Y chromosome : Genes Linked To Ageing And Lifespan Regulation
Researchers have discovered that the Y chromosome possesses genes linked to ageing and lifespan regulation.

Distributed Denial-of-Service (DDoS) Attack:
Microsoft recently acknowledged that the series of service disruptions experienced by users of Microsoft Azure, OneDrive and Outlook were the result of a major distributed denial of service (DDoS) attack.
- Distributed Denial-of-Service (DDoS) Attack is a malicious attempt to disrupt the normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic.
- DDoS attacks achieve effectiveness by utilizing multiple compromised computer systems as sources of attack traffic.
- Exploited machines can include computers and other networked resources such as IoT devices.
- Unlike other kinds of cyberattacks, DDoS assaults don’t attempt to breach your security perimeter. Rather, a DDoS attack aims to make your website and servers unavailable to legitimate users.
- DDoS can also be used as a smokescreen for other malicious activities and to take down security appliances, breaching the target’s security perimeter.
- DDoS attacks are carried out with networks of Internet-connected machines.
- These networks consist of computers and other devices (such as IoT devices) which have been infected with malware, allowing them to be controlled remotely by an attacker.
- These individual devices are referred to as bots(or zombies), and a group of bots is called a botnet.
- Once a botnet has been established, the attacker is able to direct an attack by sending remote instructions to each bot.
- When a victim’s server or network is targeted by the botnet, each bot sends requests to the target’s IP address, potentially causing the server or network to become overwhelmed, resulting in a denial of service to normal traffic.
Ground Water Extraction On Earth’s Spin: Findings
A recent study published in Geophysical Research Letters has shed light on the significant impact of Groundwater Extraction on Earth’s Rotational Axis and its contribution to global sea-level rise.
- Researchers analyzed changes in the drift of Earth’s rotational pole and water movement first, by accounting for just ice sheets and Glaciers and then by adding different groundwater redistribution scenarios.
Key Findings of the Study:
- Groundwater pumping has tilted Earth nearly 80 centimeters east between 1993 and 2010 alone.
- The water circulated across the planet determines how mass is distributed.
- Between 1993 and 2010, people pumped 2,150 gigatons of groundwater, or more than 6 millimeters of sea level increase.
- Excessive groundwater pumping has caused the Earth’s pole to drift at a rate of 4.36 centimeters per year between 1993 and 2010, making it the climate-related factor with the greatest impact on polar motion.
- Redistributing water from the mid-latitudes significantly influences polar drift; therefore, the location of redistribution determines polar drift.
- During the study period, most redistribution occurred in western North America and northwestern India — both located at mid-latitudes.
- Groundwater pumping contributed to a sea-level rise of 6.24 mm during the mentioned period.
- Pumping from mid latitude areas, such as northwest India and western North America, has the most substantial influence on Earth’s axis drift.
- The rotational pole normally changes by several metres within about a year, so changes due to groundwater pumping don’t run the risk of shifting seasons.
- But on geologic time scales, polar drift can have an impact on climate.
Women 20 Summit 2023:
