Geologists seek answers with largest deployment of seismometers along Alaskan Peninsula

  ITHACA, N.Y. – Using a fleet of airplanes, ships and intrepid scientists, Cornell is leading the largest single deployment of seismometers along the Alaskan Peninsula – a $4.5 million endeavor that geologists from across the country hope will solve long-standing mysteries about the region and the planet. “This is something I’ve wanted to see […]

Fast, efficient sperm tails inspire nanobiotechnology

Just like workers in a factory, enzymes can create a final product more efficiently if they are stuck together in one place and pass the raw material from enzyme to enzyme, assembly line-style. That’s according to scientists at Cornell’s Baker Institute for Animal Health, the first team to recreate a 10-step biological pathway with all […]

New findings on embryonic heart valves may prevent congenital heart defects in newborns

ITHACA, N.Y. – Cornell biomedical engineers have discovered natural triggers that could reduce the chance of life-threatening, congenital heart defects among newborn infants. Those triggers can override developmental, biological miscues, leading to proper embryonic heart and valve formation. More than 40,000 babies in the United States – or about 1 in 100 births – are […]

Stiffer breast tissue in obese women promotes tumors

ITHACA, N.Y. – Women who are obese have a higher risk and a worse prognosis for breast cancer, but the reasons why remain unclear. A Cornell study published this month in Science Translational Medicine explains how obesity changes the consistency of breast tissue in ways that are similar to tumors, thereby promoting disease.   Media […]

New device isolates most aggressive cancer cells

ITHACA, N.Y. – Not all cancer cells are created equal – some stay put in the primary tumor, while others move and invade elsewhere. A major goal for cancer research is predicting which cells will metastasize, and why. A Cornell cancer research team is taking a new approach to screening for these dangerous cells, using […]

Found: A gene family that suppresses prostate cancer

ITHACA, N.Y. – Cornell University researchers report they have discovered direct genetic evidence that a family of genes, called MicroRNA-34 (miR-34), are bona fide tumor suppressors. The study is published in the journal Cell Reports, March 13. Previous research at Cornell and elsewhere has shown that another gene, called p53, acts to positively regulate miR-34. […]
