• The Cretaceous Period, spanning from approximately 145 to 66 million years ago, represents the third and final epoch of the Mesozoic Era.
• It is characterized by significant geological and biological events.
• The climate was generally warm, and the world's continents were positioned closer to their present locations.
• The Cretaceous witnessed the proliferation of diverse and iconic dinosaurs, including the formidable Tyrannosaurus rex and the enormous herbivorous sauropods.
• Additionally, flowering plants, or angiosperms, experienced a remarkable evolutionary expansion during this period, transforming terrestrial ecosystems.
• Towards the end of the Cretaceous, a catastrophic event, possibly a large asteroid impact, led to the mass extinction of dinosaurs and numerous other species, marking the boundary between the Cretaceous and the subsequent Paleogene Period.
• This extinction event profoundly shaped the course of Earth's biological evolution.

The government has warned top social media and internet companies that their platforms may be temporarily suspended and even be ordered blocked in case they are unable to tackle the menace of deepfakes.

What are Deepfakes?

• The term "deepfake" combines the concepts of deep learning with the fabrication of content.
• Deepfakes involve the creation of synthetic images and audio using machine-learning algorithms, intending to disseminate misleading content by replacing a real person's appearance, voice, or both with artificially generated likenesses or voices.
• These manipulated creations can either depict nonexistent individuals or simulate real people engaging in actions or utterances they never did.
• Originating in 2017, the word "deepfake" emerged when a Reddit user named "deepfakes" shared explicit videos featuring celebrities.
• The process of crafting deepfakes utilizes machine learning models employing neural networks to manipulate visual and auditory elements.
• To generate a convincing deepfake video, creators train the neural network on extensive real footage of the targeted person, facilitating a realistic understanding of their appearance from various angles and lighting conditions.
• This trained network is then combined with computer graphics to overlay the person onto a different actor.
• Regrettably, this technology is increasingly exploited for malicious purposes, including scams, celebrity impersonation, election interference, social engineering, disinformation attacks, identity theft, and financial fraud.
• The distinguishing factor of deepfakes lies in their challenging detection due to their sophisticated nature.

Spooked by the strong growth in unsecured loans to consumers, the Reserve Bank of India (RBI) has increased the cost of funds for banks and non-bank financial companies (NBFCs), by increasing the risk weight of such loans.

What are Risk Weights?

• Every rupee lent by the bank is a cost or has an implication on its capital position.
• Depending on the nature of the loan and the inherent risk associated with it, risk weights are attributed.
• Banks have to ensure that their capital is enough to cover these risk-weighted assets.
• Total assets as disclosed in the financials and total risk-weighted assets are different things.
• Each asset class has varying risk weights.
• For instance, risk weights for home loans could range from 50 percent to 75 percent, for gold loans it is 75 percent.
• Corporate loans are charged 100 percent given the risk they carry.

How do they affect borrowers?

• Lower the risk weight, and lower the rate of interest. This is the thumb rule.
• Therefore, risk weights impact borrowers indirectly and are felt through the pricing of loans.
• For instance, home loans have the lowest interest rate among retail products because lower risk weights allow banks to pass on the advantage of capital consumption.
• Personal loans and credit cards have the highest interest rate because of their tenure and charge on capital.

A team of researchers from the Indian Institute of Technology (IIT), Ropar has found the presence of tantalum, a rare metal, in the Sutlej river sand in Punjab.

What is Tantalum?

• Tantalum is a rare metal with the atomic number 73.
• Tantalum was first discovered by Anders Gustaf Ekenberg, a Swedish chemist, in 1802.
• It has been named after a Greek mythological figure Tantalus.

Properties:

• It’s grey, heavy, very hard, and one of the most corrosion-resistant metals in use today.
• It possesses high corrosion resistance because when exposed to air, it forms an oxide layer that is extremely difficult to remove, even when it interacts with strong and hot acid environments.
• When pure, tantalum is ductile, meaning it can be stretched, pulled, or drawn into a thin wire or thread without breaking.
• Moreover, it “is almost completely immune to chemical attack at temperatures below 150°C, and is attacked only by hydrofluoric acid, acidic solutions containing the fluoride ion, and free sulphur trioxide.
• Notably, tantalum also has an extremely high melting point, exceeded only by tungsten and rhenium.

Applications:

• Tantalum is most prominently used in the electronic sector.
• The capacitors made from tantalum are capable of storing more electricity in smaller sizes without much leakage than any other type of capacitor.
• This makes them ideal for use in portable electronic devices such as smartphones, laptops, and digital cameras.
• As tantalum has a high melting point, it is frequently used as a substitute for platinum, which is more expensive.
• The rare metal is also used to make components for chemical plants, nuclear power plants, aeroplanes, and missiles.
• Tantalum does not react with bodily fluids and is used to make surgical equipment and implants, like artificial joints.

In a recent landmark study, scientists reported successfully generating a live chimaera in non-human primates

About Chimaeras:

• A genetic chimaera is a single organism made up of cells from more than one distinct genotype (or genetic makeup).
• Examples of varying degrees of chimerism exist in the animal kingdom.
• For instance, the half-sider budgerigar, a common pet parakeet, displays different colors on each side of its body due to chimerism.
• In anglerfish, the male fuses with the female, eventually being absorbed, creating a single animal with a merged genetic makeup.
• Marine sponges are known to have up to four distinct genotypes in one organism.
• In humans, natural chimaeras occur when the genetic material in one cell changes, leading to a clonal population of cells different from the rest.
• Fusion of two fertilized zygotes early in embryonic development can result in a condition where two genetic makeups coexist in a single individual.
• Chimerism can also arise from twin or multiple pregnancies evolving into a single fetus or a twin fetus being absorbed into a singleton.

Recently, an international team of scientists found a new mysterious layer called the E prime layer on the outer part of the Earth's core.

About the E Prime Layer:

• Before, it was thought that there's only a small exchange of materials between the Earth's core and mantle.
• However, experiments showed that when water reaches the boundary between the core and mantle, it reacts with silicon in the core and creates silica.

Development of this Layer:

• New research proposes that over billions of years, tectonic plates carrying surface water transported it deep into the Earth.
• When this water reaches about 1,800 miles below the surface at the core-mantle boundary, it triggers significant chemical changes, affecting the core's structure.
• Scientists observed that under high pressure, subducted water chemically reacts with core materials.
• This reaction forms a hydrogen-rich, silicon-depleted layer on the outer core, resembling a film.
• Silica crystals produced in this process rise and mix into the mantle, impacting the overall composition.
• Changes in the liquid metallic layer could potentially lead to reduced density and altered seismic characteristics, consistent with anomalies detected by seismologists.

Importance of this Discovery:

• This finding deepens researchers' understanding of the Earth's internal workings, revealing a more extensive and complex global water cycle than previously known.
• The altered core layer has significant implications for the interconnected geochemical processes that link surface water cycles with the deep metallic core.

Atmospheric Waves Experiment is a first-of-its-kind NASA experimental attempt aimed at studying the interactions between terrestrial and space weather.

What is the Atmospheric Waves Experiment (AWE)?

• AWE is a first-of-its-kind NASA experimental attempt aimed at studying the interactions between terrestrial and Space weather.
• Planned under NASA’s Heliophysics Explorers Program, the $42 million mission will study the links between how waves in the lower layers of the atmosphere impact the upper atmosphere, and thus, Space weather.
• AWE will be launched and mounted on the exterior of the Earth-orbiting International Space Station (ISS).
• From the vantage point, it will look down at the Earth and record the colourful light bands, commonly known as airglow.
• It will try to understand the combination of forces that drive the Space weather in the upper atmosphere.
• “AWE could open a new window of study, wherein scientists are attempting to understand if Space weather is affected by terrestrial and bottom-up forces.
• It will measure the airglow at mesopause (about 85 to 87 km above the Earth’s surface), where the atmospheric temperatures dip to minus 100 degrees Celsius.
• At this altitude, it is possible to capture the faint airglow in the infrared bandwidth, which appears the brightest enabling easy detection.
• AWE will be able to resolve waves at finer horizontal scales than what satellites can usually see at those altitudes, which is part of what makes the mission unique.
• The health of the ionosphere, whose lower layers sit at the edge of Space, is important for maintaining seamless communication.

Researchers have found "compelling evidence" supporting the existence of the uncommon nitrogen-9 isotope. This discovery challenges previous interpretations and provides a fresh perspective on subatomic structures.

About Nitrogen-9 Nucleus:

• Nitrogen-9 is a radioactive isotope of nitrogen.
• This means that it is unstable and will eventually decay into a different isotope of nitrogen or a different element.
• It is considered unusual because it has an uncommon combination of seven protons and two neutrons (7:2) in its atomic nucleus.
• This creates an unusually high ratio of protons to neutrons.
• Generally, elements have a balanced ratio for stability, but Nitrogen-9’s high proton content makes it less stable, challenging the conventional stability thresholds.
• This oddity raises questions about its existence in this state and how it maintains stability, introducing complexity to our understanding of atomic nuclei.
• The reason for nitrogen-9's short half-life is that the strong force, which is responsible for holding nuclei together, is not strong enough to overcome the Coulomb repulsion between the positively charged protons in the nitrogen-9 nucleus.
• The discovery of nitrogen-9 is a major breakthrough in our understanding of nuclear physics.
• It showed that nuclei with very high proton-to-neutron ratios can exist, even if they are only for a very short time.
• This discovery has led to new research into the limits of nuclear stability and the role of nucleons (protons and neutrons) in holding nuclei together.

What is an Isotope?

• An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons in its atomic nucleus.
• This variance in neutron count results in different atomic masses for isotopes of the same element.
• Isotopes of an element share similar chemical properties but may exhibit differences in physical properties, such as stability and radioactivity.

Farmers in agricultural settings often identify freemartins by observing their physical and/or behavioral traits since these animals are unable to reproduce.

About Freemartins:

• A freemartin is an infertile female cattle with masculinized behavior and non-functioning ovaries.
• This condition is caused by the exchange of cells between female and male twins in utero.
• The male twin produces a hormone called anti-Müllerian hormone (AMH), which suppresses the development of the female reproductive tract.
• As a result, the female twin is born with an underdeveloped reproductive system and is unable to reproduce.
• Freemartinism occurs in about 90% of female cattle twins that share a placenta with a male twin.
• This is because the placentas of cattle twins are often fused together, allowing cells to move between the two fetuses.
• The fusion of placentas usually occurs between 40 and 120 days of gestation.
• In addition to being infertile, freemartins may also exhibit some masculine characteristics, such as a deeper voice, coarser hair, and a more muscular build.
• This is because they have been exposed to AMH from their male twin.
• There is no treatment for freemartinism, as the animal is infertile and cannot produce offspring.
• However, freemartins can still be used for other purposes, such as meat production or draft work.

As per the 2023 State of the Cryosphere report, the anticipated disappearance of almost all tropical glaciers, a significant majority of mid-latitude glaciers, and polar regions is expected, even if global efforts successfully limit the rise in temperatures to 2 degrees Celsius above preindustrial levels.

About the State of the Cryosphere Report 2023:

• The State of the Cryosphere Report annually assesses the condition of Earth's snow and ice regions, and has been reviewed and endorsed by over 60 leading cryosphere scientists.
• This report is published by The International Cryosphere Climate Initiative (ICCI.)
• The cryosphere is a term for the regions of our globe that are covered in ice and snow – either seasonally or year-round.
• The Report describes how a combination of melting polar ice sheets, vanishing glaciers, and thawing permafrost will have rapid, irreversible, and disastrous impacts worldwide.

Key findings in the report on the impact of 2°C of warming include:

• Ice sheets: nearly all of Greenland, much of West Antarctica, and even vulnerable portions of East Antarctica will be triggered to very long-term, inexorable sea-level rise.
• Glaciers: extensive, irreversible ice loss from the world’s glaciers in many major river basins, with some disappearing entirely.
• As glaciers melt, risks of catastrophic events such as landslides, sudden ice shears, and glacial lake outburst floods increase.
• Sea ice: extensive sea ice loss at both poles, with severe feedback to global weather and climate.
• By 2°C, the Arctic Ocean will be sea ice-free in summer every year, potentially for several months.
• Permafrost: extensive permafrost thaw and resulting greenhouse gas emissions will cause temperatures to continue to rise, even once human emissions reach zero.
• At 2°C, annual total permafrost emissions (both CO2 and methane) would total the size of the entire European Union’s emissions from 2019.
• Polar ocean acidification: year-round, permanent corrosive ocean acidification conditions in many regions of Earth’s polar and near-polar seas.
• Shell-building animals and commercial fisheries that rely on them in the food chain may not survive.

About International Cryosphere Climate Initiative (ICCI):

• It was formed in 2009 following COP-15 in Copenhagen
• ICCI is a network of senior policy experts and researchers working with governments and organizations to create, shape, and implement initiatives designed to preserve as much of the Earth’s cryosphere as possible.
• ICCI programs target the unique climate dynamics at work in the cryosphere, while at the same time lending increased urgency to global climate efforts aimed at CO2 and other greenhouse gases by communicating the unexpected rapidity and global implications of cryosphere warming.

Recently, scientists have discovered the inside structure of the enigmatic dwarf planet Eris.

About Dwarf Planet Eris:

• This new dwarf planet is the largest object found in orbit around the sun since the discovery of Neptune and its moon Triton in 1846.
• It was discovered on Jan. 5, 2005, and It is larger than Pluto, discovered in 1930.
• Like Pluto, the new dwarf planet is a member of the Kuiper belt, a swarm of icy bodies beyond Neptune in orbit around the sun.
• Eris is named for the ancient Greek goddess of discord and strife.
• The surface of Eris is extremely cold, so it seems unlikely that life could exist there.
• With a radius of about 1,163 kilometers, Eris is about 1/5 the radius of Earth.
• Eris, like Pluto, is a little smaller than Earth's Moon.
• Eris takes 557 Earth years to make one trip around the Sun.
• As Eris orbits the Sun, it completes one rotation every 25.9 hours, making its day length similar to ours.
• Moons: Eris has a very small moon called Dysnomia.
• Dysnomia has a nearly circular orbit lasting about 16 days.
• Eris most likely has a rocky surface similar to Pluto.
• Atmosphere: The dwarf planet is often so far from the Sun that its atmosphere collapses and freezes, falling to the surface as snow.

Recently, Visa has highlighted that the primary advantage of tokenization is a decreased risk of data breaches.

What is Card-on-File Tokenisation?

• Tokenisation is a process where the cardholder’s original card number, one which is written on the card and is extensively used for transactions and card identification, is replaced with a surrogate term called ‘token.’
• This process allows enhanced card protection by converting the customers’ card numbers into tokens.
• The exchange of tokens happens between the token requestor and the network, which empowers customers to receive a secure and reliable online payment experience.
• All relationship evidence of such exchange between token and crucial card information is securely saved in a vault that is only accessible to the card networks.
• Resultantly, the customers’ card details will be highly protected from online fraud and hackers.

How Does Card-on-File Tokenisation Work?

• When a customer makes a transaction by using their card at a tokenisation-based-authentication server:
• A credit/debit card is used for transactions at a POS device or an e-commerce website
• The tokenisation system receives and interprets the credit card number
• The tokenisation system goes on to replace the original credit card number with a 16-digit random character token for security
• The tokenisation system then provides the converted 16-digit random token number to the e-commerce marketplace and replaces the user’s credit card number with the same in their system
• For instance, card number (example): 4018 2255 6984 7854 will be replaced with token number: 4325 5214 8574 6658.
• The tokenisation system is an important tool for separating crucial data in ecosystems and databases while also offering enhanced card protection to cardholders.

The UK's medicines regulator has granted approval for the world's first gene therapy treatment for sickle cell disease.

What is Sickle Cell Disease?

• Sickle cell disease (SCD) is a blood disorder that is passed through the genes and results in abnormal hemoglobin.
• (Hemoglobin is a part of the red blood cells that carry oxygen through the body.)
• People with SCD have red blood cells that sickle or change shape when exposed to low oxygen levels in the cell.
• These sickled cells also become stiff and sticky compared to normal red blood cells.
• They can block blood flow, leading to tissue damage and pain.
• Over time, these blockages can lead to organ dysfunction and result in other serious medical complications.

Sickle Cell Disease Types

• There are several different forms of sickle cell disease, and it is different for each person.
• Hemoglobin SS, also known as sickle cell anemia
• Hemoglobin SC disease
• Hemoglobin sickle beta-thalassemia
• The most common and usually the most severe form is sickle cell anemia.
• The SCD type affects the severity and frequency of complications.
• The type of SCD also impacts the timing of complications.
• Some people have symptoms at a very young age while others will not show symptoms until adulthood.

Sickle Cell Disease Symptoms

• Anemia: Sickled blood cells are less able to carry oxygen, leading to anemia.
• Symptoms can include fatigue, weakness, dizziness, headache, shortness of breath and chest pain.
• Bone Pain: Decreased blood flow to the bones leads to periodic spikes in bone pain known as bone crises.
• SCD can also cause avascular necrosis, which is a breakdown of the bone and joint.
• Eye Disease or Blindness: Sickled blood cells can damage the fragile blood vessels in the back of the eye, leading to retina damage called retinopathy. This can lead to blindness.
• Infections: The spleen fails in SCD patients at a young age, decreasing the body’s ability to fight infections.
• Kidney Issues: Blood in the urine (papillary necrosis), frequent urination, kidney disease.

Treatments:

• A bone marrow transplant (stem cell transplant) can cure sickle cell disease.
• However, there are treatments that can help relieve symptoms, lessen complications, and prolong life.
• Gene therapy is also being explored as another potential cure. The UK recently became the first country to approve gene therapy treatment for sickle cell disease
