Arsenic may raise diabetes risk for males

Science Daily - 09/01/2024
Chronic exposure to arsenic, often through contaminated groundwater, has been associated with Type 2 diabetes in humans, and there are new clues that males may be more susceptible to the disease when exposed.

Rallying for a better badminton birdie

Science Daily - 09/01/2024
Shuttlecocks, also known as birdies or birds, are traditionally made from duck feathers, but nylon shuttlecocks have become more widely used because of their superior durability. Their flight behavior, however, is far different from that of traditional feather birdies. Scientists have now explored the aerodynamic performance of nylon shuttlecocks at various flight speeds. Through computational analyses based on two-way fluid-structure interactions, the team coupled equations governing air flow with equations determining skirt deformation of a shuttlecock in flight.

The hidden identity of leukemia

Science Daily - 09/01/2024
Researchers used various sequencing technologies to explore the molecular characteristics of myeloid/natural killer cell precursor acute leukemia (MNKPL). They observed activation of the NOTCH1 and RUNX3 genes, with lower expression of the BCL11B gene. MNKPL cells were also highly sensitive to a drug called L-asparaginase. Collectively, these qualities make MNKPL distinct from other leukemia types. These insights will assist with more accurate clinical diagnoses and therapeutic development for MNKPL.

Light measurement enables estimation of the chemical attributes of spice extracts

Science Daily - 09/01/2024
Researchers have developed a nondestructive method utilizing light to estimate the total amount of polyphenols and flavonoids in spice extracts, along with their antioxidant and reducing capacities. By comprehensively capturing the autofluorescence emitted by components, such as polyphenols and flavonoids, they have demonstrated the precise evaluation of chemical constituents using the application of machine learning methods.

With Aditya-L1 spacecraft placed in halo orbit, focus is on data collection on sun  

The Hindu:Science - 09/01/2024
The payloads have been switched on and some of them have already collected data

U.S. moon landing attempt seems doomed after fuel leak 

The Hindu:Science - 09/01/2024
Astrobotic’s apparent failure could complicate the U.S.’s strategy to ship hardware to the moon using the commercial sector

Love scrambles the brain and scientists can now tell us why

Science Daily - 09/01/2024
Love is blind, the saying goes, and thanks to a new study we are now a step closer to understanding why. Researchers have measured how a part of the brain is responsible for putting our loved one on a pedestal in that first flush of romance.

Spanish butterflies better at regulating their body temperature than their British cousins

Science Daily - 09/01/2024
Butterfly populations in Catalonia in northern Spain are better than their UK counterparts at regulating their body temperature by basking in the sunshine, but rising global temperatures due to climate change may put Spanish butterflies at greater risk of extinction.

NASA to push back moon mission timelines amid spacecraft delays - sources

The Hindu:Science - 09/01/2024
NASA is set to delay its next few missions to the moon under a key program as technical hurdles mount with the various spacecraft it intends to use to get there, according to four people familiar with NASA’s plans.

Coastal populations set to age sharply in the face of climate migration

Science Daily - 09/01/2024
As climate change fuels sea level rise, younger people will migrate inland, leaving aging coastal populations -- and a host of consequences -- in their wake, a study finds. While destination cities will work to sustainably accommodate swelling populations, aging coastal communities will confront stark new challenges, including an outflow of vital human infrastructure such as health care workers.

Measuring grass pollen allergens instead of grass pollen count will help hay fever sufferers

Science Daily - 09/01/2024
Measuring airborne grass allergen levels instead of pollen counts will be more beneficial for hay fever sufferers as new research shows grass allergen levels are more consistently associated with hay fever symptoms than grass pollen counts.

Clear link between autoimmune disease and perinatal depression

Science Daily - 09/01/2024
Women with autoimmune disease are more likely to suffer from depression during pregnancy and after childbirth; conversely, women with a history of perinatal depression are at higher risk of developing autoimmune disease, a new study reports.

Scientists give new insight into a molecular target of alcohol

Science Daily - 09/01/2024
By investigating a molecule in the brain tied to cellular communication, scientists uncover important information about the proteins that do -- and do not -- influence alcohol drinking behavior.

COVID-19 vaccine strongly effective for children and adolescents during delta and omicron, real-world analysis shows

Science Daily - 09/01/2024
In a real-world setting, analysis showed that risk of infection and severe illness was significantly lower for those who were vaccinated against COVID-19, and cardiac conditions did not increase.

Final supernova results from Dark Energy Survey offer unique insights into the expansion of the universe

Science Daily - 09/01/2024
In the culmination of a decade's worth of effort, scientists analyzed an unprecedented sample of more than 1,500 supernovae classified using machine learning. They placed the strongest constraints on the expansion of the universe ever obtained with the DES supernova survey. While consistent with the current standard cosmological model, the results do not rule out a more complex theory that the density of dark energy in the universe could have varied over time.

Life span increases in mice when specific brain cells are activated

Science Daily - 09/01/2024
A new study identifies, in mice, a critical communication pathway connecting the brain and the body's fat tissue in a feedback loop that appears central to energy production throughout the body. The research suggests that the gradual deterioration of this feedback loop contributes to the increasing health problems that are typical of natural aging.

Solid state battery design charges in minutes, lasts for thousands of cycles

Science Daily - 09/01/2024
Researchers have developed a new lithium metal battery that can be charged and discharged at least 6,000 times -- more than any other pouch battery cell -- and can be recharged in a matter of minutes. The research not only describes a new way to make solid state batteries with a lithium metal anode but also offers new understanding into the materials used for these potentially revolutionary batteries.

How did the bushpig cross the strait? A great puzzle in African mammal biogeography solved by genomics

Science Daily - 09/01/2024
Africa has a huge diversity of large mammals, but their evolutionary relationships and movement across the continent over time often remain a mystery. A new scientific study sheds light on longstanding questions about the interplay between evolution and geography in one of these mammals, namely the iconic African bushpig, and helps settle a major question regarding prehistoric human activities shaping biodiversity patterns in Africa.

New soft robots roll like tires, spin like tops and orbit like moons

Science Daily - 09/01/2024
Researchers have developed a new soft robot design that engages in three simultaneous behaviors: rolling forward, spinning like a record, and following a path that orbits around a central point. The device, which operates without human or computer control, holds promise for developing soft robotic devices that can be used to navigate and map unknown environments.
