AI and Crypto Companies Dominated IPO Winners in 2025
The drought in initial public offerings ended this year, led by big winners in AI and crypto, but gains were rare for companies outside those industries. Bankers expect those trends to hold in 2026. Booms in AI and crypto delivered two of the biggest winners of the year: data center developer ...

Global lead exposure still costs trillions and endangers children, study finds
Lead poisoning was once thought to largely be a problem of the past, as the globe gradually weaned itself off leaded gasoline in road vehicles in 2021. But has global lead pollution truly been resolved?

Es geht um das automatisierte Erkennen von Emotionen in Gesichtern: »Wie gesehen, fußen viele der für das ganze Gebiet maßgeblichen Datensätze darauf, dass Schauspieler für die Kamera mimisch darstellen. Das bedeutet, dass KI-Systeme auf das Erkennen unechter Gefühlsausdrücke trainiert werden. Sie behaupten also zwar, Zugang zu Grundwahrheiten über natürliche innere Zustände zu haben, aber ihr Trainingsmaterial ist zwangsläufig unauthentisch.«

Bird-like robot with novel wing system achieves self-takeoff and low-speed flight
In 2021, a group of scientists from China engineered the RoboFalcon—a bird-inspired flapping-wing robot with a newly engineered mechanism made to drive bat-style morphing wings capable of flight. While this bio-inspired robot performed well at a cruising speed, it was not capable of flying at lower speeds or achieving takeoff without assistance.

DRC finally moves to protect African gray parrots from unsustainable trade
LUBUMBASHI, DRC — African gray parrot populations in the central and northern parts of the Democratic Republic of Congo are declining. Data collected by patrols carried out by the Lukuru Foundation in Lomami Luidjo, Maniema province, show a worrying decline of 36% in the numbers of Psittacus erithacus observed between 2016 and 2021. In August […]

This fall, Americans got to see what it’s like to go without a safety net for the hungry.
With the U.S. government shut down for multiple weeks
and Donald Trump refusing to fund SNAP, the federal food stamp program,
a panic set inamong the more than 40 million people who rely on it.
Families skipped meals,
and babies went unfed.
Food banks ran out of food, and some people turned to dumpster diving.
It was just a glimpse of what’s to come.

Wave of Tax Cuts Has Left Many States Vulnerable to Trump SNAP and Medicaid Crisis
President Donald Trump’s so-called One Big Beautiful Bill Act will shift billions in costs for SNAP and Medicaid to states. But with 26 having cut or eliminated state income taxes just since 2021, they may not have the money to continue the programs.

Adversarial Defense in Cybersecurity: A Systematic Review of GANs for Threat Detection and Mitigation
Machine learning-based cybersecurity systems are highly vulnerable to adversarial attacks, while Generative Adversarial Networks (GANs) act as both powerful attack enablers and promising defenses. This survey systematically reviews GAN-based adversarial defenses in cybersecurity (2021--August 31, 2025), consolidating recent progress, identifying gaps, and outlining future directions. Using a PRISMA-compliant systematic literature review protocol, we searched five major digital libraries. From 8…

Variations of the vector magnetic structures in the solar polar regions observed by Hinode
Using the polar vector magnetic field data observed by Hinode from 2012 to 2021, we study the long-term variations of the magnetic flux, the flux proportion of different polarities, and the magnetic inclination with respect to the local normal in the solar polar regions above 70 degree latitude during solar cycle 24. In both polar regions after the polarity reversal, the unsigned magnetic fluxes of the dominant polarity increased to a peak of about 1.3$\times$10$^{22}$ Mx during the solar minim…

Vaccinating Now or Vaccinating Later: Separating Pull-Forward and Net Effects Using a Dynamic Regression Discontinuity Design
We study the impact of a novel COVID-19 vaccine mandate, targeting graduating high-school students, on first vaccine uptake. In 2021, the State Government of Western Australia (WA) required attendees at "Leavers" -- a large-scale state-supported graduation party held annually in November in a WA regional town -- to be vaccinated. Using administrative data that link date-of-birth (at the month level), school attendance, and first-dose vaccination records, we exploit the strict school-age laws in…
