Published Barnacles may help reveal location of lost Malaysia Airlines flight MH370



Geoscientists have created a new method that can reconstruct the drift path and origin of debris from flight MH370, an aircraft that went missing over the Indian Ocean in 2014 with 239 passengers and crew.
Published Newly discovered 'primitive cousins of T rex' shed light on the end of the age of dinosaurs in Africa



Researchers have discovered the fossils of two new abelisaurs in Morocco, showing the diversity of dinosaurs in this region at the end of the Cretaceous period.
Published How artificial intelligence gave a paralyzed woman her voice back


Researchers have developed a brain-computer interface (BCI) that has enabled a woman with severe paralysis from a brainstem stroke to speak through a digital avatar.
Published This fish doesn't just see with its eyes -- it also sees with its skin



Without a mirror, it can be hard to tell if you're blushing, or have spinach in your teeth. But one color-changing fish has evolved a clever way to keep watch on the parts of itself that lie outside its field of view -- by sensing light with its skin.
Published Heat sensor protects the Venus flytrap from fire



The sensory hairs of the Venus flytrap contain a heat sensor that warns the plant of bush fires. It reacts to rapid temperature jumps, as researchers have discovered.
Published Researchers extract ancient DNA from a 2,900-year-old clay brick, revealing a time capsule of plant life



For the first time, a group of researchers have successfully extracted ancient DNA from a 2,900-year-old clay brick. The analysis provides a fascinating insight into the diversity of plant species cultivated at that time and place, and could open the way to similar studies on clay material from other sites and time periods.
Published Coffee offers performance boost for concrete



Engineers in Australia have found a way of making stronger concrete with roasted used-coffee grounds, to give the drink-additive a 'double shot' at life and reduce waste going to landfills. The team developed a technique to make concrete 30% stronger by turning waste coffee grounds into biochar, using a low-energy process without oxygen at 350 degrees Celsius.
Published Did sabertooth tigers purr or roar?



When a sabertooth tiger called out, what noise did it make -- a mighty roar or a throaty purr? A new study examined the data behind the arguments for each vocalization and found that the answer was more nuanced than they thought -- and that it could depend on the shape of a few small bones.
Published Transforming flies into degradable plastics



Imagine using insects as a source of chemicals to make plastics that can biodegrade later -- with the help of that very same type of bug. That concept is closer to reality than you might expect. Researchers will describe their progress to date, including the isolation and purification of the insect-derived chemicals and their conversion into their bioplastics.
Published 3D-printed vegan seafood could someday be what's for dinner



More mock seafood options are needed because of unsustainable fishing and aquaculture practices, which can harm the environment. Now, researchers have a new approach for creating desirable vegan seafood mimics that taste good, while maintaining the healthful profile of real fish. They 3D-printed an ink made from microalgae protein and mung bean protein, and their proof-of-concept calamari rings were air-fried into a snack.
Published Tattoo technique transfers gold nanopatterns onto live cells


For now, cyborgs exist only in fiction, but the concept is becoming more plausible as science progresses. And now, researchers are reporting that they have developed a proof-of-concept technique to 'tattoo' living cells and tissues with flexible arrays of gold nanodots and nanowires. With further refinement, this method could eventually be used to integrate smart devices with living tissue for biomedical applications, such as bionics and biosensing.
Published Fossil feces infested with parasites from over 200 million years ago



Fossilized feces preserve evidence of ancient parasites that infected an aquatic predator over 200 million years ago, according to a new study.
Published The 'unknome': A database of human genes we know almost nothing about



Researchers hope that a new, publicly available database they have created will shrink, not grow, over time. That's because it is a compendium of the thousands of understudied proteins encoded by genes in the human genome, whose existence is known but whose functions are mostly not.
Published Quantum material exhibits 'non-local' behavior that mimics brain function


New research shows that electrical stimuli passed between neighboring electrodes can also affect non-neighboring electrodes. Known as non-locality, this discovery is a crucial milestone toward creating brain-like computers with minimal energy requirements.
Published Whale-like filter-feeding discovered in prehistoric marine reptile



A remarkable new fossil from China reveals for the first time that a group of reptiles were already using whale-like filter feeding 250 million years ago.
Published Latest in body art? 'Tattoos' for individual cells



Engineers have developed nanoscale tattoos -- dots and wires that adhere to live cells -- in a breakthrough that puts researchers one step closer to tracking the health of individual cells.
Published Butterflies can remember where things are over sizeable spaces



Heliconius butterflies are capable of spatial learning, scientists have discovered. The results provide the first experimental evidence of spatial learning in any butterfly or moth species.
Published Self-supervised AI learns physics to reconstruct microscopic images from holograms


Researchers have unveiled an artificial intelligence-based model for computational imaging and microscopy without training with experimental objects or real data. The team introduced a self-supervised AI model nicknamed GedankenNet that learns from physics laws and thought experiments. Informed only by the laws of physics that universally govern the propagation of electromagnetic waves in space, the researchers taught their AI model to reconstruct microscopic images using only random artificial holograms -- synthesized solely from 'imagination' without relying on any real-world experiments, actual sample resemblances or real data.
Published Discovery in nanomachines within living organisms -- cytochromes P450 (CYP450s) unleashed as living soft robots



A new study suggests that Cytochromes P450 (CYP450s) enzymes can sense and respond to stimuli, acting like soft robots in living systems.
Published Thermal imaging innovation allows AI to see through pitch darkness like broad daylight


Engineers have developed HADAR, or heat-assisted detection and ranging.
