Isoforms of cysteine peptidases and osmotins instead of chitinases and peptidase inhibitors drive antifungal activity but occur as distinct isoforms in latex and callus tissues of Calotropis procera 3:31

Isoforms of cysteine peptidases and osmotins instead of chitinases and peptidase inhibitors drive antifungal activity but occur as distinct isoforms in latex and callus tissues of Calotropis procera

A plant's wound-sealing liquid can fight fungi, but when researchers grew plant tissue outside that liquid, the defense survived in one species and vanished in another. The surprise was not just which proteins worked, but where their versions came from.

Object groups mutually bias each other’s perceived average size, as evidenced by neural and behavioural data 3:15

Object groups mutually bias each other’s perceived average size, as evidenced by neural and behavioural data

When you look at a group of objects, your brain can estimate their average size almost instantly. But that estimate is not fixed: another group nearby can quietly make the first group look larger or smaller.

Multiple discrimination at work and depressive symptoms in young adults 3:40

Multiple discrimination at work and depressive symptoms in young adults

What happens when unfair treatment at work is not just one experience, but several at once? This study links that accumulation with a much higher chance of depressive symptoms.

Comparative evaluation of pyrolysis oils derived from lignocellulosic biomass and municipal solid waste as potential bitumen modifiers 4:46

Comparative evaluation of pyrolysis oils derived from lignocellulosic biomass and municipal solid waste as potential bitumen modifiers

What if part of the answer to cleaner roads came from things we usually throw away, or sweep off the ground? This study finds that the source of that waste may matter more than expected.

Dispersal diversity buffers species vulnerability to local extinction 4:09

Dispersal diversity buffers species vulnerability to local extinction

A species can look safe simply because it is numerous, but that headcount can miss the real danger. Its chances may depend on how differently its members move through space, and on the other species around them.

Considering Autism in Binge-Type Eating Disorders: Broadening Beyond an Anorexia Nervosa-Focused Model 5:06

Considering Autism in Binge-Type Eating Disorders: Broadening Beyond an Anorexia Nervosa-Focused Model

What if binge eating is being treated with a model built mainly around anorexia? This review suggests that autism can be missed in binge-type eating disorders, leaving important needs unaddressed.

Back in time: starting the KS3 history curriculum in the 2 nd century AD 3:59

Back in time: starting the KS3 history curriculum in the 2 nd century AD

What if a child’s first lesson in secondary-school history began not in 1066, but nearly a thousand years earlier? One proposal says that starting with Roman Britain could make history more accurate, more inclusive, and open to more students.

Starvation transforms signal encoding in C. elegans thermoresponsive neurons and suppresses heat avoidance via bidirectional glutamatergic and peptidergic signaling 5:03

Starvation transforms signal encoding in C. elegans thermoresponsive neurons and suppresses heat avoidance via bidirectional glutamatergic and peptidergic signaling

What if hunger could turn down an animal’s heat alarm, not just making the warning quieter, but changing the alarm’s pattern so escape is no longer the default?

Structural and Evolutionary Analysis of Non-specific Lipid Transfer Proteins (nsLTPs) in Cereus (Cactaceae) 3:22

Structural and Evolutionary Analysis of Non-specific Lipid Transfer Proteins (nsLTPs) in Cereus (Cactaceae)

A cactus survives harsh heat and drought with proteins that may act like tiny gates: their main structure stays stable, while the entrances subtly change what can pass through.

Sub-nanosecond structural dynamics of the martensitic transformation in Ni-Mn-Ga 3:55

Sub-nanosecond structural dynamics of the martensitic transformation in Ni-Mn-Ga

Some metals can change their internal structure almost instantly, and that motion can power tiny machines. This study finds a complete switching cycle in just five nanoseconds.

Paint outside the box: synthesizing and selecting training data for visual grounding 4:48

Paint outside the box: synthesizing and selecting training data for visual grounding

Teaching a computer to find the exact object described in a sentence usually demands vast amounts of carefully labeled pictures. This paper shows how carefully made artificial examples can help when those pictures are scarce.

Specialists’ agreement and construct validation of a visual scale for assessing mucosal healing after third molar extraction 3:52

Specialists’ agreement and construct validation of a visual scale for assessing mucosal healing after third molar extraction

After a wisdom tooth is removed, two dental professionals can look at the same healing wound and judge it differently. This study asks whether a shared set of pictures can make that judgment clearer.
