Drying without dying: How resurrection plants survive without water

Figure 1. Haberlea rhodopensis, a resurrection plant species, was used as a model system to study the underlying mechanisms of extreme desiccation tolerance. Credit: Kobe University A small group of plants known as "resurrection plants" can survive months or even years without water. The research team of Kobe University's Graduate School of Agricultural Science, led…

Simply shining light on ‘dinosaur metal’ compound kills cancer cells

Iridium with its organic coat which is hooked up to the protein albumin (HSA). Together that enter cancer cells and deliver the iridium photosensitizer to the nucleus. On irradiation with blue light, the iridium not only glows green, but converts oxygen in the cell to a toxic form called triplet oxygen, which kills the cell.…

Exiled planet linked to stellar flyby 3 million years ago

The HD 106906 binary star hosts a mysterious, asymmetric disk of cometary dust and a giant exoplanet HD 106906 b that is located very far from both the binary and the disk. Close flybys by other stars could have gravitationally perturbed the planet and researchers discovered that the two bright stars to the upper right…

New hurdle cleared in race toward quantum computing

The findings could pave the way for development of topological qubits. Credit: Purdue University/James Nakamura Qubits, the units used to encode information in quantum computing, are not all created equal. Some researchers believe that topological qubits, which are tougher and less susceptible to environmental noise than other kinds, may be the best medium for pushing…

Researchers uncover new structures at plant-fungal interface

The interface between plant roots and their symbiotic fungi are full of membrane tubules both in the fungus (yellow) and between the plant cell membrane and the fungal cell wall (green). The fungal cell membrane is red, and the plant cell membrane is gray. Credit: Jotham Austin II and R. Howard Berg For hundreds of…

Citizen scientist finds ancient white dwarf star encircled by puzzling rings

In this illustration, an asteroid (bottom left) breaks apart under the powerful gravity of LSPM J0207+3331, the oldest, coldest white dwarf known to be surrounded by a ring of dusty debris. Scientists think the system's infrared signal is best explained by two distinct rings composed of dust supplied by crumbling asteroids. Credit: NASA's Goddard Space…

Mobile bedside bioprinter can heal wounds

A close up view of the skin bioprinter nozzle. Credit: WFIRM photo Imagine a day when a bioprinter filled with a patient's own cells can be wheeled right to the bedside to treat large wounds or burns by printing skin, layer by layer, to begin the healing process. That day is not far off. Wake…

Earliest example of animal nest sharing revealed by scientists

Two of the fossilized enantiornithine eggs. Credit: Gareth Dyke An international team of scientists, including researchers from the University of Southampton, has shown that fossilised eggshells unearthed in western Romania represent the earliest known nest site shared by multiple animals. The shells -- some complete and others broken into thousands of pieces -- are densely…

Weighing as much as a raindrop, the chest sensor can wirelessly monitor heart rate, breathing rate, and temperature. Credit: Northwestern University An interdisciplinary Northwestern University team has developed a pair of soft, flexible wireless sensors that replace the tangle of wire-based sensors that currently monitor babies in hospitals' neonatal intensive care units (NICU) and pose…

Psychedelic microdosing in rats shows beneficial effects

Crystals of N,N¬-dimethyltryptamine (DMT) imaged with polarizing microscopy. DMT is the active ingredient in the hallucinogenic drug ayahuasca. New studies from UC Davis using a rat model show that 'microdosing' or taking small doses of a psychedelic drug that do not cause hallucinations may have beneficial effects for mental health.

Ancient asteroid impacts played a role in creation of Earth’s future continents

A model for the compositional evolution of the early Earth's crust due to fractional crystallization of impact melt sheets followed by detachment and sinking of their dense primitive portions towards the crust-mantle boundary. Credit: Rais Latypov The heavy bombardment of terrestrial planets by asteroids from space has contributed to the formation of the early evolved…

How new species arise in the sea

A barred Hamlet (Hypoplectrus puella) off the coast of Panama. Credit: Kosmas Hench/GEOMAR For a new species to evolve, two things are essential: a characteristic -- such as a colour -- unique to one species and a mating preference for this characteristic. For example, individuals from a blue fish species prefer blue mates and individuals…

The case of the over-tilting exoplanets

Yale researchers have discovered a surprising link between the tilting of exoplanets and their orbit in space. The discovery may help explain a long-standing puzzle about exoplanetary orbital architectures. Credit: NASA/JPL-Caltech, Sarah Millholland For almost a decade, astronomers have tried to explain why so many pairs of planets outside our solar system have an odd…

Now you see heat, now you don’t

A hot object can be fully hidden from infrared detection by adding polyethylene glycol to an aerogel film.

Applying a network perspective to human physiology

Medical practitioners commonly treat organs in isolation, but Boston University physicist Plamen Ivanov wants to usher in a new paradigm. As he will describe at the 2019 APS March Meeting, 'It's time to view health and disease not only from the perspective of individual organs but from the point of view of their integration,' he…
