RICE has been the default for soft-tissue injuries for decades

Newer framework is PEACE & LOVE

Inflammation isn’t the enemy; it’s essential for repair. Instead of suppressing inflammation, we need to create an environment for healing & progressively reload the injured tissue

A toddler won't move their arm after being pulled. Why?

Nursemaid's elbow: the annular ligament slips over the radial head. Child holds it pronated & won't use it. Hyperpronation reduces it faster than supination/flexion.

Avoid yanking or lifting a child up by their arms.

Half of IF/IHC troubleshooting starts before you pipette: dilution math, hunting freezers for the right Ab tube, notebook entries you'll misread next week.

Built ProtocolPro to fix it. Auto-calculates volumes, tracks antibody inventory by freezer location, flags design mistakes.

Bell’s palsy is a lower motor neuron lesion of the facial nerve (CN VII), causing ipsilateral weakness of both upper & lower face. In contrast, most cortical strokes spare the forehead b/c of its bilateral corticobulbar innervation. Onset is quick (hrs), full recovery is common.

Commotio cordis is a rare cause of sudden cardiac arrest, most often seen in young athletes after a blunt blow to the chest. The impact simply occurs during upstroke of
T wave (20msec window), causing a rapid increase in intracavitary pressure, disrupting its electrical rhythm.

Arthrogryposis: condition where babies are born with multiple stiff, contracted joints. Usually caused by reduced movement (fetal akinesia) due to neuro or muscle disorders, or limited womb space (some twin pregnancies). Reduced movement causes permanent stiffness before birth.

You can actually die from drinking too much water 💦

Chug it faster than your kidneys can process and your blood sodium plummets. It’s called hyponatremia, and it can trigger seizures, coma, or death.

REMEMBER
Everything in moderation… even moderation.

Medical school doesn’t teach you this. They just start using it on day 1.

Miss it and you’ll spend the first few days lost while everyone else follows along.

A THREAD: I've spent almost a decade helping young scientists land their first biotech/pharma jobs. I'm leaving industry for medicine soon, so before I lose touch, here's everything I'd tell you over coffee about getting your foot in the door.

SUMMARY Landing your first role isn't about being perfect. It's about being aligned: right level, real outcomes, TAILORED applications, a LinkedIn that backs you up, referrals, and calm interviews. You've got more to offer than you think. Best of luck hunting in this market :)
