Accelerator programs have more work to do when it comes to supporting women entrepreneurs, research finds‎

Accelerator programs are supposed to give entrepreneurs the mentorship, training and skills boost that will help launch them toward success. But in countries where the gender playing field still steeply tilts toward male advantage, women-led businesses that participated in accelerators showed no financial improvement, or even did worse, compared to ventures that applied but weren't accepted.

Scientists study radiation limits for safer seafood shipping‎

Scientists at Florida International University have identified a promising way to safely ship fish long distances without losing vital vitamin D, using a method already widely applied to preserve other foods—gamma irradiation.

Cell lineage tracing reveals early‑segregated germline in plants‎

August Weismann's germ plasm theory of the late 19th century posited that only germ cells, e.g., sperm and egg cells in animals or pollen and ovule cells in plants, transmit genetic information to the next generation, and that somatic mutations represent an evolutionary dead end. This theory has been highly validated in animals, whose germ cells are formed and segregated early in the organism's development.

The unseen challenges of life on the moon‎

For the first time since the Apollo era, humans are preparing not just to visit the moon, but to live and work there for weeks, months—and eventually years.

Dalí's 'sublime' amber medium may explain unusual aging in a museum masterpiece‎

As part of the FED-tWIN Face-to-Face project, a multidisciplinary team bringing together the European Centre of Archaeometry (University of Liège, ULiège), the Royal Museums of Fine Arts of Belgium (RMFAB), CNRS-Sorbonne University and Ca' Foscari University of Venice has published a study on the conservation condition of "The Temptation of St Anthony" (1946) by Salvador Dalí, a major work held by the RMFAB since 1965.

Platform for precise cellular control uses non-genetic DNA decoupled from genetic information‎

Stepping away from its billions-of-years-old role as a genetic blueprint, DNA is now embarking on a new journey as an active field agent within cells. This research by a team led by Professor Jongmin Kim and Ph.D. candidate Geonhu Lee from the Department of Life Sciences at POSTECH (Pohang University of Science and Technology) was published in Nature Chemistry.

Q&A: Is the world really running out of chocolate?‎

Chocolate prices have jumped again this Easter, and it has a lot of people concerned about how much higher they can go—and why they are so high in the first place.

Engineered E. coli dependency may help contain microbes to defined areas‎

Take a typical fish out of the water and it won't live long. It gets the oxygen it needs from the water it swims in. In a similar way, scientists are exploring dependency as a method of controlling what microbes can do and where they can do it.

New 2D material demonstrates capability for ultrathin waveplates‎

Polarization has always been a core property of light that is essential for a broad range of everyday applications, including displays (LED, LCD, 3D Cinematics), photography, as well as satellite and antenna technologies. The ability to tune light polarization empowers us with enhanced communication signals, improved image quality, and access to hidden image details and non-conventional imaging modes (e.g. 3D imaging).

Want to be a citizen scientist? Here are five ways to get involved‎

Ever wondered what it might feel like to spot giant spider crabs while you're snorkeling? Or check plants for the circular holes that indicate native bees are collecting nest materials? Citizen science relies on people like you—more than a million of them in Australia, actually—to collect and analyze valuable data about the world around us.
