Not long ago, Formlabs launched a new ESD Resin specifically for applications that need to keep parts safe from electrostatic discharge (ESD). Now, the double unicorn has announced the latest member of its selective laser sintering (SLS) range of materials—the new high-performance Nylon 12 GF Powder. Good for 3D printing engineering and manufacturing functional prototypes and end-use parts that require thermal stability and structural rigidity, the newly launched material offers excellent stiffness and is the latest meant for use with the Formlabs Fuse 1 industrial SLS 3D printer, which was released last year.

Formlabs’ Nylon 12 GF powder makes it possible to 3D print parts that are thermally stable, and can maintain their dimensional accuracy under load. In the past, glass-filled Nylon materials have been used for a variety of applications, such as 3D printing a scale model, a prosthetic drum stick, a bike rack, loudspeakers, and even a bar! This particular material—one of many Formlabs is planning to introduce for its industrial Fuse 1 3D printer—is said to be a good choice for printing threads and sockets, strong jigs and fixtures, parts subjected to high temperatures and sustained loading, functional prototypes for compsite parts, and replacement parts.

One of the especially promising therapies to appear in the realm of anti-aging research involves a set of molecules known as Yamanaka factors, which scientists have deployed to rejuvenate aging cells, trigger muscle regeneration and tackle glaucoma. New research at the Salk Institute has sought to build on these short-term and specific use cases by demonstrating how these molecules can reverse signs of aging in middle-aged and elderly mice, with no evidence of health problems following the extended treatment.

The Yamanaka factors at the center of this study are a set of four reprogramming molecules that can reset the molecular clock found in the cells of the body. They do so by returning unique patterns of chemicals known as epigenetic markers, which evolve through aging, to their original states.

Circa 2020

The short-term prospects for wind and solar power look rocky amid the economic upheaval of the coronavirus. But long term, renewables could emerge stronger than ever, especially if governments integrate support for clean energy into Covid-19 economic-recovery programs.

Hydrogen sulphide (H2S) is a colourless gas with the odour of rotten eggs and has recently been recognized as a signal mediator in physiological activities related with the regulation of homeostasis, the vascular system and the inflammatory system. Here we show that H2S donors, including sodium hydrogen sulphide (NaHS), GYY 4137 and diallyltrisulfide (DATS), synergistically enhanced the anti-cancer effect of a green tea polyphenol (−)-epigallocatechin-3-O-gallate (EGCG) against multiple myeloma cells without affecting normal cells. NaHS significantly potentiated the anti-cancer effect of EGCG and prolonged survival in a mouse xenograft model. In this mechanism, H2S enhanced apoptotic cell death through cyclic guanosine monophosphate (cGMP)/acid sphingomyelinase pathway induced by EGCG.

The XPrize and other competitions are helping to advance science and technological innovation.

Over the years, we have had alumni go on to become successful academic scientists, company managers and entrepreneurs. The networks that the participants create with each other during the competition are useful to tap into throughout their careers. Recently, I also learnt that a winning team from 2020 decided to create a bioelectronics start-up, INIA Biosciences, that aims to use ultrasound to interact with the immune system to relieve chronic inflammatory diseases.

More companies and foundations are seeing the advantages of science competitions and are organizing innovation challenges. The organizers benefit from recruiting talented people, gaining fresh ideas and promoting an image of innovativeness. The participants are rewarded with training, network building and prize money. In addition to the Innovation Cup, we also organize events such as the €1 million Future Insight Prize, which is given out annually to honour and enable scientists solving key challenges of humanity.

A scientist opens a laptop in front of a patient. On screen, a boy, tied to a fleet of balloons, fades in. As he rises into the air, the scene cuts abruptly to an office, where a man sits in front of his boss. A question then appears: “Was anyone in the video wearing a tie?”

Jie Zheng, a postdoctoral fellow at Boston Children’s Hospital, had flown to Los Angeles to show the video to this patient, who has a severe seizure disorder. Like with the 18 other patients who were part of the study, neurosurgeons had placed electrodes in the patient’s brain to pinpoint what had been causing their seizures. Zheng and a group of scientists in a federally funded BRAIN Initiative consortium used this opportune moment to find neurons involved in the creation of memories. While subjects watched clips from movies and answered questions that tested their memory of the videos, the electrical activity of their brains was monitored.

Over three years, the work — a collaboration between researchers at Cedars-Sinai in L.A., Boston Children’s, and the University of Toronto — led to the discovery of two new groups of brain cells: boundary and event cells. The researchers theorized that these neurons are involved in cleaving experiences into distinct events that humans can better remember. The study, published in Nature Neuroscience, may pave the way for new treatments for memory disorders, the authors said.

One group of mice received regular doses of the Yamanaka factors from the time they were 15 months old until 22 months, approximately equivalent to age 50 through 70 in humans. Another group was treated from 12 through 22 months, approximately age 35 to 70 in humans. And a third group was treated for just one month at age 25 months, similar to age 80 in humans.

LA JOLLA—(March 7, 2022) Age may be just a number, but it’s a number that often carries unwanted side effects, from brittle bones and weaker muscles to increased risks of cardiovascular disease and cancer. Now, scientists at the Salk Institute, in collaboration with Genentech, a member of the Roche group, have shown that they can safely and effectively reverse the aging process in middle-aged and elderly mice by partially resetting their cells to more youthful states.

“We are elated that we can use this approach across the life span to slow down aging in normal animals. The technique is both safe and effective in mice,” says Juan Carlos Izpisua Belmonte, co-corresponding author and a professor in Salk’s Gene Expression Laboratory. “In addition to tackling age-related diseases, this approach may provide the biomedical community with a new tool to restore tissue and organismal health by improving cell function and resilience in different disease situations, such as neurodegenerative diseases.”
