Samsung reveals upcoming Galaxy Watch 8 features as it looks to improve your health

If you've been looking forward to the follow-up of the Galaxy Watch 7 then good news, as Samsung has revealed some of the new features coming to its next generation smartwatch.
Expected to be called the Samsung Galaxy Watch 8, the South Korean firm has published a post on its site detailing new features for 'the upcoming Galaxy Watch'.

The new features are geared towards improving 'sleep, heart health, fitness, and nutrition', so let's take a look at what the next Galaxy Watch will be packing.
Bedtime guidance
Samsung is improving its sleep tracking with new tools which will suggest the best time for you to go to bed based on your lifestyle. Your watch will also send your reminders to encourage to you follow the optimal routine for your bedtime.
Vascular Load
The new Galaxy Watch will measure your vascular load – the stress on your vascular system – while you're sleeping.
Being able to track the stress on your system while asleep with allow your Galaxy Watch to monitor heart health. When asleep, stress on your vascular system should decrease as your body rests, but if it doesn't it could be a sign you need to see a medical professional.
Samsung says this data can be analyzed alongside other metrics collected by the watch, to help create and maintain positive habits for a healthier lifestyle.
Running Coach
The new Running Coach feature sounds a little bit like Apple's Workout Buddy it announced for watchOS 26 at WWDC 2025 just last week.
Samsung's implementation, as the name suggests, is focused on running (where as Apple's version covers a wider set of workouts). It'll provide you with encouragement and motivation to get running and hit your goals,
To get started, you'll need to go for a 12 minute run wearing your Galaxy Watch. From that short session, the system will give you a running level between one and 10.
From there, Samsung says your watch will be able to deliver detailed training plans – such as training for a 5K, 10K, half marathon or full marathon. You'll be set a series of challenges to help hit your end goal, unlocking the next challenge on the competition of the previous one.
Running Coach will be able to provide your with intense, yet injury-preventive training, which could be a great feature of beginners.
Antioxidant Index
And finally, the last new feature in Samsung's teaser announcement is Antioxidant Index.
The new Galaxy Watch will be able to measure carotenoids (antioxidants found in green and orange vegetables and fruits) in your skin, using a light-activated BioActive sensor.
Antioxidants can help promote healthy aging, as they neutralize harmful 'free radicals' which can build up from specific lifestyle choices, such as smoking, drinking alcohol, sun bathing and a lack of sleep.
By being able to monitor your antioxidant levels, you'll be able to make changes to your lifestyle to improve or maintain your index reading.
Will my current Galaxy Watch get the new features?
Looking at the small print of Samsung's post, it all depends on which Galaxy Watch you own. If you have the high-end Galaxy Watch Ultra it looks like you'll be treated to all the new features, while Galaxy Watch 7 users will get access to the Running Coach.
You'll need the 'later released Galaxy Watch Series', or the Galaxy Watch Ultra, if you want to take advantage of the Vascular Load and Antioxidant Index features.
For existing Watch owners, supported new features will arrive via the One UI 8 Watch software update.
When will the Galaxy Watch 8 launch?
Reports currently suggest the Galaxy Watch 8 will be revealed alongside the Galaxy Z Fold 7 and Galaxy Z Flip 7, with rumors pointing towards a possible July launch event.
This would make sense, as the Z Fold 6, Flip 6 and Galaxy Watch 7 were launching on July 10, 2024, and we regularly see manufacturers repeat annual launch cycles.
Samsung has already been teasing the Galaxy Z Fold 7, and with the Galaxy Watch 8 teasers now appearing, all signs point to an imminent launch.

Breach Blocker

"Think of it as a weather forecast for cyber threats. We don't just tell you it's raining hackers, we tell you where the lightning will strike next," says Rahul Sasi, Co-Founder and CEO, CloudSEK Opinions expressed by Entrepreneur contributors are their own. You're reading Entrepreneur India, an international franchise of Entrepreneur Media. When it comes to cybersecurity threats, Rahul Sasi believes in being one step ahead, always. "We like to think of ourselves as a digital immune system for enterprises. Instead of reacting to cyberattacks after the damage is done, we predict where the first punch will land and help you dodge it," says the co-founder and CEO of CloudSEK. Founded in 2015 by Sasi, a cybersecurity researcher turned entrepreneur—CloudSEK was built on the ethos of prevention over cure. The company has since evolved into a trusted cybersecurity partner for over 250 enterprises, including Fortune 500 companies and digital-first unicorns across banking, healthcare, and tech. "While most tools detect attacks after the fact, we identify Indicators of Attack (IOAs), signals from the reconnaissance phase so customers can act before the breach happens." He adds, "Think of it as a weather forecast for cyber threats. We don't just tell you it's raining hackers, we tell you where the lightning will strike next." This proactive approach has earned CloudSEK a 4.8-star rating on Gartner Peer Insights across nearly 200 reviews, and recognition as the number one threat intelligence provider in APAC. "We've been recognised as a Customer First Vendor—proof that we're solving real problems, not just ticking compliance boxes," adds Sasi. With USD 40 million in total funding and a presence in five countries, CloudSEK is now doubling down on global expansion, particularly in the U.S., India, and UAE. The recent Series A2 and B1 rounds brought in USD 19 million, which will be used to further refine its AI models and deepen platform integration. "In cybersecurity, the moment you stand still, you're already behind," says Sasi. To stay ahead in a rapidly evolving landscape, CloudSEK has embraced a culture of relentless innovation. "We treat innovation like a Formula 1 pit crew—constantly tuning, upgrading, and pushing the limits," he says. The company is leveraging generative AI, crowdsourced threat intelligence, and real-time analytics to reduce response times and enhance threat visibility. CloudSEK's R&D and threat research teams work closely together to anticipate threat patterns and shape new detection models. "We're not just reacting to trends, we're setting them," Sasi adds. Despite strong tech and traction, Sasi admits the hardest challenge isn't technological, it's behavioural. "Getting organisations to shift from reactive to proactive security. Most teams still wait for a breach to happen before they act. It's like using GPS after you're already lost," he says. To change this mindset, CloudSEK builds intelligence frameworks that guide CISOs to ask the right questions first. "If we can help a company move from 'prevent' to 'predict,' they're not just more secure, they're ahead of the curve." On the business front, CloudSEK is inching closer to profitability. The company has grown 3x in the last two years and currently operates on an 81% gross margin, with positive cash flow expected in the next quarter. "We're built on a recurring revenue model. Think of it like a snowball rolling downhill—our base is expanding, and the platform is becoming stickier, so growth becomes more predictable and more profitable," Sasi notes. While headquartered in Singapore, CloudSEK's operations span India, the U.S., UK, and Brazil. With over 60 per cent of its new revenue coming from international markets, the U.S. has emerged as the fastest-growing region.

Does BYD or Tesla stock offer the best value?

Tesla (NASDAQ:TSLA) and BYD (OTC:BYDD.F) are the two titans of the global electric vehicle (EV) market, but their investment cases diverge sharply when you dig into the numbers and outlook. Here's how they stack up for investors looking ahead. Tesla's forward price-to-earnings (P/E) ratios remain stratospheric by any standard. The company is expected to trade at 168.8 times earnings in 2025, falling to 111.4 times in 2026 and 85.7 times in 2027. Even by its own five-year history, these multiples are elevated, and they are more than 10 times the consumer discretionary sector median. BYD, by contrast, looks far more modest. Its forward P/E is 18.4 times for 2025 and 14.2 times for 2026. That's just a fraction of Tesla's and much closer to sector norms. This huge valuation gap reflects the market's belief in Tesla's future growth, but also means any disappointment could hit the shares hard. Tesla's price-to-sales ratio for 2025 is a lofty 10.4 times, while BYD's is just 0.65 times. In other words, investors are paying a huge premium for each dollar of Tesla's sales, while BYD trades closer to traditional automaker multiples. BYD's lower multiple reflects its mass-market positioning and focus on affordability, while Tesla's premium signals expectations for high-margin growth and disruptive new business lines. Tesla boasts a market cap over $1trn, with $37bn in cash and $13bn in debt. This gives it a strong net cash position and plenty of firepower for R&D and expansion. BYD, with a market cap around $147bn, holds $21bn in cash and $5.7bn in debt. Still solid, but on a smaller scale. Tesla's financial muscle gives it flexibility, but BYD's balance sheet is also robust and supports its rapid global expansion. The real battleground is not just EVs, but autonomous driving and robotics. Tesla's valuation is highly detached from automotive peers because investors are betting it will dominate self-driving technology and unlock new business models like robotaxis and AI-powered logistics. Its Dojo supercomputer and Full Self-Driving (FSD) efforts are central to this thesis, though regulatory hurdles remain. BYD is not standing still. Its latest models integrate advanced driver-assist systems, LiDAR, and rapid-charging battery tech. This has already made headlines. However, its approach is more incremental, focusing on affordability, scale, and steady technological improvements. Coupled with the fact that it's Chinese, it hasn't been afforded the same attention by investors. BYD trades at far lower valuation multiples and has recently overtaken Tesla in global EV sales, especially in China and Europe. Meanwhile, Tesla commands a huge premium based on its potential to lead in autonomy and AI-driven transport. However, the execution risk is huge. For value-focused investors, BYD is the obvious choice, but clearly the market favours Tesla and Elon Musk's ambitions.

Alcohol linked to increased risk of pancreatic cancer: Study

Alcoholic beverages, particularly beer and spirits, may increase the risk of developing pancreatic cancer, according to a new study led by the UN World Health Organization. The research, which pooled data from nearly 2.5 million people across Asia, Australia, Europe and North America, revealed a 'modest but significant' link between alcohol consumption and pancreatic cancer risk, regardless of sex or smoking status. 'Alcohol consumption is a known carcinogen, but until now, the evidence linking it specifically to pancreatic cancer has been considered inconclusive,' said Pietro Ferrari, senior author of the study and head of the nutrition and metabolism branch at the World Health Organization International Agency for Research on Cancer. The study revealed that each additional 10 grams of alcohol consumed per day was associated with a three percent increase in pancreatic cancer risk. Additionally, women consuming 15-30 grams of alcohol daily, which equates to about one to two drinks, had a 12 percent higher risk. Men drinking 30-60 grams daily had a 15 percent increased risk, increasing to 36 percent for those consuming more than 60 grams. The study confirmed alcohol as an 'independent risk factor,' even after accounting for smoking. Ferrari emphasized that 'alcohol is often consumed in combination with tobacco,' but the elevated risk persists among non-smokers. Pancreatic cancer, a disease that impacts digestive enzyme production and blood sugar regulation, remains one of the deadliest cancers due to late-stage diagnoses. Although it ranks 12th in global cancer incidence, it accounts for 5 percent of all cancer-related deaths, according to the WHO. Copyright 2025 Nexstar Media, Inc. All rights reserved.
