Unlocking the world of bacteria—researchers introduce new approach to make bacteria amenable to genetic engineering
Bacteria populate virtually every habitat on Earth, including within and on our own bodies. Understanding and engineering bacteria can lead to new methods for diagnosing, treating, and preventing infections. Additionally, it presents opportunities to.....»»
Stress testing pension funds—researchers present technique based on hidden Markov regime switching model
"We wanted to investigate how second pillar pension funds react to financial crises and how to protect them from the crises," says Kaunas University of Technology (KTU) professor Dr. Audrius Kabašinskas, who, together with his team, discovered a way.....»»
New calculation approach allows more accurate predictions of how atoms ionize when impacted by high-energy electrons
During electron-impact ionization (EII), high-energy electrons collide with atoms, knocking away one or more of their outer electrons. To calculate the probability that ionization will occur during these impacts, researchers use a quantity named the.....»»
Determining refractive index at relativistic speeds
If you studied advanced physics at high school, there's a good chance that you remember Snell's law, which states how a ray of light bends when it crosses a boundary between two media. According to this law, the ratio of the sines of the incident and.....»»
Wolves reintroduced to Isle Royale temporarily affect other carnivores, humans have influence as well
In a rare opportunity to study carnivores before and after wolves were reintroduced to their ranges, researchers from the University of Wisconsin–Madison found that the effects of wolves on Isle Royale have been only temporary. And even in the leas.....»»
