Woman uses Thallium to seek revenge from in-laws
Thallium
- It is globally known as the ‘poisoner’s poison’.
- It was discovered by Sir William Crookes in 1861.
- It is a metal belongs to the main Group 13 (IIIa, or boron group) of the periodic table.
- It was used historically as a rodenticide.
- Properties
- It is tasteless and odourless.
- It is a soft, heavy, and low-melting element of low tensile strength.
- It does not dissolve in water.
- It dissolves slowly in hydrochloric acid and dilute sulfuric acid and rapidly in nitric acid.
- It is found in trace amounts in the earth’s crust.
- This metal continues to oxidizeoxidise upon prolonged contact with air, generating a heavy nonprotective oxide crust.
- Trace amounts of thallium are present in sulfide ores of zinc and lead; in the roasting of these ores, the thallium becomes concentrated in the flue dusts, from which it is recovered.
- Applications: It is used in the manufacture of electronics, low temperature thermometers, optical lenses, and imitation precious jewels.

Cognitive Computing Market Share, Size, Trends Analysis, Report 2023-2028
Cognitive Computing
- Cognitive computing is the use of computerised models to simulate the human thought process in complex situations where the answers might be ambiguous and uncertain.
- It is an attempt to have computers mimic the way the human brain works.
- The goal is to create intelligent systems that can adapt and make decisions similar to the way humans would.
- To accomplish this, cognitive computing uses artificial intelligence (AI) and other underlying technologies, including the following:
- Expert systems.
- Neural networks.
- Machine learning.
- Deep learning.
- Natural language processing (NLP)
- Speech recognition.
- Object recognition.
- Robotics.
- It uses these processes in conjunction with self-learning algorithms, data analysis, and pattern recognition to teach computing systems.
- Cognitive computing applications analyse patterns and apply machine learning to replicate human capabilities such as deduction, learning, perception, and reasoning.
- Unlike traditional programmed systems, cognitive computing solutions can analyse large amounts of unstructured data from various sources and identify patterns and insights.
- They can interpret text, images, and speech and make connections across data. Over time, these systems continue to learn from their interactions and experiences.
- The learning technology can be used for sentiment analysis, risk assessments, and face detection.
- In addition, cognitive computing is particularly useful in fields such as healthcare, banking, finance, and retail.
New software tool provides a way for safer design of genome editing
- For about a decade, researchers have used the CRISPR technology for genome editing. However, there are some challenges in the use of CRISPR.
- The first challenge is that the phenotypic, or observable, effects caused by unexpected CRISPR dynamics are not quantitatively monitored.
- A second challenge is that the CRISPR technology generally depends on basic genomic data, including the reference genome. The reference genome is like a template that provides researchers with general information on the genome. Unexpected sequence editing with mismatches can occur. These off-target sites are always unexpected.
- The DANGER analysis overcomes these challenges and allows researchers to perform safer on- and off-target assessments without a reference genome.
- The discovery holds the potential for applications in medicine, agriculture, and biological research.
DANGER (Deleterious and ANticipatable Guides Evaluated by RNA-Sequencing)
- DANGER analysis is a new software tool that makes genome editing safer by overcoming limitations in current CRISPR technology.
- Unlike traditional methods that rely on a reference genome, DANGER works by conducting risk-averse on- and off-target assessments using RNA-sequencing data.
- It evaluates phenotypic effects based on gene expression changes caused by deleterious off-target sites.
- The software quantifies the phenotypic risk at the gene ontology level without the need for a reference genome.
- The tool successfully evaluated the phenotypic effects of gene editing in human cells and zebrafish brains.
- It can be performed on various organisms, personal human genomes, and atypical genomes created by diseases and viruses.
- The open-source nature of the software allows for its adaptation to different genome editing systems beyond CRISPR-Cas9.
Genome editing
- It is a method that lets scientists change the DNA of many organisms, including plants, bacteria, and animals.
- Editing DNA can lead to changes in physical traits, like eye colour, and disease risk.
- Scientists use different technologies to do this.
- These technologies act like scissors, cutting the DNA at a specific spot. Then scientists can remove, add, or replace the DNA where it was cut.
CRISPR-Cas9
- CRISPR is short for Clustered Regularly Interspaced Short Palindromic Repeats, which is a reference to the clustered and repetitive sequences of DNA found in bacteria, whose natural mechanism to fight some viral diseases is replicated in this gene-editing tool.
- Its mechanism is often compared to the ‘cut-copy-paste’, or ‘find-replace’ functionalities in common computer programmes.
- A bad stretch in the DNA sequence, which is the cause of disease or disorder, is located, cut, and removed — and then replaced with a ‘correct’ sequence. And the tools used to achieve this are not mechanical, but biochemical — specific protein and RNA molecules.
- The technology replicates a natural defence mechanism in some bacteria that uses a similar method to protect itself from virus attacks.
Pentagon rushes defences and advisers to Middle East as Israel''s ground assault in Gaza looms
Patriot Air Defence Missile System
- The Patriot (MIM-104), which stands for Phased Array Tracking Radar for Intercept on Target, is the S. Army’s most advanced air defense system.
- It is an all-weather surface-to-air missile defense system to counter tactical ballistic missiles, cruise missiles, and advanced aircraft.
- It was developed by Raytheon, an American multinational aerospace and defense conglomerate.
- The system was first used in combat during the 1991 Gulf War, with batteries protecting Saudi Arabia, Kuwait, and Israel, and was later used during the U.S. invasion of Iraq in 2003.
- It is in service with the US and allied countries, including Germany, Greece, Israel, Japan, Kuwait, the Netherlands, Saudi Arabia, South Korea, Poland, Sweden, Qatar, the United Arab Emirates, Romania, Spain, and Taiwan.
- Features:
- It is a mobile system that usually includes powerful radar, a control station, a power generator, launch stations, and other support vehicles.
- Depending on the version in use, the interceptor missiles can reach an altitude of more than 24 kilometres and hit targets up to 160 kilometres away.
- Its radar can track up to 50 targets and engage five of them at once.
- It is equipped with a track-via-missile (TVM) guidance system. Midcourse correction commands are transmitted to the guidance system from the mobile engagement control centre.
- A Patriot battery can need as many as 90 troops to operate and maintain it.
Mycena fungi are evolving to have living hosts
Mycena
- Mycena is a large genus of small saprotrophic mushrooms in the family Mycenaceae.
- The genus is now known to include about 500 species worldwide.
- Habitat: They can be found on decaying wood, leaf litter, or soil, and they often appear in clusters or small groups.
- Features:
- Most of the species are extremely small mushrooms, rarely exceeding a few centimeters in diameter and often only reaching diameters of a few millimeters.
- Majority of species are grey, brown, and white in color, while a few are brightly colored.
- They are characterized by a white spore print, a small conical or bell-shaped cap, and a thin, fragile stem.
- Most have a translucent and striate cap, which rarely has an incurved margin.
- These mushrooms have closely spaced, free, or attached gills that run down the stem. The gill color can be white, cream, or pinkish.
- Mycenas are hard to identify as species, and some are distinguishable only by microscopic features such as the shape of the cystidia.
- Some species are known to be edible, while some are known to contain toxins, but most of them are not known, as they are too small to be useful in cooking.
- Some species are bioluminescent, meaning they can emit a faint, greenish glow in low-light conditions.
