UrduHow are you sleeping? A new study has found the transition from daylight saving time to standard time, when one hour is gained overnight, was associated with a brief increase in sleep disorders such as difficulty going to sleep or staying asleep, but there was no such association when an hour is lost in the change from standard time to daylight saving time. The study is published in the May 3, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. It also found a small difference in the amount of sleep people get depending on the season.

Moffitt Researchers Develop CAR T Cells that Fight Prostate Cancer in Bone
Prostate cancer frequently metastasizes to the bone and is incurable. Moffitt Cancer Center researchers are working to identify new treatment options for this subset of patients. In a new article published today in Science Advances, a team of Moffitt scientists demonstrates that chimeric antigen receptor T-cell (CAR T) therapy is an effective antitumor approach in mouse models of bone metastatic prostate cancer.
Conformer-Dependent Reactivity of Carbonyl Oxides Leads to Dramatically Different Atmospheric Fates
The air pollutant secondary organic aerosol (SOA) forms when ammonia and amines react with oxygenated species. When ammonia is present when alkenes react with ozone, SOA increases in size and numbers. This may be due to Criegee intermediates. New research found that a particular amine, dimethylamine, reacts 34,000 times faster with one version of the Criegee intermediate acetaldehyde oxide than with another version of the same compound.

New ACR Breast Cancer Screening Guidelines call for earlier and more-intensive screening for high-risk women
New ACR breast cancer screening guidelines urge all women, particularly Black and Ashkenazi Jewish women, to have a risk assessment by age 25 to determine if screening before age 40 is needed. The ACR urges average-risk women to start yearly screening at 40, but earlier screening for high-risk women.
How Does Glucocorticoid Therapy Affect the Developing Cardiovascular System During Pregnancy?
Glucocorticoid therapy is widely used during pregnancies at risk of premature delivery to promote fetal lung maturation. While it is an effective treatment, it can also trigger heart and blood vessel problems. New research published in The FASEB Journal uncovers the mechanisms behind the cardiovascular-related effects of the most commonly used glucocorticoids, Dexamethasone (Dex) and Betamethasone (Beta).

Researchers capture elusive missing step in the final act of photosynthesis
Photosynthesis plays a crucial role in shaping and sustaining life on Earth, yet many aspects of the process remain a mystery. One such mystery is how Photosystem II, a protein complex in plants, algae and cyanobacteria, harvests energy from sunlight and uses it to split water, producing the oxygen we breathe. Now researchers from the Department of Energy’s Lawrence Berkeley National Laboratory and SLAC National Accelerator Laboratory, together with collaborators from Uppsala University and Humboldt University and other institutions have succeeded in cracking a key secret of Photosystem II.

Astronomers Witness Star Devouring Planet: Possible Preview of the Ultimate Fate of Earth
Astronomers using the Gemini South telescope in Chile, operated by NSF’s NOIRLab, have observed the first evidence of a dying Sun-like star engulfing an exoplanet. The “smoking gun” of this event was seen in a long and low-energy outburst from the star — the telltale signature of a planet skimming along a star’s surface. This never-before-seen process may herald the ultimate fate of Earth when our own Sun nears the end of its life in about five billion years.
Por primera vez astrónomos observan un planeta devorado por su estrella
Un equipo de astrónomos registró la primera evidencia de una estrella moribunda, similar al Sol, devorando un exoplaneta, gracias a observaciones realizadas con el telescopio de Gemini Sur en Chile, que opera NOIRLab de NSF y Observatorio AURA. La evidencia irrefutable de este evento quedó registrada en un estallido largo y de baja energía de la estrella, un signo revelador de un planeta rozando la superficie de un Sol distante. Este proceso nunca visto antes puede indicar cómo será el destino final de la Tierra cuando nuestro propio Sol alcance el final de su vida en unos 5 mil millones de años más.

Fossil find in California shakes up the natural history of cycad plants
Cycads, a group of gymnosperms which can resemble miniature palm trees (like the popular sago palm houseplant) were long thought to be “living fossils,” a group that had evolved minimally since the time of the dinosaurs. Now, a well-preserved 80-million-year-old pollen cone discovered in California has rewritten scientific understanding of the plants.

Study identifies a new potential target for treating vascular disease
In a novel study in The American Journal of Pathology, published by Elsevier, researchers found that when fragile-X related protein-1 (FXR1) is absent, VSMC proliferate more slowly, become senescent, and scar tissue (neointima) development is reduced. Therefore, drugs targeting FXR1 may treat vascular proliferative diseases.
