Peacock Feathers Can Emit Laser Beams

It turns out peacock feathers can emit laser light when dyed multiple times, according to a paper published in the journal Scientific Reports. Per the authors, it's the first example of a biolaser cavity within the animal kingdom.

Bright iridescent colors in things like peacock feathers come from their structure. The scales of chitin (a polysaccharide common to insects) in butterfly wings, for example, are arranged like roof tiles. Essentially, they form a diffraction grating, except photonic crystals only produce certain colors, or wavelengths, of light, while a diffraction grating will produce the entire spectrum, much like a prism.

In the experiment, the researchers cut away any excess lengths of barbs and mounted the peacock feathers on an absorptive substrate. They then infused the feathers with common dyes by pipetting the dye solution directly onto them and letting them dry. The feathers were stained multiple times in some cases. Then they pumped the samples with pulses of light and measured any resulting emissions.

The team observed laser emissions in two distinct wavelengths for all color regions of the feathers' eyespots, with the green color regions emitting the most intense laser light. The team thinks their work could lead to the development of biocompatible lasers that could safely be embedded in the human body for sensing, imaging, and therapeutic purposes.

Stocks Rally as AI Titans Lead Nasdaq Surge, Figma IPO Adds Fuel to Tech Momentum

U.S. stocks opened higher Thursday, powered by stellar earnings from Microsoft and Meta Platforms and the blockbuster public debut of design software firm Figma. The Nasdaq soared 1.52%, while the S&P 500 advanced 0.79%. The Dow added 0.17%.

Figma makes its long-awaited entrance onto the NYSE under the ticker FIG, pricing its IPO at $33 per share—above its initial $25–$28 range—and raising $1.2 billion. The offering was nearly 40 times oversubscribed, reflecting exceptional investor demand. The stock is seen as a bellwether for the broader tech IPO market, with the company valued near $19.5 billion—just shy of Adobe’s failed $20 billion takeover attempt in 2023.

Figma’s strong debut underscores growing appetite for high-growth, AI-enabled tech firms. “These might be some of the best financials we’ve seen this year,” said Dean Quiambao, Technology Industry Leader at Armanino, citing Figma’s 46% revenue growth and 91% gross margin.

Meanwhile, the Nasdaq rally was led by Big Tech after what analysts described as “mic drop results” from Microsoft and Meta.

White House Crypto Report a Mixed Bag for Bitcoin Advocates

The White House released its long-awaited report on crypto on Wednesday, detailing a number of policy recommendations that omitted a Bitcoin reserve.

The 166-page document provides recommendations for multiple aspects of the crypto industry, including banking policy, stablecoins and countering illicit finance. The report does mention the Strategic Bitcoin Reserve, insofar as it was established back in March, but makes no mention of further development.

Bitcoin maximalists have stated that the Bitcoin reserve order should allow the government to actively purchase the asset in a strategy more akin to El Salvador.

While the crypto industry has largely welcomed the report and its potential effect on blockchain policymaking, others believe the lack of action on a Bitcoin reserve is a missed opportunity.

“Markets were watching for leadership and instead got ambiguity," said CJ Burnett, chief revenue officer of Compass Mining, a U.S.-based crypto mining hosting firm with operations in Ohio and Texas.
