Changes In Body Fat Due To Obesity Can Contribute To Alzheimer's Disease: Study
In the brain, the PE particles disrupt communication between neurons, weaken immune system and promote buildup of amyloid proteins, which are naturally present but condense into clumps in Alzheimer's disease.

How Plants Fight Viruses: New Study From Hyderabad Researchers
Hyderabad, May 13 (IANS) Researchers at the CSIR-Centre for Cellular and Molecular Biology (CCMB) have revealed a key defence system in plants to fight viruses.

Are Hantavirus Tests Like Covid Tests? Doctors Explain Key Differences
Unlike Covid-19, hantavirus cannot be detected using rapid antigen kits. Doctors explain why diagnosis depends on specialised blood tests, PCR analysis and clinical suspicion, especially during severe respiratory illness outbreaks.

Blood Test Could Reveal How Disease Progresses, Response To Treatment: Study
A blood test might help predict how one's illness trajectory will proceed and how well they might respond to treatment, according to a study.

New DNA-Based Therapy Can Help Lower 'Bad Cholesterol' Without Statins, Finds Study
Researchers used tiny DNA-based molecules to cut levels of LDL (bad) cholesterol by nearly 50% in animal models. This was done without the side effects that are often linked to statins.

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.

COVID-19 May Change Offspring's Brain Development, Study In Mice Finds
Changes in sperm caused by COVID-19 in a mouse could affect the offspring's brain development and cause anxious behaviours, a study has found.

US Health Department Pulls Back $500 Million In Funding mRNA Vaccines
The US Department of Health and Human Services is ending contracts to develop vaccines using messenger RNA technology, another step in the agency's changing practices toward vaccines under Secretary Robert F Kennedy Jr.

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...

How Rainwater Helped Stabilise Early Cells, Enabling Life's Complexity on Earth
Recent research led by Aman Agrawal, in collaboration with experts from the University of Chicago and University of Houston, uncovers the potential role rainwater played in stabilising protocells on early Earth. Their findings show how this helped prevent RNA leakage and uncontrolled mixing, allowing the formation of stable genetic material. This n...

New AI Model To Boost Patient Response To Cancer Therapy
The new tool DeepPT, developed by researchers at Australian National University (ANU), predicts a patient's messenger RNA (mRNA) profile. This mRNA -- essential for protein production -- is also the key molecular information for personalised cancer
