15 emerging technologies that could reduce global catastrophic biological risks

11-Oct-2018 - Strategic investment in 15 promising technologies could help make the world better prepared and equipped to prevent future infectious disease outbreaks from becoming catastrophic events. This subset of emerging technologies and their potential application are the focus of a new report, ...

Computers outperform lab rats in detecting toxic chemicals

19-Feb-2018 - UL, the science safety company, and Johns Hopkins University have embarked on joint research that has resulted in findings that Artificial Intelligence (AI) is superior in finding toxic substances to traditional animal testing. Beyond being more effective, UL's Cheminformatics REACHAcross™ ...

Public health researchers map world's 'chemical landscape'

15-Feb-2016 - Researchers from the Johns Hopkins Bloomberg School of Public Health have created a map of the world's chemical landscape, a catalogue of 10,000 chemicals for which there is available safety data that they say can predict the toxicity of many of the 90,000 or more other substances in consumer ...

Reverse negative impact of ultraviolet radiation on skin

05-Aug-2015 - Over time, the sun's ultraviolet (UV) light damages the fibers in the skin called elastin. When these fibers break down, the skin begins to sag, stretch, and lose its ability to go back into place after stretching. The skin also bruises and tears more easily. The result: premature wrinkles, ...

Digoxin may be a possible treatment for prostate cancer

05-Apr-2011 - Scientists have identified digoxin as a possible therapy for prostate cancer, using a combination of laboratory science and epidemiology that is unprecedented in its cooperative nature. "Epidemiologists and basic scientists often do not understand each other, as we often are only clear on our ...

Keeping stem cells from changing fates

13-Sep-2010 - Johns Hopkins researchers have determined why certain stem cells are able to stay stem cells. The report in Cell Stem Cell reveals that an enzyme that changes the way DNA is packaged in cells allows specific genes to be turned on and off, thereby preventing a stem cell from becoming another cell ...

Agilent Technologies and Johns Hopkins University to Research Toxicity Pathways for Embryonic Brain Development

20-Aug-2010 - Agilent Technologies Inc. and the Agilent Foundation announced that Dr. Thomas Hartung has received an Agilent Thought Leader Award in support of his research for the use of toxicity pathways to predict developmental neurotoxicity. This work could help identify possible contributions of ...

Scientists map epigenetic changes during blood cell differentiation

Potential application for stem cell therapies

17-Aug-2010 - Having charted the occurrence of a common chemical change that takes place while stem cells decide their fates and progress from precursor to progeny, a Johns Hopkins-led team of scientists has produced the first-ever epigenetic landscape map for tissue differentiation. The details of this ...

Scientists Identify DNA That May Contribute to Each Person's Uniqueness

11-Aug-2010 - Building on a tool that they developed in yeast four years ago, researchers at the Johns Hopkins University School of Medicine scanned the human genome and discovered what they believe is the reason people have such a variety of physical traits and disease risks. In a report published in Cell, ...

Biomarkers help predict prostate cancer progression

21-Apr-2010 - Researchers at Johns Hopkins have evaluated a simple, more specific blood test that identifies patients undergoing proactive surveillance for low-grade, low-stage, non-palpable prostate cancer who would eventually require treatment. These results, presented at the American Association for Cancer ...
