Sleep tight: genome secrets could help beat the bedbug's bite

No. Bedbugs! These tiny insects have staged a global resurgence in the past two decades after being nearly eradicated in many regions, but scientists on Tuesday unveiled a complete genetic map of the bedbug that could guide efforts to foil the resilient parasite. "This is an enormous new tool for researchers interested in controlling this pest," said George Amato, director of the Sackler Institute for Comparative Genomics at the American Museum of Natural History in New York. "Bed bugs are now very widespread in most major cities around the world, and they have increasingly become resistant to insecticides, making them harder to control," American Museum of Natural History entomologist Louis Sorkin said.

Scientists' path to usable Zika vaccine strewn with hurdles

Making a shot to generate an immune response against Zika virus, which is sweeping through the Americas, shouldn't be too hard in theory. For a start, scientists around the world know even less about Zika than they did about the Ebola virus that caused an unprecedented epidemic in West Africa last year. Ebola, due to its deadly power, was the subject of bioterrorism research, giving at least a base for speeding up vaccine work.

How Zika Virus Spreads: Chain of Events Explained

Zika virus is "now spreading explosively in the Americas," World Health Organization (WHO) Director-General Dr. Margaret Chan said on Thursday (Jan. 28), and 3 million to 4 million people in the Americas could be infected by the virus this year alone, according to the latest WHO estimates. However, U.S. officials have said that the virus is likely to cause only small outbreaks in this country. To understand how the Zika virus spreads to new regions, and how researchers can tell whether a region is likely to experience large outbreaks or small ones, Live Science asked the experts what sequence of events has to happen in order for the virus to become established in a new region.

Sexually Transmitted Zika Case Confirmed in Texas

A person in Dallas appears to have spread the Zika virus to another person through sex, Texas health officials said today. Officials at Dallas County Health and Human Services (DCHHS) said that a person in the area was infected with the Zika virus after having sexual contact with another person who had returned from Venezuela, where the virus is spreading, and was ill. "Now that we know Zika virus can be transmitted through sex, this increases our awareness campaign in educating the public about protecting themselves and others," Zachary Thompson, the DCHHS director, said in a statement.

Small country, big Universe - Luxembourg aims for space business

By Meredith McGrath BRUSSELS (Reuters) - Luxembourg, the tiny European Union state nestled between France, Germany and Belgium, has a big new goal - it wants to be a center for space mining. Primarily known for its fund management and private banking industry, the duchy is promoting a law that would make it the first in Europe to give legal clarity to the commercial exploitation of asteroids. "In the long-term, space resources could lead to a thriving new space economy and human expansion into the solar system," Etienne Schneider, Luxembourg's economy minister told a press conference.

Massive Bird Die-Off Puzzles Alaskan Scientists

Thousands of dead seabirds have washed up on Alaskan shores over the past nine months. Nearly 8,000 common murres (Uria aalge) were found along the shores of Whittier, Alaska, in early January. Over the New Year's holiday, Alaska experienced four days of gale-force winds from the southeast that resulted in dead birds washing ashore, said Robb Kaler, a wildlife biologist for the Alaska branch of the U.S. Fish and Wildlife Service (USFWS).

Meet 'Squishy Fingers': Flexible Robot Advances Undersea Research

Meet "Squishy Fingers," a new remotely operated vehicle designed to delicately grab and take samples of coral. The ROV, described in a Jan. 20 study in the journal Soft Robotics, will help researchers collect specimens from deep underwater reefs without damaging the corals' fragile bodies. "If we're going to go down and study these systems, then we should be as gentle as we possibly can," said study co-senior author David Gruber, an associate professor of biology at Baruch College in New York City and a National Geographic emerging explorer.

Spacewalking Russian cosmonauts begin work outside space station

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Two veteran Russian cosmonauts floated outside the International Space Station on Wednesday to replace experimental equipment that is testing how materials and biological samples fare in the harsh environment of space. Station flight engineers Yuri Malenchenko and Sergey Volkov left the station's airlock at 7:55 a.m. EST for what was expected to be a 5-1/2-hour spacewalk, a live broadcast on NASA Television showed. Among the cosmonauts' first tasks was to cast off a flash drive into space, giving a ceremonial send-off to recorded messages and video from last year's 70th anniversary of Victory Day, said NASA mission commentator Rob Navias.

Flu Season Is Here; CDC Warns of Severe Cases in Young Adults

Flu season has started, and although so far it has not been as bad as last year's, there have been reports of some young and middle-age adults developing severe cases of influenza, according to the Centers for Disease Control and Prevention. Today (Feb. 1), the CDC announced that flu cases are increasing across the country. The most common flu strain circulating now is H1N1, the same strain of flu that caused a pandemic in 2009.

Moms' Beneficial Vaginal Microbes Given to C-Section Babies by New Method

In a new procedure, doctors wiped down the skin of newborns delivered by cesarean section with a gauze carrying their mothers' vaginal fluid. The doctors found that this was a successful way to transfer beneficial microbes from pregnant women to their infants, a new pilot study suggests. This small study showed that this swabbing procedure, known as vaginal microbial transfer, can safely and effectively change the microbial communities of babies delivered by C-section to make them more closely resemble those of vaginally born babies, said José Clemente, an assistant professor of genetics at the Icahn School of Medicine at Mount Sinai in New York City and a co-author of the research, published today (Feb. 1) in the journal Nature Medicine.

Prehistoric man enjoyed roasted tortoise appetizers, Israeli archaeologist says

Prehistoric cave-dwellers enjoyed munching on tortoises roasted in their shells as an appetizer or side dish, Ran Barkai, an archaeologist at Tel Aviv University, said on Tuesday. Barkai helped lead a research team who found 400,000-year-old tortoise shells and bones in a cave in Israel that showed hunter-gatherers butchered and cooked tortoises as part of a diet dominated by large animals and vegetation. "Now we know they ate tortoises in a rather sophisticated way," Barkai said.

What's That Word? Marijuana May Affect Verbal Memory

Years of smoking pot may have an effect on a person's verbal memory, which is the ability to remember certain words, a new study finds. For every five years of marijuana use, researchers found that, on average, one out of two people remembered one word fewer from a list of 15 words, according to the study. Long-term use was not, however, significantly associated with decreases in other measures of cognitive function, such as processing speed or executive function, the researchers wrote in the study, published today (Feb. 1) in the journal JAMA Internal Medicine.

Microcephaly Linked to Zika Virus Is a 'Public Health Emergency,' Officials Say

The recent, dramatic increase in babies in Brazil born with microcephaly — underdeveloped skulls and brains — that has been linked with the Zika virus constitutes "a public health emergency of international concern," Dr. Margaret Chan, director-general of the World Health Organization, said today. Clusters of microcephaly and other neurological complications that are possibly linked to the virus make up "an extraordinary event and a public health threat to other parts of the world," Chan said at a news conference in Geneva today (Feb. 1). However, Chan noted that the Zika virus itself, which is spread by mosquitos and typically causes only mild symptoms and sometimes none at all, did not merit emergency status.

Want to Make a Volcano Explode? Just Add Heat

Volcanoes erupt explosively when gas-charged magma reaches Earth's surface. The formation and growth of gas bubbles are complex processes that fascinate nearly every volcanologist. There are volcanologists who peer inside tiny crystals to measure minuscule amounts of dissolved gas, and there are volcanologists who use spectroscopy — specifically studies of how minerals absorb ultraviolet light — to measure the copious gases billowing from a vent.
