SpaceX's newest Starship prototype has fired its engine for the first time, potentially paving the way for a test flight in the very near future. Space.com reports: The SN4, the latest test version of SpaceX's Mars-colonizing Starship vehicle, aced a "static fire" Tuesday night (May 5), lighting up its single Raptor engine briefly while remaining on the ground at the company's South Texas facilities. "Starship SN4 passed static fire," SpaceX founder and CEO Elon Musk said via Twitter late on Tuesday. [You can see video of the static fire here.] With the static fire in the rearview mirror, SpaceX can begin prepping the SN4 for its next big moment: an uncrewed test flight, which Musk has said will take the vehicle to a target altitude of about 500 feet (150 meters).

The CRISPR/Cas9 nucleases have been widely applied for genome editing in various organisms. Cas9 nucleases complexed with a guide RNA (Cas9–gRNA) find their targets by scanning and interrogating the genomic DNA for sequences complementary to the gRNA. Recognition of the DNA target sequence requires a short protospacer adjacent motif (PAM) located outside this sequence. Given that the efficiency of target location may depend on the strength of interactions that promote target recognition, here we sought to compare affinities of different Cas9 nucleases for their cognate PAM sequences. To this end, we measured affinities of Cas9 nucleases from Streptococcus pyogenes, Staphylococcus aureus, and Francisella novicida complexed with guide RNAs (gRNAs) (SpCas9–gRNA, SaCas9–gRNA, and FnCas9–gRNA, respectively) and of three engineered SpCas9–gRNA variants with altered PAM specificities for short, PAM-containing DNA probes. We used a “beacon” assay that measures the relative affinities of DNA probes by determining their ability to competitively affect the rate of Cas9–gRNA binding to fluorescently labeled target DNA derivatives called “Cas9 beacons.” We observed significant differences in the affinities for cognate PAM sequences among the studied Cas9 enzymes. The relative affinities of SpCas9–gRNA and its engineered variants for canonical and suboptimal PAMs correlated with previous findings on the efficiency of these PAM sequences in genome editing. These findings suggest that high affinity of a Cas9 nuclease for its cognate PAM promotes higher genome-editing efficiency.

Entrepreneur Ricky Chan’s information technology company has been hard at work developing a virtual reality application that enables designers and their clients to walk through different versions of their home or office without having to physically move a single piece of furniture.

From the colour of the walls to the style of fixtures and fittings, Mr Chan’s app caters to all personal tastes and design ideas.

“We have customers who are interior designers or furniture retailers. Our virtual reality application brings their sketches to life. Designers in the past needed weeks to produce sketches. Now they can make designs instantly,” he explained.

Up to 40% of the application was developed at Smart-Space 8 in Tsuen Wan, Cyberport’s first co-working space outside its main Pok Fu Lam campus.

“Cyberport provides funding that helps to lower our expenses and we can hold seminars here with a rental fee that is much lower than the market price,” Mr Chan added.
 

The 20,000 sq ft space launched last year was specifically designed with young entrepreneurs in mind and provides workshops and seminars for startups. For companies that wish to join the Smart-Space 8 community, one of its founders must be aged between 18 and 35 and the company itself should not have been in operation for longer than seven years.

Smart-Space 8 users are entitled to comprehensive entrepreneurial support and value-added services to accelerate their businesses such as the Cyberport Creative Micro Fund and Cyberport Incubation Programme.

Mr Chan, who lives in the New Territories, said the added bonus of setting up shop in Smart-Space 8 is the commute, as Cyberport in Pok Fu Lam is farther away for him and his clients.

Cyberport may be expanding beyond Pok Fu Lam, but some entrepreneurs like agriculture technology company CEO and founder Gordon Tam have opted to stay at the home campus because of the incentives available.

“The business network here is unique. There are so many startups and we encourage and learn from each other.”

Mr Tam’s company sells vegetables from an indoor farm to local supermarkets and is now exploring the overseas market. He credits the vibrant community and ecosystem at Cyberport for building up his business.

“Traditional agriculture comes with a host of problems and the efficiency of Hong Kong’s agriculture industry is relatively low. This is why we are looking into indoor agriculture. We want to grow plants in industrial buildings.”

When Mr Tam joined the Cyberport Incubation Programme, his firm was offered two years of rent reduction. But more importantly, he said, the space is a one-of-a-kind ecosystem where his team can brainstorm ideas and continue to innovate.

Other startup owners share the same sentiment. Information technology company CEO and founder Stark Chan noted that with Cyberport as a public body, it offers a lot of support and rents are more stable.

“We have been here since we first started up. My colleagues are familiar with this environment and the atmosphere is good for innovation,” Mr Chan said.
