Novel tactile conditioning experiment using honey bees

Honey bees are a highly organized, social species, as demonstrated by their complex colonies and the geometric structure of their hives. For hive building, the honey bee strongly relies on its tactile sense, and a new video-article in JoVE (Journal of Visualized Experiments) illustrates a novel tactile conditioning experiment using honey bees.

TSEC strategy can benefit postmenopausal women

Investigators at Wake Forest Baptist Medical Center have concluded research on a new postmenopausal hormone therapy that shows promise as an effective treatment for menopausal symptoms and the prevention of osteoporosis without increasing the risk for heart disease or breast cancer.

Patients with multiple sclerosis have low levels of Egr2/3 protein in T lymphocytes

Researchers from Queen Mary, University of London have discovered that two proteins which are believed to play a key role in controlling the body's immune response are found in lower levels in T lymphocytes from patients with multiple sclerosis (MS).

AZD6765 briefly improves treatment-resistant patients' depression symptoms in minutes

A drug that works through the same brain mechanism as the fast-acting antidepressant ketamine briefly improved treatment-resistant patients' depression symptoms in minutes, with minimal untoward side effects, in a clinical trial conducted by the National Institutes of Health. The experimental agent, called AZD6765, acts through the brain's glutamate chemical messenger system.

Study investigates different approaches to eradicate mosquito-borne diseases

A special issue of Pathogens and Global Health, published by Maney Publishing, investigates different approaches to eradicate mosquito-borne diseases. Mosquitoes can transmit a number of pathogenic diseases including dengue fever, yellow fever, and malaria.

Study finds many patients with family history of LINE-1 hypomethylated colorectal cancer

When people with a family history of colorectal cancer develop the disease, their tumors often carry a molecular sign that the cancer could be life-threatening and may require aggressive treatment, Dana-Farber Cancer Institute scientists report in a new study.

Researchers discover a trigger by which the HCV enters liver cells

Researchers at the University of Southern California (USC) have discovered a trigger by which the Hepatitis C virus enters liver cells ─ shedding light on how this serious and potentially deadly virus can begin to damage the liver.

Skin vibrations convey information to the brain much the same way as auditory system

When you walk into a darkened room, your first instinct is to feel around for a light switch. You slide your hand along the wall, feeling the transition from the doorframe to the painted drywall, and then up and down until you find the metal or plastic plate of the switch. During the process you use your sense of touch to develop an image in your mind of the wall's surface and make a better guess for where the switch is.

American Association of Anatomist announces winners of Young Investigator Awards

The American Association of Anatomist's (AAA) Young Investigator Awards combine three long-standing AAA awards-Bensley, Herrick, and Mossman-with the Morphological Sciences Award, all recognizing investigators in the early stages of their careers who have made important contributions to biomedical science through their research in cell/molecular biology, developmental biology, comparative neuroanatomy, or the morphological sciences.

UBC researcher helps create new gel that could glue blood vessels back together

A University of British Columbia researcher has helped create a gel - based on the mussel's knack for clinging to rocks, piers and boat hulls - that can be painted onto the walls of blood vessels and stay put, forming a protective barrier with potentially life-saving implications.

TKI-resistant human leukemia stem cells are the source of genomic instability

An international team of scientists, led by researchers from Temple University School of Medicine, has found that a source of mounting genomic chaos, or instability, common to chronic myeloid leukemia (CML) may lie in a pool of leukemia stem cells that are immune to treatment with potent targeted anticancer drugs.

Drugs that bind to specific serotonin receptors can improve and impair female sexual function

Drugs that bind to specific serotonin receptors in the brain can both improve and impair female sexual function in non-human primates.

Scientists determine specific genetic switches that sync liver activity to the circadian cycle

When it's dark, and we start to fall asleep, most of us think we're tired because our bodies need rest. Yet circadian rhythms affect our bodies not just on a global scale, but at the level of individual organs, and even genes.

Link between CTNNA3 gene mutations and arrhythmogenic right ventricular cardiomyopathy

Unfortunately, newspaper articles about young athletes dying suddenly on the field are not unheard of. Such reports fuel discussions about compulsory screening, for example of young footballers, for heart failure. Research by scientists from Ghent (VIB/UGent) and Italy will benefit these screening methods.

Epi-marks can lead to homosexuality

Epigenetics - how gene expression is regulated by temporary switches, called epi-marks - appears to be a critical and overlooked factor contributing to the long-standing puzzle of why homosexuality occurs.

U-M devises new system to capture and study circulating tumor cells

A glass plate with a nanoscale roughness could be a simple way for scientists to capture and study the circulating tumor cells that carry cancer around the body through the bloodstream.

Oncogene-induced senescence could play a key role in future cancer therapy

Cell aging, or cellular senescence, has an important role in the natural physiological response to tumor development. Activated oncogenes are able to induce senescence, and recent findings have suggested that oncogene-induced senescence (OIS) could play a key role in future cancer therapy.
