Strong Link Found Between Concussions And Brain Tissue Injury
- ScienceDaily
- 09/8/25 05:00
Concussions, whether from an accident, sporting event, or combat, can lead to permanent loss of higher level mental processes. Scientists have debated for centuries whether concussions involve structural damage to brain tissue or whether physiological changes that merely impair the way brain cells function, explain this loss. Now, for the first time, researchers have linked areas of brain injury...

Blossoms Of Maturity: Newly Discovered Signaling Pathway Ensures That Plants Remember To Flower
- ScienceDaily
- 09/8/25 05:00
Plants normally flower in response to seasonal changes, such as those associated with the end of winter or beginning of spring. Scientists have now identified a signaling pathway that allows plants to blossom even without positive signals from the environment. The concentration of a small RNA snippet in plants cells operates like an hour glass: a decline in its level awakes the plant from its...

Many Online Social Networks Leak Personal Information To Tracking Sites, New Study Shows
- ScienceDaily
- 09/8/25 05:00
More than a half billion people use online social networks, posting vast amounts of information about themselves to share with online friends and colleagues. A new study has found that the practices of many popular social networking sites typically make that personal information available to companies that track Web users' browsing habits, and allow them to link anonymous browsing habits to...
Retina Cells Created From Skin-derived Stem Cells
- ScienceDaily
- 09/8/25 05:00
Scientists have successfully grown multiple types of retina cells from two types of stem cells -- suggesting a future in which damaged retinas could be repaired by cells grown from the patient's own skin.
Scientists Shed New Light On Behavior Of Shark 'Tweens' And 'Teenagers'
- ScienceDaily
- 09/8/25 05:00
Marine biologists have shown that young lemon sharks born in Bimini, Bahamas, tend to stay near their coastal birthplace for many years. Knowledge about these intermediate-aged animals -- the breeders of tomorrow -- has been limited. Thus, tropical island-nations that sacrifice their nursery habitats to coastal development are therefore likely to lose both babies and much older sharks, with...
Saying 'I'm Sorry' Influences Jurors
- ScienceDaily
- 09/8/25 05:00
Apologizing for negative outcomes -- a practice common even with children -- may lead to more favorable verdicts for auditors in court, according to researchers.
Why 'Thick' Blood Protects From A Heart Attack
- ScienceDaily
- 09/8/25 05:00
"Thick" blood can cause heart attack and stroke, but also prevent them. Scientists have explained the mechanism of this clinical paradox for the first time on an animal model. Mice with a greater tendency to form blood clots have larger plaques in their vessels, but they are more stable. Thus, there is less risk that these plaques will rupture and obstruct...
First Measure Of Africa's Coastal Forests: Swampy Mangrove Destruction Threatens Shrimp Farming
- ScienceDaily
- 09/8/25 05:00
Impoverished fishermen along the coast of tropical African countries like Mozambique and Madagascar may have only a few more years to eke out a profit from one of their nations' biggest agricultural exports. Within a few decades, they may no longer have a livelihood at all. That's because swampy mangrove forests – essential breeding grounds for fish and shellfish in these countries – are being...
