While many smoking rooms in U.S. airports have closed in recent years, they are still common in other airports around the world. These lounges can be ventilated, but how much does it actually help the dispersion of smoke?
In a groundbreaking discovery, astronomers have identified an exoplanet unlike any other in our known universe. Dubbed “Cotton Candy” due to its ethereal appearance, this celestial body has left scientists baffled and intrigued.
Located in the Kepler-47-star system, approximately 1,200 light-years away from Earth, Cotton Candy orbits a binary star—a pair of stars that orbit each other. Its most remarkable feature is its unusually low density, which has led astronomers to describe it as the fluffiest exoplanet ever detected.
Cotton Candy’s density is so low that it defies our current understanding of planetary formation. According to Dr. Elena Rodriguez, lead researcher at the Galactic Exoplanet Institute, “We cannot explain how this planet formed.” The prevailing theories about planet formation involve the accumulation of dust and gas in a protoplanetary disk, eventually coalescing into a solid body. However, Cotton Candy’s density challenges this model.
Advancements in nuclear physics suggest the possibility of discovering stable, superheavy elements.
Researchers have found an alternative way to produce atoms of the superheavy element livermorium. The new method opens up the possibility of creating another element that could be the heaviest in the world so far: number 120.
The search for new elements is driven by the goal of finding versions that are stable enough to exist beyond a fleeting moment. In nuclear physics, there is a concept known as the “island of stability”—a hypothetical region in the upper reaches of the periodic table where as-yet-undiscovered superheavy elements could potentially last longer than just a few seconds. Scientists are working to explore how far the stability of atomic nuclei can extend.
Researchers at Tampere University have created the world’s first soft touchpad capable of detecting the force, area, and location of contact without the need for electricity. This innovative device operates using pneumatic channels, making it suitable for environments like MRI machines and other settings where electronic devices are impractical. The technology could also be advantageous for applications in soft robotics and rehabilitation aids.
Researchers at Tampere University have developed the world’s first soft touchpad that is able to sense the force, area, and location of contact without electricity. That has traditionally required electronic sensors, but the newly developed touchpad does not need electricity as it uses pneumatic channels embedded in the device for detection.
Made entirely of soft silicone, the device contains 32 channels that adapt to touch, each only a few hundred micrometers wide. In addition to detecting the force, area, and location of touch, the device is precise enough to recognize handwritten letters on its surface and it can even distinguish multiple simultaneous touches.
Australia has served up a Secure Innovation Placemat [PDF].
The wide variance in the documents is by design: each Five Eyes nation chose its own approach, although the campaign is a coordinated effort that is billed as “consistent and consolidated advice reflecting both the globalized and interconnected tech startup ecosystem as well as the global nature of the security threats startups face.” And everybody uses placemats.
Whether this advice will break through the “move fast and break things” culture that many startups nurture is anyone’s guess. The Register has reported on security and resilience troubles in the early years at Uber and Lyft, GitLab, and at OpenAI.
Researchers have developed a new ultrafast laser platform that generates ultra-broadband ultraviolet (UV) frequency combs with an unprecedented one million comb lines, providing exceptional spectral resolution. The new approach, which also produces extremely accurate and stable frequencies, could enhance high-resolution atomic and molecular spectroscopy.
The conservation law is a fundamental tool that significantly aids our quest to understand the world, playing a crucial role across various scientific disciplines. Particularly in strong-field physics, these laws enhance our comprehension of atomic and molecular structures as well as the ultrafast dynamics of electrons.
Two systems exist in thermal equilibrium if no heat passes between them. Computers, which consume energy and give off heat as they process information, operate far from thermal equilibrium. Were they to stop consuming energy—say you let your laptop discharge completely—they would stop functioning.
Electrons spin even without an electric charge and this motion in condensed matter constitutes spin current, which is attracting a great deal of attention for next-generation technology such as memory devices. An Osaka Metropolitan University-led research group has been able to gain further insight into this important topic in the field of spintronics.
Quantum computers hold the promise to emulate complex materials, helping researchers better understand the physical properties that arise from interacting atoms and electrons. This may one day lead to the discovery or design of better semiconductors, insulators, or superconductors that could be used to make ever faster, more powerful, and more energy-efficient electronics.
