Scientists design new bio-inspired molecules to promote bone regeneration

People's ability to regenerate bones declines with age and is further decreased by diseases such as osteoporosis. To help the aging population, researchers are looking for new therapies that improve bone regeneration.

Combining observations to better visualize a superflare

A team of Japanese astronomers used simultaneous ground-based and space-based observations to capture a more complete picture of a superflare on a star. The observed flare started with a very massive, high-velocity prominence ...

Mushrooms and their post-rain, electrical conversations

Certain fungi play a critical role in the ecological sustenance of forest trees. Ectomycorrhizal fungi are one such example. Commonly found on pine, oak, and birch trees, ectomycorrhizal fungi form a sheath around the outside ...

Understanding the role of octopamine in neurodegeneration

Northwestern Medicine scientists have discovered how octopamine, the major "fight-or-flight" neurotransmitter in invertebrates, communicates with other cells in mammalian brains to prevent cell death, according to a study ...

Second ring found around dwarf planet Quaoar

A large international team of astronomers has discovered that the dwarf planet Quaoar is circled by a second ring. In their study, accepted for publication in the journal Astronomy & Astrophysics, the group discovered the ...

How a single enzyme unleashes a complex DNA repair process

Our DNA is constantly exposed to damaging factors that can lead to aging and age-related diseases such as cancer. PARP1 is an important enzyme that facilitates the response to DNA damage by attaching chemical groups called ...

Fallow land found to promote bird biodiversity

In recent decades, many of Germany's animal populations in agricultural landscapes have experienced sharp declines, both in terms of the number of species and the number of individuals. Fallow land is considered an effective ...

Dynamic 3D structure extraction from HS-AFM images

Allowing the direct observation of biomolecules in dynamic action, high-speed AFM has opened a new avenue to dynamic structural biology. An enormous number of successful applications developed within the last 15 years provide ...

'Smart mines' show coal deeply embedded in China's future

One hundred meters underground inside a pit in northern China, miners extract lumps of coal with the flick of a finger on a smartphone, as the country tries to drag the traditionally dangerous and dirty work into the digital ...

Meltdown: 2023 looking grim for Swiss glaciers

This year is already shaping up to be another bad one for glaciers in the Swiss Alps, with the snowpack covering them around 30 percent below the 10-year average, according to the scientist tracking their decline.

Hubble captures galaxy cluster ACO S520

A menagerie of interesting astronomical finds are visible in this image from the NASA/ESA Hubble Space Telescope. In addition to several large elliptical galaxies, a ring-shaped galaxy is lurking on the right of the image. ...

Single-celled alga found to harbor seven genomes

An international team of oceanographers, parasitologists and biologists has found that the single-celled alga Cryptomonas gyropyrenoidosa harbors seven genomes in its one cell. In their study, reported in the journal Current ...

Silence reveals insights in search for extraterrestrial life

The search for radio signals from extraterrestrial civilizations has yet to yield evidence of alien technological activity. Research carried out at EPFL suggests we continue searching while optimizing the use of available ...

What is the Fluidic Telescope?

The Fluidic Telescope (FLUTE) project team, jointly led by NASA and Technion–Israel Institute of Technology, envisions a way to make huge circular self-healing mirrors in-orbit to further the field of astronomy. Larger ...

Structural insight into process of gene regulation

In the cell nucleus, numerous proteins bind to the DNA molecule in order to regulate the activity of certain genes. One of these is the TATA-box binding protein (TBP), which binds to a specific DNA sequence and constitutes ...

Quack 'aphrodisiac' from lizard a hit in Pakistan

In a clamorous bazaar, hot-blooded Pakistani men seek a cold-blooded cure for their sexual ills—freshly rendered lizard fat, marinated in scorpion oil and garnished with filaments of a fiery red spice.

When employees leave their jobs, coworkers call it quits

People leave jobs all the time, whether they're laid off, fired, or just quit. But how do their departures affect coworkers left behind? According to a new study from the UBC Sauder School of Business, those exits can lead ...
