In preliminary experiments with mice and lab-grown cells, Johns Hopkins Kimmel Cancer Center scientists have found that a protein-signaling process accelerates the work of the gene most frequently mutated in a common form of adult leukemia and is likely necessary to bring about the full-blown disease.
A colorful Hubble telescope image of galaxy NGC 6503 shows bright red patches of gas scattered through its spiral arms, blue regions containing newly forming stars, and dark brown dust lanes snaking across its arms and center. The galaxy lies at the edge of what some astronomers call the Local Void.
On Sunday, June 7, 2015, ASHP, the national association representing pharmacists who serve as patient care providers in acute and ambulatory settings, approved a policy opposing pharmacists’ participation in capital punishment. It affirms that pharmacists’, as healthcare providers who are dedicated to achieving optimal health outcomes and preserving life, should not participate in capital punishment.
Scientists at Georgia State University (GSU) with funding from the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have designed an imaging technique to detect early-stage liver tumors, and have proven it successful in mice. Their study in an animal model is an essential step toward creating tools to improve liver tumor detection in human patients—whether primary liver cancer or metastatic tumors that arise in liver but have spread from other tissue.
A new study, published in the journal Chaos, suggests that unusually persistent spatial structures that self-assemble high in the atmosphere serve as “tracer patterns” around which atmospheric rivers grow. Based on simulations using real weather data in the Atlantic Ocean, the work was focused specifically on the transport of water from the Caribbean to the Iberian Peninsula, but it suggests a more general way to study the transport of tropical water vapor globally.
Materials melt faster when the lines of heat spread through the cold material like the branches of a tree -- and the melting rate can be steadily increased by allowing the tree architecture to freely evolve over time, researchers have discovered. The finding could help improve phase change energy storage systems, and could play an important role in ensuring a smooth flow of energy from renewable sources. The researchers report the results in the Journal of Applied Physics.

Dengue viruses are on the move. Spread among humans by mosquitoes, and across geographic boundaries through travel, the virus affects up to an estimated 390 million people every year around the world. In the U.S., recent outbreaks have occurred in Florida, Texas, Hawaii, and Puerto Rico. Scientists know one of the best ways to reduce the impact of the disease is to prepare healthcare providers by forecasting epidemics before they happen.
New technology developed by Howard Hughes Medical Institute (HHMI) researchers makes it possible to test for current and past infections with any known human virus by analyzing a single drop of a person's blood. The method, called VirScan, is an efficient alternative to existing diagnostics that test for specific viruses one at a time.
Terrorist attacks were responsible for the deaths of more than 2,977 individuals killed on Sept. 11, 2001, at the World Trade Center, the Pentagon, and in Shanksville, Pa., and 329 individuals (268 of them Canadian citizens) who lost their lives in the Air India Flight 182 bombing off the west coast of Ireland in 1985. Both attacks remain the worst acts of terrorism in the history of their respective countries. In a unique study examining the impact of terrorism related death on family bereavement, scientists from the Uniformed Services University of the Health Sciences (USU) Center for the Study of Traumatic Stress (CSTS), led by Dr. Stephen Cozza, will team with Voices of September 11th (VOICES) and the Canadian Resource Center for Victims of Crime (CRCVC) to research the impact of terrorism on surviving family members from these two attacks.

A team of researchers in China set out to design a cheaper material with properties similar to a graphene aerogel—in terms of its conductivity, as well as a lightweight, anticorrosive, porous structure. In the journal Applied Physics Letters, the researchers describe the new material they created and its performance.
Canadian researchers are studying the role that methane nanobubbles might play in the formation and dissociation of natural gas hydrates, a currently untapped source of natural gas and a chief energy source in the United States. Gaining a better understanding of how nanobubbles impact their formation and dissociation could help design procedures to more efficiently and safely harvest hydrates for natural gas capture. The findings are published this week in The Journal of Chemical Physics.
Working with a device that slightly resembles a microscopically tiny tuning fork, researchers at the University of Tsukuba in Japan have recently developed coupled microcantilevers that can make mass measurements on the order of nanograms with only a 1 percent margin of error -- potentially enabling the weighing of individual molecules in liquid environments. The findings are published this week in Applied Physics Letters.

Former Congressman Henry A. Waxman, one of the most accomplished legislators in the history of the U.S. Congress, joins the Johns Hopkins Bloomberg School of Public Health for the coming year as its Centennial Policy Scholar.
As countries prepare to finalize a climate agreement in Paris this coming December, global leaders like the United States and the European Union are releasing intended nationally determined contributions (INDCs), country specific action plans that outline how they intend to reduce global warming emissions. An analysis from the Union of Concerned Scientists (UCS) evaluated how the INDCs from the U.S., the EU and Mexico address land use emissions, which include those from agriculture and forestry. UCS found that the U.S. and EU INDCs fall short in describing what they will do to reduce land use emissions, but that Mexico’s contribution ambitiously addresses emissions from this sector.
The overall incidence rate for joint replacements among U.S. active component service members increased during an 11-year surveillance period, and service members in their 30s and early 40s are having the procedures more often and are remaining in the military longer after rehabilitation, according to a newly released health surveillance report.

In a head-to-head clinical trial comparing standard chemotherapy with the immunotherapy drug nivolumab, researchers found that people with squamous-non-small cell lung cancer who received nivolumab lived, on average, 3.2 months longer than those receiving chemotherapy. Squamous non-small cell lung cancer accounts for 25 to 30 percent of all lung malignancies.
In a report of a proof-of-principle study of patients with colon and other cancers for whom standard therapies failed, researchers at the Johns Hopkins Kimmel Cancer Center say that mistakes in so-called mismatch repair genes, first identified by Johns Hopkins and other scientists two decades ago, may accurately predict who will respond to certain immunotherapy drugs known as PD-1 inhibitors.
Simple measures of kidney function and damage may be just as good at predicting who is at risk for heart failure and death from heart attack and stroke as traditional tests of cholesterol levels and blood pressure, new Johns Hopkins Bloomberg School of Public Health-led research suggests.
Much like the automatic focus of a camera, our eyes and brains must constantly recalibrate so that we can get a clear view of the changing—and always moving—world around us. Two studies funded by the National Eye Institute (NEI) show how the circuitry for this eye-brain coordination is assembled during early embryonic development.
