China’s scientists are using a variety of approaches to boost crop yields and limit environmental damage, say Fusuo Zhang, Xinping Chen and Peter Vitousek. For the past two decades, commentators have hailed genetically modified GM crops as the magic bullet that will solve the world’s food crisis. Yet obtaining the drastically bigger yields needed to feed a growing and increasingly wealthy global population — without further depleting soils, destroying natural habitats and polluting air and water — will demand an all-embracing approach. China is taking steps towards such a strategy, and so offers an extraordinary laboratory for the rest of the world. The country has little spare land, and water shortages are reaching crisis levels in some areas.

Gender Differences in Receptivity to Sexual Offers: A New Research Prototype

O nly eating and sleeping could be said to have a stronger grasp on the steering wheel of our daily behaviour than the thing in our heads that is constantly urging us to find love and have sex. But even an insatiable appetite and overwhelming tiredness are no match for the sudden arrival or breakdown of pure romantic love, or unbridled sexual lust. These are, after all, the states of mind that inspired every one of our direct ancestors to relentlessly pursue love and sex until they succeeded at least once in getting their genes into a new generation.

The love experiment: A 40-day dating challenge

Washington : Researchers have, for the first time, successfully determined the age of a Martian rock – with experiments being performed on the Red Planet. The work, led by geochemist Ken Farley of the California Institute of Technology Caltech , would not only help in understanding the geologic history of Mars but also aid in the search for evidence of ancient life on the planet.

In March, Curiosity drilled holes into the mudstone and collected powdered rock samples from two locations about three meters apart. Once the rock samples were drilled, Curiosity’s robotic arm delivered the rock powder to the Sample Analysis on Mars SAM instrument, where it was used for a variety of chemical analyses, including the geochronology-or rock dating-techniques.

One technique, potassium-argon dating, determines the age of a rock sample by measuring how much argon gas it contains. Over time, atoms of the radioactive form of potassium-an isotope called potassiumwill decay within a rock to spontaneously form stable atoms of argon

To work through their individual relationship issues, Jessica Walsh the romantic , 26, partner at design firm Sagmeister and Walsh, and Timothy Goodman the commitment-phobe , 32, independent designer, illustrator and art director, decided to go through the motions of being in a relationship after years spent chasing love.

Six Feet Of Separation: Your Stories Of Love And Dating During COVID-19

In a little more than a year on the Red Planet, the mobile Mars Science Laboratory has determined the age of a Martian rock, found evidence the planet could have sustained microbial life, taken the first readings of radiation on the surface, and shown how natural erosion could reveal the building blocks of life. Curiosity team members presented these results and more from Curiosity in six papers published online today by Science Express and in talks at the Fall Meeting of the American Geophysical Union in San Francisco.

The second rock Curiosity drilled for a sample on Mars, which scientists nicknamed “Cumberland,” is the first ever to be dated from an analysis of its mineral ingredients while it sits on another planet. A report by Kenneth Farley of the California Institute of Technology in Pasadena, and co-authors, estimates the age of Cumberland at 3. This is in the range of earlier estimates for rocks in Gale Crater, where Curiosity is working.

The old adage says that it takes 40 days to change a habit—could the same be said for love? So they agreed to date each other for 40 days, record their experiences in questionnaires, photographs, videos, texts, and artworks, and post the material on a website they would create for this purpose.

Research exploiting data on classic offline couple formation has confirmed predictions from evolutionary psychology in a sense that males attach more value to attractiveness and women attach more value to earnings potential. We examine whether these human partner preferences survive in a context of fewer search and social frictions.

We do this by means of a field experiment on the mobile dating app Tinder, which takes a central place in contemporary couple formation. Thirty-two fictitious Tinder profiles that randomly differ in job status and job prestige are evaluated by 4, other, real users.

Two good friends with opposite relationship problems found themselves single at the same time. As an experiment, they dated for 40 days.

December 11, Although researchers have determined the ages of rocks from other planetary bodies, the actual experiments—like analyzing meteorites and moon rocks—have always been done on Earth. Now, for the first time, researchers have successfully determined the age of a Martian rock—with experiments performed on Mars. The work, led by geochemist Ken Farley of the California Institute of Technology Caltech , could not only help in understanding the geologic history of Mars but also aid in the search for evidence of ancient life on the planet.

However, shortly before the rover left Earth in , NASA’s participating scientist program asked researchers from all over the world to submit new ideas for experiments that could be performed with the MSL’s already-designed instruments. Farley, W. Keck Foundation Professor of Geochemistry and one of the 29 selected participating scientists, submitted a proposal that outlined a set of techniques similar to those already used for dating rocks on Earth, to determine the age of rocks on Mars.

Take a small crystal of garnet, a common mineral with built-in chronometers and uncommon properties due to its crystalline structure, study it, and suddenly you have insights on large-scale processes like plate subduction, timing and duration of metamorphism, seismicity, and more. The authors in this issue, assembled by guest editors Ethan F. Baxter Boston University , Mark J. Caddick Virginia Tech , and Jay J. Ague Yale University , take us on a whirlwind tour of the mantle and crust, and inform us on the technological applications and the place in history of this beloved mineral.

We review the in situ geochronology experiments conducted by the Mars Science Laboratory mission’s Curiosity rover to understand when the Gale Crater rocks formed, underwent alteration, and became exposed to cosmogenic radiation.

The sedimentary rocks underwent fluid-moderated alteration 2 Gyr later, which may mark the closure of aqueous activity at Gale Crater. Over the past several million years, wind-driven processes have dominated, denuding the surfaces by scarp retreat.

How does a tree know it is autumn? How is climate change affecting when the leaves of Swedish deciduous trees turn colour in the autumn? Are there variations in autumn leaf development between different tree species and in different locations in Sweden? Is it possible to study autumn using satellite images? Climate change is impacting when the growing season in nature begins in the spring and when it ends in the autumn.

Previous research has shown that changes to the climate seem to be affecting different species of trees in different ways, and that the changes vary in different regions. Although this is an important issue that is fundamentally affecting the ecosystem, little is known about how climate change affects the autumn leaf development of different tree species. Therefore the Autumn Experiment was an important experiment.

Altogether over 10, pupils sent in reports on more than 2, trees from different locations in Sweden. Using the observations, researchers could examine the differences between various tree species and regions. The Autumn Experiment 0 reviews. Location Sweden.
