A team of Japanese researchers from Kyushu University has made a groundbreaking discovery that could revolutionize the field of solar cells. By introducing chirality into molecular orientation, they were able to achieve a remarkable triplet yield of 133%, significantly improving energy transfer when absorbing light. This technique, known as singlet fission (SF), involves the absorption … Read more
A new study on left-handedness has revealed surprising insights into the cognitive abilities of individuals with this trait. Researchers at Oxford and London universities found that people with moderate handedness outperformed those with reversed asymmetry profiles in a pegboard task, which measures hand dominance. The study also discovered a link between social difficulties and autism … Read more
Scientists have made a breakthrough in fusion energy, a quest for limitless clean electricity that could revolutionize the world’s power supply. Researchers at Princeton Plasma Physics Laboratory found a way to prevent material on chamber walls from interfering with the reaction, allowing for more efficient and sustainable fusion energy. The problem faced by scientists was … Read more
A team of scientists led by Professor Neil Garg is redefining a fundamental principle in organic chemistry. Bredt’s rule, which has been a cornerstone of the field since 1924, may not be as unbreakable as thought. Bredt’s rule states that double bonds cannot exist at certain positions within bridged bicyclic molecules, known as olefins. However, … Read more
Cloudflare recently announced Access for Infrastructure SSH, a feature that replaces traditional SSH keys with short-lived certificates. This new option leverages BastionZero’s integration into Cloudflare One and reduces the complexity of managing SSH keys while enhancing security by substituting long-term SSH keys with temporary, ephemeral certificates. Traditionally, users generate an SSH key pair and gain … Read more
When it comes to building a database, Linux offers a simpler and more transparent alternative to relational databases driven by SQL. One of the simplest structured text formats is DSV (delimiter-separated values), which can be used to store data such as todo lists. In this article, we’ll explore how to create and use a database … Read more
Okta has issued an unusual security advisory update, revealing that under specific circumstances, an attacker could log in by only providing a username with a stored cache key from a previous successful authentication. The vulnerability is related to the Bcrypt algorithm used to generate the cache key for AD/LDAP DelAuth. According to Okta, this exploit … Read more
Okta, a digital security management company, has fixed a unusual bug in its software that could have allowed bad actors to log into accounts without entering passwords. The bug, which was present for approximately three months, would allow users to authenticate using only their username if it was 52 characters or longer. According to Okta’s … Read more
Okta, a leading authentication provider, has revealed a bizarre security vulnerability that allows users with long usernames (52 characters or more) to access protected accounts without knowing their passwords. The vulnerability was discovered on October 30 and resolved the same day in the affected product version of Okta AD/LDAP DelAuth. According to Okta’s security advisory, … Read more
