A single genetic test could potentially replace the current two-step approach to diagnosing rare developmental disorders in children. This shift could enable earlier diagnoses for families and save vital resources.
Neuroscientists have established in recent decades the idea that some of each day's experiences are converted by the brain into permanent memories during sleep the same night. Now, a new study proposes a mechanism that determines which memories are tagged as important enough to linger in the brain until sleep makes them permanent.
A group of international experts has presented a blueprint for national indoor quality standards for public buildings. The experts addressed setting standards for three key indoor pollutants -- carbon dioxide, carbon monoxide, and PM2.5 (particles so small they can lodge deep in the lungs and enter the bloodstream) -- and ventilation rate.
Vaccination not only reduces the severity of TB in infected cattle, but reduces its spread in dairy herds by 89%, research finds.
SARS-CoV-2 will eventually become resistant to the only effective oral treatment. The world needs another, say researchers.
A new bioluminescence imaging technique has created highly detailed, and visually striking, images of the movement of oxygen in the brains of mice. The method, which can be easily replicated by other labs, will enable researchers to more precisely study forms of hypoxia in the brain, such as the denial of oxygen to the brain that occurs during a stroke or heart attack. The new research tool is already providing insight into why a sedentary lifestyle may increase risk for diseases like Alzheimer's.
Women affected by premenstrual disorders have a higher risk of perinatal depression compared with those who do not, according to new research. The relationship works both ways: those with perinatal depression are also more likely to develop premenstrual disorders after pregnancy and childbirth. This study suggests that a common mechanism might contribute to the two conditions.
Analysing the diversity of organic compounds dissolved in freshwater provides a reliable measure of ecosystem health, say scientists.
Biologists have uncovered a quality control timing mechanism tied to cell division. The 'stopwatch' function keeps track of mitosis and acts as a protective measure when the process takes too long, preventing the formation of cancerous cells.
Hyenas are generalist predators (and scavengers) with a broad range of prey species. They are known for hunting (or scavenging) larger mammals such as antelopes and occasionally feed on smaller mammals and reptiles. Being flexible in the choice of prey is a strategy of generalists -- and this even extends to small passerine birds, as scientists observed in Namibia: Spotted hyenas pursued red-billed queleas, picked them from the ground or the surface of a waterhole and swallowed them whole, at a success rate of approximately one bird every three minutes.
To woo a mate, the Albert's Lyrebird of Australia becomes a real song-and-dance bird. Each male first chooses a stage of entangled vines, then in performance he shakes the vines as part of his courtship footwork, synchronizing each shake with the beat of his striking song.
A stroke often impacts a person's ability to move their lower body from the hips down to the feet. This leads to diminished quality of life and mental health in addition to increased susceptibility to falls. But now, researchers are exploring new treatment methods to help bridge the service delivery gap, and recovery outcomes, for patients after a stroke.
The Union Public Service Commission (UPSC) has released the results for the Engineering Services Examination (ESE) Preliminary 2024 on March 28, 2024. Candidates who qualified will proceed to the Main Examination scheduled for June 23, 2024. The results are provisional, subject to meeting eligibility criteria outlined by the Ministry of Communications and the Commission's guidelines. E-Admit Cards for the Main Examination can be downloaded from the UPSC website, and further details will be provided post-examination.
The Bihar School Examination Board is gearing up to announce the Bihar Board 10th Matric Result 2024 shortly, which will be available for download on the official website biharboardonline.bihar.gov.in. The exams were conducted from February 15 to February 23, 2024, with approximately 16.4 lakh students participating across 1,548 exam centers and two sessions.
New research shows that trying to stifle boredom at work prolongs its effects and that alternating boring and meaningful tasks helps to prevent the effects of one boring task from spilling over to reduce productivity on others.
What did an ancient Chinese emperor from 1,500 years ago look like? A team of researchers reconstructed the face of Chinese Emperor Wu of Northern Zhou using DNA extracted from his remains. The study suggests the emperor's death at the age of 36 might be linked to a stroke. It also sheds light on the origin and migration patterns of a nomadic empire that once ruled parts of northeastern Asia.
New DNA sequencing technologies have identified the historical remains of George Washington's grandnephews, Samuel Walter Washington and George Steptoe Washington Jr., and their mother, Lucy Payne Washington, from unmarked, fragmentary bones left at the Harewood family cemetery in Charles Town, West Virginia, in the mid-1800s.
Familial Alzheimer's disease can be transferred via bone marrow transplant, researchers show. When the team transplanted bone marrow stem cells from mice carrying a hereditary version of Alzheimer's disease into normal lab mice, the recipients developed Alzheimer's disease -- and at an accelerated rate.
Generative artificial intelligence (AI) might be best known from text or image-creating applications like ChatGPT or Stable Diffusion. But its usefulness beyond that is being shown in more and more different scientific fields.
Younger women are generally thought to have a low risk of heart disease, but new research urges clinicians to revisit that assumption, especially for women who suffer from certain mental health conditions. A new study found that having anxiety or depression could accelerate the development of cardiovascular risk factors among young and middle-aged women.
