The iPhone is probably the world’s most used keyboard and there’s a simple secret hack that will speed up your typing with just a little tweak.As an iPhone user for over 15 years (yuck I feel old), I only encountered this keyboard hack recently and it has made me a far more efficient typer on my iPhone 15 Pro Max. Before I would type the modifier (123) key to get to numbers and symbols, press the key I need, and then tap the button again or the space bar to go back to letters — but not anymore.Here’s how to speed up your…

Scientists have developed a non-invasive brain stimulation method, Patterned Low-Intensity Low-Frequency Ultrasound (LILFUS), which can precisely modulate brain function and induce lasting changes. This breakthrough overcomes the limitations of traditional stimulation methods and shows potential for treating neurological disorders, improving motor skills, and possibly aiding in rehabilitation therapies. The research opens new avenues for using ultrasound in brain therapy, with implications for treating a wide range of…

Are you someone who finds it difficult to focus on one task for a lengthy period? If yes, then you are not the only one. As we are permanently connected to the internet, we are constantly bombarded with notifications from multiple sources such as social media, emails, ad notifications, chats, and much more. Therefore, it just takes a quick glance to get distracted and this delays our urgent and important tasks. Getting distracted is quite easy, however, gaining your focus and attention back to the task is the most…

 Tech giants are racing to ward off a carbon time bomb caused by the massive data centers they're building around the world.A technique pioneered by Google is gaining currency as more power-hungry artificial intelligence comes online: Using software to hunt for clean electricity in parts of the world with excess sun and wind on the grid, then ramping up data center operations there. Doing so could cut carbon and costs. There's an urgent need to figure out how to run data centers in ways that maximize renewable energy…

Recent research utilizing the SETI Ellipsoid method with TESS observations has advanced the search for extraterrestrial intelligence by enhancing the detection of potential signals from advanced civilizations. Leveraging continuous sky surveys and precise distance measurements from Gaia, the study improves our ability to monitor for technosignatures, setting a foundation for expanded future searches and representing a significant leap forward in SETI research efforts.Researchers demonstrate that the SETI Ellipsoid method,…

Almost half of all people in the world today speak an Indo-European language, one whose origins go back thousands of years to a single mother tongue. Languages as different as English, Russian, Hindustani, Latin and Sanskrit can all be traced back to this ancestral language.Over the last couple of hundred years, linguists have figured out a lot about that first Indo-European language, including many of the words it used and some of the grammatical rules that governed it. Along the way, they’ve come up with theories about…

Researchers have demonstrated the effectiveness of optical coherence tomography angiography in monitoring intermediate uveitis, a significant cause of global blindness. This new method links retinal blood flow with inflammation severity, offering a promising tool for predicting disease progression and identifying high-risk patients. Credit: SciTechDaily.comA new study introduces a novel approach to predicting the course of uveitis through retinal blood flow analysis, potentially transforming patient monitoring and…

A new study reveals an efficient method for extracting uranium ions from seawater using a specially designed electrode material. This approach offers a sustainable alternative to traditional uranium mining, potentially turning the oceans into vast sources of nuclear fuel.Most of the Earth’s surface is covered by oceans, which are teeming with a wide variety of life. Interestingly, these vast bodies of water also contain a dilute distribution of uranium ions. Extracting these ions could potentially offer a renewable source…

Researchers at MIT have that uses liquid metal to allow for extremely fast prints. The process can manufacture large aluminum components in minutes, whereas many pre-existing techniques would take hours to finish the same build. The technology has already been used to create table legs, chair frames and related furniture parts.It’s called liquid metal printing (LMP) and involves directing molten aluminum along a predefined path into a bed of tiny glass beads. These beads quickly harden into a 3D structure. Researchers…
