Researchers develop hard X-ray laser to determine structure of biomolecules

Unraveling the molecular basis of life is an age-old quest of humanity. A breakthrough towards this goal was reported in a pair of studies published Feb. 3 in the scientific journal Nature, detailing a new method developed to determine structures of biomolecules based on diffraction from protein nanocrystals that are so small that they are not even visible under the microscope.

Researchers design engineered organ study the use of nanoparticles in breast cancer detection

Purdue University researchers have reproduced portions of the female breast in a tiny slide-sized model dubbed "breast on-a-chip" that will be used to test nanomedical approaches for the detection and treatment of breast cancer.

Bax factor that promotes cell death is also involved in regulating mitochondria behavior

New research led by UC Davis scientists provides insight into why some body organs are more susceptible to cell death than others and could eventually lead to advances in treating or preventing heart attack or stroke.

Small molecules may inhibit entry of Ebola into human cells

Ebola, a virus that causes deadly hemorrhagic fever in humans, has no known cure or vaccine. But a new study by University of Illinois at Chicago scientists has uncovered a family of small molecules which appear to bind to the virus's outer protein coat and may inhibit its entry into human cells.

Better understanding of rotational motion in living cells may help researchers study causes of deadly diseases

Advancements in understanding rotational motion in living cells may help researchers shed light on the causes of deadly diseases, such as Alzheimer's, according to Ning Fang, an associate scientist at the U.S. Department of Energy's Ames Laboratory and faculty member at Iowa State University.

Rice, BCM discovery addresses key roadblock to growing replacement tissues, organs

Researchers from Rice University and Baylor College of Medicine (BCM) have broken one of the major roadblocks on the path to growing transplantable tissue in the lab: They've found a way to grow the blood vessels and capillaries needed to keep tissues alive.

Nutriceuticals may restore age-related vision loss

While age-related vision loss of catastrophic proportions is predicted in coming decades, rising from 17 million patients today to 55 million by the year 2050, it's possible this catastrophe could be averted and lost vision even restored using molecular medicine.

Turns mortal heart attacks into non-mortal heart attacks -- NIH study

Three weeks of oral resveratrol or Longevinex- ingestion prior to an induced heart attack returned microRNA activity close to their pre-event levels in excised animal hearts. Among thousands of microRNA's studied, just six were attributed to exerting the majority of the gene-switching effects measured in the animal heart study - four microRNA optimally regulated by Longevinex- and two optimally by plain resveratrol.

Scientist discovers molecular switch controlling synthesis of ribosomes

A scientist from the Florida campus of The Scripps Research Institute has discovered a molecular switch that controls the synthesis of ribosomes. Ribosomes are the large machineries inside all living cells that produce proteins, the basic working units of any cell. These new findings offer a novel target for potential treatments for a range of diseases, including cancer.

Researchers develop new lung imaging technique that causes minimum tissue disruption

Fast-moving objects create blurry images in photography, and the same challenge exists when scientists observe cellular interactions within tissues constantly in motion, such as the breathing lung. In a recent UCSF-led study in mice, researchers developed a method to stabilize living lung tissue for imaging without disrupting the normal function of the organ.

Research on ribosome could aid antibiotic development against MRSA infection

Theoretical biologists at Los Alamos National Laboratory have used a New Mexico supercomputer to aid an international research team in untangling another mystery related to ribosomes-those enigmatic jumbles of molecules that are the protein factories of living cells.

Study of proteins under jam-packed conditions may open new treatment for diseases

People in a jetliner act and feel one way when crammed together like sardines in a can. But they have quite a different mindset when the middle seat is empty and they have more personal space. Scientists are pursuing a remarkable parallel that exists among the proteins involved in health and disease inside living cells.

Tension-dependent stabilization helps chromosome separation machinery

Scientists have discovered an amazingly simple way that cells stabilize their machinery for forcing apart chromosomes. Their findings are reported Nov. 25 in Nature.

Scientists uncover minute mechanism of nuclear pore complexes at molecular level

Dr. Joseph Glavy at Stevens Institute of Technology studies the smallest and most basic elements of life. The Assistant Professor of Chemical Biology runs the Glavy Lab, where advanced student scientists study the nuclear pore complexes (NPCs) in cells, observing the minutest mechanisms of life as they unfold during mitosis. The Glavy Lab's formal purpose is to study the NPC at the molecular level in the pursuit of the unknown or unexpected in the well-studied but not always well-understood nuclei of living cells.

Wave patterns formed from complex biochemical reactions can help identify diseased organs

By examining the distinct wave patterns formed from complex biochemical reactions within the human body, diseased organs may be more effectively identified, says Zhengdong Cheng, associate professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, who has developed a model that simulates how these wave patterns are generated.
