Around 3,500 Indians stranded abroad had been flown into India until the wee hours on Sunday as India’s Vande Bharat Mission motored ahead under what official sources described as regular high-level oversight. While eight flights landed across India on Saturday — Day 3 — an equal number was expected on Sunday. Around 2K will be arriving from the Maldives.

The chopper was inducted into service in March last year.

Beamline 8A (BL 8A) is an undulator-based soft X-ray beamline at Pohang Accelerator Laboratory. This beamline is aimed at high-resolution ambient-pressure X-ray photoelectron spectroscopy (AP-XPS), soft X-ray absorption spectroscopy (soft-XAS) and scanning photoemission microscopy (SPEM) experiments. BL 8A has two branches, 8A1 SPEM and 8A2 AP-XPS, that share a plane undulator, the first mirror (M1) and the monochromator. The photon beam is switched between the two branches by changing the refocusing mirrors after the monochromator. The acceptance angle of M1 is kept glancing at 1.2°, and Pt is coated onto the mirrors to achieve high reflectance, which ensures a wide photon energy range (100–2000 eV) with high resolution at a photon flux of ∼1013 photons s−1. In this article, the main properties and performance of the beamline are reported, together with selected experiments performed on the new beamline and experimental system.

The interoperability of chemical and biological crystallographic data is a key challenge to research and its application to pharmaceutical design. Research attempting to combine data from the two disciplines, small-molecule or chemical crystallography (CX) and macromolecular crystallography (MX), will face unique challenges including variations in terminology, software development, file format and databases which differ significantly from CX to MX. This perspective overview spans the two disciplines and originated from the investigation of protein binding to model radiopharmaceuticals. The opportunities of interlinked research while utilizing the two databases of the CSD (Cambridge Structural Database) and the PDB (Protein Data Bank) will be highlighted. The advantages of software that can handle multiple file formats and the circuitous route to convert organometallic small-molecule structural data for use in protein refinement software will be discussed. In addition some pointers to avoid being shipwrecked will be shared, such as the care which must be taken when interpreting data precision involving small molecules versus proteins.

The application of thermoelectrics for energy harvesting depends strongly on operational reliability and it is therefore desirable to investigate the structural integrity of materials under operating conditions. We have developed an operando setup capable of simultaneously measuring X-ray scattering data and electrical resistance on pellets subjected to electrical current. Here, operando investigations of β-Zn4Sb3 are reported at current densities of 0.5, 1.14 and 2.3 A mm−2. At 0.5 A mm−2 no sample decomposition is observed, but Rietveld refinements reveal increased zinc occupancy from the anode to the cathode demonstrating zinc migration under applied current. At 1.14 A mm−2 β-Zn4Sb3 decomposes into ZnSb, but pair distribution function analysis shows that Zn2Sb2 units are preserved during the decomposition. This identifies the mobile zinc in β-Zn4Sb3 as the linkers between the Zn2Sb2 units. At 2.3 A mm−2 severe Joule heating triggers transition into the γ-Zn4Sb3 phase, which eventually decomposes into ZnSb, demonstrating Zn ion mobility also in γ-Zn4Sb3 under electrical current.

During single-crystal-to-single-crystal (SCSC) phase transitions, a polymorph of a compound can transform to a more stable form while remaining in the solid state. By understanding the mechanism of these transitions, strategies can be developed to control this phenomenon. This is particularly important in the pharmaceutical industry, but also relevant for other industries such as the food and agrochemical industries. Although extensive literature exists on SCSC phase transitions in inorganic crystals, it is unclear whether their classications and mechanisms translate to molecular crystals, with weaker interactions and more steric hindrance. A comparitive study of SCSC phase transitions in aliphatic linear-chain amino acid crystals, both racemates and quasi-racemates, is presented. A total of 34 transitions are considered and most are classified according to their structural change during the transition. Transitions without torsional changes show very different characteristics, such as transition temperature, enthalpy and free energy, compared with transitions that involve torsional changes. These differences can be rationalized using classical nucleation theory and in terms of a difference in mechanism; torsional changes occur in a molecule-by-molecule fashion, whereas transitions without torsional changes involve cooperative motion with multiple molecules at the same time.

Small-angle neutron scattering (SANS) was recently applied to the in situ and operando study of the charge/discharge process in Li-ion battery full-cells based on a pouch cell design. Here, this work is continued in a half-cell with a graphite electrode cycled versus a metallic lithium counter electrode, in a study conducted on the SANS-1 instrument of the neutron source FRM II at the Heinz Maier-Leibnitz Zentrum in Garching, Germany. It is confirmed that the SANS integrated intensity signal varies as a function of graphite lithiation, and this variation can be explained by changes in the squared difference in scattering length density between graphite and the electrolyte. The scattering contrast change upon graphite lithiation/delithiation calculated from a multi-phase neutron scattering model is in good agreement with the experimentally measured values. Due to the finite coherence length, the observed SANS contrast, which mostly stems from scattering between the (lithiated) graphite and the electrolyte phase, contains local information on the mesoscopic scale, which allows the development of lithiated phases in the graphite to be followed. The shape of the SANS signal curve can be explained by a core–shell model with step-wise (de)lithiation from the surface. Here, for the first time, X-ray diffraction, SANS and theory are combined to give a full picture of graphite lithiation in a half-cell. The goal of this contribution is to confirm the correlation between the integrated SANS data obtained during operando measurements of an Li-ion half-cell and the electrochemical processes of lithiation/delithiation in micro-scaled graphite particles. For a deeper understanding of this correlation, modelling and experimental data for SANS and results from X-ray diffraction were taken into account.

Polyubiquitin chains linked via lysine (K) 63 play an important role in endocytosis and membrane trafficking. Their primary source is the ubiquitin protein ligase (E3) Rsp5/NEDD4, which acts as a key regulator of membrane protein sorting. The heterodimeric ubiquitin-conjugating enzyme (E2), Ubc13-Mms2, catalyses K63-specific polyubiquitylation in genome maintenance and inflammatory signalling. In budding yeast, the only ubiquitin protein ligase (E3) known to cooperate with Ubc13-Mms2 so far is a nuclear RING finger protein, Rad5, involved in the replication of damaged DNA. We now report a contribution of Ubc13-Mms2 to the sorting of membrane proteins to the yeast vacuole via the multivesicular body (MVB) pathway. In this context, Ubc13-Mms2 cooperates with Pib1, a FYVE-RING finger protein associated with internal membranes. Moreover, we identified a family of membrane-associated FYVE-(type)-RING finger proteins as cognate E3s for Ubc13-Mms2 in several species, and genetic analysis indicates that the contribution of Ubc13-Mms2 to membrane trafficking in budding yeast goes beyond its cooperation with Pib1. Thus, our results widely implicate Ubc13-Mms2 as an Rsp5-independent source of K63-linked polyubiquitin chains in the regulation of membrane protein sorting.

To enhance the vitality and overall operation of the nations patent system, federal officials should take decisive steps to increase the systems flexibility, openness, and reliability, says a new report from the National Academies National Research Council.

While every mode of transportation in the U.S. will be affected as the climate changes, potentially the greatest impact on transportation systems will be flooding of roads, railways, transit systems, and airport runways in coastal areas because of rising sea levels and surges brought on by more intense storms, says a new report from the National Research Council.

Over the last 25 years, deep-water oil and gas production in the Gulf of Mexico has increased significantly.

To transform the offshore oil and gas industry’s safety culture, operators, contractors, subcontractors, associations representing these groups, and federal regulators should collaborate to foster safety throughout all levels of the industry and confront challenges collectively, says a new report from the National Academies of Sciences, Engineering, and Medicine.

The U.S. Department of the Interior’s Bureau of Safety and Environmental Enforcement has ordered the National Academies of Sciences, Engineering, and Medicine to suspend all work on a study to review and update the bureau’s offshore oil and gas operations inspection program to enhance safety.

As a novel coronavirus spreads throughout the world and the number of cases and deaths continues to rise, almost no country or community remains untouched by this rapidly evolving threat.

Plácido Domingo has been hospitalized because of COVID-19-related complications, according to multiple reports.

He is in stable condition in an Acapulco, Mexico, hospital and will receive medical attention for "as long as the doctors find it necessary until a hoped-for full recovery," a spokesperson for Domingo told Opera News over the weekend.

Domingo's reported hospitalization comes just days after he posted a March 22 message on Facebook revealing that he had tested positive for the disease caused by the coronavirus.

"I feel it is my moral duty to announce that I tested positive for COVID19, also known as the Corona Virus. My family and I are and will remain individually isolated for as long as it is medically necessary. Today we all enjoyed good health, but I presented symptoms of coughing and fever, so I decided to take the test and the result was positive," Domingo said.

Domingo has been one of opera's most reliable and bankable stars and is known for his ability to sing tenor and baritone and in multiple languages, including Italian, English, Russian and Spanish.

Recently, the 79-year-old has been embroiled in controversy as several women accused the Spanish-born singer of sexual misconduct.

On March 10, NPR reported that LA Opera, which Domingo helped establish, announced that its investigation substantiated 10 "inappropriate conduct" claims levied against him dating back to as early as 1986. Domingo resigned as the LA Opera's general director in October.

Prior to that, he withdrew from a production of the Metropolitan Opera's performance of "Macbeth" amid allegations of sexual misconduct.

He has denied the allegations.

Domingo is among a growing list of celebrities who have announced they have tested positive for the coronavirus, including actor Tom Hanks and his wife Rita Wilson, actor Idris Elba, NBA star Kevin Durant, talk show host Andy Cohen and British Prime Minister Boris Johnson.

The L.A. Philharmonic will be the new operator of the John Anson Ford Theatre, the smaller outdoor venue near  the 101 Freeway across from the Hollywood Bowl, under a plan approved by the Los Angeles County Board of Supervisors.  

L.A.  funding sustains the Ford, and the county recently spent $80 million renovating the 1,200  seat amphitheater.  But attendance has been lackluster — and Supervisor Sheila Kuehl hopes the L.A. Philharmonic can change that. 

“The Ford will be able to take advantage of the natural synergies in marketing, capacity-building and program resources that simply haven’t been available to the Ford as an independent institution," she  said.

The move by the L.A. County  blindsided many local artists.  They say the Ford is an important incubator for diverse talent.  They also worry ticket prices will increase.  Prompted by their criticism, the Supervisors will require the Phil to meet with artists and annually review the diversity of the Ford’s shows with county officials.

Apple's latest mobile operating system — iOS 8 — is now available, and with it, a new technical hurdle for law enforcement. The company says it will be technologically impossible to access data on phones and iPads running iOS 8, because it won't allow user passcodes to be bypassed.

Our phones, of course, contain troves of information — contacts, messages, recordings — which can be helpful for investigative or prosecutorial purposes. The Supreme Court earlier this year ruled law enforcement cannot access that kind of data without a warrant. Prosecutors had already feared the warrant hurdle would be too much — Rockland County, N.Y., District Attorney Thomas Zugibe told the Wall Street Journal in June that technology "is making it easier and easier for criminals to do their trade," while the court "is making it harder for law enforcement to do theirs."

Now, even with a warrant, data from Apple devices running iOS 8 will be tough — and, Apple says, impossible — for law enforcement to get its hands on.

As The Washington Post reports, the move "amounts to an engineering solution to a legal quandary: Rather than comply with binding court orders, Apple has reworked its latest encryption in a way that prevents the company — or anyone but the device's owner — from gaining access to the vast troves of user data typically stored on smartphones or tablet computers."

Not so fast, writes an iOS forensics expert, Jonathan Zdziarski. Just because Apple will no longer help police doesn't mean police can't find ways to use existing commercial forensics tools to extract the data themselves. Wired Magazine describes how Zdziarski proved his own point:

Zdziarski confirmed with his own forensics software that he was still able to pull from a device running iOS 8 practically all of its third-party application data — that means sensitive content from Twitter, Facebook, Instagram, web browsers, and more — as well as photos and video. The attack he used impersonates a trusted computer to which a user has previously connected the phone; it takes advantage of the same mechanisms that allow users to siphon data off a device with programs like iTunes and iPhoto without entering the gadget's passcode.

"I can do it. I'm sure the guys in suits in the governments can do it," says Zdziarski.

And, Apple will still be able to turn over user data stored outside its phones, for example, on its iCloud service, The Washington Post notes. Users often back up photos, videos, emails and more to iCloud, as the recent nude photo theft reminded us.

Apple, in creating plausible deniability for itself, is also using its strongly worded new privacy stance as a marketing opportunity. It's reinforcing what it says is a commitment to privacy and transparency when it comes to government data requests. Apple says so far this year, it has received fewer than 250 government requests for data, including requests to unlock encrypted iPhones.
