More than meows: How bacteria help cats communicate
Many mammals, from domestic cats and dogs to giant pandas, use scent to communicate with each other. A new study from the University of California, Davis shows how domestic cats send signals to each other using odors derived from families of bacteria.....»»
Red squirrels are very flexible in shifting their daily routines to avoid urban threats, researchers find
Scientific investigations before and during the COVID-19 lockdown in Berlin in 2020 show that urban red squirrels are extremely flexible in adjusting their diurnal activities to the presence of humans, domestic dogs, domestic cats, and predators such.....»»
Engineering nature"s blueprint: Dendron-based assemblies for chlorophyll"s materials
Researchers often look to photosynthesis—a process that turns sunlight into chemical energy in plants and bacteria—as a model for innovation. Photosynthesis is in turn linked to chlorophyll pigments, tiny green molecules that play a key role in h.....»»
Scientists develop culture system to unlock secrets of the skin microbiome
The human skin is home to a wide variety of bacteria. The composition of the community of bacteria—called the "skin microbiota"—has serious implications for skin health. A healthy balance between different species of bacteria on the skin often tr.....»»
Superior photosynthesis abilities of some plants could hold key to climate-resilient crops
More than 3 billion years ago, on an Earth entirely covered with water, photosynthesis first evolved in ancient bacteria. In the following millions of years, those bacteria evolved into plants, optimizing themselves along the way for various environm.....»»
Engineered antibiotic D22 shows promise against drug-resistant bacteria
Antibacterial drugs are important for treating infections. But increasingly, bacterial resistance to current drugs—so they don't work well, or even at all—means new ones are urgently needed......»»
Flies carry bacteria, and some are resistant to antibiotics—evidence from three South African hospices
Houseflies live close to humans and domesticated animals and because they are so mobile they can easily spread bacteria that make people sick......»»
With new imaging approach, scientists closely analyze microbial adhesive interactions
Scientists have identified many types of bacteria in the mouth, but many problems remain in understanding how they work with one another. One of the problems is that microbes assemble themselves into densely packed multi-species biofilms. Their densi.....»»
First successful synthesis of elusive antibiotic compounds since their discovery 50 years ago
Back in 1974, German researchers discovered peculiar chemical compounds, present as red pigments in soil bacteria from a volcanic crater. These biomolecules, which came to be known as naphthocyclinones, are representative of a family of antibiotics w.....»»
Study challenges assumptions about how tuberculosis bacteria grow
The rod-shaped tuberculosis (TB) bacterium, which the World Health Organization has once again ranked as the top infectious disease killer globally, is the first single-celled organism ever observed to maintain a consistent growth rate throughout its.....»»
Antarctic bacteria show promise as biocontrol agents for combating banana wilt
A recent study conducted by scientists at ESPOL has unveiled the biotechnological potential of microorganisms from Antarctica. In this remote continent, where life thrives under extreme conditions, researchers isolated 77 microbial strains from 162 c.....»»
Scientists propose drug-free method to combat antibiotic-resistant bacteria
Recent estimates indicate that deadly antibiotic-resistant infections will rapidly escalate over the next quarter century. More than 1 million people died from drug-resistant infections each year from 1990 to 2021, a recent study reported, with new p.....»»
Curly-Tailed Cats Communicate with an ‘Accent’
A genetic mutation makes some cats’ tail curl over their back, giving them something akin to an accent when they communicate with other kitties.....»»
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.....»»
Saturday Citations: Color vision created demand for colorful animals; observing black hole light echoes; deadlines!
This week, researchers hypothesized that human culture is distinguished from cultures of other species like whales by unique open-endedness—the ability to communicate and understand an infinite number of possibilities. An ancient unicellular organi.....»»
Bacteria discovery could accelerate mosquito control schemes
Mosquito larvae grow faster if they're exposed to particular bacteria, according to a new study that could help global health programs......»»
Handling the hype: Researcher seeks to improve science communication
Being a scientist has its challenges. Knowing how to communicate your scientific research in a socially responsible manner can be even more difficult. Thankfully, one researcher at Michigan State University and colleagues at several other universitie.....»»
A physicist and his cat "reveal" the equation of cat motion
In the social media age, there is little doubt about who is the star of the animal kingdom. Cats rule the screens just as their cousins, the lions, rule the savanna. Thanks to Erwin Schrödinger, this feline also has a place of honor in the history o.....»»

Fungi may not think, but they can communicate
Fungi form distinct networks depending on how food sources are arranged. Fungi can be enigmatic organisms. Mushrooms or other structures may be visible above the soil, but beneath.....»»
Human histones show promise in fighting bacterial infections
Antibiotics have saved millions of lives from infectious diseases and are considered one of the most important discoveries of the 20th century. However, as the use (and abuse) of antibiotics has increased over the years, many bacteria have developed.....»»
