Faulty ‘eat-me’ signal may trigger neurodegeneration

The nervous system is a complex network of neurons that coordinates the body by transmission of electrical signals. And just like the power lines that deliver electricity to homes and businesses, the nervous system sometimes needs maintenance. During early development, animals are constantly eliminating unnecessary neuronal material; the nervous systems […]

Protein Modifications that Point to Cancer

Researchers from the University of Zurich can, for the first time, precisely characterize the protein modification ADP-ribosylation for all proteins in a tissue sample. The changes, which are a typical reaction to stress, provide information about the condition of a cell. Together with the University Hospital Zurich, they are now […]

Maple leaf extract could nip skin wrinkles in the bud

Maple trees are best known for their maple syrup and lovely fall foliage. But it turns out that the beauty of those leaves could be skin-deep — and that’s a good thing. Today, scientists report that an extract from the leaves may prevent wrinkles. The scientists had previously studied the […]

New drug could prevent debilitating side effect of cancer treatment

About 50,000 people in the U.S. are diagnosed annually with head, neck, nasal and oral cancers. Most are treated with radiation, and of those, 70-80 percent develop a painful and debilitating side effect called severe oral mucositis (SOM). While some drugs are available to treat SOM once it develops, none […]

Beluga whales and narwhals go through menopause

Scientists have discovered that beluga whales and narwhals go through the menopause – taking the total number of species known to experience this to five. Aside from humans, the species now known to experience menopause are all toothed whales – belugas, narwhals, killer whales and short-finned pilot whales. Almost all […]

One night of sleep loss negatively impacts fat, muscle tissue

Losing just one night of sleep can have a negative impact on human metabolism at the tissue level, according to a study published last week. The findings may explain how long-term shift work and chronic sleep loss can impair metabolism and adversely affect human body composition. Previous studies have shown that the risk […]

New Understanding of Glaucoma

Immune cells in the eye that developed in response to early exposure to bacteria are a key contributor to progressive vision loss from glaucoma, the second leading cause of irreversible blindness in the world, according to new research from Harvard Medical School, Massachusetts Eye and Ear and MIT. The findings, published […]

NIH-funded researchers reverse congenital blindness in mice

Researchers funded by the National Eye Institute (NEI) have reversed congenital blindness in mice by changing supportive cells in the retina called Müller glia into rod photoreceptors. The findings advance efforts toward regenerative therapies for blinding diseases such as age-related macular degeneration and retinitis pigmentosa. A report of the findings […]

NIH-led research team develops predictor for immunotherapy response in melanoma

In a new study, researchers developed a gene expression predictor that can indicate whether melanoma in a specific patient is likely to respond to treatment with immune checkpoint inhibitors, a novel type of immunotherapy. The predictor was developed by Noam Auslander, Ph.D., with other researchers in the Center for Cancer […]

High-speed atomic force microscopy reveals clock protein interactions

For the first time, researchers have seen how proteins involved in the daily biological clock interact with each other, helping them to further understand a process tied to numerous metabolic and eating disorders, problems with shift work, jet lag and mental health issues. Working with the clock proteins KaiA, KaiB […]

New technology can detect hundreds of proteins in a single sample

New technology developed by a team of McGill University scientists shows potential to streamline the analysis of proteins, offering a quick, high volume and cost-effective tool to hospitals and research labs alike. Proteins found in blood provide scientists and clinicians with key information on our health. These biological markers can […]

Tissue architecture affects chromosome segregation

All growth and reproduction relies on a cell’s ability to replicate its chromosomes and produce accurate copies of itself. Every step of this process takes place within that cell. Based on this observation, scientists have studied the replication and segregation of chromosomes as a phenomenon exclusively internal to the cell. They […]

Scientists propose a new leader for Alzheimer's research

A University of Adelaide-led team of scientists has suggested a potential link between iron in our cells and the rare gene mutations that cause Alzheimer’s disease, which could provide new avenues for future research. In a paper published in the journal Frontiers in Neuroscience, the team proposes a new theory […]

Cellular Escape Artists

More than two-thirds of women with ovarian cancer have high-grade serous carcinoma (HGSC). Up to 90 percent of HGSCs are not detected until they are beyond the ovaries or fallopian tubes, at which point it may not be possible to fully remove the tumor. Many of these cancers are now […]

Epigenetic patterns determine if honeybee larvae become queens or workers

Queen and worker honeybees are almost genetically identical but are fed a different diet as larvae. The researchers have found that specific protein patterns on their genome play an important role in determining which one they develop into. These proteins, known as histones, act as switches that control how the […]
