Genetics and Genomics

Several recent science articles focus on new discoveries that bring forth concerns about old bacteria causing many deaths in the past could lead to new bacteria that may cause future outbreaks. Researchers have found tiny bits of DNA in the teeth of two German victims of the Justinian plague from around 1,500 years ago. Scientists...

It has long been an accepted theory among paleontologists that the Americas were first populated by nomadic tribes of hunter-gatherers who emigrated from the far east of Asia during the last Ice Age nearly 15,000 years ago.  With ocean levels reduced worldwide because of glaciations drawing a vast portion of water into the ice, a...

After the sequencing of the human genome a decade ago, hopes of massive discoveries of new drugs to treat all types of diseases fell short. Now, a partnership between an up-and-coming biotechnology company, Regeneron, and the Geisinger Health System in Pennsylvania is generating new hope and a great deal of excitement, with their plans to...

Racial disparities in health are well-documented, predicting a shorter life expectancy and an increased risk of age-related illnesses at younger ages for African Americans, in comparison to those in whites. Now, a new study shows that there may be a link between accelerated aging at the biological level to the impact that racism has on...

A science article printed in the science journal, Nature Communications, possibly explains why some people consume large amounts of alcohol while others do not. In a study performed on mice, a consortium of researchers from five UK universities found that a mutation to the gene Gabrb1 resulted in mice having an overwhelming preference to drink...

The bacterium staphylococcus aureus, commonly referred to as MRSA, has been deemed a “superbug” because of its resistance to antibiotics. Affecting 1 million Americans every year, MRSA causes serious infections of the bone, heart, and implanted medical devices. Due to the inability of the bacterium to be effectively treated and the seriousness of the deep-seated...

Fingerprints have long provided a method used for law enforcement to learn who was guilty of crimes. Now, fingerprinting technology has been improved. Adding a fluorescent product to directly highlight fingerprints makes it faster, easier and less expensive to gather fingerprint evidence. The discovery made by the French Police and Gendarmerie, in combination with the FBI...

Hair loss is a common problem for both men and women, especially those over the age of 50. While some experience uniform thinning of their hair, others may have spots or complete baldness. In spite of new medications and treatment methods that have been developed, little success has been found in preventing or reversing balding....

The fact that white men are more susceptible to testicular cancer has long been known. Now, researchers have made a discovery that may explain this differentiation. A genetic variant known to put men at an increased risk of developing the cancer plays a role in protecting fair-skinned men from the ultraviolet rays of the sun. A...
