How San Diego grew into a magnet for Nobel-quality talent in science
She lived in England during the age of Dickens, taught school in Illinois as America expanded west, wrote for a scrappy newspaper in Detroit after the Civil War, and spent her latter years in San Diego sharing a fortune.
Next-generation telescopes could detect the direct collapse of enormous black holes near the beginning of time
The first black holes to appear in the universe may have formed from the direct collapse of gas. When they collapsed, they released a flood of radiation, including radio waves. A new study has found that the next generation of massive radio telescopes may be able to detect these bursts, giving precious insights into a critical epoch in the history of the universe.
Study: Fish camouflage better without friends nearby
It's like a half-hearted dress up party: gobies don't camouflage completely when in groups, new research finds. Gobies change color to avoid detection by predators and do so faster and better when alone.
Long-term experiment shows warming slows microbes' growth
In a first-of-its-kind warming experiment, researchers at Northern Arizona University found that microbes growth rate decreased over 15 years of warming. The research, published this week in Global Change Biology, showed that under warmer climate conditions, growth decreased among all types of microbes in the community, and suggested that a loss of soil carbon may be responsible for the slowdown.
Exotic magnetic states in miniature dimensions
We are all used to the idea that simpler units in nature interact to form complex structures. Take, for example, the hierarchy of life, where atoms combine to form molecules, molecules combine to form cells, cells combine to form tissues, and so on, ultimately leading to the formation of complex organisms such as humans. In the quantum world, however, this process may play in reverse, where...
No to the re-approval of glyphosate – Large aerial dispersal confirmed
The EU authorities' assumption that glyphosate does not spread through the air has been disproven. The results of the German study "Pesticide pollution of the air" prove that glyphosate and dozens of other pesticides are traveling through the air for miles into national parks and cities. The analysis was initially published in 2019 and has now been peer-reviewed by independent scientists and...
Serendipitous discovery leads to a new understanding of how cells multitask
Quantitative Biosciences Institute (QBI) researchers at UC San Francisco have discovered a new paradigm for how fundamental biological switches, proteins that can be turned on and off to control processes like cell differentiation, cell growth, and transport within a cell, are regulated at the molecular level, specifically by molecules binding at newly discovered sites far away from the main...
Unique underpinnings revealed for stomach's acid pump
Nagoya University researchers and colleagues have improved understanding of the molecular mechanisms of a key protein that makes the stomach acidic. Their findings, published in the journal Nature Communications, could lead to better drugs for stomach ulcers and shed light on the functions of similar proteins across the human body."This gastric protein pumps in acidic ions to fortify our stomach,...
Sustainable farming: There's no one solution
Sustainable agriculture will not be achieved by one universal solution. A meta-analysis by the University of Basel shows that the current focus on no-till farming does not achieve the desired results. A sustainable system of agriculture must be designed for local needs and in dialog with local farmers.
How your firm's Tweets affect its value—both temporarily and permanently
Researchers from University of Edinburgh and University of Maryland published a new paper in the Journal of Marketing that examines the impact of firm-generated social media content on firm stock price in real time.
Death threats, trolling common for scientists who speak to media about COVID
(HealthDay)—Doctors who discuss COVID-19 in the media frequently face abuse and harassment, including threats of death or violence, a new report reveals.
Americans are eating more ultra-processed foods

Consumption of ultra-processed foods has increased over the past two decades across nearly all segments of the U.S. population, according to a new study.
Scientists map brain circuit that drives activity in fertile females
- ScienceDaily
- 21/10/14 16:20
Scientists have known for a century that female animals become more active just as they are about to ovulate, a behavior that evolved to enhance their chances of mating when they are fertile.
Lone changer: Fish camouflage better without friends nearby
- ScienceDaily
- 21/10/14 16:20
While gobies aren't the only fish with camouflage abilities, new research shows that their colour change is influenced by their social context: they transform faster and better when alone. This is likely an adaptive, stress response to perceived threat from predators - with possible application to other camouflaging species.

A cell-based influenza vaccine has effectively provided protection against the flu in children and adolescents, according to a new study.
Data continues to show that American’s need at least 5 hours per week of physical activity to prevent some cancers
- ScienceDaily
- 21/10/14 16:20
A new report finds more than 46,000 cancer cases annually in the United States could be prevented if Americans met the 5 hours per week of moderate-intensity recommended physical activity guidelines.
Bone-loss discovery points to new treatment for osteoporosis

Sense of smell is our most rapid warning system
- ScienceDaily
- 21/10/14 16:01
The ability to detect and react to the smell of a potential threat is a precondition of our and other mammals' survival. Using a novel technique, researchers have been able to study what happens in the brain when the central nervous system judges a smell to represent danger. The study indicates that negative smells associated with unpleasantness or unease are processed earlier than positive smells...
