When Jasper Baur was a freshman at New York's Binghamton University, his interests centered on earth sciences. Then he got involved in a seemingly unrelated pursuit: harnessing drone-mounted geophysical instruments to aid in the slow, dangerous work of detecting land mines.
Nicotine, a potent insecticidal alkaloid unique to the nightshade family, has been employed in agriculture as a pesticide since 1690. It also has therapeutic potential for neurological disorders such as Alzheimer's disease, Parkinson's disease, and depression. Despite its
We associate nests with shelter, warmth, and a safe retreat—and usually picture a bird's nest made out of twigs, grass and feathers. Yet many other animals take advantage of such refuges, with nests being built by a diversity of species ranging from termites to great apes,
Elements essential to life, such as carbon, nitrogen, oxygen, phosphorus, and sulfur, were "delivered" to Earth and the moon during the early stages of the solar system via asteroids and comets impacting their surfaces. These exogenous materials may have provided the chemical
Crystals, bacterial colonies, flame fronts: the growth of surfaces was first described in the 1980s by the Kardar–Parisi–Zhang equation. Since then, it has been regarded as a fundamental model in physics, with implications for mathematics, biology, and computer science.
U.S. cities are rapidly becoming urban heat islands, where these cities are significantly warmer than their surrounding area. Vast expanses of asphalt and concrete trap heat, while large, densely packed buildings disrupt wind flow and intensify the effect. But beyond parking
On the shores of the west coast of Australia lies a window to our past: the stromatolites and microbial mats of Gathaagudu (Shark Bay).

The halomethane compound bromoform (CHBr3) has devastating effects on the ozone layer. In the upper layers of the atmosphere, bromoform reacts with UV radiation, releasing bromine molecules which destroy ozone molecules. This reaction, however, has long puzzled scientists; the
There are many poorly understood links in the food web, often referred to as trophic relationships. Out in East Antarctica, a previously unconfirmed link between sea snails and Adélie penguins might reveal more than meets the eye for the Southern Ocean ecosystem.
Iron and oxygen bind together throughout the body. Most famously, iron binds dioxygen, or two oxygens paired with each other, in hemoglobin that transports oxygen through blood. But iron-oxo compounds, as they're called, are found in many other places throughout the body. For
After months of relentlessly miserable weather for most of the UK, spring brings renewed enthusiasm for spending time outdoors hiking, wild swimming, paddling, or on walks.

Observations conducted with the Subaru Telescope and its first-generation wide-field camera, Suprime-Cam, have revealed new insights into the relationship between the color and size of Jupiter Trojan asteroids.
We thought it was evolution, but an experiment with pencils shows that tips like teeth and thorns may owe their rounded shape to mechanical wear. Most of us have been stung by a bee, bitten by an animal, or scratched by a thorny bush. But very few of us have probably taken a
What if the Trojan horse had been pulled to pieces, revealing the ruse and fending off the invasion, just as it entered the gates of Troy? That's an apt description of a newly characterized bacterial defense system that chops up foreign DNA. Bacteria and the viruses that infect
Along the southern coastline, researchers dive deep to collect seaweed from kelp forests and rocky platforms, taking small samples and the location of each sample. Back in the lab, the specimens are preserved—some dried, others kept alive—so they can be studied, cultured and
Some cats will suddenly refuse to touch brands of cat food that they have eaten for years. Changing the way the food smells might solve the problem

Tropical trees are better neighbors than trees in temperate forests, according to a study published in the journal Nature by researchers from 29 different institutions including the Smithsonian Tropical Research Institute (STRI) and the ForestGEO global network of forest
A study published in Azania: Archaeological Research in Africa sheds new light on the westward spread of pearl millet (Pennisetum glaucum) agriculture in prehistoric West Africa. A recent survey documented its earliest known occurrence in the Lac de Guiers basin of Northern
Rapid ocean warming is likely to make tropical cyclone rainfall more intense and longer lasting, increasing flood risks in parts of the North Atlantic region. A new study led by Newcastle University using satellite data shows that tropical cyclones and their post-tropical
Thirty-four years after Cornell University scientists first conceived it, the Fred Young Submillimeter Telescope (FYST) now rises above the Atacama Desert, near the summit of Cerro Chajnantor in Chile. FYST will help answer some of the most important questions in astronomy,
Researchers from the Monash University School of Physics and Astronomy have flipped a long-held assumption in optics, showing that deliberately introducing controlled disorder into ultra-thin optical devices can dramatically increase their power and versatility, without making

When we watch videos or ask AI questions, enormous amounts of data are constantly moving inside computers. In particular, data centers that support AI must process and transfer vast amounts of data at very high speeds. However, current computers have a fundamental limitation:
Roman painters commissioned at the end of the 1st century to decorate the walls of the Domus of Salvius in present-day Cartagena could hardly have imagined that their technical expertise would still attract attention twenty centuries later. Analysis of wall paintings from one
As the Orion spacecraft hurtles home, friction caused by reentry into Earth's atmosphere will drastically decrease its speed from a potential 25,000 miles per hour (40,000 kilometers per hour).
A handful of plankton fossils buried in a small chunk of rock show that the oceans were teeming with life before the Late Ordovician mass extinction, the second most severe on record
Cases of Borna disease virus 1 (BoDV-1) are extremely rare in humans, but in those who develop disease, the outcome is severe, almost always resulting in fatal encephalitis or inflammation in the brain. This zoonotic virus belongs to the order Mononegavirales, which includes
Intracellular transport is a vital process that allows cells to move proteins and other molecules to specific locations. This process is especially important in neurons, which have highly polarized structures with long extensions such as axons and dendrites. For neurons to
From the Wright brothers' first flight to the speedy development of COVID-19 vaccines, collaboration has been key to innovation. Paradoxically, even competitors can benefit from collaboration—when they hold different pieces of the same puzzle.
Most polychaete species spend their lives in burrows in the seabed. However, adult individuals of two species, Alitta succinea and Platynereis dumerilii, leave their burrows to spawn during warm summer nights around the full moon.
Millions of students nationwide use text-supplemented audiobooks, learning tools that are thought to help those who struggle with reading keep up in the classroom. A new study by scientists at MIT's McGovern Institute for Brain Research finds that many students do benefit from
A lot of research goes into determining how to best predict the next eruption of the Yellowstone supervolcano. Part of this involves pinning down how the magma migration system functions and evolves over time. The exact mechanism driving Yellowstone's volcanism and how magma
A new type of radiofrequency trap can capture particles with extremely different requirements and could theoretically hold both types of particles at the same time. Researchers in the group of Professor Dmitry Budker from the PRISMA++ Cluster of Excellence and the Helmholtz
Inspired by the collective dynamics of bacteria like E. coli and Bacillus subtilis, researchers at the University of Twente asked a simple but fundamental question: what happens when artificial swimmers are made rod-shaped rather than spherical, and how does shape control how
Restoring forests, wetlands and peatlands could help defend national borders as well as tackle climate change, according to new research from the University of East London (UEL). The study introduces the concept of "defensive rewilding"—the intentional, pre- or mid-conflict
Supereruptions are extremely large volcanic eruptions that eject more than 1,000 cubic kilometers of magma, rock and ash. They are among the most hazardous geological events on Earth and have profound impacts on the environment, climate, and human society. For this reason,
