Lack of thyroid hormone blocks hearing development

Lack of thyroid hormone blocks hearing development

Fatigue, weight gain, chills, hair loss, anxiety, excessive perspiration — these symptoms are a few of the signs that the thyroid gland, which regulates the body’s heart rate and plays a crucial role in its metabolism, has gone haywire. Now, new research from Tel Aviv University points to an additional complication caused by thyroid imbalance: congenital deafness. Continue reading

Food Memory: New discovery outlines how we remember taste experiences

Food Memory: New discovery outlines how we remember taste experiences

Have you ever eaten something totally new and it made you sick? Don’t give up; if you try the same food in a different place, your brain will be more “forgiving” of the new attempt Continue reading

New cancer drug target involving lipid chemical messengers

New cancer drug target involving lipid chemical messengers

More than half of human cancers have abnormally upregulated chemical signals related to lipid metabolism, yet how these signals are controlled during tumor formation is not fully understood. Youhai Chen, PhD, MD, and Svetlana Fayngerts, PhD, both researchers in the department of Pathology and Laboratory Medicine at the Perelman School of Medicine, University of Pennsylvania, and colleagues report that TIPE3, a newly described oncogenic protein, promotes cancer by targeting these pathways. Lipid second messengers play cardinal roles in relaying and amplifying signals from outside the cell to its interior and outer membrane Continue reading

Genetically driven gut feelings help female flies choose a mate

Genetically driven gut feelings help female flies choose a mate

Even among flies, mating is a complicated ritual. Their elaborate, and entirely innate, courtship dance combines multiple motor skills with advanced sensory cues. Now, researchers at Rockefeller University have determined that the Abdominal-B ( Abd-B ) gene, previously known as the gene that sculpts the posterior parts of the developing fly, is also important for this complex behavior, at least in the case of female flies ( Drosophila melanogaster) Continue reading

Wireless sensor transmits tumor pressure

Wireless sensor transmits tumor pressure

The interstitial pressure inside a tumor is often remarkably high compared to normal tissues and is thought to impede the delivery of chemotherapeutic agents as well as decrease the effectiveness of radiation therapy. While medications exist that temporarily decrease tumor pressure, identifying the optimal window to initiate treatment — when tumor pressure is lowest — remains a challenge Continue reading

New biomedical implants heal bones faster, focus on personalized medicine

New biomedical implants heal bones faster, focus on personalized medicine

A major success in developing new biomedical implants with the ability to accelerate bone healing has been reported by a group of scientists from the Department of Restorative Dentistry, University of Malaya. This stems from a project partly funded by HIR and also involves Mr. Continue reading

Exercise boosts tumor-fighting ability of chemotherapy, team finds

Exercise boosts tumor-fighting ability of chemotherapy, team finds

Study after study has proven it true: exercise is good for you. But new research from University of Pennsylvania scientists suggests that exercise may have an added benefit for cancer patients undergoing chemotherapy. Their work, performed in a mouse model of melanoma, found that combining exercise with chemotherapy shrunk tumors more than chemotherapy alone. Continue reading

VIP: New way to prevent spread of devastating diseases

VIP: New way to prevent spread of devastating diseases

For decades, researchers have tried to develop broadly effective vaccines to prevent the spread of illnesses such as HIV, malaria, and tuberculosis. While limited progress has been made along these lines, there are still no licensed vaccinations available that can protect most people from these devastating diseases. So what are immunologists to do when vaccines just aren’t working Continue reading

A new quality control pathway in the cell

A new quality control pathway in the cell

Proteins are important building blocks in our cells and each cell contains millions of different protein molecules. They are involved in everything from structural to regulatory aspects in the cell Continue reading

First blood test to diagnose depression in adults

First blood test to diagnose depression in adults

The first blood test to diagnose major depression in adults has been developed by Northwestern Medicine® scientists, a breakthrough approach that provides the first objective, scientific diagnosis for depression. The test identifies depression by measuring the levels of nine RNA blood markers. RNA molecules are the messengers that interpret the DNA genetic code and carry out its instructions. Continue reading
