By Chelsea Whyte. They found that women receive more messages than men, and most of the messages sent on the service go to only a small fraction of users. The most popular person in the study was a year-old woman in New York who received messages during the month-long study period. For men, desirability peaked at around 50 years old, while for women it peaked at 18 and dropped steadily with age. The more education a man had had, the more desirable he was. But with women, an undergraduate degree was the most desirable level of education, and graduate degrees were linked to decreased desirability. Bruch and Newman saw that people of both genders are fairly self-aware, most commonly contacting others who had roughly the same ranking as their own. But a majority of the users — both male and female — still messaged some people who were out of their league. On average, these attempts to aim high were targetted at people who were 25 per cent more attractive than the user.

To support our nonprofit science journalism, please make a tax-deductible gift today. Timothy Sheahan, a virologist studying COVID, wishes he could keep pace with the growing torrent of new scientific papers about the disease and the novel coronavirus that causes it. But there are just too many—more than alone last week.
Where did we come from? Where are we going? Homo sapiens is the most successful, the most widespread and the most influential species ever to walk the Earth. In the blink of an evolutionary eye we have spread around the globe, taken control of Earth’s biological and mineral resources, transformed the environment, discovered the secrets of the universe and travelled into space.
Yet just 7 million years ago, we were just another species of great ape making a quiet living in the forests of East Africa. We do not know exactly what this ancestor was like, but it was no more likely than a chimpanzee or gorilla to sail across the ocean, write a symphony, invent a steam engine or ponder the meaning of existence. How did we get from there to here?
Human Origins recounts the most astonishing evolutionary tale ever told. Discover how our ancestors made the first tentative steps towards becoming human, how we lost our fur but gained language, fire and tools, how we strode out of Africa, invented farming and cities and ultimately created modern civilisation – perhaps the only one of its kind in the universe.
Meet your long-lost ancestors, the other humans who once shared the planet with us, and learn where the story might end.
Speed Dating with Scientists
In fact, it might be a matter of clicks. Those with a penchant for the old fashioned rituals of dating might choose to trade in the likes of Bumble, Tinder and Hinge for something a little more nostalgic. Enter, dating websites. Given that we’re currently under lockdown, we couldn’t find love at first sight in a bar even if we wanted to. Not only do dating sites actually offer users the option of specificity, something that is notably lacking on its app-based counterparts, but they generally offer a much wider pool of singletons.

8 best dating websites that prove there’s more to the world of digital romance than swiping right
Absolute dating also known as radiometric dating is based by the measurement of the content of specific radioactive isotopes of which the “half time” is known. Half time is the time needed for half of a given quantity of an isotope to decay in its byproducts. Comparing the quantity of the parent form and the byproduct will give a numerical value for the age of the material containing such isotopes.
25, — Scientists unveil a new crystalline material that reversibly changes color from yellow to red when absorbing water, paving the way for chemically.
Seventy years ago, American chemist Willard Libby devised an ingenious method for dating organic materials. His technique, known as carbon dating, revolutionized the field of archaeology. Now researchers could accurately calculate the age of any object made of organic materials by observing how much of a certain form of carbon remained, and then calculating backwards to determine when the plant or animal that the material came from had died. An isotope is a form of an element with a certain number of neutrons, which are the subatomic particles found in the nucleus of an atom that have no charge.
While the number of protons and electrons in an atom determine what element it is, the number of neutrons can vary widely between different atoms of the same element. Nearly 99 percent of all carbon on Earth is Carbon, meaning each atom has 12 neutrons in its nucleus. The shirt you’re wearing, the carbon dioxide you inhale and the animals and plants you eat are all formed mostly of Carbon Carbon is a stable isotope, meaning its amount in any material remains the same year-after-year, century-after-century.
Libby’s groundbreaking radiocarbon dating technique instead looked at a much more rare isotope of carbon: Carbon Unlike Carbon, this isotope of carbon is unstable, and its atoms decay into an isotope of nitrogen over a period of thousands of years. New Carbon is produced at a steady rate in Earth’s upper atmosphere, however, as the Sun’s rays strike nitrogen atoms.

Being on the shelf is only a problem if your shelf is dull. In fact, the older you get, the more interesting your shelf is likely to become and the harder it is to be coaxed off. And we are extending our own shelf-life everyday by staying fitter, healthier and more attractive for longer.
Women are no longer crying into their Chardonnay. Singles are more likely to be playing capoeira; dining at secret supper clubs; running with the Good Gym or digging up their home-grown kale. Which is why dating is such a problem. Why would you want to spend an excruciating hour getting to know a complete stranger when you could be enjoying ukulele karaoke with your mates or learning to make gin? T oday in Britain one in five heterosexual couples met online and a whopping 70 per cent of homosexual couples found their partner via the web.
But wait! New research is suggesting there could be very real problems with internet dating.

Carbon dating , also called radiocarbon dating , method of age determination that depends upon the decay to nitrogen of radiocarbon carbon Radiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle : it is absorbed from the air by green plants and then passed on to animals through the food chain. Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food.

We want politicians to get more involved and to recognize science as a priority for the well-being of citizens. Hence our actions and debates on topics connecting science with the political sphere. We want researchers to take action and explore beyond academia. Hence our projects related to employment, promotion, and our round tables about other approaches to science as new professions in the field.
We want citizens to become accomplices of the scientific process so that they understand that science has an impact on their lives, even when it is not obvious. Hence our actions in the field of citizen science. Contact us to see how we could help you. Stronger bonds create more powerful impact. Would you like to be part of the association? Our main objective is to raise awareness about the importance of science as a driver for change.
