New treatment triggers self-destruction of pancreatic cancer cells
A new Tel Aviv University study finds that a small molecule has the ability to induce the self-destruction of pancreatic cancer cells. The research holds great potential for the development of a new effective therapy to treat this aggressive cancer in humans.
NIH study reports more than half of US office-based physicians recommend CHA
A new study has shown that more than half (53.1%) of office-based physicians in the US, across specialty areas, recommended at least one complementary health approach (CHA) to their patients during the previous 12 months, with female physicians (63.2%) more likely to recommend a CHA than male physicians (49.3%).
novel bednet design improves safety, affordability and lethality to resistant mosquitoes
Researchers from LSTM have designed a new bednet that can kill mosquitoes more efficiently than existing nets, in a way that increases the choice of insecticide used, while minimising risk to the person inside the bednet.
Oat pathogen defence discovery marks an important milestone
Researchers have identified the critical last pieces of a genetic defense system that gives oats resistance to soil pathogens.
One in two homeless people may have experienced a head injury in their lifetime
People who are homeless experience a disproportionately high lifetime prevalence of traumatic brain injury (TBI), according to a new UBC-led study published today in The Lancet Public Health.
Percentage of African ancestry affects gene expression
The percentage of African ancestry in a person's genome determines the level that certain genes are expressed, called mRNA, according to a new Northwestern Medicine study. The discovery could offer insight into the different risk of diseases as well as a different response to medications in African Americans. This is the first study to compare gene production between African Americans. Previous...
Pharmacy service will save NHS £651 million
A research team from the Universities of Manchester, Nottingham, and UCL evaluating a service delivered by pharmacists since 2011 have calculated it will save the English NHS around £651 million.
Pot while pregnant: UNLV medicine doctors urge caution
Daily marijuana use during pregnancy may lead to an increased risk of low birth weight, low resistance to infection, decreased oxygen levels and other negative fetal health outcomes, according to a new study from a team of UNLV Medicine doctors.
Protein defect leaves sperm chasing their tails
A team led by researchers from Osaka University 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...
Reflecting on photos helps young cancer survivors regain confidence
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...
Researchers at IRB Barcelona study how altered protein degradation contributes to the development of tumors
Published in the journal Nature Cancer, the study analyses how genetic alterations in tumour cells prevent the correct degradation of the proteins involved in tumour development and growth, thereby leading to abnormal cell behaviour.A machine-learning model has allowed the scientists to obtain the most extensive annotation of the ubiquitin-mediated protein degradation system.The analysis proposes...
Researchers compare nutritional value of infant and toddler foods
Infant and toddler foods sold in pouches have lower nutritional value than foods sold in jars and other packaging, according to a new study led by researchers from the University of Colorado Anschutz Medical Campus. The findings of the study are published in the current issue of the journal Nutrition Today.
Researchers find clue to preventing addiction relapse
A study published in Neuropsychopharmacology reported that relapse can be prevented by controlling cells in a brain region called the nucleus accumbens. The study was conducted among 90 Sprague Dawley rats with genetic diversity.
Researchers find protein promotes cancer, suppresses anti-tumor immunity
Researchers at The University of Texas MD Anderson Cancer Center have found that a protein involved in immune response to microbes, TBK1, also can fuel cancer development and suppress immune response to the disease.
Researchers identify a process responsible for therapeutic resistance in breast cancer
Researchers at the Lady Davis Institute have identified a key protein that is required for resistance to chemotherapy in the most aggressive form of breast cancer. This holds the promise of opening the door to new therapies for overcoming drug resistance.
Researchers investigate the effects of eye movements when reading texts in different languages
The existence of language universality has been a key issue in psychology and linguistics, since the understanding of universals is crucial for the development of information perception models. In the course of their in-depth study of linguistic universality, Lobachevsky University researchers studied readers' eye movements when reading texts in different languages. The research was aimed at...
Researchers may have discovered where HIV takes refuge during antiretroviral treatment
An international team led by Professor Jerome Estaquier from Universite Laval's Faculty of Medicine may have discovered where in the body HIV takes refuge during antiretroviral treatment. Research conducted using an animal model indicates that the virus may hide in lymph nodes in the spleen and gut. The researchers believe those lymph nodes are the staging ground from which the virus prepares to...
Revealed: The deadly superbugs lurking in more than 9 in 10 make-up bags
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 from Aston University published in the Journal of Applied Microbiology has revealed.
Satellite imagery shows Typhoon Kammuri's center obscured
NASA-NOAA's Suomi NPP or S-NPP satellite passed over the Philippine Sea in the Northwestern Pacific Ocean and found Typhoon Kammuri's eye obscured.
Scientist leads international team to crack 60-year-old mystery of Sun's magnetic waves
A Queen's University Belfast scientist has led an international team to the ground-breaking discovery of 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.
Scientists reveal the structure of viral rhodopsins
The structure of an Organic Lake Phycodnavirus rhodopsin II (OLPVRII), which is a unique protein found in the genome of giant viruses, has been determined thanks to the work of MIPT graduates and PhD students.
Significant developments in gamut mapping for the film industry
Presented in an article published on Nov. 14 in the journal IEEE Transactions on Pattern Analysis and Machine Intelligence by Syed Waqas Zamir, a researcher at the Inception Institute of Artificial Intelligence, Abu Dhabi (UAE); along with Javier Vázquez-Corral and Marcelo-BertalmÃo, researchers at the Department of Information and Communication Technologies.
Smarter strategies
Though small and somewhat nondescript, quagga and zebra mussels pose a huge threat to local rivers, lakes and estuaries. Thanks to aggressive measures to prevent contamination, Santa Barbara County's waters have so far been clear of the invasive mollusks, but stewards of local waterways, reservoirs and water recreation areas remain vigilant to the possibility of infestation by these and other...
