Predicting the next pandemic virus is harder than we think Posted: 20 Apr 2021 03:31 PM PDT The observation that most of the viruses that cause human diseases come from other animals has led some researchers to attempt 'zoonotic risk prediction' to second-guess the next virus to hit us. However, in a new essay, experts propose that these zoonotic risk predictions are of limited value and will not tell us which virus will cause the next pandemic. |

Reversal of blood droplet flight predicted, captured in experiments Posted: 20 Apr 2021 09:15 AM PDT To search for answers about how blood droplets from a gunshot wound can reverse direction while in flight, researchers explored the influence of propellant gases on blood backspatter. They report using numeric modeling to capture the behavior of gun muzzle gases and predict the reversal of blood droplet flight, which was captured experimentally. Their experiments also show the breakup of blood droplets, a future extension of their modeling efforts. |
Forensics puzzle cracked via fluid mechanical principles Posted: 20 Apr 2021 09:15 AM PDT A real-life forensic puzzle inspired researchers to explore the physics involved, and in Physics of Fluids, they present theoretical results revealing an interaction of the incoming vortex ring of propellant muzzle gases with backward blood spatter. A detailed analytical theory of such turbulent self-similar vortex rings was given by this group in earlier work and is linked mathematically to the theory of quantum oscillators. |
Stone skipping techniques can improve reentry of space vehicles Posted: 20 Apr 2021 09:15 AM PDT Scientists reveal several key factors that influence the number of bounces a skipping stone will undergo when hitting the water. The study involved theoretical modeling and an experimental setup using a model stone to gather data in real time and that allowed a motor to apply a controlled spin to the disk prior to launch. The investigators found that vertical acceleration and the spin direction influence the result. |
AI agent helps identify material properties faster Posted: 20 Apr 2021 09:15 AM PDT Artificial intelligence (AI) can analyze large amounts of data, such as those generated when analyzing the properties of potential new materials, faster than humans. However, such systems often tend to make definitive decisions even in the face of uncertainty; they overestimate themselves. An international research team has stopped AI from doing this: the researchers have refined an algorithm so that it works together with humans and supports decision-making processes. As a result, promising new materials can be identified more quickly. |
A gene finding links severe canine juvenile epilepsy to mitochondrial dysfunction Posted: 20 Apr 2021 09:15 AM PDT Researchers found a cause for severe epilepsy resulting in death in Parson Russell Terrier puppies at a few months of age. A change in the PITRM1 gene can lead to a dysfunction of mitochondria, the cellular energy pumps. Concurrently, amyloid-beta accumulation and widespread neurodegeneration associated with Alzheimer's disease were identified in the puppies' brains. Changes to the PITRM1 gene in humans also cause a severe but slowly progressing brain disease. |

New catalyst for lower CO2 emissions Posted: 20 Apr 2021 09:15 AM PDT Perovskites have so far been used for solar cells, as anode materials or electronic components rather than for their catalytic properties. Now scientists have succeeded in producing a special perovskite that is excellently suited as a catalyst for converting CO2 into other useful substances, such as synthetic fuels. The new perovskite catalyst is very stable and also relatively cheap, so it would be suitable for industrial use. |

Our attention is captured by eye-glance Posted: 20 Apr 2021 06:29 AM PDT Researchers looked at the way we process human gaze, focusing on the estimation of the temporal duration of social interactions. They discovered that when we make eye contact with another person, our attention is solicited, causing a distortion in our temporal perception: time seems shorter than it really is. These results will make it possible to develop a diagnostic tool to evaluate the mechanisms at work in people who are sensitive to social gaze. |

Flushing a public toilet? Don't linger, because aerosolized droplets do Posted: 20 Apr 2021 06:28 AM PDT Because COVID-19 has been detected in urine and stool samples, public restrooms can be cause for concern. Researchers measured droplets generated from flushing a toilet and a urinal in a public restroom and found a substantial increase in the measured aerosol levels in the ambient environment with the total number of droplets generated in each flushing test ranging up to the tens of thousands. Due to their small size, these droplets can remain suspended for a long time. |
