In a first, evolutionary biologists have identified a gene that influences visual preferences in tropical butterflies
Tropical Heliconius butterflies are well known for the bright color patterns on their wings. These striking color patterns not only scare off predators—the butterflies are poisonous and are distasteful to birds—but are also important signals duri.....»»
Genomic analysis of a species of zooplankton questions assumptions about speciation and gene regulation
When two animals look the same, eat the same, behave the same way, and live in similar environments, one might expect that they belong to the same species......»»
Cichlid fishes" curiosity promotes biodiversity: How exploratory behavior aids in ecological adaptation
Cichlid fishes exhibit differing degrees of curiosity. The cause for this lies in their genes, as reported by researchers from the University of Basel in the journal Science. This trait influences the cichlids' ability to adapt to new habitats......»»
First chromosome-level reference genomes of the ornamental banana and pink banana
The genus Musa, encompassing approximately 70 herbaceous species, is predominantly found in the tropical and subtropical regions of Asia and Oceania. This genus is renowned for being one of the most important food crops globally and popular ornamenta.....»»
Research show oysters could help clean up the reef through filtration
Scientists have found oysters could be very useful in gobbling up nutrient pollution from tropical waterways, including the Great Barrier Reef......»»
Uncovering the diversity of Micropsalliota: Seven new species and one newly recorded species in southern China
Species of Micropsalliota (Basidiomycota, Agaricomycetes, Agaricales, Agaricaceae) are mainly distributed in tropical and /or subtropical regions. These fungi are saprophytic in general and can decompose lignin and cellulose, and thus have significan.....»»
See the Southern Ring Nebula in 3D
Planetary nebula are some of nature's most stunning visual displays. The name is confusing since they're the remains of stars, not planets. But that doesn't detract from their status as objects of captivating beauty and intense scientific study......»»
How evolution has optimized the magnetic sensor in birds
Migratory birds are able to navigate and orientate with astonishing accuracy using various mechanisms, including a magnetic compass. A team led by biologists Dr. Corinna Langebrake and Prof. Dr. Miriam Liedvogel from the University of Oldenburg and t.....»»
Evolutionary biologists show that the color variants of female cuckoos are based on ancient mutations
Every cuckoo is an adopted child—raised by foster parents, into whose nest the cuckoo mother smuggled her egg. The cuckoo mother is aided in this subterfuge by her resemblance to a bird of prey. There are two variants of female cuckoos: a gray morp.....»»
The story of the first Alor people adapting to climate change 43,000 years ago
As humans, our greatest evolutionary advantage has always been our ability to adapt and innovate. When people first reached the expanded coastline of Southeast Asia around 65,000 years ago, and faced the sea crossings necessary to continue east into.....»»
Scientists use ancient DNA, historical context to unravel kinship, social practices of Avar society
A multidisciplinary research team led by scientists at the Max Planck Institute for Evolutionary Anthropology has combined ancient DNA data with a clear archaeological, anthropological and historical context to reconstruct the social dynamics of Avar.....»»
A key gene helps explain how the ability to glide has emerged over-and-over during marsupial evolution
People say "When pigs fly" to describe the impossible. But even if most mammals are landlubbers, the ability to glide or fly has evolved again and again during mammalian evolution, in species ranging from bats to flying squirrels. How did that come a.....»»
Enhanced CRISPR method enables stable insertion of large genes into the DNA of higher plants
Scientists at the Leibniz Institute of Plant Biochemistry (IPB) have succeeded for the first time in stably and precisely inserting large gene segments into the DNA of higher plants very efficiently. To do this, they optimized the gene-editing method.....»»
Study finds climate change is helping tropical fish invade Australian ocean water
A University of Adelaide study of shallow-water fish communities on rocky reefs in south-eastern Australia has found climate change is helping tropical fish species invade temperate Australian waters. The work is published in the Journal of Animal Ec.....»»
Researchers report on mechanisms of gene regulatory divergence between species
Closely related animal species can look physically different, but you might be surprised to learn that those differences can result not only from DNA sequence changes that alter proteins' structure or function, but also because changes in the DNA aff.....»»
Same species, different sizes: Rare evolution in action spotted in island bats
A University of Melbourne researcher has spotted a rare evolutionary phenomenon happening rapidly in real time in bats living in the Solomon Islands......»»
Astronomers discover largest stellar black hole in Milky Way: Study
Astronomers identified the largest stellar black hole yet discovered in the Milky Way, with a mass 33 times that of the Sun, according to a study published on Tuesday......»»
In Ecuadoran Amazon, butterflies provide a gauge of climate change
Biologists on a trail in the Ecuadoran Amazon hold their breath as they distribute a foul-smelling delicacy to lure butterflies, critical pollinators increasingly threatened by climate change......»»

Astronomers identified the largest stellar black hole yet discovered in the Milky Way, with a mass 33 times that of the Sun, according to a study published on Tuesday......»»
Uncovering key players in gene silencing: Insights into plant growth and human diseases
Monash University biologists have shed light on the intricate molecular mechanisms that are responsible for gene silencing induced by expanded repeats in an international study published today in Nature Plants......»»
Seeing is believing: Scientists reveal connectome of the fruit fly visual system
Janelia scientists and collaborators have reached another milestone in connectomics, unveiling a comprehensive wiring diagram of the fruit fly visual system. The work has been released on the pre-print server bioRxiv......»»
