Brookhaven scientists receive patent for improved cancer therapy device

Four physicists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have been awarded U.S. Patent No. 7,432,516 B2 for the design of a "medical synchrotron" capable of delivering precision doses of proton radiation to cancerous tumors with minimal damage to surrounding healthy tissue.

Scientists find cells reorganize shape to fit situation

Flip open any biology textbook and you're bound to see a complicated diagram of the inner workings of a cell, with its internal scaffolding, the cytoskeleton, and how it maintains a cell's shape.

Researchers shed new light on genetics of Parkinson's

A new study by Narendra et al. suggests that Parkin, the product of the Parkinson's disease-related gene Park2, prompts neuronal survival by clearing the cell of its damaged mitochondria.

Researchers show how a cell motor protein exerts the force to move

Kinesin, a motor protein that also carries neurotransmitters, "walks" along cellular beams known as microtubules. For the first time, the MIT team has shown at a molecular level how kinesin generates the force needed to step along the microtubules.

Medarex starts phase 1b clinical trial with MDX-1106 for the treatment of cancer

Medarex, Inc. has announced it has initiated a Phase 1b clinical trial for MDX-1106 (ONO-4538: development code of Ono Pharmaceutical Co., Ltd.), a fully human anti-PD-1 antibody for the treatment of cancer.

Evidence of retina self-repair in mammals

Researchers at the University of Washington (UW) have reported for the first time that mammals can be stimulated to regrow inner nerve cells in their damaged retinas.

Humoral immunity in kidney transplantation

There are more than 76,000 end-stage renal disease patients waiting for one of the 17,000 kidneys transplanted each year, making a host rejection an unacceptable waste.

New model predicts risk of recurrence in early stage colon cancer patients

Researchers in the Duke Institute for Genome Sciences & Policy have developed a model for predicting risk of recurrence in early stage colon cancer patients, and have used the model to also predict sensitivity to chemotherapy and targeted therapy regimens.

Understanding lipid storage

Magazine articles describing ways to burn fat, lose weight, etc. are omnipresent in Western culture, but science's understanding of the way fat is stored in the cells of the human body is rather slimmer.

Children with sickle cell disease have inadequate healthcare

A new study finds that youth populations with sickle cell disease (SCD) are receiving inadequate healthcare, and thus may fail to benefit from scientific advances.

Neurons in adult brain can remodel their connections

In work reported in the Nov. 24 online edition of the Proceedings of the National Academy of Sciences (PNAS) , Elly Nedivi, associate professor of neurobiology at the Picower Institute for Learning and Memory, and colleagues found that a type of neuron implicated in autism spectrum disorders remodels itself in a strip of brain tissue only as thick as four sheets of tissue paper at the upper border of cortical layer 2.

Scientists identify blood component that turns anthrax bacteria virulent

Scientists from the Scripps Research Institute have discovered the key chemical that signals Bacillus anthracis , the bacterium that causes anthrax, to become lethal.

Researchers discover mechanism vital to the development of the hippocampus

Astrophysicists peer into the far corners of deep space for dark matter, but for neuroscientists at the Queensland Brain Institute (QBI) exploring the unknown is much closer to home.

Mechanisms of cardiovascular disease and cancer give clues to new therapies

Cardiovascular conditions leading to heart attacks and strokes are treated quite separately from common cancers of the prostate, breast or lung, but now turn out to involve some of the same critical mechanisms at the molecular level.

NJISA experts available for interviews on Alzheimer's disease

An estimated five million Americans suffer from Alzheimer's, a disease that affects parts of the brain that control thought, memory, and language and is the most common form of dementia among older people.

Scientists discover an important new layer of regulation in the cell division cycle

A Florida State University College of Medicine research team led by Yanchang Wang has discovered an important new layer of regulation in the cell division cycle, which could lead to a greater understanding of the way cancer begins.

Non-pharmacologic interventions for the control of osteoporosis and obesity

The Department of Biomedical Engineering at Stony Brook University received a $1.8 million grant from the National Institutes of Health (NIH) to investigate the biologic and physical mechanisms of very low-magnitude mechanical signals and how they strengthen bone and muscle.

Scientists develop unlimited pure insulin-producing cells from mouse embryonic stem cells

These pure insulin-producing cells, which according to electron microscopy studies, have the same sub-cellular structures as the insulin-producing cells naturally found in the pancreas, were highly effective in treating diabetes in the mouse model.
