Depressed, and aging fast
Older adults with depression are actually aging faster than their peers, researchers report. They also have poor cardiovascular and brain health.
Optical switching at record speeds opens door for ultrafast, light-based electronics and computers
Imagine a home computer operating 1 million times faster than the most expensive hardware on the market. Now, imagine that being the industry standard. Physicists hope to pave the way for that reality.
Phytoplankton blooms offer insight into impacts of climate change
The first study into the biological response of the upper ocean in the wake of South Pacific cyclones could help predict the impact of warming ocean temperatures, researchers believe.
Known active ingredient as new drug candidate against mpox
Mpox — previously known as ‘monkeypox’ — is currently spreading worldwide. Researchers have now identified a compound that could help fight the disease.
Global experts propose a path forward in generating clean power from waste energy
Scientists have created a comprehensive ‘roadmap’ to guide global efforts to convert waste energy into clean power.
Integrated structural biology provides new clues for cystic fibrosis treatment
The cystic fibrosis transmembrane conductance regulator has been studied for years but the new efforts have yielded important insights.
Telomere shortening — a sign of cellular aging — linked to signs of Alzheimer’s in brain scans
Changes in the brain caused by Alzheimer’s disease are associated with shortening of the telomeres — the protective caps on the ends of chromosomes that shorten as cells age — according to a new study.
Road noise makes your blood pressure rise — literally
If you live near a busy road you might feel like the constant sound of roaring engines, honking horns and wailing sirens makes your blood pressure rise. Now a new study confirms it can do exactly that.
‘Biohybrid’ device could restore function in paralyzed limbs
Researchers have developed a new type of neural implant that could restore limb function to amputees and others who have lost the use of their arms or legs. In a study carried out in rats, researchers from the University of Cambridge used the device to…
Geoscientists shed a light on life’s evolution 800 million years ago
Is nitrate responsible for algae, flowers, and even your neighbors? A team of geoscientists have unearthed evidence that may indicate yes.
Robot caterpillar demonstrates new approach to locomotion for soft robotics
Researchers have demonstrated a caterpillar-like soft robot that can move forward, backward and dip under narrow spaces. The caterpillar-bot’s movement is driven by a novel pattern of silver nanowires that use heat to control the way the robot bends, a…
From mutation to arrhythmia: Desmosomal protein breakdown as an underlying mechanism of cardiac disease
Mutations in genes that form the desmosome are the most common cause of the cardiac disease arrhythmogenic cardiomyopathy (ACM), which affects one in 2000 to 5000 people worldwide. Researchers have now discovered how a mutation in the desmosomal gene p…
