Researchers use unconventional method to help solve issue plaguing crops around the world: ‘Our research [has] remarkable potential’

New genetic research from the University of Florida may help make key crops such as potatoes, tomatoes, and peppers more resistant to disease and environmentally resilient as well as increase their nutritional value.

“Our research illustrates the remarkable potential of combining deep taxonomic expertise with cutting-edge biotechnology,” author Fabio Pasin told the Chinese Academy of Sciences, via Phys.org. “By focusing on the Solanaceae family, we can enhance not only widely recognized crops but also bring underutilized species into the agricultural mainstream, improving food security and enriching nutritional diversity across the globe.”

Researchers used recombinant virus technologies to give new breeds of plants particular traits. This method is very specific about promoting certain traits in new breeds. Scary as it might sound to use an engineered virus to change the DNA of our food, it’s a way of improving biodiversity in agriculture when farming has become more and more homogeneous and thus vulnerable.

New Research Exposes a Shocking Global Failure in Heart Disease Treatment

A major international study reveals that most people with cardiovascular disease.

Cardiovascular disease (CVD) encompasses a range of disorders affecting the heart and blood vessels, including coronary artery disease, heart attack, stroke, and hypertension. These conditions are primarily driven by atherosclerosis, a process where plaque builds up in the arterial walls, leading to narrowed or blocked arteries. Risk factors include smoking, unhealthy diet, lack of exercise, obesity, and genetic predisposition. CVD remains a leading cause of global mortality, emphasizing the importance of lifestyle changes, medical interventions, and preventive measures in managing and reducing the risk of heart-related illnesses.

ADHD can be diagnosed by looking at brainwaves. Here’s the neuroscience behind it

Children with attention deficit hyperactivity disorder (ADHD) do not have a behavioral disorder, nor are they lazy, or lacking in manners and boundaries. Their brains mature in a different way, with different patterns of neurological activity and a number of neurochemical differences. For this reason, ADHD is considered to be a neurodevelopmental disorder.

These neurological imbalances manifest as attention difficulties, disorganization, or hyperactivity and impulsivity. While these are most noticeable in childhood, where prevalence is estimated at 5%, ADHD can persist into adulthood, where prevalence is 2.5% of the population. ADHD can therefore have social, academic and occupational impacts throughout a person’s life.

Although there are risk factors (such as mothers smoking during pregnancy or ), these have not been shown to directly cause ADHD. Genetic factors play a more significant role, as 74% of cases are hereditary.

Nature-inspired nanotechnology acts as body’s own courier service for genetic medicines

A large research team led by nanotechnologist Roy van der Meel rebuilt the body’s own proteins and fats into nano-delivery vans that get genetic medicines to exactly the right place in the body. In a joint effort with researchers from Radboudumc, they worked for five years on this nanotransport system, the results of which were published in Nature Nanotechnology.

With his rugged beard and signature lumberjack shirt, nanotechnologist Roy van der Meel seems to have walked straight out of a Canadian forest hut instead of a high-tech lab. In Canada, Van der Meel did indeed work as a postdoc for Professor Pieter Cullis, founder of the nanotechnology used for messenger RNA vaccines. Five years ago, he exchanged Vancouver for a spot in Eindhoven. Professor Willem Mulder brought Van der Meel to TU/e because of his RNA nanotechnology expertise.

Diseases that are currently difficult to cure, such as certain cancers and , can benefit from genetic drugs based on RNA. But then we must be able to get those medicines to the right place and that turns out to be a huge task.

CIA Report Reignites COVID-19 Origins Debate

As long as you have problems posting, I would recommend using a “throwaway” account to do your posting so you never lose your main account. A few months ago, I actually got 2 of my “throwaway” accounts UNBANNED. It is cool when you end up gaining accounts instead of losing them.

S timeline but they almost never complain recently.

The weekend release of the US Central Intelligence Agency (CIA) report favouring a laboratory leak as the likely origin of COVID-19 – albeit with “low confidence” – has reignited a vitriolic debate.

On the one side of the divide are those who argue that SARS-CoV2, the virus causing COVID-19, originated from a lab leak from the Wuhan Institute of Virology (WIV) that was studying coronaviruses in bats.

Some researchers who favour the lab-leak thesis argue that the virus contains unusual features that indicate it may have been genetically modified by humans. These focus on the virus’s furin cleavage site, a strange feature on the spike protein of the virus that is not present in other coronaviruses, that cast doubt on whether the virus had evolved naturally.

BIOTECHNOLOGY in the Future: 2050 (Artificial Biology)

Biopunk androids replicants.

What happens when humans begin combining biology with technology, harnessing the power to recode life itself.

What does the future of biotechnology and genetic engineering look like? How will humans program biology to create organ farm technology and bio-robots. And what happens when companies begin investing in advanced bio-printing, artificial wombs, and cybernetic prosthetic limbs.

Other topic include: bioengineered food and farming, bio-printing in space, new age living bioarchitecture (eco concrete inspired by coral reefs), bioengineered bioluminescence, cyberpunks and biopunks who experiment underground — creating new age food and pets, the future of bionics, corporations owning bionic limbs, the multi-trillion dollar industry of bio-robots, and bioengineered humans with super powers (Neo-Humans).

As well as the future of biomedical engineering, biochemistry, and biodiversity.

Scientists May Have Found Traces of an Extinct Genetic Code That Came Before DNA

“ tabindex=”0” amino acids and incorporated sulfur-based compounds much earlier than previously thought. This challenges long-standing experiments and opens the door to the possibility that extinct genetic codes existed before ours.

Cracking the Code of Life’s Origins

Despite awe-inspiring diversity, nearly all life on Earth — from tiny bacteria to massive blue whales — shares the same genetic code. But exactly how and when this code emerged remains a topic of scientific debate.

Revolutionary Biology Discovery Combines DNA and RNA To Fight Cancer

A study reveals DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
