Environmental DNA provides a wealth of information for conservationists, archaeologists and forensic scientists. But the unintentional pickup of human genetic information raises ethical questions.
Prokaryotes are single-celled organisms without nuclei and are commonly known as bacteria.

Financial support for science and research in Nigeria remains pathetic. This has led to the deterioration in the quantity and quality of trained virologists at universities.
Ethical and equitable scientific collaboration could help increase the genetic diversity of genomic data.

Existing genetic data and sequencing tools are overwhelmingly based on people of European ancestry, which excludes much of the rich genetic variation of the world.
Even when much course instruction moved online due to COVID-19, some wet lab courses have continued in-person since summer 2020.

A medical genomics professor reflects on how lab simulations offer some advantages for student learning, but developing the muscle memory of performing hands-on lab work is important.
Revolutions in genome sequencing have been used to track COVID-19 in near real time.
Sequencing the genome of a virus gives researchers information on how mutations can affect its transmissibility and virulence.

Genomic sequencing of positive COVID-19 samples could help New Zealand pinpoint the source of its new community outbreak. But it only works if all samples are sequenced – and right now, they’re not.
Studying the genomes of mountain goats supports conservation efforts.

As mountain goats face pressures from climate change and human disturbance, analyzing their genome provides useful information on their ecology and evolution.
On a family camping trip over the Australia Day long weekend, I sat in a tent with my laptop, designing New South Wales’ first genomic sequencing test for COVID-19.
Pancreatic cancer has historically had among the lowest survival rates of any type of cancer. A recent study that looked at genomic changes reveals some possible clues.

DNA sequencing means a scientist can take a bucket of seawater and ID every fish in the area. Now we need a universal ‘biobank’ of samples to make a truly powerful environment monitoring tool.
In 2030, some diseases are defined more specifically than in the past with a focus on their molecular makeup. This is known as precision medicine.

In 2030, there is a boom in precision medicine, where diseases – from cancer to dementia – are defined and targeted more specifically with a focus on their molecular makeup.
The rise of personalised medicine, which is mainly based on genetic testing, needs adequate regulation so privacy rights aren’t breached. That’s only one of several issues that must be considered.
