DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Researchers propose a new statistical method for analyzing the genetic admixture of populations

Researchers of the HSE International Laboratory of Statistical and Computational Genomics together with their international colleagues have proposed a new statistical method for analysing population admixture that makes it possible to determine the time and number of migration waves more accurately.

Scientists receive $3.9 million NIH grant to eradicate HIV from the brain

Finding a cure for HIV has been extremely difficult, in part because the virus hides from antiretroviral treatments in one of the hardest places to reach: the brain.

Innovative technology reveals new insights into cellular reservoirs of HIV

In a presentation today at AIDS 2022, the 24th International AIDS Conference in Montreal, scientists with the National Institute of Allergy and Infectious Diseases' (NIAID) Vaccine Research Center (VRC) and their collaborators described how their use of cutting-edge technology revealed new insights into cellular reservoirs of HIV and what those observations could mean for the next steps in HIV cure research. NIAID is part of the National Institutes of Health.

Researchers pinpoint multiple zoonotic origins of SARS-CoV-2

In a pair of related studies, published July 26, 2022 online via First Release in Science, researchers at University of California San Diego, with colleagues on four continents, show that the origin of the COVID-19 pandemic in 2019 was at the Huanan Seafood Wholesale Market in Wuhan, China, and resulted from at least two instances of the SARS-CoV-2 virus jumping from live animal hosts to humans working or shopping there.

Researchers develop new kind of Atomic Force Microscopy probes in true 3D shapes

A team of researchers from NYU Abu Dhabi's Advanced Microfluidics and Microdevices Laboratory (AMMLab) have developed new kind of Atomic Force Microscopy (AFM) probes in true three-dimensional shapes they call 3DTIPs. AFM technology allows scientists to observe, measure, and manipulate samples and micro and nanoscale entities with unprecedented precision.

Scientists discover a surprising link between mitochondria, inflammation and DNMT3A and TET2 genes

Mitochondria are known as cells' powerhouses, but mounting evidence suggests they also play a role in inflammation. Scientists from the Salk Institute and UC San Diego published new findings in Immunity on July 26, 2022, where they examined human blood cells and discovered a surprising link between mitochondria, inflammation and DNMT3A and TET2 - two genes that normally help regulate blood cell growth but, when mutated, are associated with an increased risk of atherosclerosis.

Elevated insulin resistance, advanced cell aging associated with childhood poverty

Black adolescents who lived in poverty and were less optimistic about the future showed accelerated aging in their immune cells and were more likely to have elevated insulin resistance at ages 25-29, researchers found.

Using CRISPR technology to successfully prevent and treat SARS-CoV-2 infections

In what is believed to be a first, a research team led by Duke Health has demonstrated a way to use CRISPR technology to successfully prevent and treat COVID infections.

New RT-PCR platform gives results faster than other COVID-19 tests on the market

For more than 30 years, polymerase chain reaction (PCR) has been the gold standard in molecular diagnostic testing, detecting genetic material, such as those from a virus or from human DNA.

25 Jul 2022

Study identifies risks in the use of CRISPR therapeutics

The researchers caution: "The CRISPR genome editing method is very effective, but not always safe. Sometimes cleaved chromosomes do not recover and genomic stability is compromised - which in the long run might promote cancer."

A different approach to build a more durable, broadly effective COVID-19 vaccine

Researchers at University of California San Diego School of Medicine, with colleagues elsewhere, describe a different way to build a COVID-19 vaccine, one that would, in theory, remain effective against new and emerging variants and could be taken as a pill, by inhalation or other delivery methods.
