In the late 1990s, scientists thought they were close to locating specific genes that controlled for human intelligence in all its manifestations: musical genius, analytical acumen, physical prowess, etc. But the truth turns out to be more complicated, says Harvard psychologist and linguist Steven Pinker. There are many genes — perhaps thousands — that affect human intelligence, and while manipulating them may have predictable benefits, the adverse consequences remain unpredictable. Thus experimenting with our so-called intelligence genes will likely be met with high levels of skepticism in caution. It’s proof, says Pinker, that technological advancement doesn’t always march to the drum beat of inexorable forward progress.

In a controversial move, a senior US scientific committee has given the green light to one of the most contentious forms of genome editing: where genetic changes made to human embryos will then be inherited by following generations.

For the first time, a panel of experts from two of the most recognised scientific institutions in the US has advised that this process – called germline editing – should be seriously considered as an option in the future, and not outright prohibited.

It’s a considerably more positive tone than the assessment of an international summit of scientists in December 2015, which declared that it would be “irresponsible to proceed” with germline editing unless safety issues and social consensus could be satisfied.

CRISPR/Cas9, a powerful gene editing technique that has already been used in a human, is thought by many as a “cut and paste” for DNA in living organisms. While in a sense that is what happens, delivering the ribonucleoprotein that does the genetic editing and the RNA that hones in on the target, into the cellular nucleus without being damaged is a challenge. That is why the efficiency of successful edits remains very low. Researchers at University of Massachusetts Amherst have now come up with nanoparticles that protect the protein and RNA as they’re brought to their work site.

The nanoparticles are engineered around their cargo and have shown a 90% success rate of getting the cargo into the nucleus, and a 30% editing efficiency, which is “remarkable” according to the researchers. So far the team has tested their technique on cultured cells, but they’re already working on trying the same in laboratory animals. As part of their research, they developed a novel way of tracking the Cas9 protein inside the cells, something that will certainly help other scientists in this area.

“By finely tuning the interactions between engineered Cas9En protein and nanoparticles, we were able to construct these delivery vectors. The vectors carrying the Cas9 protein and sgRNA come into contact with the cell membrane, fuse, and release the Cas9:sgRNA directly into the cell cytoplasm,” in a statement said Vincent Rotello, lead author of the study in ACS Nano. “Cas9 protein also has a nuclear guiding sequence that ushers the complex into the destination nucleus. The key is to tweak the Cas9 protein,” he adds. “We have delivered this Cas9 protein and sgRNA pair into the cell nucleus without getting it trapped on its way. We have watched the delivery process live in real time using sophisticated microscopy.”

CRISPR is now universally accessible. Learn how it will change everything from materials science to food science.

A new story out on Engadget, emphasizing the need to make government treat science and technology as a primary focus:

Zoltan Istvan didn’t have much of a chance at being president, but that didn’t stop him from campaigning as the Transhumanist Party’s candidate to promote his pro-technology and science positions. Now, he’s setting his sights a bit lower, and with a different party. Istvan announced this morning that he plans to run for governor of California in 2018 under the Libertarian Party.

“We need leadership that is willing to use radical science, technology, and innovation—what California is famous for—to benefit us all,” he wrote in a Newsweek article. “We need someone with the nerve to risk the tremendous possibilities to save the environment through bioengineering, to end cancer by seeking a vaccine or a gene-editing solution for it, to embrace startups that will take California from the world’s 7th largest economy to maybe even the largest economy—bigger than the rest of America altogether.”

In Brief

• Researchers were able to increase the weight of tobacco plants by around 14 to 20 percent compared to unmodified plants by adding in genes to improve the process of photosynthesis.
• If successful with other plants, the method could improve the yields of food crops such as cowpeas, rice, and cassava and decrease world hunger.

In terms of plants, the concept of genetically modified organisms (GMOs) often refers to the insertion of genetic information from one species of plant to another so that the recipient plant gains a desirable trait. This process has been used extensively to improve crop yields. For example, one type of rice has been made waterproof so that yields aren’t affected by heavy floods from typhoons.

Need to share this with a few folks researching glaucoma disease and treatment/ mutation reversal.

Elderly are frequently hospitalized due to their age-associated organ degeneration, the presence of co-morbidities, and their susceptibility to adverse insults. Alterations in functional status often occur during hospitalization, and the degree of functional decline can parallel the severity of illnesses. For older persons, gauging their pre-morbid and in-hospital functional status facilitates treatment planning and potentially functional restoration^1,2,3. While the identification of risk factors or markers of poor pre-morbid and in-hospital functional status may help facilitate this process, this area remains under-researched to date. Factors associated with functional decline in the hospitalized elderly include the types of morbidities and the reasons for their admission. Indeed, elderly with chronic kidney disease (CKD) are more likely to exhibit functional decline, beginning from the earlier stage of CKD to end-stage renal disease (ESRD)^4,5; functional dependency also predisposes individuals with CKD and ESRD to recurrent hospitalization and higher mortality.

Albuminuria and proteinuria, as the staging criteria for CKD in the most recent version of Kidney Disease Improving Global Outcomes (KDIGO) CKD guidelines, are both well-established predictors of subsequent renal function decline. There is increasing awareness that albuminuria and proteinuria have an independent role in the prediction of adverse outcomes apart from the baseline renal function. As explained above, although CKD is associated with poor functional status, it is still unclear whether proteinuria alone exhibits similar association with functional status regardless of CKD. No reports focus on this association using the severity of proteinuria among geriatric patients with acute medical illnesses.

To understand 1st how to solve things like cancer, or other immune deficiency disorders, or to solve the human system’s other mysteries; one must understand DNA v. RNA.

DNA is a deoxyribonucleic acid and is a hereditary material in all living organism. It is located in the nucleus of cell which is known as nuclear DNA. But small amount of DNA is also found in the mitochondria known as mtDNA or mitochondrial DNA whereas RNA is ribonucleic acid present in all living cells. It carries instructions from DNA which controls the synthesis of proteins but in some viruses RNA, instead of DNA carries the genetic information. Do you know who had reported first time nucleic acids in 1871 — Friedrich Miescher from nuclei of pus cells.

Yesterday, I shared the new cancer research discovery by Prof. Samie Jaffrey and his team. The following provides additional details on their discovery.

The human body is made of trillions of cells. Each fulfills a specific purpose, undergoes tremendous wear and tear and is eventually replaced. Despite extensive research, some questions related to protein production that fuels this simple process have gone unanswered. Fascinated by these intricacies, Prof. Samie Jaffrey, pharmacology, may have found part of the answer.

Jaffrey and his team discovered that messenger RNA molecules, responsible for conveying genetic information to protein producers in the cell, have special features that predetermine how much protein they generate. The discovery could provide scientists with a greater understanding of the causes of cancer and ways of regulating it.
