NASA’s CloudSat Ends Mission Peering Into the Heart of Clouds
Tue, 23 Apr 2024 17:23:53 +0000
Over the course of nearly two decades, its powerful radar provided never-before-seen details of clouds and helped advance global weather and climate predictions. CloudSat, a NASA mission that peered into hurricanes, tallied global snowfall rates, and achieved other weather and climate firsts, has ended its operations. Originally proposed as a 22-month mission, the spacecraft was […]

Claire O’Neill, a former climate minister, says PM’s move was to ‘try and create political division and dividing lines’
The UK government’s decision to weaken some of its climate commitments was a “retrograde step” that would set back vital cross-party action to cut carbon emissions, Claire O’Neill, a former Conservative climate minister, has said.
O’Neill, who was known as Claire Perry when she served as a minister under David Cameron and Theresa May, said the rolling back of emission reduction efforts by Rishi Sunak appeared to be a ploy for political advantage.

Julian Medina comes from a long line of fishers in the north of Colombia’s Gulf of Morrosquillo who use small-scale and often traditional methods to catch species such as mackerel, tuna and cojinúa.
Medina went into business as a young man but was drawn back to his roots, and ended up leading a fishing organisation. For years he has campaigned against the encroachment of fossil fuel companies, pollution and overfishing, which are destroying the gulf’s delicate ecosystem and people’s livelihoods.

SEMrush and Ahrefs are among
the most popular tools in the SEO industry. Both companies have been in
business for years and have thousands of customers per month.
If you're a professional SEO or trying to do digital
marketing on your own, at some point you'll likely consider using a tool to
help with your efforts. Ahrefs and SEMrush are two names that will likely
appear on your shortlist.
In this guide, I'm going to help you learn more about these SEO tools and how to choose the one that's best for your purposes.
What is SEMrush?
SEMrush is a popular SEO tool with a wide range of
features—it's the leading competitor research service for online marketers.
SEMrush's SEO Keyword Magic tool offers over 20 billion Google-approved
keywords, which are constantly updated and it's the largest keyword database.
The program was developed in 2007 as SeoQuake is a
small Firefox extension
Features
Ahrefs is a leading SEO platform that offers a set of
tools to grow your search traffic, research your competitors, and monitor your
niche. The company was founded in 2010, and it has become a popular choice
among SEO tools. Ahrefs has a keyword index of over 10.3 billion keywords and
offers accurate and extensive backlink data updated every 15-30 minutes and it
is the world's most extensive backlink index database.
Features
Direct Comparisons: Ahrefs vs SEMrush
Now that you know a little more about each tool, let's
take a look at how they compare. I'll analyze each tool to see how they differ
in interfaces, keyword research resources, rank tracking, and competitor
analysis.
User Interface
Ahrefs and SEMrush both offer comprehensive information
and quick metrics regarding your website's SEO performance. However, Ahrefs
takes a bit more of a hands-on approach to getting your account fully set up,
whereas SEMrush's simpler dashboard can give you access to the data you need
quickly.
In this section, we provide a brief overview of the elements
found on each dashboard and highlight the ease with which you can complete
tasks.
AHREFS
The Ahrefs dashboard is less cluttered than that of
SEMrush, and its primary menu is at the very top of the page, with a search bar
designed only for entering URLs.
Additional features of the Ahrefs platform include:
SEMRUSH
When you log into the SEMrush Tool, you will find four
main modules. These include information about your domains, organic keyword
analysis, ad keyword, and site traffic.
You'll also find some other options like
Both Ahrefs and SEMrush have user-friendly dashboards,
but Ahrefs is less cluttered and easier to navigate. On the other hand, SEMrush
offers dozens of extra tools, including access to customer support resources.
When deciding on which dashboard to use, consider what
you value in the user interface, and test out both.
If you're looking to track your website's search engine
ranking, rank tracking features can help. You can also use them to monitor your
competitors.
Let's take a look at Ahrefs vs. SEMrush to see which
tool does a better job.
The Ahrefs Rank Tracker is simpler to use. Just type in
the domain name and keywords you want to analyze, and it spits out a report
showing you the search engine results page (SERP) ranking for each keyword you
enter.
Rank Tracker looks at the ranking performance of
keywords and compares them with the top rankings for those keywords. Ahrefs
also offers:
You'll see metrics that help you understand your
visibility, traffic, average position, and keyword difficulty.
It gives you an idea of whether a keyword would be
profitable to target or not.
SEMRush offers a tool called Position Tracking. This
tool is a project tool—you must set it up as a new project. Below are a few of
the most popular features of the SEMrush Position Tracking tool:
All subscribers are given regular data updates and
mobile search rankings upon subscribing
The platform provides opportunities to track several
SERP features, including Local tracking.
Intuitive reports allow you to track statistics for the
pages on your website, as well as the keywords used in those pages.
Identify pages that may be competing with each other
using the Cannibalization report.
Ahrefs is a more user-friendly option. It takes seconds
to enter a domain name and keywords. From there, you can quickly decide whether
to proceed with that keyword or figure out how to rank better for other
keywords.
SEMrush allows you to check your mobile rankings and
ranking updates daily, which is something Ahrefs does not offer. SEMrush also
offers social media rankings, a tool you won't find within the Ahrefs platform.
Both are good which one do you like let me know in the comment.
Keyword research is closely related to rank tracking,
but it's used for deciding which keywords you plan on using for future content
rather than those you use now.
When it comes to SEO, keyword research is the most
important thing to consider when comparing the two platforms.
The Ahrefs Keyword Explorer provides you with thousands
of keyword ideas and filters search results based on the chosen search engine.
Ahrefs supports several features, including:
SEMrush's Keyword Magic Tool has over 20 billion
keywords for Google. You can type in any keyword you want, and a list of
suggested keywords will appear.
The Keyword Magic Tool also lets you to:
Both of these tools offer keyword research features and
allow users to break down complicated tasks into something that can be
understood by beginners and advanced users alike.
If you're interested in keyword suggestions, SEMrush
appears to have more keyword suggestions than Ahrefs does. It also continues to
add new features, like the Keyword Gap tool and SERP Questions recommendations.
Both platforms offer competitor analysis tools,
eliminating the need to come up with keywords off the top of your head. Each
tool is useful for finding keywords that will be useful for your competition so
you know they will be valuable to you.
Ahrefs' domain comparison tool lets you compare up to five websites (your website and four competitors) side-by-side.it also shows you how your site is ranked against others with metrics such as backlinks, domain ratings, and more.
Use the Competing Domains section to see a list of your
most direct competitors, and explore how many keywords matches your competitors
have.
To find more information about your competitor, you can
look at the Site Explorer and Content Explorer tools and type in their URL
instead of yours.
SEMrush provides a variety of insights into your
competitors' marketing tactics. The platform enables you to research your
competitors effectively. It also offers several resources for competitor
analysis including:
Traffic Analytics helps you identify where your
audience comes from, how they engage with your site, what devices visitors use
to view your site, and how your audiences overlap with other websites.
SEMrush's Organic Research examines your website's
major competitors and shows their organic search rankings, keywords they are
ranking for, and even if they are ranking for any (SERP) features and more.
The Market Explorer search field allows you to type in
a domain and lists websites or articles similar to what you entered. Market
Explorer also allows users to perform in-depth data analytics on These
companies and markets.
SEMrush wins here because it has more tools dedicated to
competitor analysis than Ahrefs. However, Ahrefs offers a lot of functionality
in this area, too. It takes a combination of both tools to gain an advantage
over your competition.
When it comes to keyword data research, you will become
confused about which one to choose.
Consider choosing Ahrefs if you
Consider SEMrush if you:
Both tools are great. Choose the one which meets your
requirements and if you have any experience using either Ahrefs or SEMrush let
me know in the comment section which works well for you.

Glen Powell and Zoey Deutch ooze chemistry in this under-appreciated romcom about two overworked assistants trying to set up their bosses
Working long into the night for their Machiavellian bosses, a serendipitous meet-cute brings two beleaguered assistants together. There is Harper (Zoey Deutch), who dreams of making it as a writer like her boss, gun sports editor Kirsten Stevens (Lucy Liu, accurately described as having “a fierceness that’s both scary and inspiring”).
And there is Charlie (Glen Powell), who is desperate for a promotion, hoping to impress not only his boss, unscrupulous VC power player Rick Otis (Taye Diggs, revelling in his role as an arrogant jerk) but also his materialistic model girlfriend Suze (actual Victoria’s Secret model Joan Smalls).

Non-fungible tokens (NFTs) are the most popular digital assets today, capturing the attention of cryptocurrency investors, whales and people from around the world. People find it amazing that some users spend thousands or millions of dollars on a single NFT-based image of a monkey or other token, but you can simply take a screenshot for free. So here we share some freuently asked question about NFTs.
NFT stands for non-fungible token, which is a cryptographic token on a blockchain with unique identification codes that distinguish it from other tokens. NFTs are unique and not interchangeable, which means no two NFTs are the same. NFTs can be a unique artwork, GIF, Images, videos, Audio album. in-game items, collectibles etc.
A blockchain is a distributed digital ledger that allows for the secure storage of data. By recording any kind of information—such as bank account transactions, the ownership of Non-Fungible Tokens (NFTs), or Decentralized Finance (DeFi) smart contracts—in one place, and distributing it to many different computers, blockchains ensure that data can’t be manipulated without everyone in the system being aware.
The value of an NFT comes from its ability to be traded freely and securely on the blockchain, which is not possible with other current digital ownership solutionsThe NFT points to its location on the blockchain, but doesn’t necessarily contain the digital property. For example, if you replace one bitcoin with another, you will still have the same thing. If you buy a non-fungible item, such as a movie ticket, it is impossible to replace it with any other movie ticket because each ticket is unique to a specific time and place.
One of the unique characteristics of non-fungible tokens (NFTs) is that they can be tokenised to create a digital certificate of ownership that can be bought, sold and traded on the blockchain.
As with crypto-currency, records of who owns what are stored on a ledger that is maintained by thousands of computers around the world. These records can’t be forged because the whole system operates on an open-source network.
NFTs also contain smart contracts—small computer programs that run on the blockchain—that give the artist, for example, a cut of any future sale of the token.
Non-fungible tokens (NFTs) aren't cryptocurrencies, but they do use blockchain technology. Many NFTs are based on Ethereum, where the blockchain serves as a ledger for all the transactions related to said NFT and the properties it represents.5) How to make an NFT?
Anyone can create an NFT. All you need is a digital wallet, some ethereum tokens and a connection to an NFT marketplace where you’ll be able to upload and sell your creations
When you purchase a stock in NFT, that purchase is recorded on the blockchain—the bitcoin ledger of transactions—and that entry acts as your proof of ownership.
The value of an NFT varies a lot based on the digital asset up for grabs. People use NFTs to trade and sell digital art, so when creating an NFT, you should consider the popularity of your digital artwork along with historical statistics.
In the year 2021, a digital artist called Pak created an artwork called The Merge. It was sold on the Nifty Gateway NFT market for $91.8 million.
Non-fungible tokens can be used in investment opportunities. One can purchase an NFT and resell it at a profit. Certain NFT marketplaces let sellers of NFTs keep a percentage of the profits from sales of the assets they create.
Many people want to buy NFTs because it lets them support the arts and own something cool from their favorite musicians, brands, and celebrities. NFTs also give artists an opportunity to program in continual royalties if someone buys their work. Galleries see this as a way to reach new buyers interested in art.
There are many places to buy digital assets, like opensea and their policies vary. On top shot, for instance, you sign up for a waitlist that can be thousands of people long. When a digital asset goes on sale, you are occasionally chosen to purchase it.
To mint an NFT token, you must pay some amount of gas fee to process the transaction on the Etherum blockchain, but you can mint your NFT on a different blockchain called Polygon to avoid paying gas fees. This option is available on OpenSea and this simply denotes that your NFT will only be able to trade using Polygon's blockchain and not Etherum's blockchain. Mintable allows you to mint NFTs for free without paying any gas fees.
The answer is no. Non-Fungible Tokens are minted on the blockchain using cryptocurrencies such as Etherum, Solana, Polygon, and so on. Once a Non-Fungible Token is minted, the transaction is recorded on the blockchain and the contract or license is awarded to whoever has that Non-Fungible Token in their wallet.
You can sell your work and creations by attaching a license to it on the blockchain, where its ownership can be transferred. This lets you get exposure without losing full ownership of your work. Some of the most successful projects include Cryptopunks, Bored Ape Yatch Club NFTs, SandBox, World of Women and so on. These NFT projects have gained popularity globally and are owned by celebrities and other successful entrepreneurs. Owning one of these NFTs gives you an automatic ticket to exclusive business meetings and life-changing connections.
That’s a wrap. Hope you guys found this article enlightening. I just answer some question with my limited knowledge about NFTs. If you have any questions or suggestions, feel free to drop them in the comment section below. Also I have a question for you, Is bitcoin an NFTs? let me know in The comment section below
What are the best meat- and dairy-free tortilla fillers?
Wanted: vegan fillings for quesadillas
“Quesadillas are my comfort food,” says Karla Zazueta, author of Norteña: Authentic Family Recipes from Northern Mexico. “They’re quick to make, and you can stuff them with just about anything and they’ll taste really good.” Spinach Mexican-style is just one such example, and ideal for a vegan spring lunch or quick dinner. “We call any vegetable cooked with tomato, onion and green chilli or coriander ‘Mexican-style’, because they’re the colours of the flag,” Zazueta says. And it’s “mega-easy”, too: heat a little vegetable oil, add tomatoes, onion and jalapeños – “if you don’t have any of those, use a bit of green pepper or coriander instead” – and fry for a few minutes. “Add the spinach and, once it’s wilted, season with salt. That’s it.”
Self-confessed quesadilla “super fan” Adriana Cavita, chef-owner of Cavita in cental London, sandwiches mushrooms sauteed with onions, garlic, chilli (fresh or dried, and herbs between her tortillas. “In Mexico, we use epazote [an indigenous herb with oregano and anise notes], but it’s hard to find in the UK, so here I’d use coriander or parsley instead,” she advises. Alternatively, make the most of courgettes: “Cut them into cubes, then saute with onion, garlic, chilli (again, fresh or dried), tomato puree and any fresh herbs you fancy [parsley or coriander, say],” adds Cavita, who might also include spices, such as coriander or cumin seeds. Similarly, if Zazueta is “feeling fancy”, she often looks to courgette flowers: “In Mexico in spring, that’s the most common quesadilla filling, but they do tend to be quite expensive in the UK.” Traditionally, those flowers would be combined with epazote, although in its absence Zazueta would be inclined to try basil or mint, as well as some green jalapeños to add a touch of bitterness: “It’s not quite the same, though.” Corn tortillas, however, are absolutely non-negotiable, because “they just taste nicer”.

When I first visited muscadet country in the early 2000s, things were looking bleak for producers of the once all-conquering local seafood-friendly dry white. Years of unchecked overproduction and a rather cavalier approach to quality in these Atlantic-buffeted vineyards around the mouth of the Loire estuary – not to mention the emergence of a wave of exuberantly fruity new rivals from the new world – had seen sales dwindle alarmingly. Few of the producers I saw were able to puncture the general air of pessimism and doom.
The shining exception on that trip was Guy Bossard, the owner of a small biodynamically farmed domaine called Domaine de l’Écu. Bossard, at the time an energetic 50-year-old, was a bubbling stream of ideas, but his thrilling dry white wines were every bit as eloquent. As resonant, precise and varied as the best white burgundy, and at a fraction of the price, they were a challenge to all my preconceived ideas about muscadet.

Drinking coffee takes time in Ethiopia, a nation of caffeine lovers. In her village in Kafa, Ethiopia’s coffee heartland, Hagre Bekele starts by roasting the raw green beans over an open fire. Then she grinds them by hand and brews them in a jebena, a bulbous, long-necked clay pot. The drink is ready when the coffee boils and almost overflows.
Her son, Abraham, serves the drink in small cups, filled to the brim, alongside thick chunks of bread and handfuls of roasted grains, a snack called kolo. When the first cup is drunk, Hagre brews the grounds twice more. Generally, it is considered rude not to offer three cups. She also burns incense: its aroma enhances the coffee’s taste, and some believe it keeps bad spirits away.

Imagine a world in which you can do transactions and many other things without having to give your personal information. A world in which you don’t need to rely on banks or governments anymore. Sounds amazing, right? That’s exactly what blockchain technology allows us to do.
It’s like your computer’s hard drive. blockchain is a technology that lets you store data in digital blocks, which are connected together like links in a chain.
Blockchain technology was originally invented in 1991 by two mathematicians, Stuart Haber and W. Scot Stornetta. They first proposed the system to ensure that timestamps could not be tampered with.
A few years later, in 1998, software developer Nick Szabo proposed using a similar kind of technology to secure a digital payments system he called “Bit Gold.” However, this innovation was not adopted until Satoshi Nakamoto claimed to have invented the first Blockchain and Bitcoin.
A blockchain is a distributed database shared between the nodes of a computer network. It saves information in digital format. Many people first heard of blockchain technology when they started to look up information about bitcoin.
Blockchain is used in cryptocurrency systems to ensure secure, decentralized records of transactions.
Blockchain allowed people to guarantee the fidelity and security of a record of data without the need for a third party to ensure accuracy.
To understand how a blockchain works, Consider these basic steps:
Let’s get to know more about the blockchain.
Blockchain records digital information and distributes it across the network without changing it. The information is distributed among many users and stored in an immutable, permanent ledger that can't be changed or destroyed. That's why blockchain is also called "Distributed Ledger Technology" or DLT.
Here’s how it works:
And that’s the beauty of it! The process may seem complicated, but it’s done in minutes with modern technology. And because technology is advancing rapidly, I expect things to move even more quickly than ever.
Even though blockchain is integral to cryptocurrency, it has other applications. For example, blockchain can be used for storing reliable data about transactions. Many people confuse blockchain with cryptocurrencies like bitcoin and ethereum.
Blockchain already being adopted by some big-name companies, such as Walmart, AIG, Siemens, Pfizer, and Unilever. For example, IBM's Food Trust uses blockchain to track food's journey before reaching its final destination.
Although some of you may consider this practice excessive, food suppliers and manufacturers adhere to the policy of tracing their products because bacteria such as E. coli and Salmonella have been found in packaged foods. In addition, there have been isolated cases where dangerous allergens such as peanuts have accidentally been introduced into certain products.
Tracing and identifying the sources of an outbreak is a challenging task that can take months or years. Thanks to the Blockchain, however, companies now know exactly where their food has been—so they can trace its location and prevent future outbreaks.
Blockchain technology allows systems to react much faster in the event of a hazard. It also has many other uses in the modern world.
Blockchain technology is safe, even if it’s public. People can access the technology using an internet connection.
Have you ever been in a situation where you had all your data stored at one place and that one secure place got compromised? Wouldn't it be great if there was a way to prevent your data from leaking out even when the security of your storage systems is compromised?
Blockchain technology provides a way of avoiding this situation by using multiple computers at different locations to store information about transactions. If one computer experiences problems with a transaction, it will not affect the other nodes.
Instead, other nodes will use the correct information to cross-reference your incorrect node. This is called “Decentralization,” meaning all the information is stored in multiple places.
Blockchain guarantees your data's authenticity—not just its accuracy, but also its irreversibility. It can also be used to store data that are difficult to register, like legal contracts, state identifications, or a company's product inventory.
Blockchain has many advantages and disadvantages.
I’ll answer the most frequently asked questions about blockchain in this section.
Blockchain is not a cryptocurrency but a technology that makes cryptocurrencies possible. It's a digital ledger that records every transaction seamlessly.
Yes, blockchain can be theoretically hacked, but it is a complicated task to be achieved. A network of users constantly reviews it, which makes hacking the blockchain difficult.
Coinbase Global is currently the biggest blockchain company in the world. The company runs a commendable infrastructure, services, and technology for the digital currency economy.
Blockchain is a decentralized technology. It’s a chain of distributed ledgers connected with nodes. Each node can be any electronic device. Thus, one owns blockhain.
Bitcoin is a cryptocurrency, which is powered by Blockchain technology while Blockchain is a distributed ledger of cryptocurrency
Generally a database is a collection of data which can be stored and organized using a database management system. The people who have access to the database can view or edit the information stored there. The client-server network architecture is used to implement databases. whereas a blockchain is a growing list of records, called blocks, stored in a distributed system. Each block contains a cryptographic hash of the previous block, timestamp and transaction information. Modification of data is not allowed due to the design of the blockchain. The technology allows decentralized control and eliminates risks of data modification by other parties.
Blockchain has a wide spectrum of applications and, over the next 5-10 years, we will likely see it being integrated into all sorts of industries. From finance to healthcare, blockchain could revolutionize the way we store and share data. Although there is some hesitation to adopt blockchain systems right now, that won't be the case in 2022-2023 (and even less so in 2026). Once people become more comfortable with the technology and understand how it can work for them, owners, CEOs and entrepreneurs alike will be quick to leverage blockchain technology for their own gain.
