New rapid COVID-19 test the result of university-industry partnership
A partnership between UC Davis and Maurice J. Gallagher, Jr., chairman and CEO of Allegiant Travel Company, has led to a 20-minute COVID-19 test. The method pairs a mass spectrometer with a powerful machine-learning platform to detect SARS-CoV-2 in nasal swabs. A recent study published in Nature Scientific Reports shows the test to be 98.3% accurate for positive COVID-19 tests and 96% for negative

Studies connect hormone to breast cancer and uncover potential for novel targeted drugs
The hormone prolactin has long been understood to play a vital role in breast growth and development and the production of milk during pregnancy. But a pair of recent studies conducted at VCU Massey Cancer Center finds strong evidence that prolactin also acts as a major contributor to breast cancer development and that the hormone could inform the creation of targeted drugs to treat multiple forms

Skin and bones repaired by bioprinting during surgery
Fixing traumatic injuries to the skin and bones of the face and skull is difficult because of the many layers of different types of tissues involved, but now, researchers have repaired such defects in a rat model using bioprinting during surgery, and their work may lead to faster and better methods of healing skin and bones.

Pentagon Says SpaceX Near Collision Was a False Alarm
Four astronauts who traveled to the International Space Station on board the SpaceX Crew Dragon late last week experienced a bit of a scare: believing that a piece of space junk was zipping by too close to comfort , SpaceX HQ at Hawthorne instructed the astronauts to don their spacesuits in case of a collision. But now, according to an investigation by the US Space Command 18th Space Control Squa

Energy-saving gas turbines from the 3D printer
3D printing has opened up a completely new range of possibilities. One example is the production of novel turbine buckets. However, the 3D printing process often induces internal stress in the components which can in the worst case lead to cracks. Now a research team has succeeded in using neutrons from the Technical University of Munich (TUM) research neutron source for non-destructive detection

New clues to the conundrum of mother-to-child HIV transmission
Each year over 150,000 infants worldwide are infected with HIV in the womb, at birth, or through breastfeeding. Why transmission occurs in some cases but not others has long been a mystery, but now a team led by Weill Cornell Medicine and Duke University scientists has uncovered an important clue, with implications for how to eliminate infant HIV infections.

A new perspective on the genomes of archaic humans
Researchers examined 14,000 genetic differences between modern humans and our most recent ancestors at a new level of detail. They found that differences in gene activation – not just genetic code – could underlie evolution of the brain and vocal tract.

Cleaner water through corn
Corn is America's top agricultural crop, and also one of its most wasteful. About half the harvest — stalks, leaves, husks, and cobs — remains as waste after the kernels have been stripped from the cobs. These leftovers, known as corn stover, have few commercial or industrial uses aside from burning. A new article describes an energy-efficient way to put corn stover back into the economy by tran

Researcher questions whether powered flight appeared on non-avialan dinosaurs
Powered flight in animals—that uses flapping wings to generate thrus—is a very energetically demanding mode of locomotion that requires many anatomical and physiological adaptations. In fact, the capability to develop it has only appeared four times in the evolutionary history of animals: On insects, pterosaurs, birds and bats.

China Is Working on What Looks Like a Clone of SpaceX's Starship
Starship Clone Back in 2017, SpaceX showed off its vision for the future: an end-to-end transportation system that can get you anywhere on the globe in a matter of a couple of hours by rocketing into near space on board what was called the "BFR." Four years later, and that vision of what is now known as the Starship system has made significant progress, with SpaceX focusing on getting the first a

A new way of rapidly counting and identifying viruses
A professor has introduced a new concept for rapidly analyzing for the presence of a virus from colds to coronaviruses. However, although the concept can identify that someone has a type of coronavirus for example, it would not be able to determine the type of coronavirus, or variants. Additional tests would still be required to find out the specific virus someone was infected with.

Scientists Alarmed by Lab-Grown Human-Animal Hybrids
Earlier this month, scientists announced that they'd successfully created part-human, part-monkey hybrids by injecting human stem cells into six-day-old macaque embryos. The experiment was shockingly successful compared to past attempts to create hybrids — also called chimeras — according to the study , which was published in the journal Cell . Aside from the abstract benefits of scientific disco
