Origins of Life: Chemical Evolution in a Tiny Gulf Stream

Chemical reactions driven by the geological conditions on the early Earth might have led to the prebiotic evolution of self-replicating molecules. Scientists now report on a hydrothermal mechanism ...

How Plants Distinguish Beneficial from Harmful Microbes

Plants recognize beneficial microbes and keep harmful ones out, which is important for healthy plants production and global food security. Scientists have now discovered how legumes use small, ...

New Insight Into the Evolution of Complex Life on Earth

A novel connection between primordial organisms and complex life has been discovered, as new evidence sheds light on the evolutionary origins of the cell division process that is fundamental to ...

Long-Term Human Impacts on Reef Fish

In a new study investigating human impacts on resource fish biomass on the Island of Hawai'i, researchers observed an alarming 45% decrease in fish biomass over a decade of surveys. The scientists ...

How Growth Rates Influence the Fitness of Bacteria

Bacteria are survival artists: When they get nutrition, they multiply rapidly, albeit they can also survive periods of hunger. But, when they grow too quickly, their ability to survive is hampered. ...

This Fruit Attracts Birds With an Unusual Way of Making Itself Metallic Blue

Instead of relying solely on pigments, the metallic blue fruits of Viburnum tinus use structural color to reflect blue light, a mechanism rarely seen in plants. Researchers show that the fruits use ...

Researchers Hope to Save Seabirds by Calculating the Value of Their Excrement

To raise awareness of the importance of seabirds to people and the ecosystems we depend on, a new article looks at something that most of us find off-putting: their feces. The researchers say that ...

Faster Rates of Evolution Are Linked to Tiny Genomes

Inside every cell lies a genome - a full set of DNA that contains the instructions for building an organism. Across the biological world, genomes show a staggering diversity in size but scientists ...

Fossil Mystery Solved: Super-Long-Necked Reptiles Lived in the Ocean, Not on Land

By CT scanning crushed fossilized skulls and digitally reassembling them, and by examining the fossils' growth rings, scientists were able to describe a new species of prehistoric sea creature. ...

Why the 'Wimpy' Y Chromosome Hasn't Evolved out of Existence

The Y chromosome has shrunken drastically over 200 million years of evolution. Even those who study it have used the word 'wimpy' to describe it, and yet it continues to stick around. An ...

Tasmanian Devil Research Offers New Insights for Tackling Cancer in Humans

Researchers found a single genetic mutation that leads to reduced growth of a transmissible cancer in Tasmanian devils in the wild. The finding gives hope for the animals' survival and could ...

Study Sheds New Light on Vein Formation in Plants

Researchers have found plant hormones known as strigolactones suppress the transportation of auxin, the main plant hormone involved in vein formation, so that vein formation occurs slower and with ...

Herbivores, Not Predators, Most at Risk of Extinction

One million years ago, the extinction of large-bodied plant-eaters changed the trajectory of life on Earth. The disappearance of these large herbivores reshaped plant life, altered fire regimes ...

New Guinea Has the World's Richest Island Flora

New Guinea is the most floristically diverse island in the world, an international collaboration has shown. The study presents a list of almost 14,000 plant species, compiled from online catalogues ...

Ocean Heatwaves Dramatically Shift Habitats

Marine heatwaves across the world's oceans can displace habitat for sea turtles, whales, and other marine life by 10s to thousands of kilometers. They dramatically shift these animals' ...

Dinosaur Relative's Genome Linked to Mammals: Curious Genome of Ancient Reptile

Biologists have sequenced the genome of the tuatara, a lizard-like creature that lives on the islands of New ...

Gut Microbes Shape Our Antibodies Before We Are Infected by Pathogens

Because the microbiota is so complex, containing hundreds of different bacterial species, it is not known how the presence of microbes in the intestine shaped the antibodies that are present even ...

Study Clarifies Kinship of Important Plant Group

Asterids comprise around 100,000 flowering plants, from heather to tomatoes. Up to now, their family relationships had not yet been fully clarified. A new study has now somewhat closed this knowledge ...

Discovery Could Lead to More Potent Garlic, Boosting Flavor and Bad Breath

Their work could boost the malodorous - yet delicious - characteristics that garlic-lovers the world over ...

Scientists Find How Clock Gene Wakes Up Green Algae

Researchers have found the mechanism of the night-to-day transition of the circadian rhythm in green algae. The findings could be applied to green algae to produce larger amounts of lipids, which are ...

Molecular Forces: The Surprising Stretching Behavior of DNA

Experiments with DNA molecules show that their mechanical properties are completely different from what those of macroscopic objects - and this has important consequences for biology and medicine. ...

Scientists Discover New Penguin Colonies from Space

A new study using satellite mapping technology reveals there are nearly 20% more emperor penguin colonies in Antarctica than was previously thought. The results provide an important benchmark for ...

Angels in Disguise: Angelfishes Hybridize More Than Any Other Coral Reef Species

A new study highlights the remarkably high incidence of and tendency toward hybridization in the angelfish family (even between divergent species), more so than in any other group of coral reef ...

Tool Could Improve Success in Translating Drugs from Animal Studies to Humans

A new computational tool could help better determine which drugs should move from animal testing to humans. It could also sooner detect a reason why a drug might fail, guiding how a clinical trial ...
