Super-black feathers on these guys are like looking into a dark cave.
Male Birds of Paradise have patches of super-black plumage that absorb 99.95 percent of light. New research identified their feathers' microscopic structures that make them look so very dark.
A conversation between a biologist and a philosopher on the relationship between man and divinity.
Rey (Daisy Ridley), in
Star Wars: The Last Jedi, ponders the light and dark sides of the Force.
Star Wars: The Last Jedi leaves many questions about the saga in a galaxy far, far away unanswered. Fortunately, biology may offer a insights on the Force, midi-chlorians, clones, and Rey's lineage.
Delivering genetic material is a key challenge in gene therapy.

One big challenge for gene therapies is delivering DNA or RNA safely to cells inside patients' bodies. New nanoparticles could be an improvement over the current standard – repurposed viruses.
Modern advances come with new liabilities.
Biologists' growing reliance on computers advances the field – but comes with new risks. The first step toward improved cyberbiosecurity is increasing awareness of possible threats.
Though not this obvious from the outside, plants are keeping time.
Precisely calibrated timekeepers are found in organisms from all domains of life. Biologists are studying how they influence plant/pathogen interactions – what they learn could lead to human medicines.
Lynn Margulis receiving the National Science Award from U.S. President Bill Clinton in 1999.
Lynn Margulis (1938-2011) was a courageous scholar whose remarkable work on the role of symbiosis in evolution stands as a magisterial contribution of science.
Is this how we got the sperm and the egg?
An ancient sexual conflict over mitochondrial inheritance may be responsible for the evolution of the two sexes as we know them.
Worms do have something in their mouth that they can poke out, like a tongue. It is called a stylet.
The short answer is no. But worms can use different parts of their body to do some of the jobs that our tongues do - like tasting and crushing food.
What can mating yeast tell us about new drugs?
By exploiting the way yeast cells mate, researchers have figured out a quicker, easier way to identify on- and off-target drug interactions.
Allergies may be in the genes that are passed down from parents to children.

Younus, age 9, wants to know how people become allergic to food.
Could millennia of gendered environments prevent the development of genetic mechanisms for gender differences?
A stable environment that teaches men to be men and women to be women could be helping to enforce gender across generations.
His anti-PC 'manifesto' might be filled with nonsense, but that doesn't mean James Damore's thoughts have no value, or that he should have been fired.
Color-changing cells in an Atlantic squid’s skin contain light-sensitive pigments.
We're used to thinking of our eyes detecting light as the foundation of our visual system. But what's going on in other cells throughout the body that can detect light, too?
Simple and inexpensive gene-editing technology such as CRISPR has made the creation of genetically modified organisms much easier. But could nature still keep the upper hand?
Is the evolution of human-like intelligence inevitable, or exceptional?
How can life on Earth help us understand life in space? To answer this question, we compare biological clocks and geological rocks and find that they tick uniformly.
How do they each know what to do?
Researchers identified simple behavioral rules that allow these tiny creatures to collaboratively build elaborate structures, with no one in charge.

Today algorithms are ubiquitous, yet often misunderstood. Rather than mysterious entities, they're closer to recipes, and the quality of the output depends on the input – in their case, data.
Once the coat around the seed is moistened, the embryo cells expand and burst out in a process called germination.
A seed contains nearly everything a tree needs to get growing. Just add a dash of water, a bit of warmth and the right location, and you'll be seeing green in no time.
Laboratory mice are among the first animals to have their diseases treated by CRISPR.

A new research paper reports dangerous side effects in CRISPR-edited mice. Some scientists are pushing back, placing blame for the unwanted mutations on the experiment, not the technique.
