Researchers observed association between standing and insulin sensitivity – standing more may help prevent chronic diseases

A Finnish study discovered a positive association between standing and improved insulin sensitivity in adults with increased risk of type 2 diabetes and cardiovascular diseases. The researchers found that increasing daily standing time can help prevent chronic diseases, even if physical activity recommendations are not met.

Identifying activity origin of single-atom catalyst through atom-by-atom counting

A new methodology, EMARS, was developed to directly identify the activity origin of Pt/Al2O3 industrial reforming catalyst by analyzing over 18,000 Pt atoms. The study found that density of supported Pt1 single atoms and Pt-Pt distance larger than 0.38 nm are correlated with aromatic production activity.

Childhood gender nonconformity in boys linked to early androgens

Researchers studied individuals with isolated GnRH deficiency, a rare endocrine disorder that affects hormone production. Men with IGD reported higher levels of childhood gender non-conformity, while women did not differ from typical women. This suggests that early androgens play a direct role in shaping male brain development.

Scientists discover that taste cells can control a whole animal’s foraging strategy

Researchers developed a computer model revealing how single brain cells in nematode worms sense and process environmental information to drive decision-making. The study found that sensory cells use salt cues as 'navigation beacons' to direct foraging behavior, controlling the animal's search strategy.

Off-target immune response could predict COVID-19 severity

A new study found that people hospitalized with COVID-19 have elevated levels of autoimmune antibodies in their blood, which are strongly linked to disease severity. Patients with high levels of these autoantibodies were five to seven times more likely to develop severe disease than those with stable antibody levels.

When everyone works remotely, communication and collaboration suffer, study finds

A new study of 61,000 Microsoft employees found that working from home causes workers to become more siloed in how they communicate, engage in fewer real-time conversations, and spend fewer hours in meetings. The study's findings suggest that a full-time remote workforce may have a harder time acquiring and sharing new information.

Warmer bottom water temperatures increased methane seepage in the NW Barents Sea

Researchers reconstructed the bottom water temperature record in the Northwest Barents Sea over the last 18,000 years and found that warmer temperatures led to increased methane seepage. The study suggests that these events played a key role in driving the retreat of the former ice sheet and destabilizing gas hydrates.

Disease genes help developing brains

Scientists have identified two new candidate genes, ULK4 and PTTG1, that positively influence the development of an embryo by restoring a strong Sonic Hedgehog signaling pathway. This finding provides new insights into the causes of holoprosencephaly, a congenital malformation affecting around one to four in every 1,000 unborns.

Lurbinectedin does not improve overall survival in SCLC -- some positive action in combination with doxorubicin after chemotherapy

A multicenter clinical trial tested the use of lurbinectedin in patients with small cell lung cancer (SCLC), which did not meet its primary end point of overall survival. However, the combination of lurbinectedin and doxorubicin was found to be active in patients with SCLC after one prior platinum-based chemotherapy.
