Calls for resilience training, more extra-curricular activities in schools to help prevent mental health disorders

A new study by Murdoch Children's Research Institute calls for increased support for student mental health, including training for educators and co-locating mental health clinicians. The researchers believe schools can play a crucial role in identifying at-risk children and providing prevention and early intervention strategies.

Increasing the accuracy of atomic force calculations with the space-warp coordinate transformation

Researchers developed a space-warp coordinate transformation (SWCT) method to accurately calculate atomic forces for elements with high atomic numbers. The study used quantum Monte Carlo simulations and found that the SWCT method reduces computational costs, resulting in more accurate calculations.

Light just got harder to hack

Researchers created a spatial and nonlinear encryption method for images using photorefractive crystals, increasing security in documents, currency, and credit cards. The method is immune to traditional phase-retrieval-based known-plaintext attacks and robust against machine learning-based cracking due to its image-dependence.

New research bites holes into theories about Megalodons

A new study using a two-dimensional drawing technique has found no general patterns in the fin and body shapes of five warm-blooded Lamniformes species to determine Megalodon's shape. The research challenges previous conclusions about the extinct shark's body form, suggesting that warm bloodedness does not make sharks differently shaped.

Latest study reveals no one still knows what the Megalodon really looked like

A new study by DePaul University researchers has found that all previously proposed body forms of the Megalodon shark are based on speculations. The lack of scientific evidence means that the public image of a massive, monstrous shark remains unchanged, while paleontologists continue to search for clues in the fossil record.
