The Framework Laptop 16 is the most customizable laptop we’ve ever seen, with tons of input and port options, and the promise of upgradable graphics. It has a bright screen and solid battery life, but it’s expensive, and you could get something with more performance for the price.

Framework introduces replaceable graphics for the first time, along with customizable keyboards and other accessories.

How can clean drinking water be produced in the simplest most cost-effective way possible? This is what a recent study published in Nature Sustainability hopes to find out as an international team of researchers led by The University of Texas at Austin (UT Austin) have developed a novel method for producing clean drinking water using only a syringe and a hydrogel filter. This study holds the potential to develop cheaper and simpler methods for producing clean drinking water for individuals around the world.

“The pressing concern of particle-polluted water, particularly in remote and underdeveloped regions where people frequently rely on contaminated water sources for consumption, demands immediate attention and recognition,” said Dr. Guihua Yu, who is a professor of materials science in the Walker Department of Mechanical Engineering at UT Austin and a co-author on the study. “Our system, with its high efficiency in removing diverse types of particles, offers an attractive yet practical solution in improving freshwater availability.”

For the study, the researchers developed their water purification system that incorporates a biodegradable hydrogel filter capable of removing particles as small as approximately 10 nanometers (0.0000003937 inches) from water that is injected into the hydrogel using a syringe. Once injected, the water passes through the hydrogel and into any drinking or storage water apparatus. Along with filtering out particles at 10 nanometers, the researchers also noted the filter efficiency rate is 100 percent, both of which surpass commercially available filters. For context, the researchers note that commercial filter efficiency rates for particles larger than 10 nanometers are approximately 40 percent and 80 percent, respectively. Additionally, the device can be scaled at various sizes and is reusable, resulting in both reduced cost and environmental impact.

Lumiere, on its part, addresses this gap by using a Space-Time U-Net architecture that generates the entire temporal duration of the video at once, through a single pass in the model, leading to more realistic and coherent motion.

“By deploying both spatial and (importantly) temporal down-and up-sampling and leveraging a pre-trained text-to-image diffusion model, our model learns to directly generate a full-frame-rate, low-resolution video by processing it in multiple space-time scales,” the researchers noted in the paper.

A Japanese start-up is planning to test a ground-based fusion laser to combat the growing threat of space debris.

Docking and berthing are not just about connecting two spacecraft; they are vital for crew transfer, resupply missions, and the assembly and maintenance of the ISS.

As of December 22, 2023, the ISS hosted four spacecraft: the SpaceX Dragon Endurance crew spacecraft, the Soyuz MS-24 crew ship, and the Progress 85 and 86 resupply ships. In January, the Axiom-3 crew arrived in another Dragon spacecraft.

The future of space exploration relies on these intricate docking procedures, which will continue to evolve with new technologies and spacecraft.

Treating complex diseases such as skin cancer often requires simultaneous administration of multiple anticancer drugs. The delivery of such life-saving therapeutic drugs has evolved with the rise of nanotechnology-based drug carriers. Nanoplatforms offer numerous advantages, including increased bioavailability, lowered dosages, and improved biodistribution.

Now a team of researchers, led by Professor Myoung-Hwan Park from Sahmyook University in South Korea, has developed a light-responsive nanofiber-based novel drug delivery system (DDS) targeting skin cancer. The DDS was studied in a detailed manner, beginning with its synthesis and characterization to its biocompatibility, drug release profile, and efficacy against skin cancer. These research findings are published in the Journal of Drug Delivery Science and Technology.

Explaining the motivation behind the present research, Dr. Park states, “Conventional drugs can be efficiently delivered in a controlled manner through nano-engineered platforms, and such an approach increases the overall effectiveness of the treatment. This approach improves outcomes in cancer drug therapy by ensuring precise delivery at optimal dosages.”

Cryptocurrency is usually “mined” through the blockchain by asking a computer to perform a complicated mathematical problem in exchange for tokens of cryptocurrency. But in research appearing in the journal Chem a team of chemists has repurposed this process, asking computers to instead generate the largest network ever created of chemical reactions which may have given rise to prebiotic molecules on early Earth.

This work indicates that at least some primitive forms of metabolism might have emerged without the involvement of enzymes, and it shows the potential to use blockchain to solve problems outside the financial sector that would otherwise require the use of expensive, hard to access supercomputers.

“At this point we can say we exhaustively looked for every possible combination of chemical reactivity that scientists believe to had been operative on primitive Earth,” says senior author Bartosz A. Grzybowski of the Korea Institute for Basic Science and the Polish Academy of Sciences.

This is good info but I’d like to do it naturally. I wonder if healing my gut biome with pro and prebiotics can help. There’s been psychiatric side effects with ozempic in a few cases. There’s often some kind of side effect when not natural but some people could benefit if monitored by a doctor.

Popular weight-loss and diabetes drugs, such as Ozempic and Wegovy, target metabolic pathways that gut microbes and food molecules already play a key role in regulating.

“Our modeling suggests that shallow moonquakes capable of producing strong ground shaking in the south polar region are possible from slip events on existing faults or the formation of new thrust faults,” said Dr. Thomas R. Watters.

Objects expand and contract from heating and cooling, and planetary objects are no different, which includes our nearest celestial neighbor, our Moon. Billions of years ago, the Moon was very volcanically active which caused it to expand from all the internal heat driving the volcanic activity. However, as this internal heat died down, the Moon began to cool, and has been contracting, or shrinking, ever since. Now, a recent study published in The Planetary Science Journal discusses how this shrinkage could be responsible for the lunar south pole becoming warped, leading to landslides and moonquakes, which increases safety risks for future astronauts, specifically with NASA’s Artemis program.

For the study, the researchers developed models of how seismic waves from moonquakes could cause powerful ground shaking and landslides near the lunar south pole, which is home to de Gerlache scarp, with a scarp being a geologic feature formed from the Moon contracting. Data from the Apollo Passive Seismic Network, which were a series of seismometers left on the lunar surface during Apollo 11, 12, 14, 15, and 16 and functioned between 1969 and 1977, indicates that de Gerlache scarp could have formed from an approximate magnitude-5.3 moonquake. The reason de Gerlache scarp is a crucial location is due to its proximity to one of the potential landing sites for the Artemis III mission, which is slated to be the first human landing of the Artemis program.
