For cancer to spread, it needs a hospitable environment in distant organs. This fertile “soil” can provide a home to circulating malignant cells. Recent research has shown that cancer cells from the primary tumor can help ready this soil by sending out small vesicles. These vesicles contain a cocktail of […]

Gene defect in hereditary forms of the neurological disorder results in manganese poisoning inside cells. A new X-ray study has revealed one of the key mechanisms behind certain familial-parkinsonian disorders. The study demonstrates in detail how poisoning with the metal manganese occurs inside a cell, leading to parkinsonian symptoms. It […]

Everyone wants to live a long and healthy life. It is a bit of a goal that everyone has or should have. And we do our best – we work out, we get frequent check-ups, we eat healthy, but still, a big secret to longevity is our genes. Now scientists […]

Leaky capillaries in the brain portend early onset of Alzheimer’s disease as they signal cognitive impairment before hallmark toxic proteins appear, new USC research shows. The findings, which appeared in the journal Nature Medicine, could help with earlier diagnosis and suggest new targets for drugs that could slow or prevent the […]

Short-lived wild insects “get old” – losing some of their physical abilities – before they die, new research shows. Few studies have examined whether insects such as field crickets – whose adult life lasts a few weeks – experience “ageing” in the sense of physical decline in nature. Insects are used […]

Scientists have created the most comprehensive method yet to predict a woman’s risk of breast cancer, according to a study led by researchers at the University of Cambridge. The study, funded by Cancer Research, is published today in Genetics in Medicine. They have a developed a way of calculating the […]

Couples considering medically assisted reproduction (MAR) because they have difficulties conceiving naturally, have feared that they could do harm to their baby by opting for medical intervention. Doctors may warn that MAR raises the risk of preterm birth (less than 37 weeks of pregnancy) and low birth weight (less than […]

Differences in the geographic origin of genes may affect the function of human mitochondria — energy-generating organelles inside of cells — according to a new study. Mitochondria have their own genome, separate from the nuclear genome contained in the nucleus of the cell, and both genomes harbor genes integral to […]

For the first time, researchers at University of California San Diego School of Medicine and Institute of Engineering in Medicine have used rapid 3D printing technologies to create a spinal cord, then successfully implanted that scaffolding, loaded with neural stem cells, into sites of severe spinal cord injury in rats. […]

New research shows that healthy infants have intestinal bacteria that prevent the development of food allergies. Researchers from the University of Chicago, Argonne National Laboratory and the University of Naples Federico II in Italy found that when gut microbes from healthy human infants were transplanted into germ-free mice, the animals […]

A new investigation heading to the International Space Station will provide space-flown samples to scientists from academia, industry and government agencies, who have agreed to share their data and results in an online database that is open to the public. Rodent Research-8 (RR-8) examines the physiology of aging and the […]

Approach avoids potential toxicity Pacific Northwest National Laboratory and Washington State University researchers have developed a novel way to deliver drugs and therapies into cells at the nanoscale without causing toxic effects that have stymied other such efforts. The work could someday lead to more effective therapies and diagnostics for […]
