The ’90s supermodel Christy Turlington, 53, and her husband Ed Burns, 54, don’t pose often with their two children. But this weekend the 53-year-old beauty and 54-year-old filmmaker were spotted with their teenage children while in Greece; they have daughter Grace, 18, and son Finn, 16. The family was enjoying dinner at a restaurant in Greece called The Island when they posed with several employees handing them coffee table books. With teens: Nineties supermodel Christy Turlington, 53, was spotted with her grown children while in Greece this weekend with husband Ed Burns, 54. The beauty and filmmaker have two children together: daughter Grace, 18, and son Finn, 16 Christy wore a black and white dress with black sandals as she pulled her hair back. The beautiful princess Grace is wearing a black and white mini dress that slips off the shoulders like she wears in black sandals and has her hair back. She added cute red earrings. Son Finn wore a pink striped polo shirt with dark tr

Dinosaurs have captured people’s imaginations more than any other ancient creature. These reptiles – some big, some small; several carnivores and other herbivores – rose and dominated the world’s landscapes for more than 135 million years during the period known as the Mesozoic. Today, dinosaur fossils can be found in many parts of the world, contained in a succession of rocks. It is a series of rock strata or units in chronological order. South Africa and the main Karoo Basin in Lesotho, for example, contain many dinosaur fossils in a succession of rocks formed between 220 million and 183 million years ago during the Late Triassic-Early Jurassic period. These ancient relics include body fossils (bones) and trace fossils, which are signs in ancient sediments in the form of footprints and burrows in the ground. Body fossils can help in re-creating ancient life forms, understanding what they looked like, their sizes, and even how they grew and evolved. The problem is, intact body

Toyota’s next SUV will hit local showrooms at the end of the year, with a choice of 2.0 liter petrol or hybrid power, and a possible deployment of three class models. 0 See 6 pictures What you’ve been waiting for Toyota Corolla Cross 2023 The small SUV has been given the go-ahead for sale in Australia, ahead of the arrival of the first showrooms before the end of this year. A recent Australian government certification document for the Corolla Cross lists three, previously confirmed powertrains for Toyota’s latest SUV: a 2.0-liter petrol engine with front-wheel drive, and a 2.0-liter hybrid system with front or all-wheel drive. The document hints at the availability of three model classes: an entry-level model with 17-inch wheels, a mid-spec variant with additional features, and a flagship class with 18-inch wheels and all available luxury features. Pricing hasn’t been confirmed, but if overseas pricing is a guide, expect the entry-level model to come in at around $35,000 a drive-away

(Photo: Toyota’s hydrogen fuel cell concept vehicle, 2019.) Main takeaways: High cost of catalyst. Platinum is the best catalyst for hydrogen fuel cells, but its scarcity makes it expensive. Find alternatives. The new method quickly identifies which alloy — a less expensive combination of platinum and another metal — is likely to achieve the best results in fuel cells. Cut costs. High-performance alloy catalysts could eventually make hydrogen fuel cell vehicles more affordable. A study led by UCLA researchers could help accelerate the use of hydrogen as an environmentally friendly energy source in transportation and other applications. The team developed a method to predict the potency and stability of platinum alloys – two key indicators of how they will perform as catalysts in hydrogen fuel cells. Then, using that techniq

Water boils a lot – whether it’s a cup of tea brewed in the kitchen or a power station that generates electricity. Any increase in the efficiency of this process will have a major impact on the overall amount of energy used for it each day. One such improvement could come with newly developed treatments for surfaces involved in heating and evaporating water. The treatment improves the two main parameters that determine the boiling process: heat transfer coefficient (HTC) and critical heat flux (CHF). Most of the time, there is a trade-off between the two – when one improves, the other worsens. After years of investigation, the research term behind this technique has found a way to improve both. “Both parameters are important, but raising the two parameters together is a bit tricky because they have an intrinsic trade-off,” said bioinformatics scientist Youngsup Song of the Lawrence Berkeley National Laboratory in California. “If we have a lot of bubbles on the boiling surface, that

Heart disease – the leading cause of death in the US – is so deadly in part because the heart, unlike other organs, cannot repair itself after injury. That is why tissue engineering, which ultimately includes the wholesale manufacture of whole human hearts for transplantation, is so important to the future of cardiac medicine. To build the human heart from the ground up, researchers needed to replicate the unique structures that make up the heart. This includes recreating the helical geometry, which creates a circular motion when the heart beats. It has long been theorized that this circular motion is essential for pumping blood at high volumes, but proving it is difficult, in part because creating hearts with different geometries and alignments is a challenge. Now, bioengineers from Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed the first biohybrid model of the human ventricle with helically aligned beating heart cells, and have shown that
