Sea robins are fish with ‘the wings of a bird and multiple legs like a crab’
kra10 cc
Some types of sea robins, a peculiar bottom-dwelling ocean fish, use taste bud-covered legs to sense and dig up prey along the seafloor, according to new research.

Sea robins are so adept at rooting out prey as they walk along the ocean floor on their six leglike appendages that other fish follow them around in the hope of snagging some freshly uncovered prey themselves, said the authors of two new studies published Thursday in the journal Current Biology.

David Kingsley, coauthor of both studies, first came across the fish in the summer of 2016 after giving a seminar at the Marine Biological Laboratory in Woods Hole, Massachusetts. Kingsley is the Rudy J. and Daphne Donohue Munzer Professor in the department of developmental biology at Stanford University’s School of Medicine.

Before leaving to catch a flight, Kingsley stopped at a small public aquarium, where he spied sea robins and their delicate fins, which resemble the feathery wings of a bird, as well as leglike appendages.

“The sea robins on display completely spun my head around because they had the body of a fish, the wings of a bird, and multiple legs like a crab,” Kingsley said in an email.
“I’d never seen a fish that looked like it was made of body parts from many different types of animals.”
Kingsley and his colleagues decided to study sea robins in a lab setting, uncovering a wealth of surprises, including the differences between sea robin species and the genetics responsible for their unusual traits, such as leglike fins that have evolved so that they largely function as sensory organs.

The findings of the study team’s new research show how evolution leads to complex adaptations in specific environments, such as the ability of sea robins to be able to “taste” prey using their quickly scurrying and highly sensitive appendages.

7 simple secrets to eating the Mediterranean way
кракен даркнет
What if “diet” wasn’t a dirty word?

During Suzy Karadsheh’s childhood in Port Said, Egypt, diet culture was nonexistent.

“My parents emphasized joy at the table, rather than anything else,” Karadsheh said. “I grew up with Mediterranean lifestyle principles that celebrate eating with the seasons, eating mostly whole foods and above all else, sharing.”

But when Karadsheh moved to the United States at age 16, she witnessed people doing detoxes or restricting certain food groups or ingredients. Surrounded by that narrative and an abundance of new foods in her college dining hall, she says she “gained the freshman 31 instead of the freshman 15.” When she returned home to Egypt that summer, “I eased back into eating the Mediterranean food that I grew up with. During the span of about two months, I shed all of that weight without thinking I was ever on a diet.”
To help invite joy back to the table for others — and to keep her family’s culinary heritage alive for her two daughters (now 14 and 22) — Atlanta-based Karadsheh launched The Mediterranean Dish food blog 10 years ago. Quickly, her table started getting filled with more than just her friends and family.

“I started receiving emails from folks whose doctors had prescribed the Mediterranean diet and were seeking approachable recipes,” Karadsheh said. The plant-based eating lifestyle, often rated the world’s best diet, can reduce the risk for diabetes, high cholesterol, dementia, memory loss and depression, according to research. What’s more, the meal plan has been linked to stronger bones, a healthier heart and longer life.

Preparing meals the Mediterranean way, according to Karadsheh, can help you “eat well and live joyfully. To us, ‘diet’ doesn’t mean a list of ‘eat this’ and ‘don’t eat that.’” Instead of omission, Karadsheh focuses on abundance, asking herself, “what can I add to my life through this way of living? More whole foods, vegetables, grains, legumes? Naturally, when you add these good-for-you ingredients, you eat less of what’s not as health-promoting,” she told CNN.

Automatic takeoffs are coming for passenger jets and they’re going to redraw the map of the sky
kra cc

In late 1965, at what’s now London Heathrow airport, a commercial flight coming from Paris made history by being the first to land automatically.

The plane – A Trident 1C operated by BEA, which would later become British Airways – was equipped with a newly developed extension of the autopilot (a system to help guide the plane’s path without manual control) known as “autoland.”

Today, automatic landing systems are installed on most commercial aircraft and improve the safety of landings in difficult weather or poor visibility.

Now, nearly 60 years later, the world’s third largest aircraft manufacturer, Brazil’s Embraer, is introducing a similar technology, but for takeoffs.

Called “E2 Enhanced Take Off System,” after the family of aircraft it’s designed for, the technology would not only improve safety by reducing pilot workload, but it would also improve range and takeoff weight, allowing the planes that use it to travel farther, according to Embraer.

“The system is better than the pilots,” says Patrice London, principal performance engineer at Embraer, who has worked on the project for over a decade. ”That’s because it performs in the same way all the time. If you do 1,000 takeoffs, you will get 1,000 of exactly the same takeoff.”

Embraer, London adds, has already started flight testing, with the aim to get it approved by aviation authorities in 2025, before introducing it from select airports.

Arrowheads reveal the presence of a mysterious army in Europe’s oldest battle
жесткое порно
Today, the lush, green valley surrounding the Tollense River in northeast Germany appears to be a serene place to appreciate nature.

But to archaeologists, the Tollense Valley is considered Europe’s oldest battlefield.

An amateur archaeologist first spotted a bone sticking out of the riverbank in 1996.

A series of ongoing site excavations since 2008 has shown that the thousands of bones and hundreds of weapons preserved by the valley’s undisturbed environment were part of a large-scale battle 3,250 years ago.

The biggest mysteries that researchers aim to uncover are why the battle occurred and who fought in it. These are questions that they are now one step closer to answering.
ozens of bronze and flint arrowheads recovered from the Tollense Valley are revealing details about the able-bodied warriors who fought in the Bronze Age battle.

The research team analyzed and compared the arrowheads, some of which were still embedded in the remains of the fallen. While many of these weapons were locally produced, some bearing different shapes came from a region that now includes modern Bavaria and Moravia.

The outliers’ presence suggests that a southern army clashed with local tribes in the valley, and researchers suspect the conflict began at a key landmark along the river.

Back to the future
Scientists are harnessing the power of artificial intelligence to detect hidden archaeological sites buried below the sand of the sprawling Rub‘ al-Khali desert.

The desert spans 250,000 square miles (650,000 square kilometers) on the Arabian Peninsula, and its name translates to “the Empty Quarter” in English. To unravel the secrets of the desolate terrain, researchers are combining machine learning with a satellite imagery technique that uses radio waves to spot objects that may be concealed beneath surfaces.

The technology will be tested in October when excavations assess whether predicted structures are present at the Saruq Al Hadid complex in Dubai, United Arab Emirates.

Separately, an AI-assisted analysis uncovered a trove of ancient symbols in Peru’s Nazca Desert, nearly doubling the number of known geoglyphs, or stone and gravel arranged into giant shapes that depict animals, humans and geometric designs.

Hong Kong plans to install thousands of surveillance cameras. Critics say it’s more proof the city is moving closer to China
бесплатная консультация по телефону юрист

Glance up while strolling through parts of downtown Hong Kong and, chances are, you’ll notice the glassy black lens of a surveillance camera trained on the city’s crowded streets.

And that sight will become more common in the coming years, as the city’s police pursue an ambitious campaign to install thousands of cameras to elevate their surveillance capabilities.

Though it consistently ranks among the world’s safest big cities, police in the Asian financial hub say the new cameras are needed to fight crime – and have raised the possibility of equipping them with powerful facial recognition and artificial intelligence tools.

That’s sparked alarm among some experts who see it as taking Hong Kong one step closer to the pervasive surveillance systems of mainland China, warning of the technology’s repressive potential.

Hong Kong police had previously set a target of installing 2,000 new surveillance cameras this year, and potentially more than that each subsequent year. The force plans to eventually introduce facial recognition to these cameras, security chief Chris Tang told local media in July – adding that police could use AI in the future to track down suspects.
In a statement to CNN, the Hong Kong Police Force said it was studying how police in other countries use surveillance cameras, including how they use AI. But it’s not clear how many of the new cameras may have facial recognition capabilities, or whether there’s a timeline for when the tech will be introduced.

Tang and the Hong Kong police have repeatedly pointed to other jurisdictions, including Western democracies, that also make wide use of surveillance cameras for law enforcement. For instance, Singapore has 90,000 cameras and the United Kingdom has more than seven million, Tang told local newspaper Sing Tao Daily in June.

While some of those places, like the UK, have started using facial recognition cameras, experts say these early experiments have highlighted the need for careful regulation and privacy protections. Hong Kong police told CNN they would “comply with relevant laws” and follow strong internal guidelines – but haven’t elaborated in depth on what that would look like.

Роман Василенко – Парадигма Успеха!
Роман Викторович Василенко
Психологи оценивают лидерство, как умение мотивировать, сплачивать, принимать быстрые решения. Но истинным лидерам присуще еще одно качество, о котором умалчивают специалисты. Лидер – это человек, способный сделать других счастливее. Неслучайно, что во время затянувшейся экономической нестабильности мы ищем образец для подражания – человека, который пройдя все перипетии жизненного пути, добился значительных высот, делится своими знаниями и накопленным опытом.

Для многих россиян таким человеком стал Роман Викторович Василенко –идейный вдохновитель, основатель холдинга Life Is Good и председатель правления ЖК Best Way.

Получив высшее экономическое образование в Ярославском Высшем Военном Финансовом Училище, он на рубеже XXI века принял решение совершенствоваться в профессии – продолжить обучение в области экономики и финансов на международных курсах. Полученные знания подкреплялись практическим опытом. За 15 лет работы в швейцарской корпорации Роман Викторович прошел путь от финансового консультанта до управляющего директора.
В настоящее время Роман Василенко – кандидат экономических наук, президент Международной бизнес-академии IBA, досконально владеет навыками сетевого маркетинга. Следует отметить, что данный принцип построения бизнеса не имеет ничего общего с финансовыми пирамидами. Сетевой маркетинг за 70-летнийопыт успешного развития, доказал свою жизнеспособность и экономическую целесообразность.

Роман Викторович имел великолепные возможности перебраться за границу и там применять свои знания и опыт. Но оставаясь патриотом своей страны, коренным петербуржцем он неоднократно делом доказывал свою любовь к Родине. Не сменил Россию на сладкую жизнь, когда компаньон по бизнесу после года упорной работы оставил Романа с семьей буквально ни с чем. Не погнался за длинным рублем, махнув на все рукой, когда в январе 2014 года его детище – молодая компания – переживало рейдерский захват.

Честь, совесть, независимая воля – это не просто слова для Романа Василенко. Как настоящий мужчина и офицер запаса он привык держать слово, отвечать за принятые обязательства. Люди доверили ему свои деньги, и он не мог их разочаровать. Воинская дисциплина и врожденные качества характера помогли Роману мобилизоваться, преодолеть сложные жизненные рубежи и уверенно двигаться к намеченной цели. Его твердые решения основаны на том, что лучше для всей корпорации; а не только для нескольких партнеров.

Но не одни только деловые качества являются основными признаками успеха Василенко. Людей больше привлекает его жизненное кредо. Те, кому посчастливилось работать с Романом Викторовичем, характеризуют его как филантропа и нравственного бизнесмена. Представители более близкого окружения рассказывают о его трепетном отношении к семье, друзья – о горячей любви к яхтам и дайвингу. И все в один голос заявляют о его безукоризненной честности. Сам Роман Викторович говорит, что этим он обязан своим родителям и в первую очередь матери, о которой он всегда говорит с особой теплотой и нежностью.

На протяжении многих лет Роман мечтал не просто о собственном бизнесе, а принципиально новом подходе к делу. Идея, казалось, витала в воздухе, для ее формирования не хватало одного толчка. Таким толчком стала главная тема саммита стран ШОС, участником которого был Василенко, «Как сохранить человеческий капитал и предотвратить утечку мозгов из России». Как известно, главная трудность молодых перспективных кадров – это отсутствие жилья и сложность его приобретения. По мнению Романа Викторовича необходимо дать возможность людям заработать на приобретение жилья, чтобы устранить главную причину миграции кадров. Ярославском Высшем Военном Финансовом Училище, он на рубеже XXI века принял решение совершенствоваться в профессии – продолжить обучение в области экономики и финансов на международных курсах. Полученные знания подкреплялись практическим опытом. За 15 лет работы в швейцарской корпорации Роман Викторович прошел путь от финансового консультанта до управляющего директора.
