Lyman-α emission from atomic hydrogen shows the location of warm gas and is ubiquitous around galaxies between redshifts of 3 and 6, thereby covering nearly all the sky.

DEET interferes selectively with chemotaxis of Caenorhabditis elegans nematodes, and mutations in the str-217 gene or silencing of the pair of chemosensory neurons that express it makes worms DEET-resistant.

Observations of a jet from a strongly magnetized neutron star reveal that strong magnetic fields do not prevent jet formation and suggest that stellar properties influence jet power.

New blood vessel endothelial cells arise from differentiation of erythro-myeloid progenitor cells to complement the proliferation of pre-existing endothelial cells.

Combination therapy with the anti-HIV-1 monoclonal antibodies 3BNC117 and 10-1074 maintains long-term suppression in the absence of antiretroviral therapy in individuals with antibody-sensitive viral reservoirs.

Complex tertiary alkylamines are prepared in one step from readily available amines, carbonyls and alkenes, via the visible-light-mediated reduction of in-situ-generated iminium ions to form alkyl-substituted α-amino radicals.

Detection of biometric signals by self-powered electronic devices that are highly flexible and can be applied to skin.

Analyses of the relationships between temperature, moisture and seven key plant functional traits across the tundra and over time show that community height increased with warming across all sites, whereas other traits lagged behind predicted rates of change.

In mouse and human liver models, blood vessel perfusion and mechanical stretching release angiocrine signals from endothelial cells that lead to hepatocyte survival and liver growth.

The movements of relocated wild animals reveal that a lost migratory skill was regained over successive generations. This suggests that skill improvements can occur over time as animals learn expertise from each other.

Current biological sensors require bulky external power sources. Ultrathin solar cells have now been fabricated that can power flexible, wearable sensors for the precise and continuous monitoring of biological signals.

Contrary to previous assumptions, it seems the cells that line blood vessels are derived from more than one source. In addition to their known developmental path, they can arise from progenitors of embryonic blood cells.

Increases in biomechanical forces in the liver’s blood vessels have now been shown to activate two mechanosensitive proteins. The proteins trigger blood-vessel cells to deploy regenerative factors that drive liver growth.

Mechanical structures have been made that exhibit self-guided, multi-step sequences of shape changes in response to an applied force. Such structures could have applications in flexible electronics and soft robotics.

Drug treatments for HIV infection require the long-term use of daily medication that can have toxic side effects. A pair of HIV-targeting antibodies might offer an alternative therapeutic approach.

To make my research more useful for people deciding how to plant crops and prevent flood damage, I asked for their help, says Carolina Vera.

Nearly 1,000 babies were born with the infection in 2017.

The University of Pisa and the European Research Council also said that they are opening investigations into Alessandro Strumia's conduct.

James Allison and Tasuku Honjo pioneered treatments that unleash the body’s own immune system to attack cancer cells.

Giving media interviews can raise scientists’ profiles if they prepare well and manage expectations.

The object never gets closer to the Sun than 65 times the Earth–Sun distance.
