Transformer model, a deep learning framework, has achieved state-of-the-art results across diverse domains, including natural language, conversation, images, and even music. The core block of any Transformer architecture is the attention module, which computes similarity scores for all pairs of positions in an input sequence. Since it requires quadratic computation time and quadratic memory size of the storing matrix, with the increase in the input sequence’s length, its efficiency decreases.

Thus, for long-range attention, one of the most common methods is sparse attention. It reduces the complexity by computing selective similarity scores from the sequence, based on various methods. There are still certain limitations like unavailability of efficient sparse-matrix multiplication operations on all accelerators, lack of theoretical guarantees, insufficiency to address the full range of problems, etc.

TESS, the Transiting Exoplanet Survey Satellite, was launched in 2018 with the goal of discovering small planets around the Sun’s nearest neighbors, stars bright enough to allow for follow-up characterizations of their planets’ masses and atmospheres. TESS has so far discovered seventeen small planets around eleven nearby stars that are M dwarfs — stars that are smaller than the Sun (less than about 60% of the Sun’s mass) and cooler (surface temperatures less than about 3900 kelvin). In a series of three papers that appeared together this month, astronomers report that one of these planets, TOI-700d, is Earth-sized and also located in its star’s habitable zone; they also discuss its possible climate.

CfA astronomers Joseph Rodriguez, Laura Kreidberg, Karen Collins, Samuel Quinn, Dave Latham, Ryan Cloutier, Jennifer Winters, Jason Eastman, and David Charbonneau were on the teams that studied TOI-700d, one of three small planets orbiting one M dwarf star (its mass is 0.415 solar masses) located one hundred and two light-years from Earth. The TESS data analysis found the tentative sizes of the planets as being approximately Earth-sized, 1.04, 2.65 and 1.14 Earth-radii, respectively, and their orbital periods as 9.98, 16.05, and 37.42 days, respectively.

DOLE, France (Reuters) — Growing global demand for food is putting a squeeze on available land and one French startup says it has the answer: indoor insect farming.

Ynsect raised $224 million from investors including Hollywood star Robert Downey Jr.’s Footprint Coalition this month to build a second insect farm in Amiens in northern France.

The company breeds mealworms that produce proteins for livestock, pet food and fertilisers, and will use the funds to build what it says will be the world’s largest insect farm.

“In a breakthrough study published on February 19th in Nature Biomedical Engineering, researchers connected neural dust implants reduced to 1.7 cubic millimeters to rat sciatic nerves. The implanted device, called the StimDust system, consisted of very few components, which will be scaled down for future applications. A piezoceramic ultrasonic transducer generated power allowing for wireless communication and stimulation. A capacitor stored any excess energy generated from ultrasonic beams. Bipolar stimulating electrodes directly interfaced with the nerve while a cuff attached to a small circuit-board allowed the device to adhere physically to the nerve. These components were sufficient to generate or record nerve-impulses. In anesthetized rodents, they elicited muscular contractions with the StimDust system.”

While Neuralink, Elon Musk’s startup-venture focused on creating a brain-computer interface, garners lots of coverage in the biotechnology space, other bioelectronics ventures continue innovating in this space.

iota Biosciences, a spin-off company from UC Berkley formed in 2017, made news two years ago by securing $15 million in Series A funding and again last year announcing a partnership with Astellas Pharma Inc. Bolstered by studies in rodents, iota Biosciences advances towards their vision. In a press release on their partnership, founders Jose Carmena and Michel Maharbiz commented:

Following the first-ever triple Raptor Static Fire test, Starship SN8 is pushing through the pre-launch milestones. The nosecone has since been installed – resulting in the first full Starship stack since MK1 – allowing for a second Static Fire test this coming week. The second Static Fire test will involve propellant being fed from the Header Tank system.

SN8 passed through the first major objective in impressive fashion, progressing in a staggered manner with a preburner attempt aborted, followed by a preburner test involving at least two of the Raptors.
