How did the Butterfly Nebula get its wings? It"s complicated
Planetary nebulae form when red giant stars expel their outermost layers as they run out of helium fuel—becoming hot, dense white dwarf stars that are roughly the size of Earth. The material that was shed, enriched in carbon, forms dazzling pattern.....»»
Simple software creates complex wooden joints
Wood is considered an attractive construction material for both aesthetic and environmental purposes. Construction of useful wood objects requires complicated structures and ways to connect components together. Researchers created a novel 3D design a.....»»
A mathematical framework enables accurate characterization of shapes
In nature, many things have evolved that differ in size, color and, above all, in shape. While the color or size of an object can be easily described, the description of a shape is more complicated. In a study now published in Nature Communications,.....»»
Discovery of new praying mantis species from the time of the dinosaurs
A McGill-led research team has identified a new species of praying mantis thanks to imprints of its fossilized wings. It lived in Labrador, in the Canadian Subarctic around 100 million years ago, during the time of the dinosaurs, in the Late Cretaceo.....»»
Butterflies create jet propulsion with a clap of their wings
The whimsical, wafting flight of butterflies may not give the impression of top aerodynamic performance, but research published on Wednesday suggests their large flexible wings could be perfectly designed to give them a burst of jet propulsion......»»
Monarch butterfly population moves closer to extinction
The number of western monarch butterflies wintering along the California coast has plummeted precipitously to a record low, putting the orange-and-black insects closer to extinction, researchers announced Tuesday......»»

Finding the right firewall for your small business might seem like a complicated task. There are a number of great solutions out there......»»
New fossil provides clarity to the history of Alligatoridae
Families are complicated. For members of the Alligatoridae family, which includes living caimans and alligators—this is especially true. They are closely related, but because of their similarity, their identification can even stump paleontologists......»»
Asian butterfly populations show different mimicry patterns thanks to genetic "switch"
A new study by researchers at the University of Chicago and the City College of New York (CCNY) has identified a unique, genetic "mimicry switch" that determines whether or not male and female Elymnias hypermnestra palmflies mimic the same or differe.....»»
Intel discontinues 300-series chipset motherboards
Intel isn’t slow to pull the curtain down on its products when replacements are waiting in the wings. Last month, the company discontinued its entire 9th-gen Coffee Lake Refresh line, including the still-excellent Core i9-9900K. Its predecessor, th.....»»
Study of nebula IRAS 00500+6713 suggests its central star is unlike any seen before
A team of researchers from Potsdam University and Kazan Federal University has found evidence of a previously unknown kind of star in nebula IRAS 00500+6713. In their paper published in the journal Astronomy & Astrophysics, the group describes their.....»»
How an embryo tells time
It is estimated that the majority of pregnancies that fail do so within the first seven days after fertilization, before the embryo implants into the uterus. In this time period, a complicated cascade of events occurs with precise timing. One particu.....»»
Identifying Canada"s key conservation hot spots highlights problem
To stop biodiversity loss, Canada recently committed to protecting 30% of its land and sea by 2030. But making conservation decisions about where to locate new protected areas is complicated. It depends on data both about biodiversity and about a ran.....»»
How roundworms decide the time is right to grow
Transforming a fertilized egg into a fully functional adult is a complicated task. Cells must divide, move, and mature at specific times. Developmental genes control that process, turning on and off in a choreographed way. However, the environment in.....»»
Cooperation is key to addressing climate change
Climate change is our most complicated global pollution challenge, and cooperation is the key to solving it, according to a new book from a Binghamton University economist......»»
Feds to delay seeking legal protection for monarch butterfly
Federal officials on Tuesday declared the monarch butterfly "a candidate" for threatened or endangered status, but said no action would be taken for several years because of the many other species waiting for that designation......»»
Full-Wave EM Simulations: Electrically Large Antenna Placement and RCS Scenarios
Our software, based on Method-of-Moments, can analyze various complex scenarios including complicated and electrically large models using desktop workstations Handling various complex simulation scenarios with a single simulation method.....»»
Creating a ground plan for stonefly evolution
If a creature with eight legs, a large abdomen, and lots of eyes comes crawling your way, even if you have never seen one like it before, you know instinctively that it is a spider. Likewise, an animal with wings, feathers, and a beak is unlikely to.....»»
Data privacy startup eXate raises £2.3M Seed led by Outward VC
Accessing and sharing data is a complicated issue for large businesses, and doing this in a secure, compliant way is a problem for many. eXate, a London-based data software firm is attacking this problem and has now raised a £2.3 million seed round.....»»
