Male beetles neglect their genomes when competing for females
Male beetles face a trade-off between competing with other males for mating opportunities and repairing damage to their sperm DNA, according to a study published April 4 in the open access journal PLOS Biology by Mareike Koppik from Uppsala Universit.....»»
How the Lincoln Nautilus surprisingly won me over with its ride, huge screen
How I stopped worrying and learned to love the big screen. Enlarge / In the past, car companies engaged in "horsepower wars." Now it seems they're competing in a screen size war. (credit: Jonathan Gitlin) It's important.....»»
Phage viruses, used to treat antibiotic resistance, gain advantage by cutting off competitors" reproduction ability
Curious bits of DNA tucked inside genomes across all kingdoms of life historically have been disregarded since they don't seem to have a role to play in the competition for survival, or so researchers thought......»»
A 4,500-year-old collective tomb in France reveals final stage in formation of the "European genome"
High-resolution analysis of the genomes of individuals buried in a 4,500-year-old collective tomb at Bréviandes-les-Pointes, near the French town of Troyes, has revealed a surprising story with far-reaching implications. As detailed in an article in.....»»
A pregnant stingray with no male companion now has a "reproductive disease," aquarium says
A North Carolina aquarium that said it had a pregnant stingray with no male companion now says the fish has a rare reproductive disease......»»
Q&A: How to make sustainable products faster with artificial intelligence and automation
By modifying the genomes of plants and microorganisms, synthetic biologists can design biological systems that meet a specification, such as producing valuable chemical compounds, making bacteria sensitive to light, or programming bacterial cells to.....»»
Study reveals maintenance of male-related genes after loss of males in stick insects
Traits are often lost during evolution, either because they are no longer beneficial or because they are too costly to maintain. When this happens, it is generally believed that the genes underlying the trait will eventually degrade as well, making i.....»»
Animals self-medicate with plants—a behavior people have observed and emulated for millennia
When a wild orangutan in Sumatra recently suffered a facial wound, apparently after fighting with another male, he did something that caught the attention of the scientists observing him......»»

New findings on fertility: Sperm can adapt to sexually transmitted microbes
Researchers from Dresden University of Technology (TUD) and the University of Sheffield have discovered that male fertility can adapt to microbes. These findings shed new light on the importance of sperm ecology and might have significant implication.....»»
Study shows sexual parasitism helped anglerfish invade the deep sea during a time of global warming
Members of the vertebrate group including anglerfish are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate. Now, researchers reporting in the journal Current B.....»»
Bigger is better: Male proboscis monkeys" enhanced noses evolved to attract mates, says study

Research improves multiplex mutagenesis to increase experimental efficiency in plant genome editing
CRISPR/Cas9 remains the most powerful tool to generate mutations in plant genomes. Studying the various combinations of mutations has significantly increased the scale of experimental setups, necessitating more space to grow numerous plants......»»
AI model accurately predicts male fruit flies" courtship behavior in response to sight of a female
We've been told, "The eyes are the window to the soul." Well, windows work two ways. Our eyes are also our windows to the world. What we see and how we see it help determine how we move through the world. In other words, our vision helps guide our ac.....»»

New research suggests diverse headgear in hoofed mammals evolved from common ancestor
From the small ossicones on a giraffe to the gigantic antlers of a male moose—which can grow as wide as a car—the headgear of ruminant hooved mammals is extremely diverse, and new research suggests that despite the physical differences, fundament.....»»
How to watch Champions League soccer in the U.S. in 2024

A penguin with an unconventional call inspires researchers to change how they study penguins
An emperor penguin's sex determines the nature of their courtship call—male vocalizations are composed of long, slow bursts with lower frequency tones than the female version. But calls of SeaWorld San Diego male penguin E-79 caught the attention o.....»»
Tiger beetles fight off bat attacks with ultrasonic mimicry
Bats, as the main predator of night-flying insects, create a selective pressure that has led many of their prey to evolve an early warning system of sorts: ears uniquely tuned to high-frequency bat echolocation. To date, scientists have found at leas.....»»

Chinese fruit fly genomes reveal global migrations, repeated evolution
Fruit flies (Drosophila melanogaster), which humans have inadvertently spread around the globe, arrived in China roughly 4,000 years ago, according to a new population genomics study that adds to our understanding of the insect's global migration, de.....»»
