Reports and Proceedings
Scientists from around the world will present more than 500 abstracts in obesity science and medicine and related topics at the 39th Annual Meeting of The Obesity Society (TOS) at ObesityWeek® 2021. This online event will take place Nov. 1–5, 2021 at www.obesityweek.org. On-Demand materials and other elements of the interactive conference will remain available online through Dec. 31, 2021.
While attempting to save the northern white rhinoceros from extinction through advanced assisted reproduction technologies, the scientists and conservationists of the BioRescue consortium place the highest value on respecting the life and welfare of the individual animals involved. In a special, in-depth ethical risk assessment, the team has reached the decision to retire the older of the two remaining females, 32-year-old Najin, as a donor of egg cells (oocytes). This leaves the ambitious programme with one female that can provide oocytes, Najin’s daughter Fatu. Weighing up risks and opportunities for the individuals and the entire species rendered this decision without an alternative. This situation will further strengthen the need for stem cell associated techniques, which are also part of the BioRescue mission as well as long-term biobanking. Najin will remain an important part of the mission as an ambassador for her kind and by transferring social knowledge to future offspring.
A team of researchers has created a software system designed to model epidemics, with the aim of maximizing public-health protections while minimizing economic and social costs.

Drugs that promise to help people lose weight have had a checkered past, such as the infamous fen-phen that was pulled from the market in 1997 after reports of heart valve damage. But now, drug company pipelines are filling up with new molecules that aim to help people safely shed extra pounds, according to a cover story in Chemical & Engineering News, an independent news outlet of the American Chemical Society.

Targeting the dentate nucleus with deep brain stimulation (DBS) was safe and feasible for promoting post-stroke rehabilitation in a first-in-human study at Cleveland Clinic. Treatment response in the phase I EDEN trial of dentate nucleus DBS for upper extremity hemiparesis from stroke was encouraging, enabling the procedure to advance to a phase II randomized controlled trial to evaluate safety and efficacy, reported principal investigators Andre Machado, M.D., Ph.D., and Kenneth Baker, Ph.D., in a late-breaking abstract presentation at the annual meeting of the Congress of Neurological Surgeons (CNS) on Oct. 20.
Biowaste, food waste and other natural biodegradable refuse make up a third of French household waste. This biodegradable waste is a potential source of energy for producing electricity and heat but can also provide a wealth of products with high added value for farmers. While all households are expected to be able to sort biowaste* at the source by late 2023, the European multidisciplinary project DECISIVE has focused on developing micro-scale anaerobic digestion (AD) in urban areas. Coordinated by INRAE, this programme, launched in 2016 with 14 partners** in France, Germany, Spain, Italy, Belgium and Denmark, has led to full-scale testing of efficient micro-AD units at local level, capable of producing both energy for local use and a biopesticide for farms. From an environmental and socio-economic standpoint, the results of the project, which will draw to a close in late October 2021, brings the prospect of a concrete roll-out of a circular system within reach.
Europeans want urgent action on climate change but remain committed meat-eaters and question policy proposals such as banning the sale of new petrol vehicles after 2030, according to a new poll from the YouGov-Cambridge Centre for Public Opinion Research that surveyed environmental attitudes in seven European countries, including the UK.
Presented at the Optica (formerly OSA) 2021 Frontiers in Optics + Laser Science (FiO LS) meeting (01 - 04 November) researchers from Boston University, USA, will report the development of frequency translating add/drop filters based on electro-optically modulated photonic molecules. The new class of filters could open important new avenues for on-chip light manipulation.

The blockage of lung arteries by a blood clot results in pulmonary embolism – a condition requiring emergency care that affects more than 300,000 people in the United States each year. Existing treatments, however, may not fully remove the clot, necessitating the development of new therapeutic strategies for pulmonary embolism. Now, in a major step forward, researchers at the Lewis Katz School of Medicine at Temple University developed a device known as the Bashir™ Endovascular Catheter (Thrombolex, Inc.), which effectively dissolves the clots in the lungs, with no major bleeding risk. Bleeding following clot dissolution is a significant risk for thrombolytic therapies currently on the market. The evidence comes from the prespecified interim analysis of the National Institutes of Health (NIH)-sponsored RESCUE trial, a clinical study designed to assess the efficacy and safety of the Bashir™ Endovascular Catheter for the treatment of acute pulmonary embolism.
CO2 emissions from buildings and construction fell in 2020 due to the economic impacts of COVID-19 but a lack of real transformation in the sector means emissions will keep rising, contributing to dangerous climate change, according to the UN's 2021 Global Status Report for Buildings and Construction.
