Mica is Microsoft’s new transparency effect for Windows 11. It is similar to Acrylic but optimised for performance by only sampling from your wallpaper rather than the app below you.
Microsoft has been rolling out the new look to more and more native apps, and now Office Insiders and Beta users are reporting that the effect is also showing up in their apps.
It’s a cool concept; the blades cant get caught, or stuck, or broken. but, it’s pretty loud, there’s no audio in the demo videos. Still, i think a flying drone would be superior for exploring underground structurers and caves, til it hit a door or something anyways. Anyhow, i think the flight system should focus on some kind of a total silence ion drive.
It was three years ago that we first heard about the Cleo, a robust, donut-shaped prototype drone made by Cleo Robotics. Well, its successor is now commercially available, under the new (and apt) name of the Dronut X1.

Physicists have created a new ultra-thin two-layer material with quantum properties that normally require rare earth compounds. This material, which is relatively easy to make and does not contain rare earth metals, could provide a new platform for quantum computing and advance research into unconventional superconductivity and quantum criticality.
The researchers showed that by starting from seemingly common materials, a radically new quantum state of matter can appear. The discovery emerged from their efforts to create a quantum spin liquid which they could use to investigate emergent quantum phenomena such as gauge theory. This involves fabricating a single layer of atomically thin tantalum disulfide, but the process also creates islands that consist of two layers.
Are viruses alive or are they lifeless packages of protein and nucleic acid?

Countless scientists around the world study life, and yet they can’t really agree on what it is. Join New York Times columnist Carl Zimmer as he explores the boundaries of life, encountering viruses and other strange residents of the borderlands.
The National Institutes of Health has launched a program to study a rare type of cells, called “senescent” cells, that play both positive and negative roles in biological processes. The NIH Common Fund’s Cellular Senescence Network (SenNet) program will leverage recent advances in studying individual cells, or single-cell analysis, to comprehensively identify and characterize the differences in senescent cells across the body, across various states of human health, and across the lifespan. The rarity and diversity of these cells previously made them difficult to identify and study; therefore, a deeper understanding will help researchers develop therapies that encourage beneficial effects of senescent cells while suppressing their tissue-damaging effects.
“The number of senescent cells in a person’s body increases with age, which may reflect both an increase in the generation of these cells and a decreased ability of the aging immune system to regulate or eliminate these cells. This age-related accumulation of senescent cells leads to production of inflammatory molecules and corruption of healthy cells,” said Richard J. Hodes, M.D., director of the National Institute on Aging, part of NIH. “This can affect a person’s ability to withstand stress or illness, recuperate from injuries, and maintain normal brain function. The aim of NIH’s strengthened focus on this field of science is to one day conquer these and other challenges.”
Through the integrated use of sensors, closed-circuit television network, automatic licence plate readers and facial recognition software, all of which feed data into a central control room, the Safe City project helps authorities predict incidents and take preemptive action against crime or violence, said Dr Major Ahmed Al Shamsi, head of Safe City Project at Abu Dhabi Police.
“The project was launched three years ago and currently covers 85 per cent of the emirate’s infrastructure. It has helped reduce traffic incidents and fatalities, patrol areas more efficiently and take action to prevent untoward occurrences,” he told Gulf News on the sidelines of the Abu Dhabi Smart City Summit.
The two-day summit is seeing the attendance of 400 experts, with the focus on the technological advances and innovations that are improving the quality of life in the UAE capital. Organised by Abu Dhabi emirate’s municipalities sector regulator, the Department of Municipalities and Transport (DMT), the Summit has already seen the launch of driverless taxis on Yas Island, as well as the signing of other agreements with technology developers like Huawei, Bayanat and G42.
By combining two-dimensional materials, researchers create a macroscopic quantum entangled state emulating rare earth compounds.
Ammolite is an opal-like organic gemstone found primarily along the eastern slopes of the Rocky Mountains of North America. It is made of the fossilized shells of ammonites, which in turn are composed primarily of aragonite, the same mineral contained in nacre, with a microstructure inherited from the shell. It is one of few biogenic gemstones; others include amber and pearl.
The chemical composition of ammolite is variable, and aside from aragonite may include calcite, silica, pyrite, or other minerals. The shell itself may contain a number of trace elements, including: aluminium; barium; chromium; copper; iron; magnesium; manganese; strontium; titanium; and vanadium. Its crystallography is orthorhombic. Its hardness is 4.5–5.5, and its specific gravity is 2.60–2.85.
An iridescent opal-like play of color is shown in fine specimens, mostly in shades of green and red; all the spectral colors are possible, however. The iridescence is due to the microstructure of the aragonite: unlike most other gems, whose colors come from light absorption, the iridescent color of ammolite comes from interference with the light that rebounds from stacked layers of thin platelets that make up the aragonite.
