  • Apple iPhone 17 And iPhone 17 Pro Design Changes Revealed In Wide-Ranging Leak

    Apple iPhone 17 And iPhone 17 Pro Design Changes Revealed In Wide-Ranging Leak

    Updated July 19 with more color details for more upcoming iPhones.

    With less than two months until the release of the next iPhones (read full details of the exact date expected here), there’s a lot that has been reported by now. But now it looks like the colors of the iPhones are coming into focus. The latest data has information about the regular iPhone 17, too.

    A new report from Macworld claims that the colors have been confirmed in what it describes as the “definitive lineup thanks to our sources.”

    ForbesApple iPhone 17 Release Date: New Leak Reveals Latest Key Data

    Why are colors so important? Well, for a start they’re a way to show everyone that you have the new model if you pick this year’s hero color. And in a less shallow reason, it’s a way to express yourself, especially if you’re one of those brave (foolhardy) people who don’t clad their expensive phone in a case.

    As the report says, recently a reputable leaker, Sonny Dickson, has said that the iPhone 17 Pro range will include two colors not in the iPhone 16 Pro range: dark blue and copper.

    “ Independent sources who requested anonymity told Macworld that we can indeed expect these new colors for the iPhone 17 lineup. The same source independently verified the Desert Titanium color for the iPhone 16 Pro before last year’s launch,” the report says.

    Although the publication says that its list is definitive, it’s worth noting that there is still some uncertainty about the exact color list. Macworld says there are two colors which will be the same as the iPhone 16 Pro, black and white. Let me stop you there: Apple almost always tweaks its colors from generation to generations so don’t be surprised if even black and white turn out to be different this year, especially if rumors of different case materials prove to be true.

    But for sure, versions of black and white are likely to be present.

    A new report from leaker Majin Bu says that these four will be the iPhone 17 Pro range, disagreeing with Macworld which says there’ll be a gray option, too.

    It’s worth noting that four is the number of colors that Apple has stuck to for its Pro models for years. The only recent exception was the iPhone 13 Pro and Pro Max, when the initial September 2021 range of four colors had a handsome alpine green hue added six months later. And, to add, whatever colors the iPhone 17 Pro will have, the Pro Max will exactly mirror it.

    Majin Bu claims the copper will be “a bold new orange”. Pro shades are invariably muted, so this would be a big departure. Personally, I think copper is more likely.

    Even so, these four shades look like being the iPhone 17 Pro color range.

    So, how about the regular iPhone 17? Macworld claims six colors are coming — again, this is one more than is usual and the only time there have been six was also 2022 when the iPhone 13 series added a green version. Which means it’s possible that one of these colors will be missing in September, to be added later.

    The current range is one of the best in recent years, I’d say, with black and white supplemented by pink and the two standouts: teal and aquamarine.

    Macworld says white and black, will stay (which seems very likely) while the rest of the range will be steel gray, green, purple and light blue. How they will compare to the iPhone 16 shades in terms of vividness remains to be seen.

  • Israel and Syria agree ceasefire as Israel allows Syrian troops limited access to Sweida

    Israel and Syria agree ceasefire as Israel allows Syrian troops limited access to Sweida

    Israel and Syria have agreed to a ceasefire, the U.S. envoy to Turkey said on Friday, after days of bloodshed in the predominantly Druze area that has killed over 300 people.

    On Wednesday, Israel launched airstrikes in Damascus and hit government forces in the south, demanding they withdraw and saying that Israel aimed to protect Syrian Druze – part of a small but influential minority that also has members in Lebanon and Israel.

    “We call upon Druze, Bedouins, and Sunnis to put down their weapons and together with other minorities build a new and united Syrian identity,” Tom Barrack, the U.S. ambassador to Turkey, said in a post on X.

    Barrack said that Israel and Syria agreed to the ceasefire supported by Turkey, Jordan and neighbors.

    The Israeli embassy in Washington and Syrian consulate in Canada did not immediately respond to requests for comment.

    Syria’s Sweida province has been engulfed by nearly a week of violence triggered by clashes between Bedouin fighters and Druze factions.

    Earlier on Friday, an Israeli official said Israel agreed to allow Syrian forces limited access to the Sweida area of southern Syria for the next two days.

    The Syrian presidency said late on Friday that authorities would deploy a force in the south dedicated to ending the clashes, in coordination with political and security measures to restore stability and prevent the return of violence.

    Damascus earlier this week dispatched government troops to quell the fighting, but they were accused of carrying out widespread violations against the Druze and were hit by Israeli strikes before withdrawing under a truce agreed on Wednesday.

    Israel had repeatedly said it would not allow Syrian troops to deploy to the country’s south, but on Friday it said it would grant them a brief window to end renewed clashes there.

    “In light of the ongoing instability in southwest Syria, Israel has agreed to allow limited entry of the (Syrian) internal security forces into Sweida district for the next 48 hours,” the official, who declined to be named, told reporters.

    Describing Syria’s new rulers as barely disguised jihadists, Israel has vowed to shield the area’s Druze community from attack, encouraged by calls from Israel’s own Druze minority.

    It carried out more strikes on Sweida in the early hours of Friday.

    The U.S. intervened to help secure the earlier truce between government forces and Druze fighters, and the White House said on Thursday that it appeared to be holding.

    Syrian leader Ahmed al-Sharaa, who has worked to establish warmer ties with the U.S., accused Israel of trying to fracture Syria and promised to protect its Druze minority.

    Reuters reporters saw a convoy of units from Syria’s interior ministry stopped on a road in Daraa province, which lies directly east of Sweida. A security source told Reuters that forces were awaiting a final green light to enter Sweida.

    But thousands of Bedouin fighters were still streaming into Sweida on Friday, the Reuters reporters said, prompting fears among residents that violence would continue unabated.

    The Syrian Network for Human Rights said it had documented 321 deaths in fighting since Sunday, among them medical personnel, women and children. It said they included field executions by all sides.

    Syria’s minister for emergencies said more than 500 wounded had been treated and hundreds of families had been evacuated out of the city.

    ‘Nothing at all’

    Clashes continued in the north and west of Sweida province, according to residents and Ryan Marouf, the head of local news outlet Sweida24.

    Residents said they had little food and water, and that electricity had been cut to the city for several days.

    “For four days, there has been no electricity, no fuel, no food, no drink, nothing at all,” said Mudar, a 28-year-old resident of Sweida who asked to be identified only by his first name out of fear of reprisals.

    “The clashes haven’t stopped,” he said, adding that “we can’t get news easily because there’s barely internet or phone coverage.”

    The head of the U.N. human rights office urged Syria’s interim authorities to ensure accountability for what it said are credible reports of widespread rights violations during the fighting, including summary executions and kidnappings, the office said in a statement.

    At least 13 people were unlawfully killed in one recorded incident on Tuesday when affiliates of the interim authorities opened fire at a family gathering, the OHCHR said. Six men were summarily executed near their homes the same day.

    The UN refugee agency on Friday urged all sides to allow humanitarian access, which it said had been curtailed by the violence.

    Israel’s deep distrust of Syria’s new Islamist-led leadership appears to be at odds with the United States, which said it did not support the recent Israeli strikes on Syria.

    ‘King’ to star Shah Rukh Khan along with daughter Suhana

    Shah Rukh Khan, widely-known as the King of Bollywood, has met an accident while shooting for his new film.

    The Pathaan actor, while shooting an action-packed scene for upcoming movie King at Golden Tobacco Studio in Mumbai, suffered an injury.

    Khan has performed many action sequences in his previous movies but none of them has ever took a toll on his body and health.

    This is the first time he had met an injury for which he has been flown to the USA along with his team for instant medical care.

    According to reports, the 60-year-old Bollywood star has not suffered a serious injury, but it still does need medical attention and rest.

    “It’s not very serious, but Shah Rukh has suffered muscle injuries before, and this one needed attention. After a small surgery, doctors advised him to rest for a month”, a source told Bollywood Hungama.

    The filming of King has been put to halt and the next spell is expected to resume in September once the Kuch Kuch Hota Hai actor fully recovers.

    Sources said in a statement, “The next shooting schedule will now begin around September or October. Once SRK fully recovers, he’ll return to work with full energy.”

    Directed by Sujoy Ghosh, King will mark as the first collaboration between father and daughter duo, Shah Rukh Khan and Suhana.

  • Latest Leak Has Unwelcome News

    Latest Leak Has Unwelcome News

    Apple is thought to be releasing four iPhones this September (read here for the exact release date). Alongside the iPhone 17, iPhone 17 Pro and iPhone 17 Pro Max will be a super-thin model, presumed to be called iPhone 17 Air. But the thin profile has ramifications when it comes to how long the battery will last.

    Since the new phone is thought to be just 5.5mm thick from front to back (so, even thinner than the recently released Samsung Galaxy S25 Edge), there’s not much room for a big battery.

    ForbesApple iPhone 17 Release Date: New Leak Reveals Latest Key Data

    Squeezing stuff in to a svelte device like this will be tough — and may be why there’s only one rear camera expected on it as sensors and lenses take up space internally as well as outside.

    iPhone 17 Air: The Bad News

    A new post on Weibo from regular leaker Instant Digital, picked up by MacRumors, says that the battery capacity will be less than 3,000 mAh. When you compare that to reports that the iPhone 17 Pro Max (expected to be a record-breaking Pro iPhone for thickness and other features) will have a 5,000 mAh battery and you can see why people might be disappointed.

    After all, a thin, gorgeous design is desirable, but not if it conks out at lunchtime.

    This report corroborates a previous rumor that the battery will have a lower capacity than most iPhones of recent years.

    However, there’s good news as well.

    iPhone 17 Air: The Good News

    The leaker has some comfort: “Although the battery does not exceed 3000mAh, the whole power saving mode should be able to last for one day,” they say.

    The power saving mode seems to refer to the Adaptive Power Mode coming with iOS 26, something Bloomberg’s Mark Gurman has previously noted, and which should provide a windfall of extra battery life for all iPhone 17 models — and even some current iPhones.

    Note that Instant Digital is still only predicting “one day” of battery life. But, after all, nearly everyone charges their iPhone overnight, right?

  • NOBS Toothpaste Tablets: What Dentists Say About Its Main Ingredient

    NOBS Toothpaste Tablets: What Dentists Say About Its Main Ingredient

    The NOBS (No Bad Stuff) toothpaste tablets are going viral thanks to their main ingredient of nano-hydroxyapatite, a fluoride-free alternative. As health concerns around fluoride and its presence in public drinking water continue to swirl, nano-hydroxyapatite toothpastes are becoming increasingly popular. You’ve likely seen them on store shelves or in ads from companies like Boka and Davids, marketed as fluoride-free alternatives for your toothbrush that claim to whiten teeth, repair enamel and prevent cavities. 

    “As ingredient labels shift toward cleaner, fluoride-free formulas, one compound is taking center stage in modern oral care: nano-hydroxyapatite,” Dr. Pia Lieb, DDS, cosmetic dentist and clinical assistant professor emerita at NYU College of Dentistry, explains. According to dentists, if you’re considering replacing your fluoride toothpaste with a nano-hydroxyapatite alternative like the now-viral NOBS, you should know the following potential benefits and side effects. 

    What is nano-hydroxyapatite?

    “Nano-hydroxyapatite is a synthetic calcium phosphate compound that’s used in some oral care products, including toothpastes,” explains Dr. Ada Cooper, consumer advisor and spokesperson for the American Dental Association, says. “[It] has a structure that is similar to hydroxyapatite found in enamel, and nHAP gets incorporated into the tooth structure preferentially in demineralized areas.” 

    Nano-hydroxyapatite is also abbreviated as n-HA and n-HAp.

    Dr. Royce Lai of King Village Dental adds that this is technically a two-part question, since “hydroxyapatite has been around for decades and has been studied for at least 20 years.” Newer and less studied, nano-hydroxyapatite is a version of hydroxyapatite with small, rod-shaped particles. 

    “Hydroxyapatite is natural. It is a type of calcium that makes up bones and teeth,” says Lai. “Nano-hydroxyapatite relates to the particle size. These are between 20 and 80 nanometers and are much smaller than the hydroxyapatite tubules that are a part of your teeth.” 

    According to Dr. Daniela Eversgerd, a cosmetic dentist and the founder of Allure Dental, nano-hydroxyapatite was developed by NASA in the 1970s for astronauts dealing with bone and enamel loss during long periods of space travel. Since the early 1990s, it has been approved for oral care products in Japan. 

    Nano-hydroxyapatite toothpaste benefits

    “Nano-hydroxyapatite doesn’t just protect your teeth — it helps rebuild them,” says Dr. Catrise Austin, a cosmetic dentist, author of Gum Health Made Simple and host of the Let’s Talk Smiles podcast. She lists the following as potential nano-hydroxyapatite benefits:

    • Enamel remineralization
    • Tooth sensitivity relief
    • Reduced bacterial adhesion
    • Whitening and gloss enhancement

    “n-HA can actually fill microscopic cracks and help reverse or arrest early cavities,” adds dentist Dr. Sandip Sachar.

    Austin cites a 2019 study that found a 10% hydroxyapatite toothpaste is equivalent or non-inferior to fluoride toothpaste for preventing and remineralizing dental cavities (or caries) in children. 

    Health Tips

    When it comes to teeth sensitivity, Lai cites a 2014 study concluding that 15% nano-hydroxyapatite helped sensitive teeth. “The particle size could get into space and work better than larger particles in micro-hydroxyapatite or fluoride,” he explains. “The conclusion was that nano-hydroxyapatite could significantly reduce tooth sensitivity to hot and cold in two to four weeks of use.”

    Referencing an 18-month 2023 clinical trial finding that a 10% n-HAp toothpaste protected adult teeth from new cavities as well as a standard 1,450-ppm fluoride paste, Dr. Christopher Tolmie, DDS, MBA, of PDS Health, states, “By patching enamel and calming swollen gums, nano-hydroxyapatite may cut off a hidden spark of chronic inflammation linked to heart disease and diabetes.” 

    Since nano-hydroxyapatite toothpastes are fluoride free, Dr. Yenile Y. Pinto, DDS, functional and biomimetic dentist and founder of Deering Dental, adds, “It’s also been shown to reduce sensitivity and strengthen the enamel surface without the risk of fluorosis.” Fluorosis occurs when you get too much fluoride as a child, causing white or brown spots on the teeth. The CDC reports that fluorosis typically doesn’t affect tooth function and isn’t painful. 

    A 2020 systematic review of 32 studies concluded that “Nano-HA is a relatively novel material with outstanding physical, chemical, mechanical and biological properties that makes it suitable for multiple interventions. It outperformed most of the classic materials used in implantology and surgery, but it should be further investigated for bone engineering and caries prevention therapy.”

    A 2023 comprehensive review found that, while more long-term studies are needed to establish the safety of regular use, “Nanohydroxyapatite is a promising revolutionary material in the prevention of early carious lesion mainly due to a greater source of free calcium.”

    Ultimately, providing a 2021 review and 2022 scoping review, Cooper concludes, “Although there is some evidence that alternative ingredients, such as [nano] hydroxyapatite, prevent tooth decay by acting as a remineralizing or anti-cavity agent, the studies are preliminary. The only anti-cavity agent recognized by the Food and Drug Administration in its over-the-counter monograph is fluoride, a naturally occurring chemical.” 

    Cooper adds that all toothpastes with the ADA Seal of Acceptance contain fluoride. The administration specifically recommends brushing your teeth twice a day with fluoride toothpaste and regularly visiting your dentist. 

    Nano-hydroxyapatite toothpaste side effects

    “According to a [2021] narrative review from Odontology, the official journal of the Society of the Nippon Dental University, so far, there have been no reports of adverse dental or systemic effects of HAP-containing toothpastes because HAP has an excellent biocompatibility,” states Cooper. 

    According to Austin, the concern with nano-hydroxyapatite is that, because it’s made of nanoparticles, some worry about how much might get absorbed into the body if regularly swallowed. “The European Commission’s Scientific Committee raised concerns due to the lack of long-term safety data on ingestion, particularly in children,” she says. This has led to temporary nano-hydroxyapatite restrictions (not a full-on banning) in Europe. 

    The European Scientific Committee deems nHA safe in toothpaste up to 29.5% and up to 10% in mouthwash, per Tolmie. However, he states, “Regulators still bar it from breath-spray products to avoid lung exposure, so stick to pastes and rinses.”

    Key concerns around nano-hydroxyapatite, according to Lieb, are: 

    • Potential ingestion and systemic absorption, especially in nano form
    • Lack of long-term studies in humans on the cumulative effects
    • Unknown impact of inhalation from aerosol products (not toothpaste)

    In terms of systemic absorption, Sachar specifies, “Because nano-hydroxyapatite particles are similar in composition to bone mineral, there has been some theoretical concern that if absorbed systemically, they could potentially contribute to unwanted calcifications in soft tissues (like blood vessels or kidneys).” However, she states that this is speculative and not supported by any current clinical evidence.

    Is nano-hydroxyapatite toothpaste only effective at 10%?

    “Most clinical formulations of nHA range from 5%-15%, with 10% emerging as the benchmark concentration in several Japanese and European studies,” answers Lieb. “This concentration has demonstrated reliable enamel restoration while maintaining product stability and usability.”

    However, she states that newer formulations are experimenting with lower concentrations and enhanced delivery systems (such as encapsulation or synergistic minerals), which may improve efficacy at reduced levels. “The effectiveness isn’t just about percentage, it’s also about particle quality and how it’s delivered to the tooth surface,” she explains. 

    Tolmie adds, “Effective repair starts as low as 5% and plateaus around 10-15%. Several studies show that 5% n-HAp can mend enamel dings, divots and dents in the teeth, with benefits leveling off somewhere between 10% and 15%. One review even noted that 5% sometimes beats 10% because fewer particles clump, making them easier to slip into enamel defects; hence, most US brands sit comfortably in the 5-10% sweet spot.”

    Should people replace fluoride toothpaste with nano-hydroxyapatite?

    Eversgerd states that it all depends on each person’s oral health needs. “Fluoride remains the gold standard for cavity prevention, supported by decades of large-scale, randomized controlled trials,” she explains. “However, for patients seeking a fluoride alternative — whether due to sensitivity, allergies, personal preferences or a desire for a biomimetic approach — nano-hydroxyapatite provides a scientifically supported option.”

    According to the Academy of Biomimetic Dentistry, a biomimetic approach is one in which damaged teeth are restored using materials mimicking natural teeth in function, strength and appearance. 

    For high-risk patients, Eversgerd recommends fluoride, while she may recommend n-Ha to low-risk or fluoride-averse individuals.

    Austin seconds this, but adds that she also recommends fluoride toothpaste to children with poor brushing habits or communities with limited dental access. “nHA is a great option, but it’s not a one-size-fits-all replacement for fluoride — yet,” Austin says. 

    Lieb explains that nHA may also be a compelling alternative for patients with aesthetic concerns, such as whitening-induced sensitivity, and individuals in preventive care regimens post-restorative treatment.

    Pinto agrees that it depends on the person, stating, “For most of my patients, especially those with low to moderate cavity risk, nano-hydroxyapatite is an excellent option; gentler on the mouth, less drying and effective at rebuilding early damage. For people with high cavity risk, fluoride might still be the best choice, at least short term. For my high-risk patients, I often recommend a combo toothpaste that includes both ingredients when appropriate.” Ultimately, if a patient isn’t high risk and has health or safety concerns about fluoride, she thinks hydroxyapatite is a great option.

    When asked if there’s a reason people should choose n-HAp over other anti-cavity toothpastes, Tolmie answers, “No, as long as patients are brushing their teeth with an anti-cavity toothpaste. There are differences in the way an n-HAp toothpaste and a fluoride toothpaste work to prevent decay, and some n-HAp toothpastes may feel smoother on the teeth. But anti-cavity toothpastes as a whole accomplish the same task. Do I wash a car with tap water or bottled water? We know that both of them get the job done.”

    What’s most important, according to Tolmie, is that patients ensure they’re not swallowing toothpaste.

    What does the American Dental Association think? Cooper states that the ADA recommends brushing teeth twice daily for two minutes with fluoride toothpaste, as the naturally occurring mineral has been proven to remineralize weakened enamel and reverse early signs of tooth decay. 

    “Additionally, the fluoride you take in from drinking water and other beverages continues to provide a topical benefit because it becomes part of your saliva, constantly bathing the teeth and helping to rebuild weakened tooth enamel,” Cooper further explains. “The best scientific evidence has shown that adding fluoride to community water supplies is safe and effective. This is backed by decades of research and recognized by more than 100 health organizations.”

    Does nano-hydroxyapatite toothpaste work? 

    All of the dentists we consulted agree that nano-hydroxyapatite toothpaste works, but in the right context and with the right product. It’s also not a miracle cure and should not replace your entire oral care routine, dentist’s recommendations or regular appointments. Plus, Eversgerd adds that more long-term, large-scale trials are needed to fully validate whether it’s equal to fluoride in preventing cavities. 

    When asked if it’s effective, Austin says, “Yes — particularly for enamel remineralization and sensitivity. In my practice, I’ve seen patients who switched to nHA toothpaste experience noticeable improvements in comfort, plaque control and surface smoothness. But like any product, it works best when paired with consistent brushing, flossing and professional cleanings.”

    Pinto agrees and has also seen the results firsthand. “It helps remineralize enamel, soothe sensitivity and support a healthier oral microbiome, especially when paired with a good routine (good home hygiene, healthy diet, hydration and nasal breathing),” she explains, noting that it’s not a miracle cure, but does offer many benefits.

    On behalf of the ADA, Cooper echoes Eversgerd’s earlier statement: “The use of nano-hydroxyapatite (nHAP) in over-the-counter products is growing and some evidence shows that nHAP may contribute to remineralization, but the evidence is fairly new and often ambiguous, especially regarding clinical indications. ”

    Do experts recommend nano-hydroxyapatite toothpaste?

    All of the experts we consulted do recommend nano-hydroxyapatite toothpaste, but only for certain patients. After all, according to Austin, “Nearly half of US adults over 30 have some form of gum disease, and you can’t out-toothpaste a bad hygiene routine.” Brushing your teeth regularly, flossing and regularly visiting your dentist are still essential, no matter what toothpaste you use. 

    Though Lieb recommends nHA toothpaste for adult patients experiencing post-whitening sensitivity or early enamel erosion, low-caries risk individuals seeking natural alternatives and adults undergoing cosmetic dental work who want to protect their investment with gentle, remineralizing care, she doesn’t recommend nano-hydroxyapatite for children with deciduous dentition. 

    “In my professional opinion, fluoride remains the safest and most effective option for all patients under 14,” says Lieb. “Its protective effect during the development of permanent dentition is unmatched, and its caries-prevention record is well established.”

    Sachar states that she often recommends it for “patients seeking fluoride-free options, those with mild tooth sensitivity and for children at risk of swallowing fluoride toothpaste.” However, she advises that patients with moderate to high cavity risk not fully abandon fluoride. 

    Again, it’s important to note that the “ADA recommends that adults brush their teeth twice daily with fluoride toothpaste for at least two minutes each time, or as directed by a licensed dentist,” according to Cooper. This is because the proposed benefits of nHAP are fairly new and ambiguous.

    The bottom line 

    Though more research is needed, the dentists we consulted explained that nano-hydroxyapatite toothpaste can be an effective alternative to fluoride — but only in the right context. The ADA doesn’t recommend it. It’s also not a miracle cure or a replacement for brushing regularly, flossing and professional dental appointments. 

    If you’re considering nano-hydroxyapatite toothpaste, consult your dentist first before making the switch. They know your teeth best and will be able to help you find the best toothpaste for your smile.
