A research team has successfully implemented a programmable spinor lattice on a photonic integrated circuit (PIC). This platform enables the realization of non-Abelian physics, in which the outcome of operations depends on their sequence, within an integrated photonic system.
Supermassive black hole binaries form naturally when galaxies merge, but scientists have only confidently observed a very few of these systems that are widely separated. Black hole binaries that closely orbit each other have not yet been measured. In a paper published today in
The Environmental Protection Agency on Thursday revoked its own 2009 "endangerment finding," a scientific conclusion that for 16 years has been the central basis for regulating planet-warming emissions from power plants, vehicles and other sources.
Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize itself into a complex organism. It underpins the diversity in the animal kingdom, from insects to frogs, to humans. But how do cells establish and
The Yangtze River Basin, a global biodiversity hotspot, has endured severe ecological degradation over several decades due to intense human activity, leading to a marked decline in aquatic biodiversity. In order to halt this 70-year trend, the Chinese government instituted a

While most of the world's glaciers are retreating as the climate warms, a small but significant population behaves very differently—and the consequences can be severe. A team of international scientists, led by the University of Portsmouth, has carried out a comprehensive
The EPA has scrapped a rule stating that climate change harms human health. Here’s what that could mean
As ocean temperatures rise due to climate change, corals and other sensitive organisms survive where temperatures are less extreme. But a new study from researchers at Florida Tech, published this month in the journal Communications Earth & Environment, found that local land
Physicists in Leiden have built a microscope that can measure no fewer than four key properties of a material in a single scan, all with nanoscale precision. The instrument can even examine complete quantum chips, accelerating research and innovation in the field of quantum
Using advanced machine learning and climate models, researchers have shown that the ancestors of crops like wheat, barley, and rye probably were much less widespread in the Middle East 12,000 years ago than previously believed. This challenges traditional assumptions about the
The currents of the oceans, the roiling surface of the sun, and the clouds of smoke billowing off a forest fire—all are governed by the same laws of physics and give rise to a complex phenomenon known as turbulence. But precisely modeling this chaotic motion of fluids,
Freshwater streams, ponds and lakes across the United States are becoming saltier, and new research from the University of Missouri shows the damage may be greater than scientists once thought. Scientists at Mizzou's College of Agriculture, Food and Natural Resources found that
The Trump administration on Thursday revoked a scientific finding that long has been the central basis for U.S. action to regulate greenhouse gas emissions and fight climate change, the most aggressive move by the president to roll back climate regulations.
Four worlds around a small, dim star are challenging theories of planet formation
Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's transformation into a black hole, allowing astronomers to construct a
Scientists have identified a crucial mechanism that allows plants to shape their vascular systems, determining whether they grow soft edible storage organs or develop the rigid woody tissue characteristic of trees. Published in Science, research led by the University of
A global team of astronomers, led by the University of Warwick, have used a European Space Agency (ESA) telescope to discover a planetary system that turns our understanding of planet formation upside down, with a distant rocky world. In our solar system, the inner planets
Some genetic mutations that are expected to completely stop a gene from working surprisingly cause only mild or even no symptoms. Researchers in previous studies have discovered one reason why: cells can ramp up the activity of other genes that perform similar functions to make
Billions of American chestnut trees once covered the eastern United States. They soared in height, producing so many nuts that sellers moved them by train car. Every Christmas, they're called to mind by the holiday lyric "chestnuts roasting on an open fire."
A new study from an interdisciplinary German research collaboration, led by the Haptic Intelligence Department at the Max Planck Institute for Intelligent Systems (MPI-IS), reveals the secret to the gentle dexterity of the elephant trunk. The 1,000 whiskers that cover an
A rocky exoplanet in the LHS 1903 system defies planet formation models, hinting that gravitational upheaval reshaped the red dwarf’s four worlds.
Pachyderm whiskers are more flexible at the tip than the base, allowing elephants to complete delicate tasks with their incredibly strong trunks

New analysis on 2017 Hubble images of the Jupiter-family comet, 41P/Tuttle–Giacobini–Kresak (41P/TGK), indicates that the comet underwent a spin reversal between April and December 2017. While this behavior is not unheard of, 41P/TGK's rotational changes were deemed
An international team of scientists has discovered that a small, low-abundance protein plays a surprisingly big role in assembling carboxysomes—specialized bacterial microcompartments that enable efficient carbon fixation and underpin much of life on Earth. The study, published
It is well documented that the Gulf Stream plays a pivotal role in the climate system through its transfer of heat, which ultimately supplies warmth to northern latitudes in the North Atlantic. What remains less well understood is how the Gulf Stream influences the climate
DNA, the blueprint of life, is best known for its fundamental role as genetic material—storing and transmitting biological information through the precise sequence of its bases. For decades, this information-storage function has defined how we think about DNA. But what if DNA
New research has found that we are more likely to back policies aimed at tackling climate change when we feel fearful, but feelings of dread make us less likely to support such policies.
