Investigating the origins of the crab nebula

Science Daily - 18/06/2024
A team of scientists used NASA's James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus.

IN-SPACe announces pre-incubation programme for aspiring space startups

The Hindu:Science - 17/06/2024
Applicants must be Indian citizens graduating in 2024, or already graduates, they should not have received any grants, funding, or monetary support from private or government schemes, and all submissions must be original work

Year after Titan’s fatal dive, explorers vow to pursue ocean mysteries

The Hindu:Science - 17/06/2024
Numerous ocean explorers are confident undersea exploration can continue safely in a post-Titan world

Indirect evidence builds, yet the ‘dark’ universe remains murky

The Hindu:Science - 17/06/2024
We don’t have direct evidence of dark matter or dark energy but scientists are continuing the search

Gene therapy offers hope for patients with hearing loss

The Hindu:Science - 16/06/2024
It is widely estimated that approximately 50-60% of congenital hearing loss cases are attributed to genetic causes. Among the various populations, genetic variants play a significant role

Some CRISPR screens may be missing cancer drug targets

Science Daily - 15/06/2024
CRISPR/Cas9 gene editing has made possible a multitude of biomedical experiments including studies that systematically turn off genes in cancer cells to look for ones that the cancer cells heavily depend on to survive and grow. These genes, or 'cancer dependencies,' are often promising drug targets. But new research shows that many of these CRISPR screening experiments rely on components, called CRISPR/Cas9 guides, that do not perform equally well in cells from people of all ancestries, which can cause CRISPR screens to miss cancer dependencies.

New study offers a better way to make AI fairer for everyone

Science Daily - 15/06/2024
Researchers show a new way of thinking about the fair impacts of AI decisions.

Gonadal function in male mice disrupted by prenatal risk factors

Science Daily - 15/06/2024
Researchers have consistently shown that prenatal exposure to Di (2-ethyhexyl) phthalate harms the reproductive system in male mice and causes fertility defects. In a new study, scientists have shown that the combination of DEHP and a high-fat diet in pregnant mice can cause more damage to pups than each factor alone.

Scientists solve decades long mystery of NLRC5 sensor function in cell death

Science Daily - 15/06/2024
A new study identifies NLRC5 as an innate immune sensor that plays a crucial role in PANoptotic cell death -- making it a key therapeutic target.

Quantum entanglement measures Earth rotation

Science Daily - 14/06/2024
Researchers carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work represents a significant achievement that pushes the boundaries of rotation sensitivity in entanglement-based sensors, potentially setting the stage for further exploration at the intersection between quantum mechanics and general relativity.

Nano-immunotherapy developed to improve lung cancer treatment

Science Daily - 14/06/2024
Researchers have developed a new nanomedicine therapy that delivers anticancer drugs to lung cancer cells and enhances the immune system's ability to fight cancer. The team showed promising results for the new therapy in cancer cells in the lab and in mouse lung tumor models, with potential applications for improving care and outcomes for patients with tumors that have failed to respond to traditional immunotherapy.

Researchers use large language models to help robots navigate

Science Daily - 14/06/2024
A technique can plan a trajectory for a robot using only language-based inputs. While it can't outperform vision-based approaches, it could be useful in settings that lack visual data to use for training.

Is magnesium the sleeping potion that enables sandhoppers to survive cold winters?

Science Daily - 14/06/2024
A new study has shown for the first time that when sandhoppers want to enter a period of deep sleep each winter they have the means through which to increase the magnesium levels in their bodies -- in some instances more than doubling them. Essentially acting as a natural narcotic, the magnesium puts the sandhopper into a torpid state and this enforced rest means that the creatures can stay hidden in burrows up to 30cm beneath the beach surface, to some extent buffered from wintry conditions.

New metric for blood circulation in brain to better understand dementia

Science Daily - 14/06/2024
Researchers have developed a new metric from measured blood circulation in our brain. This metric has implications for brain conditions, including Alzheimer's disease and other forms of dementia.

New approach to identifying altermagnetic materials

Science Daily - 14/06/2024
An international team has discovered a spectrum characteristic of an altermagnetic material with X-ray magnetic circular dichroism.

High-precision measurements challenge our understanding of Cepheids

Science Daily - 14/06/2024
Scientists have clocked the speed of Cepheid stars -- 'standard candles' that help us measure the size of the universe -- with unprecedented precision, offering exciting new insights about them.
