5:2 fasting diet's anti-inflammatory effects come down to two proteins

Gizmag news -

The most prevalent chronic liver condition worldwide is non-alcoholic fatty liver disease (NAFLD), a build-up of fat in the liver that isn’t caused by heavy alcohol use. Linked to genetics and overweight or obesity, if NAFLD is left untreated, it can progress into its most severe form, called NASH (non-alcoholic steatohepatitis), which is characterized by liver inflammation and scarring. NASH also increases the risk of liver failure and liver cancer.

'New' genetic Alzheimer's disease may impact 6.7 million Americans

Gizmag news -

An incredible new study has upended our understanding of genetic Alzheimer's disease, finding that nearly everyone carrying two copies of a culprit gene had distinct biological markers of the degenerative condition by the age of 65. This means the APOE4 gene may no longer merely a risk factor but the driver behind a new stand-alone genetic Alzheimer's disease type that could impact up to 10 million Americans and more than 200 million people worldwide.

I can't say I've seen anything like this "underwater mobility device" before. The idea is simple enough; you extend the Seabike's pole to the appropriate length, then strap it to your waist with a belt. Then you find the pedals with your feet, and start turning the crank, with the waist strap to push against.

Apple launches new iPads, apps and accessories aimed at media creators: Here's what you need to know

Digital Photography Review news -

Apple's newest iPad Pro models incorporate a novel OLED display.

Image: Apple

At its "Let Loose" event on Thursday, Apple announced new products, apps, and accessories aimed at content creators and multimedia users. Whether you're a photographer, videographer, or even a video editor, there's a lot that's new. Here's a rundown of today's announcements.

iPad Pro

The headline feature of the latest iPad Pro is its new OLED display, which promises to deliver deeper blacks and brighter whites for photo and video applications, resulting in improved contrast, better motion processing and improved HDR.

Apple says that standard OLED screens don't produce the levels of brightness required for its XDR display technology, so the iPad Pro's OLED screen employs a feature Apple calls "Tandem OLED," which uses two OLED panels and combines the light from both.

The result is a screen that produces 1000 nits of full-screen brightness, with up to 1600 nits of peak brightness for HDR. This matches the numbers for the previous 13" iPad Pro (which used a mini-LED panel) but significantly improves upon the previous 11" model, which maxed out at 600 nits.

Apple's newest iPad Pro models incorporate "Tandem OLED" displays that combine the light from two OLED panels to generate enough brightness for Apple's XDR display.

For the first time, the iPad Pro's screen includes a nano-texture glass option, which does a better job of maintaining image quality and contrast while reducing glare and which Apple says should provide a better experience for people using color-managed workflows or those who work in bright conditions with light and reflections.

The new iPad Pro is the first device to use Apple's newest M4 processor, skipping over the M3 generation entirely and seeing a big jump in processing power. Apple claims the M4 delivers up to 50% faster CPU performance than the previous M2-based iPad Pros and up to 4x the rendering performance of the M2.

"The new iPad Pro is the first device to use Apple's newest M4 processor, skipping over the M3 generation entirely"

The M4 also received an update to its Neural Engine, which is dedicated to AI processing. Apple claims it delivers faster performance than neural processing units in any PC and can support AI-based features in applications, citing the example of using AI in Final Cut Pro to isolate the subject from a 4K video clip at the tap of a button.

The iPad Pro receives a design makeover as well. To start, the front-facing camera has been moved from the short edge of the device to the long edge, making it much more usable in landscape view. Considering that Apple has often positioned the iPad as a possible laptop replacement, complete with detachable keyboards, this makes a lot of sense. In fact, it's surprising it took this long.

The new 11" iPad Pro is just 5.3mm (0.21") thick, compared to 5.9mm on the previous 11" model, and weighs in at 444g (0.98 lbs), 22g lighter than its predecessor.

The new iPad Pro models are even thinner than their predecessors.

The new 13" iPad Pro is even thinner at 5.1mm (0.20"), compared to 6.4mm for the previous 13" model, which represents an impressive 20% decrease in thickness. (Who says Apple isn't obsessed with making things thin?) It weighs 579g (1.28 lbs), compared to 682g on the previous model, a 15% drop.

Despite reduced weight and size, Apple says the new iPad Pros deliver the same level of battery performance as their predecessors thanks to the increased power efficiency of the M4 chip and that the new processor can deliver the same performance as the M2-based iPad Pros with just half the power.

Finally, the new models double the base-level storage to 256GB, with storage options up to 2TB. The 11" model starts at $999, and the 13" model starts at $1299.

Final Cut Pro 2 for iPad

Apple also announced Final Cut Pro 2 for iPad, the first major update since the application debuted a year ago. The new version adds external project support, allowing editors to create or open projects on an external storage device like an SSD. This makes it possible to start a project on an iPad and later bring it into Final Cut Pro on a Mac if desired.

Final Cut Pro 2 for iPad includes support for live multi-camera recording.

The other significant feature in Final Cut Pro 2 is Live Multicam, which allows users to connect and preview up to four iPhone or iPad cameras live for multi-camera recording and editing. When using Live Multicam, Final Cut Pro will automatically transfer and sync video from each connected device to simplify a multi-camera workflow.

As with the original version of Final Cut Pro for iPad, the new version has a subscription model that costs $5/month or $49/year.

Final Cut Camera

In addition to Final Cut Pro 2, Apple introduced a free app called Final Cut Camera, which can be used with the new Live Multicam feature in Final Cut Pro 2. Final Cut Camera includes monitoring tools like zebras and audio meters, and allows users to adjust settings like white balance, ISO and shutter speed, and supports manual focus.

The Final Cut Camera app provides more granular controls than Apple's built-in camera app.

Image: Apple

Final Cut Camera isn't limited to integration with Final Cut Pro. It can also be used as a standalone app for shooting video, providing much more granular control than Apple's built-in camera app and potentially creating some new competition for advanced third-party video recording apps like Blackmagic Camera or Filmic Pro.

iPad Air

For users who may not need or want all the features offered by the iPad Pro, Apple also unveiled new iPad Air models. Most noteworthy is the addition of a new 13" iPad Air. Apple says it added the larger model based on the fact that roughly half of iPad Pro users choose the 13" screen size.

The iPad Air now includes 11" and 13" models.

Image: Apple

The updated iPad Air models are built around Apple's M2 processor, which Apple claims results in 50% faster performance than the previous M1 model.

Like the iPad Pro, the iPad Air sees the front-facing camera move to the long edge of the device to better support camera use in landscape mode. Also, like the iPad Pro, base storage has doubled and now starts at 128GB with options up to 1TB.

The new iPad Air is compatible with accessories like Apple's Magic Keyboard and Apple Pencil. The 11" iPad Air starts at $599, while the 13" model starts at $799.

Accessories

Along with new iPads and apps, Apple updated one popular accessory, the Magic Keyboard, and introduced a second, the Apple Pencil Pro.

The new Magic Keyboard, which connects to an iPad using magnets, is thinner than previous models and adds a row of function keys. It also includes a larger trackpad with haptic feedback. The new Magic Keyboard for 11" iPads retails for $299, while the model for 13" iPads retails for $349.

The Apple Pencil Pro is an evolution of the existing Apple Pencil. Its party trick is that the pencil barrel becomes a control surface: squeeze it, and a sensor in the barrel with haptic feedback can be used to do things like open a tool palette. It also includes a gyroscope, so it's possible to rotate the pencil to reorient the direction of a shape or brush. The Apple Pencil Pro works with iPad Pro and iPad Air and retails for $129.

Apple says all the new products announced today can be ordered immediately, with availability beginning next week.

Google mid-priced Pixel 8a brings processor and feature boost to familiar cameras

Digital Photography Review news -

Image: Google

Google has announced the Pixel 8a, its latest mid-priced smartphone, bringing the sensors and lenses from the Pixel 7a but the more powerful processor and features from the Pixel 8 and 8 Pro. It also gets a brighter screen, now earning Google's 'Actua' branding.

Recent Videos

The main camera is a 64MP camera with an F1.89 lens with an 80° angle of view (approximately 26mm equivalent, in 35mm terms). This uses a Type 1/1.73 (7.4 x 5.5mm) sensor.

There's also a 13MP ultrawide with an F2.2 aperture and 120° angle of view (∼12.5mm equiv). The front camera remains a 13MP camera with F2.2 lens and 96.5° AoV (∼19mm equiv). Both these cameras use Type 1/3 (4.7 x 3.5mm) sensors.

19mm e F2.2 1.12μm Type 1/3
(4.7 x 3.4mm) 7.4x

While the cameras themselves remain unchanged, the 8a gets an upgraded screen, now offering a peak brightness of 2000 nits. This, and a wider color gamut, earn it the company's 'Actua' branding, previously only used on the top-end phones. It can refresh at up to 120Hz, to give a smooth, responsive look.

The panel is not exactly the same as that in the Pixel 8, though, with the company calling it a glass-OLED, rather than the plastic-OLED panel used in the 8.

Google says one of its core aims with the new phone was to deliver "the best camera in a smartphone under $500." Underpinning these hopes is the use of the same Tensor G3 processor used in the more expensive Pixel 8.

The Pixel 8a will be available in four colors, including Aloe (pictured), Obsidian (black), Bay (blue) and Porcelain (off-white).

Image: Google

The Pixel 8a includes features such as 'Best Take,' which takes a burst of images and then lets you choose the expression for each person in the image. It also includes Magic Editor, which uses generative AI to fill in the background, allowing you to select, resize and move subjects in the image, and Magic Eraser to remove distracting objects.

It also includes a "photo unblur" system that tried to up-res blurry parts of your images.

New to the Pixel 8a is Audio Magic Eraser, which analyses the audio in videos, splits it up into what it thinks are the different sound sources, and lets you selectively delete just the distracting audio elements.

It also includes the Guided Frame feature that gives audio cues for people with limited vision, which has been expanded to help take photos of pets, food and documents, as well as faces. As with all recent Google cameras it also utilizes the company's 'Real Tone' processing to more accurately render a wider range of skin tones.

The company promises a 15% increase in battery life over the 7a, and the 8a maintains the same IP67 weatherproofing rating as its predecessor. It's also essentially the same dimensions, at 152.1 x 72.7 x 8.9mm (6.0 x 2.9 x 0.4").

The Pixel 8a will be available starting from $499, in 128Gb or 256Gb varieties. Google promises security updates will be provided for seven years from launch.

The Hasselblad XCD 2.5/25 V has a snap-back focus ring, engaging manual focus and revealing a distance scale.

Image: Hasselblad

Hasselblad has announced the XCD 2.5/25V, a 25mm F2.5 lens for its X-system 44x33mm medium format cameras.

Recent Videos

The 2.5/25V ends up acting as a 20mm equivalent ultra-wide lens on the X1D, X2D and 907x cameras, making it the second-widest option in the lineup, behind the 21mm F4. As with all XCD lenses, it features an internal leaf shutter, in this case allowing flash sync all the way up to its maximum speed of 1/4000 sec.

Hasselblad suggests its use for "shooting at night or dusk and blue hour," and says it can be used for: "cityscapes, street photography, natural landscapes/astrophotography ... as well as low light indoor portraits and close-ups."

Image: Hasselblad

It shares the features of the company's V ("versatile") series of XCD lenses, including a snap-back manual focus ring that reveals a distance scale on the barrel. It also has a user-configurable control ring, that can be used to control settings such as aperture value or ISO.

The complex 13-element, 10-group design includes four aspherical elements and three extra-low dispersion glass elements. It features an internal focus design driven by a stepper motor to deliver what the company describes as "fast, accurate, and responsive focusing."

It can focus down to 25cm (9.8"), giving a maximum reproduction ratio of 1:5.8.

The 2.5/25 is 105mm long and 75mm in diameter (4.1 x 3.0") and accepts 72mm filters. It weighs 592g (20.9 oz).

The lens will cost $3699.

Press Release:

HASSELBLAD INTRODUCES THE XCD 2,5/25V, A WIDE ANGLE LENS FOR NIGHT PHOTOGRAPHY

The XCD 2,5/25V is the widest-angle lens in the Hasselblad XCD Versatile (V) series lenses. It has a 20mm full-frame equivalent focal length and a maximum aperture of f/2,5. With its expansive view and large aperture, the XCD 2,5/25V was designed for turning nocturnal cityscapes, starry skies, and indoor portraits into extraordinary captures.

Its wide-angle focal length encompasses a wealth of scenic elements, providing photographers with ample space and composition. The f/2,5 large aperture, coupled with its excellent optical performance, ensures rich highlights and shadows are captured within every frame, even at dusk or after dark.

The XCD 2,5/25V features an optical structure of thirteen elements in ten groups, including four aspherical elements and three ED elements, meeting the high-resolution requirements of 100-megapixel sensors. This ensures images are sharp and crisp from the centre to the edges while effectively suppressing chromatic dispersion.

The optical quality of the lens is also showcased by its robust close-up capabilities. With a 25cm minimum focusing distance and 1:5:8 magnification, its large aperture accentuates close ups, enhancing the expressiveness of subjects like gourmet dishes and flowers.

As part of the Hasselblad XCD V lens series, the design of the XCD 2,5/25V is known for integrating user-friendly functionality with elegance, in both its aesthetics and control. Enhancing the elegance is an engraved “V" insignia on the lens, with the "H" logo engraved on both the focus and control rings.

With a gentle push- pull of the focus ring, photographers can quickly switch between AF and MF modes. ‌In MF mode, intuitive scale marks on the lens keep focus distance and depth of field at a clear glance, enabling precise focus control. Functions such as aperture, shutter speed, ISO, and exposure compensation can be customised on the control ring, serving as an extension of the camera, allowing users to capture the perfect moment with ease.

The XCD 2,5/25V is equipped with a linear stepping motor and a smaller, lighter focusing lens group, providing a quick and responsive focusing experience when paired with Hasselblad X or V system cameras that support PDAF.

The lens adopts a large-diameter leaf shutter module with a shutter speed of up to 1/4000s. This enables both global shutter and flash synchronisation at all speeds.

The XCD 2,5/25V lens is priced at $3,699 USD / 4,199 EUR and is available to purchase online and at selected retail stores worldwide. For more information about the XCD 2,5/25V, visit www.hasselblad.com.
