Wasps that recognize faces cooperate more, may be smarter

08/12/2023
A new study of paper wasps suggests social interactions may make animals smarter. The research offers behavioral evidence of an evolutionary link between the ability to recognize individuals and social cooperation.

Very early treatment of newborns with HIV could result in medication-free remission for many babies

08/12/2023
An unexpectedly high percentage of children, who were born with HIV and started treatment within 48 hours of life, exhibit biomarkers by 2 years of age that may make them eligible to test for medication-free remission, according to a multinational study.

Sister climate cities, utility data predict future water, electricity demands

08/12/2023
Modern-day Ciudad Mante, Mexico, could help Tampa, Florida, plan for shifting water and electricity demands due to climate change, according to an international team of researchers. Researchers used utilities data and climate analogs -- contemporary cities with climates close to what other cities are predicted to experience in the future -- to assess how climate change may impact residential water and electricity use across 46 cities in the United States.

It turns out, this fossil 'plant' is really a fossil baby turtle

08/12/2023
Researchers re-examined a plant fossil found decades ago in Colombia and realized that it wasn't a plant at all: it's a fossilized baby turtle. It's a rare find, because juvenile turtles' shells are soft and often don't fossilize well.

Novel and promising pancreatic cancer organoids for effective screening of anticancer drugs

08/12/2023
The treatment of pancreatic cancer, an aggressive form of cancer associated with high mortality rates, is challenging owing to limited options and anticancer screening models. High mortality has been attributed to the unique tumor microenvironment (TME). Researchers have now created a pancreatic ductal adenocarcinoma (PDAC) organoid model using human-induced pluripotent stem cell (hiPSC) technology, simulating desirable TME properties. Their research findings have far-reaching consequences in the field of cancer biology.

Protein found in brain linked to frontotemporal dementia

08/12/2023
An international team of researchers has identified a protein found in the brains of people with frontotemporal dementia (FTD), discovering a new target for potential treatments for the disease.

Geoscientists map changes in atmospheric CO2 over past 66 million years

08/12/2023
An international consortium of geoscientists has reconstructed atmosphereric levels of CO2 going back 66 million years using proxies in the geoloogical record. Today's concenteration, 420 parts per million, is higher than it's ever been in 14 million years.

Ancient stars made extraordinarily heavy elements

08/12/2023
How heavy can an element be? An international team of researchers has found that ancient stars were capable of producing elements with atomic masses greater than 260, heavier than any element on the periodic table found naturally on Earth. The finding deepens our understanding of element formation in stars.

Soundwaves harden 3D-printed treatments in deep tissues

08/12/2023
Engineers have developed a bio-compatible ink that solidifies into different 3D shapes and structures by absorbing ultrasound waves. Because the material responds to sound waves rather than light, the ink can be used in deep tissues for biomedical purposes ranging from bone healing to heart valve repair.

Wild birds lead people to honey -- and learn from them

08/12/2023
A study finds the greater honeyguide can learn distinct vocal signals to help people in Africa locate bee colonies. In parts of Africa, people communicate with a wild bird -- the greater honeyguide -- in order to locate bee colonies and harvest their stores of honey and beeswax. It's a rare example of cooperation between humans and wild animals, and a potential instance of cultural coevolution.

New method is better able to map immune response and paves way for new treatments

08/12/2023
A new method can identify unique immune cell receptors and their location in tissue, a new study reports. The researchers predict that the method will improve the ability to identify which immune cells contribute to disease processes and open up opportunities to develop novel therapies for numerous diseases.

Catalyst for electronically controlled C--H functionalization

08/12/2023
Scientists chipping away at one of the great challenges of metal-catalyzed C--H functionalization with a new method that uses a cobalt catalyst to differentiate between bonds in fluoroarenes, functionalizing them based on their intrinsic electronic properties. And their method is fast -- comparable in speed to those that rely on iridium.

New target found for treatment of spinal muscular atrophy

08/12/2023
Medical researchers have uncovered a novel mechanism that leads to motor neuron degeneration in spinal muscular atrophy (SMA). This discovery offers a new target for treatment that overcomes important limitations of gene therapy and other current therapies for SMA.
