A bleak outlook for social science?

Experts warn of a bleak outlook for social science due to funding cuts and an 'anti-research' mood in government. However, they also highlight the importance of social sciences in tackling complex challenges and propose solutions to strengthen their involvement in policymaking.

Even oysters pay taxes

A new study proposes that slow-growing animals waste energy in two ways, making too much protein and then discarding excess. Fast-growing oysters, on the other hand, are more efficient at protein production, according to USC marine biologists.

Cat-calls are detrimental to everyone

Women who witness sexism may experience negative emotions and feel motivated to take action against men in general. Research by Chaudoir and Quinn found that catcalls can shape women's feelings and attitudes towards men, with bystander sexism impacting how female observers view all men more negatively.

Bacteria divide like clockwork

Researchers have discovered how cyanobacteria's rate of cell division is regulated by the same circadian clocks that control human sleep patterns. The study found that cells divide once per day at specific points in the 24-hour cycle, with implications for understanding cellular renewal and cancer.

Cultural divide in ability to recognize sensual sounds

A British study found that Westerners reliably recognized six basic human emotions through non-verbal vocalizations, but culturally isolated Himba people only recognized a subset of these emotions. The study highlights the importance of considering positive emotions in cross-cultural research.

Patient referrals cause differences in hospital infection rates

A study published in PLOS Computational Biology found that patient referrals between hospitals influence the rates of hospital-acquired infections, with University Medical Centers showing higher rates. The authors suggest focusing interventions on central hospitals in the network of patient referrals.

Nano-based RFID tags could replace bar codes

Rice researchers have developed an inexpensive, printable transmitter for RFID tags that can be invisibly embedded in packaging. This technology has the potential to revolutionize checkout processes by allowing customers to walk through a scanner with their groceries without stopping at each item.

Women do make men throw caution to the wind, research confirms

A study in Social Psychological and Personality Science found that young men took greater physical risks and had higher testosterone levels when attempting tricks in front of an attractive female. This suggests that the presence of a beautiful woman can lead to increased risk-taking behavior and elevated testosterone levels in men.

Medicare patients 5.5 times more likely to get cataract surgery than VA patients, study finds

A large eight-year study found that Medicare patients are 5.5 times more likely to undergo routine cataract surgery than those receiving care from the Department of Veterans Affairs. The disparity may be attributed to financial incentives, physician-driven decisions, or a lack of ophthalmologists within the VA system.

France's national program to reduce HAIs reports important successes; uses mandatory reporting

A French national program to reduce healthcare-associated infections (HAIs) reported important successes with mandatory public reporting. The program led to a drop of 40% in MRSA cases and improved infection control measures across the country. Key initiatives included advancing research, improving communication with patients, and stan...

Getting turned on

A molecule called Rab35 acts as a switch to activate the fast-track recycling pathway, allowing cargo to be rapidly selected and transported. Defects in this trafficking pathway can lead to numerous diseases, including high cholesterol and neuropathies.

Study shows strong interest in palliative care programs, services and integration vary across nation

A study by University of Texas M.D. Anderson Cancer Center reveals that US cancer centers have varying levels of palliative care programs and services, with NCI-designated centers having more comprehensive programs. Despite the differences, there is strong support for integrating palliative care into oncology care.

First temperate exoplanet sized up

Astronomers have discovered a temperate exoplanet, Corot-9b, with a mass about 80% that of Jupiter and an orbit similar to Mercury's. The planet is thought to have a temperature range of -20°C to 160°C, making it a significant finding in the study of exoplanets.

LSUHSC research increases understanding of drug metabolism

Research by LSU Health Sciences Center scientists has found that drug metabolism is influenced by the interaction between enzymes, which can affect a drug's elimination from the body or conversion into toxic byproducts. The study suggests that testing individual enzymes alone may not be sufficient to predict drug effectiveness and safety.

Efforts to steer patients to lower-cost physicians may be based on misleading rankings, study finds

A new study by RAND Corporation found that about one-fourth of physicians would be misclassified under cost ranking systems, raising questions about their utility for high-stakes activities like tiered health plans. Only about 40% of physicians had cost profile scores at least 70% reliable, and fewer than 10% were at least 90% reliable.
