Unity dev group dissolves after 13 years over “completely eroded” company trust
Meanwhile, major game devs say fee structure changes haven't won them back. Enlarge / A partnership of 13 years has ended over a complete lack of trust in the company behind the Unity engine. (credit: Boston Unity Group).....»»
Scientists marry MRI, ultrasound, and optoacoustics for improved medical exams
Physicians and researchers rely on biomedical imaging to examine the structure and function of living tissue. This enables disease diagnostics and experiments that reveal the mechanisms behind pathologies and ways to treat them. The most popular tech.....»»
Chromosomal instability in cancer cells causes DNA damage and promotes invasiveness: Study
Chromosomal instability is a phenomenon characterized by rapid changes in the number and structure of chromosomes during cell division. It is very common in solid tumors and it is linked to the aggressive spread of cancer, that is to say, metastasis......»»
The impact of solar eclipses on the structure and dynamics of Earth"s upper atmosphere
Solar eclipses can have a noticeable impact on the structure and dynamics of Earth's upper atmosphere—the ionosphere. This is primarily due to the sudden reduction in solar radiation reaching the Earth's atmosphere during the eclipse. Since the ion.....»»
Unifor ratifies Ford deal with 54% approval; pact includes wage increase, new pension structure
Membership approval of the three-year deal, which was unanimously endorsed by Unifor’s auto bargaining committee, locks in substantial wage gains and pension improvements for workers, and will see Ford invest to expand production at one of its Wind.....»»
Caribbean parrots thought to be endemic are actually relicts of millennial-scale extinction
In a new study published in PNAS, researchers have extracted the first ancient DNA from Caribbean parrots, which they compared with genetic sequences from modern birds. Working with fossils and archaeological specimens, they showed that two species t.....»»
This simple log structure may be the oldest example of early humans building with wood
Researchers have uncovered a simple structure from the Stone Age that may be the oldest evidence yet of early humans building with wood......»»
The deep genetic structure of Africa reveals unique ancestry of inhabitants of the Angolan Namib
Africa is the birthplace of modern humans and the continent with the highest level of genetic diversity. While ancient DNA studies are revealing some aspects of the genetic structure of Africa before the spread of food production, issues concerning D.....»»
How does voltage drive nonmetallic catalysts to perform electrocatalytic reactions?
Understanding how voltage drives nanoscale electrocatalysts to initiate reactions is a fundamental scientific question. This is especially challenging when dealing with non-metallic electrocatalysts due to their low inherent carrier concentration, wh.....»»
Why flat-faced dogs seem more cuddly than longer-muzzled dogs
A team of ethologists, natural scientists and psychologists affiliated with several institutions in Hungary has found evidence suggesting that some of the attraction by humans to flat-faced dogs can be tied to their stronger reliance on being helped.....»»
Migratory birds can be taught to adjust to climate change, study shows
One result of climate change is that spring is arriving earlier. However, migratory birds are not keeping up with these developments and arrive too late for the peak in food availability when it is time for breeding. By getting the birds to fly a lit.....»»
Astronomers find abundance of Milky Way–like galaxies in early universe, rewriting cosmic evolution theories
Galaxies from the early universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the universe, according to new research published today......»»
EU game devs ask regulators to look at Unity’s “anti-competitive” bundling
Company's power is a "market failure" with "significant vendor lock risk" for devs. Enlarge In the wake of Unity's sudden fee structure change announcement last week, a European trade group representing thousands of gam.....»»
How racism shapes Black motherhood in the US
Being a mom is hard. Being a Black mom is especially hard. A new study from North Carolina State University underscores the ways that being a Black mother in the United States involves navigating aspects of parenthood that are explicitly tied to deal.....»»
Study paves the way for new class of nanoscale devices, new opportunities in photonics
Non-Hermitian systems have numerous alluring optical properties at exceptional points (EPs) and have attracted extensive attention because of their great prospects in applications such as optical sensing, integrated optics, and other fields......»»
In helium-three, superfluid particles pair "like a dance in space"
Picture a nanoscale dance floor full of independently moving particles. When things really start to heat up—or, in this case, cool down—particles partner off, but on opposite sides of the space, "dancing" in synch as if telepathically......»»
Dinosaur feathers reveal traces of ancient proteins
Paleontologists at University College Cork (UCC) in Ireland have discovered X-ray evidence of proteins in fossil feathers that sheds new light on feather evolution......»»
Researchers" analysis of perching birds points to new answers in evolutionary diversification
When Charles Darwin traveled to the Galapagos Islands almost 200 years ago as a gentleman naturalist, he used the power of observation to develop his theory that species evolve over time......»»
Technique for 3D printing metals at the nanoscale reveals surprise benefit
