Magnetic field responses in Drosophila

[ad_1]

arising from: M. Bassetto et al. Nature https://doi.org/10.1038/s41586-023-06397-7 (2023)

Bassetto et al.1 reported that Drosophila are unable to detect magnetic fields using a conditioning2 and negative geotaxis assay3, and on this basis, they dismiss these and all further experimental studies published on Drosophila magnetic fields4,5,6,7,8,9,10,11,12. Critically, fly magnetic geotactic responses were replicated independently by Bae et al.12, yet this important and extensive confirmatory study is not discussed. Furthermore, Bae et al. successfully demonstrated a magnetic field conditioning response12, underlining how experienced Drosophila groups can successfully negotiate magnetic paradigms. I have reanalysed the data from all three geotactic experiments from Bassetto et al.1 and, despite serious flaws in methodology, their results reveal that Drosophila detect magnetic fields.

In the geotaxis experiments of Fedele et al.3, the percentage of male flies climbing 15 cm in 15 s generated the maximum separation between sham responses to blue light (BL) and those to red light (RL), which provide the critical positive controls. Forty-eight per cent of CS-LE males exposed to BL reached this criterion, compared to 12% in RL (that is, about 36% absolute, 400% relative enhancement in BL; Fig. 1a). The contention of Bassetto et al.1 that flies should fall into either climber or non-climber categories and not reflect an underlying Gaussian distribution does not stand serious scrutiny. Bae et al.12 carried out similar experiments, comparing geotaxis at about 0 μT magnetic field in darkness (approximately equivalent to RL for flies) and white light (500 lx, including BL). They observe a geotactic difference of about 300% between the two lighting conditions expressed as positive geotaxis (non-climbers; Fig. 1b). Experiment 1 of Bassetto et al.1 replicates the procedure of Fedele et al.3 in equipment I provided, but apparently using mixed groups of males and females. It is of concern that geotactic responses are barely different between the sham BL and RL critical positive controls (Fig. 1a). I recalculated that the CS-LE strain reached 26% criterion under BL with 22% under RL, whereas corresponding values for the more active CS-OX were 52% (BL) and 45% (RL) (Fig. 1a). Given these tiny absolute and relative differences between RL and BL, compared to those in previous studies3,12, one questions how any magnetic field effect could be detected in such limited phenotypic space. Evidently, Bassetto et al.1 did not suspect a problem with these positive controls (see Supplementary Information for the probable reason). In addition, strain CS-LE is considerably less active in BL than in Fedele et al.3, possibly owing to inbreeding, as I originally provided a single vial of this line. Consequently, I predominantly limit my reanalyses to CS-OX, which is as active in BL as CS-LE is in Fedele et al.3 (Fig. 1a).

Raw data are shown for all experiments; horizontal black lines represent means. a, Reanalysis of Bassetto et al.1 raw data for positive control conditions. The plot shows a comparison of raw data for climbing response of CS-LE flies under sham to RL and BL (red and blue, respectively) conditions from Fedele et al.3 with raw data for CS-LE and CS-OX (experiment (Expt) 1) reanalysed from Bassetto et al.1. The y axis shows the percentage of flies that reached 15 cm in 15 s. Mean climbing scores averaged over 10 trials for each tube for the experiment of Fedele et al.3 (one-tailed t4 = 5.82, P = 0.002, based on 3 replications each for RL and BL; total observations, n = 60). Experiment 1 of Bassetto et al.1 has 300 observations under sham, divided equally between BL and RL, in which 60 tubes (each with 10 flies) are tested 5 times. The raw data and mean responses are shown for CS-LE and CS-OX. For ANOVA, the proportion of flies reaching criterion is calculated for each tube (strain: F1,117 = 17.07, P « 0.0001; light: F1,117 =9.82, P = 0.002; interaction: F = 1,117 0.09, not significant (NS); based on n = 121 average climbing scores from 5 trials (total flies, n = 601)). False discovery post hoc values are shown (see Supplementary Information). In experiment 3 of Bassetto et al.1, only 26/208 (12.5%) and 6/199 (3%) CS-LE trials produced flies that reached criterion in BL and RL, respectively, so 182 and 193 trials, respectively, had a score of 0. The mean percentage of five trials in which individual flies reached criterion and Mann–Whitney U-test result comparing BL to RL are shown. It is clear from the raw data that there is barely any overlap between RL and BL climbing scores in the positive controls of Fedele et al.3, whereas the overlap is considerable in the raw data for experiments of Bassetto et al.1. b, Results of the experiment of Bae et al.12 comparing climbing in darkness and white light at 0 μT.

In experiment 2, Bassetto et al.1 expose groups of 10 individuals to 0 μT, at which Earth’s magnetic field is neutralized, compared to 90-, 220- and 300-μT exposures with corresponding sham (ambient, about 40-μT) controls. They do not use 500-μT exposures as in Fedele et al.3. Inspecting the automated tracking for CS-OX revealed 1,062,956 frames logged from an expected 1,800,000 (accuracy 59%). Importantly, no positive controls were carried out involving RL versus BL for CS-OX. Nevertheless, taking their results at face value, the prediction3,12 is that flies should climb higher at 0 μT compared to magnetic field exposure. Reanalysis of their data reveals significantly higher climbing at 0 μT than at 90-, 220- and 300-μT exposures combined (Fig. 1c). Also predicted is that 0-μT-exposed flies should climb higher than corresponding shams, but the higher-intensity exposures should reduce climbing compared to sham, generating an interaction. Figure 1e reveals that at 90-, 220- and 300-μT exposures, climbing is reduced compared to corresponding shams, as expected (but not significantly), whereas there is little difference between 0 μT compared to its sham.

For Flyvac experiment 3, Bassetto et al.1 tracked individual flies. The accuracy of the tracking is 84.9%, considerably better than experiment 2. In CS-LE, 12.5% (26/208) of BL trials included flies that reached the climbing criterion (15 cm in 15 s in at least 1 of 5 trials), compared to 3% in RL (6/199). The mean percentage of flies across all trials reaching criteria was 4% for BL and 1% for RL, so this criterion cannot be used to investigate magnetic field effects (Fig. 1a). Nevertheless, I detected significant differences between the lighting conditions using Fisher exact (P = 0.004) and Mann–Whitney (P = 0.001) tests, reflecting absolute BL-to-RL enhancement of 9.5%, relative 415%. Consequently, I recalculated the mean height climbed at 15 s for CS-LE under sham in RL and BL, which was 6.17 cm to 8.75 cm (142% BL enhancement), considerably better than experiment 1. Yet again, positive RL and BL controls were not carried out for CS-OX, so I assumed that CS-OX discriminates BL and RL as well as CS-LE does. I therefore took the average height climbed for CS-OX individuals at 15 s and reanalysed the data. The prediction is that 0-μT-exposed flies should climb higher than those of the other exposures combined. The prediction is partially fulfilled, but unlike experiment 2, the difference is not significant (Fig. 1d). Flies exposed to 0 μT should also climb higher in BL than sham (about 40 μT), but at 300 μT, sham flies should climb higher than exposed flies. Two-way analysis of variance (ANOVA) reveals a significant interaction generated by the flies at 0 μT climbing higher than sham, with a strong reciprocal significant response at 300 μT (Fig. 1f), so the prediction is fulfilled. A similar result is obtained when I examined the percentage of CS-OX flies reaching criterion (15 cm in 15 s), noting how much higher CS-OX climb than CS-LE in BL (compare experiment 3 in Fig. 1a with Fig. 1g). One wonders what the result would have been had Bassetto et al.1 used an exposure of 500 μT (as in Fedele et al.3), as the magnetic field effect in this particular single-fly paradigm seems to gain momentum with increasing intensity. The over-elaborate and highly conservative ANOVA of Bassetto et al.1 (see Methods of ref. 1) produced non-significant results, after which the authors did not seem to interrogate their data further. Had they inspected carefully the relevant part of their own figures (see my Supplementary Fig. 1), they might have thought twice about their conclusions.

I have shown that the positive controls for experiment 1 worked poorly, if at all, and that in experiment 2, comparing 0-μT exposures to the higher exposures gave the expected result, despite poor tracking accuracy and no positive controls. In the more robust final experiment, despite no positive controls, the interaction expected, in which flies climb higher under 0 μT and lower under higher exposures compared to sham, also gave the predicted result. Instead of engaging in some relatively simple troubleshooting for each paradigm, increasing BL intensity in experiment 1 (and perhaps experiments 2 and 3), and tuning up the tracking software in experiment 2, Bassetto et al.1 preferred the option of simply racking up large (108,609) numbers. It is extraordinary that no positive RL or BL controls were carried out for CS-OX, because it has long been known that fly strains differ in their responses to RL13.

Finally, one wonders why Bassetto et al.1 dismissed all fly magnetic field experiments2,3,4,5,6,7,8,9,10,11,12 from eight independent groups using different paradigms. Bassetto et al.1 state that because flies do not use a navigational compass, they have no use of a magnetic sense. They ignore the demonstration of Bae at al.12 that flies use the Earth’s magnetic field to fly low. Drosophila melanogaster feed and oviposit on decaying fruits that lie mainly at ground level, so a magnetic sense would be adaptive for foraging. In turn, this suggests that magnetoreception is primary, and the functions it serves, foraging or navigation, lie downstream. Furthermore, magnetic field effects can be mediated in flies by the 52-residue cryptochrome (Cry) carboxyl terminus alone without the canonical FAD-binding site and the 3–4 Trp residues required to generate radical pairs in Cry, results obtained using adult circadian behaviour (under impeccably controlled conditions) and single-larval-motoneuron physiological assays8,10,11. Mouritsen, Hore and collaborators favour a model in which full-length avian CRY4 with FAD binding and Trp tetrads is required for detecting magnetic fields, based on in vitro spectroscopy experiments on CRY4 peptides circumstantially allied to behavioural evidence from bird navigation studies14. Clearly the two competing hypotheses, Cry C terminus versus full-length Cry, although not mutually exclusive, are at odds. The critically flawed attempt of Bassetto et al.1 to cast doubt on all fly magnetic field work, together with their statement that (genetically and molecularly inscrutable) night-migratory songbirds are the best organism for understanding the underlying mechanism of light-dependent magnetoreception (ignoring the molecularly tractable navigating monarch butterfly15), should be seen clearly in this context.

Nintendo Switch 2 will reportedly be larger than its predecessor and feature magnetic Joy-Con controllers

[ad_1]

Another day, another Nintendo Switch 2 rumor. This one, however, comes from a reliable source.

Spotted by Eurogamer, Spanish gaming publication Vandal reports that, according to various accessory manufacturers, that the Nintendo Switch 2 will feature Joy-Con controllers that magnetically connect to the console. If accurate, this would mean both the controllers and the Switch unit itself would undergo a significant change, eschewing the need for that rather awkward rail connection system.

Beautiful magnetic stand turns iPad into iMac

[ad_1]

Make your iPad into an iMac with Elago's beautiful magnetic stand
Your iPad can also be a stylish iMac mini with this stand.
Photo: Elago

The Elago Magnetic Stand for iPads lifts the tablet up and does so beautifully. It closely mimics the design of the iMac, making the iPad into a small desktop.

Most iPad stands offer a very limited selection of colors — perhaps only silver. Elago’s comes in a range of them, including pink.

Stand up and take notice

An iPad takes care of your email, web browsing and social networking needs. Why stop there? Add a keyboard and mouse/trackpad and it can be all the computer you need. But making a tablet into a desktop requires a good stand. Something like the Elago Magnetic Stand for iPads.

Attach the included magnetic ring to your tablet and the iPad will cling tightly to magnets in the stand. But the iPad also can be removed with a twist and a tug. Elago’s Magnetic Folio Case (available separately for $26.99) does not interfere with the magnetic connection.

A hinge allows the iPad to swivel to point toward the user, making it easy to see the screen whether you’re typing an email to your boss or watching a TikTok video.

As for the rest of the design, they say imitation is the sincerest form of flattery. If so, then Elago is sincerely flattering the design of the 24-inch iMac’s built-in stand. Combined with an iPad, some people are likely to wonder when Apple started selling an iMac mini.

Elago Magnetic Stand for iPads in sand pink

Apple’s all-in-one comes in an array of colors, and so does the Magnetic Stand. It’s available in light blue, dark gray, silver and sand pink. Not surprisingly, Elago offers the Magnetic Folio Case in these same colors.

So make your iPad into an iMac mini with the Elago Magnetic Stand. The cost is $110.99.

Making a Space Mouse magnetic controller from scratch

DIY Space Mouse magnetic controller 3D printing project

3D designers that use 3D modelling software might be interested in a unique project by Salim Benbouziyane during which a magnetic controller is created for use with Fusion 360 another CAD and modelling applications. Imagine the ease of sculpting digital models with the flick of a wrist, rotating and zooming with a finesse that feels like second nature.

For those who work with computer-aided design (CAD) software, such as Fusion 360, the ability to smoothly navigate 3D models is crucial. A new do-it-yourself (DIY) space mouse has emerged, offering an intuitive way to interact with digital designs. This innovative tool is inspired by professional-grade devices that provide complete freedom to view designs from any angle, a feature that is essential for detailed work.

At the heart of this DIY space mouse is a three-axis magnetometer, which essentially acts as a joystick. It detects magnetic fields, allowing the user to move through the digital space with precision. The magnetometer is part of a well-thought-out spring system that ensures accurate and responsive control. To keep the device steady during use, it has a weighted base filled with steel balls. The programming behind this gadget is intricate, as it involves filtering and calibrating the magnetometer’s readings. This process is what translates the physical movements into the commands that navigate the CAD software.

DIY Space Mouse magnetic controller

Creating a seamless integration between the space mouse and the CAD software was one of the project’s significant challenges. The solution was to develop custom shortcuts that could mimic mouse and keyboard actions within Fusion 360. After thorough testing of prototypes, a final version was produced. This version was encased in a 3D-printed enclosure that not only looks professional but also houses additional features such as LED lighting and shortcut buttons. These enhancements not only make the device more functional but also add to its aesthetic appeal.

Here are some other articles you may find of interest on the subject of 3D printing :

The space mouse is designed to be wireless, which means it can be used in various workspaces without the clutter of cables. Although it currently offers a high level of control, the developers are considering adding an Inertial Measurement Unit (IMU) in future models. This would provide the full six degrees of freedom that professional-grade space mice offer. The performance of the device will continue to be tested and refined. For those interested in building their own, the project files have been made available.

This custom space mouse is a shining example of what can be achieved when ingenuity meets technology. It demonstrates that with a bit of creativity, an understanding of complex concepts, and the use of readily available technology, the way we interact with CAD software can be transformed. This device is not just a tool; it’s a bridge between the physical and the digital, making the design process more fluid and natural.

Building a 10 Stage Coilgun magnetic force projectile launcher

Building a 10 Stage Coilgun magnetic force projectile launcher

Imagine being able to create a device that uses magnetic force to launch a projectile. The latest innovation from Electronoobs the creator of inspirational project tutorials for electronics hobbyists. Has introduced the second-generation of a previously made 10-stage coilgun, which now comes with an improved printed circuit board (PCB) and a custom-made enclosure produced by 3D printing. This new version is not only more efficient but also safer, representing a significant step forward for those who enjoy building and experimenting with their own electronic devices.

At the heart of the coilgun’s functionality is its PCB. The updated design brings all the stages together onto a single board, which makes the building process easier and reduces the chances of making mistakes. The PCB has been designed with sophisticated software to match the coilgun’s requirements perfectly, which ensures that it works as well as possible.

The enclosure for the coilgun, made using 3D printing technology, has two main purposes. It is designed to cover the high-voltage parts, protecting users from the risk of electric shock. The enclosure also strengthens the coilgun by protecting its complex internal components from damage, while also giving it a modern, professional look.

How to make a Coilgun

As you put the coilgun together, your skill in soldering will be put to the test. You’ll need to solder various parts, including coils, capacitors, and infrared LEDs. The PCB has been made with thick copper tracks, which can be challenging when it comes to managing heat. Being good at soldering is crucial for making connections that last and preventing the device from getting too hot.

The most thrilling part of the process is testing the coilgun. You’ll adjust the timing of each stage with the help of infrared sensors to make sure the firing power is as strong as it can be. Getting the calibration right is very important, as it ensures that the projectile travels at the highest possible speed when it hits a plywood target.

After testing, you’ll add features that make the coilgun easier to use, such as a segmented case for the power supply and a voltage indicator to help you keep track of the charge. To make the design even better, you might want to make the battery housing bigger and add a port for loading projectiles.

When you’re working on this project, it’s important to always think about safety because the coilgun works with high voltage. But building the device is more than just a fun activity; it’s a chance to learn more about advanced electronics. You’re encouraged to share what you learn and your experiences with the community, which helps create a space where everyone can work together and keep getting better.
