Yplasma zaps the air to cool chips for data centers
David Garcia gave TechCrunch a demo video demonstration of a device developed by his company, Yplasma. A row of five candles sit in front of a harmonica-like device with wires hanging off it. Suddenly, the flames flicker and then snuff out.
Inside the device, two strips of copper coursing with electrical current are generating plasmas, or clouds of charged particles, that induce airflow through the cavity and out over the candles.
It's nothing a fan couldn't do, but Yplasma's actuator has no moving parts, and the strips are thin and flexible.
'It's cheap to manufacture, is very thin, so it fits everywhere, and also consumes very little energy,' Garcia told TechCrunch.
A small fan in a laptop might use 3 to 4 watts, Garcia said, but Yplasma's actuator would only use 1 watt to cool the same amount. Plus, its flexible form factor means it's easier to fit in increasingly space-constrained consumer electronics.
Those qualities have caught the attention of a major semiconductor manufacturer, he said.
To refine its actuators, Yplasma recently raised a $2.5 million seed round led by Faber with participation from SOSV, the company exclusively told TechCrunch. As part of the deal, Yplasma will run its research and development out of SOSV's Hax lab space in Newark, New Jersey, and offices in Madrid. The company was spun out of Spain's space agency, INTA.
The ability to manipulate air using nothing but electrical forces has a wide range of applications. Based on Yplasma's website, that could include vehicle aerodynamics, satellite propulsion, aircraft deicing, water harvesting, and more.
In fact, the startup's initial target market was wind turbines. There, being able to control airflow and reduce drag can boost the amount of electricity one generates by 10% to 15%, Garcia said. Plus, the plasma actuators can also be configured to generate heat, helping to de-ice turbine blades.
'In North America and other parts of the world, ice is a problem. For wind turbines, 20% of the energy is lost because of that,' he said.
Yplasma is still working on a product for wind turbines, and it's going to deploy a test at Sandia National Laboratory this summer. But Garcia said that after a project with the semiconductor manufacturer proved successful, Yplasma started devoting more attention to chip cooling.
The company is closely studying the data center market, too. Cooling is one of the biggest non-compute expenses in a data center, so improving the effectiveness and efficiency would help bolster the bottom line.
'There's nothing between fans and liquid cooling or immersive cooling, and immersive and liquid cooling is super expensive,' Garcia said. 'They're hungry for cooling solutions.'

Real Betis: Nobel Mendy's transfer to Rangers falls through
The deal between Betis and Rangers collapsed despite advanced talks. Nobel Mendy / Real Betis Nobel Mendy will not be joining Rangers after all. The Senegalese defender's transfer from Real Betis has collapsed following the results of his medical examination. Both clubs had already agreed on a financial package worth €3 million. The 21-year-old defender seemed set for a future in Scotland after several days of intensive negotiations between Real Betis and Rangers. The Andalusian and Scottish club officials had reached a financial compromise, including a 20% sell-on clause in favor of the Seville side. What went wrong? As planned, Nobel Mendy underwent his medical in Barcelona on August 13 before heading to Glasgow. But, unexpectedly, the transfer process came to a halt after this check-up. According to several sources, it was the medical examination results that convinced Rangers to pull the plug. The Ibrox management decided to abandon the negotiations after reviewing the outcome of the player's physical tests. This surprise decision now casts doubt on the Senegalese defender's immediate future, as he remains in Seville. Manuel Pellegrini had already excluded Nobel Mendy from his plans for the upcoming season. The Chilean coach had left the defender out of pre-season preparations and recent team training sessions, confirming Real Betis' intention to part ways with the former Paris FC player. What next for the Senegalese international? To be continued…

Dramatic Footage Captures Human Embryo Implanting In Real Time
In the mood for an action film? Try the one starring a human embryo implanting. It just dropped, and it's gripping. Scientists at the Institute for Bioengineering of Catalonia in Barcelona have recorded footage of a key stage of human development in real time, and in 3D, for the first time. In doing so, they witnessed a surprisingly invasive event. 'We have observed that human embryos burrow into the uterus, exerting considerable force during the process,' Samuel Ojosnegros, principal investigator of the IBEC's Bioengineering for Reproductive Health group, said in a statement. 'These forces are necessary because the embryos must be able to invade the uterine tissue, becoming completely integrated with it.' Ojosnegros is leader of a study published Friday in the journal Science Advances exploring how embryos overcome the maternal-tissue barrier. In their quest to implant, embryos release enzymes that break down the surrounding tissue. But while much implantation research focuses on the biochemical aspects of this complex and mysterious natural phenomenon, the IBEC team chose instead to examine the biomechanics. Embryo, Meet Lab-Grown Womb To investigate, they constructed an artificial uterine lining from a gel composed of collagen — a rigid protein abundant in fibrous uterine tissue — and other proteins needed for the embryo to develop. They then put dozens of human embryos left over from infertility treatments into the lab-made tissue matrix and used advanced high-resolution microscopy to capture them in action over time. Neither the matrix nor the embryo is naturally fluorescent, so the researchers had to rely on special techniques to visualize both. (The first half of the video below shows the process of cell compaction in the embryo. The second part shows the embryo invading the artificial uterine lining.) Past studies have observed tissue deformations that suggest cells apply force — when migrating and invading tumors, for example — and Ojosnegros and his team wanted to explore the hypothesis that this also happens in implantation. 'When we started placing embryos on fibrous matrixes, we noticed strong deformations in the material,' Ojosnegros said in an interview. 'That immediately suggested that mechanics play a crucial role in implantation, so we decided to explore this dimension more deeply.' Indeed, the footage of the cluster of cells meeting the uterus looks like a mini cosmic explosion. Many women experience abdominal pain and mild bleeding during implantation. 'We observe that the embryo pulls on the uterine matrix, moving and reorganizing it,' Amélie Godeau, a researcher in the Ojosnegros group and co-author of the study, said in a statement. 'It also reacts to external force cues. We hypothesize that contractions occurring in vivo may influence embryo implantation.' Barcelona's Dexeus University Hospital, home to a large women's health clinic, donated the embryos used in the study — all donor couples gave their signed informed consent and received information on the research project. Ayelet Lesman's biomedical engineering lab at Tel Aviv University quantified the force of the embryos on the faux womb. Eyes On Infertility Treatment The team hopes their research could lead to breakthroughs in infertility treatment, as failed implantation is a leading cause. 'Nobody really knows how frequent implantation failure occurs because we have no way of diagnosing it,' Dr. Norbert Gleicher, an infertility specialist with New York's Center for Human Reproduction, said in an interview. 'This diagnosis, therefore, can only be assumed, and such assumptions are reached if an infertile woman had 'X' number of good quality embryos transferred in IVF without pregnancy and no evidence of any other cause of infertility.' Gleciher was not part of the team that conducted the study. The researchers studied both mouse and human implantation to compare the mechanical differences. While the mouse embryo adheres to the uterine surface and then folds around it, essentially enveloping it, the human embryo is far more invasive. It completely penetrates the uterus and grows from the inside out by forming specialized tissues that connect to the mother's blood vessels. An 'Important First Observation' A number of reproductive scientists unaffiliated with the research out of IBEC have expressed excitement about it. Gleicher calls the new imagery an 'important first observation,' but stresses that it only represents one piece of the complex equation that determines whether an implantation will succeed. 'Implantation is not simply a mechanical process,' he said. 'It is a mechanical process, but at least in my opinion, it is first and foremost an immunological process' — one that determines whether the mother will tolerate the embryo or reject it. Still, the new footage sheds further light on a primordial burst hidden deep within the body, one we owe our very existence to.

A New Question For CIOs - Technology Sovereignty?
Reflecting back on a high-level meeting with few colleagues in Spain last month – and recent conversations with technology leaders globally – one theme that has risen quickly on many board agendas is technology sovereignty. It is an emerging and challenging risk that directly affects global applications and cloud infrastructure, and its significance is growing rapidly in the new world order. Left unaddressed, it poses direct consequences for business continuity — threatening not only IT operations, but also financial performance, regulatory compliance, and customer trust. With rising and unpredictable geopolitical tensions around the world, policy changes in a jurisdiction could limit or even halt cross-border cloud data flows. If that were to occur, global corporations with in-country operations tied into centralized infrastructure could face immediate operational disruption. This is a low-probability, but high-impact risk - one that warrants inclusion in strategic thinking around resilience and business continuity and should be on board agendas. The 'to-do' list for technology leaders was already daunting. The deck is already full and dominated by the pace of AI-driven innovation and the need to place substantial, and sometimes uncomfortable, bets on emerging technology. Equally, macroeconomic uncertainty and shifting trade policies are forcing a careful re-balancing – between driving cost optimization through global standardization – and building agility through more distributed infrastructure. Now, an additional layer of complexity has surfaced. Policy changes linked to geopolitical events could render parts of today's global application and infrastructure landscape unusable — overnight. Developing true alternatives quickly is extraordinarily difficult. Indeed, the technology market today offers few short-term answers, and establishing viable sovereign options or credible contingency plans requires both time and significant investment. This reality pushes CIOs and their corporate boards toward a fundamental reassessment of technology models, enterprise architectures, and cloud strategies. A pragmatic way forward is a framework across three lenses: - Risk Assessment & Exposure — map critical workloads and data dependencies that hinge on cross-border flows, identifying potential points of failure. - Strategic Options — diversify providers and regions, strengthen hybrid capabilities, and ensure data portability to reduce lock-in. - Governance & Partnerships — establish contingency playbooks, engage early with policy and regulatory bodies, and explore alliances with sovereign technology providers. Hard to do today, challenging to execute — and yet, a risk that cannot be ignored. This is on the agenda for one of our upcoming board meetings at the Executive Technology Board – as we tap into the collective intelligence of a curated group of Global CIO/CTO/CDO/CAIOs. Appreciate your perspectives on this.
