Spectra is competing with the likes of Reliance JioFiber, Airtel Xstream broadband and ACT Fibernet, to name a few. And the company has some rather unique plans, in terms of what is bundled, depending on the duration you choose to pay for in one go.

Ministry of Science and Technology's Department of Biotechnology (DBT) Dr Renu Swarup says that based on the latest WHO consensus, Covid-19 as a 'lab release' theory is likely to be false.

A call about the blaze was received around 7.25 am on Sunday, following which 15 fire tenders were rushed to the spot.

The bacterial type VI secretion system (T6SS) secretes many toxic effectors to gain advantage in interbacterial competition and for eukaryotic host infection. The cognate immunity proteins of these effectors protect bacteria from their own effectors. PldB is a T6SS trans-kingdom effector in Pseudomonas aeruginosa that can infect both prokaryotic and eukaryotic cells. Three proteins, PA5086, PA5087 and PA5088, are employed to suppress the toxicity of PldB-family proteins. The structures of PA5087 and PA5088 have previously been reported, but the identification of further distinctions between these immunity proteins is needed. Here, the crystal structure of PA5086 is reported at 1.90 Å resolution. A structural comparison of the three PldB immunity proteins showed vast divergences in their electrostatic potential surfaces. This interesting phenomenon provides an explanation of the stockpiling mechanism of T6SS immunity proteins.

Quantum beats in fluorescence decay from Zeeman-split magnetic sublevels have been measured for helium Rydberg states excited by synchrotron radiation. The Zeeman quantum beats observed in this prototypical case were fitted with an equation from a theoretical formulation. It is proposed that Zeeman quantum beat measurement can be a useful way to simply evaluate the polarization characteristics of extreme ultraviolet light.

The open-source Python program PDB2INS is designed to prepare a .ins file for refinement with SHELXL [Sheldrick (2015). Acta Cryst. C71, 3–8], taking atom coordinates and other information from a Protein Data Bank (PDB)-format file. If PDB2INS is provided with a four-character PDB code, both the PDB file and the accompanying mmCIF-format reflection data file (if available) are accessed via the internet from the PDB public archive [Read et al. (2011). Structure, 19, 1395–1412] or optionally from the PDB_REDO server [Joosten, Long, Murshudov & Perrakis (2014). IUCrJ, 1, 213–220]. The SHELX-format .ins (refinement instructions and atomic coordinates) and .hkl (reflection data) files can then be generated without further user intervention, appropriate restraints etc. being added automatically. PDB2INS was tested on the 23 974 X-ray structures deposited in the PDB between 2008 and 2018 that included reflection data to 1.7 Å or better resolution in a recognizable format. After creating the two input files for SHELXL without user intervention, ten cycles of conjugate-gradient least-squares refinement were performed. For 96% of these structures PDB2INS and SHELXL completed successfully without error messages.

The structure of the Pseudomonas aeruginosa T6SS PldB immunity protein PA5086 is reported at 1.9 Å resolution. Comparison of PA5086 with its homologs PA5087 and PA5088 showed great similarities in sequence and structure, but vast divergences in electrostatic potential surfaces.

Yeast cells select the position of their new bud at the beginning of each cell cycle. The recruitment of the septins to this prospective bud site is one of the critical events in a complex assembly pathway that culminates in the outgrowth of a new daughter cell. Hereby, the septin-rods follow the high concentration of Cdc42_GTP that is generated by the focused localization of its GEF Cdc24. We show that shortly before budding Cdc24 not only activates Cdc42 but also transiently interacts with Cdc11, the septin subunit that caps both ends of the septin rods. Mutations in Cdc24 reducing the affinity to Cdc11 impair septin recruitment and decrease the stability of the polarity patch. The interaction between septins and Cdc24 thus reinforces bud assembly at sites where septin structures are formed. Once the septins polymerize into the ring, Cdc24 is found at the cortex of the bud and directs its further outgrowth from this position.

Although low-income households consume less energy than wealthier households, they are still keen to learn how to save energy, for both economic and environmental reasons. This is the conclusion of a recent Swedish study which explored the energy-related behaviour of residents on low incomes. It provides insights which could help inform energy-awareness campaigns targeted at this section of the population.

Electricity consumption fell by 22–27% in low-income households participating in an energy-efficiency programme in Cyprus, France, Malta and Spain, reports a new study. Participants were provided with a range of tools and information to help them curb their energy use, including smart meters and customised reports. The results confirm the value of tailoring information to specific demographic groups.

Motivation to practise fuel-efficient driving may be more influenced by environmental concerns than by financial benefits, research suggests. In promoting fuel efficiency, this survey of Dutch motorists highlights the power of providing feedback to drivers – both environmental and economic – on their behaviour.

A Crisil note said due to the aggressive play by the telcos, the number of subscribers has stagnated at 19 million since 2016. Till now, the lower speed 4G served the purpose for people due to affordable smartphones, it noted. "But now, subscriptions to fixed broadband, especially in the urban areas, have surged because millions are working from home...," it said.

The presence of disinfection by-products (DBPs) in drinking water is an emerging health concern. DBPs come in many classes and are chemically diverse, making them challenging to monitor. Swedish researchers have evaluated a new method for the simultaneous determination of a broader range of DBPs than typically possible using other available techniques. The method uses gas chromatography (a laboratory technique that separates and analyses vaporisable compounds in a mixture), together with a halogen-specific detector (XSD). Having been tested in real water samples from two municipal waterworks in Sweden, the method has been optimised for the simultaneous determination of a wide range of neutral DBPs.
