Published Non-stop flight: 4,200 km transatlantic flight of the Painted Lady butterfly mapped



In October 2013 a researcher made a surprising discovery of Painted Lady Butterflies on the Atlantic beaches of French Guiana -- a species not typically found in South America. This unusual sighting prompted an international study to investigate the origin of these butterflies.
Published Discovery of vast sex differences in cellular activity has major implications for disease treatment



The study reveals vast differences in gene activity within the mitochondria of males compared to females. This is the first study to test effects of all 37 genes in the mitochondrial genome -- genes that copepods and humans share. The study found that males demonstrate more activity across all protein-coding mitochondrial genes than females. Although the study looks at tiny marine organisms called copepods, the findings have weighty implications for human medicine.
Published Your future medications could be personalized for you on a 3D printer



Scientists are helping to develop standards and safety protocols that would allow pharmacies to print drugs onsite at a dosage best for you.
Published Next platform for brain-inspired computing



Computers have come so far in terms of their power and potential, rivaling and even eclipsing human brains in their ability to store and crunch data, make predictions and communicate. But there is one domain where human brains continue to dominate: energy efficiency.
Published Moving objects precisely with sound



Researchers have succeeded in directing floating objects around an aquatic obstacle course using only soundwaves. Their novel, optics-inspired method holds great promise for biomedical applications such as noninvasive targeted drug delivery.
Published Telltale greenhouse gases could signal alien activity



If aliens modified a planet in their solar system to make it warmer, we'd be able to tell. A new study identifies the artificial greenhouse gases that would be giveaways of a terraformed planet.
Published Robots face the future



Researchers have found a way to bind engineered skin tissue to the complex forms of humanoid robots. This brings with it potential benefits to robotic platforms such as increased mobility, self-healing abilities, embedded sensing capabilities and an increasingly lifelike appearance. Taking inspiration from human skin ligaments, the team included special perforations in a robot face, which helped a layer of skin take hold.
Published 3D-printed chip sensor detects foodborne pathogens for safer products



Researchers have developed a new method for detecting foodborne pathogens that is faster, cheaper, and more effective than existing methods. Their microfluidic chip uses light to detect multiple types of pathogens simultaneously and is created using 3D printing, making it easy to fabricate in large amounts and modify to target specific pathogens. The researchers hope their technique can improve screening processes and keep contaminated food out of the hands of consumers.
Published Should you eat more dietary fiber? New study says it depends



Nutritionists generally advise everyone to eat more dietary fiber, but a new study suggests that its effects on health can vary from person to person. The findings indicate that recommendations should be tailored to each individual's gut microbiome.
Published First of its kind detection made in striking new Webb image



For the first time, a phenomenon astronomers have long hoped to directly image has been captured by NASA's James Webb Space Telescope's Near-Infrared Camera (NIRCam). In this stunning image of the Serpens Nebula, the discovery lies in the northern area of this young, nearby star-forming region.
Published Meet CARMEN, a robot that helps people with mild cognitive impairment



Meet CARMEN, short for Cognitively Assistive Robot for Motivation and Neurorehabilitation -- a small, tabletop robot designed to help people with mild cognitive impairment (MCI) learn skills to improve memory, attention, and executive functioning at home.
Published Geologists expect Chang'e-6 lunar surface samples to contain volcanic rock and impact ejecta



On June 25, China's Chang'e-6 (CE-6) lunar probe is set to return to Earth, carrying the first surface samples collected from the farside of the Moon. In anticipation of this historic event, scientists are publishing their predictions for the unique materials that may be found in the CE-6 samples.
Published Myths about intermittent fasting, debunked



Research shows that the increasingly popular weight-loss strategy is safe. Intermittent fasting has become an increasingly popular way to lose weight without counting calories. And a large body of research has shown it s safe. Still, several myths about fasting have gained traction.
Published Mashed up purple marine bacteria makes an excellent eco-friendly fertilizer



New research reports that biomass made from the purple photosynthetic marine bacterium Rhodovulum sulfidophilum is an excellent nitrogen fertilizer. The biomass fertilizer proved to be just as effective as common inorganic synthetic fertilizers but avoids several side effects that harm the environment, making it an eco-friendly alternative.
Published Removal of excess chloride ions by plants when subjected to salt stress



Researchers have discovered a salt adaptation mechanism in plants that facilitates chloride removal from the roots and enhancing salinity tolerance. A research team has uncovered a novel mechanism of plant adaptation to salt stress involving the NaCl-induced translocation of a specific chloride channel protein, AtCLCf.
Published A hidden treasure in the Milky Way -- Astronomers uncover ultrabright x-ray source



Astronomers uncovered that a well-known X-ray binary, whose exact nature has been a mystery to scientists until now, is actually a hidden ultraluminous X-ray source.
Published How cells boost gene expression



The function of non-coding RNA in the cell has long been a mystery to researchers. Unlike coding RNA, non-coding RNA does not produce proteins -- yet it exists in large quantities. A research team has now discovered an important function of antisense RNA (asRNA): the researchers found that asRNA acts as a 'superhighway' in cell transport and thus accelerates gene expression.
Published New tomato, potato family tree shows that fruit color and size evolved together



A new family tree of the plant genus Solanum helps explain the striking diversity of their fruit color and size. This genus includes tomatoes, potatoes, eggplants, and other economically important plants.
Published Star clusters observed within a galaxy in the early Universe



The history of how stars and galaxies came to be and evolved into the present day remains among the most challenging astrophysical questions to solve yet, but new research brings us closer to understanding it. New insights about young galaxies during the Epoch of Reionization have been revealed. Observations with the James Webb Space Telescope (JWST) of the galaxy Cosmic Gems arc (SPT0615-JD) have confirmed that the light of the galaxy was emitted 460 million years after the big bang. What makes this galaxy unique is that it is magnified through an effect called gravitational lensing, which has not been observed in other galaxies formed during that age.
Published Innovative 3D printing method streamlines multi-materials manufacturing



Researchers have developed a way to create complex devices with multiple materials -- including plastics, metals and semiconductors -- all with a single machine. The research outlines a novel 3D printing and laser process to manufacture multi-material, multi-layered sensors, circuit boards and even textiles with electronic components.
