Why are some animals committed to their mates and others are not? According to a new study led by researchers at The University of Texas at Austin that looked at 10 species of vertebrates, evolution used a kind of universal formula for turning non-monogamous species into monogamous species -- turning up the activity of some…

A new way to genetically tweak photosynthesis boosts plant growth
A genetic hack to make photosynthesis more efficient could be a boon for agricultural production, at least for some plants. This feat of genetic engineering simplifies a complex, energy-expensive operation that many plants must perform during photosynthesis known as photorespiration. In field tests, genetically modifying tobacco in this way increased plant growth by over 40 percent. If…

Tracking Development Cell by Cell is Science’s Breakthrough of 2018
Science has chosen single-cell analyses of gene activity through time as its 2018 Breakthrough of the Year, honoring a trifecta of methods that together are enabling researchers to determine, at the individual cell level, which genes are turned on and off as an early embryo develops. "In 2018 alone, studies detailed how a flatworm, a fish, a…

The Miami blue was fluttering toward extinction. Then the scientists showed up
One crisp, sunny afternoon this month, grad student Sarah Steele Cabrera headed down a sandy path at Long Key State Park carrying two nylon bug containers. Cabrera had scouted out the park, a former fishing camp fashioned into an early version of glamping by railroad tycoon Henry Flagler and now a tangle of gumbo limbo,…

Butterfly sanctuary expected to be plowed over for Trump’s border wall
A protected habitat of butterflies along the Rio Grande is expected to be plowed over to clear the way for President Trump's border wallafter the U.S. Supreme Court rebuffed a challenge by environmental groups. The justices this week upheld a District Court ruling to allow the Trump administration to bypass 28 federal laws, including the Endangered…

What sets primates apart from other mammals?
University of Otago researchers have discovered information about a gene that sets primates -- great apes and humans -- apart from other mammals, through the study of a rare developmental brain disorder. Dr Adam O'Neill carried out the research as part of his PhD at the University of Otago, under the supervision of Professor Stephen…

Early Thanksgiving Counts Show a Critically Low Monarch Population in California
The California overwintering population has been reduced to less than 0.5% of its historical size, and has declined by 86% compared to 2017. Each year, during a three-week period around Thanksgiving, scores of volunteers fan out through coastal California to find and count overwintering monarch butterflies as part of the Western Monarch Thanksgiving Count. The results…

Oxygen could have been available to life as early as 3.5 billion years ago
Microbes could have performed oxygen-producing photosynthesis at least one billion years earlier in the history of the Earth than previously thought. The finding could change ideas of how and when complex life evolved on Earth, and how likely it is that it could evolve on other planets. Oxygen in the Earth's atmosphere is necessary for…

First risk genes for ADHD found
A major international collaboration headed by researchers from the Danish iPSYCH project, the Broad Institute of Harvard and MIT, Massachusetts General Hospital, SUNY Upstate Medical University, and the Psychiatric Genomics Consortium has for the first time identified genetic variants which increase the risk of ADHD. The new findings provide a completely new insight into the…

Embryological study of the skull reveals dinosaur-bird connection
Birds are the surviving descendants of predatory dinosaurs. However, since the likes of Tyrannosaurus and Velociraptor, some parts of their anatomy have become radically transformed. The skull, for instance, is now toothless, and accommodates much larger eyes and brain. Skulls are like 3-D puzzles made of smaller bones: As the eye socket and brain case…
