I changed 10 settings on my Fire TV to instantly improve the user experience
Why is my Fire TV running so slow?
That’s a complex question to answer. It could be the age of your device. Older hardware might struggle to load the latest apps and services. But it could also be a combination of outdated software, too many background processes, and accumulated temporary files. All these things can make your Fire TV or Fire TV Stick lag. Fortunately, the tips above address most of these problems.
Are there any other Fire TV features I can disable?
Amazon’s Fire TV has a surprising amount of “features” running in the background — many of which you might never use.
These processes eat up system resources and can slow things down. Turning off the ones you don’t need can speed up performance and tighten your privacy a bit. For instance, hold down the Home button on your remote to open the quick menu. Go to Settings > Applications > Prime Photos and toggle off Allow guest connections and Access Prime Photos (if you don’t use Prime Photos).
Also: Slow Fire TV? This 30-second fix made my system run like new again
While still under Applications, select Appstore and disable Automatic Updates (you can update apps manually later). Also in Appstore, you can optionally turn off In-app Purchases. Then select GameCircle (if you don’t game on your Fire TV) and toggle off Share your GameCircle Nickname and Whispersync for Games.
Each item you disable frees up a little extra memory and CPU overhead, which adds up over time — especially on older devices with limited RAM.
How often should I restart my Fire TV?
If you leave your Fire TV device powered on for long stretches at a time, a weekly restart is a good rule of thumb.
Will clearing cache or uninstalling apps delete my data?
Clearing cache will remove temporary files, not your logins or saved preferences. Uninstalling apps does remove any data specific to that app, but most streaming services store your watch history and preferences in the cloud, so you won’t lose purchases or profiles. You will need to log back into an app if you choose to delete it from your Fire TV or Fire TV Stick.
Do I really need to disable data monitoring and autoplay?
Disabling data monitoring and autoplay doesn’t affect your ability to watch shows or use apps — it just stops your Fire TV from constantly tracking data usage or playing auto-preview videos, which reduces background load.
When should I consider a factory reset?
As I mentioned above, a factory reset is a last resort. If you’ve been using your Fire TV for years and it’s still unbearably slow after trying every other tip, it’s worth a shot. It erases everything you’ve installed and customized and gives you a fresh start.
Also: Your car’s USB port is seriously underutilized: 5 features you’re not taking advantage of
All these tweaks, or even just a combination of some of them, will help you reclaim the speed you once enjoyed on your Fire TV. Let me know which in the comments worked for you and if there are others I missed and should consider trying.

“We’ve Never Reached This Level Before”: German Scientists Smash Nuclear Fusion Record in Leap Toward Infinite Clean Energy
IN A NUTSHELL - 🌟 The Wendelstein 7-X stellarator in Germany has set a new record in nuclear fusion performance, pushing the boundaries of clean energy.
- 🔬 Stellarators are proving more effective than tokamaks in maintaining stable plasma, crucial for long-duration fusion reactions.
- 🚀 Achieving a high triple product metric brings the world closer to a self-sustaining fusion reaction, with energy output exceeding input.
- 🤝 International collaboration has been key to these advancements, highlighting the global effort to develop sustainable fusion power.
In the pursuit of sustainable energy, nuclear fusion stands out as a beacon of hope, offering the potential for near-limitless power. Recent breakthroughs at the Wendelstein 7-X stellarator in Germany are pushing the boundaries of what we know about fusion energy. By mimicking the reactions that power the sun, scientists are making strides toward harnessing this energy source on Earth. These advancements mark significant progress in the realm of clean energy, setting new benchmarks for reactor performance and providing a glimpse into a future where fusion energy could become a reality.
The Promise of Nuclear Fusion
Nuclear fusion is often referred to as the holy grail of energy production. By fusing isotopes of hydrogen at incredibly high temperatures, fusion promises a clean, abundant, and safe energy source. Unlike nuclear fission, which splits atoms and produces radioactive waste, fusion has the potential to be a virtually limitless energy source with minimal environmental impact. The process involves creating a superheated plasma where atoms collide and fuse, releasing vast amounts of energy. However, the challenge lies in recreating the conditions found in stars, where such reactions naturally occur, within the confines of a terrestrial reactor.
While current reactor designs consume more energy than they produce, the recent experiments at the Wendelstein 7-X stellarator represent a significant leap forward. By achieving new records in fusion performance, these experiments demonstrate the viability of fusion as a feasible energy source. The promise of nuclear fusion is not just in its capacity to meet our growing energy needs but also in its ability to do so sustainably.

Stellarators vs. Tokamaks: A Comparative Look
Among the various reactor designs, stellarators and tokamaks are the most prominent. Stellarators like the Wendelstein 7-X use powerful external magnets to control the high-energy plasma within a ring-shaped vacuum chamber, maintaining stability and high pressure. This design contrasts with tokamaks, which rely on a current passing through the plasma to generate the magnetic field. The external magnets of stellarators are more effective at stabilizing the plasma, which is crucial for long-duration fusion reactions.
The recent success of the W7-X stellarator in surpassing the performance of decommissioned tokamaks such as JT60U in Japan and JET in the UK highlights its potential. The ability to sustain plasma for longer periods is a significant milestone, bringing us closer to the goal of a commercially viable fusion reactor. As research progresses, the choice between these two designs will play a critical role in the future of fusion energy.

Breaking New Records at Wendelstein 7-X
The Wendelstein 7-X stellarator has recently achieved a new record high in the triple product, a key metric for assessing fusion reactions. The triple product combines particle density, temperature, and energy confinement time, all of which are essential for a self-sustaining reaction. Achieving a high triple product is crucial because it indicates a more efficient reaction, bringing us closer to the Lawson criterion, where the energy produced exceeds the energy consumed.
One of the innovative techniques employed in the recent experiments was the use of a new fuel pellet injector. This device allowed for continuous refueling and pulsed heating, maintaining the plasma at the required temperature. The precise coordination between microwave pulses and pellet injection extended the duration of stable plasma, leading to an energy turnover of 1.8 gigajoules over six minutes. This achievement not only surpasses previous records but also underscores the potential of stellarators in advancing fusion technology.

Researchers from around the world have contributed to these breakthroughs, pooling resources and expertise to overcome the complex challenges of nuclear fusion. The latest achievements represent a significant step forward in validating the stellarator concept, made possible through outstanding teamwork and innovation.
As the world grapples with the challenges of climate change and energy scarcity, nuclear fusion offers a promising solution. While there is still much work to be done, the progress made at Wendelstein 7-X provides hope for a future where fusion energy could contribute significantly to global energy needs. The continued success of these experiments will depend on sustained international cooperation and investment in fusion research.
The breakthroughs at the Wendelstein 7-X stellarator mark an exciting time in the field of nuclear fusion. With each new record, we move closer to realizing the promise of fusion energy as a sustainable power source. As researchers continue to push the boundaries of what is possible, one must wonder: How soon will we see fusion power plants becoming a part of our everyday energy landscape?

Antarctic sea ice extremes disrupt global climate systems
Antarctic sea ice used to advance and retreat with seasonal regularity, but the rhythm has faltered. Scientists counted three record‑low summer ice seasons between 2017 and 2023, a run without precedent in four decades of satellite observations.
Dr. Edward Doddridge of the Institute for Marine and Antarctic Studies, University of Tasmania, has described the wider fallout of Antarctic sea ice loss in the journal PNAS Nexus.
“Antarctic sea ice appears to be changing; in the last decade, we have observed both record highs and record lows in Antarctic sea ice coverage. This article addresses the impacts of extreme lows in Antarctic summer sea ice coverage,” wrote Dr. Doddridge.
Sea ice loss impacts global climate
Sea ice is bright, and its high albedo bounces much of the Sun’s energy back to space. When dark ocean replaces that mirror, extra heat soaks in and lingers beneath the surface, nudging global temperatures upward.
The frozen cover also braces the coastline. Pack ice and the more stationary land‑fast variety absorb the punch of storm waves that would otherwise flex and crack vulnerable ice shelves, slowing the feed of inland glaciers into the sea.
How fast sea ice is shrinking
Dr. Doddridge’s team combined satellite records, Argo float profiles, and high‑resolution climate models.
The researchers showed that a single summer loss of 100,000 square miles of ice correlates with roughly six extra tabular icebergs that year, a figure the oceanographer calls “strikingly linear for a system famous for surprises.”
“With Antarctic sea ice providing climate and ecosystem services on regional and planetary scales, sustained and long‑term observations to accurately predict and potentially mitigate the impacts of climate change on this region should be a global scientific priority,” said Dr. Doddridge.
Model runs also revealed heat anomalies that persisted for three to four summers after the 2016‑17 plunge. That lingering warmth slows winter refreezing and suggests thresholds beyond which recovery is not quick or guaranteed.
Melting ice triggers ocean heating
Open water absorbs more solar energy, stratifying the upper ocean. Sensors show warming and freshening down to 1,300 feet after recent low‑ice summers, altering the formation of Antarctic Intermediate Water that helps lock away excess atmospheric heat and carbon.
Less sea ice also means fewer brine‑rich plumes sinking to ventilate the ocean interior. If that overturning slows, climate sensitivity could climb as the deep Pacific takes up less anthropogenic heat.
For many species, sea ice is both dining room and nursery. Larval krill feed on sea‑ice algae and hide from predators in its under‑surface; years with scant winter ice yield poor recruitment the following spring.
Emperor penguins suffered near‑total breeding failure in parts of the Bellingshausen Sea when the 2022 ice broke up before chicks had grown waterproof feathers.
Seals that haul out to molt face a similar squeeze as large floes fragment into smaller rafts with little room to rest or escape orcas.
Sea ice loss reshapes the food chain
Recent satellite and float data confirm that changes in ice extent are linked to shifts in phytoplankton bloom timing and intensity.
These microscopic plants form the foundation of the Antarctic food web, supporting everything from krill to whales, but the bloom response to ice loss is inconsistent across regions.
Some areas saw higher chlorophyll-a levels, signaling stronger blooms, especially near the coast where ice retreat was early and meltwater brought nutrients.
In other regions, despite longer open water seasons, blooms were weaker – likely due to deeper mixed layers or cloudier skies that reduced light for growth.
More than 4 million square kilometers of sea ice may support under-ice blooms, according to BGC‑Argo float measurements. These hidden blooms affect not only the carbon cycle but also cloud formation, altering how the region cools or warms the atmosphere.
Shipping, tourism, and fishing
The wave‑exposed coastlines calve more icebergs, rerouting shipping lanes and occasionally blocking access to research bases.
Tourism operators, less constrained by thick pack ice, have already logged more high‑latitude port calls during low‑ice summers, widening the footprint of black‑carbon emissions and invasive species risk.
Commercial krill fisheries may also chase pole‑ward stocks, complicating conservation plans around the Antarctic Peninsula.
Meanwhile, national programs are rethinking resupply windows as land‑fast ice, once a sturdy seasonal highway, thins and breaks weeks earlier than it did in the 1990s.
What happens if ice keeps shrinking
Dr. Doddridge and colleagues list circumpolar ice‑thickness monitoring as the single biggest data gap. Without it, models cannot pin down when volume, not just area, might cross a tipping point.
Public interest is already reacting; online searches for “Antarctic sea ice” hit a record peak in July 2023, a pulse researchers link to rising climate anxiety.
Better forecasts could temper fear with facts, but only if satellites, floats, and shore stations keep streaming year‑round measurements.
For now, the Southern Ocean’s frozen skin appears to be sliding toward a leaner state. Whether that new normal stabilizes or spirals depends on how fast the world reins in greenhouse‑gas emissions, a decision that will be felt from Hobart laboratories to emperor penguin rookeries.
The study is published in the journal PNAS Nexus.

Cough medicine turned brain protector? Ambroxol may slow Parkinson’s dementia
Dementia poses a major health challenge with no safe, affordable treatments to slow its progression.
Researchers at Lawson Research Institute (Lawson), the research arm of St. Joseph’s Health Care London, are investigating whether Ambroxol — a cough medicine used safely for decades in Europe — can slow dementia in people with Parkinson’s disease.
Published on June 30 in the prestigious JAMA Neurology, this 12-month clinical trial involving 55 participants with Parkinson’s disease dementia (PDD) monitored memory, psychiatric symptoms and GFAP, a blood marker linked to brain damage. Parkinson’s disease dementia causes memory loss, confusion, hallucinations and mood changes. About half of those diagnosed with Parkinson’s develop dementia within 10 years, profoundly affecting patients, families and the health care system.
Led by Cognitive Neurologist Dr. Stephen Pasternak, the study gave one group daily Ambroxol while the other group received a placebo. “Our goal was to change the course of Parkinson’s dementia,” says Pasternak. “This early trial offers hope and provides a strong foundation for larger studies.”
Key findings from the clinical trial include:
- Ambroxol was safe, well-tolerated and reached therapeutic levels in the brain
- Psychiatric symptoms worsened in the placebo group but remained stable in those taking Ambroxol.
- Participants with high-risk GBA1 gene variants showed improved cognitive performance on Ambroxol
- A marker of brain cell damage (GFAP) increased in the placebo group but stayed stable with Ambroxol, suggesting potential brain protection.
Although Ambroxol is approved in Europe for treating respiratory conditions and has a long-standing safety record — including use at high doses and during pregnancy — it is not approved for any use in Canada or the U.S.
“Current therapies for Parkinson’s disease and dementia address symptoms but do not stop the underlying disease,” explains Pasternak. “These findings suggest Ambroxol may protect brain function, especially in those genetically at risk. It offers a promising new treatment avenue where few currently exist.”
Ambroxol supports a key enzyme called glucocerebrosidase (GCase), which is produced by the GBA1 gene. In people with Parkinson’s disease, GCase levels are often low. When this enzyme doesn’t work properly, waste builds up in brain cells, leading to damage. Pasternak learned about Ambroxol during a fellowship at The Hospital for Sick Children (SickKids) in Toronto, where it was identified as a treatment for Gaucher disease — a rare genetic disorder in children caused by a deficiency of GCase.
He is now applying that research to explore whether boosting GCase with Ambroxol could help protect the brain in Parkinson’s-related diseases. “This research is vital because Parkinson’s dementia profoundly affects patients and families,” says Pasternak. “If a drug like Ambroxol can help, it could offer real hope and improve lives.”
Funded by the Weston Foundation, this study is an important step toward developing new treatments for Parkinson’s disease and other cognitive disorders, including dementia with Lewy bodies. Pasternak and his team plan to start a follow-up clinical trial focused specifically on cognition later this year.

The ski resort Olympians flock to each summer
According to Ellen Guidera Purcell, Henry’s wife and a key figure in Portillo’s day-to-day operations, the early days mostly involved the Purcells inviting their famous friends here for ski parties. “The parties were an omen of the future,” Guidera said. “Because Portillo has continued not only as a place for beautiful skiing but also as a place for good times with family and friends, a place of happy dinners, parties, bar dancing and making memories.”
Carolina Mendoza, a retired business owner, first visited Portillo in the mid-1970s as a teenager growing up in Venezuela. She’s returned nearly every year since, only missing a Portillo season during the pandemic or while living in Europe. For Mendoza, whose mother is Chilean, there’s a magic to this little mountain hamlet. “There’s such a sense of community here,” she said. ‘It almost makes you feel like you’re with family.”
But Portillo has also become synonymous with serious skiing. Known for its challenging alpine terrain, it hosted the FIS Alpine World Ski Championships in 1966, which established its reputation as a hardcore winter sports destination. Today, both the convivial atmosphere and the hair-raising slopes remain critical to Portillo’s cult-favoured status. Every year from June to September, when the northern hemisphere is in the throes of summer, snow-chasers from the US, Canada, Europe and Latin America head here to enjoy an endless winter. Many, like Mendoza, are repeat visitors. Others are world-class athletes in training for big-ticket events like the Olympics.
