Astronomy has long been dominated by expert amateurs but with geospatial data everywhere, thanks to widely available internet and smartphones, it is not just that directions that were once only available in a paper map are now updated on your phone in real time to account for traffic.
It is changing the relationships of science also. Crowdsourced scientific data will go from obscure folding protein folding of 15 years ago to relevance everywhere.
That evolution will continue to be driven by how the data is gathered.

sb admin | Mon, 01/29/2024 - 14:18Over the last few years, low-level red light (LLRL) therapy has become popular to control myopia, or nearsightedness, especially in children. In LLRL therapy, children are instructed to look into a red light-emitting instrument for three minutes, twice a day, five days a week, for the duration of the treatment period, which could last years.
Studies reported the treatment as effective and responsible for significant reduction in myopia progression and it is already being used to address myopia in over 100,000 pediatric patients.
Despite passing clinical trials it's not safe in all…
sb admin | Thu, 01/20/2022 - 20:17Despite claims of anti-vaccine activists no different than groups that used to claim vaccines cause autism, COVID-19 vaccines do not impact fecundability—the probability of conception per menstrual cycle—in female or male partners who received the Pfizer-BioNTech, Moderna, or Johnson & Johnson vaccines.
The prospective study instead indicates that COVID-19 infection among males may temporarily reduce fertility— an outcome that could be avoidable through vaccination.
Lead author Dr. Amelia Wesselink, epidemiologist at Boston University School of Public Health, and colleagues analyzed…

The number of fireworks being lit off at night is out of control this year.
While people often light off fireworks close to the Fourth of July, this year fireworks have been lit in large numbers starting weeks earlier. New York City had a 4,000% increase in fireworks complaints in the first two weeks of June compared with last year. This prompted Mayor Bill de Blasio to vow a crackdown on…
Social distancing due to the SARS-CoV-2 virus and the threat of COVID-19 has meant online communication is more popular than ever, with even casual parenting groups discovering the previous enterprise video conferencing tool Zoom.
But how will that affect communications? Have you ever met someone who is stiff in person but great on camera or the other way around? Neuroscientists study brain and…
Almost 2 million Americans have age-related macular degeneration (AMD), where the cells in the retina, which is the layer of tissue in the back of the eye, break down, causing central vision to become blurry. Over time, 100,000 of those will become blind.
An international team of scientists has identified a protein, FHR4, which is strongly linked to AMD when its levels are raised in the blood. …

(Inside Science) -- The fork-tailed flycatcher whistles with its wings in two different accents, potentially more evidence this bird is splitting into two species, a new study finds.
Birds are known for the songs they can sing, but dozens of species also use their feathers to generate sounds. For instance, peacocks can rattle their quills together, and the crested pigeon's wings whistle when…
It's not infrequently that, whenever I complain about the increasing infiltration of quackery and pseudoscience into medicine, I sometimes lament that skeptics and supporters of science-based medicine are massively outgunned, because we are. Thus, we have the continued growth of what I like to refer to as "quackademic medicine," the infiltration of pseudoscience into medical academia in the form…
I've caught a fair amount of flak over my opposition to so-called "right-to-try" laws. Right-to-try laws have proliferated throughout the US like so much kudzu over the last three and a half years, to the point where 37 states now have some version of these profoundly anti-patient laws on the books. At the federal level, three weeks ago the Senate passed a federal version of right-to-try, with…

'The uplift of the Tibetan Plateau' is invoked to explain various phenomena, from monsoon dynamics to biodiversity evolution and everything in between. It's not accurate, finds a new paper.
The orogeny of the Tibetan region (Tibet, The Himalaya and the Hengduan Mountains) dates back approximately 200 million years, long before the arrival of India, and was the product of earlier Gondwanan…
The International Union for the Conservation of Nature, a coalition of activist groups which recently charged that climate change is contributing to exploitation of women, is now arguing that various factors are causing 2,000 species of fireflies to go extinct.
They came to the conclusion by surveying affiliates to ask them what is driving fireflies to extinction.
According to survey…
Insects scuttle, chew and fly through the world around us. Humans rely on them to pollinate plants, prey on insects that we don’t get along with, and to be movers and shakers for Earth’s ecosystems. It’s hard to imagine a world without insects.
That’s why news reports in recent months warning of an “insect apocalypse” sparked widespread alarm. These articles, which were based on long-term insect…

"I was born not knowing and have had only a little time to change that here and there." -Richard Feynman
Scientists have long had a reputation for being uptight, serious, and even killjoy personalities. But 50+ years ago, Richard Feynman was forcing everyone who felt that way to challenge their assumptions. With his brash attitude and fun-seeking personality, Feynman seemingly was most at home…

In an episode filled with Vulcan mindmelds, Klingon treachery, a spectacular nebula, themes of racial purity, and PTSD, you’d think all the ingredients were there for a spectacular episode of Star Trek: Discovery. Instead, describing it as a hot mess would be overly generous…

Well, the cat's out of the bag. A little over a week ago, Scienceblogs announced to us writers that they no longer had the funds to keep the site operational, and so they would be shutting down. They asked us to keep quiet about this, people didn't and now you know. As of the end of this month, there will be no new…

Picture this: it’s April 2020, you’re between Zoom meetings, and scrolling through your social media newsfeed. Headlines like “Death toll continues to rise”, “COVID-19 may cause long-term health implications” and “Health-care systems overwhelmed” flash across your screen. Your mood takes a dive, but you can’t stop scrolling.
If this scenario rings true for you, you’re not alone. Research shows…
Breastfeeding can play an especially important role in early-life nutrition. It can benefit children’s future school performance and economic prospects in later life, as well as the mother’s health.
Health authorities across the world endorse the World Health Organization’s (WHO) recommendation that newborns should where possible exclusively breastfeed from the first hour of life until six…
The proliferation of fake news about the COVID-19 pandemic has been labelled a dangerous “infodemic”. Fake news spreads faster and more easily today through the internet, social media and instant messaging. These messages may contain useless, incorrect or even harmful information and advice, which can hamper the public health response and add to social disorder and division.
Confusingly some…

Sudden oak death, caused by the pathogen Phythophthora ramorum, is one of the most ecologically devastating forest diseases in North America, responsible for the deaths of millions of oaks and tanoaks along the coast.
Science to the rescue? After the success of genetically modified organisms in things like insulin and food, a recent trend is Genetically Rescued Organisms. These GROs would use…
Imagine trying to cope with a pandemic like COVID-19 in a world where microscopic life was unknown. Prior to the 17th century, people were limited by what they could see with their own two eyes. But then a Dutch cloth merchant changed everything.
His name was Antonie van Leeuwenhoek, and he lived from 1632 to 1723. Although untrained in science, Leeuwenhoek became the greatest lens-maker of his…
With people confined to their homes, there is more interest in home-baked bread than ever before. And that means a lot of people are making friends with yeast for the first time. I am a professor of hospitality management and a former chef, and I teach in my university’s fermentation science program.
As friends and colleagues struggle for success in using yeast in their baking – and occasionally…

Has your doctor recommended you go for regular jogs in the park, countryside walks, community food growing sessions, or some other nature-based activity? These so-called “green prescriptions” are typically given alongside conventional therapies and have existed in various forms for a number of years.
In recognition of the potential health benefits of green prescriptions, the UK government has…

In the Yangtze Delta, about 160 kilometres southwest of Shanghai, the archeological ruins of Liangzhu City are located. There, a highly advanced culture blossomed about 5,300 years ago, thanks to the engineering of large hydraulic structures.
The walled city had a complex system of navigable canals, dams and water reservoirs. This system made it possible to cultivate very large agricultural…
A new estimate using sheet modeling finds that Greenland's rate of ice loss this century could outpace that of any century over the past 12,000 years, when the last Ice Age ended.
Scientists used reconstructions of ancient climate to drive the model, and validated the model against real-world measurements of the ice sheet's contemporary and ancient size.
The study brought together climate…
As surprising as it may sound, no one really knows what an electron is, and it is this fundamental question that has been the driving force for much of modern physics and eventually led to the development of quantum field theory.
To answer the question “What is an electron?”, you would think the first step would be to observe it. However, that is easier said than done. Electrons are simply too…

“I am looking at the future with concern, but with good hope.” –Albert Schweitzer
Every so often, the argument comes up that science is expendable. That we’re simply investing too much of our resources — too much public money — into an endeavor with no short-term benefits. Meanwhile, there’s suffering of all kinds, from poverty to disease to war to natural disasters, plaguing humanity all across…
A man who was not even known as a gun collector amassed an arsenal that all experts agree included illegal fully automatic weapons. He carried out an act of carnage, alone and using only those weapons, that exceeded in casualty count almost every military battle fought in recent decades by American troops, and that equaled or surpassed all but a very small number of terrorist attacks.
He shot…
Two years ago, I wrote about a study that demonstrated how the antivaccine movement had learned to use Twitter to amplify their antiscience message. At the time, I noted how in 2014, when the whole "CDC whistleblower" conspiracy theory was first hatched, antivaxers were so bad at Twitter, so obvious, so naive. The Tweeted inane claims at government officials, scientists, legislators, and whoever…

Scientists have used an unnatural amino acid and a catalytic copper complex to create a new, artificial enzyme.
Enzymes are natural catalysts that operate under mild conditions. This makes them an attractive alternative for industrial chemical catalysis, which may require high temperature and pressure and toxic solvents or metals. However, not all chemical reactions can be catalyzed by natural…
DNA evidence often isn’t as watertight as many people think. Sensitive techniques developed over the past 20 years mean that police can now detect minute traces of DNA at a crime scene or on a piece of evidence. But traces from a perpetrator are often mixed with those from many other people that have been transferred to the sample site, for example via a handshake. And this problem has led to…
