According to a new study from the Graziano Lab at Princeton University, US, there has been a sharp drop in the number of US college students who believe that some form of invisible beams are emitted form peoples’ eyes when they look at something (k.a. extramission). Their research suggests that the figure could now be […]

Laser beams shooting out of cows’ eyes, in Scotland
“Laser beams shooting out of cows’ eyes could be a step toward better biometric security, less easily forged banknotes, and improved sensors, according to a team of Scottish scientists,” says a report in IEEE Spectrum. Technical details are sprinkled throughout the extent of a paper in the journal Nature Communications. The researchers are at the […]
Mosquito Neural Netting: To identify the sound of a single mosquito
A complex new attack on mosquitoes, sort of, is outlined in this new study about identifying the sound of a single mosquito: “Mosquito Detection with Neural Networks: The Buzz of Deep Learning,” Ivan Kiskin, Bernardo Pérez Orozco, Theo Windebank, Davide Zilli, Marianne Sinka, Kathy Willis, Stephen Roberts, arXiv:1705.05180, May 15, 2017. The paper points out, especially, a limitation […]
Report of the scientific investigation: Can farts be lit on fire by a laser?
There was indeed a scientific investigation after the (widely reported) fire that ignited during a patient’s cervical conization procedure at the University of Tokyo Hospital, causing “a wide range of burns [to the] thighs [and] rear” to the patient. That scientific report is lavishly illustrated with photographs. To determine whether the accident could have been caused by an […]
Playing with pigs and lasers
Pigs, like humans, can get bored. Perhaps they’d like to play a game to amuse themselves? Even better, with interacting humans? A project designed to examine such possibilities is underway at Hogeschool voor de Kunsten Utrecht and Wageningen University Livestock Research Department in The Netherlands. It’s called ‘Playing With Pigs’ and is “researching the complex […]
Boxes for rocks — their own story
Boxes for rocks grow from much thought and careful effort, what with the desire that each box fit snugly and well in enclosing a particular rock. Ann Macmillan, say those who know, “creates cardboard boxes for rocks that are designed to fit each rock’s individual surface. After 3D scanning them and unfolding the rock’s geometry, the […]
Perfecting the Schnitzel-Laser
Moti Fridman alerted us to the existence of the schnitzel-laser. Fridman wrote: “They showed how a laser can find by itself the correct phase to lase at in order to go through a thin chicken breast with no aberrations, when it is put inside the cavity. In a talk they called it the schnitzel-laser. This research shows beautifully the […]
Eyebrows Lasers Dangers
If one was contemplating methodologies for the permanent removal of one’s eyebrows, and one was inclined towards a laser – specifically a 755 nanometre Alexandrite laser – then one might be advised to think again. A 2011 case report in the medical journal Clinical Ophthalmology describes a scenario involving a 41-year-old man, who : “…presented […]
Voyeurs swooping beneath Nottingham
The good folks at the Nottingham Caves Survey marry spelunking, archaeology, laser scanning, and computer-generated-imagery to record and display some of the hidden wonders — caves and tunnels and other passageways — that statically wriggle and wander beneath the streets and buildings and hills of Nottingham, England. The video below is one of several they […]
