Researchers at the University of Dundee have developed an unrivalled, fully automated robotic screening system which allows them to rapidly test the effect of drugs and other chemicals on human sperm.
The research team at Dundee, led by Professor Chris Barratt and Dr Paul Andrews, are working towards finding a safe and effective male contraceptive.
Results of their latest study, funded by the Bill & Melinda Gates Foundation, are published in the journal eLife.
New insight on how information relating to sound and movement is processed in the brain has been published today in the open-access journal eLife.
The study in mice suggests that both sound and movement are processed simultaneously in part of the brain called the inferior colliculus (IC), a region that is best known for sound processing only. The findings also show how the brain may prevent movement-related sounds from interfering with the animals' hearing as they travel.
Experts in population mapping at the University of Southampton have identified cities and provinces within mainland China, and cities and countries worldwide, which are at high-risk from the spread of the 2019 Novel Coronavirus (2019-nCoV).
A group led by a researcher affiliated with the University of São Paulo's São Carlos Chemistry Institute (IQSC-USP) in Brazil has developed a novel palladium compound that acts against ovarian tumor cells without affecting healthy tissues. Palladium is a silvery white metal belonging to the same group as platinum.
Researchers from Aalto University, the University of São Paulo and the University of British Columbia have found a way to make a new kind of fibre from a combination of chitin nanoparticles, extracted from residual blue crab shells and alginate, a compound found in seaweed. This new bio-based material is sturdy and has antimicrobial properties.
Scientists from the Walter Reed Army Institute of Research have demonstrated that a novel, second-generation malaria vaccine candidate based on the tobacco mosaic virus may offer protection against Plasmodium falciparum malaria in the upcoming issue of the journal Proceedings of the National Academy of Sciences.
Beth MacKay knew at a young age that she saw the world differently than many of her friends and family. She thought her pessimism and cynicism were rooted in realism, a proud reminder of her Scottish roots, and not a sign of an underlying medical condition. But, that understanding of herself changed when at the age of 17, she attempted suicide.
NEW ORLEANS, Louisiana (January 27, 2020) -- A groundbreaking tumor-highlighting technology--OTL38--enhances the visualization of lung cancer tissue, providing surgeons with a significantly better chance of finding and removing more cancer than previously possible, according to a scientific presentation at the 56th Annual Meeting of The Society of Thoracic Surgeons.
Your bone marrow produces about 500 billion new blood cells every single day - roughly equivalent to the number of stars thought to be in the Milky Way. Being so prolific, however, comes with a price: medical interventions that aim to disrupt cell growth and differentiation, such as chemotherapies and radiation, can hit the bone marrow extremely hard, causing serious side effects like anemia, severe bleeding, and increased infections.
(BOSTON) -- Drug development is an extremely arduous and costly process, and failure rates in clinical trials that test new drugs for their safety and efficacy in humans remain very high. According to current estimates, only 13.8% of all tested drugs demonstrate ultimate clinical success and obtain approval by the Food and Drug Administration (FDA). There are also increasing ethical concerns relating to the use of animal studies. As a result, there has been a world-wide search to find replacements for animal models.
Using the latest satellite technology from the European Space Agency (ESA), scientists from the University of Bristol have been tracking patterns of mass loss from Pine Island - Antarctica's largest glacier.
They found that the pattern of thinning is evolving in complex ways both in space and time with thinning rates now highest along the slow-flow margins of the glacier, while rates in the fast-flowing central trunk have decreased by about a factor of five since 2007. This is the opposite of what was observed prior to 2010.
Irvine, Calif. - A neural network-driven Earth system model has led University of California, Irvine oceanographers to a surprising conclusion: phytoplankton populations will grow in low-latitude waters by the end of the 21st century.
COLUMBUS, Ohio - The materials the United States and other countries plan to use to store high-level nuclear waste will likely degrade faster than anyone previously knew because of the way those materials interact, new research shows.
The findings, published today in the journal Nature Materials, show that corrosion of nuclear waste storage materials accelerates because of changes in the chemistry of the nuclear waste solution, and because of the way the materials interact with one another.
Despite being "neotropical-forest-loving creatures," some orchid bees are known to tolerate habitats disturbed by human activity. However, little did the research team of Paola Galgani-Barraza (Smithsonian Tropical Research Institute) expect to find as many as 120 clusters of nearly two-centuries-old orchid bee nests built on the altarpiece of the Basilica Cathedral in Casco Viejo (Panamá).
The sentencing of Reynhard Sinaga, the most prolific convicted rapist in British history, who preyed on men in Manchester, was shocking and destroyed the myth that only women are raped and sexually abused.
Now, a call for a complete review of national support services for male survivors of sexual violence and abuse has been made following a study by Lancaster University, launched today.
