Research examines dentists' role in painkiller abuse

A recent study reveals that dentists play a significant role in opioid drug abuse, with many not aware of the risks or proper prescribing guidelines. The research calls for dentists to take steps to reduce leftover painkillers, discuss medication use with patients, and utilize prescription monitoring programs to prevent misuse.

Is governmental investment in industrial R&D paying off?

A study by Kalman Geyer found that companies participating in the EUREKA program experienced a 28% annual increase in sales volume and a 20% or more annual increase in employment, compared to similar non-participating companies. The survey revealed significant results on the impact of EUREKA participation in both parameters.

Big hole filled in cloud research

Research suggests planes may induce odd-shaped holes or canals into clouds, potentially increasing precipitation near airports with frequent cloud cover. This inadvertent seeding process works similarly to intentional cloud seeding and may require more frequent de-icing for planes.

UT Southwestern pediatric urologist develops procedure to eliminate scarring in kidney surgeries

A new minimally invasive procedure called hidden incision endoscopic surgery (HIdES) eliminates visible scarring in kidney surgeries. The technique, developed by Dr. Patricio Gargollo, offers greater technical flexibility than laparoscopic surgery and has been shown to provide higher satisfaction rates among patients.

Foods with baked milk may help build tolerance in children with dairy allergies

A recent study conducted at Mount Sinai School of Medicine found that introducing baked milk products into the diets of children with milk allergies accelerated the rate at which they outgrew their allergy. After five years, 47% of children in the experimental group could tolerate unheated milk products, compared to 22% in a control gr...

Auto-pilots need a birds-eye view

Scientists from Harvard University trained pigeons to fly through an artificial forest, gaining insights into their navigation methods that could inform auto-pilot technology design. The birds' ability to assess obstacles and choose straight routes could lead to more efficient and energy-saving navigation systems.

Breaking Kasha's rule

Researchers at Berkeley Lab have discovered a unique luminescence property in tetrapod nanocrystals that breaks Kasha's rule. The cadmium-selenide/cadmium-sulfide core/shell tetrapods emit light from multiple excited states, showing promising potential for optical sensing and LED applications.

Evolution of sport performances follows a physiological law

Research by Berthelot and Len found that athlete performance follows an exponential growth curve to a peak before declining irreversibly between the ages of 20 and 30. This pattern is also observed in other physiological parameters such as lung function and cognitive skills, suggesting a universal law governing human capability evolution.
