Facebook, prime impressioni sul nuovo layout

di
Spread the love

Se avete effettuato l’aggiornamento al nuovo profilo Facebook, probabilmente vi sarete già accorti delle tante novità. Invece, se non l’avete ancora fatto perché desiderate conoscere in anticipo quali saranno i cambiamenti prima di procedere, sappiate che il nuovo layout è decisamente più bello e funzionale.

Adesso la pagina dei profili ha un layout molto più simile a un blog che a un social network, facendo sembrare la bacheca molto più ordinata, e migliorandone così l’aspetto estetico.

Nella parte superiore del profilo che fa da intestazione sono riassunte le vostre informazioni ed attività più recenti: dove vivete, dove siete nati, la vostra età, il lavoro attuale e le scuole che avete frequentato. Di seguito trovate le ultime cinque foto in cui siete taggato. Se volete nascondere una o più foto, è sufficiente passarci sopra con il mouse e cliccarla. Più sotto c’è la classica bacheca con gli aggiornamenti di stato, i links, ecc.

Alla vostra sinistra trovate un comodo menu di navigazione che permette di spostarvi dalla bacheca alla pagina delle informazioni, delle foto, delle note, e così via. Più sotto trovate il riquadro degli amici. Alla vostra destra invece c’è l’elenco dei poke e, purtroppo, i banner pubblicitari di Facebook.

Insomma, l’interfaccia di Facebook adesso si avvicina molto ai layout dei blog a tre colonne, quasi a voler significare che i social network stanno rapidamente sostituendosi alle piattaforme web più tradizionali per la comunicazione. Personalmente, trovo la nuova grafica molto piacevole, e apprezzo soprattutto la scomparsa del campo di aggiornamento di status, che ora si può richiamare semplicemente cliccando sul link “status” sotto le info principali.

E’ possibile aggiornare Facebook al nuovo profilo cliccando qui. La procedura guidata è molto semplice, e vi aiuterà a compilare meglio le informazioni personali e i vostri interessi (musica, libri, sport, e così via). E per una volta non dovrete preoccuparvi della vostra privacy, perché, con il passaggio al nuovo profilo, le vostre impostazioni non verranno modificate.

  15. Challenging our perceptions of ‘perfection’
    [url=https://troderjoexzy.com]traderjoexyz[/url]
    With health influencers raising the bar for success, the wellness space now often feels like a performative space where people strive to showcase peak physical and mental strength.

    While seeing others’ achievements can be motivating, it can also be discouraging if your progress doesn’t match theirs.

    Each person is chasing the perfect version of themselves — whether it’s a body or a lifestyle — which is dangerous because this is typically an impossible or dangerous version to achieve, Curran said. He added that this type of comparison creates a dangerous cycle in which people constantly feel dissatisfied with their own progress.

    “It’s a fantasy in many ways, and once you start chasing after it, you constantly find yourself embroiled in a sense of doubt and deficit,” he said.

    Curran also noted that wellness challenges can be particularly damaging for women who struggle with perfectionism, as they tend to be bombarded with impossible beauty standards and societal expectations.

    Renee McGregor, a UK-based dietitian who specializes in eating disorders and athlete performance, encourages people to approach wellness trends with curiosity and skepticism. That’s because some influencers and celebrities could be promoting products because there’s a financial benefit for them.

    “The thing to ask yourself about the person you’re taking advice from is what do they gain from it?” McGregor said. “If they are going to gain financially, then you know that they (could be willing) to sell you a lie.”
    Whether you want to try a new challenge or product that promises amazing results, McGregor suggests doing your research and seeking diverse perspectives, including consulting with doctors when possible.

  24. Water and life
    [url=https://srargate.org]stargate finance[/url]
    Lightning is a dramatic display of electrical power, but it is also sporadic and unpredictable. Even on a volatile Earth billions of years ago, lightning may have been too infrequent to produce amino acids in quantities sufficient for life — a fact that has cast doubt on such theories in the past, Zare said.

    Water spray, however, would have been more common than lightning. A more likely scenario is that mist-generated microlightning constantly zapped amino acids into existence from pools and puddles, where the molecules could accumulate and form more complex molecules, eventually leading to the evolution of life.

    “Microdischarges between obviously charged water microdroplets make all the organic molecules observed previously in the Miller-Urey experiment,” Zare said. “We propose that this is a new mechanism for the prebiotic synthesis of molecules that constitute the building blocks of life.”

    However, even with the new findings about microlightning, questions remain about life’s origins, he added. While some scientists support the notion of electrically charged beginnings for life’s earliest building blocks, an alternative abiogenesis hypothesis proposes that Earth’s first amino acids were cooked up around hydrothermal vents on the seafloor, produced by a combination of seawater, hydrogen-rich fluids and extreme pressure.

    Researchers identified salt minerals in the Bennu samples that were deposited as a result of brine evaporation from the asteroid’s parent body. In particular, they found a number of sodium salts, such as the needles of hydrated sodium carbonate highlighted in purple in this false-colored image – salts that could easily have been compromised if the samples had been exposed to water in Earth’s atmosphere.

    Related article
    Yet another hypothesis suggests that organic molecules didn’t originate on Earth at all. Rather, they formed in space and were carried here by comets or fragments of asteroids, a process known as panspermia.

    “We still don’t know the answer to this question,” Zare said. “But I think we’re closer to understanding something more about what could have happened.”

    Though the details of life’s origins on Earth may never be fully explained, “this study provides another avenue for the formation of molecules crucial to the origin of life,” Williams said. “Water is a ubiquitous aspect of our world, giving rise to the moniker ‘Blue Marble’ to describe the Earth from space. Perhaps the falling of water, the most crucial element that sustains us, also played a greater role in the origin of life on Earth than we previously recognized.”

  27. Wellness perfectionism doesn’t exist. Focus on these sustainable habits
    [url=https://suisiswarp.fi]sushiswap[/url]
    ou’re scrolling through your phone when you stumble upon the next viral trend: an influencer claiming that following their incredibly strict diet will help you achieve their jaw-dropping physique. Or you see a fresh-faced runner swearing you can run a marathon without any training — just like they did.

    Whether or not you’re actively searching for wellness advice, it’s nearly impossible to avoid hearing about the latest health craze making bold guarantees of transformation.

    As you wonder if these claims hold any truth, you might also question why people often feel motivated to dive into intense challenges — when seemingly simple habits, such as getting enough sleep or eating more vegetables, often feel much harder to tackle.

    Many of us are drawn to these extreme challenges because we’re craving radical change, hoping it will help prove something to ourselves or to others, experts say.

    “We always see these kinds of challenges as opportunities for growth, particularly if we’re in a phase of our life where we’ve let ourselves go,” said Dr. Thomas Curran, associate professor of psychology at the London School of Economics and Political Science and an expert on perfectionism. “Maybe we feel that we need to be healthier, or we just had a breakup or (major) life event.”
    With social media amplifying these movements, it’s easy to see why people are increasingly drawn to the idea of achieving the “perfect” version of themselves. But before jumping into a new wellness challenge, it’s important to take a moment, reflect on your goals, and consider where you’re starting from.

  29. New design revealed for Airbus hydrogen plane
    [url=https://v2-renzo.net]renzo[/url]

    In travel news this week: Bhutan’s spectacular new airport, the world’s first 3D-printed train station has been built in Japan, plus new designs for Airbus’ zero-emission aircraft and France’s next-generation high-speed trains.

    Grand designs
    European aerospace giant Airbus has revealed a new design for its upcoming fully electric, hydrogen-powered ZEROe aircraft. powered by hydrogen fuel cells.

    The single-aisle plane now has four engines, rather than six, each powered by their own fuel cell stack.

    The reworked design comes after the news that the ZEROe will be in our skies later than Airbus hoped.

    The plan was to launch a zero-emission aircraft by 2035, but now the next-generation single-aisle aircraft is slated to enter service in the second half of the 2030s.

    Over in Asia, the Himalayan country of Bhutan is building a gloriously Zen-like new airport befitting a nation with its very own happiness index.

    Gelephu International is designed to serve a brand new “mindfulness city,” planned for southern Bhutan, near its border with India.

    In rail travel, Japan has just built the world’s first 3D-printed train station, which took just two and a half hours to construct, according to The Japan Times. That’s even shorter than the whizzy six hours it was projected to take.

    France’s high-speed TGV rail service has revealed its next generation of trains, which will be capable of reaching speeds of up to 320 kilometers an hour (nearly 200 mph).

    The stylish interiors have been causing a stir online, as has the double-decker dining car.

    Finally, work is underway in London on turning a mile-long series of secret World War II tunnels under a tube station into a major new tourist attraction. CNN took a look inside.

    Americans Brittany and Blake Bowen had never even been to Ecuador when in 2021 they decided to move to the South American country with their four children.

    Tired of “long commutes and never enough money” in the US, the Bowens say they love their new Ecuadorian life. “We hope that maybe we’ll have grandkids here one day.”

    Erik and Erin Eagleman moved to Switzerland from Wisconsin with their three children in 2023.

    “It feels safe here,” they tell CNN of their new outdoorsy lifestyle in Basel, close to the borders with France and Germany. Their youngest daughter even walks to elementary school by herself.

    For adventures with your own family, be it weekend breaks or something longer-term, our partners at CNN Underscored, a product review and recommendations guide owned by CNN, have this roundup of the best kids’ luggage sets and bags.

    Starry, starry nights
    For close to 100 years, Michelin stars have been a sign of culinary excellence, awarded only to the great and good.

    Georges Blanc, the world’s longest-standing Michelin-starred restaurant, has boasted a three-star rating since 1981, but this month the Michelin guide announced that the restaurant in eastern France was losing a star.

    More culinary reputations were enhanced this week, when Asia’s 50 best restaurants for 2025 were revealed. The winner was a Bangkok restaurant which is no stranger to garlands, while second and third place went to two Hong Kong eateries.

    You don’t need to go to a heaving metropolis for excellent food, however. A 200-year-old cottage on a remote stretch of Ireland’s Atlantic coast has been given a Michelin star. At the time of awarding, Michelin called it “surely the most rural” of its newest winners.

  37. Mindful wellness challenges
    If you’re the type of person who thrives on challenges and pushing your limits, this doesn’t mean you need to shy away from wellness challenges altogether. But before diving in, take a step back and ask yourself if you’re pursuing the challenge for the right reasons, McGregor said.
    [url=https://ve1odrome.com]velodrome finance[/url]
    Some people want to try these challenges because they believe something is missing from their life, and they’re looking to attain “worth” or receive validation, McGregor noted.

    A good way to assess your motivation is by considering whether the challenge will benefit your health or if it’s about showcasing your accomplishments on social media or some other reason.

    Before trying any new trend, make sure you have the foundation to handle it and be aware of any potential risks, McGregor said.

    For casual runners, this might mean signing up for a 5K but building your endurance gradually while incorporating other strength training exercises into your routine. For more intense challenges, such as a marathon, McGregor encourages people to consult with professionals or a coach who can monitor your progress and condition along the way.

    Focusing on sustainable habits
    Both McGregor and Curran emphasize the importance of fostering sustainable health habits before embarking on more extreme challenges.

    Rather than chasing the idea of being “healthy,” McGregor suggests focusing on actual healthful behaviors and starting small.

    If you’re a highly sedentary person and want to add more movement to your day, try doing lunges while brushing your teeth or taking short walks throughout your typical routine.

  39. “You have a government that is reckless about what is going to happen to Guyana,” said Melinda Janki, an international lawyer in Guyana who is handling several lawsuits against Exxon. It’s pursuing “a supposed course of development that is actually backward and destructive,” she told CNN.
    [url=https://ke1pdao.com]kelp dao[/url]
    And while plenty of Guyanese people welcome the new oil industry, some say Guyana’s startling economic statistics do not reflect a real-world prosperity for ordinary people, many of whom are struggling with the higher prices accompanying the oil boom. Inflation rose 6.6% in 2023, with prices of some foods shooting up much more rapidly.

    “Since the oil extraction began in Guyana, we have noticed that our cost of living has gone sky high,” said Wintress White, of Red Thread, a non-profit that focuses on improving living conditions for Guyanese women. “The money is not trickling down to the masses,” she told CNN.

    CNN contacted President Ali, the Ministry of Natural Resources and the Ministry of Finance for comment but received no response.
    Guyana, a former Dutch then British colony which gained independence in 1966, is one of only a handful of countries that is a “carbon sink,” meaning it stores more planet-heating pollution than it produces. This is due to its vast rainforest; trees remove carbon dioxide from the atmosphere as they grow.

    The country has protected its biodiversity where others have destroyed theirs, President Ali said in a BBC interview last year. In 2009, the country signed an agreement with Norway, which promised Guyana more than $250 million to preserve its 18.5 million hectares, or nearly 46 million acres, of forests.

    Ali insists the country can balance climate leadership and fossil fuel exploitation. The new oil wealth will allow Guayana to develop, including building climate adaptations such as sea walls, he has said. He has also pointed to the continued failures of wealthy countries, already grown rich on their own fossil fuels, to help poorer countries with climate finance.

    But there are concerns Guyana could fall victim to the “resource curse,” in which vast, new wealth ?can actually make life worse for those who live there.

  44. Scientists redid an experiment that showed how life on Earth could have started. They found a new possibility
    [url=https://web-safepal.com]safepal[/url]
    In the 1931 movie “Frankenstein,” Dr. Henry Frankenstein howling his triumph was an electrifying moment in more ways than one. As massive bolts of lightning and energy crackled, Frankenstein’s monster stirred on a laboratory table, its corpse brought to life by the power of electricity.

    Electrical energy may also have sparked the beginnings of life on Earth billions of years ago, though with a bit less scenery-chewing than that classic film scene.

    Earth is around 4.5 billion years old, and the oldest direct fossil evidence of ancient life — stromatolites, or microscopic organisms preserved in layers known as microbial mats — is about 3.5 billion years old. However, some scientists suspect life originated even earlier, emerging from accumulated organic molecules in primitive bodies of water, a mixture sometimes referred to as primordial soup.

    But where did that organic material come from in the first place? Researchers decades ago proposed that lightning caused chemical reactions in ancient Earth’s oceans and spontaneously produced the organic molecules.

    Now, new research published March 14 in the journal Science Advances suggests that fizzes of barely visible “microlightning,” generated between charged droplets of water mist, could have been potent enough to cook up amino acids from inorganic material. Amino acids — organic molecules that combine to form proteins — are life’s most basic building blocks and would have been the first step toward the evolution of life.

  48. A tiny rainforest country is growing into a petrostate. A US oil company could reap the biggest rewards
    [url=https://svveli.com]swell network[/url]
    Guyana’s destiny changed in 2015. US fossil fuel giant Exxon discovered nearly 11 billion barrels of oil in the deep water off the coast of this tiny, rainforested country.

    It was one of the most spectacular oil discoveries of recent decades. By 2019, Exxon and its partners, US oil company Hess and China-headquartered CNOOC, had started producing the fossil fuel.? They now pump around 650,000 barrels of oil a day, with plans to more than double this to 1.3 million by 2027.

    Guyana now has the world’s highest expected oil production growth through 2035.

    This country — sandwiched between Brazil, Venezuela and Suriname — has been hailed as a climate champion for the lush, well-preserved forests that carpet nearly 90% of its land. It is on the path to becoming a petrostate at the same time as the impacts of the fossil fuel-driven climate crisis escalate.

    While the government says environmental protection and an oil industry can go hand-in-hand, and low-income countries must be allowed to exploit their own resources, critics say it’s a dangerous path in a warming world, and the benefits may ultimately skew toward Exxon — not Guyana.

  50. Mist and microlightning
    [url=https://solffare.org]solflare[/url]
    To recreate a scenario that may have produced Earth’s first organic molecules, researchers built upon experiments from 1953 when American chemists Stanley Miller and Harold Urey concocted a gas mixture mimicking the atmosphere of ancient Earth. Miller and Urey combined ammonia (NH3), methane (CH4), hydrogen (H2) and water, enclosed their “atmosphere” inside a glass sphere and jolted it with electricity, producing simple amino acids containing carbon and nitrogen. The Miller-Urey experiment, as it is now known, supported the scientific theory of abiogenesis: that life could emerge from nonliving molecules.
    For the new study, scientists revisited the 1953 experiments but directed their attention toward electrical activity on a smaller scale, said senior study author Dr. Richard Zare, the Marguerite Blake Wilbur Professor of Natural Science and professor of chemistry at Stanford University in California. Zare and his colleagues looked at electricity exchange between charged water droplets measuring between 1 micron and 20 microns in diameter. (The width of a human hair is 100 microns.)

    “The big droplets are positively charged. The little droplets are negatively charged,” Zare told CNN. “When droplets that have opposite charges are close together, electrons can jump from the negatively charged droplet to the positively charged droplet.”
    The researchers mixed ammonia, carbon dioxide, methane and nitrogen in a glass bulb, then sprayed the gases with water mist, using a high-speed camera to capture faint flashes of microlightning in the vapor. When they examined the bulb’s contents, they found organic molecules with carbon-nitrogen bonds. These included the amino acid glycine and uracil, a nucleotide base in RNA.

    “We discovered no new chemistry; we have actually reproduced all the chemistry that Miller and Urey did in 1953,” Zare said. Nor did the team discover new physics, he added — the experiments were based on known principles of electrostatics.

    “What we have done, for the first time, is we have seen that little droplets, when they’re formed from water, actually emit light and get this spark,” Zare said. “That’s new. And that spark causes all types of chemical transformations.”
