With the promising applications that carbon nanotubes might have for our daily lives, there exists the possibility that they may yet be harmful to us in some manner. Scientists at the Hopkins Bloomberg School of Public Health, School of Medicine, Department of Chemistry and Kennedy Krieger Institute have recently found that multiwalled carbon nanotubes, which are toxic, are not taken up by enterocytes, the absorptive cells lining your intestines.

Pink has long been the color of breast cancer awareness campaigns. Every October, during Breast Cancer Awareness Month, the pink ribbons, banners and advertisements are all intended to raise awareness about the disease that affects so many women around the globe. You are probably one of many who don the pink ribbon in October to show your support for the breast cancer cause.

Spinal digital subtraction angiography (SpDSA) is the leading medical imaging procedure for the precise evaluation of blood vessels surrounding the spinal cord. SpDSA is capable of diagnosing an array of spinal vascular disorders, including spinal cord stroke and spinal venous thrombosis. Despite its diagnostic value, SpDSA has a poor reputation when it comes to safety, and there have been reports of complications arising as a result of the procedure.

Hopkins researchers have found that 5-hydroxymethylcytosine (5hmC) content closely correlates with the differentiation state of cells. Terminally differentiated cells contain the highest levels of 5hmC, while less differentiated stem/progenitor cell compartments exhibit very low levels. In addition, 5hmC levels are significantly reduced in prostate, breast and colon carcinomas as compared to normal tissues, a finding which sheds some light on the characteristics that enable cancer cells to survive.

The Ebola virus, along with three of its close relatives, causes the Ebola hemorrhagic fever. Ever since the first Ebola outbreak occurred in 1976 in Yambuku, the virus has been considered one of the deadliest to affect humans, causing a very high fatality rate – up to 90 percent in some reported epidemics. There is no definitive treatment or vaccination for the Ebola virus, and, until recently, researchers were limited in their understanding of how the virus enters a host cell.

Researchers at the Hopkins Bloomberg School of Public Health have found that children in the Unites States exposed to secondhand tobacco smoke show an increase in blood lead levels. This is an additional hazard of tobacco smoke, which is already acknowledged widely as a major source of indoor air pollution. Exposure to secondhand smoke is responsible for several health problems in children including lower respiratory tract infections and reduced lung growth.

Researchers at Hopkins and Harvard have found that men using the cardiac drug digoxin had a 24 percent lower risk of developing prostate cancer. The group believes further studies may lead its use in treatment of the disease, which is the second largest cause of cancer-related deaths in U.S. men.

Astronomers have discovered one of the youngest galaxies in the distant universe. Containing stars that formed 13.5 billion years ago, merely 200 million years after the Big Bang, the finding addresses questions regarding the origins of the first galaxies and how the early universe evolved.

Hopkins scientists have found new evidence from studies in mice that shorter than normal telomeres, or “caps,” at the end of chromosomes may predispose people to age-related diabetes.

Researchers at Johns Hopkins are arguing for the reversal of the ban on transplanting HIV-infected organs and making them available to HIV-positive patients.

Geneticists have linked the differences in the physical appearance of humans and chimpanzees to the loss of certain genes in the five million years since we shared a common ancestor with the chimps.

Hopkins scientists have found that a virus that inserted itself into the human genome thousands of years ago may, in some cases, be responsible for amyotrophic lateral sclerosis (ALS).

On Feb. 6th, also known as Super Bowl Sunday, NASA’s twin STEREO probes moved into position on opposite sides of the sun, giving for the first time uninterrupted images of the entire star in three-dimensional action.

A team of researchers has found that the chances of survival following traumatic injury are greater in those who are insured than those who are uninsured.

A team of researchers from Hopkins and other universities has discovered that a genetic alteration in about one fourth of African Americans helps protect them from coronary artery disease, the leading cause of death among all Americans.

A Hopkins study has found that when it comes to food, we do appreciate something more if we have to make an effort to get it.

New findings by Hopkins researchers have revealed that pancreatic cancer develops and progresses much more slowly than scientists initially thought. This indicates that there is potentially a very broad window for screening, diagnosis and prevention of the deadly disease, which is the fourth greatest cause of cancer-related deaths in the United States.

In what was a great weekend for Hopkins cross country, the men finished in third place in the Centennial Conference championships on Saturday at the Patapsco Valley State Park in Elkridge, Maryland, while the women captured their third straight Centennial Conference title. The men, ranked sixth in the Mideast Region, totaled 95 points to take third place, finishing behind Dickinson (39) and Haverford, who placed first with 23 points.

Astronomers appear to have found the oldest galaxy in existence. The most distant object ever discovered lends support to astronomers’ model of the early universe, but also raises doubts over the source of the first light in space.

It was a mixed weekend for the Johns Hopkins water polo team, who won its two matches on Friday – against sixth-ranked Chapman and third-ranked Whittier, but then lost both their matches on the final day of the annual Claremont Convergence – understandably, though, as they were up against the two top-ranked teams in the nation in second-ranked Redlands and number-one Pomona-Pitzer. The team went 2-2 at the Convergence and sit at 9-9 overall.
