“Is curing patients a sustainable business model?” Goldman Sachs analysts ask

Analyst Salveen Richter and colleagues laid it out:

The potential to deliver “one shot cures” is one of the most attractive aspects of gene therapy, genetically engineered cell therapy, and gene editing. However, such treatments offer a very different outlook with regard to recurring revenue versus chronic therapies… While this proposition carries tremendous value for patients and society, it could represent a challenge for genome medicine developers looking for sustained cash flow.

For a real-world example, they pointed to Gilead Sciences, which markets treatments for hepatitis C that have cure rates exceeding 90 percent. In 2015, the company’s hepatitis C treatment sales peaked at $12.5 billion. But as more people were cured and there were fewer infected individuals to spread the disease, sales began to languish. Goldman Sachs analysts estimate that the treatments will bring in less than $4 billion this year.

Harvard Scientists to Release Sun-Dimming Sky Chemical in 2019

Critics say that geoengineering efforts are Band-Aid solutions that treat the symptoms of climate change instead of the cause: global carbon emissions. Jim Thomas, the co-executive director of an environmental advocacy organization called the ETC Group, told Nature that he fears the Harvard project could push the concept of geoengineering into the mainstream.

But advocates say that anything that could buy some extra time in the face of looming climate catastrophe is worth exploring.

“I’m studying a chemical substance,” Harvard researcher Zhen Dai told Nature. “It’s not like it’s a nuclear bomb.”

With Personal Food Computers, nerd farmers are finding the best way to grow

In his book Tomatoland: How Modern Industrial Agriculture Destroyed Our Most Alluring Fruit, Barry Estabrook details how grocery store tomatoes are both less nutritious and delicious than those grown decades ago. Industrial farming now grows crops for yield, sacrificing taste and vitamins for an easy-to-harvest, shippable product. It’s why apples at your local supermarket are probably about a year old. Caleb Harper, a principal research scientist at MIT and director of the OpenAg Initiative, wants to use technology to grow food that’s healthier, tastier, and more sustainable.

“Growing for nutrition and growing for flavor, it’s not really something anyone does,” he told Digital Trends at the recent ReThink Food conference in Napa, California.

Tesla will live and die by the Gigafactory

Right now, in the desert just east of Reno, Nevada, Tesla is drilling into recently laid asphalt to install more electric vehicle chargers in the parking lot of the Gigafactory. The company has hired so many new workers in recent years that it needs more space to let them charge their Nissan Leafs, Chevy Bolts, Toyota Priuses, and, of course, Teslas. But before long, those chargers will be ripped right back out, along with the asphalt, and moved to a new spot to make room for more factory space.

Brilliant iron molecule could provide cheaper solar energy

For the first time, researchers have succeeded in creating an iron molecule that can function both as a photocatalyst to produce fuel and in solar cells to produce electricity. The results indicate that the iron molecule could replace the more expensive and rarer metals used today.

Some photocatalysts and are based on a technology that involves containing metals, known as . The task of the complexes in this context is to absorb solar rays and utilise their energy. The metals in these molecules pose a major problem, however, as they are rare and expensive metals, such as the noble metals ruthenium, osmium and iridium.

“Our results now show that by using advanced molecule design, it is possible to replace the rare metals with iron, which is common in the Earth’s crust and therefore cheap,” says Chemistry Professor Kenneth Wärnmark of Lund University in Sweden.

Study unlocks full potential of ‘supermaterial’ graphene

New research reveals why the “supermaterial” graphene has not transformed electronics as promised, and shows how to double its performance and finally harness its extraordinary potential.

Graphene is the strongest material ever tested. It’s also flexible, transparent and conducts heat and electricity 10 times better than copper.

After graphene research won the Nobel Prize for Physics in 2010 it was hailed as a transformative material for flexible electronics, more powerful computer chips and solar panels, water filters and bio-sensors. But performance has been mixed and industry adoption slow.

New catalyst material produces abundant cheap hydrogen

QUT chemistry researchers have discovered cheaper and more efficient materials for producing hydrogen for the storage of renewable energy that could replace current water-splitting catalysts.

Professor Anthony O’Mullane said the potential for the chemical storage of renewable energy in the form of hydrogen was being investigated around the world.

“The Australian Government is interested in developing a hydrogen export industry to export our abundant renewable energy,” said Professor O’Mullane from QUT’s Science and Engineering Faculty.

Next generation of biotech food heading for grocery stores

WASHINGTON (AP) — The next generation of biotech food is headed for the grocery aisles, and first up may be salad dressings or granola bars made with soybean oil genetically tweaked to be good for your heart.

By early next year, the first foods from plants or animals that had their DNA “edited” are expected to begin selling. It’s a different technology than today’s controversial “genetically modified” foods, more like faster breeding that promises to boost nutrition, spur crop growth, and make farm animals hardier and fruits and vegetables last longer.

The U.S. National Academy of Sciences has declared gene editing one of the breakthroughs needed to improve food production so the world can feed billions more people amid a changing climate. Yet governments are wrestling with how to regulate this powerful new tool. And after years of confusion and rancor, will shoppers accept gene-edited foods or view them as GMOs in disguise?
