Climate change has intensified the risks we face in places like Lowestoft, left without adequate flood defences, writes Kate Stott
Rachel Keenan’s account of the rapid and ongoing destruction of her home town of Inverbervie, Aberdeenshire, is stark, but sadly she is not alone (‘The fear has properly set in’: how it feels to watch my home town disappear into the sea, 21 May).
Here in Lowestoft, Suffolk, the tidal surge resulting from December 2013’s Storm Xaver left 158 homes and 233 commercial properties flooded, with many people made homeless. In response, improved floodwalls were completed in 2023, but in January 2024 the plug was pulled on the construction of a tidal barrier due to the emergence of a £124m funding gap. Instead of a flood defence system, Lowestoft has therefore been left with what worryingly looks a lot like a funnel.

Facilities belonging to some of the leading commercial laboratory companies in Australia were among those that retested samples of landscaping products at the request of their waste company clients, after initial tests found contamination not compliant with NSW laws.
Guardian Australia revealed earlier this year the testing regime meant to limit toxic chemicals in landscaping material known as “recovered fines” had been compromised by the practice of waste companies asking private laboratories to retest samples until they passed.

Rivers, lakes and tap water in areas of Bangladesh that host garment factories are swarming with dangerous levels of toxic “forever chemicals”, some with links to serious health issues, according to new research.
In the first study of its kind conducted in Bangladesh, a global fashion hub supplying international brands, per- and polyfluoroalkyl substances (PFAS), commonly known as forever chemicals, were found in 27 water samples collected close to textile factories in the capital, Dhaka.

The next government should force all tradespeople who install home heat pumps, solar panels and insulation to sign up to a mandatory accreditation scheme to counter mistrust in the industry, a leading consumer group is demanding.
A report from Which? found that households face “significant anxiety” in choosing tradespeople to fit low-carbon heating systems, such as heat pumps, and insulation after “press stories about poor work and rogue traders”.

Continue reading...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.

What if the jury convicts Donald Trump? It would present an unprecedented test of America’s political system, and also the bureaucracy that deals with convicts in New York state, the Guardian’s Sam Levine reports:
If a Manhattan jury convicts Donald Trump on any of the 34 counts of falsifying business records in the hush-money case, the immediate next question will be what punishment the former president should receive.
Donald Trump’s criminal hush-money trial in New York inched towards its conclusion on Wednesday with jury deliberations starting just before 11.30am local time.
Before the start of deliberations, Judge Juan Merchan instructed jurors . Merchan’s directives on the law were intended to guide jurors about how they are supposed to weigh the case.

South Africans are voting in what are expected to be the most competitive elections since the end of apartheid, which could result in the ruling African National Congress (ANC) party losing its majority for the first time since Nelson Mandela led it to power 30 years ago.
The national mood is grim owing to some of the world’s highest rates of unemployment and inequality, power cuts, water shortages and violent crime. Younger generations do not feel the same gratitude and loyalty to the ANC as many of their parents and grandparents do, for leading the successful fight for multi-racial democracy.

Australian scientists have developed a method of brewing coffee by blasting ground beans with sound waves – and it produces a powerful cup
I’m looking at a coffee that’s thick, cold and the deep brown colour of 90% dark chocolate. It tastes like coffee but, weirdly, without any bitterness. It is the only coffee I’ve had that was made by blasting ground coffee beans with sound. They call it ultrasonic coffee.
It wasn’t made by a barista but by two chemical engineers in a lab at the University of New South Wales in Sydney. Dr Francisco Trujillo, a senior lecturer in the school of chemical engineering, and the PhD student Nikunj Naliyadhara explain the coffee they’re about to make is sonicated, or hit with ultrasonic waves. I have no idea what that means. But they grind coffee beans, pack them into a portafilter basket (the handled device you’ve probably seen your barista twist and untwist) and connect the portafilter to a Breville espresso machine. And just like your barista, they press some buttons. The machine makes soft whirring sounds.

South Africa's case against Israel over allegations of genocide before the international court of justice has raised a central question of international law: what is genocide and how do you prove it?

Josh Toussaint-Strauss looks back on these historical cases to find out why the crime is so much harder to prove than other atrocities, and what bearing this has on South Africa's case against Israel and future cases

You don’t really ever need extra reasons to visit Denmark, but the country’s sheer variety of cultural highlights looks set to enliven any stay this year
Stargazing, seals and sandbanks in Mandø
Denmark’s wilderness zones and sparsely populated isles have long been havens for nature lovers and stargazers. Mandø, on the south-west coast of Jutland, is the most recent addition to the country’s four Dark Sky Parks. A small island in the Wadden Sea National Park, Mandø is most easily accessed at low tide via tractor bus over the causeway from the mainland – adding to the adventure and reducing the chances of latecomers’ annoying car headlights ruining your night vision. By day, you’ll likely want to visit the lovingly preserved, thatched and white-walled Mandø House museum (an early 19th-century shipmaster’s home), not to mention the island’s landmark windmill and church. Observe thriving seal and migratory bird species on a bike ride around the marshes and sandbanks.

With a beautifully appointed gallery of vintage bottles, a stable with draught horses that hark back to the days of carts hauling barrels through Copenhagen’s cobbled streets, and tasting sessions too, if you’re in Copenhagen and you love beer, this is one not to be missed. Definitely.

Continue reading...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.
