Recent research demonstrates that brain organoids can indeed “learn” and perform tasks, thanks to AI-driven training techniques inspired by neuroscience and machine learning. AI technologies are essential here, as they decode complex neural data from the organoids, allowing scientists to observe how they adjust their cellular networks in response to stimuli. These AI algorithms also control the feedback signals, creating a biofeedback loop that allows the organoids to adapt and even demonstrate short-term memory (Bai et al. 2024).

One technique central to AI-integrated organoid computing is reservoir computing, a model traditionally used in silicon-based computing. In an open-loop setup, AI algorithms interact with organoids as they serve as the “reservoir,” for processing input signals and dynamically adjusting their responses. By interpreting these responses, researchers can classify, predict, and understand how organoids adapt to specific inputs, suggesting the potential for simple computational processing within a biological substrate (Kagan et al. 2023; Aaser et al. n.d.).

As people age, their memory and thinking skills naturally decline. Approximately 15% of older adults experience mild cognitive impairment, a major risk factor for dementia and other forms of dementia such as Alzheimer’s disease.

Since cognitive decline and dementia are growing public health concerns, scientists are working to better understand the risk factors and find ways to reduce them. One emerging area of research suggests that oral health may play a role in brain health.

Now, a new study suggests that the bacteria living in the mouth may influence cognitive function as people age, with some harmful bacteria possibly contributing to the development of dementia and Alzheimer’s disease.

Wireless communications technology has transformed the world, but the devices, which are quickly growing in number, require a consistent and ample source of power. Dong et al. developed a transparent device that harvests energy from two sources — radio waves and the sun — to power a wide range of wireless devices.

The breakthrough represents a significant step forward in optimizing energy conversion, since previous systems typically focused on harvesting either radio frequency or solar power, but not both. For example, coupling the energy harvester device with a solar cell increases the solar cell’s maximum power output by 13.11%. Furthermore, the device demonstrates an optical transparency of over 80 percent, allowing it to be invisibly integrated into many next-generation wireless technologies as both an energy harvester and a light transmitter.

Device may make smart windows and the Internet of Things more energetically sustainable.

WASHINGTON — As the demand for digital security grows, researchers have developed a new optical system that uses holograms to encode information, creating a level of encryption that traditional methods cannot penetrate. This advance could pave the way for more secure communication channels, helping to protect sensitive data.

“From rapidly evolving digital currencies to governance, healthcare, communications and social networks, the demand for robust protection systems to combat digital fraud continues to grow,” said research team leader Stelios Tzortzakis from the Institute of Electronic Structure and Laser, Foundation for Research and Technology Hellas and the University of Crete, both in Greece.

Optica is the leading society in optics and photonics. Quality information and inspiring interactions through publications, meetings, and membership.

Simulation Metaphysics extends beyond the conventional Simulation Theory, framing reality not merely as an arbitrary digital construct but as an ontological stratification. In this self-simulating, cybernetic manifold, the fundamental fabric of existence is computational, governed by algorithmic processes that generate physical laws and emergent minds. Under such a novel paradigm, the universe is conceived as an experiential matrix, an evolutionary substrate where the evolution of consciousness unfolds through nested layers of intelligence, progressively refining its self-awareness.

“There are numerous challenges involved in developing a membrane that could ultimately be used as lightsail. It needs to withstand heat, hold its shape under pressure, and ride stably along the axis of a laser beam,” said Dr. Harry Atwater, who is a Howard Hughes Professor of Applied Physics and Materials Science at Caltech and a co-author on the study. “But before we can begin building such a sail, we need to understand how the materials respond to radiation pressure from lasers. We wanted to know if we could determine the force being exerted on a membrane just by measuring its movements. It turns out we can.”

For the study, the researchers used real-life models to simulate the size of the lightsail, amount of laser power needed to propel the lightsail, and amount of pressure exerted on the lightsail to achieve the desired speed. After creating their own miniature lightsail measuring 40 microns long, 40 microns wide, and 50 nanometers thick tethered to four strings, the team subjected it to laser light to measure the amount of radiation pressure the lightsail was experiencing. In the end, the team found the specific angle and amount of force required to push the lightsail forward. Through this, they successfully established groundwork for potentially constructing larger lightsails in the future.

Astronomers have also calculated a predicted impact zone that stretches from South America across the Atlantic Ocean to sub-Saharan Africa.

The asteroid has the potential to cause significant damage, especially if it lands in a densely populated area like a major city due to it being the size of another space rock that hit Earth in 1908 with a blast equivalent to detonating 50 million tons of TNT.

Though estimates suggest a very small increase in the likelihood of impact, astronomer and professor of planetary sciences at the Massachusetts Institute of Technology (MIT) Richard P Binzel told DailyMail.com that it is nothing to worry about.
