Discovery Alert: An Earth-sized World and Its Ultra-cool Star
Wed, 15 May 2024 16:32:40 +0000
Our galaxy is a jewel box of red stars. More than 70% of the stars in the Milky Way are M dwarfs, also known as red dwarfs. These stars are cool and dim compared with our Sun, but they often blast orbiting exoplanets with high-energy radiation, especially early in their lives. And those ‘‘lives’’ last […]

A Guardian survey of leading climate scientists revealed their despair about the future. John Coghlan, Rachael Orr, Natalie Bennett, Dr Robin Russell-Jones and Gregory Johnson find reasons to keep on fighting
I must commend the Guardian and Damian Carrington for the excellent reporting on the views of leading climate scientists (‘Hopeless and broken’ Why the world’s top climate scientists are in despair, 8 May). I have experienced climate despair, which has led me to take part in non-violent protests, and I can certainly bear witness to the fact that this kind of collective action goes a long way to offset the despair. However, protest is not for everyone. There are other ways to play our part.
We can help to accelerate the energy transition. Some 51% of final energy consumption is for heating and cooling, and 32% is for transport, according to the International Energy Agency, so we must ditch the old boiler and invest in a heat pump, and swap our petrol car for an electric model. By fitting solar panels, we can also generate renewable energy to power both transport and heating. Having done these things myself, I have found that the lightening of my carbon footprint brings with it a lightening of climate despair.

Beverly Lofton’s home in south Los Angeles used to have a water-guzzling grass lawn. Today, it’s a verdant microfarm that uses solar power and recycled water to grow carrots, beets, potatoes and more, with the bounty distributed to her neighbors. The 67-year-old’s switch was a bold move in a city ruled by cars and concrete, and where the impact of extreme heat and water shortages are acutely felt. It’s also a powerful rebuttal to food insecurity and big agriculture, in a neighborhood considered a “food desert”.

When it comes to heating our homes efficiently, the UK is lagging behind our European neighbours, however, there are ways in which we can better insulate and save money
Whether it’s squabbles over the office air conditioning or a family member telling you to put on another jumper, heating has always been a hot topic. However, with rising energy costs and the pressing climate crisis at the front of everyone’s mind, how we keep our homes warm is getting even more attention. While we might crave that satisfying feeling of nearly scalding our hand on a radiator when we crank up our central heating, we need to adopt a new mindset.
The UK is still very much reliant on fossil fuels for heating our homes. At the same time, reduction of fossil fuel usage is the number one priority when it comes to combating climate change, meaning the way we heat our homes is long overdue for an overhaul. In England, 90% of homes (pdf) have a boiler system with radiators as their main form of heating, while across the UK, 25m gas boilers are in use, which accounts to 16% of the nation’s total greenhouse gas emissions. To put it into perspective, for the UK to meet the government’s net zero target by 2050, about 8m buildings will need to switch from gas boilers to cleaner alternatives by 2035.
Continue reading...When you heat your home efficiently, you can stay cosy and warm without damaging your purse or the environment. However, knowing exactly how to heat your home is key, and here we bust some myths so you can reap the full benefits …
Myth 1: The ideal room temperature is 21C
We often keep our homes warmer than necessary. While a few degrees might not sound like much, it makes a big difference in terms of the overall energy output and cost. We might think we need our home to be set to around 21C, but in reality a little lower is more than sufficient. The World Health Organization suggests 18C is the ideal room temperature for healthy and appropriately dressed people, while The Sleep Charity recommends a bedtime temperature between 16C and 18C for optimum sleep.
Myth 2: Boilers are the most efficient way to heat your home
While in the UK many of us have relied on traditional gas boilers for generations, our European neighbours have been switching to heat pumps. These home heating devices are a modern, low-carbon and economical solution for creating a cosy home. Working much like a fridge or air conditioning unit, they use evaporation and condensation to create heat energy without the need for any fossil fuels.
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.
