Stemlike cells at tumor perimeter promote new blood vessels to feed tumor growth

Stemlike cells at the edge of melanoma tumors secrete factors to promote blood-vessel growth, allowing the cancer to grow and spread.

Scientists: Expanding Brazilian sugarcane could dent global CO2 emissions

Vastly expanding sugarcane production in Brazil for conversion to ethanol could reduce current global carbon dioxide emissions by as much as 5.6 percent, researchers report in the journal Nature Climate Change.

Illinois sportfish recovery a result of 1972 Clean Water Act, scientists report

Populations of largemouth bass, bluegill, catfish and other sportfish are at the highest levels recorded in more than a century in the Illinois River, according to a new report. Their dramatic recovery, from populations close to zero near Chicago throughout much of the 20th century, began just after implementation of the Clean Water Act, the researchers say.

Report identifies factors associated with harassment, abuse in academic fieldwork

College students considering careers in fields like archaeology or geology that require extensive work at remote field sites might want to find out how potential supervisors and advisers conduct themselves in the field. Do they establish clear ground rules for the behavior of everyone on the team? Are the rules consistently enforced? According to a new report, such factors likely influence whether students will witness or experience harassment while working far from home.

Mantis shrimp-inspired camera enables glimpse into hidden world

By mimicking the eye of the mantis shrimp, Illinois researchers have developed an ultra-sensitive camera capable of sensing both color and polarization. The bioinspired imager can potentially improve early cancer detection and help provide a new understanding of underwater phenomena, the researchers said.

Cholesterol byproduct hijacks immune cells, lets breast cancer spread

A cholesterol byproduct facilitates breast cancer’s spread by hijacking immune cells, a new University of Illinois study found.

Some plants grow bigger – and meaner – when clipped, study finds

Some plants behave like the mythical monster Hydra: Cut off their heads and they grow back, bigger and better than before. A new study finds that these “overcompensators,” as they are called, also augment their defensive chemistry – think plant venom – when they are clipped.

No ‘narcissism epidemic’ among college students, study finds

Today’s college students are slightly less narcissistic than their counterparts were in the 1990s, researchers report in a new study – not significantly more, as some have proposed. The study, reported in the journal Psychological Science, analyzed data from 1,166 students at the University of California, Berkeley in the 1990s, and from tens of thousands of students at the University of Illinois at Urbana-Champaign and the University of California, Davis in the 2000s and 2010s.

Antibiotic-resistant infections in pets: What now?

Rates of antibiotic-resistant infections in companion animals are rising at an alarming rate. An Illinois veterinarian discusses what can be done about it.

Large, crystalline lipid scaffolds bring new possibilities to protein, drug research

Proteins and drugs are often attached to lipids to promote crystallization or ensure delivery to targeted tissues within the body, but only the smallest proteins and molecules fit within these fat structures. A new study reveals a lipid structure that can support much larger proteins and molecules than before, potentially increasing the variety of drugs that can be attached to these fat molecules.
