New system for detection of single atoms

Researchers have developed a new technique to detect individual neutral atoms, which is more accurate and sensitive than previous methods. The system uses a novel means of altering laser light polarization to 'see' the scattered photons, allowing for real-time detection with a speed of less than one-millionth of a second.

Environmental exposures may damage DNA in as few as 3 days

A new study finds that exposure to particulate matter can reprogram genes associated with tumor suppression, affecting cancer development and outcomes. The changes are detectable after just three days of exposure, raising hopes for early interventions to prevent or reverse gene programming.

Early mobilization of patients in ICU improves outcomes

A randomized trial of 100 ICU patients found that daily mobilization and sedative interruption improved functional status and reduced delirium at hospital discharge. Nearly 60% of early mobilization patients achieved independence, compared to only one third in the control arm.

The evolutionary foundation of genomic imprinting in lower vertebrates

Research reveals genomic imprinting in goldfish shares similarities with mammalian Imprinting, challenging the idea of unique evolutionary event for mammals. The study found parental differential methylation regions in goldfish, indicating a primitive form of genomic imprinting in early vertebrate evolution.

Study finds genetic links to age of first menstrual period and menopause

Researchers have identified two chromosomal regions associated with the age at which females experience their first menstrual period (menarche) and the onset of natural menopause. The study may help shed light on the prevention of breast and endometrial cancer, osteoporosis, and cardiovascular disease.

Sleep may be factor in weight control

Researchers found that short sleepers had higher BMI and lower sleep efficiency compared to long sleepers. Overweight individuals also tended to be more active, but this did not lead to reduced weight gain.
