Rice physicists kill cancer with 'nanobubbles'

Scientists at Rice University have discovered a new technique for singling out individual diseased cells and destroying them with tiny explosions using lasers and nanoparticles. The method, known as nanobubbles, can be tuned to create either small, harmless bubbles or large bubbles that burst the cells.

Prion leaves lasting mark on memory

A new report reveals that a prion-like protein called CPEB may participate in memory in higher eukaryotes, including sea slugs. The protein's ability to switch between distinct conformational states suggests it could maintain stable states with unstable biological molecules.

Winning the war on weight

A Monash University-led nationwide study found that severely obese individuals feel powerless to change their weight due to internalized stigma and shame. In contrast, mildly to moderately obese individuals believed they could lose weight if needed, but felt no urgent need to do so.

Bacteria toxic to wound-treating maggots

Researchers found that maggot 'biosurgeons' used to treat chronic wounds are vulnerable to deadly bacteria Pseudomonas aeruginosa, which can kill the maggots within 20 hours. This discovery could lead to more effective treatment of wounds and development of novel antibiotics.

New study finds possible source of beta cell destruction that leads to type 1 diabetes

A new study published by researchers at Eastern Virginia Medical School has identified a protein-based enzyme called 12-Lipoxygenase (12-LO) as a key player in the development of Type 1 diabetes. The enzyme produces specific lipids that cause inflammation and lead to beta cell death, highlighting a potential target for new therapies.

Research finds water movements can shape fish evolution

Researchers from the University of Minnesota have found that fish bodies and swimming styles evolve to optimize efficiency in their respective aquatic environments. Computational simulations revealed that fish adapt their forms and techniques to match their speeds, demonstrating the influence of water movements on fish evolution.

Ancient remains put teeth into Barker hypothesis

The study found that tooth enamel defects in ancient humans were associated with shortened lifespans, suggesting a link between early life stress and adult diseases. The research supports the Barker hypothesis, which proposes that many adult diseases originate during fetal development and early childhood.

Aiming to the side

Researchers at the Weizmann Institute of Science found that bats aim their sound beams off-center when locating objects, making this strategy more efficient than aiming directly at the center. This approach allows bats to better track movement across the beam.

Promising results shown for kidney cancer drug

A new study published in Journal of Clinical Oncology found that pazopanib slowed the progression of advanced renal cell carcinoma, a form of kidney cancer, in patients by 54%. The drug targets multiple pathways within cancer cells, inhibiting blood vessel development. Common side effects include diarrhea, hypertension, and weight loss.

'Zen' bats hit their target by not aiming at it

A new study reveals that Egyptian fruit bats use an alternative strategy to detect and track targets. By alternating the direction of their sonar beam, they can pinpoint the location of a target but make it harder to detect in the first place. This approach optimizes pinpoint accuracy while sacrificing some detection ability.

Pitt-led team gets $5.6 million contract for heart assist device for infants and toddlers

Researchers at the University of Pittsburgh are developing a heart assist device called PediaFlow to support infants and small children with congenital or acquired heart disease. The device has already shown promise in preclinical research, pulling oxygenated blood from the left ventricle through its innovative mag-lev technology.

York study maps the effects of acupuncture on the brain

A new study by the University of York reveals that acupuncture significantly affects specific neural structures in the brain, particularly those associated with pain processing. This finding could lead to a better understanding of how acupuncture works and its potential as a treatment option for various medical conditions.
