A new target for treatment of one type of macular degeneration

Sciencedaily.com 

A new study in mice hints at the promise of an eventual alternative treatment option for the 'wet' version of age-related macular degeneration (AMD). Researchers determined in mice that an enzyme related to cell growth and division is a culprit in the blood vessel invasion in the back of the eye that causes blurred central vision in wet AMD. Targeting the enzyme, called telomerase, with an experimental drug suppressed abnormal vascular growth in the animals' retina.

Study finds health care providers would recommend human papillomavirus self-collection

Sciencedaily.com 

In 2019, more than 12,000 new cases of cervical cancer were diagnosed and upwards of 4,000 patients died in the U.S. The causal link between human papillomavirus (HPV) infection and the development of cervical cancer is well documented. Cervical cancer screening guidelines are currently in the review process for updates.

Implantable microphone could lead to fully internal cochlear implants

Researchers developed a prototype of an implantable microphone for a cochlear implant. Their device, which senses the movement of the ear drum in the inner ear, performed as well as commercial hearing aids and could someday enable a fully internalized cochlear implant.

An ant that selectively amputates the infected limbs of wounded sisters

Sciencedaily.com 

Saving lives through surgery is no longer exclusive to humans. Scientists now detail how Florida carpenter ants, a common, brown species native to its namesake, selectively treat the wounded limbs of fellow nestmates -- either by wound cleaning or amputation. When experimentally testing the effectiveness of these 'treatments,' not only did they aid in recovery, but the research team found the ants' choice of care catered to the type of injury presented to them.

Doctors could soon use facial temperature for early diagnosis of metabolic diseases

Sciencedaily.com 

A colder nose and warmer cheeks may be a telltale sign of rising blood pressure. Researchers discovered that temperatures in different face regions are associated with various chronic illnesses, such as diabetes and high blood pressure. These temperature differences are not easily perceptible by one's own touch but can instead be identified using specific AI-derived spatial temperature patterns that require a thermal camera and a data-trained model. With further research, doctors could one day use... Читать дальше...

Engineered plasma cells show long-lasting antileukemic activity in mice

Sciencedaily.com 

Researchers show for the first time that engineered human plasma B cells can be used to treat a disease -- specifically leukemia -- in a humanized animal model. The results mark a key step in the realization of ePCs as therapies to treat cancer, auto-immune disorders, and protein deficiency disorders.

Proteins and fats can drive insulin production for some, paving way for tailored nutrition

Sciencedaily.com 

When it comes to managing blood sugar levels, most people think about counting carbs. But new research shows that, for some, it may be just as important to consider the proteins and fats in their diet. The study is the first large-scale comparison of how different people produce insulin in response to each of the three macronutrients: carbohydrates (glucose), proteins (amino acids) and fats (fatty acids). The findings reveal that production of the blood sugar-regulating hormone is much more dynamic and individualized than previously thought... Читать дальше...

Melting of Alaskan glaciers accelerating faster than previously thought

Sciencedaily.com 

Melting of glaciers in a major Alaskan icefield has accelerated and could reach an irreversible tipping point earlier than previously thought. The research found that glacier loss on Juneau Icefield, which straddles the boundary between Alaska and British Columbia, Canada, has increased dramatically since 2010. The team looked at records going back to 1770 and identified three distinct periods in how icefield volume changed. In particular, they found that icefield-wide, rates of glacier area shrinkage...

Air conditioning apartheid at Paris Olympic Games

The Washington Times 

Oh, the environmental injustice of it all. Organizers of the Paris Olympic Games thought they were going green by building athletic dormitories without supposedly planet-warming air conditioning.
