Nobel Prize in Physiology or Medicine 2024

The Nobel Prize in Physiology or Medicine 2024 given to Victor Ambros (Affiliation at the time of the award: UMass Chan Medical School, Worcester, MA, USA) and Gary Ruvkun (Affiliation at the time of the award: Massachusetts General Hospital, Boston, MA, USA; Harvard Medical School, Boston, MA, USA)  for the discovery of microRNA and its role in post-transcriptional gene regulation.



The information stored within our chromosomes can be likened to an instruction manual for all cells in our body. Every cell contains the same chromosomes, so every cell contains exactly the same set of genes and exactly the same set of instructions. Yet, different cell types, such as muscle and nerve cells, have very distinct characteristics. How do these differences arise? The answer lies in gene regulation, which allows each cell to select only the relevant instructions. This ensures that only the correct set of genes is active in each cell type.

ADB projects India’s growth for 2024 - 25

The Asian Development Bank (ADB) has projected India’s economic growth at 7% for the financial year 2024 and 7.2% for FY2025, stating that the country’s economy remains strong. ADB’s Country Director for India, Mio Oka, said that India has displayed resilience in the face of global geopolitical challenges and is set for steady expansion. Oka added that improvements in agriculture are expected to boost rural spending, complementing the robust performance of the industry and services sectors.

In its September edition of the Asian Development Outlook (ADO), ADB reported that a favorable monsoon across most regions of India is expected to lead to strong agricultural output, positively impacting the rural economy in FY2024. Additionally, the report holds an optimistic view of the industry and services sectors, private investments, and urban consumption for both FY2024 and FY2025.

The new government policy offering employment-linked incentives to workers and firms is expected to increase labor demand and support job creation beginning in FY2025. The report says “With the government’s fiscal consolidation efforts, central government debt is projected to decrease from 58.2% of GDP in FY2023 to 56.8% in FY2024. The general government deficit, which includes state governments, is expected to fall below 8% of GDP in FY2024.”

However, consumer inflation is expected to rise to 4.7% in FY2024 due to higher food prices, despite an increase in agricultural output. ADB noted that inflation has kept the Reserve Bank of India (RBI) from lowering policy interest rates. Should agricultural supply improve and food prices moderate, the central bank may consider easing interest rates in FY2024, which could facilitate credit expansion.

Built on the Microsat/IMS-1 bus, EOS-08 carries three payloads: Electro Optical Infrared Payload (EOIR), Global Navigation Satellite System-Reflectometry payload (GNSS-R), and SiC UV Dosimeter. The EOIR payload is designed to capture images in the Mid-Wave IR (MIR) and Long-Wave IR (LWIR) bands, both during the day and night, for applications such as satellite-based surveillance, disaster monitoring, environmental monitoring, fire detection, volcanic activity observation, and industrial and power plant disaster monitoring. The GNSS-R payload demonstrates the capability of using GNSS-R-based remote sensing for applications such as ocean surface wind analysis, soil moisture assessment, cryosphere studies over the Himalayan region, flood detection, and inland waterbody detection. Meanwhile, the SiC UV Dosimeter monitors UV irradiance at the viewport of the Crew Module in the Gaganyaan Mission and serves as a high-dose alarm sensor for gamma radiation.

The spacecraft mission configuration is set to operate in a Circular Low Earth Orbit (LEO) at an altitude of 475 km with an inclination of 37.4°, and has a mission life of 1 year. The satellite has a mass of approximately 175.5 kg and generates power of around 420 W. It interfaces with the SSLV-D3 launch vehicle. EOS-08 marks a significant advancement in satellite mainframe systems such as an Integrated Avionics system, known as the Communication, Baseband, Storage, and Positioning (CBSP) Package, which combines multiple functions into a single, efficient unit. This system is designed with cold redundant systems using commercial off-the-shelf (COTS) components and evaluation boards, supporting up to 400 Gb of data storage. Additionally, the satellite includes a structural panel embedded with PCB, an embedded battery, a Micro-DGA (Dual Gimbal Antenna), an M-PAA (Phased Array Antenna), and a flexible solar panel, each serving as key components for onboard technology demonstration.

The satellite employs a miniaturized design in its Antenna Pointing Mechanisms, capable of achieving a rotational speed of 6 degrees per second and maintaining a pointing accuracy of ±1 degree. The miniaturized phased array antenna further enhances communication capabilities, while the flexible solar panel incorporates a foldable solar panel substrate, GFRP tube, and CFRP honeycomb rigid end panel, offering improved power generation and structural integrity. A pyrolytic graphite sheet diffuser plate, known for its high thermal conductivity of 350 W/mK, reduces mass and finds application in various satellite functions. Furthermore, the EOS-08 mission adopts a new method of integrating housekeeping panels using a hinge-based fixture, significantly reducing the duration of the Assembly, Integration, and Testing (AIT) phase.

Incorporating additional novel schemes, the EOS-08 mission improves satellite technology through X-band data transmission, utilizing pulse shaping and Frequency Compensated Modulation (FCM) for X-Band data transmitters. The satellite’s battery management system employs SSTCR-based charging and bus regulation, sequentially including or excluding strings at a frequency of 6 Hz. The mission’s indigenization effort is evident in its solar cell fabrication processes and the use of a Nano-Star Sensor for Microsat Applications. Additionally, the inertial system benefits from reaction wheel isolators that attenuate vibrations and a single antenna interface is utilized for TTC and SPS applications. Thermal management is enhanced using materials such as AFE BGA, Kintex FPGA, Germanium Black Kapton, and STAMET (Si-Al Alloy) Black Kapton to handle the thermal properties of COTS components. The mission also incorporates an auto-launch pad initialization feature, further demonstrating its commitment to innovative mission management.
