Global IT investments are expected to increase by 8% in 2024 compared to 2023 and amount to $5.06 trillion.
About it says in the latest forecast of the American research and consulting company Gartner, which specializes in IT markets.
The consulting company noted that «classic» enterprises still lag far behind IT companies in terms of spending.
To give AI-focused women academics and others their well-deserved — and overdue — time in the spotlight, TechCrunch has been publishing a series of interviews focused on remarkable women who’ve contributed to the AI revolution. We’re publishing these pieces throughout the year as the AI boom continues, highlighting key work that often goes unrecognized. Read more profiles here.
In the spotlight today: Anna Korhonen is a professor of natural language processing (NLP) at the University of Cambridge. She’s also a senior research fellow at Churchill College, a fellow at the Association for Computational Linguistics, and a fellow at the European Laboratory for Learning and Intelligent Systems.
Korhonen previously served as a fellow at the Alan Turing Institute and she has a PhD in computer science and master’s degrees in both computer science and linguistics. She researches NLP and how to develop, adapt and apply computational techniques to meet the needs of AI. She has a particular interest in responsible and “human-centric” NLP that — in her own words — “draws on the understanding of human cognitive, social and creative intelligence.”
A couple of solar-sector manufacturers have a powerhouse agreement that reaches a unique benchmark. Thanks to a $400 million, three-year deal between Heliene and Suniva, solar panels and cells will be entirely made in the U.S., a unique combination until now.
Electrek reports that to this point, solar cells — the contraption that turns sunlight into electricity — were imported.
Dr. Charles Buhler and Exodus Technologies claims that systems with electrostatic pressure differences or electrostatic divergent fields gives systems with a center of mass with non-zero force component (aka generate movement). Buhler is NASA’s subject matter expert on electrostatics. They want to move to demo the system in orbit. These kinds of claims are controversial but the work seems to be thorough. It will only cost about $500k to $1M to create a rideshare mission into orbit to test the system. The mass of an early orbital system would greatly exceed the active materials of the propulsion, which would reduce performance. High performance space propulsion would need to increase the active materials as a percentage of the mass of the craft.
Dr. Charles Buhler discusses an experimental propulsion results based on asymmetrical electrostatic pressure, in a device described in International Patent# WO2020159603A2. The device is described as a system and method for generating a force from a voltage difference applied across at least one electrically conductive surface. The applied voltage difference creates an electric field resulting in an electrostatic pressure force acting on at least one surface of an object. Asymmetries in the resulting electrostatic pressure force vectors result in a net resulting electrostatic pressure force acting on the object. The magnitude of the net resulting electrostatic pressure force is a function of the geometry of the electrically conductive surfaces, the applied voltage, and the dielectric constant of any material present in the gap between electrodes.
Dr. Buhler has experience working with electrostatic discharge & ESD safety for the Space Shuttle Program, the International Space Station Program and the Hubble Space Telescope Program. He was also a Co-Investigator for three NASA Research Announcements funded by the Mars Exploration Program, and is currently working on NASA’s Dust Project focused on utilizing electrostatic methods to remove dust from personnel and equipment that will be sent to the Moon through NASA’s Constellation Program.

A significant space weather event has prompted the National Oceanic and Atmospheric Administration (NOAA) to issue a Geomagnetic Storm Alert.
The Space Weather Message Code ALTK07, issued at 1952 UTC on April 19, 2024, indicates that the geomagnetic K-index has reached a value of 7, crossing the threshold at 1951 UTC during the synoptic period of 1800–2100 UTC.
Initially, space experts anticipated the storm’s intensity to fluctuate between a G1 and G2 level, potentially escalating to G3 by Sunday.
Actin is a highly abundant protein that controls the shape and movement of all our cells. Actin achieves this by assembling into filaments, one actin molecule at a time. The proteins of the formin family are pivotal partners in this process: positioned at the filament end, formins recruit new actin subunits and stay associated with the end by ‘stepping’ with the growing filament.
There are as many as 15 different formins in our cells that drive actin filament growth at different speeds and for different purposes. Yet, the exact mechanism of action of formins and the basis for their different inherent speeds have remained elusive. Now, for the first time, researchers from the groups of Stefan Raunser and Peter Bieling at the Max Planck Institute of Molecular Physiology in Dortmund have visualized at the molecular level how formins bind to the ends of actin filaments.
This allowed them to uncover how formins mediate the addition of new actin molecules to a growing filament. Furthermore, they elucidated the reasons for the different speeds at which the different formins promote this process. The MPI researchers used a combination of biochemical strategies and electron cryo-microscopy (cryo-EM). The breakthrough, published in the journal Science, can help us explain why certain mutations in formins can lead to neurological, immune, and cardiovascular diseases.
