Molecules boosting plant immunity identified
- ScienceDaily
- 22/7/7 23:19
Researchers have discovered natural cellular molecules that drive critical plant immune responses. These compounds have all the hallmarks of being small messengers tailored by plants to turn on key defense-control hubs. Harnessing these insights may allow scientists and plant breeders to design molecules that make plants, including many important crop species, more resistant to disease.
Carbon conservation efforts would be enhanced by highlighting threatened forest primates

Citizen scientist leads discovery of 34 ultracool dwarf binaries
- ScienceDaily
- 22/7/7 23:18
How often do stars live alone? For brown dwarfs -- objects that straddle the boundary between the most massive planets and the smallest stars -- astronomers need to uncover more examples of their companions to find out. Ace citizen scientists have done just that by using the Astro Data Lab science platform at NSF's NOIRLab to discover 34 new ultracool dwarf binary systems in the Sun's...

- 22/7/7 23:18
Researchers found that high dose nitric oxide given to pregnant women with severe COVID-19 pneumonia resulted in reductions in the need for supplemental oxygen as well as in hospital and ICU lengths of stay, with no adverse events reported in mothers or newborns.
How sound reduces pain in mice

Scientists have identified the neural mechanisms through which sound blunts pain in mice. The findings could inform development of safer methods to treat pain.
New insights about surface, structure of asteroid Bennu
- ScienceDaily
- 22/7/7 20:24
When NASA's OSIRIS-REx spacecraft collected samples from asteroid Bennu's surface in 2020, forces measured during the interaction provided scientists with a direct test of the poorly understood near-subsurface physical properties of rubble-pile asteroids. Now, a new study has characterized the layer just below the asteroid's surface as composed of weakly bound rock fragments containing twice the...
Familiarity breeds exempt: Why staph vaccines don't work in humans
- ScienceDaily
- 22/7/7 20:23
Researchers say they may have found the reason why multiple human clinical trials of staphylococcus vaccines have failed: the bacteria knows us too well.
New research finds deep-sea mining noise pollution will stretch hundreds of miles
- ScienceDaily
- 22/7/7 20:21
New research examines the potential for underwater noise pollution from seabed mining operations, which could affect the understudied species that live in the deep sea -- the largest habitat on Earth.
Toads surprise scientists by climbing trees in UK woodlands
- ScienceDaily
- 22/7/7 20:21
Volunteers surveying dormice and bats in trees have made the unexpected discovery of over fifty common toads in nest boxes and tree cavities at least 1.5 meters high.
Gestures can improve understanding in language disorders
- ScienceDaily
- 22/7/7 20:19
When words fail, gestures can help to get the message across -- especially for people who have a language disorder. An international research team has now shown that listeners attend the gestures of people with aphasia more often and for much longer than previously thought. This has implications for the use of gestures in speech therapy.
Rising tide in adverse drug reactions
- ScienceDaily

Researchers have identified an increasing trend in medicine-related harm leading to hospital admission.
Parkinson's disease: Copper leads to protein aggregation, study finds
- ScienceDaily
- 22/7/7 20:19
Copper exposure in the environment and the protein alpha-synuclein in the human brain could play an important role in the pathogenesis of Parkinson's disease. Researchers were able to show how the protein takes on an unusual shape when exposed to large amounts of copper ions. The findings could help develop new strategies for the treatment of neurodegenerative diseases.
Electric vehicle buyers want rebates, not tax credits
- ScienceDaily
- 22/7/7 20:19
Financial incentives play an important role in the widespread adoption of electric vehicles. New research, however, finds that not all financial incentives are created equal in the eyes of prospective car buyers, and the current federal incentive -- a tax credit -- is, in fact, valued the least by car buyers.
Nanoparticle 'backpacks' restore damaged stem cells
- ScienceDaily
- 22/7/7 20:18
Bioengineers have shown that a new strategy can restore damaged stem cells and enable them to grow new tissues again. The new drug delivery system could help infants born from complicated pregnancies.
Experts predict top emerging impacts on ocean biodiversity over next decade
- ScienceDaily
- 22/7/7 20:18
Lithium extraction from the deep sea, overfishing of deeper-water species, and the unexpected ocean impacts of wildfires on land are among fifteen issues experts warn we ought to be addressing now.
Scientists use mini-kidney models to identify potential drugs for polycystic kidney disease
- ScienceDaily
- 22/7/7 20:18
Scientists hsve generated simple kidney-like structures called organoids and used them to identify potential drugs to treat adult-onset polycystic kidney disease. To accelerate the quest for new treatments for ADPKD, researchers used pluripotent stem cells to grow organoids consisting of one or two structures resembling the kidney's filtering units, known as nephrons. To make the organoids useful...
150 southern fin whales observed feeding together
- ScienceDaily
- 22/7/7 20:18
After blue whales, fin whales are the largest whales in the world -- and human beings have hunted both species to near-extinction. After the ban on commercial whaling in 1976, the stocks of these long-lived, but slow-growing creatures are rebounding: researchers have witnessed large groups of up to 150 southern fin whales in their historical feeding areas -- more than has ever been documented...

The beginning of life: The early embryo is in the driver's seat
- ScienceDaily
- 22/7/7 20:18
One often thinks that the early embryo is fragile and needs support. However, at the earliest stages of development, it has the power to feed the future placenta and instructs the uterus so that it can nest. Using 'blastoids', in vitro embryo models formed with stem cells, scientists have shown that the earliest molecular signals that induce placental development and prepare the uterus come from...
