The hemispheres are not equal: How the brain is not symmetrical
- ScienceDaily
- 22/9/15 18:37
Although the brain is divided into two halves, it is not exactly a mirror image. Some functions are processed more on the left side, others more on the right. Scientists have now discovered heritable underpinnings of brain asymmetry and how much we share with monkeys.

- ScienceDaily
- 22/9/15 18:37
Thanks to two novel tools, the traditionally difficult surgery to create a replacement ear from a patient's rib cartilage may soon be done faster, more simply and accurately.
Scientists discover novel mechanism that causes rare brain disease
- ScienceDaily
- 22/9/15 18:37
A rare but potentially debilitating brain disorder finally has a definitive cause, thanks to research teams working on opposite sides of the globe. A mutation in the gene that manages the transportation out of cells of zinc, an essential dietary micronutrient, is responsible for the disorder, called hypomyelinating leukodystrophy.
How songbirds' striking colors put them at risk
- ScienceDaily
- 22/9/15 18:37
Bright, uniquely colored songbirds are at higher risk of extinction and more likely to be traded as pets. Researchers also predict that almost 500 additional bird species, most of them living in the tropics, are at risk of future trade based on their unique and desirable coloration.
Discovery of extinct prehistoric reptile that lived among dinosaurs
- ScienceDaily
- 22/9/15 18:37
Researchers have discovered a new extinct species of lizard-like reptile that belongs to the same ancient lineage as New Zealand's living tuatara. A team of scientists describe the new species Opisthiamimus gregori, which once inhabited Jurassic North America about 150 million years ago alongside dinosaurs like Stegosaurus and Allosaurus. In life, this prehistoric reptile would have been about 16...
'Digital mask' could protect patients' privacy in medical records
- ScienceDaily
- 22/9/15 18:36
Scientists have created a 'digital mask' that will allow facial images to be stored in medical records while preventing potentially sensitive personal biometric information from being extracted and shared.
Astronomers risk misinterpreting planetary signals in James Webb data
- ScienceDaily
- 22/9/15 18:36
Astronomers risk misinterpreting planetary signals in James Webb data if models to interpret the data don't improve, a new study finds.
New tool overcomes major hurdle in clinical AI design
- ScienceDaily
- 22/9/15 18:36
Most clinical AI models rely on laborious human annotation to make accurate diagnoses. A new AI model overcomes this hurdle.
COVID-19 vaccination rates at NYC schools varied significantly by race/ethnicity and borough
- ScienceDaily
- 22/9/15 18:36
For the more than one million children attending New York City public schools, the likelihood of receiving COVID-19 vaccines depended on their race and ethnicity, and the borough in which they live.
Immunotherapy reduces lung and liver fibrosis in mice
- ScienceDaily
- 22/9/15 18:36
Chronic diseases often lead to fibrosis, a condition in which organ tissue suffers from excessive scarring. Researchers have now developed an immunotherapy that specifically targets the cause -- activated fibroblasts -- while leaving normal connective tissue cells unharmed. If this approach is also found to work in humans, it could lead to an effective treatment for fibrosis.
When microbiomes collide
- ScienceDaily
- 22/9/15 18:36
Researchers used data from over 300 human fecal microbiota transplants to understand what happens when two gut microbiomes mix together. The answer could inform better therapeutic strategies for gut disorders and provide a richer understanding of how microbes behave and interact in complex natural ecosystems.
T cells use force to destroy cancer cells
- ScienceDaily
- 22/9/15 18:36
New research reveals the mechanical processes used by T cells to kill cancer cells more efficiently.
New signal for triggering human immune response
- ScienceDaily
- 22/9/15 18:36
Researchers found that disruption of a cellular structure, known as the actin cytoskeleton, is a 'priming signal' for the body to respond to a virus. These findings potentially lay the groundwork for development of new anti-viral vaccines and treatments.
Team develops method to identify future SARS-CoV-2 mutations that could affect rapid antigen test performance
- ScienceDaily
- 22/9/15 18:36
Researchers have shown that commercially available rapid antigen tests can detect past and present variants of concern and have identified potential mutations that may impact test performance in the future.
molecular origin of the genetic disease cystinosis revealed
- ScienceDaily
- 22/9/15 18:36
The rare genetic disease cystinosis is caused by mutations in the gene for a protein called cystinosin. A team of scientists has now solved the structure of cystinosin and determined how mutations interfere with its normal function, providing insights into the underlying mechanisms and suggesting a way to develop new treatments for the disease.
Mind over matter: Helping amputees regain their independence
- ScienceDaily
- 22/9/15 18:36
New research says adopting a new, attentional mindset in the field of physical therapy can help amputees live with prosthesis more naturally.
How to keep kids curious: Five questions answered
Kids are naturally curious. But various forces in the environment can dampen their curiosity over time. Can anything be done to keep kids' curiosity alive? For answers to this question, The Conversation U.S. turned to Perry Zurn, a philosophy professor at American University and author of three books on curiosity, including "Curious Minds: The Power of Connection," which was released in September...
Inhibitor of lipid kinase PI3KC2a identified as potential new treatment of thrombosis
The lipid kinase PI3KC2a is a potential pharmacological target for the treatment of thrombosis and, possibly, cancer. Researchers from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) have now identified a potent inhibitor of its activity that serves as a lead for further drug development.
Thousands of Australian lives could be lost without rapid adoption of electric vehicles
New Swinburne University of Technology research reveals that Australia risks losing 24,000 lives by 2042 from transport-induced air pollution, and $148 billion in net benefits, if electric vehicles are not rapidly adopted.
Solvent effect on film formation and device performance for 2D Dion-Jacobson perovskite solar cells
Quasi two-dimensional perovskite solar cells (2D PSCs) have received much attention recently due to their unique optoelectronic properties and excellent device stability. Among 2D perovskite, 2D Dion-Jacobson (DJ) perovskite has closer interlayer distance and does not rely on van der Waals interaction between adjacent spacer cations, which can weaken dielectric confinement effect while maintaining...
Disadvantaged population groups perceive their capabilities to promote individual health and well-being as weak
Young people not in education, employment or training, long-term unemployed, people with refugee backgrounds, and older people living alone and at risk of exclusion perceive their capabilities to promote their individual health and well-being as weak. A new study shows that these people also perceived their quality of life to be weaker than the Finnish population on average.

The rare genetic disease cystinosis is caused by mutations in the gene for a protein called cystinosin. A team of scientists has now solved the structure of cystinosin and determined how mutations interfere with its normal function, providing insights into the underlying mechanisms and suggesting a way to develop new treatments for the disease.
Fireball in night sky likely to have been space junk
The "shooting star" was reported by hundred of people across Scotland and Northern Ireland .
T cells use force to destroy cancer cells
As a part of our immune defenses, cytotoxic T cells—or killer T cells—seek out and destroy cells that are infected or cancerous. This process is essential for the body's defense against diseases.
