‘Molecular prosthetics’ can replace missing proteins to treat disease

Researchers have demonstrated that a small molecule can transport iron in human cells and live animals when proteins that normally do the same job are missing, a condition that often causes severe anemia in patients. Such “molecular prosthetics” might treat a host of incurable diseases caused by protein deficiencies, such as anemias, cystic fibrosis or certain types of heart disease.

Antibiotic breakthrough: Team discovers how to overcome gram-negative bacterial defenses

Scientists report that they now know how to build a molecular Trojan horse that can penetrate gram-negative bacteria, solving a problem that for decades has stalled the development of effective new antibiotics against these increasingly drug-resistant microbes. The findings appear in the journal Nature.

Report: Even in death, indigenous border crossers marginalized

Of the hundreds of people who die trying to cross into the U.S. from Mexico each year, those with indigenous backgrounds are less likely to be identified than those with more European ancestry, a new analysis reveals.

Anemonefish dads further fathering research

Like the dad in “Finding Nemo,” anemonefish fathers will do almost anything to support their offspring. Their parenting instincts are so strong that if you give a bachelor anemonefish a scoop of anemonefish eggs from an unrelated nest, he will care for them – constantly nipping at them to remove debris and fanning them with oxygen-rich waters – as if they were his own. (Any other fish would eat them, researchers say.)

Team discovers a new invasive clam in the U.S.

A new invasive clam has made its official debut in North America.

Study offers new insight into powerful inflammatory regulator

A new study in mice reveals how a protein called Brd4 boosts the inflammatory response – for better and for worse, depending on the ailment. The study is the first to show that this protein, while problematic in some circumstances, also can protect the body from infection.

Brain tissue structure could explain link between fitness and memory

Studies have suggested a link between fitness and memory, but researchers have struggled to find the mechanism that links them. A new study by University of Illinois researchers found that the key may lie in the microstructure of the hippocampus, a region in the middle of the brain involved in memory processes.

Science at Illinois feeds the world, furthers health, protects the planet

Illinois scientists are helping power plants run more efficiently, designing better, longer-lasting batteries, finding new ways to target cancerous tumors, and developing robots that can aid in construction, in agricultural fields and even inside the human body.

Study links brain structure, anxiety and negative bias in healthy adults

Healthy college students who have a relatively small inferior frontal cortex – a brain region behind the temples that helps regulate thoughts and emotions – are more likely than others to suffer from anxiety, a new study finds. They also tend to view neutral or even positive events in a negative light, researchers report.

Nanopores could map small changes in DNA that signal big shifts in cancer

Detecting cancer early, just as changes are beginning in DNA, could enhance diagnosis and treatment as well as further our understanding of the disease. A new study by University of Illinois researchers describes a method to detect, count and map tiny additions to DNA called methylations, which can be a warning sign of cancer, with unprecedented resolution.
