Researchers used novel approach with historic film to discover just how endangered Kemp’s ridley sea turtles are. Kemp's ridley turtles are currently classified as critically endangered on the IUCN's Red List of Threatened Species. The species was on the brink of extinction in the 1980s, but a Mexico-U.S. bi-national conservation program initiated in 1978 was able to reverse its decline.
190 light-years out from Earth, exoplanet HD 80606b loops very close to its parent star every 111 days; its temperature soaring – then dipping –1500°F(816° C) in less than one of its 90-hour days.
An anonymous reader writes about a newly found vulnerability in Truecaller: Security researchers have found a flaw in Truecaller, a popular service that indexes phone numbers and helps users block spammers and telemarketers. An article on Softpedia explains the vulnerability, "When users first install the Android app, they are prompted to enter their phone number, email address, and other personal details. This information is verified by phone call or SMS message. Upon opening the app for the second time, no login screens are shown. In a proof-of-concept code shared with Softpedia, researchers were able to retrieve personal details for other users based on an IMEI code just by interacting with the app's servers. The servers exposed data such as the user's Truecaller account name, his gender, email address, profile image, home address, and whatever else was stored in his profile. Additionally, the IMEI code also allowed the researchers to modify account settings."

Scientists performed four experiments in which they examined vessel type, hormone, activated charcoal concentrations, and using a vermiculite substrate to improve the post-rooting stage of an American chestnut propagation protocol. They recommended using semisolid post-rooting medium containing activated charcoal and humic acid in disposable fast-food takeout containers. A trend evidenced across the experiments was that activated charcoal enhanced root growth but slightly decreased shoot tip survival.
Hydroponic experiments evaluated the effects of salinity on biomass accumulation and nutrient levels of four types of Agave. Several Agave species showed variation in response to high levels of salinity. Agave parryi and Agave weberi plants were determined to be relatively tolerant to high levels of salinity; the scientists said both show potential to be grown as crops in saline soils in semiarid regions.
Approximately 37 million people are living with HIV. Antiviral medications are used to control the disease and prevent its progression to AIDS. Although antivirals improve health and increase survival for people with HIV, their use also has been linked to the development of cardiovascular disease. Now, researchers have identified an enzyme that may reduce the risk of cardiovascular disease caused by HIV medications.
A new material is more solid and 30 percent lighter than standard gold, scientists report. In their study, the team investigated grain boundaries in nanocrystalline np-Au and found a way to overcome the weakening mechanisms of this material, thereby suggesting its usefulness.
A new analytical tool has forged ahead with its previously developed DNA-PAINT and Exchange-PAINT super-resolution microscopy platform to now count different molecular species in biological samples with high accuracy and precision.
A mutation that causes a rare systemic disorder known as X-linked reticulate pigmentary disorder (XLPDR) has been discovered and, significantly, the unexpected cellular mechanism by which the mutation causes the disease.
Researchers detected evidence of concussions in patients up to 7 days after their injury using a simple blood test -- which could greatly expand the window for diagnosing concussions, especially in patients who experience a delayed onset of symptoms.
The largest network to date of connections between neurons in the cortex, where high-level processing occurs, has been published. It has revealed several crucial elements of how networks in the brain are organized.
Experts applaud Oregon's new birth control law, which allows women age 18 or older to obtain some methods of hormonal contraception directly from pharmacies, without having to visit a prescribing clinician, yet note how the law could go even further to improve access to all forms of contraception, according to a new article.
To provide oncologists a way to detect a single molecule of an enzyme produced by circulating cancer cells, physicists and engineers have developed an optical sensor, based on nanostructured metamaterials, that's 1 million times more sensitive than the current best available. The device proved capable of identifying a single lightweight molecule in a highly dilute solution.
Scientists have resurrected a discarded drug that helps human cells in a lab dish fight off two different viruses. Based on what they learned about how the drug works, it might also help fight the viruses that cause Ebola, dengue and Zika, among others, they say.
Quantum effects are the reason that hydrogen sulphide -- which has the distinct smell of rotten eggs -- behaves as a superconductor at record-breaking temperatures, which may aid in the search for room temperature superconductors, researchers have found.
People with cancer have tumor DNA in their blood. A new way to quiet background 'noise' in the blood sample allows researchers to sequence minute quantities of these molecules to improve diagnosis and treatment.
A "piezo-optomechanical circuit" has been developed that converts signals among optical, acoustic and radio waves. A system based on this design could move and store information in next-generation computers.
Researchers have successfully directed stem cell-derived neurons to regenerate lost tissue in damaged corticospinal tracts of rats, resulting in functional benefit, a new article reports.
Kuvée is a wine system for the thinking person's drinking person. The post The Kuvée: A Brilliant Gadget That Keeps Swappable Wine Canisters Fresh for a Month appeared first on WIRED.
An anonymous reader writes: Citizens of mainland China unexpectedly found themselves with unfettered access to Google search late last night, commencing a golden age of censorship-free searching that lasted all of 105 minutes. For the duration of the film Edward Scissorhands, lasting from 11:30pm on Sunday to 1:15am on Monday morning, Google's search -- but not other services like Gmail or YouTube -- was unblocked
