Generative AI models are encoding biases and negative stereotypes in their users      (via sciencedaily.com)     Original source 

In the space of a few months generative AI models, such as ChatGPT, Google's Bard and Midjourney, have been adopted by more and more people in a variety of professional and personal ways. But growing research is underlining that they are encoding biases and negative stereotypes in their users, as well as mass generating and spreading seemingly accurate but nonsensical information. Worryingly, marginalized groups are disproportionately affected by the fabrication of this nonsensical information.

Do hummingbirds drink alcohol? More often than you think      (via sciencedaily.com)     Original source 

Animals that eat fruit or sip nectar often ingest alcohol because naturally occurring yeasts turning sugar into ethanol. But how do animals feel about that? A new study details an experiment to determine whether hummingbirds are turned off by alcohol in sugar water. At 1% by volume, no. At 2% by volume, they consume much less. The implication is that hummingbirds have adjusted to small amounts of alcohol likely present in flowers and backyard feeders.

RSV is a serious heath threat, but the public knows little about it      (via sciencedaily.com)     Original source 

A new survey finds that the American public is ill-informed about RSV, unfamiliar with its most common symptoms, and more hesitant to recommend a vaccine against it to pregnant people than to older adults.

A roadmap for gene regulation in plants      (via sciencedaily.com)     Original source 

For the first time, researchers have developed a genome-scale way to map the regulatory role of transcription factors, proteins that play a key role in gene expression and determining a plant's physiological traits. Their work reveals unprecedented insights into gene regulatory networks and identifies a new library of DNA parts that can be used to optimize plants for bioenergy and agriculture.

Now, every biologist can use machine learning      (via sciencedaily.com)     Original source 

Scientists have built a new, comprehensive AutoML platform designed for biologists with little to no ML experience. New automated machine learning platform enables easy, all-in-one analysis, design, and interpretation of biological sequences with minimal coding. Their platform, called BioAutoMATED, can use sequences of nucleic acids, peptides, or glycans as input data, and its performance is comparable to other AutoML platforms while requiring minimal user input.

Worms use electricity to jump      (via sciencedaily.com)     Original source 

In nature, smaller animals often attach themselves to larger ones to 'hitch a ride' and save energy migrating large distances. Researchers show how microscopic Caenorhabditis elegans worms can use electric fields to 'jump' across Petri plates or onto insects, allowing them to glide through the air and attach themselves, for example, onto naturally charged bumblebee chauffeurs.

Drug-resistant fungi are thriving in even the most remote regions of Earth      (via sciencedaily.com)     Original source 

New research has found that a disease-causing fungus -- collected from one of the most remote regions in the world -- is resistant to a common antifungal medicine used to treat infections.

Scientists discover critical factors that determine the survival of airborne viruses      (via sciencedaily.com)     Original source 

Critical insights into why airborne viruses lose their infectivity have been uncovered. The findings reveal how cleaner air kills the virus significantly quicker and why opening a window may be more important than originally thought. The research could shape future mitigation strategies for new viruses.

Bridging traditional economics and econophysics      (via sciencedaily.com)     Original source 

How do asset markets work? Which stocks behave similarly? Economists, physicists, and mathematicians work intensively to draw a picture but need to learn what is happening outside their discipline. A new paper now builds a bridge.

A new tool to study complex genome interactions      (via sciencedaily.com)     Original source 

Genome Architecture Mapping captures complex, multi-way interactions in the genome. This is different than the workhorse technique of 3D genomics, which sees mostly two-way contacts, finds a new study.

New insights on bacteria that causes food poisoning      (via sciencedaily.com)     Original source 

A joint research group has clarified how pathogenic genes in some Providencia spp., which have gained attention as causative agents of food poisoning as well as enterohemorrhagic Escherichia coli. O157 and Salmonella, are transferred within bacterial cells. Their findings are expected to provide new insights into the identification of infection routes of Providencia spp. and the establishment of preventive methods for food poisoning.

How fungus farming ants keep their gardens healthy      (via sciencedaily.com)     Original source 

'Weed early and often' is the key to a productive garden. Interestingly, certain species of ants are also avid gardeners, a practice they've refined over 50 million years. They too weed their underground fungus gardens, but how they know what to weed out has been a mystery. Now, a multidisciplinary team of scientists report how ants distinguish the good fungus from the bad.

Genome editing used to create disease resistant rice      (via sciencedaily.com)     Original source 

Researchers have used the genome-editing tool CRISPR-Cas to create disease resistant rice plants, according to a new study. Small-scale field trials in China show that the newly created rice variety exhibited both high yields and resistance to the fungus that causes a serious disease called rice blast.

Close up on aging reveals how different cell types in the body age at different pace      (via sciencedaily.com)     Original source 

A team or researchers reports the first Aging Fly Cell Atlas (AFCA), a detailed characterization of the aging process in 163 distinct cell types in the laboratory fruit fly. Their in-depth analysis revealed that different cell types in the body age differently, each cell type following a process involving cell type-specific patterns. AFCA provides a valuable resource for researchers in the fruit fly and aging communities as a reference to study aging and age-related diseases and to evaluate the success of anti-aging strategies.
