Can’t boot from a DVD/CD drive

In order to install a new operating system on a computer, you can make a bootable DVD that includes the software to install the new system, put it in the DVD/CD reader, and reboot your computer. If all goes well your computer will boot off the DVD/CD reader and then you follow the install process…

Here are some more unsung heroes of research: scanners (the human kind). In the 1950s, Donald Glaser invented the bubble chamber – a way to track infinitesimally small quantum particles as they winked in and out of existence. The idea – which may or may not have been tested in beer – was to create…

Researchers in Peru have discovered four new species of tiny so-called “glass frogs” (family: Centrolenidae). Centrolene charapita: with the yellow splotches on its back, this species was aptly named after little yellow chili peppers. Their hindlegs also had fleshy little zigzag-like protuberances whose purpose is unknown. Cochranella guayasamini: This species is mostly green with yellow encircling its…

Paleogeneticist Dr. Johannes Krause (University of Tübingen, Germany) and colleagues were interested in the origin of tuberculosis (TB) in the Americas. Since strains of TB found in the Americas are related to strains found in Europe, prior theories held that Spaniards may have introduced it to the Americas while colonizing South America.  The problem with…

They are also resistant to the development of cancer as mentioned in this prior post. According to the CDC, cardiovascular…

City life makes bigger spiders

A new study from researchers at the University of Sydney shows that golden orb-weaving spiders (Nephila plumipes) that live in the city are larger and produce more offspring as compared to country living. When they say the spiders are big, they mean really big. The females can reach up to 20-25mm (males are only ~5mm).…

Scaredy snakes?

Dr. Greg Byrnes (Siena College, Loudonville, NY) and Dr. Bruce Jayne (University of Cincinnati, OH) discovered that snakes use more force than is necessary to support their weight when climbing.  To climb, snakes rely on friction and repeatedly contract and extend their bodies, a process called concertina locomotion. To study the forces generated by snakes…

Do the math: There are actually two answers to this question. First, “maths” looks plural and is preferred by some because “mathematics” is plural. The problem with that is “mathematics” is no more plural than “physics” or any other compound noun. It is a rational sounding utterly incorrect argument. If we said “mathematics are cool”…
