The evidence is building that the surface of Mars was warm and wet for its early history. But what form did this water take? In a new study, geologists propose that Mars has very similar features to places like Utah on Earth, where precipitation from snow or rain formed the patterns of valleys and headwaters that have been mapped from space. Some of these features would require meters deep of flowing water to deposit large boulders.

Machine learning helped show how harnessing the weird effects of Einstein’s special relativity could enable a new kind of quantum computer – and it could also lead to new insights into the quantum realm

Researchers have developed a new robotic framework powered by artificial intelligence -- called RHyME (Retrieval for Hybrid Imitation under Mismatched Execution) -- that allows robots to learn tasks by watching a single how-to video.

Genome editing has advanced at a rapid pace with promising results for treating genetic conditions -- but there is always room for improvement. A new paper showcases the power of scalable protein engineering combined with machine learning to boost progress in the field of gene and cell therapy. In their study, authors developed a machine learning algorithm -- known as PAMmla -- that can predict the properties of about 64 million genome editing enzymes. The work could help reduce off-target effects and improve editing safety, enhance editing efficiency, and enable researchers to predict customized enzymes for new therapeutic targets.

A new tissue expansion method enables scientists to use mass spectrometry imaging to simultaneously detect hundreds of molecules at the single cell level in their native locations.

Let’s turn the sun into a telescope. In fact, we don’t have to do any work – we just have to be in the right spot.

Studying the Sun is becoming increasingly important as more and more of our infrastructure moves off the surface and into the realm where coronal mass ejections and the solar wind can begin to affect them. Scientists recognize this problem and have started devoting more and more resources to studying the Sun, specifically the "space weather" that might affect us. Recently, one of the newest members of the group of satellites focused on studying the Sun hit a milestone when the Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission took on its first light.

The game, called StarStarter, rewards players for directing their attention away from negative stimuli and towards positive ones

Planetary scientists have plenty of theories about Mars and its environmental past. Two of the most widely accepted are that there was a carbon dioxide atmosphere and, at one point, liquid water on Mars' surface. However, this theory has a glaring problem: Where should the rocks have formed from the interactions between carbon dioxide and water? According to a new paper by scientists at several NASA facilities using data collected by the rover Curiosity, the answer is right under the rover's metaphorical feet.

A huge colony of Pavona coral near the coast of Saudi Arabia is thought to be the largest living example found in the Red Sea

With the assumption that students are going to use artificial intelligence and large language models such as ChatGPT to do their homework, researchers set out to learn how well the free version of ChatGPT would compare with human students in a semester-long undergraduate control systems course.

Researchers introduced a novel method for fabricating functional flat-to-shape objects using a computer-controlled sewing machine. The team's method uses the sewing machine to stitch pockets between layers of fabric, and stiff panels are inserted into the pockets. Multiple fabrics types can be used, ranging from muslin for heavy-duty applications to more delicate fabrics for decorative purposes. The materials can also be customized on a panel-by-panel basis to adapt to each object's needs. The researchers demonstrated how the materials can be chosen to support a variety of functional goals, such as using thicker plywood for a human-weight supporting chair and custom LED panels with sheer fabric for a functional lamp. Additionally, The technique also allows for additional mechanisms such as cords, magnets, and hook-and-loop fasteners to direct and stabilize flat-to-shape transitions.

Researchers document a multi-faceted global snapshot of the environmental aspects and trends surrounding single-use plastics in a review article. The researchers state that the largest area of application for biodegradable plastic materials is the packaging segment, which accounts for about half of single-use plastic production.

Researchers have developed a light-induced DNA detection method that enables rapid, PCR-free genetic analysis. Their technique offers ultra-sensitive mutation detection in just five minutes, reducing costs and simplifying testing. The method has significant potential in healthcare, environmental conservation, and personal health monitoring.

Researchers explored a colloidal crystal model to produce specific polymorphs, required for use in materials science and pharmaceuticals.

Researchers have developed a new artificial intelligence (AI) technique that brings machine vision closer to how the human brain processes images. Called Lp-Convolution, this method improves the accuracy and efficiency of image recognition systems while reducing the computational burden of existing AI models.

Asymmetric interactions between molecules may serve as a stabilizing factor for biological systems. A new model reveals this regulatory role of non-reciprocity. The scientists aim to understand the physical principles based on which particles and molecules are able to form living beings and, eventually, organisms.

Financial benefits, such as saving on utility payments and avoiding electricity rate hikes, are a key driver of U.S. adults' willingness to consider installing rooftop solar panels or subscribing to community solar power, a new study suggests.

Researchers have made a breakthrough discovery that could potentially revolutionize treatments for antibiotic-resistant infections, cancer and other challenging gram-negative pathogens without relying on precious metals.
