Geckos, cockroaches, and robots dive off ledge, swing under to safety

Researchers have identified and characterized a new behavior in geckos and cockroaches, allowing them to run off ledges and execute a pendulum-like motion to swing underneath. This discovery has inspired the development of robots that can also perform this acrobatic move, with potential applications in search-and-rescue missions.

Stealing life's building blocks

Researchers found that parasitic flowers share large parts of their genome with host vines through horizontal gene transfer, and some borrowed genes are likely functional. The process may convey an evolutionary advantage to the flowers, which have replaced vertically inherited copies.

Baby's genome deciphered prenatally from parents' lab tests

Researchers successfully sequenced the fetal genome without invasive sampling, enabling the detection of thousands of disorders. They overcame obstacles by applying statistical modeling and technical advances to resolve maternal haplotypes with high accuracy. The breakthrough paves the way for comprehensive prenatal genetic screening.

Appalachian infant death rates point to healthcare deficit

Infant mortality rates remain high in Appalachia, with white infants facing disproportionately higher deaths compared to non-Appalachian regions. Poverty and limited access to physicians contribute to the deficit, emphasizing the need for improved prenatal care and healthcare policies.

Why belly fat isn't all bad

Researchers have found that the omentum's fat cells can suppress the immune system by sequestering activated T cells, a finding that could lead to new drugs with fewer side effects. The omentum also helps regenerate damaged tissues through mesenchymal stem cells.

Study: Insomnia linked to hypertension

A new study from Henry Ford Hospital found that individuals with insomnia are more likely to develop hypertension due to frequent nighttime wakings and delayed sleep latency. The research highlights the importance of addressing sleep disorders to prevent related health issues.

Mystery to the origin of long-lived, skin-deep immune cells uncovered

Researchers at A*STAR's Singapore Immunology Network discovered that long-lived, skin-deep immune cells called Langerhans cells originate from two distinct embryonic sites - the early yolk sac and the foetal liver. These cells play a critical role in initiating protective responses against harmful foreign invaders.

Modeling the demise of migrating brain tumor cells

A theoretical model simulates brain tumor cell evolution under treatment, revealing that peripheral cells need to be targeted. The model suggests enhancing TTF treatment by applying specific frequencies, leading to increased plasma membrane permeability and cancer cell demise.

Studies show new drug to be effective in treating skin cancer, Stanford researchers say

A new study published in the New England Journal of Medicine shows that vismodegib is effective in treating basal cell carcinoma, a common cancer caused by sun exposure. Researchers found that patients with Gorlin syndrome who took vismodegib developed an average of two new tumors per year, compared to 29 in those taking placebo.

We are drinking too much water

Research suggests that encouraging people to drink more water is driven by market interests rather than a need for better health. A balanced diet and lifestyle are key to weight loss, with fluid intake from unprocessed sources being equally important.

Higher taxes, smoke-free policies are reducing smoking in moms-to-be

A recent study found that higher taxes on cigarettes and implementation of smoke-free policies are effective in reducing smoking during pregnancy. The study, published in the American Journal of Preventive Medicine, also showed that these policies can help prevent relapse after delivery, with a $1.00 increase in tax resulting in a 4.8 ...
