Researchers discover safe and efficient way to get large molecules through the cell membrane

Living cells are surrounded by a membrane that tightly regulates what gets in and out of the cell. This barrier is necessary for cells to control their internal environment, but it makes it more difficult for scientists to deliver large molecules such as nanoparticles for imaging, or proteins that can reprogram them into pluripotent stem cells.

Social isolation increases risk of addiction to amphetamine and alcohol

Rats that are socially isolated during a critical period of adolescence are more vulnerable to addiction to amphetamine and alcohol, found researchers at The University of Texas at Austin. Amphetamine addiction is also harder to extinguish in the socially isolated rats.

Research team describes how the brain controls whisker movements in mice

All parents know the infant milestones: turning over, learning to crawl, standing, and taking that first unassisted step. Achieving each accomplishment presumably requires the formation of new connections among subsets of the billions of nerve cells in the infant's brain. But how, when and where those connections form has been a mystery.

Researchers discover unique hairpin-like structure that facilitates Abeta clumping

Alzheimer's disease is the most common cause of late-life dementia. The disorder is thought to be caused by a protein known as the amyloid-beta protein, or Abeta, which clumps together in the brain, forming plaques that are thought to destroy neurons. This destruction starts early, too, and can presage clinical signs of the disease by up to 20 years.

Biomedical engineers identify natural switch that controls breast cancer metastasis

With a desire to inhibit metastasis, Cornell biomedical engineers have found the natural switch between the body's inflammatory response and how malignant breast cancer cells use the bloodstream to spread.

Boosting estrogen levels may help reduce urinary infections in menopausal women

Estrogen levels drop dramatically in menopause, a time when the risk of urinary tract infections increases significantly.

Study examines associations between blood calcium and ovarian cancer

A new study from Wake Forest Baptist Medical Center is the first to report that high blood calcium levels might predict ovarian cancer, the most fatal of the gynecologic cancers.

Normalizing p62 protein levels in immune system cells could reduce infection in CF patients

New research suggests that lowering excessive levels of a protein in immune system cells could be a strategy to clear an infection that is deadly to patients with cystic fibrosis (CF).

Mice with reduced caloric intake accumulate longer telomeres

One of the indicators of a cell's health is the state of its DNA and containers-the chromosomes-so when these fuse together or suffer anomalies, they can become the source of illnesses like cancer and/or ageing processes.

Hyperbaric treatment restores neurological function in damaged brains

Stroke, traumatic injury, and metabolic disorder are major causes of brain damage and permanent disabilities, including motor dysfunction, psychological disorders, memory loss, and more. Current therapy and rehab programs aim to help patients heal, but they often have limited success.

Catenin required in odontoblasts for tooth root formation

Today, the International and American Associations for Dental Research (IADR/AADR) published a paper titled "--catenin is Required in Odontoblasts for Tooth Root Formation." The paper, written by lead authors Tak-Heun Kim and Cheol-Hyeon Bae, Chonbuk National University Korea School of Dentistry, Laboratory for Craniofacial Biology, is published in the IADR/AADR Journal of Dental Research.

KLF6-SV1 gene variant drives the spread of breast cancer

A team of researchers led by Goutham Narla, MD, PhD, at Case Western Reserve University School of Medicine and University Hospitals Case Medical Center, and collaborators at the Mount Sinai School of Medicine and Erasmus Medical Center, have discovered a gene variant that drives the spread of breast cancer.

Study identifies how astrocytes regulate a neurotransmitter involved in sleep

Neuroscience researchers from Tufts University have found that our star-shaped brain cells, called astrocytes, may be responsible for the rapid improvement in mood in depressed patients after acute sleep deprivation. This in vivo study, published in the current issue of Translational Psychiatry, identified how astrocytes regulate a neurotransmitter involved in sleep.

Scientists identify consistent epigenetic signatures in men with metastatic prostate cancer

In a genome-wide analysis of 13 metastatic prostate cancers, scientists at the Johns Hopkins Kimmel Cancer Center found consistent epigenetic "signatures" across all metastatic tumors in each patient.

New apatamer can boost therapeutic effect of cell-based vaccines

A small compound called an aptamer that specifically targets and stimulates a human immune cell can greatly increase the effectiveness of an immunotherapeutic drug designed to destroy malignant or virus-infected cells. The development of a novel apatamer that recognizes activated T-lymphocytes and can boost the therapeutic effect of cell-based vaccines is described in an article in Nucleic Acid Therapeutics, a peer-reviewed journal from Mary Ann Liebert, Inc. publishers.

Journal of Unsolved Questions presents 5th issue on 'scientific labor'

In its recently published 5th issue, the Journal of Unsolved Questions (JUnQ) invites readers to take a look behind the doors of researchers' offices and laboratories, presenting "reports from the academic workforce". Researchers from archeology to neurology were invited to reflect upon "Scientific Labor". With this cover topic, JUnQ continues its endeavor to promote a realistic view of academic work.

BH3-mimetics might be new option for treatment of autoimmune conditions

Melbourne researchers have discovered that the death of immune system cells is an important safeguard against the development of diseases such as type 1 diabetes, rheumatoid arthritis and lupus, which occur when the immune system attacks the body's own tissues.
