Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has been out of reach.
kiwi (KEE-wee) - n., any of a small genus (Apteryx) of flightless New Zealand birds with rudimentary wings and a long slender bill; (informal, often capitalized) a New Zealander; (military) a member of an air force that doesn't fly; the egg-sized, edible berry of the Chinese gooseberry, with fuzzy brownish skin and slightly tart green flesh; a green-yellow color, like that of kiwi fruit flesh.

Okay, back to solid Polynesian—for Maori is very much a Polynesian language. [Sidebar: New Zealand was the last significant territory to be settled in the Polynesian Expansion, over 300 years after Easter Island and Hawaii.] Bird first: there are five species of kiwi, all about the size of a chicken and nocturnal and shy, thus the rather dark pic. While the Maori name has possible cognates in other Polynesian languages, including a couple that are birds native to islands Maori ancestors had come from, the general consensus is the name is onomatopoetic of the male kiwi's call. The kiwi fruits (several species of genus Actinidia, esp. A. chinensis var. deliciosa) on the other hand, is not native, but introduced from central China in the early 20th century and cultivated for export. The rebranding from Chinese gooseberry, based on both being brown, furry, and round, happened in 1959 to make them more export-friendly, and has been so successful that the most common name in Chinese has become the transliteration qíyìguǒ (奇異果, literally exotic/strange fruit).

The organic light-emitting diode (OLED) technology behind flexible cell phones, curved monitors, and televisions could one day be used to make on-skin sensors that show changes in temperature, blood flow, and pressure in real time.
There are hundreds of cell types in the human body, each with a specific role spelled out in their DNA. In theory, all it takes for cells to behave in desired ways—for example, getting them to produce a therapeutic molecule or assemble into a tissue graft—is the right DNA sequence. The problem is figuring out what DNA sequence codes for which behavior.
Major river deltas are sinking faster than sea-level rise, study shows
Jan. 14th, 2026 11:00 amA study published in Nature shows that many of the world's major river deltas are sinking faster than sea levels are rising, potentially affecting hundreds of millions of people in these regions.
Polyamines are small molecules naturally present in all cells and are critical in guiding cellular decisions, whereas an alteration in the abundance of these metabolites is invariably observed in pathological scenarios such as cancer or aging. Despite decades of research, the mechanisms through which polyamines control cellular decisions have remained obscure.
Artificial intelligence promises to accelerate scientific discovery and open new frontiers of inquiry. But new research from James Evans (Faculty Co-Director of Novel Intelligence; Max Palevsky Professor of Sociology & Data Science; and Director of the Knowledge Lab) and colleagues reveals how AI tools are expanding individual scientists' capabilities but narrowing the collective scope of science.
What happens when fire ignites in space? 'A ball of flame'
Jan. 14th, 2026 10:20 amWhen fire breaks out in the low-gravity, high-stakes conditions inside spacecraft or space stations, it behaves very differently than back here on Earth.
Ozone that protects us from the sun's harmful UV rays, when in an indoor space, reacts with oils present on skin, wall paint, or even cooking oil to produce chemicals that negatively impact cardiovascular health.
From bolts to blue jets, lightning comes in many strange forms
Jan. 14th, 2026 10:03 amLightning has captured people's fascination for millennia. It's embedded in mythology, religion and popular culture. Think of Thor in Norse mythology or Indra in Hinduism.
Cilia are micrometer-sized biological structures that occur frequently in nature. Their characteristic high-frequency, three-dimensional beating motions (5–40 Hz) play indispensable roles inside the body.
Foams are everywhere: soap suds, shaving cream, whipped toppings and food emulsions like mayonnaise. For decades, scientists believed that foams behave like glass, their microscopic components trapped in static, disordered configurations.
Homo habilis: The oldest and most complete skeleton discovered to date
Jan. 14th, 2026 09:50 amAn international research team has unveiled a significant discovery in human paleontology: an exceptionally well-preserved Homo habilis skeleton dating back more than 2 million years.
At TU Wien, researchers have discovered a state in a quantum material that had previously been considered impossible. The definition of topological states should be generalized.
Scientists built a robot to help explain how a tropical bat spots insects perched on leaves using echolocation, a highly sophisticated behavior that requires precise, split-second decision making on the part of the hunting bat.
Type Ia supernova delayed-detonation model supported by SN 2024gy observations
Jan. 14th, 2026 09:38 amA research team from the Yunnan Observatories of the Chinese Academy of Sciences (CAS), in collaboration with domestic and international partners, has carried out observational studies on SN 2024gy—a high-velocity Type Ia supernova (SN Ia)—using the Lijiang 2.4-meter telescope.
Two simple modifications cool Kenyan homes and keep mosquitoes out
Jan. 14th, 2026 09:30 amResearchers in Kenya have identified two low-cost solutions that tackle the twin challenges of rising temperatures and malaria transmission.
How 'smart' nanoparticles can deliver targeted gene therapy in osteoarthritis
Jan. 14th, 2026 09:30 amOsteoarthritis is a highly prevalent joint disease that leads to cartilage breakdown, pain and disability, yet there are still no FDA-approved treatments that can slow or reverse its progression. RNA-based therapies hold great promise because they can silence the molecular signals that drive cartilage degeneration. However, for these treatments to work, they must reach the damaged regions, called lesions, within the cartilage.
Marine researchers have been wowed by the size of a centuries-old black coral found in Fiordland.
