Emissive supramolecular metallacages via coordination-driven self-assembly

Metallacages prepared via coordination-driven self-assembly have received extensive attention because of their three-dimensional layout and cavity-cored nature. The construction of light-emitting materials employing metallacages as a platform has also gained significant interest due to their good modularity in photophysical properties, which bring emerging applications in fields as diverse as...

3D 'bioprinting' used to create nose cartilage

A team of University of Alberta researchers has discovered a way to use 3-D bioprinting technology to create custom-shaped cartilage for use in surgical procedures. The work aims to make it easier for surgeons to safely restore the features of skin cancer patients living with nasal cartilage defects after surgery.

Your stomach may be the secret to fighting obesity

Scientists believe a stomach-specific protein plays a major role in the progression of obesity, according to new research. The study could help with development of therapeutics that would help individuals struggling with achieving and maintaining weight loss.

No surge testing for India variants despite Hancock pledge

Following health secretary’s statement last month, Public Health England confirms it is carrying out ‘targeted testing’ insteadCoronavirus – latest updatesSee all our coronavirus coverageSurge testing is not being carried out in England for coronavirus variants first detected in India, despite the government claiming it would be deployed, the Guardian has learned.The coronavirus variant...

Breakthrough study shows no-take marine reserves benefit overfished reefs

A powerful, long-term study from WCS adds scientific backing for global calls for conserving 30 percent of the world's ocean. The studied no-take marine protected areas (MPAs) increased the growth of fish populations by 42 percent when fishing was unsustainable in surrounding areas, achieving the benefits of stable and high production of fish populations for fishers, while protecting threatened...

Soybean cyst nematode is the most damaging soybean pathogen—and it's rapidly spreading

The soybean cyst nematode (SCN) is the most damaging pathogen of soybeans in the United States and Canada and it is spreading rapidly, according to information compiled by Gregory Tylka and Christopher Marett, nematologists at Iowa State University. SCN was first found in the United States in 1954 and most recent estimates show that SCN results in $1.5 billion in annual yield losses.

New neuroimaging technique studies brain stimulation for depression

Despite increased use of repetitive transcranial magnetic stimulation in psychiatry, the rates at which patients respond to the therapy and experience remission of often-disabling symptoms have been modest at best. Now, a team of psychiatrists and biomedical engineers applied an emerging functional neuroimaging technology, known as diffuse optical tomography (DOT), to better understand how rTMS...

The sensitive brain at rest

You know that raw overwhelm people have been reporting after months of a pandemic, compounded by economic issues and social unrest? Does fatigue and compulsive social media scrolling strike a familiar chord?

New graphite-based sensor technology for wearable medical devices

Researchers have developed next-generation, graphene-based sensing technology using their innovative G-Putty material. The team's printed sensors are 50 times more sensitive than the industry standard and outperform other comparable nano-enabled sensors in an important metric seen as a game-changer in the industry: flexibility.
