CRISPR, the disruptor — Heidi Ledford | Nature

“Researchers are considering how CRISPR could or should be deployed on organisms in the wild. Much of the attention has focused on a method called gene drive, which can quickly sweep an edited gene through a population. The work is at an early stage, but such a technique could be used to wipe out disease-carrying mosquitoes or ticks, eliminate invasive plants or eradicate herbicide resistance in pigweed, which plagues some US farmers.” Read more

Howard Hughes Medical Institute Selects 2015 Investigators

“The Howard Hughes Medical Institute (HHMI) announced today that 26 of the nation’s top biomedical researchers will become HHMI investigators and will receive the flexible support necessary to move their research in creative new directions. The initiative represents an investment in basic biomedical research of $153 million over the next five years.”

Chinese scientists genetically modify human embryos

David Cyranosk & Sara Reardon  - Nature.com

In a world first, Chinese scientists have reported editing the genomes of human embryos. The results are published1 in the online journal Protein & Cell and confirm widespread rumours that such experiments had been conducted — rumours that sparked a high-profile debate last month2, 3 about the ethical implications of such work.

DNA Editing of Human Embryos Alarms Scientists

By David Cyranoski — Scientific American

Amid rumors that precision gene-editing techniques have been used to modify the DNA of human embryos, researchers have called for a moratorium on the use of the technology in reproductive cells.

In a Comment published on March 12 in Nature, Edward Lanphier, chairman of the Alliance for Regenerative Medicine in Washington DC, and four co-authors call on scientists to agree not to modify human embryos — even for research.

“Such research could be exploited for non-therapeutic modifications. We are concerned that a public outcry about such an ethical breach could hinder a promising area of therapeutic development,” write Lanphier and his colleagues, who include Fyodor Urnov, a pioneer in gene-editing techniques and scientist at Sangamo BioSciences in Richmond, California. Many groups, including Urnov’s company, are already using gene-editing tools to develop therapies that correct genetic defects in people (such as by editing white blood cells). They fear that attempts to produce ‘designer babies’ by applying the methods to embryos will create a backlash against all use of the technology.Read more

Do gut bacteria control your mind?

Bacteria within you — which outnumber your own cells about 100 times — may be affecting both your cravings and moods to get you to eat what they want, and may be driving you toward obesity.

That’s the conclusion of an article published this week in the journal BioEssays by researchers from UC San Francisco, Arizona State University and University of New Mexico from a review of the recent scientific literature.

Astronauts Just Found Life In Outer Space — And Scientists Aren’t Sure How It Got There

By Zak Cheney-Rice — News.Mic

The news: Russian cosmonauts have discovered something remarkable clinging to the outside of the International Space Station: living organisms.

The microscopic creatures appeared during a space walk intended to clean the vessel’s surface, and were allegedly identified — incredibly — as a type of sea plankton. This is big: According to Sploid, Russian scientists are both “shocked by [the] discovery and can’t really explain how [it] is possible.”

“Results of the experiment are absolutely unique,” Russian ISS Orbital Mission Chief Vladimir Solovyev told the ITAR-TASS News Agency. “This should be studied further.”

Plant Engineered to Supercharge Photosynthesis with Hopes of Increasing Crop Yields

Written By: — Singularity Hub

While computers scientists find new ways to supercharge computers, a team of plant scientists have demonstrated that they can supercharge a plant.

Hoping to speed up plant photosynthesis, researchers from the US and UK have successfully upgraded a carbon-fixing enzyme vital to photosynthesis in a tobacco plant with two enzymes from cyanobacteria, which function at a faster rate. If photosynthesis can be performed more efficiently, plants would grow larger and crops could have higher yields, possibly as high as 60% according to computer models.

“This is the first time that a plant has been created through genetic engineering to fix all of its carbon by a cyanobacterial enzyme,” said Cornell Professor Maureen Hanson, a co-author of the study, in the release. She added, “It is an important first step in creating plants with more efficient photosynthesis.”
