Changed gene expression after heart surgery extends cardiomyocyte regeneration – BIOENGINEER.ORG

BIRMINGHAM, Ala. – While lower vertebrates can repair their adult hearts after a heart attack, mammals – including humans – cannot. The ability to regenerate dead muscle tissue in mammalian hearts disappears just a few days after birth because the heart muscle cells, called cardiomyocytes, exit the cell cycle. BIRMINGHAM, Ala. – While lower vertebrates … Read more

Arsenic in private well water contributes to low birth weight even at low levels – BIOENGINEER.ORG

In the largest epidemiologic study of arsenic and birth outcomes to date, researchers from the University of Illinois Chicago and collaborating institutions estimated arsenic levels in US private well water sources by county and compared estimates to documented birth outcomes. They found an association between estimated groundwater arsenic concentration and risk of low birth weight. … Read more

Novel sewage treatment system removes up to 70% of nitrogen that would otherwise be discarded into nature – BIOENGINEER.ORG

A new type of biofilm reactor adapted to Brazilian conditions and using polyurethane foam to lower costs can reduce the amount of nitrogen compounds in wastewater by as much as 70%, according to an article in Environmental Technology. The researchers who conducted the study developed a mathematical model to analyze and predict the nitrogen removal … Read more

Microscopy technique enables 3D super-resolution nanometre-scale imaging – BIOENGINEER.ORG

Over the last two decades, microscopy has seen unprecedented advances in speed and resolution. However, cellular structures are essentially three-dimensional, and conventional super-resolution techniques often lack the necessary resolution in all three directions to capture details at a nanometer scale. A research team led by Göttingen University, including the University of Würzburg and the Center … Read more

When looking at the future of production of micro-scale organic electronics, Mohammad Reza Abidian – associate professor of Biomedical Engineering at the University of Houston Cullen College of Engineering – sees their potential for use in flexible electronics and bioelectronics, via multiphoton 3-D printers . When looking at the future of production of micro-scale organic … Read more

Seismic waves from earthquakes reveal changes in the Earth’s outer core – BIOENGINEER.ORG

In May 1997, a large earthquake shook the Kermadec Islands region in the South Pacific Ocean. A little over 20 years later, in September 2018, a second big earthquake hit the same location, its waves of seismic energy emanating from the same region. Credit: Virginia Tech’s Ying Zhou.

Oral antiviral drug effective against respiratory syncytial virus (RSV) identified by Biomedical Sciences researchers – BIOENGINEER.ORG

ATLANTA — An oral antiviral drug that targets a key part of the respiratory syncytial virus (RSV) polymerase and inhibits the synthesis of viral genetic material has been identified, a finding that could provide an effective treatment against RSV disease, according to researchers at the Center for Translational Antiviral Research at Georgia State University. ATLANTA … Read more

5 misunderstandings of pregnancy biology that cloud the abortion debate

On June 24, the U.S. Supreme Court overturned Roe v. Wade. By undoing the landmark 1973 decision that protected a person’s right to an abortion, the highest court in the country has shifted decisions about this medical care to individual state and local governments. Some states have already passed laws that curtail abortion access. Now, … Read more
