After 15 years in a vegetative state, nerve stimulation restores consciousness

Mon, 25 Sep 17 00:06:40 -0700

A 35-year-old man who had been in a vegetative state for 15 years after a car accident has shown signs of consciousness after neurosurgeons implanted a vagus nerve stimulator into his chest. The findings reported in Current Biology on Sept. 25 show that vagus nerve stimulation (VNS) -- a treatment already in use for epilepsy and depression--can help to restore consciousness even after many years in a vegetative state.

Rainbow colors reveal cell history

Fri, 22 Sep 17 00:02:20 -0700

Dr. Nikolay Ninov, group leader at the DFG research center for Regenerative Therapies Dresden, Cluster of Excellence at the TU Dresden, and Paul Langerhans Institute Dresden, and his group developed a system called 'Beta-bow,' which allows the history of β-cells to be traced by genetic bar-coding and multicolor imaging. The results of this study are now published in the scientific journal Nature Communications.

Russian scientists have studied the genes that allow cancer cells to resist drugs

Fri, 22 Sep 17 00:02:30 -0700

Researchers from the People's Friendship University of Russia (RUDN University) have studied the mechanism of drug resistance for ovarian and breast cancer cells. They discovered that these cancer cells have redox-dependent mechanism which is tasked with sustaining their drug resistance. The results have been published in two articles in the journal of Free Radical Biology and Medicine.

Production of key diabetes cells can be improved

Thu, 21 Sep 17 00:02:20 -0700

In the future diabetics might benefit from getting insulin-regulating beta cells transplanted into their body because their own beta cells are destroyed or less functional. However, according to new stem cell research at the University of Copenhagen, the current way of producing beta cells from stem cells has significant shortfalls. The beta cells produced have some features resembling alpha cells.

Changing of the guard -- research sheds light on how plants breathe

Thu, 21 Sep 17 00:02:10 -0700

New research is set to change the textbook understanding of how plants breathe.

Mitochondria drive cell survival in times of need

Thu, 21 Sep 17 00:05:20 -0700

McGill University researchers have discovered a mechanism through which mitochondria, the energy factory of our body's cells, play a role in preventing cells from dying when the cells are deprived of nutrients - a finding that points to a potential target for next-generation cancer drugs.

DNA discovery could help shed light on rare childhood disorder

Thu, 21 Sep 17 00:07:10 -0700

Fresh analysis of how our cells store and manage DNA when they undergo cell division could give valuable insights into a rare developmental condition known as Cornelia de Lange syndrome.

Neuron types in brain are defined by gene activity shaping their communication patterns

Thu, 21 Sep 17 00:07:20 -0700

In a major step forward, scientists at CSHLtoday publish a discovery about the molecular-genetic basis of neuronal cell types. Neurons are the basic building blocks that wire up brain circuits supporting mental activities and behavior. The study, which involves sophisticated computational analysis of the messages transcribed from genes that are active in a neuron, points to patterns of cell-to-cell communication as the core feature that makes possible rigorous distinctions among neuron types across the mouse brain.

Ancient DNA data fills in thousands of years of human prehistory in Africa

Thu, 21 Sep 17 00:09:00 -0700

By sequencing the ancient genomes of 15 individuals from different parts of Africa, researchers reporting in the journal Cell on Sept. 21 have reconstructed the prehistory of humans on the continent, going back thousands of years. The findings shed light on which human populations lived in eastern and southern Africa between 8,000 and 1,000 years ago, the researchers say.

Your neurons register familiar faces, whether you notice them or not

Thu, 21 Sep 17 00:09:10 -0700

When people see an image of a person they recognize particular cells light up in the brain. Now, researchers reporting in Current Biology have found that those cells light up even when a person sees a familiar face or object but fails to notice it. The only difference is that the neural activity is weaker and delayed in comparison to what happens when an observer consciously registers and can recall having seen a particular image.

Alternative splicing, an important mechanism for cancer

Thu, 21 Sep 17 00:15:10 -0700

Scientists discover several alterations in this cellular process with implications in cancer by analyzing samples from more than 4,000 patients.

Rolling dice for cell size specification in plant leaf epidermis

Wed, 20 Sep 17 00:14:30 -0700

Associate Professor Kensuke Kawade at Okazaki Institute for Integrative Bioscience and National Institute for Basic Biology, in collaboration with Professor Hirokazu Tsukaya at the Graduate School of Science, the University of Tokyo, discovered that endoreduplication, which promotes cellular enlargement in the epidermal tissue of Arabidopsis thaliana, occurs randomly as a Poisson process throughout cellular maturation.
