Groundbreaking Quantum Leap: Physicists Turn
Schrödinger’s Cat on Its Head
"Researchers from the University of Warsaw’s Faculty of
Physics, in collaboration with experts from the QOT Centre
for Quantum Optical Technologies, have pioneered an
innovative technique that allows the fractional Fourier
Transform of optical pulses to be performed using quantum
memory."

Alan Turing and the Power of Negative Thinking
"Mathematical proofs based on a technique called
diagonalization can be relentlessly contrarian, but they
help reveal the limits of algorithms."

Space’s Silent Threat: Scientists Shed New
Light on “Killer Electrons”
"High-energy ‘relativistic’ electrons, often called “killer”
electrons, are a major source of radiation damage to
satellites so understanding their patterns of activity is
crucial."

Human and ape ancestors arose in Europe, not
in Africa, controversial study claims
"A newly described fossil suggests that the ancestor of
humans and apes arose in Europe, not in Africa."

The first observation of neutrinos at CERN's
Large Hadron Collider
"A long-standing goal in this field of study was to observe
neutrinos inside colliders, particle accelerators in which
two beams of particles collide with each other."

Sporting Science
"The culture of censorship, which was prominently displayed
in my New York Times Magazine profile, is out of step with
the open-mindedness required in science."

Math Proof Draws New Boundaries Around Black
Hole Formation
"For a half century, mathematicians have tried to define the
exact circumstances under which a black hole is destined to
exist. A new proof shows how a cube can help answer the
question."

Viral Superconductor Sensation May Not Be The
Real Deal, Experts Say
"Late last month, a little-known group of South Korean
physicists posted a preprint study - which has not been
peer-reviewed - announcing that their material, called
LK-99, can superconduct at room temperatures and ambient
pressure."

Two Students Unravel a Widely Believed Math
Conjecture
"Mathematicians thought they were on the cusp of proving a
conjecture about the ancient structures known as Apollonian
circles. But a summer project would lead to its downfall."

"Researchers observe an effect in the quantum world that
does not exist in the macrocosm."

Matter Theories
"International research led by the Instituto de Astrofísica
de Canarias (IAC) and the University of La Laguna (ULL) has
found the first evidence of a massive galaxy with no dark
matter."

How to Build a Big Prime Number
"A new algorithm brings together the advantages of
randomness and deterministic processes to reliably
construct large prime numbers."

The Lawlessness of Large Numbers
"Mathematicians can often figure out what happens as
quantities grow infinitely large. What about when they are
just a little big?"

Faster
sorting algorithms discovered using deep reinforcement
learning
"Human intuition and know-how have been crucial in
improving algorithms. However, many algorithms have
reached a stage whereby human experts have not been able
to optimize them further."

A Compact Fusion Reactor Barely 3 Feet Across
Has Hit a Huge Milestone
"Ions inside a compact fusion reactor barely a meter (less
than 3 feet) across have been heated to the magic figure
of 100 million degrees Celsius (some 180 million degrees
Fahrenheit) for the first time in a monumental step
towards making nuclear fusion energy a practical reality."
