After months of delayed, fragmented responses, the international medical community recognized Ebola as a threat to global health security. Here’s where the situation stands today as well as questions raised and lessons learned.
“Berlin Patient” Timothy Brown was cured of HIV after he received stem cells from a naturally immune patient. His story inspired two companies to try and recreate that natural immunity in HIV patients using stem cells and cutting-edge gene-editing. Now Harvard has joined the race.
Scientists have sequenced the mitochondrial genome in glaucoma patients to help further understanding into the genetic basis for the disease. Glaucoma is a major cause of irreversible blindness, affecting more than 60 million people worldwide.
For hibernating mammals, the pre-winter months are a race against time to accumulate enough energy reserves to last until spring. Offspring born late in the year have much less time to achieve this. New research shows that power-napping can help late-born garden dormice overcome these unfavorable odds.
Researchers say they have identified first steps in the origin of pancreatic cancer and that their findings suggest preventive strategies to explore. In a new study, the scientists described the molecular steps necessary for acinar cells in the pancreas to become precancerous lesions.
The United States Monday opened the first of 17 Ebola treatment units it is building in Liberia. The new clinic opened in Tubmanburg, about 60 kilometers (40 miles) north of the capital, Monrovia.
A research team has used whole genome sequencing to identify a new genetic cause of a severe, rare and complex form of epilepsy that becomes evident in early childhood and can lead to early death.
A major breakthrough in the development of stem cell-derived brain cells has put researchers on a firm path towards the first-ever stem cell transplantations in people with Parkinson’s disease.
Bacteria in colonies don’t reproduce sexually and are genetically identical, yet they can prepare in advance for changing environmental conditions. Researchers have shown that bacteria carry out this strategy by producing cells with differing amounts of specific proteins that govern their response to chemical signals.
Most cancer deaths occur because of metastasis, yet progress in preventing and treating migratory cancer cells has been slow. Scientists have now identified a cellular culprit that should help researchers better understand how metastasis begins.
As the biggest-ever outbreak of Ebola continues to ravage West Africa, here are a few key numbers to get a handle on the epidemic.
The nasal spray version of the flu vaccine did not protect young children against swine flu last winter and might not work again this year, health officials said Thursday.
Ebola and Marburg are 16 to 23 million years old, not thousands of years old as once thought, according to a new study. The research also indicates that while Ebola and Marburg diverged from each other millions of years ago.
For years, a multidisciplinary research team has tracked an elusive creature, a complex of proteins thought to be at fault in some cases of sudden cardiac death. Now, they have finally captured images of the complex.
Scientists have found a new way to forecast which patients with age-related macular degeneration are likely to suffer from the most debilitating form of the disease.
Scientists have identified chemicals found in some everyday fruit that could protect vital organs from long-term damage following a heart attack or stroke, according to new research.
Researchers have identified a small protein with a big role in lowering plasma glucose and increasing insulin sensitivity. The report indicates that Sestrin 3 plays a critical role in regulating molecular pathways that control the production of glucose and insulin sensitivity in the liver.
Researchers are building an entire technology around tiny, microscopic bubbles– a technology that has the potential to play an important role in diagnosing as well as treating disease like stroke and cancer.
Researchers have successfully replicated a direct brain-to-brain connection between pairs of people as part of a scientific study following the team’s initial demonstration a year ago.
Asthma may be more harmful than was previously thought, according to researchers who found that genetic damage is present in circulating, or peripheral, blood.
Although gluten-free foods are trendy among the health-conscious, they are necessary for those with celiac disease. But gluten, the primary trigger for health problems in these patients, may not be the only culprit.
Genetically engineering tumors in mice, a technique that has dominated cancer research for decades, may not replicate important features of cancers caused by exposure to environmental carcinogens, according to a new study.
A multicenter team of researchers has identified an enzyme key to the survival and spread of glioblastoma cancer cells that is not present in healthy brain cells, making the enzyme a promising therapeutic target.
The current Ebola outbreak shows how quickly diseases can spread with global jet travel. Yet knowing how to predict the spread of these epidemics is still uncertain, because the complicated models used are not fully understood, according to scientists.
The Ebola outbreak has spawned a "silent killer," experts say: hidden cases of malaria, pneumonia, typhoid and the like that are going untreated because people in the countries hardest hit by the dreaded virus either cannot find an open clinic or are too afraid to go to one.
