It is one of the most hotly debated topics in today’s workplace: Is allowing employees to log in from home a few days a week good for their productivity, careers, and job satisfaction? Nicholas Bloom, a Stanford economist and one of the foremost researchers on work-from-home policies, has uncovered compelling evidence that hybrid schedules are a boon to both employees and their bosses. In a study, newly published in the journal Nature, of an experiment on more than 1,600 workers at Trip.com — a Chinese company that is one of the world’s largest online travel agencies — Bloom finds that employees who work from home ...

hat: Researchers have identified inherited genetic variants that may predict the loss of one copy of a woman’s two X chromosomes as she ages, a phenomenon known as mosaic loss of chromosome X, or mLOX. These genetic variants may play a role in promoting abnormal blood cells (that have only a single copy of chromosome X) to multiply, which may lead to several health conditions, including cancer. The study, co-led by researchers at the National Cancer Institute, part of the National Institutes of Health, was published ...

A Dartmouth study conducted on fruit flies reports the first evidence in any organism that oocytes—the cells that become eggs—regularly rejuvenate the critical protein linkages that bind chromosomes together. The findings are a potentially important step toward helping women reduce their risk of pregnancy complications as they age, the researchers report in the journal Current Biology.    Women are born with the oocytes they will have for life, and the cohesive linkages that connect chromosomes are established in those cells prenatally. When they reach childbearing age, ovulation triggers the ...

BOSTON – Cardiovascular disease (CVD) is the leading cause of death worldwide, accounting for approximately one in every three deaths, with more than 20 million deaths reported in 2021 according to a 2024 World Heart Federation report. Improvements in heart disease prevention, treatment and intervention have led to substantial declines in cardiovascular deaths in recent decades, but climate change caused by the continued combustion of fossil fuels may undermine this progress. Over the last century, NASA confirms the average global temperature has risen by more than two degrees Fahrenheit, leading to long-term shifts in average weather patterns, disturbance ...

Tokyo Medical and Dental University (TMDU) researchers harness long-read RNA sequencing to decode genetic intricacies and disease links. Tokyo, Japan – Alternative splicing, a process where a single gene can give rise to multiple different proteins via inclusion or exclusion of certain segments of the gene sequence, is known to occur in over 90% of human genes. This leads to the production of numerous transcript isoforms (splice variants of an expressed gene) crucial for protein function and cellular processes. Despite previous research on mechanisms underlying alternative splicing ...

Many modern bridges use orthotropic steel bridge decks (OSBD), the decks being the surface sections of the bridge. OSBDs were designed to be lightweight and economical. However, this design has shown increasing issues with pavement cracking and fatigue damage at the welds that connect the bridge deck to the bridge superstructure. Fatigue damage is damage that accrues over time with use.   To ameliorate these problems, a new bridge deck was designed. The composite bridge deck system (CBD) added a layer of concrete to decrease the probability of damage due to fatigue. More recently the use of high-performance materials, such as ultra-high-performance ...
