Optics & Photonics News - Ice Loss Narrows Spectrum of Ocean Light

1 week ago | optica-opn.org | Meeri Kim

The extent of sea ice that forms, expands and melts in the ocean is a key indicator of climate change. In recent years, ice cover has decreased dramatically, with predictions suggesting an ice-free Arctic Ocean in summer within the next few decades. The consequences of this steep decline are wide-ranging, such as less sunlight reflected back into space and disruption of ocean currents.
Optics & Photonics News - Detecting Nanoplastics in Bodily Fluids

3 weeks ago | optica-opn.org | Meeri Kim

Microplastics—as well as the smaller nanoplastics—are everywhere, including in our food, drinking water and even our bodies. These tiny pieces of plastic are not biodegradable, so they accumulate and persist in the environment. Many microplastics originate from the breakdown of larger plastics, such as plastic bags and bottles and clothing made with synthetic textiles.
Optics & Photonics News - Lattice Strain Boosts Solar Cells

1 month ago | optica-opn.org | Meeri Kim

Perovskite solar cells represent the fastest-developing photovoltaic technology to date, with a power-conversion efficiency (PCE) that has skyrocketed from 3.8% to 26.7% in the last 15 years. To further boost PCE, tandem architectures have been created that combine a wide-bandgap perovskite top cell with a narrow-bandgap bottom cell. However, light-induced phase segregation—a common occurrence in wide-bandgap perovskite formulations—limits their efficiency and stability.

2 hours agoIf you think the backlash is bad now, what happens when Optimus comes out? A few hours before Tesla reported some bad quarterly sales results, Elon Musk took to X to make a bold prediction about his next plan: “The rate of improvement is indeed rapid,” Musk wrote while sharing a post from an admirer …
How to keep your memory sharp as you age

How to keep your memory sharp as you age (washingtonpost.com) How to keep your memory sharp as you age By Meeri Kim 2025033118003300 Consumer Reports has no financial relationship with any advertisers on this site. With age, our brains change just as much as our bodies do — even if the shift isn't always as noticeable. Brain volume decreases, for example, and neural connections may weaken.
Optics & Photonics News - Twistronics Could Advance Quantum Devices

1 month ago | optica-opn.org | Meeri Kim

The emerging field of twistronics explores physics and phenomena that arise from modifying the relative twist angle between successive layers in 2D materials. Atomically thin materials can be vertically and horizontally stacked to create nanostructures, often producing unexpected results.
Dormir ajuda a destravar ideias? Veja o que diz a ciência

1 month ago | estadao.com.br | Meeri Kim

Quando o inventor Thomas Edison enfrentava um bloqueio criativo, ele usava um truque para ajudar sua mente a se destravar. Ele se sentava em sua cadeira favorita segurando bolas de aço nas mãos e começava a cochilar. Assim que seus músculos relaxavam o suficiente, as bolas escorregavam de suas mãos e caíam em bandejas no chão. O barulho alto o despertava. Edison afirmava que frequentemente acordava desses cochilos com novas ideias para continuar seu trabalho.

Estas tres técnicas pueden ayudar a las personas que sufren dolor persistente, según las investigaciones La falta de sueño es consecuencia del dolor crónico. Las terapias psicológicas pueden ayudar con este problema. By Meeri KimEl dolor es la forma que tiene nuestro cuerpo de avisarnos que algo anda mal. Cuando es agudo, suele comenzar de repente, con una causa evidente (como una fractura) y una solución estándar.
Does sleeping on an idea work? Here’s what science says

He would sit in his favourite chair holding steel balls in his hands and begin to doze off. Once his muscles relaxed enough, the balls would slip from his hands into pans on the floor. The loud noise would jar him awake. Edison claimed that he would often wake up from these cat naps with new ideas to continue his work. Salvador Dalí had a similar technique using a heavy key and credited it as one of his secrets to mastering the art of painting.
