I. Space & Deep Space
1. Soyuz MS-28 lands: NASA’s Chris Williams and two Roscosmos cosmonauts end a 241-day stay
Summary:
On July 26, 2026, NASA astronaut Chris Williams and Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev returned from the International Space Station aboard Soyuz MS-28, making a parachute-assisted landing southeast of Dzhezkazgan, Kazakhstan, at 5:27 a.m. CDT (3:27 p.m. Kazakhstan time). The trio undocked at 2:03 a.m., after 241 days in space, 3,856 orbits, and more than 102 million miles; they launched Nov. 27, 2025. It was the first flight for Williams and Mikaev and the second for Kud-Sverchkov. Williams supported cancer-treatment research and in-space manufacturing of materials for high-performance computing, and completed two spacewalks to prepare power-system upgrades and replace a faulty Canadarm2 joint.

Commentary:
A “routine” crewed landing is still a hard reliability exam—what matters next is how the 241 days of science translate into Earth-side and exploration value.
2. After Spanish wildfires: NASA’s Madrid DSN complex and an ESA station show no major structural damage on first checks
Summary:
Following the July 24 evacuation of NASA’s Madrid Deep Space Communications Complex (MDSCC) about 65 km west of Madrid, NASA press secretary Bethany Stevens said on July 25 that an initial inspection found damage mainly to pavement and surrounding vegetation, with no significant structural damage to antennas or buildings; fuller assessments will proceed as access allows. MDSCC is one of three Deep Space Network hubs, with one 70-meter and five 34-meter antennas; none have actively talked to spacecraft since at least July 24, with Goldstone and Canberra taking over. ESA’s ~35-meter station near Cerberos (~77 km west of Madrid) likewise appears unharmed based on available information, with all personnel safe, though on-site inspection is not yet possible. By late July 25, nearly 300,000 people in Spain and France had been evacuated due to fires.

Commentary:
Escaping catastrophe is not the same as returning to service—while Goldstone’s 70-meter antenna is already offline for repairs through 2028, any prolonged Madrid outage tightens an already strained deep-space link budget.
3. First sugar detected in the interstellar medium: erythrulose in a Galactic Centre cloud
Summary:
A team led by Izaskun Jiménez-Serra at Spain’s Centre for Astrobiology reports in Nature Astronomy (July 13, 2026) the first direct detection of a sugar in the interstellar medium—the four-carbon ketose erythrulose—toward molecular cloud G+0.693−0.027 near the Galactic Centre, using the Yebes 40 m and IRAM 30 m telescopes. Twelve spectral features match laboratory measurements; the sugar appears at least eight times more abundant than analogous three-carbon sugars, which were not detected. Models indicate efficient formation on icy dust grains from two-carbon aldehydes and alcohols; abundance estimates imply roughly 0.5–50 million tonnes could have reached early Earth during the Late Heavy Bombardment. CBC and other outlets followed the story on July 26.

Commentary:
Moving sugars from meteorite inference to molecular-cloud detection raises the bar for prebiotic chemistry—next comes ketose-to-aldose pathways and replication across more clouds.
II. Biomedicine & Health
4. Nature Medicine: a “double neural bypass” restores hand movement and touch after complete tetraplegia
Summary:
Chad Bouton and colleagues at the Feinstein Institutes report in Nature Medicine (July 16, 2026) a double neural bypass (DNB) that couples an intracortical brain–computer interface with targeted, patterned neuromodulation of the spinal cord and cortex, so movement-intention signals drive the user’s own hand in real time while promoting lasting sensorimotor gains even after the system is off. The platform uses recurrent networks and reinforcement learning for fine grasp, plus patterned spinal stimulation and activity-informed cortical microstimulation (“cortical mirroring”). In a participant with chronic C4 sensory/C5 motor complete tetraplegia, the approach enabled self-feeding and delicate object handling, with durable gains in elbow flexion and wrist tactile sensation; intended hand movements remained decodable for more than five months without repeated retraining. Authors stress the need for broader injury cohorts and note the system’s specialization and staffing demands.

Commentary:
Binding immediate function to off-device plasticity is a watershed from assistive gadgets toward neuro-reparative therapy—scalability and safety remain the next gates.
5. FDA approves Jideytro (zidesamtinib) for previously treated ROS1-positive NSCLC
Summary:
Per GSK and clinical coverage dated July 22, 2026, the U.S. FDA approved Jideytro (zidesamtinib), a ROS1-selective inhibitor from Nuvalent, for adults with locally advanced or metastatic ROS1-positive NSCLC previously treated with a ROS1 kinase inhibitor—ahead of the Sept. 18 target date, after Breakthrough Therapy and Orphan Drug designations. Approval rests on the global single-arm ARROS-1 phase I/II trial (NCT05118789) in 117 pretreated patients: overall response rate 44% (95% CI 34–53%), with duration-of-response rates of 82% at six months and 69% at 12 months, including meaningful, durable responses in patients with brain metastases and ROS1 resistance mutations. The drug inhibits ROS1 including resistance mutations.

Commentary:
Near-half responses after multiple TKIs fill a post-resistance gap—real-world intracranial durability and evolving resistance maps will set its ceiling.
6. Nature: MIT builds high-water-content hydrogels that “breathe,” wearable for 10 days
Summary:
MIT’s Xuanhe Zhao and colleagues report in Nature a viscoelastic phase separation (VPS) strategy that creates a non-collapsible 3D air network inside high-water hydrogels, reaching oxygen permeability of 185 barrer at ~70 vol% water—about a tenfold gain over pristine gels—across diverse chemistries and form factors. Ten-day continuous wear tests limited fluid buildup and preserved skin health. As ECG electrodes, the material kept clearer signals through cycling and sweat than conventional hydrogel electrodes and recorded usable traces during sleep, work, walking, and exercise. Zhao cites near-term paths in wearables, wound dressings, and skin monitors, while noting needs for long-term biocompatibility, large-animal studies, sterilization, scale-up, shelf life, and regulatory safety. ScienceAlert covered the work on July 26.

Commentary:
Hydrogels have long traded water content against breathability—embedding stable air pathways is the missing lesson for sensors that must last through a weekend.
III. Climate, Energy & Environment
7. GOSAT inversion: 2023–2024 CO₂ surge driven by weaker land sinks, with northern mid–high latitudes ~one-quarter of the land shortfall
Summary:
Japan’s National Institute for Environmental Studies (press release July 22, 2026; paper in Geophysical Research Letters June 27) used GOSAT (“Ibuki”) column CO₂ with the NISMON-CO2 inverse system to estimate surface fluxes. The large 2023–2024 atmospheric CO₂ rise was attributed mainly to reduced net land-ecosystem uptake rather than a step-up in fossil emissions alone. Extra carbon left in the air over two years totaled about 2.22 GtC from the tropics and 0.84 GtC from northern mid–high latitudes—roughly one-quarter of the land-sink weakening—where warming boosted respiration and soil decomposition and suppressed photosynthesis, with limited fire contribution. GOSAT recorded a 2024 global annual growth of 3.5 ppm/yr, its largest on record.

Commentary:
Land-sink “walkouts” are no longer a tropics-only story—satellite evidence that mid–high latitudes are climate-sensitive makes natural carbon buffering look thinner than many net-zero plans assume.
8. Nature Energy: climate-informed siting can blunt wind–solar adequacy risks at near-zero extra cost
Summary:
An MIT-led study in Nature Energy (July 16, 2026) couples ~12 km climate projections with county-level power-system optimization for decarbonized New England and Texas grids. Planning to historic climate can raise resource-inadequacy frequency up to fivefold by mid-century as multi-day renewable shortfalls collide with rising cooling demand and transmission bottlenecks. Climate-informed designs mitigate cheaply: Texas can preserve adequacy at near-zero added cost by shifting wind westward; New England needs about a 2.34% investment increase via solar and transmission nearer load centers. The authors argue planners must move beyond aggregate capacity targets to high-resolution, climate-aware spatial siting.

Commentary:
The second half of intermittency is not “how much more to build” but “where”—wrong siting can multiply blackout risk fivefold; right siting barely raises the bill.
IV. Fundamental Research & Cross-Disciplinary Frontiers
9. Science Advances: orbital-angular-momentum twisted lasers distinguish molecular handedness by fragment counts
Summary:
Researchers from the Tata Institute of Fundamental Research and IIT Bombay/Hyderabad report in Science Advances that femtosecond beams carrying both spin and orbital angular momentum (OAM), directed at gaseous R-/S-camphor at TIFR Hyderabad and read out with time-of-flight mass spectrometry, produce fragment yields that depend on how the light’s twist matches molecular handedness—enhancing chiral selectivity by up to about fourfold without angular coincidence detection. Phys.org covered the result on July 26, noting potential for simpler enantiomer analysis in chemistry, biology, and pharma.

Commentary:
Treating light’s helix as a probe strips a layer of hardware from chirality assays—the industrial test is moving from camphor to real drug mixtures.
10. PRL “electron lighthouse”: two-color lasers steer semiconductor electron currents without an applied field
Summary:
University of Michigan physicists Steven Cundiff, Yiming Gong and colleagues report in Physical Review Letters (July 16, 2026) an experimental “electron lighthouse”: two phase-coherent infrared laser colors drive a directional photocurrent in a semiconductor via quantum interference, with no applied electric field; rotating the polarizations sweeps the electron-beam direction like a lighthouse lamp. Devices were built at the Lurie Nanofabrication Facility under conditions that avoided stray fields. Authors link the effect to interference among optical absorption pathways and sketch applications in sensing, imaging, and optoelectronic signaling. ScienceAlert featured the work on July 26.
