A team of researchers with the Mayo Clinic has learned more about how a transcription factor known as FOXA1 forms cancer-specific genomic identifiers and how it regulates gene expression differently among four very different types of human cancer cell lines. In their paper published in the journal Science Advances, the team describes how they used gene editing techniques and other tools to learn more about the unique binding process that allows t...

Sperm cells, as it turns out, can become 'hyperactive'. A new study published in the journal Science has revealed that a particular enzyme on their tails responds to the female sex hormone progesterone, activating a 'power kick' that boosts their swimming speed. The body produces various hormones all the time for different purposes. Progesterone is released, for example, just prior to and at the onset of pregnancy, particularly to prepare the ute...

Scientists have many tools at their disposal for looking at preserved tissue under a microscope in incredible detail, or peering into the living body at lower resolution. What they haven't had is a way to do both: create a three-dimensional real-time image of individual cells or even molecules in a living animal. Now, Stanford scientists have provided the first glimpse under the skin of a living animal, showing intricate real-time details in thre...

Designed and certified for medical applications, XP Power has announced the JHL and JHM series of encapsulated, isolated and regulated DC/DC converters. The 3W JHL03, 6W JHL06 and 15W JHM15 are approved to the 3rd edition international medical safety standards EN60601-1:2006 and ANSI/AAMI ES60601-1:2005, feature a low 2uA maximum patient leakage current and offer 2 x MOPP.

Carrots and apples not only taste different. They make distinct sounds when chewed. This may seem like trivial knowledge, but it's not in the laboratory of University at Buffalo computer scientist Wenyao Xu, who is creating a library that catalogues the unique sounds that foods make as we bite, grind and swallow them. The library is part of a software package that supports AutoDietary, a high-tech, food-tracking necklace being developed by Xu and...

Athletes, the elderly and others who suffer from injuries and arthritis can lose cartilage and experience a lot of pain. Researchers are now reporting, however, that they have found a way to produce cartilage tissue by 3D bioprinting an ink containing human cells, and they have successfully tested it in an in vivo mouse model. The development could one day lead to precisely printed implants to heal damaged noses, ears and knees.

  Using virtual reality technology, Vertual (a University of Hull-based company) is helping to transform the quality of cancer education in Africa.

The EU-funded COLUMNARCODECRACKING project has successfully used ultra-high fMRI scanners to map cortical columns, a process that opens the door to exciting new applications, such as brain-computer interfaces. Cortical columnar-level fMRI has already contributed and will further contribute to a deeper understanding of how the brain and mind work by zooming into the fine-grained functional organisation within specialised brain areas.

What if we could program living cells to do what we would like them to do in the body? Having such control could allow for the development of cell-based therapies that might one day replace traditional drugs for diseases such as cancer. In order to reach this long-term goal, however, scientists must first learn to program many of the key things that cells do, such as communicate with one another, change their fate to become a particular cell type...
