Wildlife biologists used a novel technique to trace the movement of carbon through Arctic and boreal forest food webs and found that climate warming resulted in a shift from plant-based food webs to fungal-based food webs for several high-latitude species, with potential indirect effects on nutrient cycling and ecosystem function.
Many bacterial pathogens use small injection apparatuses to manipulate the cells of their hosts, such as humans, so that they can spread throughout the body. To do this, they need to fill their syringes with the relevant injection agent. A technique that tracks the individual movement of proteins revealed how bacteria accomplish this challenging task.
Mutations of the tumor suppressor p53 not only have a growth-promoting effect on the cancer cells themselves, but also influence the cells in the tumor's microenvironment. Scientists have now shown that p53-mutated mouse breast cancer cells reprogram fat cells. The manipulated fat cells create an inflammatory microenvironment, impairing the immune response against the tumor and thus promoting cancer growth.
Primate social organization is more flexible than previously assumed. According to a new study, the first primates probably lived in pairs, while only around 15 percent of individuals were solitary.
Research team draws up criteria for PET-based examinations of malignant brain tumors.
We don't know how magnetic fields in the cosmos formed. Now a new theoretical research tells how the invisible part of our universe could help us find out, suggesting a primordial genesis, even within a second of the Big Bang.
A new study to motivate your New Year's resolutions: it demonstrates that high-fat diets negatively impact genes linked not only to obesity, colon cancer and irritable bowels, but also to the immune system and brain function.
A new synthetic antibiotic is shown to be more effective than established drugs against 'superbugs' such as MRSA, a new study shows.
Perovskite nanosheets show distinctive characteristics with significant applications in science and technology. In a recent study, researchers achieved enhanced signal amplification in CsPbBr3 perovskite nanosheets with a unique waveguide pattern, which enhanced both gain and thermal stability. These advancements carry wide-ranging implications for laser, sensor, and solar cell applications, and can potentially influence areas like environmental monitoring, industrial processes, and healthcare.
Acetaminophen is considered the safest over-the-counter pain reliever and fever reducer available during pregnancy. Studies have shown that 50%-65% of women in North America and Europe take acetaminophen during pregnancy. A new study explored the relationship between acetaminophen use during pregnancy and language outcomes in early childhood. It found that increasing acetaminophen use was associated with language delays.
Scientific researchers draw inspiration from nature's brilliance as they seek to develop transformative solutions to unresolved challenges.
For talkative midshipman fish -- sometimes called the 'California singing fish' -- the midbrain plays a robust role in initiating and patterning of sounds used in vocal communication.
Researchers find that microglia --the brain's immune cells -- can trigger cognitive deficits after radiation exposure and may be a key target for preventing these symptoms.
Mount Sinai researchers have shown for the first time that a person's beliefs related to drugs can influence their own brain activity and behavioral responses in a way comparable to the dose-dependent effects of pharmacology.
The temporary, repeated hearing loss caused by chronic ear infections can affect language skills years later.
Coal is an abundant resource in the United States that has, unfortunately, contributed to climate change through its use as a fossil fuel. As the country transitions to other means of energy production, it will be important to consider and reevaluate coal's economic role. Coal may actually play a vital role in next-generation electronic devices.
Researchers have identified a drug target that may alleviate joint degeneration associated with osteoarthritis, a debilitating condition that afflicts as many as 30 million people in the United States alone. Pain relievers and lifestyle changes, such as exercise and reduced excess weight, have long been the therapies most commonly used to treat the joint stiffness and pain caused by degenerative disease, but there is a pressing need for therapies that can prevent joint breakdown that occurs in osteoarthritis.
Researchers have fabricated a new high-performance shortwave infrared (SWIR) image sensor based on non-toxic colloidal quantum dots. They report on a new method for synthesizing functional high-quality non-toxic colloidal quantum dots integrable with complementary metal-oxide-semiconductor (CMOS) technology.
If you have a deep-seated, nagging worry over dropping your phone in molten lava, you're in luck. Materials scientists have developed a method for rapidly discovering a new class of materials with heat and electronic tolerances so rugged that they that could enable devices to function at several thousands of degrees Fahrenheit.
One the missions is a launch of NASA’s Artemis programme, of which India is part
