We assume that all biological processes come to an end when we die, but new research shows that many genes remain active for up to four days following clinical death. These zombie genes can’t bring a person back to life, but this discovery has serious implications for forensics and organ donor recipients.
Six months after researchers in China bioengineered monkeys to have autism, a Japanese team of scientists has used the same technology to create monkeys with Parkinson’s. It’s a scientific first, and it could lead to effective treatments—but do the ends justify the means?
Using the CRISPR gene-editing tool, scientists from Harvard University have developed a technique that permanently records data into living cells. Incredibly, the information imprinted onto these microorganisms can be passed down to the next generation.
In an effort to tackle the organ donor shortage, researchers in the United States have successfully created part-human, part-pig embryos and implanted them into a sow. Eventually, these animals could act as incubators for human organs, which concerns some ethicists.
Last month, a group of scientists, lawyers, and entrepreneurs gathered in secret to discuss the possibility of creating a synthetic human genome from scratch. Details of the plan have finally been made public, and it’s as ambitious as it sounds. But critics say they founders of the new project are avoiding the tough…
The precise origin of our canine companions is mired in controversy. But a new study suggests that dogs emerged from not one but two different populations of ancient wolves. What’s more, this dual domestication happened on opposite sides of the Eurasian continent.
Canadian scientists have uncovered a single genetic mutation that significantly heightens a person’s chance of developing a progressive and severe form of multiple sclerosis. While no single factor is responsible for causing the neurological disease, the discovery points to possible treatment options.
Scientists say a groundbreaking fertility treatment to correct potentially harmful genetic mutations has the potential to backfire, recreating the exact mutation the intervention was meant to fix. It’s a problem that could put an immediate halt to the pending practice—but a work-around may be possible.
For the first time ever, scientists have sequenced the genome of the world’s tallest land species, the giraffe. Surprisingly, this majestic creature required only a small handful of mutations to attain its remarkable physical stature and physiology—but these mutations packed an evolutionary punch.
Planet Earth is doomed with a fast growing global population and a limited amount of farmland to produce food for everyone. That means that we’re going to need to figure out how to maximize what we’ve got—and researchers just made a major breakthrough in getting the most from our crops.
Last year, a biotech startup called Clear Labs performed DNA testing on a bunch of hot dogs and discovered that they often contain more than the label advertises. The same company has now used its arsenal of molecular technologies to break down America’s other favorite meat-on-a-bun product: burgers. Once again, there…
In a lush conservation park in central Kenya, the world’s last three northern white rhinos are unable to breed. When they die, the subspecies will go extinct. That is unless a complex, controversial plan involving tissue cryobanks and test tube embryos can actually work.
Remember when we told you that the Venus flytrap can actually count? That’s how this carnivorous plant knows the difference between the presence of prey in its trap and a false alarm. Now the same team of German scientists is back with insight into how the Venus flytrap turned the evolutionary tables to become…
As a breed, labrador retrievers often have serious food-related issues—a behavioral quirk that often leads to over-eating and canine obesity. Researchers have finally figured out why, and the answer could influence the way we treat human obesity.
Leveraging the pre-existing power of CRISPR, a team of researchers has made an important adjustment to the groundbreaking gene-editing tool that could make it precise enough for human applications.
Over a century ago, scientists discarded a proposed theory that human limbs evolved from gills, given the lack of evidence in the fossil record. That theory is being revisited in light of new genetic results just published in the journal Development.
When Saturday Night Live aired a skit this weekend riffing on America’s new heroin epidemic—a satirical fake ad for “Heroin A.M.” to help addicts remain productive while using—many people weren’t laughing. That’s because heroin and other powerful opiates are killing more people than ever, across all demographics. So…
Just one year after scientists in China made history by modifying the DNA of human embryos, a second team of Chinese researchers has done it again. Using CRISPR/Cas9, the researchers introduced HIV-resistance into the embryos, showcasing the tremendous potential for gene-editing.
Scientists are excited about the prospect of using CRISPR, a powerful gene-editing tool, to combat HIV. A discouraging follow-up study shows that HIV is capable of developing a resistance to the genetic attack—but scientists say CRISPR’s battle with HIV is far from over.
Researchers from Temple University have used the CRISPR/Cas9 gene editing tool to clear out the entire HIV-1 genome from a patient’s infected immune cells. It’s a remarkable achievement that could have profound implications for the treatment of AIDS and other retroviruses.
