Overcoming the optical resolution limit
When measuring with light, the lateral extent of the structures that can be resolved by an optical imaging system is fundamentally diffraction limited. Overcoming this limitation is a topic of great interest in recent research, and several approaches.....»»

The Event Horizon Telescope, which took the first ever image of a black hole, has made the highest ever resolution observations taken from the Earth's surface......»»
Discovery of a hidden epigenetic clock in mitochondria reveals a "lifespan limit line"
Building on their work on epigenetics of aging and transposable elements, researchers Dr. Ádám Sturm and Dr. Tibor Vellai from Eötvös Loránd University have made another advance in understanding the molecular mechanisms of aging. Their latest st.....»»
Researchers propose inexpensive 2.2-kilometer telescope that could make exoplanet movies
Can a kilometer-scale telescope help conduct more efficient science, and specifically for the field of optical interferometry? This is what a study recently posted to the preprint server arXiv hopes to address......»»
Mapping the sex life of malaria parasites at single cell resolution reveals genetics underlying transmission
Malaria is caused by a eukaryotic microbe of the Plasmodium genus, and is responsible for more deaths than all other parasitic diseases combined. In order to transmit from the human host to the mosquito vector, the parasite has to differentiate into.....»»
Researcher explores how you can stretch your mind to grasp quantum entanglement
My new article, "Quantum Entanglement of Optical Photons: The First Experiment, 1964–67," is intended to convey the spirit of a small research project that reaches into uncharted territory. The article breaks with tradition, as it offers a first-pe.....»»
Single nucleosomes tracked in live cells during cell division using super-resolution microscopy
Individual cells divide through a process called mitosis, during which the cell's copied DNA is separated between two resulting daughter cells. Despite recent advances in cell biology, the mechanism by which DNA condenses during mitosis is still poor.....»»
Swappable optics could be the perfect accessory for an iPhone Air
Suggestions that Apple plans to launch an iPhone 17 Slim or iPhone 17 Air are gaining ground, with most reports now pointing to a compromise device. One big compromise we might see is for Apple to limit the model to a single camera – but there m.....»»
Researchers demonstrate metasurfaces that control thermal radiation in unprecedented ways
Researchers with the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have experimentally demonstrated that metasurfaces (two-dimensional materials structured at the nanoscale) can precisely control the optical properties of t.....»»
After months of mulling, NASA will decide on Starliner return this weekend
"The agency flight readiness review is where any formal dissents are presented and reconciled." Enlarge / A high-resolution commercial Earth-imaging satellite owned by Maxar captured this view of the International Space Station o.....»»
Improving the accuracy of global cropland mapping
To address the needs of the agricultural monitoring community, IIASA scientists fused two of the latest high-quality, high-resolution, remotely sensed cropland products to produce an improved cropland map for early warning and food security assessmen.....»»
World"s first micromachine twists 2D materials at will
Just a few years ago, researchers discovered that changing the angle between two layers of graphene, an atom-thick sheet of carbon, also changed the material's electronic and optical properties. They then learned that a "twist" of 1.1 degrees—dubbe.....»»
Repurposing pencil lead as an optical material using plasma
Optical materials are essential in many modern applications, but controlling the way a material reflects light on its surface is costly and difficult. Now, in a recent study, researchers from Japan found a simple and low-cost way of tuning the reflec.....»»
Advanced orbital angular momentum mode switching in multimode fiber utilizing an optical neural network chip
The rapid development of technologies such as the internet, mobile communications, and artificial intelligence has dramatically increased the demand for high-capacity communication systems. Among various solutions, mode-division multiplexing (MDM) ha.....»»
Quality control: Neatly arranging crystal growth to make fine thin films
Table salt and refined sugar look white to our eyes, but that is only because their individual colorless crystals scatter visible light. This feature of crystals is not always desirable when it comes to materials for optical and electrical devices, h.....»»
New view of North Star reveals spotted surface
Researchers using Georgia State University's Center for High Angular Resolution Astronomy (CHARA) Array have identified new details about the size and appearance of the North Star, also known as Polaris. The new research is published in The Astrophys.....»»
Researchers develop nanoparticle array implantation for sensitive and reusable detection
Shanghai Jiao Tong University (SJTU) researchers have developed a highly sensitive and reusable surface-enhanced Raman spectroscopy (SERS) microfluidics system that has achieved a detection limit lower than 10 ppt (parts per trillion) of harmful subs.....»»
New Windows 11 build removes ancient, arbitrary 32GB size limit for FAT32 disks
But the Windows NT-era disk formatting UI hasn't been fixed yet. Enlarge / If you've formatted a disk in Windows in the last 30 years, you may have come across this dialog box. (credit: Andrew Cunningham) As we wait for.....»»
Transforming satellite imagery: Innovative fusion method for precision agriculture
Remote sensing plays a vital role in monitoring agricultural landscapes, yet current satellite sensors often struggle with the trade-off between spatial and temporal resolution......»»
Rising mercury pollution in soil could be related to climate change, study suggests
In 2017, the Minamata Convention on Mercury went into effect, designed to help curb mercury emissions and limit exposure across the globe. However, a new study of mercury levels in soil suggests that the treaty's provisions might not be enough. A stu.....»»
