Scientists engineer a bacteria to produce a drug used to treat Parkinson’s disease

The results of the study could lead to new treatment options. In a groundbreaking new study published in the journal Nature on Thursday, researchers have compared the brain cells of patients who had died from either Parkinson’s disease or dementia to people unaffected by the disorders and found which brain cells are responsible for both conditions.


A team of researchers has created a bacteria that can produce a steady and consistent source of medicine inside a patient’s gut, suggesting the possibility for genetically edited bacteria to be an efficient Parkinson’s disease treatment.

Moreover, the researchers have shown via preclinical experiments that the novel treatment technique is not only safe and well-tolerated, but it also reduces side effects that can occur when other treatments are utilized.

An engineered probiotic

For long, scientists have been experimenting with ways of engineering bacteria to fit our needs for decades. The new research is the latest example of that.

High school students design a bottle that turns seawater into drinking water

Mangrove trees inspire thermal and membrane-based desalination system.


Four US students, taking part in a program aimed at high school girls interested in engineering, have designed a desalinating water bottle. The currently hypothetical device would be compact and portable so could offer increased accessibility over existing desalinating designs that mimic transpiration.

Laurel Hudson, Gracie Cornish, Kathleen Troy and Maia Vollen met at Virginia Tech’s C-Tech2 program where they were given an assignment to ‘reinvent the wheel’. Choosing to focus on the global water crisis and inspired by drinking straws used by hikers to purify water, they considered if it was possible to make a bottle that produced drinking water from seawater. They reached out to Jonathan Boreyko, an associate professor in the department of mechanical engineering, who was researching synthetic trees at the time. He agreed to help, and, during the height of the Covid-19 pandemic, the group met virtually at night to discuss their research. Along with Ndidi Eyegheleme, a graduate student in Boreyko’s lab, they planned and produced a model to evaluate the inner workings of their design.

Chip startups using light instead of wires gaining speed and investments

April 26 (Reuters) — Computers using light rather than electric currents for processing, only years ago seen as research projects, are gaining traction and startups that have solved the engineering challenge of using photons in chips are getting big funding.

In the latest example, Ayar Labs, a startup developing this technology called silicon photonics, said on Tuesday it had raised $130 million from investors including chip giant Nvidia Corp (NVDA.O).

While the transistor-based silicon chip has increased computing power exponentially over past decades as transistors have reached the width of several atoms, shrinking them further is challenging. Not only is it hard to make something so miniscule, but as they get smaller, signals can bleed between them.

Elon Musk’s SpaceX could probe Uranus on NASA’s flagship mission

Could SpaceX be heading to Uranus next? The National Academies of Sciences, Engineering, and Medicine seems to think it should. The organization has released its latest decadal survey of planetary science and astrobiology. According to a report by Teslarati published on Wednesday, the survey hints that NASA should undertake a flagship mission to Uranus on SpaceX’s Falcon Heavy rocket.

The Uranus Orbiter and Probe

The mission is not entirely new. Called the Uranus Orbiter and Probe (UOP), the proposal has been under work for several years by a team that includes scientists from NASA, the University of California, and Johns Hopkins University. Now, with SpaceX’s Falcon Heavy rocket, the researchers feel they have the technology to make their long-held dream a reality.

Capturing Solar Energy and Converting It to Electricity When Needed — Up to 18 Years Later

The researchers behind an energy system that makes it possible to capture solar energy, store it for up to eighteen years, and release it when and where it is needed have now taken the system a step further. After previously demonstrating how the energy can be extracted as heat, they have now succeeded in getting the system to produce electricity, by connecting it to a thermoelectric generator. Eventually, the research – developed at Chalmers University of Technology 0, Sweden – could lead to self-charging electronic gadgets that use stored solar energy on demand.

“This is a radically new way of generating electricity from solar energy. It means that we can use solar energy to produce electricity regardless of weather, time of day, season, or geographical location. It is a closed system that can operate without causing carbon dioxide emissions,” says research leader Kasper Moth-Poulsen, Professor at the Department of Chemistry and Chemical Engineering at Chalmers.

The Hydrogen Stream: Fuel cell engines for stationary power uses

Countries, especially potential exporters, should improve hydrogen statistics to justify and promote investments in hydrogen. The measures should result from broad cooperation, also intended to standardize and homogenize measurements, said Columbia University‘s Anne-Sophie Corbeau. “Countries could start working together to determine how best to collect hydrogen data, both on the demand and production sides, and include existing consumption as well as potential future consumption in new sectors. Statistics on the demand side need to anticipate new uses in buildings, industry, transport, and power, as well as account for hydrogen’s potential use to produce other energy products such as ammonia and methanol,” the French scholar wrote on Monday.

Vancouver-based First Hydrogen has identified four industrial sites in the United Kingdom and is advancing discussions with landowners to secure land rights to develop green hydrogen production projects. It said it would be working with engineering consultants Ove Arup & Partners Limited (ARUP) for engineering studies and designs. “The sites are all in prime industrial areas spread strategically across the North and South of the United Kingdom and will each accommodate both a large refueling station — for light, medium and heavy commercial vehicles with on-site hydrogen production, to serve the urban areas of Greater Liverpool, Greater Manchester, the London area, and the Thames Estuary — and a larger hydrogen production site of between 20 and 40 MW, for a total for the four sites of between 80 MW and 160 MW,” First Hydrogen wrote on Monday. The Canadian company wants to use the production facilities to serve customers of its automotive division. “First Hydrogen’s green hydrogen van is to begin demonstrator testing in June with final delivery for road use in September 2022.”

New York State is getting 38 MW of community bifacial solar farms

Ranging from 4.5 megawatts (MW) to 7.5 MW in size, the six solar farms are currently in late stages of construction in central New York State, and some are already mechanically completed. All six projects are scheduled to be operational in the second quarter of 2022.
