Even as human-caused climate change threatens the environment, nature continues to inspire our technological advancement.
“The solutions that are provided by nature have evolved for billions of years and tested repeatedly every day since the beginning of time,” University of Edinburgh researcher Evripidis Gkanias said.
Gkanias has a special interest in how nature can educate artificial intelligence.

“Human creativity might be fascinating, but it cannot reach nature’s robustness — and engineers know that,” he said.
From compasses mimicking insect eyes to forest firefighting robots that behave like vines, here is a selection of this year’s nature-based technology.
Some insects — such as ants and bees — navigate visually based on the intensity and polarization of sunlight, thus using the sun’s position as a reference point. Researchers replicated their eye structure to construct a compass capable of estimating the sun’s location in the sky, even on cloudy days.
Common compasses rely on Earth’s weak magnetic field to navigate, which is easily disturbed by noise from electronics.
A prototype of the light-detecting compass is “already working great,” said Gkanias, who led the study published in Communications Engineering.
“With the appropriate funding, this could easily be transformed into a more compact and lightweight product” freely available, he added.
With a little further tweaking, the insect compass could work on any planet where a big celestial light source is visible.
Fabric inspired by the silky threads of a spider web and capable of collecting drinking water from morning mist could soon play an important role in regions affected by water scarcity.
The artificial threads draw from the feather-legged spider, whose intricate “spindle-knots” allow large water droplets to move and collect on its web.
Once the material can be mass produced, the water harvested could reach a “considerable scale for real application,” said Zheng Yongmei (鄭?梅), a coauthor of the study published in Advanced Functional Materials.
Animals are not the only source of inspiration from nature.
Scientists have created an inflatable robot that “grows” in the direction of light or heat, in the same way vines creep up a wall or across a forest floor. The about 2m-long tubular robot can steer itself using fluid-filled pouches rather than costly electronics.
In time, the robots could find hot spots and deliver fire suppression agents, researchers at the University of California, Santa Barbara say.
“These robots are slow, but that is OK for fighting smoldering fires, such as peat fires, which can be a major source of carbon emissions,” coauthor Charles Xiao said.
Before the robots can climb the terrain, they need to be more heat-resistant and agile.
Scientists at the Unconventional Computing Laboratory at the University of the West of England in Bristol have found a way to use slimy kombucha mats — produced by yeast and bacteria during the fermenting of the popular tea-based drink — to create “kombucha electronics.”
The scientists printed electrical circuits onto dried mats that were capable of illuminating small LED lights.
Dry kombucha mats share properties of textiles or even leather, but they are sustainable and biodegradable, and can even be immersed in water for days without being destroyed, the authors said.
“Kombucha wearables could potentially incorporate sensors and electronics within the material itself, providing a seamless and unobtrusive integration of technology with the human body,” such as for heart monitors or step-trackers, lead author and laboratory director Andrew Adamatzky said.
The mats are lighter, cheaper and more flexible than plastic, but the authors caution that durability and mass production remain significant obstacles.
Pangolins resemble a cross between a pine cone and an anteater. The soft-bodied mammals, covered in reptilian scales, are known to curl up in a ball to protect themselves against predators.
Now, a tiny robot might adapt that same design for potentially lifesaving work, a study published in Nature Communications showed.
It is intended to roll through our digestive tracts before unfurling and delivering medicine or stopping internal bleeding in hard-to-reach parts of the human body.
Lead author Soon Ren Hao of the Max Planck Institute for Intelligent Systems was watching a YouTube video when he “stumbled across the animal and saw it was a good fit.”
Soon needed a soft material that would not cause harm inside the human body, with the advantages of a hard material that could, for example, conduct electricity. The Pangolin’s unique structure was perfect.
The tiny robots are still in their initial stages, but they could be made for as little as 10 euros (US$11.03) each.
“Looking to nature to solve these kinds of problems is natural,” Soon said. “Every single design part of an animal serves a particular function. It’s very elegant.”
UNPRECEDENTED PACE: Micron Technology has announced plans to expand manufacturing capabilities with the acquisition of a new chip plant in Miaoli Micron Technology Inc unveiled a newly acquired chip plant in Miaoli County yesterday, as the company expands capacity to meet growing demand for advanced DRAM chips, including high-bandwidth memory chips amid the artificial intelligence boom. The plant in Miaoli County’s Tongluo Township (銅鑼), which Micron acquired from Powerchip Semiconductor Manufacturing Corp (力積電) for US$1.8 billion, is expected to make a sizeable capacity contribution to the company from fiscal 2028, the company said in a statement. It would be an extended production site of Micron’s large-scale manufacturing hub in Taichung, the company said. As the global semiconductor industry is racing to reach US$1 trillion
A man walks past real-estate advertisements outside a house in Taipei yesterday. The central bank yesterday said it plans to establish an “Inflation-at-Risk” gauge as a supplementary tool for observing inflation, as policymakers express wish to communicate more effectively with the public when making inflation forecasts.
ABOVE LEGAL REQUIREMENT: The Ministry of Economic Affairs is prepared if LNG supply is disrupted, with more than the legal requirement of 11 days of inventory Taiwan has largely secured liquefied natural gas (LNG) supplies through May and arranged about half of June’s supply, Minister of Economic Affairs Kung Ming-hsin (龔明鑫) said yesterday. Since the Middle East conflict began on Feb. 28, Taiwan’s LNG inventories have remained more than 12 days, exceeding the legal requirement of 11 days, indicating no major supply concerns for domestic gas and electricity, Kung said at a meeting of the legislature’s Economics Committee in Taipei. The ministry aims to increase the figure to 14 days by the end of next year, he said. While one or two LNG or crude oil shipments for May
Taiwan’s food delivery market could undergo a major shift if Singapore-based Grab Holdings Ltd completes its planned acquisition of Delivery Hero SE’s Foodpanda business in Taiwan, industry experts said. Grab on Monday last week announced it would acquire Foodpanda’s Taiwan operations for US$600 million. The deal is expected to be finalized in the second half of this year, with Grab aiming to complete user migration to its platform by the first half of next year. A duopoly between Uber Eats and Foodpanda dominates Taiwan’s delivery market, a structure that has remained intact since the Fair Trade Commission (FTC) blocked Uber Technologies Inc’s
