Malaria parasite lives on the edge

The parasite that causes malaria expresses genes that code for the proteins it will need in later life stages, using two separate schemes to prevent these proteins from actually being made until they are needed, according to new research.

One avocado a day helps lower 'bad' cholesterol for heart healthy benefits

Move over, apples — new research from Penn State suggests that eating one avocado a day may help keep “bad cholesterol” at bay. According to the researchers, bad cholesterol can refer to both oxidized low-density lipoprotein (LDL) and small, dense LDL particles.

Paper by MCIBS Grad Laura Bennett Inspires Journal Cover

Laura Bennett's investigation into the effects of inflammation, done with advisor Robert Paulson, was featured on the cover of Science Signaling last month.

Professor of Biomedical Engineering Deb Kelly hopes to 'outsmart breast cancer'

October is National Breast Cancer Awareness Month. One of the pioneering researchers in the fight against breast cancer is Deb Kelly, professor of biomedical engineering and director of the Center for Structural Oncology at Penn State.

Liquid-Cell Electron Tomography (LC-ET) offers an exciting technical advance to study dynamic materials in solution. The figure illustrates how LC-ET was used to define the “rules of engagement” for pathogenic phages and its host bacterium. IMAGE: KELLY LAB/PENN STATE

Scientists have first 3D view of life's processes in liquid

A new liquid-cell technology allows scientists to see living biological materials and systems in three dimensions under an electron microscope, according to researchers at Penn State, Virginia Tech and Protochips Inc.

Melissa Rolls appointed Paul Berg Professor of Biochemistry

Melissa Rolls, professor of biochemistry and molecular biology, has been named the Paul Berg Professor of Biochemistry. The professorship was created in 1995 by an anonymous donor in honor of Paul Berg, a 1948 Penn State graduate who was named a Distinguished Alumnus in 1974 and earned the Nobel Prize in 1980 for developing a method to map the structure and function of DNA.

Penn State researchers receive grant to explore novel method of anticoagulation

Two Penn State biomedical engineering faculty members have received a two-year, $200,000 grant from the American Heart Association (AHA) to explore potential solutions to thrombosis, or blood clot formation, a prevalent issue with blood-contacting medical devices such as heart valves, blood pumps and cardiac stents.

Virus may jump species through 'rock-and-roll' motion with receptors

Like a janitor thumbing through a keychain to find just the right key to open a lock, the "rock-and-roll" motion of the canine parvovirus during the binding process may help explain how the virus can find the spot on a receptor to infect not just dogs, but multiple species, according to an international team of researchers.

New tool in fight against malaria

Redesigning molecules originally developed to treat the skin disease psoriasis could lead to an effective new drug against malaria, according to an international team of researchers.

Gene therapy helps functional recovery after stroke

A new gene therapy turns glial cells—abundant support cells in the brain—into neurons, repairing damage that results from stroke and significantly improving motor function in mice.
