Suggested March 2024 Are Screensavers Necessary And Still Needed?
Screensavers are a visual treat and there are plenty available all over the Internet. But are Screensavers necessary anymore? A screensaver is basically nothing but a computer program that fills the screen with images or abstract patterns. It gets activated when the computer is not in use for a particular period of time. The idea behind this originally was to prevent phosphor burn-in on Cathode Ray Tube and Plasma monitors. But since now most of us use LCD monitors, they are used mainly for entertainment or security purposes.Are Screensavers necessary anymore?
Colorful and animated screensavers look good to the eye and sometimes give you a feeling of freshness and fill you with enthusiasm. Back in the 90s and 2000s, they were in abundance and the beautifully animated ones were a craze. Back then, they were necessary too, because of the CRT monitors. But as we moved towards LCD monitors, are the screensavers are activated for security purposes mainly.Purpose of Screensavers
The working method of CRT (Cathode Ray Tube) monitors made it necessary to have an object always moving on the screen. The CRT monitors used a gun that focused rays to different phosphorus pixel centers on the back of CRT screens and used to hit them. The phosphorus points were heated upon hit and produced light. Several hits all over the screen backside produced heat that converted into light to show us images on the screen.
If an image was left still, the cathode ray gun would hit the same phosphorus points again and again to retain the image. Since light was produced by heat, in those circumstances, the possibility of creating a permanent burn was high and hence screensavers were introduced. Screensavers used to make the gun hit different phosphor points as long as the screensavers were always moving.
One can argue why not simply turn OFF the monitor if not in use for a while. But the CRT monitors pulled a heavy load of electricity when turned ON. This was a reason why turning off CRT monitors was not recommended unless you were sure you won’t be using the computers for more than an hour or so.
Thus, with CRT monitors, the screensavers were a necessity as they prevented screen burn and saved energy, by way of keeping monitors ON. However, since most of us now use LCD screens, there is no real use for screensavers.Are Screensavers still needed?
If you are using an LCD monitor, you do not need screensaver. It is a different thing that some computer users still prefer visual treats and hence install good screensavers. Some prefer to have the screensaver activated when they are away from the screen and require them to logon again. Yet others may like to use a screensaver which will display some system information.
With LCD (Liquid Crystal Display) monitors, there are no phosphors involved. Though the heat is there, it is not as much as the one created by CRT gun.
The images are created on an LCD monitor by aligning liquid crystals in different forms using electricity. The rear side of LCD monitor is also a screen containing liquid crystals. The crystals are arranged in a specific format and heated a little to produce light that in turn, produce image on the screen.
Since the heat is not much, you can keep a static image on the LCD screen for a considerable period of time without harming the screen. But keeping a static image consumes energy, so it is better to turn off the monitor as long as you are not using it. Unlike CRT monitors, there is no heavy pull of electricity when the screen is turned ON. So you can use the Windows Power Options to turn it off after a while of inactivity and turn it on simply by moving mouse or pressing any key. Screensavers are therefore not required anymore.Save Battery Instead
Some people still use screensavers for fun, but that is entirely their choice and not a necessity. Using screensavers means keeping the screen ON. In the ON state, monitor drains off energy. In this age where we depend on battery life, saving each unit of energy is a necessity. It is always better to turn off the screen when it is not in use and later turn it on when required. That will pretty much save a lot of your battery juice.
Hence to conclude, the answer to “Are screensavers necessary and still needed” depends on the following:
Yes, if you are using a CRT monitor of the 90s and 2000s;
No, if you are using a modern computer monitor or integrated screens built into tablets and smartphones.
Yes, if you like to see them.

Another week has passed by and the one-year anniversary of COVID-19 being officially declared a pandemic is creeping closer. And while case counts are going down across the world, the longer the pandemic lasts, the more chances the virus has to mutate, which could influence how well we can control the virus. Here’s what to know today about the battle against COVID-19.A new COVID-19 variant has popped up in New York City
COVID-19 first hit New York City hard in the spring of 2023. And while things may seem more under control than months prior, the worrying issue of tougher, more resilient variants still lingers. In particular, one new variant that now accounts for over one in four sequenced cases of COVID-19, is now spreading rapidly throughout the city according to two new research studies.
The new variant, named B.1.526, contains mutations such as the E484K mutation seen in the Brazil and South Africa variants. Further, some contain S477N which could have an impact on how well the virus binds to human cells. On average, the patients with the B.1.526 strain were six years older and many were located in communities nearby hospitals, according to The New York Times. And while some experts say that people who have recovered or been vaccinated will likely be able to fight this variant off, it is definitely still something to watch.
“It’s not particularly happy news,” Michel Nussenzweig, an immunologist at Rockefeller University, told the New York Times. “But just knowing about it is good because then we can perhaps do something about it.”Life in our COVID-19 bubbles could change how we react to other viruses
When you work from home, socialize from home, get groceries delivered to your home, and hardly travel, the range of germs you come in contact with shrinks. And when it comes to avoiding COVID-19, that’s what needs to be done, but our immune systems are getting less and less used to those everyday germs that could give us run-of-the-mill colds and sniffles.
One recent study showed that upper respiratory infections rose dramatically right after schools and daycares reopened in Hong Kong, despite strict COVID precautions, like masks, regular cleanings, and so forth being put in place. After a deeper look, the researchers learned that it wasn’t COVID-19 or the flu that was the culprit for the burst of runny noses, but instead rhinoviruses and enteroviruses which are more likely to cause a case of the common cold.
What this more or less means is that while cooped up at home, our susceptibility to rhinoviruses and other respiratory illnesses may have increased thanks to social distancing and other measures. When confronted with these same germs when school started back up, transmission powered up as well. So when we return to school and regular life, we might not be as prepared (not to mention, masks and disinfection techniques aren’t as protective against viruses that aren’t coronaviruses or influenza).
“Our findings highlight the increased risk posed by common cold viruses in locations where schools have been closed or dismissed for extended periods during the COVID-19 pandemic,” the authors of the study write.

The biggest no-no when it comes to COVID-19 spread is being in a crowded room with other people breathing heavily on each other. And if you are a gym-frequenter, you’ll know there’s a lot of heavy breathing done during a workout, whether you’re alone, in a group, doing weights, or using cardio equipment. And it’s no secret that gyms can be a hotbed for spreading illness.
Still, gym-related COVID-19 outbreaks are still being discovered—one gym in Chicago operating at 25 percent capacity over the summer sickened 55 people. Most of the gym attendees did not keep masks on leading up to this outbreak, and three people who attended had just tested positive for the virus before working out. One trainer in Honolulu initiated a cluster of 21 positive cases by teaching classes at three separate gyms, while still trying to wear masks and socially distance.
The moral of the story is to keep your exercise to your living room or outdoors for the time being. “If you can wait until the spring and work out outside, it will be a lot safer,” Joshua Epstein, an epidemiology professor at NYU’s School of Global Public Health, told The Washington Post. “We are not out of the woods by any means. It’s not the time to relax.”
Do you want to know how well your website performs in search engines? If so, you are not alone. Each digital marketing plan should include search engine optimization (SEO), but doing it well may be difficult. The rank penalty happens when search engines penalize websites for breaking their rules or participating in unethical practices.Now Let’s Understand What Rank Penalty is and Why Should We Avoid It
The Rank Penalty is a punishment that search engines apply on websites that disobey its rules or use black-hat SEO techniques like keyword stuffing, spoofing, or purchasing links. As a result of being punished, a website’s search engine ranks may dramatically decline, making it more challenging for people to locate the site and lowering its exposure and traffic. It’s crucial to stick to search engine guidelines, emphasizes producing high-quality content, and employ ethical SEO techniques to prevent the rank penalty. By doing this, you may increase your website’s exposure, draw in more visitors, and evade the drawbacks of a rank penalty.Key Steps to Be Considered in Order to Avoid the Rank Penalty

Whenever you do anything on the internet, you’re being tracked. As a recent segment on Last Week Tonight with John Oliver explains, there is a lot of money to be made from widespread data harvesting. It can be used to sell products, target potential voters, and even just scam people.
Apple was the first major consumer tech company to position itself as privacy-first. Its Safari browser has blocked some third-party cookies since 2023 and all third-party cookies since 2023. In 2023, it also introduced a feature where apps would have to ask for explicit permission from users to track them. (Facebook parent company Meta has claimed this last update alone will cost Facebook $10 billion in lost revenue this year).
[Related: DuckDuckGo’s new Mac browser aims to put privacy first]
Firefox has also blocked some third-party cookies since 2023, and unveiled Total Cookie Protection in 2023 which consigns each site’s cookies to its own separate “cookie jar,” which bars information from being shared with other websites. There has also been a rise in privacy browsers, like those from DuckDuckGo and Brave, that take an even more aggressive stance on blocking tracking. Both use their own custom search engines as well as other privacy focused features like easy data deletion to limit how much data can be gleaned from your browsing activities.
Even Google is getting in on the action. It will start blocking third-party cookies in its Chrome browser (the most popular browser in the world) in 2023—although that is about a year later than was initially planned.
For all this, internet tracking isn’t going away. The methods are just going to change. For example, Google announced that it is replacing cookies with a new feature called “Topics.” And, as an article in The New York Times speculates, the current fixes might serve entrenched interests best, rather than consumers or smaller businesses. With third-party tracking curtailed, it might be harder to track users as they move around different apps and services, but not if they stay within the same ecosystem. If you’re logged into your Google account in Google Chrome, using Google to search the internet, and watching videos on YouTube, Google doesn’t need cookies to track you—it has plenty of data already linked to your account. Similarly, while Apple largely blocks third-parties from gathering data about its users, it still has access to a spectacular amount of information. Meta’s Facebook and Instagram won’t be able to track what you look at on Amazon, but they still have a record of who you follow and interact with. The big tech companies, it seems, will be in the strongest position going forward.
All this is still up in the air, though. Internet tracking is in a transitional phase. The European Union is levying increasingly large fines for breaches of its General Data Protection Regulation (GDPR) laws, which might start to skew the risk calculus for some companies. Efforts are also underway to block these new forms of tracking—both DuckDuckGo and Brave have just announced that their browsers will bypass Google’s AMP pages, one of the ways that Google has leveraged its size to further track users. Internet tracking is definitely going to continue but, fingers-crossed, it might get better.
In the late winter sun, Yellowstone National Park‘s blanket of snow is blindingly white. The great shaggy beasts—bison, in their thick, burnished winter coats—thrive in the glare. A few yards from where I stand on the road, a small group is gathered, sweeping their upturned horns from side to side, grunting softly as they plow away the snow to graze. I’m transfixed, so it takes a minute to notice the hundred or so more scattered in the valley ahead of me. Across the steep rise of the Gallatin Range, bushes dotting the ridge come into focus; each, I realize, is a buffalo, lumbering out of the mountains toward lower elevation.
Each winter, Yellowstone’s bison move from the high country in groups of a few dozen, seeking better feeding grounds. The evidence of wild bison migration is etched into our continent, where the movement of vast herds shaped the land. The countless pounding hooves formed wide passages called buffalo traces, as the beasts followed watersheds and ridgelines to new territory. The early pioneers followed these paths—through the Cumberland Gap in the Blue Ridge Mountains, across the Ohio River near Louisville, and the Vincennes trace through Indiana and Illinois—to settle the West.
Of course, these places have long been purged of wild buffalo. By the 20th century, westward-moving colonizers, a thriving hide-hunting trade, and efforts to wipe out native populations by diminishing their primary food source had reduced a teeming mass of tens of millions of bison to just 23 fugitives, holed up in a valley a few miles south of where I glimpsed my first Yellowstone grazer.
Today, the American buffalo is one of the environmentalist movements’ great success stories. Thanks to more than a century of conservation efforts, there are roughly half a million bison in the United States, though they live strikingly different lives than their ancestors. More than 96 percent are livestock, raised for meat. The remainder, about 19,000, are mostly behind fences, in managed herds across the country.
Yellowstone’s bison are different. The animals that occupy the park are the last of their kind. They exist as their forebears did, in this tiny sliver of the U.S. where they’ve never been extirpated. They fight, graze, and repopulate without the help of humans. They fall through thin ice and drown in lakes and rivers. They lose their old and sick to grizzly bears and wolves. And in winter, when the grass dwindles, they get going, roaming across the reserve’s 2.2 million acres, an area far less than 1 percent of their historic range. They are America’s last truly wild bison.
That wildness is what makes them iconic. In 2024, President Obama named the bison our first national mammal. They appear on the seals and flags of five states, and bring in hundreds of millions in tourism dollars every year. But scientists and conservationists warn that the Yellowstone bison are approaching a precipice—a moment that may make it nearly impossible to preserve their untamed nature.
For the ranchers and civilians who live on the park’s outskirts, migrating bison have never been convenient, but an infectious disease has heightened tensions. Scientists estimate that more than half of Yellowstone’s female bison herd carry brucellosis, a bacterial infection that causes domestic cows to abort their fetal calves. Though there’s never been a documented case of transfer from bison to cattle, theoretically the disease could spread to the herds that graze on public lands outside the park. Since 2000, the Department of Livestock for the state of Montana, which controls the land north of the park, has had an agreement with Yellowstone officials, the U.S. Department of Agriculture, and tribal entities: Inside the park, the bison are free to move as they please; once they go beyond the boundary, they’re fair game. Some are killed by hunters and local tribes. More are captured by wildlife managers and sent to slaughter. Almost none of the bison that attempt to migrate beyond Yellowstone’s borders survive.
Humans have played a role in natural selection since the first hunter threw a spear. But wildlife biologist and retired Colorado State professor James Bailey warns that by culling the migrating bison, and therefore selecting for the trait of staying put, we might be “disorganizing and diminishing the wild, adaptive genome.” He acknowledges that the proximity of people to places like Yellowstone makes some intervention necessary, though he calls the field he taught for 20 years—wildlife management—an oxymoron. But already, there are serious consequences.
“People are always looking for a number,” he says. “How many do we need? How much genetic diversity? How much natural selection? All these lines are largely arbitrary, so there’s no value in waiting for an absolute answer. Meanwhile, it’s business as usual, which is degrading the wildness of our herd.”
The animals in conservation herds will keep the species safe from extinction, but if we domesticate the mobility out of this last wild group, the ecology of the landscape will suffer, perhaps irretrievably, and we will have lost our wild buffalo after all.
In the American imagination, the West has often been a cattleman’s paradise. In reality, that land has always belonged to the bison. Within their habitat—a range that once stretched across at least 40 states—the bison is a keystone species, on which nearly everything else in the ecosystem depends.
End of he Roam
At Stephens Creek Capture Facility, staff send straying bison to slaughter.
As they graze, their hooves and horns turn the soil, planting seeds and creating pockets of moisture that encourage growth. When they shed hair, small mammals and grassland birds use it to insulate their nests. Wallows, the depressions bison form by rolling in the dirt, fill with water and create miniature pond habitats for insects and frogs. Over millennia this mutually beneficial coevolution has built an ecosystem in which the buffalo—and their ability to roam—are vital.
Then, we nearly wiped them out, and replaced them with cows.
In the late 19th century, after tanneries developed a process for making hides into leather, bison slaughter peaked. Hunters killed an estimated 2 million in 1870. For the next three years, hide hunters took down roughly 5,000 buffalo every day. By mid-1883, almost every single bison in the U.S. was dead.
In contrast, bison are built to survive. They “will eat snow, search out tiny springs, even paw the earth for water,” writes Dan O’Brien, a rancher in South Dakota, in his book, Buffalo for the Broken Heart, a memoir about converting his cattle operation to a free-range bison ranch. The diversity of their diet “allows them to roam many miles from major sources of water. That difference between cattle and buffalo is obvious enough for anyone to see.”
We’ll never glimpse our nation’s landscape as it might have looked had the bison survived, but thanks to Yellowstone, we can make a pretty good guess. Chris Geremia, the park’s soft-spoken, bespectacled lead bison biologist, says the herd shapes the local ecology in a way other large ungulates—pronghorn, deer, sheep, and elk—do not. As temperatures begin to climb in the spring, all the animals “surf the green wave,” moving from low to high elevations as grasses and plants emerge. Unlike the other species, though, buffalo stop surfing in mid-spring, gathering in huge numbers in central areas they turn into grazing lawns.
“They look just like a lawn in the suburbs,” Geremia says. At the end of the season, pastures where domestic cattle graze are nearly barren. The places where bison wander and feed, on the other hand, stay lush and abundant with life. Prevent buffalo from migrating, Geremia tells me, and you remove the landscape’s ability to renew itself.
Preventing bison from migrating is part of his job, though. In 1995, the state of Montana sued Yellowstone National Park, arguing that the wandering buffalo were a business handicap. Livestock interest groups and local ranchers asserted that in addition to competing with cattle for grass and causing property damage, the bison could transmit the brucellosis pathogen to their herds.
We still have a shot at preserving this animal’s wild nature. To really save them it’s people who will have to do the evolving: learning to live in concert, not conflict, with the bison. Chris Douglas
Five years later, a drawn-out court battle resulted in the Interagency Bison Management Plan, a collective that meets each November to set a culling target for the coming winter. The group includes the Montana Department of Livestock; Montana Fish, Wildlife & Parks; the National Park Service; the USDA Animal and Plant Inspection Service; the U.S. Forest Service; and three tribal entities. They manage an annual slaughter aimed at keeping the Yellowstone buffalo population between 3,000 and 4,200, just barely enough to maintain genetic diversity.
A young bison thrashes against the cold steel of a squeeze chute, bucking and tossing its head in a panic. It takes two National Park Service employees, wielding electrified cattle prods, several attempts to close the hydraulic-powered sides of the stall around the animal. The immobilized yearling’s eyes open wide as Geremia and his colleagues examine its teeth, draw a syringe full of blood to test for brucellosis, and stick a numbered tag to its woolly flank. After a few minutes, they release it to a holding pen, where it joins several other unlucky buffalo.
This is Stephens Creek Capture Facility, a complex of corrals nestled in a valley along Yellowstone’s northern border. The site handles wild bison like livestock: Most of them, including some that test negative for brucellosis, board trailers and head to slaughter. The IBMP considers this the best way to mitigate risk.
It was cattle that first infected bison and elk with brucellosis, almost a century ago, when they were free to graze within the park. By the mid-20th century, brucellosis was the most common zoonotic disease in the world, affecting an estimated 124,000 U.S. cattle herds.
The illness, which could sweep through large swaths of livestock, delivered a financial hit to ranchers. But the risk to humans dealt a larger blow: Transferred through unpasteurized milk, the illness didn’t cause spontaneous abortion in people—just joint pain, night sweats, and headaches. But it did spread widely: In 1947, there were 6,400 reported cases of brucellosis in humans. These spurred a nationwide effort to eradicate the disease, which meant culling entire herds if a single animal showed evidence of infection. The strategy eventually evolved to include a vaccine for cattle that, while only 65 percent effective, at least eliminated the need to kill whole stocks.
By all accounts these measures succeeded. Today, the number of affected cattle herds is in the single digits, and fewer than 100 human cases get diagnosed annually. But because culling every bison and elk in a national park was never an option, and because there’s no effective method for vaccinating wild animals, 50 percent of the bison herd still carries brucellosis. The greater Yellowstone area is the last reservoir of the disease in the country.
The handful of documented brucellosis transmissions to cattle in recent decades have been tied to elk. Yet there are no constraints on the movement of elk outside the park. Some argue that’s due to breeding habits. Bison congregate during calving, when the risk of transmission is highest, while elk tend to separate their newborns from other animals. Others, like wildlife biologist Bailey, argue that the issue of brucellosis is just a straw man for a cultural clash. “This politically successful tactic,” he writes in his book American Plains Bison: Rewilding an Icon, “has been used to avoid the embarrassing argument that public bison will compete with private livestock for public forage on public land.”
Zaluski doesn’t embrace the slaughter, but he’s also against relaxing the rules. “It’s like saying, ‘My dog never gets out of my yard, so I don’t need to keep this fence.’ In that regard, we’re victims of our own success.”
The consequences, Bailey explains, are a slow but steady domestication of the genome through disease management, and demonstrable changes to the way bison move throughout the park. Hunting and capture operations on Yellowstone’s western boundary over several generations might explain why fewer bison now head that way each year. Buffalo learn migration paths from the previous generation. “Mobility, which gave bison the opportunity to utilize a large diversity of habitats in response to seasons and weather,” is part of what defines their wildness, Bailey says. But when nearly all the animals that try to take a certain route die, that aspect of wild behavior dies with them.
At mile marker 10 on highway 89, near Gardiner, there’s a bend in the Yellowstone River. For 50 years, Hank Rate, an Iowa-born rancher with a Harvard degree and a U.S. Forest Service background, has lived here with his family and a few dozen head of cattle. He came to this place, which he calls “the Serengeti of the temperate zone,” to live among wild things. I have to interrupt our conversation to stand in amazement on his porch, watching two bald eagles fight over a fish.
Rate doesn’t mind being pressed up against the bison, and he’s never worried much about the threat of brucellosis. As he sees it, this is the buffalo’s land; he’s just living on it.
And in recent years, Rate’s actually watched tolerance for bison start to grow in Montana. In late 2024, Governor Steve Bullock designated a year-round buffalo buffer zone outside Yellowstone’s northern and western entrances, where the law says they can’t be picked off or hazed back into the park. The territory includes tracts of public land surrounding Rate’s home, and one by one his neighbors responded by moving their cattle herds away.
Rate recognizes that his inherent comfort with wildness doesn’t work for everyone. Two-thousand-pound animals capable of charging at nearly 40 miles per hour aren’t all that compatible with the highways and housing developments that accompany humanity’s relentless sprawl. But if allowing the Yellowstone bison to roam just a little farther means they hang on to the natural behaviors that make them so special, well, Rate figures that’s an OK compromise.
Alternatively, Geremia, the park biologist, believes the best way to really preserve this wild herd is to use them to start new ones in other places. “Then maybe my son will always be able to see them,” he tells me. He and his colleagues have been trying for years to establish a quarantine program at Stephens Creek. Ideally, an agreement with Montana’s Department of Livestock would allow wild bison that repeatedly test negative for brucellosis to be relocated in the state and around the West, on enormous acreages far from cattle operations, where they can thrive and migrate freely. But progress on all fronts is slow.
Millions pilgrimage to Yellowstone every year to see the bison, their restoration touted as one of the great conservation success stories of the last century. But evolution marches on, and the next generation of visitors may find a herd that’s been intrinsically, irrevocably altered. The people who have dedicated their lives to the buffalo—studying them, conserving them, and, yes, helping to ship them to slaughter—are hopeful we won’t let it get that far.
Because we have Yellowstone, we still have a shot at preserving this animal’s wild nature. To really save them, it’s people who will have to do the evolving: learning to live in concert, not conflict, with the bison. “I hope we can do it,” Geremia says. “I think there are ways, where there’s enough land. There are other places where bison can be bison.” For now, at least, safe in the national park, the last living symbol of America’s Wild West abides.
