All 5 DNA And RNA Building Blocks Found In Asteroid Ryugu Samples. Here's What It Means
The study's lead author said that the presence of nucleobases "does not mean that life existed on Ryugu".

New Experiments Suggest RNA Could Have Formed Naturally, Supporting ‘RNA World’ Origin of Life Theory
Experiments show RNA, a crucial molecule for life, could form naturally on early Earth with borates stabilising ribose and aiding phosphate production. Protoplanet impacts may have delivered RNA ingredients, supporting the RNA world hypothesis and suggesting life’s building blocks could emerge efficiently on Earth and potentially Mars.

Scientists Discover 40,000-Year-Old RNA In Frozen Woolly Mammoth
To search for even older RNA, Pour and his team focused on the permafrost regions of Siberia, where thawing soil has yielded many amazing discoveries.

NASA New Study Challenges RNA's Role in Life’s Molecular Handedness Mystery
NASA-backed research published in Nature Communications has found that RNA molecules exhibit no chemical preference for left- or right-handed amino acids under simulated early-Earth conditions. This discovery, led by UCLA researchers, challenges the idea that RNA played a decisive role in determining the molecular handedness seen in modern life, kn...

"Exciting Idea": In A First, Scientists Recover Ribonucleic Acid From Extinct Animal
Scientists have for the first time recovered Ribonucleic acid (RNA) from an extinct species, the Tasmanian tiger, raising hope for the resurrection of animals once thought lost forever, Stockholm University researchers told AFP.

Researchers Identify RNA Precursors in Molecular Clouds Located in the Centre of the Milky Way
An international team of researchers have spotted traces of an organic class of molecules at the centre of the Milky Way which are precursor to molecules essential for life. It is believed that originally life was based on only RNA (ribonucleic acid) on Earth while DNA (deoxyribonucleic acid) and protein enzymes evolved later. RNA is capable of per...

New Study Reveals How Marine Viruses May Aid in Mitigation of Climate Change
A new study suggests how 5,500 marine RNA virus species may help push carbon absorbed from the atmosphere to permanent storage on the ocean floor. The effort aims to learn more about the organisms that live in the ocean and do the majority of the work of absorbing half of the human-generated carbon in the atmosphere and producing half of the oxygen...

What 'Silences' X Chromosome In Girls Decoded
Scientists led by an Indian-origin researcher may have discovered what actually silences the X chromosome in girls, a finding that could lead to ways to counteract X-linked diseases in women.

Blood-Based Biopsy to Improve Cancer Detection: Study
A new blood-based biopsy that requires analysing a sample equivalent to one drop of blood can make cancer detection a lot simpler, says a new study.

Starvation Genes Run in Families
If your ancestors have faced starvation at some point of time, chances are that you may also have inherited the "memory of starvation" and can pass this to future generations.

New treatment for HIV
Human HIV infection may soon be treated by the same natural defence strategy which is used by various species to ward off invaders. Certain pieces of genetic elements called short interfering RNA (siRNA) turn off those genes that are vital for the production of proteins which the virus uses to enter and infect cells. Certain viruses such as HIV in...
