Why human connection is the true metric of research success
FEBS Open Bio, EarlyView.Human‐centred mentorship can be shaped by mentor attributes, actions, intrinsic drive and career ambition. Drawing on reflections across Singapore and France, as well as workshop insights from FEBS‐IUBMB ENABLE 2024, this article shows that human‐centred mentorship creates the conditions for sustainable growth, well‐being and retention in research ...

Demo 22-18 Ray Tracing with Lenses [PDF]
, 2001 A light box is used with several incoming parallel rays to trace the rays through focusing and defocusing lenses and to observe the focal properties of the lenses. A plano-convex lens focuses parallel rays to a point as shown in Figure 1, and is compared

Laboratory evaluation of blended lenticular aphakic lenses [PDF]
, 1988 Six types of blended lenticular aspheric lenses for the correction of aphakia were assessed with respect to mass, spectacle magnification, off-axis power errors, peripheral distortion, visual field size and cosmetic appearance.

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens
FEBS Open Bio, EarlyView.Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Demo 22-20 Fillable Air Lenses [PDF]
, 2001 Hollow convex and concave lenses inserted into water function opposite to normal glass lenses in air. A double concave air lens is shown in the video to focus light under water, as seen in Figure 1, but to defocus light when filled with water and used in

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death
FEBS Open Bio, EarlyView.Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Immersion Meta-Lenses at Visible Wavelengths for Nanoscale Imaging.
Nano letters (Print), 2017 Immersion objectives can focus light into a spot smaller than what is achievable in free space, thereby enhancing the spatial resolution for various applications such as microscopy, spectroscopy, and lithography. Despite the availability of advanced lens
