Study indicates underlying molecular sources in COVID-19 variability

Humans have different susceptibilities to SARS-CoV-2, and eventually develop varying degrees of fatigue, fever, and breathing problems.

Research demonstrates an agriculturally amenable epigenetic breeding method

Novel grafted plants -- consisting of rootstock epigenetically modified to "believe" it has been under stress -- joined to an unmodified scion, or above-ground shoot, give rise to progeny that are more vigorous, productive and resilient than the parental plants.

Researchers develop "mini lungs" to study SARS-CoV-2 infection

'Mini-lungs' grown from tissue donated to Cambridge hospitals has provided a team of scientists from South Korea and the UK with important insights into how COVID-19 damages the lungs.

Genomic differences can help develop more personalized treatments for African American men

Prostate cancer is the most common type of cancer among American men after skin cancer, but the disease does not affect all races equally.

Study raises ethical concerns about gene-editing technologies

Genome editing of human embryos represents one of the most contentious potential scientific applications today. But what if geneticists could sidestep the controversy by editing sperm and eggs instead?

New DNA-cutting tool could advance gene editing for novel treatments

Gene editing for the development of new treatments, and for studying disease as well as normal function in humans and other organisms, may advance more quickly with a new tool for cutting larger pieces of DNA out of a cell's genome, according to a new study by UC San Francisco scientists.

First-ever draft sequence of the human proteome mapped successfully

Two decades after the release of the human genome, researchers have mapped the first-ever draft sequence of the human proteome.

Researchers discover a gene responsible for urination

In a National Institutes of Health (NIH)-funded study involving both mice and patients who are part of an NIH Clinical Center trial, researchers discovered that a gene, called PIEZO2, may be responsible for the powerful urge to urinate that we normally feel several times a day.

Rutgers researchers discover gene markers linked to metastatic prostate cancer

Rutgers researchers have discovered human gene markers that work together to cause metastatic prostate cancer - cancer that spreads beyond the prostate.

Researchers develop new method to advance wildlife genomics

A team of scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW), the Australian Museum, and the Max Delbrück Center for Molecular Medicine (MDC) report a new method for identifying any genome sequence located next to a known sequence.

Researchers develop new approach that uses DNA-synthesizing biological enzyme

According to current estimates, the amount of data produced by humans and machines is rising at an exponential rate, with the digital universe doubling in size every two years.

Researchers identify “silent” mutations in the genetic code of COVID-19 virus

We know that the coronavirus behind the COVID-19 crisis lived harmlessly in bats and other wildlife before it jumped the species barrier and spilled over to humans.

Study offers renewed hope for children suffering from myofibrillar myopathies

Stephen Greenspan and Laura Zah were devastated when they learned their son Alexander had a rare genetic mutation, which causes a deadly neuromuscular disease with no known treatment or cure.

Study sheds light on whether corals are genetically equipped to handle warmer oceans

In 1998, ocean temperatures soared, and the world experienced its first significant coral bleaching event. From the Great Barrier Reef to Indonesia to Central America, corals turned white and ghostly.

DNA structural changes play key role in the recovery phase after DNA damage

A research team from Cologne has discovered that a change in the DNA structure - more precisely in the chromatin - plays a decisive role in the recovery phase after DNA damage. The key is a double occupation by two methyl groups on the DNA packaging protein histone H3 (H3K4me2).
