The human genome is, at long last, complete

Even after 20 years of upgrades, eight percent of the human genome was still left unsequenced and unstudied. Until now.

New comprehensive map of the portal to the cell’s nucleus

The findings, which may have implications for a wide range of human diseases, suggest that nuclear pore complexes vary in structure and function even within a single nucleus.

Llama antibodies could help fight SARS-CoV-2 variants

Scientists have identified hundreds of llama-derived antibodies that potentially could be developed into a COVID treatment. They hope such a drug would be potent against different variants of the coronavirus, including Omicron.

Stem cell memories may drive wound repair—and chronic disease

Epidermal stem cells that hail from the hair follicle retain memories of their journey to the skin's surface. Those memories are a boon for wound repair, but may also contribute to chronic diseases and cancer.

Study detects origins of Huntington's disease in two-week-old human embryos

The findings shed new light on the root causes of this disease, which leads to the degeneration of neurons in midlife.

Lonely flies, like many humans, eat more and sleep less

If COVID-19 lockdowns scrambled your sleep schedule and stretched your waistline, you're not alone. Fruit flies quarantined in test tubes sleep too little and eat too much after only one week of social isolation.

How cells draw on memories of past inflammation to respond to new threats

A new study uncovers a near-universal mechanism behind this phenomenon, known as inflammatory memory.

Putting the brakes on immune reactions

Helper T cells may play a dual role in the immune system, both encouraging and suppressing the process by which B cells mature.

New findings to boost IVF success rates

New research casts doubt on a genetic test used to screen would-be embryos for IVF implantation. The findings suggests that these embryos can develop into healthy babies regardless of whether or not they’ve been flagged as defective by the test.

Scientists release error-free genomes of 25 animals—with another 70,000 coming up

Scientists have launched an ambitious effort to produce high-quality reference genomes for all vertebrate species, from mammals to birds and reptiles. The result could be discoveries with implications for animal conservation as well as human health and disease.
