Pink pigeons in Mauritius made a remarkable comeback from near-extinction, but are still losing genetic diversity
In the 1980s there were just ten or so pink pigeons left in the wild. Known to scientists as Nesoenas mayeri, the species is found only on Mauritius, the Indian Ocean island that was once home to the dodo. Like the dodo, the pink pigeon made an easy.....»»
Evo—an AI-based model for deciphering and designing genetic sequences
Computer scientists, bioengineers and AI specialists from the Arc Institute and Stanford University have developed an AI-based model capable of decoding and designing genetic sequences. In their paper published in the journal Science, the group descr.....»»
Troubled waters: How to stop Australia"s freshwater fish species from going extinct
Three-quarters of Australia's freshwater fish species are found nowhere else on the planet. This makes us the sole custodians of remarkable creatures such as the ornate rainbowfish, the ancient Australian lungfish and the magnificently named longnose.....»»
One or many? Exploring the population groups of the Antarctic blue whale using historical mark-recovery data
Hunted nearly to extinction during 20th century whaling, the Antarctic blue whale, the world's largest animal, went from a population size of roughly 200,000 to little more than 300. The most recent estimate in 2004 put Antarctic blue whales at less.....»»

Using genetic code expansion to study membrane proteins
Over the years, chemical biology methods have made an important contribution to the study of integral membrane proteins. A key modern approach is genetic code expansion (GCE), which makes it possible to modify proteins directly in living cells to giv.....»»
Poor teacher training partly to blame for stalled engineering diversity goals
Diversifying the science, technology, engineering and math fields has long been a top priority of many universities and tech companies. It's also a goal of the National Science Foundation, the biggest funder of university-led research and development.....»»
Q&A: Holobiont biology, a new concept for exploring how microbiome shapes evolution of visible life
Microorganisms—bacteria, viruses and other tiny life forms—may drive biological variation in visible life as much, if not more, than genetic mutations, creating new lineages and even new species of animals and plants, according to Seth Bordenstei.....»»
Valencia floods: How to prevent a natural disaster from becoming a public health crisis
On 29 October, the unthinkable happened to thousands of people in the province of Valencia—in a matter of minutes, they went from going about their daily lives to being submerged or swept away by floodwaters, with many losing everything they own. A.....»»
Social media can turn household chores into profit—but are gender stereotypes making a comeback?
A study reveals a surprising transformation: as social media turns everyday household chores into profitable ventures, it may also be bringing back outdated gender stereotypes. Published in the Journal of Marketing Management, the research explores h.....»»
Using CRISPR to decipher whether gene variants lead to cancer
In recent years, scientists have created a range of new methods based on CRISPR-Cas technology for precisely editing the genetic material of living organisms. One application is in cell therapy: A patient's immune cells can be specifically reprogramm.....»»
One-step, high-speed, thermal-electric aerosol printing of piezoelectric bio-organic films
Amidst the ongoing surge in demand for bio-MEMS, wearable/implantable electronics and bio-tissue therapeutics, the pursuit of piezoelectric biomaterials has become a priority, thanks to their remarkable electromechanical properties, biocompatibility,.....»»
People do care about extinct species, but not for long—new study
Lonesome George was discovered motionless in his enclosure, one morning in June 2012. Overnight, George had taken not only his final breath but the final breath of his entire species, the Pinta Island tortoise, as it faded into extinction......»»

Geologists rewrite textbooks with new insights from Cambrian rocks of Grand Canyon
Since soon after our planet formed, Earth's 4.6 billion-year-long history was dominated by single-celled life. Something dramatic happened about 500 million years ago called the Cambrian "explosion," during which an incredible diversity of life forms.....»»
Researchers discover genetic reason for the red, yellow and orange bills of Australian finches
What gives an Australian finch its brilliantly colored red, yellow or orange bill? A major new study has uncovered the genetic switches controlling these distinctive colors, revealing a key piece in the puzzle of how animals develop their coloration......»»
Biologists discover how plants evolved multiple ways to override genetic instructions
Biologists at Washington University in St. Louis have discovered the origin of a curious duplication that gives plants multiple ways to override instructions that are coded into their DNA. This research could help scientists exploit a plant's existin.....»»
Genetic repair via CRISPR can inadvertently introduce other defects, researchers show
The CRISPR molecular scissors have the potential to revolutionize the treatment of genetic diseases. This is because they can be used to correct specific defective sections of the genome. Unfortunately, however, there is a catch: under certain condit.....»»
Testing thousands of RNA enzymes helps find first "twister ribozyme" in mammals
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, lik.....»»
