CHAMPAIGN, Ill. -- Underrepresented students' first-semester GPA may be a better predictor of whether they'll graduate college than their ACT score or their family's socioeconomic status, a new study found.

Researchers at the University of Illinois tracked the academic achievement and degree status of more than 1,900 U. of I. freshmen across a six-year period, beginning when the students first enrolled at the university in 2005 or 2006. The sample was selected to focus on students who were low-income, attended underresourced high schools and/or were historically underrepresented based on race or geography, and who could have completed an undergraduate program within six years.

Researchers at the University of Illinois at Chicago have discovered a molecular regulator that allows salmonella bacteria to switch from actively causing disease to lurking in a chronic but asymptomatic state called a biofilm.

Their findings are published in the online journal, eLife.

  • Conversely, nations that produce most greenhouse gases less vulnerable

  • Study shows "enormous global inequality" between emitters versus impacted nations
  • Countries like U.S., Canada, Russia, and China are climate "free riders," which dis-incentivizes mitigating their emissions
  • Problem will worsen in coming decades

    NEW YORK (EMBARGOED UNTIL FRIDAY, FEBRUAY 5TH 5:00 A.M. USET) - A new study by University of Queensland and WCS shows a dramatic global mismatch between nations producing the most greenhouse gases and the ones most vulnerable to the effects of climate change.

  • After evaluating content on idiopathic pulmonary fibrosis on almost 200 websites, researchers found that the information on Idiopathic Pulmonary Fibrosis
    (IPF) from these sites was often incomplete, inaccurate and outdated. 

    Doctors recommend several days of rest after a person suffers a concussion, but that is often good advice for many things. It works, but why? New data from animal models explains why.  

    Georgetown University Medical Center neuroscientists say rest allows the brain to reset neural networks and repair any short-term injury. The new study in mice also shows that repeated mild concussions with only a day to recover between injuries leads to mounting damage and brain inflammation that remains evident a year after injury.

    Why people lose their locks in old age may be related to the aging of hair follicle stem cells, two new studies suggest. Though it is known that mammals that live for longer lifespans lose their hair, the mechanisms underlying this fate have been a mystery. Hair follicle stem cells (HFSCs), which generate the sacs or follicles that produce hair, keep hair growth going repeatedly over time. Surprisingly, they have even been shown, in mice experiments, to resist aging. To better understand the role HFSCs might play in aging-associated hair loss, Hiroyuki Matsumura and colleagues studied hair follicles in a mouse model of accelerated hair loss.
