Malaysian farmers, environmental groups call for rejection of GMO rice trial
A coalition of farmers, consumer associations and environmental groups is urging Malaysia's National Biosafety Board to reject a proposed field trial of genetically modified rice, warning Tuesday the project could pose risks to food safety, the environment and farmers.
Genetic variants shed light on kidney transplant rejection
Immunosuppressive medications help prevent organ rejection following transplantation, yet some patients still experience rejection despite receiving adequate treatment.
Humans have a 'highly abundant' number of stable proteins that are not all predicted by genetic code
In 1968, the American biochemist and geneticist Marshall Nirenberg and his colleagues won the Nobel Prize in physiology or medicine for their work deciphering how an organism's proteins are directly linked to its genetic code.
Long before adulthood, a chemical mark may quietly shape how the brain handles stress
Stress or trauma during childhood may leave people more vulnerable to mental health struggles and stress later in life. Scientists think one reason could be that early-life stress leaves lasting molecular bookmarks on DNA, without changing the genetic sequence itself. A recent st
Historical DNA reveals largetooth sawfish have lost much of their genetic diversity
The genetic diversity of the largetooth sawfish (Pristis pristis), a critically endangered ray, has plummeted over the past century and a half, according to a study published in the Proceedings of the Royal Society B: Biological Sciences.
How barramundi research gives breeders more control
Barramundi farmers will soon be able to improve stock genetics by placing more emphasis on the sex of their breeding fish.
New species discovered on Costa Rica's deep-sea seamounts
Scientists exploring seamounts off the coast of Costa Rica have discovered a new coral so genetically and morphologically distinct that it required the creation of an entirely new family for its classification.
Exoma analisa apenas de 1% a 2% do DNA; genoma completo pode revelar alterações que o prim
O exoma não pode continuar sendo tratado como o teto da investigação genética, mas sim como um degrau inicial. Reanalisar dados antigos e migrar para o sequenciamento do genoma completo são atitudes que devolvem às famílias a esperança e o direito a uma resposta. Twist Bioscience
Brain immune cell map explains how defenses shift during Alzheimer's progression
The brain's immune cells are increasingly recognized as key players in Alzheimer's disease, but exactly how they change as the disease develops has remained unclear. A new study published in Nature Genetics provides the most comprehensive map to date of these cells, identifying a
AI Is Helping Solve the Intricate Genetic Puzzle of Schizophrenia
Recent findings provide one of the most detailed pictures to date of the genetic architecture of schizophrenia, opening up new avenues for research into the disorder.
DNA repair enzymes favor specific sequences, shaping mutation patterns in the human genome
When a wound does not heal properly, it leaves a scar. Similarly, mutations—which are permanent changes to genetic code—are often the result of damaged DNA that has not been properly repaired. Mutations can impede the function of genes and lead to disease and aging, but they are
