Northwestern University engineers have developed the smallest-ever remote-controlled walking robot -- and it comes in the form of a tiny, adorable peekytoe crab. From the report: Just a half-millimeter wide, the tiny crabs can bend, twist, crawl, walk, turn and even jump. The researchers also developed millimeter-sized robots resembling inchworms, crickets and beetles. Although the research is exploratory at this point, the researchers believe their technology might bring the field closer to realizing micro-sized robots that can perform practical tasks inside tightly confined spaces. Smaller than a flea, the crab is not powered by complex hardware, hydraulics or electricity. Instead, its power lies within the elastic resilience of its body. To construct the robot, the researchers used a shape-memory alloy material that transforms to its "remembered" shape when heated. In this case, the researchers used a scanned laser beam to rapidly heat the robot at different targeted locations across its body. A thin coating of glass elastically returns that corresponding part of structure to its deformed shape upon cooling. As the robot changes from one phase to another -- deformed to remembered shape and back again -- it creates locomotion. Not only does the laser remotely control the robot to activate it, the laser scanning direction also determines the robot's walking direction. Scanning from left to right, for example, causes the robot to move from right to left. The research was published in the journal Science Robotics.

Scientists from the University of Michigan have "fabricated a nanoparticle to deliver an inhibitor to brain tumor in mouse models, where the drug successfully turned on the immune system to eliminate the cancer," reports ScienceDaily. "The process also triggered immune memory so that a reintroduced tumor was eliminated -- a sign that this potential new approach could not only treat brain tumors but prevent or delay recurrences." From the report: The small molecule inhibitor AMD3100 was developed to block the action of CXCR12, a cytokine released by the glioma cells that builds up a shield around the immune system, preventing it from firing up against the invading tumor. Researchers showed in mouse models of glioma that AMD3100 prevented CXCR12 from binding with immune-suppressive myeloid cells. By disarming these cells, the immune system remains intact and can attack the tumor cells. But AMD3100 was having trouble getting to the tumor. The drug did not travel well through the bloodstream, and it did not pass the blood brain barrier, a key issue with getting drugs into the brain. The Castro-Lowenstein lab collaborated with Joerg Lahann, Ph.D., Wolfgang Pauli Collegiate Professor of Chemical Engineering at the U-M College of Engineering, to create protein-based nanoparticles to encapsulate the inhibitor, in the hopes of helping it pass through the bloodstream. Castro also connected with Anuska V. Andjelkovic, M.D., Ph.D., professor of pathology and research professor of neurosurgery at Michigan Medicine, whose research focuses on the blood brain barrier. They noted that glioma tumors create abnormal blood vessels, interfering with normal blood flow. The researchers injected AMD3100-loaded nanoparticles into mice with gliomas. The nanoparticles contained a peptide on the surface that binds to a protein found mostly on the brain tumor cells. As the nanoparticles traveled through the bloodstream toward the tumor, they released AMD3100, which restored the integrity of the blood vessels. The nanoparticles could then reach their target, where they released the drug, thus blocking the entry of the immune-suppressive myeloid cells into the tumor mass. This allowed the immune cells to kill the tumor and delay its progression. [...] Among the mice whose tumors were eliminated, the researchers then reintroduced the tumor, simulating a recurrence. Without any additional therapy, 60% of mice remained cancer-free. The research has been published in the journal ACS Nano.

An anonymous reader quotes a report from CNBC: Airbus is launching a U.K.-based facility focused on hydrogen technologies, a move which represents the firm's latest attempt to support the design of its next generation of aircraft. In a statement Wednesday, Airbus said the Zero Emission Development Centre in Filton, Bristol, had already begun working on the development of the tech. One of the site's main goals will center around work on what Airbus called a "cost-competitive cryogenic fuel system" that its ZEROe aircraft will need. Details of three zero-emission, "hybrid-hydrogen" concept planes under the ZEROe moniker were released back in Sept. 2020. Airbus has said it wants to develop "zero-emission commercial aircraft" by the year 2035. The ZEDC in the U.K. will join other similar sites in Spain, Germany and France. "All Airbus ZEDCs are expected to be fully operational and ready for ground testing with the first fully functional cryogenic hydrogen tank during 2023, and with flight testing starting in 2026," the company said.

RED filed a lawsuit yesterday suing (PDF) Nikon for infringing on its video compression patents. PetaPixel reports: The lawsuit was filed in a southern California federal court today and asserts that the Japanese camera manufacturer and its United States subsidiaries have illegally infringed on seven patents that deal specifically with "a video camera that can be configured to highly compress video data in a visually lossless manner." In the filing, RED notes a type of compression that it says it has patented and is in use by Nikon in the Z9: "The camera can be configured to transform blue and red image data in a manner that enhances the compressibility of the data. The data can then be compressed and stored in this form. This allows a user to reconstruct the red and blue data to obtain the original raw data for a modified version of the original raw data that is visually lossless when demosaiced. Additionally, the data can be processed so the green image elements are demosaiced first, and then the red and blue elements are reconstructed based on values of the demosaiced green image elements." This compression comes thanks to a partnership with intoPIX's TicoRAW which was announced last December. [...] The TicoRAW feature has been in the news for months, but RED was likely waiting for it to be implemented into a competitor's camera before filing a lawsuit. RED's lawsuit says Nikon's infringement on its patent was "willful" and claims Nikon would have known about RED's patents. [...] RED then cites multiple lawsuits it has filed against Kinefinity, Sony, and Nokia over the years. RED is seeking damages or royalties for the infringement as well as an injunction to ban Nikon from further infringing.

Substack stopped fundraising efforts for a round of $75 million to $100 million, the New York Times reported Thursday. Axios reports: The round could have valued the newsletter publication platform between $750 million and $1 billion. But the abandoned plans come amid the market's cooling and layoffs among other tech firms. NYT reported that Substack told investors its 2021 revenue was about $9 million. That means its potential valuation of $1 billion would have been 100x its revenue. Substack touted in November that it has more than 1 million paid subscriptions and that its top 10 writers collectively generate $20 million in annual revenue. But only a fraction of that contributes to Substack's bottom line.

"Quanta not patching vulnerable baseboard management controllers leaves data centers vulnerable," writes long-time Slashdot reader couchslug. "Pantsdown was disclosed in 2019..." Ars Technica reports: In January 2019, a researcher disclosed a devastating vulnerability in one of the most powerful and sensitive devices embedded into modern servers and workstations. With a severity rating of 9.8 out of 10, the vulnerability affected a wide range of baseboard management controllers (BMC) made by multiple manufacturers. These tiny computers soldered into the motherboard of servers allow cloud centers, and sometimes their customers, to streamline the remote management of vast fleets of computers. They enable administrators to remotely reinstall OSes, install and uninstall apps, and control just about every other aspect of the system -- even when it's turned off. Pantsdown, as the researcher dubbed the threat, allowed anyone who already had some access to the server an extraordinary opportunity. Exploiting the arbitrary read/write flaw, the hacker could become a super admin who persistently had the highest level of control for an entire data center. Over the next few months, multiple BMC vendors issued patches and advisories that told customers why patching the vulnerability was critical. Now, researchers from security firm Eclypsium reported a disturbing finding: for reasons that remain unanswered, a widely used BMC from data center solutions provider Quanta Cloud Technology, better known as QCT, remained unpatched against the vulnerability as recently as last month. As if QCT's inaction wasn't enough, the company's current posture also remains baffling. After Eclypsium privately reported its findings to QCT, the solutions company responded that it had finally fixed the vulnerability. But rather than publish an advisory and make a patch public -- as just about every company does when fixing a critical vulnerability -- it told Eclypsium it was providing updates privately on a customer-by-customer basis. As this post was about to go live, "CVE-2019-6260," the industry's designation to track the vulnerability, didn't appear on QCT's website. [...] "[T]hese types of attacks have remained possible on BMCs that were using firmware QCT provided as recently as last month," writes Ars' Dan Goodin in closing. "QCT's decision not to publish a patched version of its firmware or even an advisory, coupled with the radio silence with reporters asking legitimate questions, should be a red flag. Data centers or data center customers working with this company's BMCs should verify their firmware's integrity or contact QCT's support team for more information."

Broadcom has signaled its $61 billion acquisition of VMware will involve a "rapid transition from perpetual licenses to subscriptions." The Register reports: That's according to Tom Krause, president of the Broadcom Software Group, on Thursday's Broadcom earnings call. He was asked how the semiconductor giant plans to deliver on its guidance that VMware will add approximately $8.5 billion of pro forma EBITDA to Broadcom within three years of the deal closing -- significant growth given VMware currently produces about $4.7 billion. And subscriptions was the answer. Krause also repeatedly said Broadcom intends to invest in VMware's key product portfolio and is pleased to be acquiring a sales organization and channel relationships that give it reach Broadcom does not currently enjoy. [...] Krause and Broadcom CEO Hock Tan both said Broadcom plans to nurture VMware's 300,000-plus customer base. The move to subscription-based licensing will apparently happen over the course of the next few years. [...] VMware may also experience slower growth in the short term due to the licensing shift. Krause said Broadcom is willing to live with lower margins for VMware than it expects from CA and Symantec, with R&D to benefit as a result. The software boss pledged ongoing investment and innovation for VMware's core infrastructure products, naming vSphere, VSAN, vRealize and NSX as the subjects of ongoing love and attention
