Firms can now apply for domains similar to their company name.
American Institute of Certified Public Accountants (AICPA) and its CPA.com unit have launched an application process for early access to .CPA domain names.
This process is different from sunrise and a separate non-Trademark-Clearinghouse trademark phase the organization is running.
Only CPA firms — not individual Certified Public Accountants — can apply during this early phase. Applicants who get a .CPA domain prior to general availability must put the domain to use by, at minimum, forwarding the domain to their existing website.
Applications for this phase must be received by October 31, 2020. The phase is only for registering domain names similar to the firm’s name, not generics like tax.cpa.
Domains will be allocated on a “systematic logic-based process”, according to the .CPA website. I inquired with a support agent about what this process is. The agent told me:
We have a process that we can’t share due to manipulation of the process. Please just choose domains that are most similar to your own.
It will be interesting to see how applications for the same name will be allocated.
Non-premium domain names cost $225 per year.
General Availability for .CPA begins January 15, 2021. At that point, any licensed CPA can register a domain.
Nomura’s jellyfish is a very large rhizostome jellyfish, in the same size class as the lion’s mane jellyfish, the largest cnidarian in the world. It is edible but not considered high quality. It is the only species in the monotypic genus Nemopilema.
Growing up to 2 m (6.6 ft) in diameter and weighing up to 200 kg (440 lb), Nomura’s jellyfish reside primarily in the waters between China and Japan, primarily centralized in the Yellow Sea and East China Sea. Population blooms appear to be increasing with frequency in the past 20 years. Possible reasons for the population increase in Nomura’s Jellyfish include climate change, overfishing, and coastal modification adding substrate for asexually producing polyps.
Jellyfish have two main types of muscle: epitheliomuscular cells and striated muscle cells. Researchers found that gene families that are closely associated with striated muscle were expressed in the bell portion of the jellyfish, providing evidence that striated muscle plays a significant role in jellyfish motility
The animals that can live forever
No one likes the thought of growing old. Despite our many human endeavours to escape or delay the process of ageing, it seems to be an inevitable part of life.
But … why? Why do living things gradually fall apart when they grow older?
There is a word for it: senescence. No, it’s not the rock band who sang ‘Bring Me to Life’; senescence is the state of gradual deterioration of normal functioning. At the cellular level, it means cells stop dividing and they eventually die. It can also apply to an entire organism (where a living thing can no longer respond adequately to outside stressors), or to specific organs or tissues (like leaves dying and falling from trees in autumn).
While there are ways we can slow down (or speed up) the rate at which senescence occurs, it is still going to happen one way or another. However, a few species can escape the ageing process completely.
The ‘immortal’ jellyfish, Turritopsis dohrnii
To date, there’s only one species that has been called ‘biologically immortal’: the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
A new jellyfish life begins with a fertilised egg, which grows into a larval stage called a planula. After a quick swim, the planula latches onto a surface (like a rock, or the ocean floor, or a boat’s hull), where it develops into a polyp: a tube-shaped structure with a mouth at one end and a kind of ‘foot’ at the other. It remains stuck in place for some time, growing into a little colony of polyps that share feeding tubes with each other.
Eventually, depending on the jellyfish species, one of these polyps will form an outgrowth called a ‘bud’, or it may produce separate segments stacked on top of one another, that can then break away from the rest of the colony. This process is responsible for the next stages of the jellyfish life cycle: the ephyra (a small jellyfish) and the medusa, which is the fully-formed adult stage capable of sexual reproduction.
For most other jellyfish, this stage is the end of the line. But Turritopsis dohrnii (and possibly some other jellyfish species too) has a neat party trick: when it faces some kind of environmental stress, like starvation or injury, it can revert back to being a tiny blob of tissue, which then changes back into the sexually immature polyp phase of life. It is a bit like a butterfly turning back into a caterpillar, or a frog becoming a tadpole again.
Of course, Turritops is dohrnii
Hydra look a bit similar to the polyp stage of a jellyfish (which makes some sense, given that jellyfish and Hydra are grouped together in the phylum Cnidaria): a tubular body with a tentacle-ringed mouth at one end and an adhesive foot at the other. They’re very simple animals that spend their days mostly staying in one place in freshwater ponds or rivers and using their stinging tentacles to grab any prey that happens to swim past.
Their claim to immortality? It seems as though they don’t go through senescence at all. Instead of gradually deteriorating over time, a Hydra’s stem cells have the capacity for infinite self-renewal. This seems to be thanks to a particular set of genes called FoxO genes, which are found in animals from worms to humans and play a role in regulating how long cells will live for.
In the case of Hydra’s stem cells, there seems to be an overabundance of FoxO gene expression. When researchers prevented FoxO genes from functioning, they found that Hydra’s cells began to show signs of ageing and would no longer regenerate as they did before. We still don’t know exactly how it all works, but we do know that these genes clearly play an important role in maintaining Hydra’s endless youthfulness.
Lobsters also do not experience senescence. Unlike Hydra’s reliance on particular genes, however, their longevity is thanks to them being able to endlessly repair their DNA.
Normally, during the process of DNA copying and cell division, the protective end-caps on chromosomes, called telomeres, slowly get shorter and shorter, and when they are too short, a cell enters senescence and can no longer keep dividing.
Lobsters don’t have this problem thanks to a never-ending supply of an enzyme called telomerase, which works to keep regenerating telomeres. They produce lots of this enzyme in all of their cells throughout their adult lives, allowing them to maintain youthful DNA indefinitely.
Telomerase is not unique to lobsters. It is present in most other animals, including humans, but after passing the embryonic life stage, levels of telomerase in most other cells decline and are not sufficient for constantly re-building telomeres.
Unfortunately for lobsters though, there’s a catch: they literally grow too big for their own shells. Lobsters continually grow larger and larger, but their shells can’t change size, meaning a lifetime of ditching too-small shells and growing a brand-new exoskeleton each time. That takes a fair amount of energy. Eventually, the amount of energy required to moult a shell and grow another new one is simply too much. The lobster succumbs to exhaustion, disease, predation or shell collapse.
There are many other animal (and non-animal!) species that offer tantalising glimpses into an ageless existence: the risk of dying for naked mole rats appears to not increase as they get older; the world’s oldest known non-colonial animal, a remarkably stress-resistant ocean-dwelling quahog clam named Ming, only died (accidentally) after a good 500 years when researchers dredged it up out of the ocean and wanted to find out how old it was; incredibly ancient bristlecone pines seem to function just as smoothly as much younger trees do; a particular colony of quaking aspens is considered to be about 80,000 years old … and there are plenty of other unusually long-lived species that seem to defy the passing of time.
Do they hold the key to eternal youthfulness for humans, too? We know that ageing in humans is thanks to a multitude of factors, many of which we still don’t entirely understand. Perhaps these examples from other species can shed some more light on those processes.
10 Cool things you didn’t know about jellyfish
1. Jellyfish are the oldest multicellular animals on the planet
Scientists have discovered jellyfish fossil snapshots in rocks believed to be more than 500 million years old. That makes them even older than dinosaurs!
2. Jellyfish don’t have brains
They don’t have a heart, lungs or a brain either! So how does a jellyfish live without these vital organs? Their skin is so thin that they can absorb oxygen right through it, so they don’t need lungs. They don’t have any blood so they don’t need a heart to pump it. And they respond to the changes in their environment around them using signals from a nerve net just below their epidermis – the outer layer of skin – that is sensitive to touch, so they don’t need a brain to process complex thoughts.
3. A jellyfish is called a Medusa
Jellyfish often look like a bell with tentacles all around the edge or hanging off the bottom. The shape of this bell is called a medusa because it looks like the evil Medusa in Greek mythology – a woman who had offended the goddess Athena who then changed her hair into snakes and made her face so hideous it turned people into stone. Medusa is also the word for jellyfish in many other languages including Greek, Hebrew and French.
4. Jellyfish can clone themselves
Imagine if you could just split in half and create a second version of yourself? If you cut a jellyfish in half, the pieces of the jellyfish can regenerate and turn into two new jellies.
5. Some jellyfish have teeth

The beroid comb jellyfish has hundreds of rows of “teeth” made of tiny hairs that can pierce, tear and pull their prey into their stomachs.
6. Jellyfish have gone into space

In 1991, moonfish jellyfish travelled into outer space on the Space Shuttle Columbia so that scientists could examine how microgravity affected them. The jellyfish multiplied in space. When they came back to Earth, the scientists discovered that the space-born jellyfish couldn’t figure out how to deal with gravity.
7. Jellyfish never get tangled
Even though some jellyfish have very long tentacles, they never get tangled up or sting them. That’s because the tentacles are very slippery and only sting other species of jellyfish.
8. Jellyfish can have super long tentacles

The lion’s mane jellyfish is the world’s largest jellyfish species. It can have tentacles that are over 27 meters long – longer than the size of the blue whale which is the biggest mammal in the world!
9. Jellyfish groups have a really awesome name
You might think that a gaggle of geese, a murder of crows, or a clowder of cats sounds interesting, but jellyfish groups have even better names. A group of jellyfish – which can include up to 300,000 jellyfish – is called a “bloom,” a “swarm” or a “smack.”
10. There’s not much to a jellyfish
Jellyfish are between 85% and 98% water. If they wash up on the beach they’ll almost disappear as their water evaporates.

An antivirus program (AV) is a piece of software designed to secure your desktop computer, notebook, netbook, Mac or mobile device from malicious software (more commonly called”malware”).
Malware — more on that later — is the title given to some piece of code designed to interrupt your system in some manner, be in the event for the purposes of causing you grief, stealing your money, or another sort of mischievous or criminal behavior.
Antivirus software is designed to thwart that threat, typically via signature-based detection procedures. Virus signatures are based on unique portions of code found inside the malware and are typically check-summed/hashed and dispersed in the kind of regular antivirus signature updates. To put it differently, researchers in the antivirus businesses delve into a new computer virus or other pieces of malicious applications, examine it and then inform their security applications what to watch out for in order to discover it.
Considering that the antivirus industry was created in the 1980s, the technology has come on leaps and bounds, primarily in reaction to the increasing number of threats.
When the internet was in its infancy, the number of viruses and other forms of malware were minuscule compared to now. Because of this, AV vendors could keep their clients safe simply by sending out updates monthly on floppy disks. Nowadays, the amount of threats is huge and malware appears every second of the day. Infrequent updates are no longer enough and hence the security programs of now offer near-continuous upgrades, often delivered through the cloud.
Additionally, the manner in which viruses have been detected has changed. Simply matching signatures isn’t sufficient to manage the evolving threat — contemporary antivirus programs now tend to integrate additional tools like behavioral-based detection and intrusion prevention technology.
Is it safe to use a computer or other device without having antivirus or other security program installed?
It is the answer I want to give to this question but the reality is that, for the huge majority of people, it actually isn’t a great idea to use an interconnected device without some type of security protection installed.
Sure, you’ve read or heard from security specialists who never install antivirus and never pick up any malware in their devices, but are you an expert?
If not, you’re going to be taking a massive risk with your information if you do not protect it.
And if you are not using Windows, that does not make you immune — just because Microsoft’s operating system was the most concentrated, it does not mean other operating systems are completely overlooked. Malware on the Mac, for example, really is something and it’s becoming increasingly prevalent.
So, whatever system you’re using, antivirus can help by radically reducing the odds of your system being infected with a virus, Trojan or other malicious code.
That is not to say that any antivirus program will provide you 100% protection against all present and future dangers — it won’t — since some malware is specially designed to circumvent security applications and/or make itself challenging to detect.
You can improve your chances of preventing viruses and other dangers though. Here are some quick tips:
- Pick an antivirus program that is highly regarded by independent testing labs like AV-TEST and AV-Comparatives.
- Make certain your antivirus program updates regularly — at least once daily is advised. The same goes for your operating system — if security upgrades are available, install them immediately
- Run complete scans on a regular basis. Most antivirus programs will assess recently installed apps but a complete scan can help detect anything that may have sneaked past your defenses
- Pay attention to your computer — if it starts behaving strangely, functioning slowly, or you begin seeing a lot of web advertisers.com.ng
Can a free antivirus program offer adequate protection?
There is an old adage that says you get what you pay for and in the event of antivirus software that is kind of true.
That is not to say free antivirus applications ought to be dismissed out of hand, however — some are really very good and might well be adequate for some people.
Concerning independent testing, AV-Test. Org results over a time period show that free antivirus programs do, overall, score lower than the paid-for alternatives in the market and our own experience has taught us that free programs also tend to suffer from a lack of additional attributes, less than stellar support, an obsession with up-selling, or a combination of all three.
Whether or not some of these issues are a deal-breaker for you will probably depend upon what you use your computer for, how you value your data and your personal financial situation.
In any event, installing any antivirus program is preferable to having none at all, though you really do need to be watching out for free imitation antivirus programs which are better than the viruses that they want to prevent in the first location.
What is the best antivirus to use?
I’m afraid I can’t just name a single product and let you go get it — antivirus is a personal choice and the best for you is very likely to be the one which provides the features you want and works nicely on your system when coming in at a price point that is suitable for your budget.
Having said that, you’ll most likely need to stick to software given by the biggest, most well-known, firms in the market, such as BitDefender, ESET, F-Secure, Kaspersky, McAfee, Symantec and Trend Micro, to mention but a few.
Something we can’t stress strongly enough is to do your research before purchasing or downloading an antivirus program.
They aren’t created equal and odds are you will use the identical program for at least a year so it is important to make an informed decision.
To begin, you’ll have to narrow down your search to antivirus programs that are compatible with your operating system. If you’re using Windows that will leave you with a far bigger pool that if you’re using a Mac or Linux so you’ll have to add in more standards.
Are you, by way of instance, a heavy gamer that will want to have an antivirus application that’s either light on resources or that has the capacity to suspend scans during gaming time? Are you an occasional surfer who never logs to sensitive websites or stores personal data in their own machine, thus creating a free antivirus program an attractive proposition?
When you have assessed your needs and paired programs for your operating system then you’ll have to narrow things further by assessing independent laboratory results, focusing mostly on detection and elimination scores.
Once you have identified your top two or three choices it is time to read detailed reviews that give an honest assessment of each program’s pros and cons, along with the comments left by other owners of the same software
Only then can you make an educated decision on which antivirus program will be ideal for you’re unique circumstance.
