When the researcher Daniel Kronauer was still a postdoc in 2008, he traveled to Okinawa, Japan, for wild specimens of clonal raider ants (the species Ooceraea biroi). In the first colony he collected, he noticed two ants with a strange appearance. They were small like workers, but they also sported small wing buds, which was striking because usually only ant queens develop wings. Source

Sauropods—including iconic long-necked dinosaurs like Brachiosaurus and Apatosaurus—were the largest animals ever to walk the earth. No other dinosaur or land mammal even comes close. Now, a new Adelphi University study provides insights into how these super giants achieved their record-breaking sizes over time.

Complex multicellular organisms can only emerge from fertilized eggs because embryonic development is biologically precisely regulated. Cellular communication through signaling pathways plays a crucial role in this context. If the activities of the signaling pathways are disturbed, the embryo will show characteristic developmental defects.

Professor Nicolas Doucet and his team at Institut national de la recherche scientifique (INRS) made a major breakthrough earlier this year in the field of evolutionary conservation of molecular dynamics in enzymes.

Half of plant proteins in the EU come from rapeseed plants. Until now, the plant has only been used for oil and animal feed, as it is both bitter and unsafe for human consumption. In a new study published in Nature, University of Copenhagen researchers have gotten closer to removing the plant's bitter substances, and in doing so, are paving the way for a new protein source to support the green tra

Cellulose nanocrystal (CNC), an emerging bio-based material, has been widely applied in fields such as electronics, bioplastics and energy. However, the functional failure of such materials in wet or liquid environments inevitably impairs their development in biomedicine, membrane separation, environmental monitoring, and wearable devices.

It's often risky to introduce new products to the market. In fact, statistics show that between 40 to 90 percent of new products fail. A key component of product adoption is consumer psychology. While there are a few theories that attempt to explain why certain people are not likely to accept novelties, a new study takes a slightly different approach.

The process of filtration makes an appearance in quite a few instances of our daily lives, for example: a strainer filtering out tea leaves while making a cup of tea. The tea leaves, being larger in size than the pores of the strainer, are unable to pass through and consequently get separated out from the hot brew.

Surfactants play an important role in every day life, for instance as major components in soaps. Since they feature hydrophilic and hydrophobic parts in their structure, they accumulate at water interfaces with air and can there influence the rate of evaporation of the solution or the efficiency with which gas molecules are taken up by the solution, a process that is for instance important for the

A time crystal, as originally proposed in 2012, is a new state of matter in which the particles are in continuous oscillatory motion. Time crystals break time-translation symmetry. Discrete time crystals do so by oscillating under the influence of a periodic external parametric force, and this type of time crystal has been demonstrated in trapped ions, atoms and spin systems.

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have observed a pair of galaxies known as Arp 269. They detected extended tidal tails emerging from this system. The finding was reported in a paper published April 28 on the arXiv pre-print repository. The article has been accepted for publication in Monthly Notices of the Royal Astronomical Society.

The United States Food and Drug Administration has authorized gene-edited pigs entrance into the food chain for human consumption—as German-style sausages.

Glycans perform varied and crucial functions in numerous cellular activities. The diverse roles of glycans are matched by their highly complex structures, which derive from differences in composition, branching, regio- and stereochemistry, and modification. This incomparable structural diversity is challenging to the structural analysis of glycans.

Americans are in a cultural battle over school sports. For years, thanks to Title IX, most athletic programs have been divided on the basis of sex.
