Controlled, localized delivery of blood thinner may improve blood clot treatment
Researchers combined heparin with a protein fragment, peptide, to slow down the release of the drug and convey the medication directly to the site of a clot.
Physicists model cell migration to learn how cancer cells navigate tissue
This migration mode is one of the ways cancer cells navigate tissue during metastasis. In a new study researchers have explored mesenchymal migration through cell simulations and mathematical modeling. Their aim: to learn more about how cancer cells si…
Now on the molecular scale: Electric motors
Electric vehicles, powered by macroscopic electric motors, are increasingly prevalent on our streets and highways. Now a multidisciplinary team has made an electric motor you can’t see with the naked eye: an electric motor on the molecular scale. This …
Researchers create an optical tractor beam that pulls macroscopic objects
Researchers demonstrated a new type of optical manipulation: using laser light to pull a macroscopic object. The technology has potential for applications in the continued explorations of Mars.
New levers for controlling plant biochemistry
Plant biochemists have discovered a new level of regulation in the biochemical ‘machinery’ that plants use to convert organic carbon derived from photosynthesis into a range of ring-shaped aromatic molecules. The research suggests new strategies for co…
Some hospitalized patients’ infections may develop from their own bacteria
The opportunistic bacterium Acinetobacter baumannii rarely sickens healthy people but causes serious infections in hospitalized patients. A study in mice suggests that Acinetobacter can hide undetected in bladder cells and then reactivate when stimulat…
Researchers take key step toward new treatment for hereditary blindness
Scientists have demonstrated in animal models the possibility of using lipid nanoparticles and messenger RNA, the technology underpinning COVID-19 vaccines, to treat blindness associated with a rare genetic condition.
CAR T cell therapy may eliminate tumor cells missed by surgery
CAR T cell therapy may enhance the effectiveness surgery for of solid tumors, according to a preclinical study.
Research team builds framework to quantify brain’s control costs
The brain performs various cognitive and behavioral functions in everyday life, flexibly transitioning to various states to carry out these functions. Scientists view the brain as a system that performs these numerous functions by controlling its state…

Researchers uncover mechanisms to easily dry, redisperse cellulose nanocrystals
A team of chemical engineering researchers studied the mechanisms of drying the nanocrystals and proposed nanotechnology to render the nanocrystals highly redispersible in aqueous mediums, while retaining their full functionality, to make them easier t…
Discovery of metabolic switch could lead to targeted treatment of obesity, cancer
Researchers have discovered how to modify the function of an enzyme crucial to fat production in fruit flies, which could lead to more effective treatments of cancer and childhood obesity in humans.
Developing mucosal vaccines for respiratory viruses
Vaccines that provide long-lasting protection against influenza, coronaviruses and respiratory syncytial virus (RSV) have proved exceptionally difficult to develop. Researchers now explore the challenges and outline approaches to improved vaccines.
