Cosmic rays threaten future deep-space astronaut missions

Cosmic rays threaten future deep-space astronaut missions

Crewed missions to Mars remain an essential goal for NASA, but scientists are only now beginning to understand and characterize the radiation hazards that could make such ventures risky, concludes a new paper by University of New Hampshire scientists. Continue reading

Treatment for osteoporosis, bone cancer, employed for the first time in dental filling procedures

Treatment for osteoporosis, bone cancer, employed for the first time in dental filling procedures

Journal of Dental Research publishes a paper directed by Salvatore Sauro, Professor at University CEU Cardenal Herrera in Spain, in collaboration with international researchers from Finland, Brazil, United States and United Kingdom. The research report has demonstrated how the use of zoledronic acid, in combination with bioactive ion-releasing resin-based restorative materials used as dental adhesive, reduces the degradation of dentin collagen and promotes remineralisation at the resin-dentine interface.

Positive subliminal messages on aging improve physical functioning in elderly

Positive subliminal messages on aging improve physical functioning in elderly

Older individuals who are subliminally exposed to positive stereotypes about aging showed improved physical functioning that can last for several weeks, a new study led by the Yale School of Public Health has found. Continue reading

‘Mega’ cells control growth of blood-producing cells

‘Mega’ cells control growth of blood-producing cells

While megakaryocytes are best known for producing platelets that heal wounds, these “mega” cells found in bone marrow also play a critical role in regulating stem cells according to new research from the Stowers Institute for Medical Research. In fact, hematopoietic stem cells differentiate to generate megakaryocytes in bone marrow. The Stowers study is the first to show that hematopoietic stem cells (the parent cells) can be directly controlled by their own progeny (megakaryocytes). Continue reading

Women driven by status, wealth rather than wanting babies, study suggests

Women driven by status, wealth rather than wanting babies, study suggests

A new study suggests that women are more driven to seek wealth and status than they are to reproduce. The research by Oxford University and Sheffield University says although low fertility may seem to go against traditional ideas about evolutionary success, a woman will delay and reduce her fertility if it brings her opportunities for higher status. The findings are based on interviews with 9,000 women in Mongolia, a country that underwent a sudden transition from a Soviet-style state to mass privatization Continue reading

Cystic Fibrosis lung infection: Scientists open black box on bacterial growth

Cystic Fibrosis lung infection: Scientists open black box on bacterial growth

Researchers from the University of Copenhagen have shown for the first time how bacteria can grow directly in the lungs of Cystic fibrosis patients, giving them the opportunity to get tremendous insights into bacteria behavior and growth in chronic infections. The study also discovered the bacterial growth in chronic lung infections among cystic fibrosis (CF) patients was halted or slowed down by the immune cells. The researchers discovered the immune cells consumed all the oxygen and helped “suffocate” the bacteria, forcing the bacteria to switch to a much slower growth. Continue reading

Scientists find ‘hidden brain signatures’ of consciousness in vegetative state patients

Scientists find ‘hidden brain signatures’ of consciousness in vegetative state patients

Scientists in Cambridge have found hidden signatures in the brains of people in a vegetative state, which point to networks that could support consciousness even when a patient appears to be unconscious and unresponsive. Continue reading

New mechanism that can lead to blindness discovered

New mechanism that can lead to blindness discovered

An important scientific breakthrough by a team of IRCM researchers led by Michel Cayouette, PhD, is being published by The Journal of Neuroscience . The Montréal scientists discovered that a protein found in the retina plays an essential role in the function and survival of light-sensing cells that are required for vision. These findings could have a significant impact on our understanding of retinal degenerative diseases that cause blindness Continue reading

Boosting heart’s natural ability to recover after heart attack

Boosting heart’s natural ability to recover after heart attack

Researchers from the UNC School of Medicine have discovered that cells called fibroblasts, which normally give rise to scar tissue after a heart attack, can be turned into endothelial cells, which generate blood vessels to supply oxygen and nutrients to the injured regions of the heart, thus greatly reducing the damage done following heart attack. This switch is driven by p53, the well-documented tumor-suppressing protein Continue reading
