Researchers at the University of Copenhagen found that a signaling mechanism in the cells’ ‘antennae’ may help explain why some fetuses develop disease in both the heart and other organs. About two of every 100 babies worldwide are born with congenital heart disease, but the biological processes responsible for these conditions are not fully understood. [...]
Miniature carvings deepen the mystery of humanity’s early artists.
Giovanni Kanter goes to at least one art museum whenever he visits a new city. That’s on top of his regular exploration of galleries in New York, where the 25-year-old ICU nurse lives and studies. He typically discovers new artists and gallery openings through word of mouth, though he has recently started curating his social media feed to serve relevant content (he’s currently in what he terms a “surrealism phase”).
He was raised on visual art; he's the son of painter Marianne Gargour and nephew of mixed-media artist Heather Hutchison and painter-printmaker Mark Thomas Kanter. His “exposure-oriented education” featured childhood visits to galleries and shows in and around Dallas, where he grew up, and in France, where he spent time with his grandparents.
But Kanter is an exception. Many other young people have a less immersive artistic education, perhaps shaped by occasional school trips or family visits to museums. If they haven’t internalized an instinct for what Kanter calls “moving through the art and absorbing it,” the museum experience is central to how they learn about and understand art.

Albanese government’s approval of North West Shelf gas extension being challenged by the Australian Conservation Foundation and Friends of Australian Rock Art
The Albanese government’s decision to approve one of the world’s largest gas projects in Western Australia is being challenged in the federal court, setting up a significant test of how Australia’s environment law deals with the climate crisis.
The Australian Conservation Foundation (ACF) and Friends of Australian Rock Art (Fara) are this week running concurrent court challenges against the approval of the extension of Woodside’s major North West Shelf gas export project.

In a new review paper, Dr. Gregory Marcus from the University of California, San Francisco and colleagues analyzed decades of research on how caffeine -- most often consumed as coffee -- affects the heart and its risk factors.

Everyday when you see any sort of graphic in a GUI (graphical user interface), or in any printed media such as a billboard, poster, etc; they relate to different image file formats. Each format was created for specific purposes. While some are universal, others are less known about, and a few are difficult to interact […]
The post What are some of the common image file formats? appeared first on Low End Mac.
A white spot on iPad screen can appear as a bright patch that remains visible while browsing, watching videos or using apps. It may be small and easy to ignore at first, then become distracting whenever the screen shows a white, gray or lightly colored background.
The spot may come from a temporary software problem, but a fixed bright area is more commonly connected to the display hardware. Pressure inside the iPad, a damaged backlight layer, display separation or an impact can create uneven illumination that no setting can remove.
Before arranging a repair, a few simple checks can reveal whether the spot belongs to the image being displayed or to the physical screen itself.
A white spot on iPad screen is often described as a bright spot, pressure mark or backlight patch. On iPads with LCD displays, light passes through several internal layers before reaching the glass. When one of those layers becomes damaged, separated or compressed, light can concentrate in one area.
The mark may be more visible against pale backgrounds and almost disappear when the screen displays black or dark content. This is different from a dead pixel, which usually appears as a tiny fixed dot rather than a larger cloudy patch.
Pressure is one possible cause. Carrying an iPad in an overloaded bag, placing heavy objects on it or using a tight case can place stress on the display. A drop may also disturb the internal screen layers without cracking the front glass.
Battery swelling can create similar pressure from inside the device. If the screen is lifting from the frame, the iPad feels unusually warm or the body appears bent, stop using it and seek service. A swollen battery should not be pressed back into place or handled as an ordinary screen defect.
The problem can also appear after a display replacement involving a poorly fitted or lower-quality part. Apple notes that nongenuine displays may produce inconsistent brightness, color or touch behavior.
Begin by opening several different apps. Look at the spot over a white webpage, a gray Settings screen, a dark photo and a full-screen video. A hardware-related mark normally stays in the same physical location regardless of what appears underneath it.
Rotate the iPad. If the content changes orientation but the bright patch remains in the same part of the glass, the display is the likely cause.
Taking a screenshot provides another useful test. A physical screen defect will not normally become part of the screenshot file.
Top button + either volume button
Top button + Home button
Open the screenshot on another device or send it to a trusted computer. If the white spot does not appear there, the image generated by iPadOS is normal and the problem is probably inside the display assembly.
If the mark appears in the screenshot, it may belong to an app, image, accessibility setting or software effect rather than the panel.
A restart is worth trying because it clears temporary display and system behavior without affecting personal files. It is unlikely to repair physical backlight damage, but it can eliminate a short-lived graphical problem.
Press and hold the top button and either volume button > Drag the power slider > Wait approximately 30 seconds > Hold the top button until the Apple logo appears
Press and hold the top button > Drag the power slider > Wait approximately 30 seconds > Hold the top button until the Apple logo appears
After restarting, return to the same pale background and check the area again. A spot that remains fixed is unlikely to be caused by a temporary iPadOS issue.
Lowering brightness may make a bright patch less distracting, but it does not repair the underlying display. The same applies to Dark Mode, Night Shift and Reduce White Point. These settings can change how noticeable the mark becomes without removing it.
Settings > Display & Brightness > Brightness
Test the iPad at several brightness levels. A backlight-related spot may become easier to see as brightness increases. Photographing the screen against a plain background at medium and high brightness can also help document the defect before requesting service.
Avoid pressing or rubbing the affected area. Pressure may temporarily change the appearance, but it can damage the display further. Internet advice suggesting that users massage bright spots out of a panel should be ignored.
Remove any rigid case that appears unusually tight or has been damaged. A poorly fitted case can place uneven pressure around the frame, particularly if the iPad has been dropped while inside it.
A screen protector normally cannot create a true illuminated patch beneath the display. It can, however, produce bubbles, trapped moisture or reflective marks that resemble a screen defect. Examine the iPad with the display turned off. If the mark is visible on the surface even when the screen is black, the protector or glass may be involved.
Do not remove a properly installed protector solely as an experiment unless the mark clearly appears close to its surface. A bright patch visible only while the display is illuminated usually comes from deeper inside the screen.
A persistent white spot generally requires display service when it remains after restarting and does not appear in screenshots. There is no iPadOS setting that can realign a damaged diffuser, remove internal pressure or repair separated display layers.
Back up the iPad before service so photos, documents and app data remain protected.
Settings > your name > iCloud > iCloud Backup > Back Up Now
Apple can inspect the device and determine whether the defect qualifies for warranty coverage, AppleCare service or paid repair. Coverage depends on the device, purchase date, condition and whether the problem resulted from accidental damage.
Settings > General > AppleCare & Warranty
Apple or an Apple Authorized Service Provider may replace the display assembly or the iPad, depending on the model and available service process. The final repair estimate normally requires inspection.
A stable white spot that has not changed for months may remain only a visual annoyance. A spot that is expanding, accompanied by screen lifting or followed by unusual heat needs faster attention.
Stop using the device if the display separates from the enclosure, the iPad becomes visibly swollen or pressure marks spread across the panel. Do not puncture the device, force the display closed or continue charging it unattended.
For an ordinary fixed bright patch, the practical path is simpler: confirm it does not appear in screenshots, restart the iPad, remove any case applying pressure and arrange display service if the mark remains.
A white spot on iPad screen rarely affects the information stored on the device, but it can indicate physical damage that software cannot correct. A brief check can rule out the easy causes. After that, repair is usually more effective than repeatedly changing display settings and hoping the light disappears.
