Researchers from the Wadia Institute of Himalayan Geology (WIHG), Dehradun, have traced the paleoclimatic history of the Indus River in Ladakh Himalaya. It was traced with the help of geometric data from overlapping gravels of channel fills.
♦ The researchers studied the discharge during periods in which the river experienced an increase in land elevation, due to the deposition of sediment and its incision.
♦ River Terraces are part of valley-wide aggradations, which has been studied extensively in Himalaya to understand the processes driving such a periodic increase in river valley land elevation and incision.
♦ The researchers studied the discharge during periods of established river aggradation and incision of the Indus River, Ladakh Himalaya over late Quaternary.
♦ The researchers used the geometric data from overlapping gravels of channel fills to calculate paleo discharges during net river aggradation at 47–23 ka (thousand years), and preserved slack water deposits (SWDs) at 14–10 ka to constrain paleo discharges that occurred during net river incision.
♦ The researchers also observed that the aggradation in the Himalayan rivers occurred in glacial-interglacial transient warm climatic conditions (33–21 ka and 17–14 ka) when the sediment budget in the rivers increased just after the glacial events.
♦ The recent study showed that aggradation took place in the Indus River when sediment to water ratio was higher during MIS-3 (Marine isotope stages (MIS).
♦ Marine oxygen-isotope stages are alternating warm and cool periods in the Earth's paleoclimate, deduced from oxygen isotope data reflecting changes in temperature derived from data from deep-sea core samples) and incision initiated when sediment to water ratio reduced during post-glacial climatically wet phase (early Holocene).

Researchers at the Department of Biotechnology’s National Centre for Cell Science (DBT-NCCS) in Pune discovered new biomolecules to fight drug resistance in Kala-azar exploring ways to tackle miltefosine resistance.
♦ The researchers worked with one of the species of Leishmania that causes infection, called Leishmania major. The researchers manipulated the transporter proteins in the species in a manner that would result in increased uptake of the drug and decrease in its being thrown out of the parasite’s body.
♦ The researcher used a computational method to design small molecules, called peptides, that could very specifically interact with the transporter proteins of L. major alone, and not interfere with human proteins in any way.
♦ The peptides were designed to modulate the transporter proteins “allosterically”, that is, by interacting with the protein molecule at a location other than the specific location where miltefosine binds to it.
♦ Teh outcomes of the research indicated that this approach could prove useful in the long run to develop novel therapeutics against drug-resistant Leishmania parasites.
Leishmaniasis is a tropical disease affecting almost 100 countries including India. It is caused by a parasite called Leishmania. It is transmitted through the bite of sandflies. There are three main forms of leishmaniasis are:
visceral, which affects multiple organs and is the most serious form of the disease
cutaneous causes skin sores and is the most common form
mucocutaneous causes skin and mucosal lesion
Visceral leishmaniasis is commonly known as Kala-azar in India. It is fatal in over 95% of the cases if left untreated. The only drug available against leishmaniasis is miltefosine. This drug is rapidly losing its effectiveness because of emerging resistance to this drug due to a decrease in its accumulation inside the parasite, which is necessary for the drug to kill the parasite.
Specific types of protein molecules called transporter proteins to play a major role in carrying miltefosine into and out of the parasite’s body, which comprises a single cell. A protein called ‘P4ATPase-CDC50’ is responsible for the intake of the drug by the parasite, and another protein, called ‘P-glycoprotein’, is responsible for throwing this drug out from within the parasite’s body.

Researchers from the Indian Institute of Technology (IIT-BHU) have developed an anti-microbial five-layered face mask. The face mask was aimed to address a few issues to combat novel coronavirus.
Disadvantage of common facemask:
The common face mask that is available in the market currently acts as a filter to stop the entry of microbes to oral and nasal airways but does not have any effect on the microbe stuck to the mask surface. This disadvantage of masks could be dangerous for medical and paramedical staff due to the presence of higher viral or bacterial load on their outer surface.
♦ This newly designed face mask can annihilate pathogenic microorganisms that are stuck to its outer surface. It will also limit the spread of secondary infections.
♦ The new face mask is stacked by different layers of nanometal conjugated with a protonated amine matrix.
♦ The anti-microbial face mask has 5 layers:
The first layer of the mask can degrade any type of Ribonucleic acid (RNA)
the second layer is anti-microbial
the third one is for air filtration
the fourth and fifth layers are comfortable layers, which will remain close to the nose and mouth.
♦ Copper and silver are de-transition elements that can degrade coronavirus and all the other members of the SARS virus. The mask is made with a combination of copper, copper oxides, silver, and activated charged silver, which can help degrade RNA.
♦ The mask has a hydrophobic surface on the outer layer to deflect water droplets containing the viruses.
