Drop-on-demand deposition of water onto a −35 °C platform rapidly transforms water into ice. The dimension and geometry of the structures are critically controlled by droplet ejection frequency modulation and stage motions. The freeform approach obviates layer-by-layer construction and support structures, even for overhang geometries. Complex and overhang geometries, branched hierarchical structures with smooth transitions, circular cross-sections, smooth surfaces, and micro-scale features (as small as 50 µm) are demonstrated. As a sample application, the ice templates are used as sacrificial geometries to produce resin parts with well-defined internal features. This approach could bring exciting opportunities for microfluidics, biomedical devices, soft electronics, and art. * 2022-07-28 - [Scripps Research scientists discover new “origins of life” chemical reactions Scripps Research](https://www.scripps.edu/news-and-events/press-room/2022/20220728-krishnamurthy-origins-of-life-chemical-reactions.html) - "scientists ... have discovered a new set of chemical reactions that use cyanide, ammonia and carbon dioxide—all thought to be common on the early earth—to generate amino acids and nucleic acids, the building blocks of proteins and DNA." * 2022-08-02 - [Tuberculosis vaccine candidate VPM1002 safe in HIV- and non-HIV-exposed newborns as study shows Max-Planck-Gesellschaft](https://www.mpg.de/19040549/0801-bich-tuberculosis-vaccine-candidate-vpm1002-safe-in-hiv-and-non-hiv-exposed-newborns-as-study-shows-17216463-x) - "No other infectious disease has killed more people than tuberculosis.

Further, we observed activation of proregenerative genes in monocyte and macrophage cell populations, which may enhance tissue regeneration, neovascularization and dermal recovery." * 2023-01-24 - [Canadian team discovers power-draining flaw in most laptop and phone batteries CBC News](https://www.cbc.ca/news/canada/nova-scotia/battery-power-laptop-phone-research-dalhousie-university-1.6724175) - If you use polyethylene terephthalate (PET) tape in batteries and electronics it will cause ions to flow, so use polypropylene (PP) tape instead and it will not, giving you more battery life and not draining batteries. * 2023-03-30 - [Sounds emitted by plants under stress are airborne and informative: Cell](https://www.cell.com/cell/fulltext/S0092-8674(23)00262-3) * 2023-10-06 - [These bubbles kill cancer - Michigan Engineering News](https://news.engin.umich.edu/2023/10/these-bubbles-kill-cancer/) - Ultrasound breakthrough breaks up cancer and helps teach your immune system to recognize cancer.

It’s also called stereotactic radiosurgery. Even though it’s called surgery, a Gamma Knife procedure doesn't use incisions. It also isn’t a knife. Gamma Knife uses very precise beams of gamma rays to treat an area of disease (lesion) or growth (tumor). It’s most often used in the brain. The beams of gamma radiation send a very intense dose of radiation to a small area without a need to make an incision. Radiosurgery destroys cells so that they can’t grow. A lesion or tumor will shrink in size over time."

By default, the 'Max Usage' might be set to a high percentage, often consuming significant disk space. Follow these steps to reduce the 'Max Usage' setting: 1. **Open System Properties:** Press the "Windows Key", type "System Protection", and press Enter. This action opens the System Properties dialog box directly in the System Protection tab. 2. **Configure System Protection:** In the System Properties dialog, under the **System Protection** tab, locate the **OS (C:) (System)** entry, and click on the **Configure** button. This step will open the configuration settings for system protection. 3. **Adjust Disk Space Usage:** In the configuration settings, find the **Disk Space Usage** section. Here, you will see a slider under **Max Usage**. Adjust this slider to reduce the percentage of disk space allocated. It's typically recommended to set this to around 10%. 4. **Apply the Changes:** After adjusting the slider, click **Apply** to save the changes. > **Note:** Reducing the disk space allocated for system protection might limit the number of restore points that Windows can keep. Ensure that you have a backup of your important data before making these changes.
