NASA Langley’s Legacy of Landing
Thu, 03 Apr 2025 14:19:05 +0000
Landing safely on the surface of another planetary body, like the Moon or Mars, is one of the most important milestones of any given space mission. From the very beginning, NASA’s Langley Research Center has been at the heart of the entry, descent and landing (EDL) research that enables our exploration. Today, NASA Langley’s legacy […]

What Are the Dangers of Going to Space? We Asked a NASA Expert: Episode 55
Wed, 02 Apr 2025 19:50:20 +0000
What are the dangers of going to space? For human spaceflight, the first thing I think about is the astronauts actually strapping themselves to a rocket. And if that isn’t dangerous enough, once they launch and they’re out into space in deep exploration, we have to worry about radiation. Radiation is coming at them from […]

Luton airport allowed to double capacity after UK government overrules planners
Thu, 03 Apr 2025 13:09:03 GMT
Transport secretary Heidi Alexander grants consent to London’s fourth-biggest airport to allow potential 32m passengers a year
Luton airport will be allowed to almost double in capacity after the government overruled planning inspectors who recommended blocking the scheme on environmental grounds.
The transport secretary, Heidi Alexander, granted a development consent order for the airport’s plans to expand its perimeter and add a new terminal, allowing for a potential 32 million passengers a year.

A megafarm that would have reared almost 900,000 chickens and pigs at any one time has been blocked by councillors in Norfolk over climate change and environmental concerns.
Councillors on King’s Lynn and West Norfolk borough council unanimously rejected an application to build what would have been one of the largest industrial poultry and pig units in Europe.

Serpentine, London
From the moment we inhale the scent of this remarkable show – in which trees blast open and boulders perch on branches – the Italian artist intoxicates us like a shaman communing with wood sprites
It’s the aroma that lures you in. Deep and difficult to place, it comes from the thousands of laurel leaves that pad the walls of the Serpentine’s high central space. Laurel is the sharp-leaved evergreen tree sacred to the god Apollo and through him associated with victory and the arts. Poets are crowned with it. In Botticelli’s Primavera, a nymph is chased through laurel trees. A marble sculpture by Gian Lorenzo Bernini depicts Daphne transforming into a laurel to escape Apollo’s unwanted lust – a reason this tree is sacred to him.
So much cultural baggage. It can’t be easy to be a modern Italian artist with ancient Rome, the Renaissance and the baroque on your back. One of the captivating things about Giuseppe Penone’s meditative selection of his works is how easily this artist has cast off that weight of tradition ever since he started his life in art in 1968.

Three or four years ago, the Spanish psychologist Jesús Moreno began to notice a difference in the drawings that the young participants in his workshops on masculinity produced when asked to sketch out their idea of what a man looks like.
The figures they drew were no longer merely the muscular and bizarrely well-endowed drug dealers, etched with prison tattoos and surrounded by guns, knives, cars, sex workers and bundles of cash, to which Moreno and his colleagues had long grown accustomed.

Everyone is talking about Adolescence, the television drama focused on toxic masculinity that has triggered a continuing social and political debate. But only a handful of people are talking about what the hit drama says about the real-time crisis unfolding in the British television industry – and that needs discussion too.
Adolescence is everything public service broadcasting should be: hard-hitting programming featuring the kind of people often ignored in TV drama – in this case, white working-class families in the north – discussed at the school gate and in parliament. After its British writer, Jack Thorne, met Keir Starmer in Downing Street, it was revealed that Adolescence was to be rolled out for free across all UK secondary schools.

Good morning. On Tuesday, Israeli defence minister, Israel Katz, announced a major expansion of attacks on Gaza and the “capture of large areas that will be added to the security zones of the state of Israel”.
The announcement followed a night of airstrikes on Khan Younis and Rafah in southern Gaza, which officials said had killed at least 21 people, including a pregnant woman. The intensification of Israel’s offensive comes after more than two weeks of airstrikes and ground operations that have, according to Gaza’s health ministry, killed more than 900 people. Unicef has said that at least 322 of those killed since the renewed attacks have been children.
UK economy | Donald Trump has hit the UK with tariffs of 10% on exports to the US as he ignited a global trade war. Other tariffs include 20% on the EU and 34% on China. Downing Street had been expecting 20% but Keir Starmer’s conciliation towards the Trump administration appeared to have paid off.
Immigration | An investigation has been launched after a racist message was reportedly “blasted out” on portable radios used by Home Office contractors at an asylum processing centre. The deeply offensive broadcast – “fuck off you [N-word]s, go back to where you came from” – was reportedly heard at the Manston processing site for small boat arrivals in Kent.
Health | Doctors have reported a rise in the number of patients with Victorian diseases such as scabies, as the Royal College of Physicians urged the government to do more to fight poverty.
UK news | A third former South Yorkshire police officer has been arrested as part of an investigation into child sexual exploitation in Rotherham. The ex-constable, aged in his 50s, was arrested on Monday on suspicion of raping a teenage girl in the town in 2004.
Education | The fate of boys “is a defining issue of our time”, according to the education secretary, Bridget Phillipson, as she calls for more men to become teachers to combat “toxic” behaviours.

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.

In the aftermath of the disastrous debate against Donald Trump that ultimately ended his political career, Joe Biden skipped a White House meeting with the congressional Progressive caucus in favor of a Camp David photoshoot with the fashion photographer Annie Leibovitz, a new book says.
“You need to cancel that,” Ron Klain, Biden’s former chief of staff and debate prep leader, told the president, as he advocated securing the endorsement of the group of powerful progressive politicians perhaps key to his remaining the Democratic nominee.
Continue reading...Conformity and fear of party leadership are impairing Democrats’ ability to fight Trump and drive a progressive agenda
Joe Biden’s insistence on running for re-election was certainly disastrous. It kept credible contenders out of the Democratic presidential primaries and prevented the selection of a nominee who had gained momentum in the winnowing process. Even after his stunningly feeble debate performance on 27 June last year, Biden took several weeks before finally opting out of the race. That left Kamala Harris a mere 107 days between the launch of her campaign and election day.
Ample evidence shows that the Biden team was riddled with obstinate denial and misrepresentation aimed at the public. But tales of tragic egomania in high places can take us only so far. What’s essential is to scrutinize how – and why – the Democratic party, its leaders and its prominent supporters enabled Biden and his inner circle to get away with such momentous stonewalling for so long.

From 1862 until 1923, US senators and members of Congress provided vast numbers of seeds to constituents. At its peak, the congressional seed distribution program delivered over 60m seed packets directly to farmers and market gardeners every year, helping introduce new varieties of everything from wheat and corn to oats, soybeans, flowers and vegetables. A century later, far fewer Americans till the soil for a living, but seeds remain central to our lives.
To understand the importance of seeds, try to imagine a morning without them. It would begin naked on a bare mattress, with no cozy sheets or pajamas, and there would be no fluffy towel to wrap up in after your shower. All of those things come from the seeds of the cotton plant. Stumbling wet into the kitchen, you would find no coffee, and no toast or bagel to go with it. There would be no eggs, no bacon, no cereal, no milk. All of those staples come from seeds or from livestock raised on seed crops. And if you thought you might console yourself with a chocolate bar, you can forget it. Cocoa powder, and the cocoa butter that makes it melt in your mouth, are both derived from seeds.

Archie Norman, the chair of M&S, has described Percy as the retailer’s “gift to America” but he told the Retail Technology Show in London that “we might have to change our minds” as Trump imposes additional taxes on imported goods. While M&S is not considering withdrawing the sweets, tariffs could push up prices and make them less popular.

It’s a nice story – but it’s not the whole story. Look closer and the plaque states that the first Pret sandwich shop opened “near here”. In fact, it was down the road, at 75b, now a branch of Toni & Guy. Except … that wasn’t the first shop, either. The original Pret opened two years earlier and five miles to the north, in Hampstead. It went bust after a year and the founder, Jeffrey Hyman, sold the name, branding and logo to Julian Metcalfe and Sinclair Beecham, who reopened in Westminster.

• The best rice cookers for gloriously fluffy grains at home
Coconut milk is always found front and centre in my pantry because it is a cornerstone of so much of my cooking. I buy it in bulk and rely on it to bring a voluptuous, fragrant, dairy-free creaminess to so many of my favourite dishes, from curries and dals to soups and rice dishes. It’s also indispensable for puddings for vegan friends, and for my sweet-toothed, lactose-intolerant husband. It mellows out spices and pulls a dish together, adding a silkiness to sauces and a sweet, nutty richness to cakes, batters and vegan custards.
I appreciate the convenience of the canned stuff because making coconut milk from scratch, as my mother used to do when I was growing up in Kenya, is laborious: a mature brown coconut has to be broken, its flesh grated, then soaked in hot water, before being strained and squeezed several times through a cheesecloth.

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.
