How much are we learning about the genome? Natural selection is science's best critic
Even as they've struggled to highlight parts of the human genome worth investigating, scientists have wondered how much they're actually learning through the methods they use. Now, two researchers have determined that natural selection and our own evolutionary history might be science's best critics, and guides for future research.

Mysteries of the primrose unraveled
Plant scientists have succeeded in unraveling the complete genome sequence of the common primrose -- the plant whose reproductive biology captivated the Victorian naturalist Charles Darwin. The research team has identified, for the first time, the landscape of genes which operate within the primrose's two different flowering forms that are involved in the reproductive process. This adds fresh insight to a puzzle that scientists have been grappling with for over 150 years.

New genetic testing technology enhances precision of analysis of clinical biomarkers
Scientists have announced the invention of a genetic testing technology that allows the number of clinical biomarkers to be analyzed at the single-molecule level, which enhances the sensitivity of tests in precision medicine and will make them more affordable in future. The TAC-seq method, for which a patent is pending, is already being used in fertility clinics to determine the personal variations in the menstrual cycle for opportune embryo transfer.

Children of problem drinkers more likely to marry someone with a drinking problem
Children of parents who have alcohol use disorder are more likely to get married under the age of 25, less likely to get married later in life, and more likely to marry a person who has alcohol use disorder themselves, according to a new study.

CBD in marijuana may worsen glaucoma, raise eye pressure
A study has found that CBD -- a major chemical component in marijuana -- appears to increase pressure inside the eye of mice, suggesting the use of the substance in the treatment of glaucoma may actually worsen the condition.

The full story on climate change requires the long view
Researchers offer a new calculation that provides the long view of what nine different world regions have contributed to climate change since 1900. They also show how that breakdown will likely look by 2100 under various emission scenarios.

Scientists design new material to harness power of light
Scientists have long known that synthetic materials -- called metamaterials -- can manipulate electromagnetic waves such as visible light to make them behave in ways that cannot be found in nature. That has led to breakthroughs such as super-high resolution imaging. Now, scientists are taking the technology of manipulating light in a new direction.

How a personality trait puts you at risk for cybercrime
Impulse online shopping, downloading music and compulsive email use are all signs of a certain personality trait that make you a target for malware attacks. New research examines the behaviors -- both obvious and subtle -- that lead someone to fall victim to cybercrime involving Trojans, viruses, and malware.
