Sherpa, a startup from Bilbao, Spain that was an early mover in building a voice-based digital assistant and predictive search for Spanish-speaking audiences, has raised some more funding to double down on a newer focus for the startup: building out privacy-first AI services for enterprise customers.

The company has closed $8.5 million, funding that Xabi Uribe-Etxebarria, Sherpa’s founder and CEO, said it will be using to continue building out a privacy-focused machine learning platform based on a federated learning model alongside its existing conversational AI and search services. Early users of the service have included the Spanish public health services, which were using the platform to analyse information about COVID-19 cases to predict demand and capacity in emergency rooms around the country.

The funding is coming from Marcelo Gigliani, a managing partner at Apax Digital; Alex Cruz, the chairman of British Airways; and Spanish investment firms Mundi Ventures and Ekarpen. The funding is an extension to the $15 million Sherpa has already raised in a Series A. From what I understand, Sherpa is currently also raising a larger Series B.

The world’s first remote tattoo was completed by a 5G-powered robotic arm fitted with a tiny needle.

Tattoo artist Wes Thomas drew the design on a mannequin arm while a robot in another location copied his motions on Dutch actress Stijn Fransen’s wrist.

The final result is a ‘minimalist’ design that honors Fransen’s love out the outdoors that has been dubbed the ‘Impossible Tattoo.’

Starship SN11 will re-attempt a Static Fire test Tuesday – following a scrub on Monday – ahead of a potential flight later this week. Forever subject to change due to numerous considerations – ranging from weather, hardware parameters, and paperwork approval – SN11 will mark the final test of this iteration of Starship before the program moves into the next phase of testing.

Following SN11’s flight, SpaceX will move on to SN15, 16, and 17, alongside testing with Super Heavy prototypes BN1 and BN2, before shooting for an orbital launch with SN20 and BN3. In typical SpaceX-style, that orbital launch has an astonishing – and unlikely – “by July 1” target. At the very least, this target portrays SpaceX’s Starship drive to push the vehicle into operation. SN11:

Might interest some, mentions telomeres.

~~~

Aging is a common factor in many diseases. So, what if it were possible to treat them by acting on the causes of aging or, more specifically, by acting on the shortening of telomeres, the structures that protect chromosomes? This strategy is being pursued by the Telomeres and Telomerase Group of the Spanish National Cancer Research Centre (CNIO), which has already succeeded in curing pulmonary fibrosis and infarctions in mice by lengthening telomeres. Now they take a first step towards doing the same with renal fibrosis by demonstrating that short telomeres are at the origin of this disease, which is also associated with aging.

The new study will be published this week in the journal Nature Aging.

The interplanetary interloper won’t come closer than 1.25 million miles to Earth, but it will present a valuable scientific opportunity for astronomers.

The largest asteroid predicted to pass by our planet in 2021 will be at its closest on March 21, providing astronomers a rare opportunity to get a good look at a rocky relic that formed at the dawn of our solar system.

Called 2001 FO32, the near-Earth asteroid will make its closest approach at a distance of about 1.25 million miles (2 million kilometers) – or 5 1/4 times the distance from Earth to the Moon. There is no threat of a collision with our planet now or for centuries to come.

Energy efficient light-emitting diodes (LEDs) have been used in our everyday life for many decades. But the quest for better LEDs, offering both lower costs and brighter colors, has recently drawn scientists to a material called perovskite. A recent joint-research project co-led by the scientist from City University of Hong Kong (CityU) has now developed a 2-D perovskite material for the most efficient LEDs.

From household lighting to mobile phone displays, from pinpoint lighting needed for endoscopy procedures, to light source to grow vegetables in Space, LEDs are everywhere. Yet current high-quality LEDs still need to be processed at high temperatures and using elaborated deposition technologies—which makes their production cost expensive.

Scientists have recently realized that —semiconductor materials with the same structure as calcium titanate mineral, but with another elemental composition—are extremely promising candidate for next generation LEDs. These perovskites can be processed into LEDs from solution at room temperature, thus largely reducing their production cost. Yet the electro-luminescence performance of perovskites in LEDs still has a room for improvements.
