Animals, like us, experience a deterioration of memory in old age. A new study, however, indicates that cuttlefish are the first species in which this appears not to be the case.Continue ReadingCategory: Biology, ScienceTags: University of Cambridge, F… Continue reading Study suggests cuttlefish don’t experience age-related memory loss
I’m preparing for a computer security exam, and I found this question in previous exams
To create an authentication program, we write a check_auth function as
follows:
int check_auth(char *password) {
int auth_flag = 0;
size_t n… Continue reading code and memory safety issues
I am trying to understand buffer overread in my course in school. This code is an example from one of the lectures where buffer overread can be a problem. However, I do not understand how buffer overread can occur in this code.
In my knowl… Continue reading Buffer overread
In the late 19th century German psychologist Hermann Ebbinghaus published an influential book exploring memory and learning. Ebbinghaus was the first to chronicle a learning phenomenon which became known as the “spacing effect.”Continue ReadingCategory… Continue reading Neuroscientists discover how taking breaks while learning improves memory
I’m trying to write a blogpost on this challenge (it’s pretty basic, it should teach you about buffer overflows and ret2libc attacks).
The source code is the following:
#include <stdlib.h>
#include <unistd.h>
#include <stdio… Continue reading How does stack allocation work in this program? [closed]
A new study has found caffeine can be used to help bees locate specific flowers. The research suggests the drug enhances bee memory and makes them more efficient at homing in on certain targeted flowers.Continue ReadingCategory: Biology, ScienceTags: B… Continue reading Caffeine-boosted bees more efficiently home in on target flowers
In a recent Substack article ("The Insecurity Industry", 2021-07-26) Edward Snowden writes:
The vast majority of vulnerabilities that are later discovered and exploited by the Insecurity Industry are introduced, for technical re… Continue reading What does Snowden mean by "majority of vulnerabilities … are introduced, for technical reasons …, at the exact time the code is written"?
An intriguing new study from researchers in the United Kingdom is proposing an innovative method to treat age-related memory loss. The preclinical research shows memory decline in aging mice can be reversed by manipulating the composition of structures… Continue reading Preclinical study finds success in reversing age-related memory loss
A unique new imaging study compared brain activity of superagers learning novel information to youthful brains completing the same task. The results highlight exactly how some older adults can maintain good memory function, and directs researchers to b… Continue reading Superager study uncovers how aging brains maintain superior memory
Functionally, human faces basically all look the same – and yet, our brains are extremely fast at recognizing the faces of people important to us. Now, a new study has identified a previously unknown population of brain cells that may be hybrids of sen… Continue reading “Hybrid” brain cells found to recognize familiar faces faster
