New research shows wheat is more sensitive to heat waves before flowering, but later heat waves reduce grain weight after an early heat wave. Sequential heat waves may also provide 'priming' protection against later heat waves.
Researchers from Kyushu University used high-power lasers to recreate magnetic reconnection in a controlled environment. Their study shows that reconnection rates are governed by local physics, not plasma properties, providing experimental benchmarks for testing theoretical models.
Researchers at KRICT developed a method to turn hemp hurd waste into a reinforcing material, improving biodegradable film strength by 26% and reducing moisture and oxygen barrier failures. The technology could be applied to other large-volume agricultural residues, such as soybean stalks and rice straw.
Research shows ultrasound stimulation can reduce passive stiffness in the soleus, a deep calf muscle, suggesting potential for non-invasive management of deep muscle stiffness. The technique also shows promise for preventing sports-related muscle injuries.
A large-scale study found that chronic stress triggers hidden inflammation in the heart, leading to structural changes and increased risk of heart attacks and stroke. Higher levels of inflammation were associated with socioeconomic disadvantage, psychological distress, and established risk factors like smoking and excess body fat.
