New strategies against bone metastases from prostate cancer
- ScienceDaily
- 19/12/2 20:06
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...
Reflecting on photos helps young cancer survivors regain confidence
- ScienceDaily
- 19/12/2 20:06
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...

- ScienceDaily
- 19/12/2 19:57
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.
Sustaining roads with grape and agricultural waste
- ScienceDaily
- 19/12/2 19:57
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.
Cracking 60-year-old mystery of Sun's magnetic waves
- ScienceDaily
- 19/12/2 19:57
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.

The deadly superbugs lurking in more than nine in ten make-up bags
- ScienceDaily
- 19/12/2 19:57
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.
Cell-free synthetic biology comes of age
- ScienceDaily
- 19/12/2 19:57
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.
Missing link between soft surface adhesion and surface roughness
- ScienceDaily
- 19/12/2 19:57
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.
Why stress doesn't always cause depression
- ScienceDaily
- 19/12/2 19:56
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.
The neurobiological basis of gender dysphoria
- ScienceDaily
- 19/12/2 19:56
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.
Tiny woodlands are more important than previously thought
- ScienceDaily
- 19/12/2 18:46
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.
1940s blood samples reveal historical spread of malaria
- ScienceDaily
- 19/12/2 18:46
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.
Antarctic ice sheets could be at greater risk of melting than previously thought
- ScienceDaily
- 19/12/2 18:46
Antarctica is the largest reservoir of ice on Earth -- but new research suggests it could be at greater risk of melting than previously thought.
Antarctica's thinning ice shelves causing more ice to move from land into sea
- ScienceDaily
- 19/12/2 18:46
New study provides the first evidence that thinning ice shelves around Antarctica are causing more ice to move from the land into the sea.
Sweet potato uses a single odor to warn its neighbors of insect attack
- ScienceDaily
- 19/12/2 18:46
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...
A trick for taming terahertz transmissions
- ScienceDaily
- 19/12/2 18:46
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...
Protein defect leaves sperm chasing their tails
- ScienceDaily
- 19/12/2 18:46
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...
Deep learning identifies molecular patterns of cancer
- ScienceDaily

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.
This 'fix' for economic theory changes everything from gambles to Ponzi schemes
- ScienceDaily
- 19/12/2 17:30
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.
Breathing? Thank volcanoes, tectonics and bacteria
- ScienceDaily
- 19/12/2 17:30
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...

Monkeys inform group members about threats -- following principles of cooperation
- ScienceDaily
- 19/12/2 16:58
Humans are often faced with the choice of investing in the greater good or being selfish and letting others do the work. Animals that live in groups often encounter threats, and informing others could potentially save lives. Researchers show that wild sooty mangabeys, when facing dangerous vipers, do not just call out of fear or to warn their family, but will call when the information about the...
