Twin Moons of Dinkinesh: NASA’s Lucy Unveils a Surprising Discovery
NASA’s Lucy spacecraft’s November 2023 flyby of asteroid Dinkinesh revealed significant geological features indicating its internal strength and complex history. Images showed a trough, a ridge, and a contact binary satellite, Selam. These findings, suggesting that Dinkinesh responded dynamically to stress over millions of years, help scientists understand the formation and evolution of small bodies in the solar system.
Images from the November 2023 flyby of asteroid Dinkinesh by NASA’s Lucy spacecraft reveal intriguing details. They show a trough on Dinkinesh where a large piece — about a quarter of the asteroid — suddenly shifted, a ridge, and a separate contact binary satellite (now known as Selam). Scientists say this complicated structure shows that Dinkinesh and Selam have significant internal strength and a complex, dynamic history.

Phoenix Rises: ‘Weird’ New Planet Defies Expectations
Phoenix, an exoplanet defying usual degradation by its nearby red giant, retains a thick atmosphere, upending assumptions about atmospheric loss and planetary decay in harsh stellar environments.
A unique exoplanet was discovered that should have been stripped down to bare rock by its nearby host star’s intense radiation, but somehow grew a puffy atmosphere instead. This is the latest in a string of discoveries forcing scientists to rethink theories about how planets age and die in extreme environments.
Nicknamed “Phoenix” for its ability to survive the radiant energy from its red giant star, the newly discovered planet illustrates the vast diversity of solar systems and the complexity of planetary evolution—especially at the end of stars’ lives.

Scientists Discover Naturally Occurring Gut Molecule That Can Prevent and Treat the Flu
Researchers at the State University of Campinas in Brazil and the Pasteur Institute in Lille, France, conducted experiments on mice and discovered that administering a specific substance reduced both viral load and inflammation in animals infected with the influenza virus.
According to a study published in the journal Gut Microbes, researchers from the State University of Campinas (UNICAMP) in São Paulo, Brazil, and Pasteur Institut in Lille, France, have found that a naturally occurring gut molecule can prevent and even treat influenza.
Experiments with mice showed a fall in levels of the molecule indole-3-propionic acid (IPA) during infection by influenza virus H3N2.

Harnessing Nature’s Genius: Scientists Uncover Secret Mechanics of Fire Ant Rafts
A new study examines the way ant ‘rafts’ come together to ensure survival during floods.
Fire ants form rafts to survive flooding, but how do those bonds work? And what can we learn from them? A Binghamton University, State University of New York professor is researching those questions to expand our knowledge of materials science.
When flooding hits a region where fire ants live, their survival response is to latch together to form a buoyant “raft” that floats and keeps the colony united. Think of it like a condensed, adaptive material where the building blocks — individual ants — are actually alive.

Chemists Discover How Platinum Catalysts Assemble and Disassemble Themselves
Combination of techniques reveals how a nanoparticle catalyst forms from individual atoms during operation and subsequently breaks down for recycling.
Researchers at the U.S. Department of Energy’s Brookhaven National Laboratory and Stony Brook University, along with their partners, have made significant discoveries regarding the reversible assembly and disassembly of a platinum catalyst. This new insight could provide information about the catalyst’s stability and potential for reuse. Their recent study, published in the journal Nanoscale, explores how individual platinum atoms on a cerium oxide base come together to form active catalytic nanoparticles during reactions. Intriguingly, these particles then break apart when the reaction ceases.

Old Genes, New Tricks: The Science of Suspended Animation in Killifish
How Killifish Embryos Use Suspended Animation To Survive Over 8 Months of Drought
The African turquoise killifish utilizes a unique survival strategy through diapause, leveraging ancient genes to endure dry seasons. This mechanism involves pausing embryonic development, which is later resumed. Research also indicates similar genetic patterns in other species, suggesting a shared evolutionary trait for suspended animation.

Revolutionary New Pest Control Tool Discovered by Johns Hopkins
A Johns Hopkins study revealed that an enzyme in fruit fly testes could hinder insect reproduction by managing bromotyrosine accumulation, presenting a novel method for managing pests that threaten agriculture and spread diseases.
A novel way to curb nagging insects has been flying under our radar—an enzyme from fruit fly testes.
The compound could control bugs that carry disease and harm crops by stunting their ability to procreate, according to new research by Johns Hopkins University.

Female Brains Have More “Old” Cells, Alzheimer’s Study Finds
Engineers at the University of California San Diego have found that certain brain cells age faster than others and are more common in people with Alzheimer’s disease. They also noted differences in the aging of specific brain cells between sexes, with the female cortex showing a greater proportion of “old” oligodendrocytes relative to “old” neurons compared to the male cortex.
The discoveries were made possible by a new technique called MUSIC (multinucleic acid interaction mapping in single cells), which allows researchers to peek inside individual brain cells and map out interactions between chromatin—which is the tightly coiled form of DNA—and RNA. This technique enables researchers to visualize these interactions at single-cell resolution, as well as study how they influence gene expression.

Record-Breaking Galactic Discovery: Webb Space Telescope’s Glimpse of Cosmic Dawn
NASA’s James Webb Telescope discovers a distant galaxy at redshift 14.32, suggesting unexpectedly rapid galaxy formation just 290 million years after the Big Bang.
Over the past two years, scientists have used NASA’s James Webb Space Telescope (also called Webb or JWST) to explore what astronomers refer to as Cosmic Dawn – the period in the first few hundred million years after the Big Bang where the first galaxies were born. These galaxies provide vital insight into the ways in which the gas, stars, and black holes were changing when the universe was very young.
In October 2023 and January 2024, an international team of astronomers used Webb to observe galaxies as part of the JWST Advanced Deep Extragalactic Survey (JADES) program. Using Webb’s NIRSpec (Near-Infrared Spectrograph), they obtained a spectrum of a record-breaking galaxy observed only two hundred and ninety million years after the Big Bang. This corresponds to a redshift of about 14, which is a measure of how much a galaxy’s light is stretched by the expansion of the universe.

Ancient Porcupine Discovery Solves Evolutionary Mystery 10 Million Years in the Making
New findings from a complete porcupine skeleton in Florida reveal a much earlier origin for North American porcupines, predating the Isthmus of Panama, and suggest a mixed evolutionary lineage with traits of both North and South American species.
There’s a longstanding debate simmering among biologists who study porcupines. In Central and South America, there are 16 species of porcupines, while North America has just one. Genetic data indicates that this lone North American porcupine is part of a lineage that dates back 10 million years. However, fossil records provide a contrasting narrative, suggesting that they might have evolved only 2.5 million years ago, at the beginning of the ice ages.
