Bats bolster brain hypothesis, maybe technology, too

Bats bolster brain hypothesis, maybe technology, too

Amid a neuroscience debate about how people and animals focus on distinct objects within cluttered scenes, some of the newest and best evidence comes from the way bats “see” with their ears, according to a new paper in the Journal of Experimental Biology . In fact, the perception process in question could improve sonar and radar technology. Continue reading

New ways to treat solid tumors using protein

New ways to treat solid tumors using protein

An international team of scientists has shown that an antibody against the protein EphA3, found in the micro-environment of solid cancers, has anti-tumor effects. As EphA3 is present in normal organs only during embryonic development but is expressed in blood cancers and in solid tumors, this antibody-based approach may be a suitable candidate treatment for solid tumors. The researchers from Monash University and Ludwig Cancer Research, in Australia, and KaloBios Pharmaceuticals, in the US, have had their findings published in the journal Cancer Research .

Personal, public costs of scientific misconduct calculated

Personal, public costs of scientific misconduct calculated

Much has been assumed about the private and public damage of scientific misconduct. Yet few have tried to measure the costs to perpetrators and to society. A recent study calculated some of the career impacts, as well as federal funding wasted, when biomedical research papers are retracted Continue reading

Novel treatment strengthens bones in genetic disease neurofibromatosis type-1

Novel treatment strengthens bones in genetic disease neurofibromatosis type-1

An enzyme therapy may prevent skeletal abnormalities associated with the genetic disorder neurofibromatosis type-1, Vanderbilt investigators have discovered. The researchers demonstrated in a mouse model of the disorder that the enzyme asfotase-alpha improves bone growth, mineralization and strength. Continue reading

New technology offers insight into cholesterol

New technology offers insight into cholesterol

With new advanced techniques developed by the Copenhagen Center for Glycomics at the University of Copenhagen it is possible to study cells in greater detail than ever before. The findings have just been published in the Journal of Biological Chemistry and may, in the long term, improve the treatment of high cholesterol Continue reading

With new advanced techniques developed by the Copenhagen Center for Glycomics at the University of Copenhagen it is possible to study cells in greater detail than ever before. The findings have just been published in the Journal of Biological Chemistry and may, in the long term, improve the treatment of high cholesterol. Researchers from the Copenhagen Center for Glycomics at the University of Copenhagen have studied an important receptor protein called LDLR using new, groundbreaking techniques Continue reading

Tissue development ‘roadmap’ created to guide stem cell medicine

Tissue development ‘roadmap’ created to guide stem cell medicine

In a boon to stem cell research and regenerative medicine, scientists at Boston Children’s Hospital, the Wyss Institute for Biologically Inspired Engineering at Harvard University and Boston University have created a computer algorithm called CellNet as a “roadmap” for cell and tissue engineering, to ensure that cells engineered in the lab have the same favorable properties as cells in our own bodies.

Cell discovery brings blood disorder cure closer

Cell discovery brings blood disorder cure closer

A cure for a range of blood disorders and immune diseases is in sight, according to scientists who have unravelled the mystery of stem cell generation. Continue reading

Mouth bacteria can change its diet, supercomputers reveal

Mouth bacteria can change its diet, supercomputers reveal

Bacteria inside your mouth drastically change how they act when you’re diseased, according to research using supercomputers at the Texas Advanced Computing Center (TACC). Scientists say these surprising findings might lead to better ways to prevent or even reverse the gum disease periodontitis, diabetes, and Crohn’s disease. Marvin Whiteley, professor of molecular biosciences and director of the Center for Infectious Disease at The University of Texas at Austin, led the study published in April 2014 in the journal mBio .

Our ancestor’s ‘leaky’ membrane answers big questions in biology

Our ancestor’s ‘leaky’ membrane answers big questions in biology

All life on Earth came from one common ancestor — a single-celled organism — but what it looked like, how it lived and how it evolved into today’s modern cells is a four billion year old mystery being solved by researchers at UCL using mathematical modelling. Findings published in PLOS Biology suggest for the first time that life’s Last Universal Common Ancestor (LUCA) had a ‘leaky’ membrane, which helps scientists answer two of biology’s biggest questions: 1.
