Tiny protein pairs may hold the secret to life’s origin
A team from the University of Illinois has uncovered surprising evolutionary links between the genetic code and tiny protein fragments called dipeptides. By analyzing billions of dipeptide sequences across thousands of species, the researchers revealed that these molecular pairs trace the earliest steps in the origin of life.

Soil warming experiments challenge assumptions about climate change
Heating alone won’t drive soil microbes to release more carbon dioxide — they need added carbon and nutrients to thrive. This finding challenges assumptions about how climate warming influences soil emissions.

Scientists just found the “master switch” for plant growth
Scientists at Cold Spring Harbor Laboratory have cracked open the secrets of plant stem cells, mapping key genetic regulators in maize and Arabidopsis. By using single-cell RNA sequencing, they created a gene expression atlas that identifies rare stem cell regulators, links them to crop size and productivity, and offers a new roadmap for breeding resilient, high-yield plants.

A volcano erased an island’s plants. Their DNA revealed how life starts over
Volcanic eruptions on the remote island of Nishinoshima repeatedly wipe the land clean, giving scientists a rare chance to study life’s earliest stages. Researchers traced the genetic origins of an extinct purslane population to nearby Chichijima but found striking quirks—evidence of a founder’s effect and genetic drift. These discoveries shed light on how plants recolonize harsh environments and how ecosystems evolve from scratch.

Scientists are closing in on Leonardo da Vinci’s DNA
A groundbreaking project is piecing together Leonardo da Vinci’s genetic profile by tracing his lineage across 21 generations and comparing DNA from living descendants with remains in a Da Vinci family tomb. If successful, the effort could reveal new insights into Leonardo’s health, creativity, and even help confirm the authenticity of his works.

Who are the Papua New Guineans? New DNA study reveals stunning origins
On remote islands of Papua New Guinea, people carry a story that ties us all back to our deepest roots. Although their striking appearance once puzzled scientists, new genetic evidence shows they share a common ancestry with other Asians, shaped by isolation, adaptation, and even interbreeding with mysterious Denisovans. Yet, their unique history — marked by survival bottlenecks and separation from farming-driven booms — leaves open questions about the earliest migrations out of Africa and whether their lineage holds traces of a forgotten branch of humanity.

Scientists just found hidden parasitic wasps spreading across the U. S.
Researchers discovered two new parasitic wasp species living in the U.S., tracing their origins back to Europe and uncovering clues about how they spread. Their arrival raises fresh questions about biodiversity, ecological risks, and the role of citizen science in tracking hidden species.

150-million-year-old teeth expose dinosaurs’ secret diets
By analyzing tooth enamel chemistry, scientists uncovered proof that Jurassic dinosaurs divided up their meals in surprising ways—some choosing buds and leaves, others woody bark, and still others a mixed menu. This dietary diversity helped massive plant-eaters coexist, while predators carved out their own niches.

The sweetpotato’s DNA turned out stranger than anyone expected
Sweetpotato, a critical food crop for millions, has finally had its genetic code fully decoded after decades of mystery. Scientists unraveled its extraordinarily complex genome of six chromosome sets, revealing a hybrid origin stitched together from multiple wild ancestors. This achievement not only sheds light on sweetpotato’s remarkable adaptability and resilience but also provides powerful tools for breeders to create higher-yielding, more nutritious, and climate-resistant varieties.

No one knows what these strange larvae grow into
Not all barnacles just sit on rocks and ships. Some invade crabs, growing like a parasitic root system that hijacks their bodies. A mysterious group called y-larvae has baffled scientists for over a century, with no known adult stage. Genetic evidence now reveals they’re related to barnacles and may also be parasites — lurking unseen inside other creatures.

Scientists just discovered how octopuses really use their arms
Octopuses aren’t just flexible—they’re astonishingly strategic. A new study reveals how their eight arms coordinate with surprising precision: front arms for exploring, back arms for locomotion, and every arm capable of twisting, bending, shortening, and elongating in unique ways. Researchers observed nearly 7,000 deformations across multiple habitats, capturing behaviors from camouflage tricks to elaborate hunting techniques. This insight doesn’t just unlock secrets of octopus biology, it could also inspire new innovations in robotics and neuroscience.

Tiny skaters beneath the arctic ice rewrite the limits of life
Hidden within Arctic ice, diatoms are proving to be anything but dormant. New Stanford research shows these glass-walled algae glide through frozen channels at record-breaking subzero temperatures, powered by mucus-like ropes and molecular motors. Their astonishing resilience raises questions about how life adapts in extreme conditions and highlights the urgency of studying polar ecosystems before they vanish.

Don’t toss cannabis leaves. Scientists just found rare compounds inside
Scientists at Stellenbosch University have uncovered a rare class of plant compounds, flavoalkaloids, in Cannabis leaves for the first time. Using advanced two-dimensional chromatography and mass spectrometry, they identified 79 phenolic compounds across three strains, 25 of which had never before been reported in Cannabis. The surprising discovery highlights the complexity of the plant and its untapped biomedical potential beyond cannabinoids, opening new doors for research and medicine.
