A rapidly widening Ebola epidemic in Africa is being driven by the Bundibugyo virus, a strain that previously caused only two small outbreaks. Scientists are accelerating work to develop vaccines and treatments tailored to this lesser known variant.
9:54 AMThe New York TimesA global analysis finds nitrogen pollution can either accelerate or sharply suppress forest soil respiration, depending on ecosystem conditions. The work identifies tipping points that could shift how forests store carbon and respond to climate stress.
10:11 AMScienceDailyObservations near Jupiter link supersonic shocks to a simple scaling law for how particles get accelerated in space. The work points to transient plasma structures as the key drivers that set particle energies.

A rapidly widening Ebola epidemic in Africa is being driven by the Bundibugyo virus, a strain that previously caused only two small outbreaks. Scientists are accelerating work to develop vaccines and treatments tailored to this lesser known variant.
Why it matters
A growing epidemic caused by a poorly characterized Ebola strain raises the odds of delayed medical response and wider regional spread.
Summary
A global analysis finds nitrogen pollution can either accelerate or sharply suppress forest soil respiration, depending on ecosystem conditions. The work identifies tipping points that could shift how forests store carbon and respond to climate stress.
Why it matters
Nitrogen pollution can unpredictably alter a major global carbon sink, raising the risk that climate projections and mitigation plans miss real-world forest feedbacks.
Summary
Observations near Jupiter link supersonic shocks to a simple scaling law for how particles get accelerated in space. The work points to transient plasma structures as the key drivers that set particle energies.
Why it matters
A reliable scaling law for acceleration improves space-weather prediction and spacecraft risk planning in high-radiation environments.

A long-running effort to construct a human genome from scratch still has a scientific case, even after years of technical hurdles and debate about whether it is necessary. The argument is that a fully designable genome would enable experiments and controls that reading and editing natural DNA cannot provide.
8:00 PMNatureAstronomers traced a class of repeating cosmic radio signals to a rare binary system where a white dwarf pulls material off a red dwarf companion. The accretion process produces radio and X-ray bursts on a 1.4-hour cycle, pinpointed using Australia’s ASKAP radio telescope.

A long-running effort to construct a human genome from scratch still has a scientific case, even after years of technical hurdles and debate about whether it is necessary. The argument is that a fully designable genome would enable experiments and controls that reading and editing natural DNA cannot provide.
Why it matters
If scientists can build and systematically vary human genomes, biology, medicine, and biosecurity policy all move from editing what exists to engineering what is possible.
Summary
Astronomers traced a class of repeating cosmic radio signals to a rare binary system where a white dwarf pulls material off a red dwarf companion. The accretion process produces radio and X-ray bursts on a 1.4-hour cycle, pinpointed using Australia’s ASKAP radio telescope.
Why it matters
Pinning the signals to a concrete, repeatable stellar system turns a mystery phenomenon into a tool for studying binary evolution and extreme plasma physics.
