Moon develops targeted, reliable, long-lasting kill switch

Tae Seok Moon, associate professor of energy, environmental and chemical engineering at the McKelvey School of Engineering at Washington University in St. Louis, has taken a big step forward in his quest to design a modular, genetically engineered kill switch that integrates into any genetically engineered microbe, causing it to self-destruct under certain defined conditions.

His research was published Feb. 3 in the journal Nature Communications.

Hypoint opens UK hydrogen cell development unit to power eVTOL and other aircraft

Silicon Valley hydrogen fuel cell innovator Hypoint has inaugurated a new UK unit intended to speed development of its air-cooled aviation power technology, and ready it to supply zero-carbon power to next-generation aircraft like electric takeoff and landing vehicles (eVTOL) as they prepare to launch services.

HyPoint’s tech uses compressed air for both cooling and oxygen supplies delivered to its fuel systems, which are lighter, less polluting, have longer lifespans, and enable seven times more flight capacity than lithium-ion and other chemical batteries. Those attributes are luring developers of existing, new drone, and eVTOL craft to give emerging hydrogen cell products serious consideration as drivers of their vehicles – especially as the world seeks to reduce its carbon output. In 2018, aviation sector’s share of global CO2 emissions was 2.5%.

Inspired by insects, engineers create spiky materials that could pop bacteria

Researchers have created intricately patterned materials that mimic antimicrobial, adhesive and drag reducing properties found in natural surfaces.

The team from Imperial College London found inspiration in the wavy and spiky surfaces found in insects, including on cicada and dragonfly wings, which ward off .

They hope the new could be used to create self-disinfecting surfaces and offer an alternative to chemically functionalized surfaces and cleaners, which can promote the growth of antibiotic-resistant bacteria.

New set of chemical building blocks makes complex 3D molecules in a snap

A new set of molecular building blocks aims to make complex chemistry as simple and accessible as a toy construction kit.

Researchers at the University of Illinois Urbana-Champaign and collaborators at Revolution Medicines Inc. developed a new class of chemical building blocks that simply snap together to form 3D with complex twists and turns, and an automated machine to assemble the blocks like a 3D printer for molecules.

This automation could allow chemists and nonchemists alike to develop new pharmaceuticals, materials, diagnostic probes, catalysts, perfumes, sweeteners and more, said study leader Dr. Martin D. Burke, a professor of chemistry at Illinois and a member of the Carle Illinois College of Medicine, as well as a medical doctor. The researchers reported their findings in the journal Nature.

Keren Haruvi — President, Sandoz US, Head Of North America — Global Generic Medicine Access For All

Pioneering global generic medicine access to improve and extend people’s lives — keren haruvi snir-president, sandoz US, head of north america.

Keren Haruvi is President of Sandoz US and Head of their North America business (https://www.novartis.us/about-us/our-leadership/us-country-l…n-haruvi).

Sandoz is a division of the Novartis Group and a global leader in generic pharmaceuticals and biosimilars and was established in 2003, when Novartis united all of its generics businesses under the name Sandoz – a single global brand with a long history. Since then, Sandoz has grown into a leading global generics business with annual sales of approximately US$10 billion.

In her current role, Keren leads Sandoz’ largest commercial and country organization – the United States – which is responsible for over 35% of Sandoz global revenue. She also oversees Sandoz commercial operations in Canada. In addition to serving on the Novartis Country Leadership Team, Keren is a member of the Global Sandoz Executive Committee.

Prior to joining Sandoz, Keren served as Global Head of M&A at Novartis International AG. Her early career began at Teva Pharmaceutical Industries where she steadily advanced in leadership roles to Senior VP, Global Business Development and Alliance Management.

University of Delaware researchers’ carbon capture advance could bring environmentally friendly fuel cells closer to market.

University of Delaware engineers have demonstrated a way to effectively capture 99% of carbon dioxide from air using a novel electrochemical system powered by hydrogen.

MIT Engineers Create the “Impossible” — New Material That Is Stronger Than Steel and As Light as Plastic

The new substance is the result of a feat thought to be impossible: polymerizing a material in two dimensions.

Using a novel polymerization process, MIT chemical engineers have created a new material that is stronger than steel and as light as plastic, and can be easily manufactured in large quantities.

The new material is a two-dimensional polymer that self-assembles into sheets, unlike all other polymers, which form one-dimensional, spaghetti-like chains. Until now, scientists had believed it was impossible to induce polymers to form 2D sheets.

Researchers report game-changing technology to remove 99% of carbon dioxide from air

University of Delaware (UD) engineers have demonstrated a way to effectively capture 99% of carbon dioxide from air using a novel electrochemical syst.

For the first time, it is possible to see the quantum world from multiple points of view at once. This hints at something very strange – that reality only takes shape when we interact with each other.

Scientists use ‘sticky’ DNA to build organized structures of gel blocks

Researchers from the Okinawa Institute of Science and Technology Graduate University (OIST) have used microscopic strands of DNA to guide the assembly of gel blocks that are visible to the naked eye.

The blocks, which measure up to 2mm in length and contain DNA on their surface, self-assembled in around 10–15 minutes when mixed in a solution, the scientists reported today in the Journal of the American Chemical Society.

“These hydrogel blocks are, we believe, the largest objects so far that have been programmed by DNA to form organized structures,” said Dr. Vyankat Sontakke, first author of the study and a postdoctoral researcher in the OIST Nucleic Acid Chemistry and Engineering Unit.
