements from over 15, samples from objects dating back as far as 60, years ago, as part of a seven-year project. Archaeologists can use the curves to date ancient monuments or study the demise of the Neanderthals, while geoscientists on the Intergovernmental Panel on Climate Change rely upon the curves to find out about what the climate was like in the past to better understand and prepare for future changes. The team of researchers has developed three curves, based upon where the object to be dated is found — IntCal20 for the northern hemisphere, SHCal20 for the southern hemisphere and Marine20 for the world’s oceans.
The new curves are published in the journal Radiocarbon, which is published by the University of Arizona in partnership with Cambridge University Press. The journal began in and has been published by UArizona since IntCal has become an essential tool for accurate calibration of radiocarbon dates and gradually improved over the last 35 years.
How Do Scientists Determine the Age of Dinosaur Bones?
Researchers use data from tree rings, sediment layers and other samples to calibrate the process of carbon dating. Radiocarbon dating — a key tool used for determining the age of prehistoric samples — is about to get a major update. For the first time in seven years, the technique is due to be recalibrated using a slew of new data from around the world. The work combines thousands of data points from tree rings, lake and ocean sediments, corals and stalagmites, among other features, and extends the time frame for radiocarbon dating back to 55, years ago — 5, years further than the last calibration update in Archaeologists are downright giddy.
Valentine’s Day is typically a hard time for many, namely those who object to the commercialised nature and emphasis on public displays of affection, those who are presently single but would rather not be and find the whole ethos of the day offensive, or some combination of the two. But there is a simple solution to both of these problems: date a scientist.
Scientists are highly educated people with decent career prospects, but are also rarely associated with a fondness for romance and passion or any other emotional state so are likely to be apathetic towards Valentine’s Day. Ergo, scientists are the ideal partners. But how does one go about finding, courting and eventually establishing a solid relationship with an elusive and complex scientist?
It’s not easy; they are not like other, more simple humans. But what follows is a brief guide for those wishing to make the attempt to woo a scientist.
