A sperm whale that stranded and then died on a beach in Scotland had 100 kilograms of plastic in its stomach, including nets, cups, bags and other...
Facebook started testing a tool on Monday that lets users move their images more easily to other online services, starting with rival Google Photos, as it faces pressure from regulators to loosen its grip on...
Nancy Pelosi tells UN conference in Madrid that commitment is ‘iron-clad’The US will take action on greenhouse gases and engage with other countries on the climate emergency despite Donald Trump’s rejection of international cooperation, a delegation from the US Congress has told the UN climate conference in Madrid.Nancy Pelosi, the speaker of the House, struck a defiant stance on Monday,...
A study suggests a new approach, or, possibly two new approaches against prostate cancer bone metastases: While targeted therapies and anti-cancer immunotherapies have not been especially successful against primary prostate cancers, the study suggests that both these approaches may be effective against the bone metastases that grow from primary prostate cancers, and, in fact, the type of bone...
Young cancer survivors face unique medical and psychosocial challenges that can hinder their ability to move on mentally and socially, even years after their final treatment. Lingering feelings of isolation and loss can contribute to a lack of confidence and self-efficacy, or the sense that they will be able to handle whatever arises in the future. But new research suggests survivors who retell...
Scientists have directly demonstrated for the first time how laser beams modify the conditions of a plasma, addressing one of the challenges in the longstanding quest to achieve fusion.
The US spends $5 billion a year to repair damages to road infrastructure from winter snow and ice control operations and the use of traditional deicers. A team of researchers is developing a more sustainable solution using grape skins and other agricultural waste.
Scientists have discovered why the Sun's magnetic waves strengthen and grow as they emerge from its surface, which could help to solve the mystery of how the corona of the Sun maintains its multi-million degree temperatures.
Simulations show that halo currents can serve as a proxy for the total force produced by vertical disruptions.
The vast majority of in-use make-up products such as beauty blenders, mascara and lip gloss are contaminated with potentially life threatening superbugs, new research has revealed.
New research explores how cell-free gene expression stands to help the field of synthetic biology dramatically impact society, from the environment to medicine to education.
New research finds the missing link between soft surface adhesion and the roughness of the hard surface it touches. The key to this foundational discovery is a close look at the rough surface itself using an electron microscope.
Rats susceptible to anhedonia, a core symptom of depression, possess more serotonin neurons after being exposed to chronic stress, but the effect can be reversed through amygdala activation, according to new research in JNeurosci.
A new theory of gender dysphoria argues the symptoms of the condition are due to changes in network activity, rather than incorrect brain sex, according to new work.
Peter Lock, a former probation officer, and psychotherapist Tricia Scott on jail conditions that can do more harm than good to prisonersAs a retired probation officer who was involved in the delivery of training programmes for the Criminal Justice Act 2003, I would suggest that the inadequacy of sentencing in Usman Khan’s case was rooted in the manner in which imprisonment for public protection...
Small woodlands in farmland have more benefits for humans per area, compared to large forests according to a new study. The small woodlands, sometimes even smaller than a football field, can easily go unnoticed in agricultural landscapes. Yet, these small forest remnants can store more carbon in the topsoil layer, are more suitable for hunting activities and host fewer ticks than large forests.
DNA from 75-year old eradicated European malaria parasites uncovers the historical spread of one of the two most common forms of the disease, Plasmodium vivax, from Europe to the Americas during the colonial period, finds a new study.
Antarctica is the largest reservoir of ice on Earth -- but new research suggests it could be at greater risk of melting than previously thought.
New study provides the first evidence that thinning ice shelves around Antarctica are causing more ice to move from the land into the sea.
A single volatile substance can be sufficient to induce a defense response in sweet potatoes to herbivores. Researchers have identified this substance and shown that the mechanism is not only limited to the attacked plant itself but also alerts unaffected neighboring plants to defend themselves against attackers. This response is specific and not observed in every sweet potato cultivar. The...
Researchers have invented a wireless communication receiver that can operate in the terahertz frequency band. By increasing the sensitivity 10,000-fold, they achieved the fastest Researchers invent a new receiver for terahertz-frequency radiation -- by implementing coherent detection, they achieve record transmission rates -- this work may lead to much faster wireless data speeds using less...
Researchers have characterized a protein, called VSP, that keeps sperm swimming in straight lines. Deletion of the protein caused sperm to swim in circles, significantly reducing fertilization rates. VSP also controlled the influx of calcium ions into the flagellum, which is necessary for propulsion of the sperm towards the egg. The researchers hope that their discovery will aid in the development...
An artificial intelligence platform can analyze genomic data extremely quickly, picking out key patterns to classify different types of colorectal tumors and improve the drug discovery process. The deeper analysis shows some colorectal subtypes need to be reclassified.
The solutions to today’s puzzles and the results of the Xmas univocalic challengeEarlier today I set you a Christmas challenge (about which more below) and these three puzzles from the Mathigon advent calendar: Continue...
The Malagasy tree boa is under threat from poaching and fires.
The man who picked up a young coyote — that is now recovering at the Wildlife Haven Rehabilitation Centre — was "extremely surprised" when a co-worker pointed out that the driver had not hit a big dog like he originally...
Whether we decide to take out that insurance policy, buy Bitcoin, or switch jobs, many economic decisions boil down to a fundamental gamble about how to maximize our wealth over time. How we understand these decisions is the subject of a new perspective piece that aims to correct a foundational mistake in economic theory.
A new study suggests Earth's first burst of oxygen was added by a spate of volcanic eruptions brought about by tectonics. In addition to explaining the appearance of significant concentrations of oxygen in the Great Oxidation Event (GOE) 2.5 billion years ago, the theory also accounts for the Lomagundi Event, a puzzling shift in the ratio of carbon isotopes in carbonate minerals that followed the...
New research shows that the body's system for regulating iron is much more complex than originally thought -- and this has surprising implications in at least three human diseases.
Bacterial biofilms that develop around golden staph infections make treatment difficult and prolonged, but researchers have shown in laboratory work that the hybrid antibiotics they have developed can destroy staph biofilms.
Polycystic ovary syndrome is believed to affect about one in five women of reproductive age Daughters of women with polycystic ovary syndrome, a common disorder that can cause excessive body hair, acne and fertility problems, are five times more likely than the average woman to develop the condition, a major study has found.Researchers in Sweden examined the medical histories of nearly 30,000...
It’s bad enough that adults have made a climatological mess of the world. It’s worse that the mess is having a disproportionate impact on kids—who did nothing to create the problem, but are more susceptible to health issues caused by rising temperatures than adults are. Now, it appears, global warming is doing its damage even further down the human age spectrum. According to a...
Using an innovative microscopy method, scientists have revealed the structure of the microbial communities coating microplastic trash collected from a variety of ocean sites.
