These Gene-Edited Chickens Were Made to Resist Bird Flu
Avian influenza can wipe out entire poultry flocks. An early experiment with Crispr suggests that gene editing can protect chickens against infection......»»
AI deciphers new gene regulatory code in plants and makes accurate predictions for newly sequenced genomes
Genome sequencing technology provides thousands of new plant genomes annually. In agriculture, researchers merge this genomic information with observational data (measuring various plant traits) to identify correlations between genetic variants and c.....»»
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......»»
How worrying is bird flu"s jump to dairy cows? Here"s what experts say
Since 2022, a highly contagious strain of bird flu has spread across the U.S. at an unprecedented rate, resulting in the deaths of more than 90 million birds in commercial and backyard poultry flocks, plus thousands more in the wild......»»
More cows are being tested and tracked for bird flu. Here"s what that means
U.S. health and agriculture officials are ramping up testing and tracking of bird flu in dairy cows in an urgent effort to understand—and stop—the growing outbreak......»»
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.....»»
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.....»»
Fragments of bird flu virus genome found in pasteurized milk, FDA says
The test cannot tell if the virus is live. The FDA still assess milk supply as safe. Enlarge / Cows being milked (credit: Getty | Edwin Remsberg) The Food and Drug Administration on Tuesday announced that genetic fragmen.....»»
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.....»»
Concern grows as bird flu spreads further in US cows: 32 herds in 8 states
Experts say the US is not sharing as much data on the outbreak as it should. Enlarge / Greylag geese sit on a field and rest while a cow passes by in the background. (credit: Getty | Daniel Bockwoldt) Researchers aroun.....»»
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......»»
H5N1 strain of bird flu found in milk: WHO
The H5N1 bird flu virus strain has been detected in very high concentrations in raw milk from infected animals, the WHO said Friday, though how long the virus can survive in milk is unknown......»»
Scientists discover forests that may resist climate change
While it's common knowledge that mountaintops are colder than the valleys below, a new University of Vermont (UVM) study is flipping the script on what we know about forests and climate......»»
Bird flu in cattle: What are the concerns surrounding the newly emerging bovine H5N1 influenza virus?
The confirmed presence of bird flu in American dairy cattle in a March 25 report from the U.S. Department of Agriculture (USDA)—and a case in Texas where a human working with cattle was infected—has put Canadian public health experts on high aler.....»»
Team finds direct evidence of "itinerant breeding" in East Coast shorebird species
Migration and reproduction are two of the most demanding events in a bird's annual cycle, so much so that the vast majority of migratory birds separate the two tasks into different times of the year......»»
Researchers find babbling by zebra finch chicks is important step to memorizing songs
When babies learn to talk or birds learn to sing, the same principle applies: listen and then imitate. This is how the first babble becomes the first word or vocalization. Male zebra finch chicks initially memorize the song of an adult bird. Later, t.....»»
Cut light pollution and treat glass to help migrating birds, say researchers
Spring bird migration has begun. Under cover of darkness, 2.5–3.5 billion birds will fly northward to their breeding grounds in the United States and Canada. According to the Cornell Lab of Ornithology, now is one of the most important times of yea.....»»
Digital tools, including AI, alter consumer trust and purchasing decisions, says research
Colleen Harmeling, a Florida State University College of Business researcher, points to photo filters, overly edited photos and other distortions of user-generated content as impediments to consumer trust. In turn, they are potential barriers to the.....»»
Researchers discover previously unknown gene that indirectly promotes photosynthesis in blue-green algae
Cyanobacteria—also called blue-green algae—are known as the "plants of the ocean" because they carry out photosynthesis on a gigantic scale, produce oxygen and extract the greenhouse gas CO2 from the environment. However, to do this they need add.....»»
Newly sequenced genome reveals coffee"s prehistoric origin story, and its future under climate change
The key to growing coffee plants that can better resist climate change in the decades to come may lie in the ancient past......»»
