Biologists Uncover Previously Unknown Structure Hiding Inside Human Cells

gizmodo.com Natalia Mesa 2025-08-22 23:00:57

Even after decades of peering into cells, biologists are still finding surprises. In a twist, researchers at the University of Virginia and the National Institutes of Health uncovered a new organelle, dubbed the hemifusome. This tiny membrane-bound structure serves as a cellular recycling center and may hold the key to treating several genetic diseases. The research has been published in Nature Communications. “This is like discovering a new recycling center inside the cell,” co-author Seham E

Cell Towers Can Double as Cheap Radar Systems for Ports and Harbors (2014)

How do you see ships without a pricey radar system? The question has troubled seaports around the world as they work to improve security. Without radar installations, it can be hard for port employees to detect small ships like those employed by pirates or by the terrorists who attacked the USS Cole in 2000. A team of researchers in Germany can now offer security teams a new option, though: putting existing cellular towers to work as quick and dirty radar systems. Developed at the Fraunhofer In

Notorious Fungus Blamed for ‘Mummy’s Curse’ Is Now a Promising Cancer Treatment

gizmodo.com Margherita Bassi 2025-08-22 16:00:30

In the 1920s, a number of workers on the excavation team that uncovered King Tutankhamun’s tomb met untimely deaths. Five decades later, 10 out of 12 scientists died after entering the tomb of the 15th-century Polish King Casimir IV. In both cases, researchers suggested that fungal spores could have played a role in the mysterious deaths, specifically identifying the fungus Aspergillus flavus within the Polish burial. A. flavus is now making a comeback, but not as a reawakened killer from ancie

Android phones could soon warn you of “Stingrays” snooping on your communications

arstechnica.com Unknown 2025-08-23 07:00:50

Smartphones contain a treasure trove of personal data, which makes them a worthwhile target for hackers. However, law enforcement is not above snooping on cell phones, and their tactics are usually much harder to detect. Cell site simulators, often called Stingrays, can trick your phone into revealing private communications, but a change in Android 16 could allow phones to detect this spying. Law enforcement organizations have massively expanded the use of Stingray devices because almost every

After years of grand promises about how robotaxis would change the way we buy and use our cars, Tesla finally launched its taxi service. In one small portion of one city. With only a few cars and a few riders. Plus safety monitors in the passenger seat. Caution is a good thing in this industry, but what does all this say about where Tesla’s self-driving efforts really stand?

Raleigh One e-bike launches with VanMoof DNA

The Raleigh One e-bike is now official after The Verge first published details of it last week. It was developed for the Accell Group’s Raleigh brand with help from VanMoof’s cofounders, Ties and Taco Carlier, according to my sources. The announcement never mentions their involvement, which could be viewed as good or bad — good if you view the brothers as innovators, bad if you got burned during the VanMoof bankruptcy or the turmoil that preceded it.

Battery manufacturer Powin files for bankruptcy months after landing $200M loan

Battery manufacturer Powin filed for bankruptcy on Wednesday. The Oregon-based company said it has more than $300 million in debt. The Chapter 11 filing will let the company continue operating while it restructures its debt. Powin manufactured grid-scale batteries using lithium-iron-phosphate (LFP) cells from China. The company had been searching for alternative domestic suppliers, but the supply chain wasn’t sufficiently mature, Jeff Waters, the company’s former CEO, told Bloomberg in April.
