First Circadian Clock Gene Cloned In Mammals

Researchers successfully cloned the Clock gene, a key regulator of circadian rhythms in mammals. The gene's identification provides insight into the molecular mechanisms underlying circadian rhythm entrainment and expression, potentially leading to new treatments for sleep disorders and jet lag-related issues.

Many Men In "Safe" PSA Range Have Cancer

A new study by Washington University School of Medicine researchers found that a surprising 22 percent of men with prostate cancer had PSA levels between 2.6 and 4, highlighting the need for yearly PSA tests for men over 50. The study suggests that doctors may be missing cancers in this range due to outdated guidelines.

In The Air And On The Ground: Scientists Seek Clues To Better Weather Forecasting

Researchers are collecting data from the lowest few thousand feet of the atmosphere, known as the boundary layer, to better understand its interactions with the surface. The Cooperative Atmosphere-Surface Exchange Study (CASES) aims to improve weather forecasting by measuring heating and evaporation rates at the surface.

It Takes A Full Day To Raise Two Kids

Researchers found that parents with two children spend an average of 57,661 hours raising their kids to age 18, exceeding the previously estimated 7.25 hours a day. This includes primary child care and secondary child care activities. The study also revealed that mothers spend more time on primary child care than fathers.

Blizzard Snow Loads And Building Codes

A study by Cornell University researchers found that most buildings in the Northeast region exceeded minimum building code requirements for snow loads during the Blizzard of '96. The accumulation of snow from two storms led to increased snow weight on roofs, causing collapses in some areas.
