Attempts to date cave paintings illustrate the difficulties of radiometric dating, and also show evidence of a young earth. A recent article about U-series dating of Paleolithic art in 11 caves in Spain 1 contained some frank discussions about the wild assumptions that had to be made to date the paintings, and raised some interesting questions about the scientifically accepted age of the Earth. Although Paleolithic art has nothing to do with evolution, the article does give us an opportunity to talk about dating techniques in general, and U-series dating in particular. Furthermore, the measured levels of uranium isotopes are nowhere near what the Old Earth model predicts. All dating methods depend upon measurement of something that varies with time. The simplest shape is a straight line, like the one below. Normally we look first at the horizontal axis of a graph like this because we know the TIME, and then look up Y at that point because we want to see what the value of Y is at that TIME.

Skip navigation! Story from TV Shows. The new-to-Netflix Australian docuseries Love on the Spectrum follows 11 young adults on the autism spectrum as they navigate romantic relationships, embark on first dates, and learn the ins and outs of love and dating. Some, like Jimmy and Sharnae, are already in love and planning to move in together; others, like Michael and Mark, are eager to find the one.
They were diverse in geographic and racial background but uniformly young, brash, attractive, and heterosexual. Now the diabolical series, which premiered in , has introduced a new element to the equation. Prior seasons of Are You the One? This new installment, though, serves a multi-layered purpose. The new season of Are You the One?
Like the hyper-branded festivities it coincided with, the show is a fascinating tonal mashup: The episodes that have aired thus far weave lessons about sexuality and gender and the politics of dating while queer into every element of the show. Cast members introduce themselves with backstories that account for upbringings spent in the closet or involve being the only publicly queer kid in middle school.
In this, Are You the One? On Are You the One? In an entertainment landscape that so clearly prized interpersonal chaos, the introduction of LGBTQ story lines was unsurprisingly salacious. When it was revealed to them, midway through production, their objective shifted from a putatively romantic pursuit to guessing which men had been tricking James all along.
Boy Meets Boy presented this as an intriguing plot development, but the show replicated the kind of dangerous guesswork queer people must undertake each day—for gay men like James, incorrectly identifying another man as gay could lead to consequences far more dire than losing a game show.

Netflix’s ‘Dating Around’ Is The Addictive Reality Series That We Should All Be Watching
Both Netflix and Hulu have a variety of dating shows that you can stream right now. With these transformations comes a slew of new dating programs that tend to be viewed when everyone else goes to bed. Here are a few more guilty pleasures to watch snuggled in your favorite blanket.
Uranium series dating techniques rely on the fact that radioactive uranium and thorium isotopes decay into a series of unstable, radioactive “daughter” isotopes; this process continues until a stable non-radioactive lead isotope is formed. The daughters have relatively short half-lives ranging from a few hundred thousand years down to only a few years. The “parent” isotopes have half-lives of several thousand million years.
This provides a dating range for the different uranium series of a few thousand years to , years. Uranium series have been used to date uranium-rich rocks, deep-sea sediments, shells, bones, and teeth, and to calculate the ages of ancient lake beds. The two types of uranium series dating techniques are daughter deficiency methods and daughter excess methods.
In daughter deficiency situations, the parent radioisotope is initially deposited by itself, without its daughter the isotope into which it decays present. Through time, the parent decays to the daughter until the two are in equilibrium equal amounts of each. The age of the deposit may be determined by measuring how much of the daughter has formed, providing that neither isotope has entered or exited the deposit after its initial formation.
Living mollusks and corals will only take up dissolved compounds such as isotopes of uranium, so they will contain no protactinium, which is insoluble. Protactinium begins to accumulate via the decay of U after the organism dies.

Uranium—thorium dating , also called thorium dating , uranium-series disequilibrium dating or uranium-series dating , is a radiometric dating technique established in the s which has been used since the s to determine the age of calcium carbonate materials such as speleothem or coral. Instead, it calculates an age from the degree to which secular equilibrium has been restored between the radioactive isotope thorium and its radioactive parent uranium within a sample.
Thorium is not soluble in natural water under conditions found at or near the surface of the earth, so materials grown in or from this water do not usually contain thorium. As time passes after such material has formed, uranium in the sample with a half-life of , years decays to thorium At secular equilibrium, the number of thorium decays per year within a sample is equal to the number of thorium produced, which also equals the number of uranium decays per year in the same sample.
In , John Joly , a professor of geology from the University of Dublin , found higher radium contents in deep sediments than in those of the continental shelf, and suspected that detrital sediments scavenged radium out of seawater.

While singles around the world have spent the last few months navigating their love lives on brand-new territory, it’s time to start getting back into the swing of things. For those who remember Netflix’s Dating Around , a strangely addictive dating show that aired in , the series became a fresh, no-frills take on the cringe-worthy reality dating trope. And as becomes a year obsessed with reality television—hello Love Is Blind and Too Hot To Handle —their extreme storylines often kept each shows idea of dating unrealistic.

Skyrocketing to one of Netflix’s top dating shows of , the low-key addictive series is back for season two, along with a new group of singles looking for their future ‘someone’. Below, you’ll find everything we know about Dating Around season two so far, from the release date to the cast members.
In each minute episode of Dating Around , one blind-dater is set up on five blind dates, which all occur at the same bar or restaurant and follows the person’s journey to finding ‘the one’. The first season of the series took place in New York City and featured a diverse cast of daters who were all across the board in age, sexual orientation, and ethnicity. And season two looks to do the same, except this time in New Orleans, Louisiana. For those interested in a new dating show full of drama, you won’t be disappointed.
In the first season, fans will remember a disaster date involving Gurki Basra, a year-old jewellery buyer, whose terrible date with Justin, a man who criticised Basra’s decision to get married after succumbing to pressure from her family, was called out by Basra and resulted in the designer choosing herself in the end.

The U-series laboratory focuses on development and application of U-series dating techniques to provide a robust chronological framework for palaeoclimatology, archaeology and human evolution. The U-series disequilibrium method is based on the radioactive decay of radionuclides within the naturally occurring decay chains. There are three such decay chains, each starts with an actinide nuclide U, U, Th having a long half live and ultimately ends with different a stable isotope of lead.
U-Th dating can be applied to secondary calcium carbonate formations like speleothems , travertine or corals. For dating e. Differential solubility between uranium and its long lived daughter isotope Th means that drip water in caves and calcite precipitates from this water e. Over time, there is ingrowth of Th from the radioactive decay of uranium until radioactive equilibrium is reached where all isotopes in the series are decaying at the same rate.
This method has a dating range up to about We use U-Th dating to obtain a chronology for stalagmites which are used for palaeoclimate research pdf , dating carbonate crusts on cave art to derive minimum age constraints for underlying art paper Hoffmann et al.
