How a leaf's symmetry and lobes impact its journey back to the tree

How a leaf's symmetry and lobes impact its journey back to the tree

Two physicists from the Technical University of Denmark have found that leaf shape is a determining factor in the distance leaves travel as they fall from their tree. In their paper published in the Journal of the Royal Society Interface, Matthew Dominic Biviano and Kaare Hartvig Jensen describe how they built a device that allowed them to mass-test falling leaves and what they learned through its use.

How a flexible protein domain links gene transcription and RNA processing

How a flexible protein domain links gene transcription and RNA processing

In a new study published in Cell Reports, researchers at the University of Freiburg reveal how a disordered protein segment helps connect two key steps of gene expression: the reading of genes and the editing of their RNA products.

A new study provides insights into cleaning up noise in quantum entanglement

A new study provides insights into cleaning up noise in quantum entanglement

Quantum entanglement—a connection between particles that produces correlations beyond what is classically possible—will be the backbone of future quantum technologies, including secure communication, cloud quantum computing, and distributed sensing. But entanglement is fragile; noise from the environment degrades entangled states over time, leaving scientists searching for methods to improve the fidelity of noisy entangled states.

Artificial intelligence and genetics can help farmers grow corn with less fertilizer

Artificial intelligence and genetics can help farmers grow corn with less fertilizer

New York University scientists are using artificial intelligence to determine which genes collectively govern nitrogen use efficiency in plants such as corn, with the goal of helping farmers improve their crop yields and minimize the cost of nitrogen fertilizers.

Satellite data from ship captures landslide-generated tsunami for the first time

Satellite data from ship captures landslide-generated tsunami for the first time

Landslide-generated tsunamis pose a serious risk to coastal communities, particularly within narrow fjords where tall cliffs can trap and amplify waves. Scientists rely heavily on earthquake-based observation systems to issue tsunami warnings, but these methods don't always capture localized ground movement caused by landslides.

Q&A: A generative AI technique for designing RNA with improved function

Q&A: A generative AI technique for designing RNA with improved function

Ribonucleic acid, also called RNA, is a molecule present in all living cells. It plays a critical role in transmitting genetic instructions from DNA and creating proteins. With the power to execute a plethora of functions, the little RNA "messenger" has led to important innovations across therapeutics, diagnostics, and vaccines, and made us rethink our understanding of life itself.

Reexamining a receptor linked to sepsis resolves contradictions regarding its binding interactions

Reexamining a receptor linked to sepsis resolves contradictions regarding its binding interactions

After earning notoriety as the first cellular receptor isolated and mammalian lectin identified, the Ashwell-Morell receptor's functions in our bodies eluded scientists for more than 30 years.

Voyager 1 revives backup thrusters before command pause

Voyager 1 revives backup thrusters before command pause

Engineers at NASA's Jet Propulsion Laboratory in Southern California have revived a set of thrusters aboard the Voyager 1 spacecraft that had been considered inoperable since 2004. Fixing the thrusters required creativity and risk, but the team wants to have them available as a backup to a set of active thrusters whose fuel tubes are experiencing a buildup of residue that could cause them to stop working as early as this fall.

Perseverance Mars rover captures first visible-light auroras during intense solar storm

Perseverance Mars rover captures first visible-light auroras during intense solar storm

On March 15, 2024, near the peak of the current solar cycle, the sun produced a solar flare and an accompanying coronal mass ejection (CME), a massive explosion of gas and magnetic energy that carries with it large amounts of solar energetic particles. This solar activity led to stunning auroras across the solar system, including at Mars, where NASA's Perseverance Mars rover made history by detecting them for the first time from the surface of another planet.
