Updating Turing's Model of Pattern Formation

New research revisits the Turing instability mechanism; proving mathematically how the instabilities which give rise to patterns can occur through simple reactions, and in widely varied environmental ...

Scientists Use CRISPR to Knock Down Gene Messages Early in Development

Researchers have harnessed the technology to target gene messages (messenger RNA) involved in early vertebrate ...

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 ...

Autism: How a Gene Alteration Modifies Social Behavior

A team of researchers has discovered a new connection between a genetic alteration and social difficulties related to autism: A mutation in the neuroligin-3 gene reduces the effect of the hormone ...

Decline in Plant Breeding Programs Could Impact Food Security

A team of scientists led by a horticulture professor who leads a pome fruit (apples and pears) breeding program, found that public plant breeding programs are seeing decreases in funding and ...

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 ...

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 ...

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 ...

Herbicide Harming Marsupial Health and Development, Research Finds

Researchers exposed the adult female tammar wallabies to atrazine contaminated water throughout pregnancy, birth and lactation to help establish the extent of harm being caused by the chemical. They ...

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 ...

Land Use Changes May Increase Disease Outbreak Risks

Global changes in land use are disrupting the balance of wild animal communities in our environment, and species that carry diseases known to infect humans appear to be benefiting, finds a new ...

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 ...

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 ...

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 ...

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 ...

Key Brain Region Was 'Recycled' as Humans Developed the Ability to Read

A new study offers evidence that the brain's inferotemporal cortex, which is specialized to perform object recognition, has been repurposed for a key component of reading called orthographic ...

Studies Shed New Light on How Biodiversity Influences Plant Decay

Scientists have provided new insights on the relationship between plant diversity in forests and the diversity of organisms involved in their decay, such as bacteria and ...

Cell Diversity in the Embryo

Epigenetic factors control the development of an ...

Between Shark and Ray: The Evolutionary Advantage of the Sea Angels

Angel sharks are sharks, but with their peculiarly flat body they rather resemble rays. An international research team has now investigated the origin of this body shape. The results illustrate how ...

The Wrong Track: How Papillomaviruses Trick the Immune System

Specific antibodies protect us against viral infections - or do they not? Researchers studied the immune response to papillomaviruses in mice and discovered a hitherto unknown mechanism by which the ...
