Researchers have discovered how antibodies help to protect against contagious bacterial infections caused by Strep A, including strep throat. And the findings are already contributing to efforts to accelerate the development of a Strep A vaccine.
Plants struggled for millions of years after the world's worst climate catastrophe (link is external)
Scientists have uncovered how plants responded to catastrophic climate changes 250 million years ago. Their findings reveal the long, drawn-out process of ecosystem recovery following one of the most extreme periods of warming in Earth's history: the 'End-Permian Event'.
Tracking polar bears during their most secretive stage of life (link is external)
Researchers have combined satellite collar data with specialized cameras to shed light on one of the most mysterious and important stages in polar bears' lives -- maternal denning, when bears give birth then emerge with their cubs.
The chances of anything coming from Mars (link is external)
Within the next decade, space agencies plan to bring samples of rock from Mars to Earth for study. Of concern is the possibility these samples contain life, which could have unforeseen consequences. Therefore, researchers in this field strive to create methods to detect life. Researchers have now successfully demonstrated a method to detect life in ancient rocks analogous to those found on Mars.
Throat microbiome holds clues to older Australians' health (link is external)
New research has uncovered a potential marker that could provide valuable insights into the overall health of older adults living in long-term aged care facilities. The study found that a simple swab from the back of the throat, known as the oropharynx, may offer clues about health challenges faced by aged care residents.
Flooding expected sooner in Hawai'i's sinking coastal areas (link is external)
Some parts of Hawai'i are sinking faster than others. That discovery also highlights that as sea level rises, the infrastructure, businesses, and communities in these low-lying areas are at risk of flooding sooner than scientists anticipated, particularly in certain urban areas of O'ahu.
The yucca and the moth: How extreme weather impacts the timing of biological events (link is external)
A study sheds light on how extreme weather events impact phenological processes, specifically the flight period of butterflies and moths and the flowering time of plants, with implications for food security in the wake of climate change.
New STI impacts 1 in 3 women: Landmark study reveals men are the missing link (link is external)
A landmark study reveals that bacterial vaginosis (BV), a condition affecting nearly a third of women worldwide and causing infertility, premature births and newborn deaths, is in fact an STI, paving the way for a revolution in how it is treated.
Seismic study of Singapore could guide urban construction and renewable energy development (link is external)
A new seismic study of Singapore could guide urban growth and renewable energy development in the coastal city nation, where 5.6 million residents live within an area of 734 square kilometers.
Insect populations are declining -- and that is not a good thing (link is external)
Using two species of flies from different climates -- one from the cool, high-altitude forests of Northern California, the other hailing from the hot, dry deserts of the Southwest -- scientists discovered remarkable differences in the way each processes external temperature.
Packets of freeze-dried bacteria grow biocement on demand (link is external)
Cement manufacturing and repair could be significantly improved by using biocement-producing bacteria, but growing the microbes at construction sites remains a challenge. Now, researchers report a freeze-drying approach that preserves the bacteria, potentially allowing construction workers to ultimately use powder out of a packet to quickly make tiles, repair oil wells or strengthen the ground for makeshift roads or camps.
Researchers use a 'Trojan Horse' approach to develop new antimalarial drugs (link is external)
Antimalarial drug resistance is a pressing issue in combating the spread of malaria worldwide. In a new study, researchers discovered a key process where malarial parasites take up a human blood cell enzyme, which could provide a new approach for antimalarial treatment.
Caribou migration patterns are shrinking (link is external)
The study shows caribou herds changed their migratory duration, distance or elevation over 35 years of radio tag tracking.
Damaged but not defeated: Bacteria use nano-spearguns to retaliate against attacks (link is external)
Some bacteria deploy tiny spearguns to retaliate against rival attacks. Researchers mimicked attacks by poking bacteria with an ultra-sharp tip. Using this approach, they have uncovered that bacteria assemble their nanoweapons in response to cell envelope damage and rapidly strike back with high precision.
New antibodies show potential to defeat all SARS-CoV-2 variants (link is external)
A team has found two antibodies that can work together to neutralize the virus that causes COVID-19 in all its current known variations in a laboratory environment. More research is needed, but the approach shows promise in developing treatments to keep pace with evolving viruses.
Research identifies key antibodies for development of broadly protective norovirus vaccine (link is external)
Scientists have discovered a strategy to fight back against norovirus, a leading cause of gastroenteritis worldwide. Their new study identifies powerful antibodies capable of neutralizing a wide range of norovirus strains. The finding could lead to the design of broadly effective norovirus vaccine, as well as the development of new therapeutic antibodies for the treatment of norovirus-associated gastroenteritis.
Researchers quantify the way rivers bend, opening up the possibility for identifying origins of channels on other planets (link is external)
Whether it's rivers cutting through earth, lava melting through rock, or water slicing through ice, channels all twist and bend in a seemingly similar back-and-forth manner. But a new study has discovered that channels carved by rivers actually have curves distinct to those cut by lava or ice.
Iconic Australian bird reveals hidden farming talent (link is external)
The beloved Australian lyrebird best known for its stunning tail and powers of mimicry may have a cunning hidden talent.
Aluminum: A new hero of hydrogen production (link is external)
Engineers have developed a method to utilize aluminum to improve performance of water electrolysis catalyst.
A sustainable iron catalyst for water oxidation in renewable energy (link is external)
A newly developed pentanuclear iron complex can offer an efficient, stable, and cost-effective solution for water oxidation. By electrochemically polymerizing the complex, researchers have obtained a polymer-based catalyst, poly-Fe5-PCz, and achieved water oxidation with up to 99% Faradaic efficiency and exceptional stability, even under rigorous conditions. This breakthrough offers a scalable alternative to rare metal catalysts, advancing hydrogen production and energy storage for renewable energy.
